| Rails, Is there a way to generate Unit Tests from Existing Controllers and methods defined in them? Posted: 01 Aug 2016 07:56 AM PDT 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. |
| Rendering two collections in rails Posted: 01 Aug 2016 07:48 AM PDT 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~ |

| Getting a log of Rails API calls (and responses) Posted: 01 Aug 2016 07:43 AM PDT 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? |

| Install gems on docker Posted: 01 Aug 2016 07:02 AM PDT 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! |
| Ruby How to convert back binary string from smsc Posted: 01 Aug 2016 06:49 AM PDT 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 Shmulik |

| Rails transaction rollback does not happen if after_create fails Posted: 01 Aug 2016 06:53 AM PDT 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? |
| RoR permitting non modal parameter Posted: 01 Aug 2016 06:04 AM PDT I'm having a hard time trying to understand how to permit non modal parameters. I've read: 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? |

| Multi timezone task scheduling in Rails (using whenever) Posted: 01 Aug 2016 05:38 AM PDT 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. |

| How to fix Cross Site Scripting security warning in rails generated by brakeman? Posted: 01 Aug 2016 08:04 AM PDT 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

| False Warning for mass assignment is thrown by Brakeman Gem in model.new and model.update_attibutes and model.create Posted: 01 Aug 2016 07:53 AM PDT 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 |
| Regex for combination of given rules Posted: 01 Aug 2016 05:30 AM PDT 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 |

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. 2.2.2 :001 > Job.near('sydney', 10 ) Job Load (97.5ms) SELECT jobs.*, 6371.0 * 2 * ASIN(SQRT(POWER(SIN((-33.8688197 - jobs.latitude) * PI() / 180 / 2), 2) + COS(-33.8688197 * PI() / 180) * COS(jobs.latitude * PI() / 180) * POWER(SIN((151.2092955 - jobs.longitude) * PI() / 180 / 2), 2))) AS distance, MOD(CAST((ATAN2( ((jobs.longitude - 151.2092955) / 57.2957795), ((jobs.latitude - -33.8688197) / 57.2957795)) * 57.2957795) + 360 AS decimal), 360) AS bearing FROM "jobs" WHERE (jobs.latitude BETWEEN -33.958751860591875 AND -33.77888753940813 AND jobs.longitude BETWEEN 151.10098469477293 AND 151.31760630522706 AND (6371.0 * 2 * ASIN(SQRT(POWER(SIN((-33.8688197 - jobs.latitude) * PI() / 180 / 2), 2) + COS(-33.8688197 * PI() / 180) * COS(jobs.latitude * PI() / 180) * POWER(SIN((151.2092955 - jobs.longitude) * PI() / 180 / 2), 2)))) BETWEEN 0.0 AND 10) ORDER BY distance ASC => #<ActiveRecord::Relation [#<Job id: 73, title: "Dog walkingn", description: "walk my dog everyday", price: "$25", user_id: "24", timeframe: "daily", created_at: "2016-07-29 05:50:00", updated_at: "2016-07-29 05:50:00", location: nil, job_type_id: "3", street_number: "100", street: "Pitt Street", suburb: "Sydney", state: "NSW", postcode: "2000", country: "Australia", longitude: 151.2092955, latitude: -33.8688197>]>
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! |
| Could not install gems on docker container Posted: 01 Aug 2016 03:41 AM PDT 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! |
| ActiveRecord::NestedAttributes::TooManyRecords error Posted: 01 Aug 2016 07:07 AM PDT 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? |
| Use Google::Auth::Stores::FileTokenStore with database Posted: 01 Aug 2016 04:32 AM PDT 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? Official documentation |
| Rails server jquery datatables pagination Posted: 01 Aug 2016 03:12 AM PDT 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 ?)

| Rails search with 2 select_tag Posted: 01 Aug 2016 07:02 AM PDT 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. |
| API-only Rails app with 'admin' and 'user' roles best practice Posted: 01 Aug 2016 03:09 AM PDT 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 |
