| How to find a randomic ID on HTML page (Cucumber/Capybara) Posted: 31 Mar 2016 07:10 AM PDT I'm trying to test an application that generate tickets, so I have to open a ticket and then assume it. I'm having a problem with the part of assume it, because the tickets are opened with a random ID (the number of the ticket). <button type="submit" id="assign_ticket_6168218" class="btn btn-primary exchange_button"> <i class="fa fa-thumbs-up"></i> Assume
The number of id="assign_ticket_6168218" is random, but the other part is always the same. So, I'm creating the ticket and now I have to click on the button to assume it. How can I create a ticket and store the number of the ticket to use it on the ID? PS: If this is importante, when a create the ticket, I receive a confirmation message with the ticket's ID: `<div id="messages" class="clearfix"> <div class="success global alert-default form-section"> <ul> <li><i class="fa fa-check"></i>Ticket 6168218 created.</li> </ul> <a href="javascript:;" class="close-alert"><strong>x</strong></a> </div>

| Attribute translations for multiple Active Record models Posted: 31 Mar 2016 07:07 AM PDT I have several related-yet-distinct AR models that contain attributes representing the same piece of data. When I set up translations for these attributes, I'm currently setting them up as... en: activerecord: attributes: model_a: assigned_date: "Assigned to worker" model_b: assigned_date: "Assigned to worker" [ ... ]
Is there any way to define this translation once, in some kind of wildcard fashion? The approach I thought made the most sense... en: activerecord: attributes: assigned_date: "Assigned to worker" model_a: [ model-specific translations here ]
Doesn't work because AR is obviously looking for a model name at the tier beneath attributes |
| Nested forms creates empty instances Posted: 31 Mar 2016 07:02 AM PDT I have a Post and a MaterielLink models. A post has_many materiel_links, and accepts_nested_attributes_for :materiel_links I use the gem cocoon to create a nested form: on the post form, I want to be able to add links that will be created on submit of the form. post/new.html.erb: <%= simple_form_for @post, :html => { :id => "post_form", "data-post-id" => @post.id } do |f| %> <%= f.simple_fields_for :materiel_links do |materiel_link| %> <%= render 'materiel_link_fields', f: materiel_link %> <% end %> <%= link_to_add_association 'Ajouter', f, :materiel_links%> <% end %>
_materiel_link_fields.html.erb: <%= f.fields_for :materiel_links do |materiel_link| %> <%= materiel_link.text_field :name %> <%= materiel_link.text_field :link %> <% end %>
In my post controller: def update @materiel_links = @post.materiel_links.build(post_params[:materiel_links_attributes] if @post.update!(post_params) session[:current_draft_post_id] = nil redirect_to post_path(@post) else render :new end end
And the params: def post_params params.require(:post).permit(:title, materiel_links_attributes: [:name,:link] ) end
I added a raise in the update action, and what is stange is that I can find the link/name for each materiel_link I've added when I type params but with a number before each couple: >> params {"utf8"=>"✓", "_method"=>"patch", "authenticity_token"=>"wqzWfaAcwrOOdxViYBO5HaV2bwsNsf5HsvDFEbBYapkOMAPXOJR7oT4zQHbc/hTW8T9a+iH5NRl1WUApxrIjkA==", "post"=>{"title"=>"my title", "materiel_links_attributes"=>{"1459431927732"=>{"materiel_links"=>{"name"=>"mon Lien 1", "link"=>"htttp1"}}, "1459431933881"=>{"materiel_links"=>{"name"=>" Mon lien 2", "link"=>"htttp2"}}}}, "controller"=>"posts", "action"=>"update", "id"=>"1250"}
But nothing in the materiel_links hashes when I type post_params: >> post_params => {"title"=>"my title","materiel_links_attributes"=>{"1459431927732"=>{}, "1459431933881"=>{}}}
The instances of MaterielLink are created, but they are empty: they don't save the link/name. Where did I go wrong ? |
| Rails, abilities with cancancan Posted: 31 Mar 2016 06:53 AM PDT I am using cancancan to define abilities for my demo restaurant app. Each restaurant has_many employees and each employee has user_id and role attributes. I would like to allow a user to edit a restaurant only if this restaurant has an employee with user_id as the current_user.id and his role is 'manager'.

| Rails Inadvertantly Showing JSON in View Posted: 31 Mar 2016 06:29 AM PDT I'm using Rails 4 and have a weird issue in one of my views. In my controller I'm getting a weather feed from OpenWeatherMap.org using the Ruby_Open_Weather_Map gem. The data is returned as JSON and I am looping through the JSON and extracting the forcast information for the next 5 days. What's weird is that after my loop, the JSON data is displayed. 
I'm new to Rails and to JSON and this doesn't make any sense to me. I have a second page that has even more information on it and the same thing happens. This is what my controller looks like: def index options = { units: "Imperial", APPID: '6eff99d4b460d3a1acddcf1a727a7a45' } @currentweather = OpenWeather::Current.city("Greenville, SC", options) @forcastweather = OpenWeather::ForecastDaily.city("Greenville, SC", options) end
and this is what my view looks like: <%= @forcastweather['list'].each do | day | %> <div class ="row"> <div class="col-xs-5"> <strong><%= Time.at(DateTime.strptime(day['dt'].to_s,'%s')).in_time_zone("Eastern Time (US & Canada)").strftime("%A") %></strong> </div> <div class="col-xs-3"> <%= day['temp']['min'] %> </div> <div class="col-xs-3"> <%= day['temp']['max'] %> </div> <div class="col-xs-2"> <img src="http://openweathermap.org/img/w/<%= day['weather'][0]['icon'] %>.png" alt="<%= day['weather'][0]['main'].humanize %>"> </div> </div> <% end %>
Why is the JSON displaying in my view and how do I fix it? Thanks for your help with this. |

| How to combine two activerecord queries? Posted: 31 Mar 2016 06:23 AM PDT Lets say we have Event model, and SearchEngine class which performs searches on events. SearchEngine has search method.
class SearchEngine def search(event_scope) return Event.all if event_scope.nil? //event_scope combined with Event.where('name = ?','test') end end
I'd like to be able to pass event_scope like this: SearchEngine.new.search(Event.where('start_time > ?',Time.now))
And the result would be the same as: Event.where('start_time > ?',Time.now).where('name = ?','test')

| Ruby: Wrong number of arguments Error when calling method with a parameter with a default value Posted: 31 Mar 2016 06:37 AM PDT I'm working with PageObject and DataMagic to populate a form in a page, and I use a method to set the data, that has a parameter defined with a default value. I was able to call the method without defining any parameters(page.checkout), but after a change in the code it is giving me this error: wrong number of arguments (0 for 1) (ArgumentError) This is my code before the change, which works fine: class CheckoutPage include PageObject DEFAULT_DATA = { 'name' => Faker::Name.name, 'address' => Faker::Address.street_address, 'email' => Faker::Internet.email, 'pay_type' => 'Credit card' } text_field(:name, :id => "order_name") text_field(:address, :id => "order_address") text_field(:email, :id => "order_email") select_list(:pay_type, :id => "order_pay_type") button(:place_order, :value => "Place Order") def checkout(data = {}) populate_page_with DEFAULT_DATA.merge(data) place_order end end
But when I made this change, it started giving me the error message when called without parameters (works just fine if I call page.checkout(data_hash): class CheckoutPage include PageObject include DataMagic text_field(:name, :id => "order_name") text_field(:address, :id => "order_address") text_field(:email, :id => "order_email") select_list(:pay_type, :id => "order_pay_type") button(:place_order, :value => "Place Order") def checkout(data = {}) populate_page_with data_for(:checkout_page, data) place_order end end
I tested this to make sure it's not a problem with DataMagic, and I didn't get the Error, however, it makes no sense to my code, so it's not a possible solution: class CheckoutPage include PageObject include DataMagic DEFAULT_DATA = { 'name' => Faker::Name.name, 'address' => Faker::Address.street_address, 'email' => Faker::Internet.email, 'pay_type' => 'Credit card' } text_field(:name, :id => "order_name") text_field(:address, :id => "order_address") text_field(:email, :id => "order_email") select_list(:pay_type, :id => "order_pay_type") button(:place_order, :value => "Place Order") def checkout(data = {}) populate_page_with data_for(:checkout_page, DEFAULT_DATA.merge(data)) place_order end end
Shouldn't this method be creating an empty hash by default and therefore having the necessary parameters to do the action, whether I define parameters in the call or not? I'm using Ruby 2.2.5 |

| Rails/Rspec JSON integers being converted to strings when testing post call Posted: 31 Mar 2016 05:24 AM PDT I am testing a JSON request to our API, It will respond with JSON. It seems like all the integers within the JSON get converted to strings as we post them to the controller consider action.

The test log is showing that the request is Processing by Api::V1::CreditApplicationsController#consider as JSON
Inspecting the request just before the post action you will see the params are fine, then in the controller before I run anything I inspect the params and they are all strings. Using postman to test the API with the JSON works as expected but it seems that rspec when posting to the consider action will convert all the params to strings. I have read a few dozen posts that claim by adding format: :json to the post action it will remedy this, however I have had no such luck. I am obviously doing something wrong but I have tried pretty much everything I know. |

| Save each JSON object to a model Posted: 31 Mar 2016 07:04 AM PDT I'm looking to save each JSON object within the call to a model so I don't have to call the API every single time I load up the application, instead I call all the models entries. require 'httparty' require 'json' class Feed < ActiveRecord::Base include HTTParty base_uri 'https://www.parsehub.com/api/v2/projects' # GET /feeds # GET /feeds.json def boom response = self.class.get("/tVv8nTahbhgkyIUW8ByCe0-7/last_ready_run/data?&format=json") @elements = response.parsed_response["image"] @parsed = @elements.collect { |e| e['url'] } end
This is what I currently have within my model, which perfectly calls the API and displays each one of them within my view. Obviously this isn't the greatest way of doing this, I would like to save each of the JSON's URL property to my model - not entirely sure how to go about doing this! |
| Rails with Existing Database Model has no columns Posted: 31 Mar 2016 04:49 AM PDT Im developing a new rails app with an existing SQL SERVER 2008 database. I read somewhere that rails 4.2 doesn't support SQL SERVER 2008 so I downgraded to 4.1 (if this matters) I create a model using rails g model command then deleted the migration file class IpProject < ActiveRecord::Base self.table_name = 'IP_Projects' self.primary_key = "ProjectID" end
when I try to query IpProject.all.count
it shows the number of rows but I can't display the output I then tried to display the columns by IpProject.column_names
but it's an empty [] Could someone tell me what I'm missing here? By the way I'm using tiny_tds and activerecord-sqlserver-adapter |

| Sidekiq workers suddenly slowed down (almost like stuck workers) Posted: 31 Mar 2016 03:58 AM PDT I've been using sidekiq for a while now and it was working flawlessly (up to 5 million jobs processed). However in the past few days the workers got stuck and thus the jobs left unprocessed. Only by restarting the workers, they'll start working and consuming the jobs again, but they'll eventually stuck again (~10-30minutes, I haven't done any exact measurements). Here's my setup: - Rails v4.2.5.1, with ActiveJob.
- MySQL DB, clustered (with 3 masters)
- ActiveRecord::Base.connection_pool set to 32 (verified in Sidekiq process as well).
- 2 sidekiq workers, 3 threads per worker (total 6).
Symptons: If the workers just got restarted, they process the jobs fast (~1s). After several jobs processed, the time needed to complete a job (the same job that previously take only ~1s to complete) suddenly spiked to ~2900s, which make the worker look like stuck. The slows down affect any kind of jobs (there's no specific offending job). CPU usage and Memory consumption is normal and no swap either. Here is the TTIN log. It seems like the process hung when: - retrieve_connection
- clear_active_connections
But I'm not sure why it is happening. Anyone have similar experience or know something about this issue? Thanks in advance. |
| Access form_for object in corresponding controller method Posted: 31 Mar 2016 04:50 AM PDT I have a form_for, and I want to access variable of it in corresponding submit controller method. I'll explain what I mean: I have list of objects rendered as follows: <%= render medical_situations %>
I corresponding medical_situation.html.erb file I specify how each object looks like, where inside of each I have form_for as follows: <%= form_for medical_situation, {url: :send_to_pool_medical_situations, method: :post, remote:true} do |f| %>
In corresponding controller method I want to access that particular medical_situation object. Is it possible. I know I could pass medical_situation_id to find appropriate object but I am interested can I do it without extra request and code. In my send_to_poo method I want to do update that object. |
| Rails & JQuery: Invalid association. Make sure that accepts_nested_attributes_for is used for Posted: 31 Mar 2016 04:52 AM PDT Although I'd like to add link_to_add with using simple_nested_form_for, the following error was displayed. ArgumentError (Invalid association. Make sure that accepts_nested_attributes_for is used for :events association.):
There are similar questions in stackoverflow, but it doesn't work for me. So I post this as a new question. The error was appeared when I add f.link_to_add in _schedule_form.html.erb. _schedule_form.html.erb <%= f.label :title %> <%= f.text_field :title, class: 'form-control' %> <br> <%= f.label :departure_date %> <div class="input-group date" id="datetimepicker"> <%= f.text_field :departure_date, class: 'form-control' %> <span class="input-group-addon"> <span class="glyphicon glyphicon-calendar"></span> </span> </div> <script type="text/javascript"> $(function () { $('#datetimepicker').datetimepicker({format:'MMM-DD-YYYY'}); }); </script> <br> <div id="room"> <%= f.simple_fields_for :rooms do |a| %> <p class="day-number-element-selector"><b>Day <%= a.index.to_i + 1 %></b></p> <div id="event"> <% a.simple_fields_for :events do |e| %> <%= e.input :from %> <% end %> </div> #add here!!! <%= f.link_to_add "Add event", :events, data: {target: '#event'}, class: "btn btn-primary" %> <%= a.input :room %> <% end %> </div>
new_html.erb <div class="row"> <div class="col-md-12"> <p>Create schedule</p> <%= simple_nested_form_for(@schedule) do |f| %> <%= render 'schedule_form', f: f %> <%= f.submit "Create my schedule", class: "btn btn-primary" %> <br> <% end %> </div> </div>
Give the following models: class Schedule < ActiveRecord::Base belongs_to :user has_many :rooms accepts_nested_attributes_for :rooms, allow_destroy: true ... class Room < ActiveRecord::Base belongs_to :schedule has_many :events accepts_nested_attributes_for :events, allow_destroy: true ... class Event < ActiveRecord::Base belongs_to :room ...
schedule_controller.rb class SchedulesController < ApplicationController ... before_action :set_schedule, only: %i(show edit update destroy) ... def new @schedule = Schedule.new room = @schedule.rooms.build room.events.build end def create @schedule = current_user.schedules.build(schedule_params) if @schedule.save flash[:success] = "schedule created!" redirect_to root_url else render 'new' end end def edit @day_max = Room.where("schedule_id = ?", @schedule.id).maximum(:day) end def update @schedule.rooms.maximum(:day) if @schedule.update(schedule_params) flash[:success] = "schedule updated!" redirect_to root_url else render 'edit' end end private def schedule_params params.require(:schedule).permit(:title, :departure_date, rooms_attributes: [:id, :_destroy, :room, :day, events_attributes: [:id, :_destroy, :from, :to, :title, :detail]]) end def set_schedule @schedule = Schedule.find(params[:id]) end
No error have been displayed before adding link_to_add. It would be appreciated if you could give me any suggestion. |
| Rails console like console for symfony Posted: 31 Mar 2016 04:37 AM PDT Is there any console for symfony like we have for rails? In rails console we can access database tables and use rails active record code to get data. For example in rails we can do something like this User.first User.last User.all
And these commands will result first, last and all users from user table. Is there any similar thing in symfony? |
