I was wondering if there is a script that can take existing codebase and generate unit tests for each method in controllers. By default all would be passing since they would be empty and i can remove tests i for methods i dont feel important.

This would save huge time and increase testing. Since i'd have to define only what each method should output and not boilerplate that needs to be written.

I am having trouble rendering two collections in rails. Essentially, I want the :html rendering the following collections to a string in one :html call:

:html => render_to_string( :partial => "day_notes", :locals => {:day_notes => day_notes, :date => date} )  :html => render_to_string( :partial => "events", :locals => {:events => events, :date => date} )  

What would be the format for doing such a thing? Any and all help is appreciated. Cheers~

I have created a form which has save and download button. I want the save button to be disabled until completion of all fields and download button to be disabled until the form is being saved.

I've got a Rails application which also contains an API part (through the /api route).

This works but I would like to have one of the following options:

• Have a rolling log (for example keep the last 100 calls and responses) and visualise this in the web application.
• Have the option (in the web application) to enable monitoring and when it's enabled display all calls and responses that are made to the API.

I'm hoping I'm not the first to look for something like this. Are there any gems available that suit this purpose?

I have been trying post JSON data via POSTMAN but I get param is missing or the value is empty: stall. can someone please tell me where I'm going wrong ?

 def create     @stall = Stall.new(stall_params)           if @stall.save           render json: @stall, status: :created         else             render json: @stall.errors, status: :unprocessable_entity      end    end        private  def stall_params    params.require(:stall).permit(:name, :place)  end  

My Table contains only two columns name and place

Below is the log Processing by API::V1::StallsController#create as JSON Parameters: {"name"=>"trill", "place"=>"trill"} Completed 400 Bad Request in 0ms (ActiveRecord: 0.0ms)

I am interested in getting all attributes or column_names from a Ruby Model which belong to a certain class. Not able to find a way to achieve it. Please let know if anyone has solution to it.

E.g.:  -Get all column_names belonging to class ActiveSupport::TimeWithZone    -Output:  ['created_at','updated_at','delivery_date','packed_date']  

I create new payment

def new      @contract = Contract.find(session[:contract_id])      # Register card for user      @card_preregistration = MangoPay::CardRegistration.create({          UserId: current_user.mangopay_id,          Currency: "EUR",          CardType: "CB_VISA_MASTERCARD"        })      session[:card_id] = @card_preregistration['Id']      locals card_reg: @card_preregistration    end  

pass all data to url payment server with ajax.

register_card.coffee

jQuery ->    $('#payment-form').submit (e) ->      e.preventDefault()        $this = $(this)        mangoPay.cardRegistration.init        cardRegistrationURL: $("#CardRegistrationURL").val()        preregistrationData: $("#PreregistrationData").val()        accessKey: $("#AccessKey").val()        cardData = {        cardNumber: $("#card_number").val()        cardExpirationDate: $("#card_expiration_date").val()        cardCvx: $("#cardCvx").val()      }        mangoPay.cardRegistration.sendDataWithAjax(        # URL to capture response        "http://site:8080/finialize",        # Card data        cardData,        # Result Ajax callback        (data) ->          #console.log(data)        # Error Ajax callback        (xhr, status, error) ->           alert("Payment error : " + xhr.responseText + " (" + status + " - " + error + ")")        )      #cons  

After run method finialize_payment:

def finialize_payment      binding.pry      card_registration = MangoPay::CardRegistration.update(session[:card_id], {          RegistrationData: "data=#{params['data']}",          Tag: "custom tag"        })      end  

session[:card_id] is nill. How pass variable @card_preregistration from new to finialize_payment?

I develop an app using rails and Docker. I faced an issue: when I run

docker-compose -f dcom-dev.yml run --user $(id -u)  web gem install google-api-client  

it runs good, but if I write to my Gemfile gem 'google-api-client' and then run

docker-compose -f dcom-dev.yml run --user $(id -u)  web bundle install  

it failes with several warnings like this:

Errno::ENOENT: No such file or directory @ rb_sysopen - /.gem/ruby/2.3.0/cache/memoist-0.14.0.gem  

and an error like this:

An error occurred while installing memoist (0.14.0), and Bundler cannot continue.  Make sure that `gem install memoist -v '0.14.0'` succeeds before bundling.  

If I run gem install manually, it works fine, but bundle install throws error about another gem (little-plugger). If I install the second gem manually, bundler throws message about the first gem (memoist) again and it repeats again and again. What could I do with this? Thanks in advance!

my app work with SMSC, and i need to get involve in sms before it send,

i try to send from the mobile that string

"hello this is test"

And when I check the smsc I got this as binary string of my text:

userData = "c8329bfd06d1d1e939283d07d1cb733a"  

the encoding of this string is:

<Encoding:ASCII-8BIT>  

I know that probably this userData is in GSM encoding in binary-string

so how can i get from userData back the clear text string ?

this question is for english lang, because in Hebrew I can get back the string with this code:

[userData].pack('H*').force_encoding('utf-16be').encode('utf-8')

but in english i got error:

Encoding::InvalidByteSequenceError: "\xDA\xF3" followed by "u" on UTF-16BE  

What I was try is to detect the binary string with ICU, and I got:

"ISO-8859-1" and the language that detected is: 'PT', that very strange cause my languages is English or Hebrew.

anyway i got lost with encoding stuff, so i try to encode to each name of list from Encoding.list

but without luck until now

thanks in advance

I have a worker with one perform class. In the controller I am calling up that worker class. When I call it up with worker.perform.now I see in console that perform method is being executed as I want it.

How to schedule this callup in controller, to be performed every day at ten o'clock?

PS: When I call worker.perform_async it doesn't do anything.

In my User model I have a after_created callback as

after_create :count_files  def count_files    errors[:base] << "error working"    errors.add(:base, "error working")            return false  end  

As you can see, I am always adding base errors and returning false always, but still user is created. I think, if after_create returns false then automatic rollback happens instead of saving data in database. But for my case, data is always saving in database and transaction rollback doesn't happen. Why is that? how can I prevent user from being created if my after_create fails?

I'm having a hard time trying to understand how to permit non modal parameters.

I've read:

• Rails Strong Parameters: How to accept both model and non-model attributes?
• Rails 4 Strong parameters : permit all attributes?

So, for a "normal" situation - let's say that I have a model Foo which has just one attribute bar:

# foo.rb  class Foo < ActiveRecord::Base    # bar, which is a integer  end    # views/foos/new.html.erb  <%= form_for @foo do |f| %>      <%= f.number_field :bar %>      <%= f.submit %>  <% end %>    #foos_controller.rb  def create      @foo = Foo.new(foo_params)      # ...  end    #...    private    def foo_params      params.require(:foo).permit(:bar)  end  

So, when I submit the form, the Foo will be created.

However, what if the bar attribute has some logic behind it that combines some non modal parameters? Let's say that bar is the sum of two parameters (bar = bar_1 + bar_2). Then the view and controller looks like:

# views/foos/new.html.erb  <%= form_for @foo do |f| %>      <%= f.number_field :bar_1 %>      <%= f.number_field :bar_2 %>      <%= f.submit %>  <% end %>    #foos_controller.rb  def create    bar_1 = params[:bar_1]    bar_2 = params[:bar_2]      if bar_1.present? && bar_2.present?      @foo = Foo.new      @foo.bar = bar_1.to_i + bar_2.to_i        if @foo.save        # redirect with success message      else        # render :new      end    else      # not present    end  end  

So the question is, do I also need to permit the bar_1 and bar_2 parameters? If I do, how do I permit them?

Heroku keeps rejecting my pushes with this error:

 Make sure that `gem install sqlite3 -v '1.3.11'` succeeds before bundling.  remote:  !  remote:  !     Failed to install gems via Bundler.  remote:  !       remote:  !

I realize this is a common problem (I have looked at other threads) I have tried removing the sqlite3 gem from my Gemfile, I ran a bundle install and made sure that the sqlite3 gem was also out of my Gemfile.lock (which it was).
I also got rid of all references to sqlite3 from my database.yml and replaced them with Postgres:

I'm lost any suggestions?

We're currently using 'whenever' to schedule jobs in a Rails project. The system is expanding to support users in multiple timezones (timezone is stored in User model) and we would like to send users an email at a specific time of THEIR day.

Any ideas on the best pattern to achieve this? I'm foreseeing 24 (or more - there are half timezones) 'whenever' tasks per email job each with a different timezone filter on the user table.

Any ideas for a cleaner solution? A better scheduler than whenever perhaps? Something that will create the 24/48 cronjobs and call a callback passing a timezone or a UTC offset? Something like that.

So i have a car class which have many photos. And When creating a new car i need to ensure that the user did select a picture first. Here is the implementation.

class Car < ActiveRecord::Base   has_many :photos  end  

and class photo:

class Photo < ActiveRecord::Base  belongs_to :car    has_attached_file :image, styles: { medium: "300x300>", thumb: "100x100>" }  validates_attachment_content_type :image, content_type: /\Aimage\/.*\Z/  end  

Here is a part of the car form:

  <%= form_for @car, :html => { multipart: true } do |f| %>                <div class="col-xs-6">                  <div class="form-group">                      <label>Modele</label>                      <%= f.text_field :modele, placeholder: "Modele", class: "form-control" %>                  </div>              </div>                  <div class="row">                  <div class="col-md-4">                      <div class="form-group">                                                      <span class="btn btn-default btn-file">                              <i class="fa fa-cloud-upload fa-lg"></i> Upload Photos                               <%= file_field_tag "images[]", type: :file, multiple: true %>                          </span>                      </div>                        </div>              </div>     <% end %>  

I used brakeman for generating scanning reports in my application. It generated many Cross Site Scripting security warnings with High Confidence. In that one of them is:

Unescaped parameter value rendered inline near line 47: render(text => "Unexpected EventType #{params["EventType"]}", { :status => 406 }) app/controllers/event_controller.rb. In the controller method shown below, the 1st line is showing the above warning.

I have seen in the link but couldn't fix. Please help. And this is controller code:

  def purchase        render :status => 406, :text => "Unexpected EventType #{params['EventType']}" and return unless params['EventType'] == 'purchased'      @account = Account.new      render :status => 406, :text => "Could not find Plan #{params['Plan']}" and return unless @account.plan = @plan = SubscriptionPlan.find_by_name(params['Plan'])      end  

Mass assignment is a feature of Rails which allows an application to create a record from the values of a hash. There are two different mass assignment warnings which can arise. The first is when mass assignment actually occurs. Example:-

User.new(params[:user])  

Although I am not using a hash directly to map with the fields available in the table. Instead I am doing something like:

User.new(:first_name => params[:first_name], :last_name => params[:last_name ], :address => params[:address])  

or

user.update_attributes(:first_name => params[:first_name], :last_name => params[:last_name ], :address => params[:address])  

Why is this leading to a Mass Assignment Vulnerability? As I am not blindly assigning a hash, I am selectively updating only few of the attributes of the table.

One fix for this is by doing the following:

user = User.new  user.first_name = params[:first_name]  user.last_name = params[:last_name ],  user.address = params[:address]  user.save  

But this is like writing unnecessary code, so that the Brakeman is not alerting this as an issue. This is actually doing the same thing in 4 lines instead of a single line.

Can somebody please make me understand what is the actual issue here or confirm that this is a false alert and also is there any way that we can prevent this false alert to appear?

I am using ruby 1.8.7, Rails 2.3.2, Brakeman 3.0.5

I'm trying to write regex to validate the password for the given rule.

Passwords must be at least 8 characters in length and contain at least 3 of the following 4 types of characters:

• lower case letters (i.e. a-z)
• upper case letters (i.e. A-Z)
• numbers (i.e. 0-9)
• special characters (e.g. !@#$&*)

I was going through this discussion and found this really great answer over there.

Now I'm trying to write regex for the mentioned requirements and I came up with the solution like this

^(?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).{8,}|  (?=.*[!@#$&*])(?=.*[0-9])(?=.*[a-z]).{8,}|  (?=.*[A-Z])(?=.*[0-9])(?=.*[a-z]).{8,}|  (?=.*[A-Z])(?=.*[!@#$&*])(?=.*[a-z]).{8,}|  (?=.*[A-Z])(?=.*[!@#$&*])(?=.*[0-9]).{8,}$  

and it is working perfect see rubular but I want to optimize these regex and I'm not sure If there are any way to simplify this. Any suggestion will be appreciated. Many thanks

When the form is submitted all that is in the params hash is the controller and action. None of the form values are present. I have tested and all that is returned is

{"controller"=>"show", "action"=>"create_user"}

I am trying to build an app with Rails that allows users to search for job listings using geographic locations (addresses to be specific). I'm using the 'geocoder' gem.

gem 'geocoder'

I can successfully search using the rails console using Job.near('sydney',10) and it returns a listing from my database in an array.

But when I do this in controller and try and send the data to the view (jobs.html.erb), all I get is :

#<Job::ActiveRecord_Relation:0x007fd66475abd8>  

here is my controller code:

def location

if params[:location].present?    jobs = Job.near(params[:location],     params[:proximity])      @jobs = jobs  else    @noJobs = 'there is nothing nearby'    @jobs = nil  end  

end

and my view only consists of: (jobs.html.erb)

 <%=  @jobs %>         

can anyone explain to me what is going on and how i can access the data? and what the active record relation actually means?

I'm still pretty new to coding, and this has completely stumped me. I cant find the answer anywhere. Really appreciate any help, Thanks!

I'm developing a Rails app using Docker. Now I need to install a new gem, but that does not work.

If I run docker-compose -f dcom-dev.yml run --user $(id -u) web bundle exec gem install youtube_it it gives me such an output:

Fetching: excon-0.51.0.gem (100%)  ERROR:  While executing gem ... (Errno::ENOENT)      No such file or directory @ rb_sysopen - /.gem/ruby/2.3.0/cache/excon-0.51.0.gem  

If I add gem 'youtube_it' to my Gemfile and then run docker-compose -f dcom-dev.yml run --user $(id -u) web bundle exec bundle install it outputs like this:

Could not find gem 'youtube_it' in any of the gem sources listed in your Gemfile or available on this machine.  Run `bundle install` to install missing gems.  

What could be a problem? Thanks in advance!

In my app, when user register they can upload some files. I need to limit the upload to maximum 5 files. So I have two model with following code

class User < ActiveRecord::Base  has_many :fileuploads, :dependent => :destroy    accepts_nested_attributes_for :fileuploads, limit: 5, :allow_destroy => true      validate do |user|      if user.fileuploads && user.fileuploads.count > 5        errors[:base] << "You can add maximum 5 files."      end    end    end  

and

class Fileupload < ActiveRecord::Base    belongs_to :user  end  

and in my create and update action I added

respond_to do |format|    begin      if @user.save        format.html { redirect_to @user, notice: I18n.t('views.flash_messages.user_was_successfully_created') }      else        format.html { render action: "new" }      end    rescue ActiveRecord::NestedAttributes::TooManyRecords      flash[:error] = 'You can add maximum 5 files. '    end  end  

As you can see from the code above that, I am using limit: 5 and also the validate callback. But both works perfect when I update the user. But when user is created, this error message is not rescued at all. I get this error,

ActiveRecord::NestedAttributes::TooManyRecords in UsersController#create  Maximum 5 records are allowed. Got 7 records instead.  

So why the limit and validate works during user update but not during user creation? And how to make it work for create action as well?

I'm trying to implement a 3 legged authentication in my app to the Google API, to be able to access registered users' Google Calendars.

In the quickstart Ruby guide, this command comes up that as far as I understand should point to the user's tokens:

token_store = Google::Auth::Stores::FileTokenStore.new(file: CREDENTIALS_PATH)  

It expects the tokens stored in a file (or Redis), but (of course) I store each user's tokens in my database (Postgres).

Have I understand the purpose of the command wrongly or otherwise - how do I use it with a database store?

Because of low performance I change all my jquery datatables data to server side (include paging and sorting)

I want to know what the best way to build the query dynamically.

When the query run? In this row carts = Activity.where("sid=33")

Or just when run .each carts.each do |key,val|

This is my code

  def cart_activits_service_search        @site = get_site()        @site_id = @site.idsite        @from_date = params['from'] ? Time.zone.local_to_utc(DateTime.strptime(params['from'], "%Y-%m-%d")) : 6.days.ago.beginning_of_day        @to_date = params['to'] ? Time.zone.local_to_utc(DateTime.strptime(params['to'], "%Y-%m-%d")) : 0.days.ago.to_datetime        limit = 10        limit = params[:iDisplayLength] if params[:iDisplayLength].present?        q = params[:sSearch]        carts = CartActivity.where("idsite = :site_id and server_time between :from_date and :to_date",:site_id => @site.id,:from_date => @from_date, :to_date => @to_date+1.day)        @total_count = carts.count        @sEcho = params[:sEcho]        #where        carts =carts.where(" (email like ?) or (traffic_source like ?) or (event like ?) or (recovery_source like ?) ", "%#{params[:sSearch]}%", "%#{params[:sSearch]}%" , "%#{params[:sSearch]}%", "%#{params[:sSearch]}%") if params[:sSearch].present?          @count = carts.count        carts = carts.order("email")        carts = carts.limit(limit).offset(params[:iDisplayStart])          ret ={}        ret["sEcho"] = @sEcho        ret["iTotalRecords"] = @total_count        ret["iTotalDisplayRecords"] = @count        ret["aaData"] = []          carts.each do |key,val|            @temp =[]            @temp << key.email            @temp << key.server_time            @temp << key.traffic_source            @temp << key.event            @temp << key.recovery_source            @temp << key.cart_total            @temp << key.cart_items            ret["aaData"] << @temp        end          render :json =>  ret             end  

I'd like to use two select_tags for my search. Actually, it all works fine separately, but I'd like to use choose one option in a first/second tag, then the search begins, and later - choose an option in a second/first tag, and see more detailed search result. For now, I have:

Product model:

class Product < ApplicationRecord    belongs_to :position    has_and_belongs_to_many :size  end  

Size model:

class Size < ApplicationRecord    has_and_belongs_to_many :products    has_many :items  end  

Position model:

class Position < ApplicationRecord    has_many :products  end  

My application.html.erb:

<div class="container">      <div class="row text-center">        <div class="col-sm-6">          <%= form_tag(products_path, method: 'GET', remote: true) do %>            <%= select_tag 'size_id', options_from_collection_for_select(Size.all, 'id', 'title'),                           onchange: ('this.form.submit();'), class: 'form-control', id: 'filter1', include_blank: true %>          <% end %>        </div>        <div class="col-sm-6">          <%= form_tag(products_path, method: 'GET') do %>            <%= select_tag 'position_id', options_from_collection_for_select(Position.all, 'id', 'title'),                           onchange: ('this.form.submit();'), class: 'form-control', id: 'filter2', include_blank: true %>          <% end %>        </div>      </div>    </div>  

And a products_controller:

class ProductsController < ApplicationController    def index          if params[:position_id]        position = Position.find(params[:position_id])        @products = position.products        respond_to do |format|          format.html          format.json { render json: @products }        end      elsif params[:size_id]        size = Size.find(params[:size_id])        @products = size.products        respond_to do |format|          format.html          format.json { render json: @products }        end      else        @products = Product.all        respond_to do |format|          format.html          format.json { render json: @products }        end      end    end  end  

So, how can I do a search that will work not separately? Thanks ahead.

I am rebuilding a standard app in Rails (backend + rendering) and looking into creating API-only Rails backend and Node/React frontent.

I'm a little bit riddled on best practices here.

In my old app I had 2 devise models - User and Admin (admin was a separate namespace, so User would not have access to its controllers).

How would you recommend to implement sets of different controllers for admins and users?

Thanks
