  • Need a push in the right direction, to write my first functional test in Rails

    - by Jason
    I've read quiet a bit of documentation over the last few days about testing in Rails, I'm sitting down to write my first real test and not 100% sure how to tie what I have learned together to achieve the following functional test (testing a controller) I need to send a GET request to a URL and pass 3 parameters (simple web-service), if the functionality works the keyword true is simply returned, otherwise the keyword false is returned - its in only value returned & not contained in any <div>, <span> or other tags. The test should assert that if "true" is returned the test is successful. This is probably very simple so apologies for such a non-challenging question. If anyone could point me in the write direction on how I can get started, particularly how I can test the response, I'd be very grateful!

  • Translate Prototype code into Jquery version

    - by user1055495
    I everybody, I'm working on a SaaS application and I need to use Jquery instead of Prototype due to some extra plugins integration. My code that was wotking a charm with Prototype is not running anymore with Jquery and I'm not used to write in this framework... Is there someone to help me in "translating" this one: Thanks a lot for your help. var rates = new Array(); <% for tva_rate in @tva_rates -%> rates.push(new Array(<%= tva_rate.id %>, '<%=h tva_rate.taux %>', '<%=h tva_rate.compte_id %>' )); <% end -%> function tvaSelected() { tva_id = $('journal_tva_id').getValue(); show = 1; if (tva_id > 0){ rates.each(function(rate) { if (rate[0] == tva_id) { $('journal_taux').setValue(rate[1]); $('journal_compte_tva').setValue(rate[2]); show = 2; } }); } if (show == 1) { $('tva_taux_field').hide(); } else { $('tva_taux_field').show(); } } document.observe('dom:loaded', function() { tvaSelected(); $('journal_tva_id').observe('change', tvaSelected); });

  • Problems deploying Sinatra app to staging environment

    - by chris
    I have a small Sinatra app with both a staging and production environment on a single server with running Nginx. To deploy I am using Capistrano and capistrano-ext to easily deploy to different locations. The problem that the staging environment always runs with the production configuration specified within the app.rb file. configure :staging do # staging settings set :foo, "bar" end configure :production do # prod settings set :foo, "rab" end I have come to the conclusion that the capistrano :environment variable within the deploy.rb file doesn't config Sinatra in any way. I have also tried setting the ENV["RACK_ENV"] to "staging" to no avail. config/deploy/staging.rb server "10.10.100.16", :app, :web, :db, :primary => true set :deploy_to, "/var/www/staging.my_app" set :environment, "staging" set :env, "staging" ENV["RACK_ENV"] = "staging" Any ideas?

  • How many of you have gone from MySQL to Postgresql? Was it worth it?

    - by trustfundbaby
    I'm thinking about moving from MySQL to Postgres for Rails development and I just want to hear what other developers that made the move have to say about it. I'm looking for personal experiences, not a Mysql v Postgres shootout, just the pros and cons that you yourself have arrived at. Stuff that folks might not necessarily think. Feel free to explain why you moved in the first place as well.

  • How to add or remove a value inside a table cell on selection / de-selection of checkbox of that row, trying to submit the value via Jquery?

    - by Raul
    Here is the table: <%= form_tag '', :id => "costs" do %> <table class="table table-bordered" id="service_cost"> <% @services.each do |service| %> <tbody> <tr> <td><%= check_box_tag :open_service, {}, false, :class => 'checkable' %></td> <td><%= service.phone %></td> <td><%= service.internet %></td> <td></td> <td></td> <td></td> <td></td> <td></td> <td><%= service.house_keeping %> </td> <td>0.0 </td> <td><%= service.laundry %></td> <td><%= text_field_tag "service_cost", service.total, :class => "input-small" %></td> </tr> <% end %> when the form gets submitted, the javascript gets into action: $("#costs").submit(function(){ formData=$("#costs").serializeArray(); processFormData(formData) return false; }); This ensures form submission on selecting the checkbox: $('.checkable').live('change', function() { $(this).parents('form:first').submit(); }); But, what I am looking for is adding or removing a cell value based on checkbox selection/de-selection and submitting it, kindly suggest a way to do it.

  • What is the subject of Rspecs its method

    - by Steve Weet
    When you use the its method in rspec like follows its(:code) { should eql(0)} what is 'its' referring to. I have the following spec that works fine describe AdminlwController do shared_examples_for "valid status" do it { should be_an_instance_of(Api::SoapStatus) } it "should have a code of 0" do subject.code.should eql(0) end it "should have an empty errors array" do subject.errors.should be_an(Array) subject.errors.should be_empty end #its(:code) { should eql(0)} end describe "Countries API Reply" do before :each do co1 = Factory(:country) co2 = Factory(:country) @result = invoke :GetCountryList, "empty_auth" end subject { @result } it { should be_an_instance_of(Api::GetCountryListReply) } describe "Country List" do subject {@result.country_list} it { should be_an_instance_of(Array) } it { should have(2).items } it "should have countries in the list" do subject.each {|c| c.should be_an_instance_of(Api::Country)} end end describe "result status" do subject { @result.status } it_should_behave_like "valid status" end end However if I then uncomment the line with its(:code) then I get the following output AdminlwController Countries API Reply - should be an instance of Api::GetCountryListReply AdminlwController Countries API Reply Country List - should be an instance of Array - should have 2 items - should have countries in the list AdminlwController Countries API Reply result status - should be an instance of Api::SoapStatus - should have a code of 0 - should have an empty errors array AdminlwController Countries API Reply result status code - should be empty (FAILED - 1) 1) NoMethodError in 'AdminlwController Countries API Reply result status code should be empty' undefined method code for <AdminlwController:0x40fc4dc> /Users/steveweet/romad_current/romad/spec/controllers/adminlw_controller_spec.rb:29: Finished in 0.741599 seconds 8 examples, 1 failure It seems as if "its" is referring to the subject of the whole test, namely AdminLwController rather than the current subject. Am I doing something wrong or is this an Rspec oddity?

  • Rails is not passing the "commit" button parameter

    - by Wayne M
    Reinstalling a Rails app on a new server. Part of the app can fork in one of two directions based on the button the user selects. This part isn't working, and when I look at the log I see the values that I gave the form, execept for the commit portion of the params hash. This seems to be why the app isn't working as expected (since there's nothing in params[:commit], but I have no idea why commit would not be passed in; the request is definitely a POST request, and all of the other parameters are there.

  • Redirecting all page queries to the homepage in Rails

    - by Dean Putney
    I've got a simple Rails application running as a splash page for a website that's going through a transition to a new server. Since this is an established website, I'm seeing user requests hitting pages that don't exist in the Rails application. How can I redirect all unknown requests to the homepage instead of throwing a routing error?

  • jruby/activerecord-jdbc/tomcat/DB2 ready for enterprise?

    - by arkadiy
    I am trying to introduce RoR to my company and I have two ways of doing so in my mind: (1) rails/ibm_db2/passenger/DB2 - which is my preferable way but it is not really supported by company's infrastructure. (2) jruby/activerecord-jdbc/tomcat/DB2 - probably easier way to migrate relying on current infrastructure and java libs IF I have a proof this is an enterprise ready technology. Does anyone know if there is any prof that jruby/aciverecord-jdbc-adapter/DB2/tomcat is mature enough for production? Are there any problems I should know about during Development/Deployment/Runtime? My webapp is for a company intranet, around 200~400 active users.

  • ActiveRecord Validations for Models with has_many, belongs_to associations and STI

    - by keruilin
    I have four models: User Award Badge GameWeek The associations are as follows: User has many awards. Award belongs to user. Badge has many awards. Award belongs to badge. User has many game_weeks. GameWeek belongs to user. GameWeek has many awards. Award belongs to game_week. Thus, user_id, badge_id and game_week_id are foreign keys in awards table. Badge implements an STI model. Let's just say it has the following subclasses: BadgeA and BadgeB. Some rules to note: The game_week_id fk can be nil for BadgeA, but can't be nil for BadgeB. Here are my questions: For BadgeA, how do I write a validation that it can only be awarded one time? That is, the user can't have more than one -- ever. For BadgeB, how do I write a validation that it can only be awarded one time per game week?

  • Rails + simple role system through associative table

    - by user202411
    So I have the Ninja model which has many Hovercrafts through ninja_hovercrafts (which stores the ninja_id and the hovercraft_id). It is of my understanding that this kind of arrangement should be set in a way that the associative table stores only enough information to bind two different classes. But I'd like to use the associative table to work as a very streamlined authorization hub on my application. So i'd also like this table to inform my system if this binding makes the ninja the pilot or co-pilot of a given hovercraft, through a "role" field in the table. My questions are: Is this ugly? Is this normal? Are there methods built into rails that would help me to automagically create Ninjas and Hovercrafts associations WITH the role? For exemple, could I have a nested form to create both ninjas and hcs in a way that the role field in ninjas_hovercrafts would be also filled? If managing my application roles this way isn't a good idea, whats the non-resource heavy alternative (my app is being designed trying to avoid scalability problems such as excessive joins, includes, etc) thank you

  • rails: has_many :through + polymorphism validation?

    - by ramonrails
    I am trying to achieve this. Any hints? A project has many users through join model A user has many projects through join model Admin class inherits User class. It also has some Admin specific stuff. Admin like inheritance for Supervisor and Operator Project has one Admin, One supervisor and many operators. Now I want to 1. submit data for project, admin, supervisor and operator in a single project form 2. validate all and show errors on the project form. Project has_many :users, :through = :projects_users User has_many :projects, :through = :projects_users ProjectsUser = :id integer, :user_id :integer, :project_id :integer, :user_type :string ProjectUser belongs_to :project, belongs_to :user, :polymorphic = true Admin < User Supervisor < User Operator < User Is the approach correct? Any and all suggestions are welcome.

  • jquery $.ajax not working in firefox against rails (406 response) (works in chrome & IE)

    - by phil swenson
    I have a rails backend and am testing the following jquery code against it: var content = $("#notification_content").val(); var data = new Object(); data.content = content; $.ajax({ url: "/notifications/detect_type.json", type:"POST", data: data, success: function(result ){updateTypeDropDown(result)}}); This code works fine in Chrome and IE. However in Firefox (using Firebug), I see this: http://localhost:3000/notifications/detect_type.json 406 Not Acceptable here is a chrome request in the log: Processing NotificationsController#detect_type (for 127.0.0.1 at 2010-12-21 17:05:59) [POST] Parameters: {"action"="detect_type", "content"="226 south emerson denver co 80209", "controller"="notifications"} User Columns (2.0ms) SHOW FIELDS FROM users User Load (37.4ms) SELECT * FROM users WHERE (users.id = '1') LIMIT 1 Completed in 58ms (View: 1, DB: 40) | 406 Not Acceptable [http://localhost/notifications/detect_type.json] here is a firefox request in the log: Processing NotificationsController#detect_type (for 127.0.0.1 at 2010-12-21 17:06:41) [POST] Parameters: {"action"="detect_type", "content"="226 south emerson 80209", "controller"="notifications"} User Columns (2.1ms) SHOW FIELDS FROM users User Load (30.4ms) SELECT * FROM users WHERE (users.id = '1') LIMIT 1 Completed in 100ms (View: 1, DB: 33) | 200 OK [http://localhost/notifications/detect_type.json] I'm stumped.

  • Rails partial gets double escaped when using link_to_function

    - by dombesz
    Hi, I have the following code. def add_resume_link(name, form) link_to_function name do |page| html = form.fields_for :resumes, @general_resume.resumes.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial => 'resume_form', :locals=>{:form=>form_parent} end page << "$('resumes').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, id) });" end end And on the resume_form i have somewhere: =add_skill_link("Add Skill", form, "resume_#{id}_skills") and the function looks like: def add_skill_link(name, form, id) link_to_function name do |page| html = form.fields_for :skill_items, @general_resume.skill_items.build, :child_index => 'NEW_RECORD' do |form_parent| render :partial=>'skill_form', :locals=>{:form=>form_parent, :parent=>id} end page << "$('#{id}').insert({ bottom: '#{escape_javascript(html)}'.replace(/NEW_RECORD/g, new Date().getTime()) });" end end So basically i have a javascript code which dinamically adds a piece of html (add_resume) and contains another javascript code which dinamically adds a select box to the page. My problem is that the add_skill_link works fine if i use from the server side, i mean rendering from server side. And gets double escaped when using within the upper described way. I tried to remove the escape_javascript from the add_skill_link bit still not good. Any ideas?

  • Conditional value for ActiveRecord create method only

    - by Steve Wright
    I have a form where I have an administrator creating new users. The form uses the User model I created (login, password, first_name, etc...). For the last field on the form, I want to have a checkbox that doesn't need to be stored as part of the User record, but it is needed for the controller. This will control whether or not the newly created user will receive a welcome email or not. def create @user = User.new(params[:user]) if @user.save if @user.send_welcome_email UserMailer.welcome_email(@user).deliver end redirect_to(admin_users_url, :notice => "User #{@user.name} was successfully created.") else render :action => "new" end end In my view (haml) I am trying to access it like this: %p Send Welcome Email? = f.check_box :send_welcome_email I tried to make this an attr_accessible: :send_welcome_email but the controller does not recognize it. I get an undefined method 'send_welcome_email' for #&lt;User:0x00000100d080a8&gt; I would like it to look like this: What is the best way to get this working:

  • How do I do a count on that meet a specific condition, dependent on several has_many relationships i

    - by Angela
    I have a Model Campaign. A Campaign has many Events. Each Event has an attribute :days. A Campaign also has_many Contacts. Each Contact as a :date_entered attribute. The from_today(contact,event) method returns a number, which is the number of days from the contact's :date_entered till today minus the event's :days. In other words, a positive number shows the number of days from today till the :days of the event is elapsed. If it is negative, if means that the number of days that has elapsed since the :date_entered is greater than the :days attribute of an event. In other words, the event is overdue. What I would like to be able to do is do campaign.overdue and this would result in a total number of contacts that have an overdue event. It shouldn't count multiple events for a single contact, just one contact. How do I do that? It seems like I would need to cycle through all the events for every contact and keep a counter but I'm assuming that there is a better way.

  • Refactoring multiple if statements for user authentication with subdomains

    - by go minimal
    I'm building a typical web app where once a user signs up they access the app through their own subdomain (company.myapp.com). The "checking what kind of user if any is logged in" piece is starting to get very hairy and it obviously needs to be well-written because its run so often so I was wondering how you guys would re-factor this stuff. Here are the different states: A user must be logged in, the user must not have a company name, and the sub-domain must be blank A user must be logged in, the user must have a company name, that company name must match the current sub-domain A user must be logged in, the user must have a company name, that company name must match the current sub-domain, and the user's is_admin boolean is true if !session[:user_id].nil? @user = User.find(session[:user_id]) if @user.company.nil? && request.subdomains.first.nil? return "state1" elsif [email protected]? if @user.company.downcase == request.subdomains.first.downcase && [email protected]_admin return "state2" elsif @user.company.downcase == request.subdomains.first.downcase && @user.is_admin return "state3" end end end

  • Radius of multiple latitude/longitude points

    - by zekial
    I have a program that takes as input an array of lat/long points. I need to perform a check on that array to ensure that all of the points are within a certain radius. So, for example, the maximum radius I will allow is 100 miles. Given an array of lat/long (coming from a MySQL database, could be 10 points could be 10000) I need to figure out if they will all fit in a circle with radius of 100 miles. Kinda stumped on how to approach this. Any help would be greatly appreciated.
