  • Build model with nested model in rspec integration test

    - by user1116573
    I understand that I can do something like in rspec: let(:project) { Project.new } but in my app a project accepts_nested_attributes_for tasks and when I generate the Project form I build a task along with it using: @project = Project.new @project.tasks.build I need something like: let(:project) { Project.new.tasks.build } but that doesn't seem to work. How can I do this as a let in my rspec test?

  • How do I get AuthLogic to skip Password validation?

    - by ndp
    I think I'm just missing something obvious. I send a user a perishable token embedded in a link. They click on it, and they come back to the site. I want to log them in automatically (I'm not building a banking app). This seems like this should be simple, but all the examples I've found require a password. How do I skip this completely? I just seem to get UserSession.create to work.

  • Passenger problem: "no such file to load" -- /config/environment

    - by Mason Jones
    I've been researching this one and found references to similar problems here and there, but none of them has led to a solution yet. I've installed passenger (2.2.11) and nginx (0.7.64) and when I start things up and hit a Rails URL, I get an error page informing me of a load error: no such file to load -- /path/to/app/config/environment From what I've found online this appears to be some sort of a user/permissions error, but I've tried all the logical fixes: I've made sure that /config/environment.rb is not owned by root, but by a webapp user. I've tried setting passenger_default_user, I've tried setting passenger_user_switching off. I've even tried setting the nginx user, though that shouldn't matter much. I've gotten some differing results, but nothing's actually worked. I'm hoping someone may have the magical combination of settings and permissions for this. I may try backing down to an earlier version of Passenger, because I've never had this issue before; it's been a little while since I set up Passenger though. Thanks for any suggestions.

  • Rails - Why is my custom validation being triggered for only a build command.

    - by adam
    I have a sentence and correction model with a has_one and belongs_to relationship respectively. For some reason when I do def create @sentence = Sentence.find(params[:sentence_id]) @correction = @sentence.build_correction(params[:correction]) a custom validation I wrote for Correction is being called at the build_correction point. the validation is below class Correction < ActiveRecord::Base attr_accessible :text, :sentence_id, :user_id belongs_to :sentence belongs_to :user validate :correction_is_different_than_sentence def correction_is_different_than_sentence errors.add(:text, "can't be the same as the original sentence.") if (text == self.sentence.text) end the problem is for some reason on validation the correction object doesn't have the sentence id set (despite I used the build_correction method) and so it complains "you have nil object .... while executing nil.text" in the if clause in the validation above. So my question is why is the validation occuring for a build command, i thought it only triggers on a create or update. And why isnt the sentence_id getting set?

  • Reusing named_scope to define another named_scope

    - by Sergei Kozlov
    The problem essence as I see it One day, if I'm not mistaken, I have seen an example of reusing a named_scope to define another named_scope. Something like this (can't remember the exact syntax, but that's exactly my question): named_scope :billable, :conditions => ... named_scope :billable_by_tom, :conditions => { :billable => true, :user => User.find_by_name('Tom') } The question is: what is the exact syntax, if it's possible at all? I can't find it back, and Google was of no help either. Some explanations Why I actually want it, is that I'm using Searchlogic to define a complex search, which can result in an expression like this: Card.user_group_managers_salary_greater_than(100) But it's too long to be put everywhere. Because, as far as I know, Searchlogic simply defines named_scopes on the fly, I would like to set a named_scope on the Card class like this: named_scope from_big_guys, { user_group_managers_salary_greater_than(100) } - this is where I would use that long Searchlogic method inside my named_scope. But, again, what would be the syntax? Can't figure it out. Resume So, is named_scope nesting (and I do not mean chaining) actually possible?

  • Unusual RJS error

    - by rrb
    Hi, I am getting the following error in my RoR application: RJS error: TypeError: element is null Element.update("notice", "Comment Posted"); Element.update("allcomments", "\n\n\n \n\n waht now?\n\n \n\n \n\n \n\n asdfasdfa\n \n\n \n\n asdfasdf\n \n\n\n\n\n"); But when I hit the refresh button, I can see my partial updated. Here's my code: show_comments View: <table> <% comments.each do |my_comment| %> <tr> <td><%=h my_comment.comment%></td> </tr> <% end %> </table> show View: <div class="wrapper"> <div class="rescale"> <div class="img-main"> <%= image_tag @deal.photo.url %> </div> </div> <div class="description"> <p class ="description_content"> <%=h @deal.description %> </p> </div> </div> <p> <b>Category:</b> <%=h @deal.category %> </p> <p> <b>Base price:</b> <%=h @deal.base_price %> </p> <%#*<p>%> <%#*<b>Discount:</b>%> <%#=h @deal.discount %> <%#*</p>%> <%= link_to 'Edit', edit_deal_path(@deal) %> | <%= link_to 'Back', deals_path %> <p> <%= render :partial=>'deal_comments', :locals=>{ :comments=>Comment.new(:deal_id=>@deal.id)} %> </p> <div id="allcomments"> <%= render :partial=>'show_comments', :locals=>{ :comments=>Comment.find(@deal.comments)} %> </div> Controller: def create @comment = Comment.new(params[:comment]) render :update do |page| if @comment.save page.replace_html 'notice', 'Comment Posted' else page.replace_html 'notice', 'Something went wrong' end page.replace_html 'allcomments', :partial=> 'deals/show_comments', :locals=>{:comments=> @comment.deal.comments} end end def show_comments @deal = Deal.find(params[:deal_id]) render :partial=> "deals/show_comments", :locals=>{:comments=>@deal.comments} end end

  • Rails creating users, roles, and projects

    - by Bobby
    I am still fairly new to rails and activerecord, so please excuse any oversights. I have 3 models that I'm trying to tie together (and a 4th to actually do the tying) to create a permission scheme using user-defined roles. class User < ActiveRecord::Base has_many :user_projects has_many :projects, :through => :user_projects has_many :project_roles, :through => :user_projects end class Project < ActiveRecord::Base has_many :user_projects has_many :users, :through => :user_projects has_many :project_roles end class ProjectRole < ActiveRecord::Base belongs_to :projects belongs_to :user_projects end class UserProject < ActiveRecord::Base belongs_to :user belongs_to :project has_one :project_role attr_accessible :project_role_id end The project_roles model contains a user-defined role name, and booleans that define whether the given role has permissions for a specific task. I'm looking for an elegant solution to reference that from anywhere within the project piece of my application easily. I do already have a role system implemented for the entire application. What I'm really looking for though is that the users will be able to manage their own roles on a per-project basis. Every project gets setup with an immutable default admin role, and the project creator gets added upon project creation. Since the users are creating the roles, I would like to be able to pull a list of role names from the project and user models through association (for display purposes), but for testing access, I would like to simply reference them by what they have access to without having reference them by name. Perhaps something like this? def has_perm?(permission, user) # The permission that I'm testing user.current_project.project_roles.each do |role| if role.send(permission) # Not sure that's right... do_stuff end end end I think I'm in over my head on this one because I keep running in circles on how I can best implement this.

  • How to efficiently implement a blocking call with Rails, while letting the client wait for the reply

    - by Kyle Heironimus
    We have a web service written in Rails. The API is published and we cannot change it. Our app communicates with a remote web service that sometimes hangs or takes several seconds to reply. Client -> Our Web Service -> Remote Web Service Currently, if the remote web service hangs for 5 seconds, one of our rails processes on our web service also hangs with it, which is what we need to avoid. I've seen things such as mod-x-sendfile, modporter, and delayed jobs, but the best I can tell, they all assume the client is not waiting for an answer. Since the API is already established, we cannot tell the client "I'm attempting to do what you want, check back later for the answer." The best option we have come up with so far is to add a second, non-rails web server running eventmachine to process these particular calls. Is there a better way?

  • Hash default value not being used

    - by ba
    Today I tried the following snippets of code and I don't understand why I get different results between them. As far as I can understand they are the same. One uses the default value off Hash and the other snippet creates an empty array for the key before it'll be accessed. Anyone who understands what's going on? :) # Hash default if the key doesn't have a value set is an empty Array a = Hash.new([]) a[:key] << 2 # => [2] p a # => {} nil p a[:key] # => [2] # Explicitly add an array for all nodes before creating b = Hash.new b[:key] ||= [] b[:key] << 2 # => [2] p b # => {:key=>[2]}

  • paypal_adaptive gem in Rails: Dynamic Receiver "Population" (Chained Payments)

    - by Jmlevick
    Note: I didn't find a better title for this O.o Hello, Humm... Look, what I want to do is to have a Rails app where a visitor can click a button/link to make a "special" chained payment using Paypal; Currently I have a Users registration form that has one field for the user to enter his/her paypal account email, and as I saw here: http://marker.to/XGg9MR it is possible to specify the primary reciever and the secondary ones by adding such info in a controller action when using the paypal_adaptive gem in a rails app. The thing is, I don't want to hard code the secondary reciever as I need to specify a different secondary reciever from time to time, (being specific my primary reciever will always be the same, but depending on what button/link the visitor clicks, the secondary one is going to change) and I want that secondary reciever email to be the paypal e-mail account from one of the registered users when the visitor clicks on their specific button/link... My question is: Is it possible to create such enviroment functionality in my app using the current implementation of the paypal_adaptive gem? Could someone point me in the right direction on how to accomplish such thing? I'm still learning rails and also I'm really new in the paypal handling universe with this framework! XD P.S. Thanks! :)

  • How do I create a polymorphic model with a collection_select?

    - by muxe
    This are my models: class Speaker < ActiveRecord::Base belongs_to :session, :foreign_key => :session_id, :class_name => :Session belongs_to :speakable, :polymorphic => true end class Session < ActiveRecord::Base has_many :speakers accepts_nested_attributes_for :speakers end class Person < ActiveRecord::Base has_many :speakers, :as => :speakable end class Company < ActiveRecord::Base has_many :speakers, :as => :speakable end What I want to do now is something like this: app/views/sessions/edit.html.erb <% f.fields_for :speakers do |sf| %> <p> <%= sf.label :speaker %><br /> <%= sf.collection_select :speakable, Company.all + Person.all, :id, :full_name %> </p> <% end %> But it is not working because of the polymorphic assignment. How do I approach this problem? EDIT: The Error is: undefined method `base_class' for String:Class with params being: "speaker"=>{"speakable"=>"1063885469", "session_id"=>"1007692731"} The value passed to speakable is the id of the Speaker/Company. Yes, this is the value I specified the collection_select to return, but how can I manage to supply both values (speakable_id and speakable_type) ?

  • Can using Chronic impair your sense of time?

    - by Trip
    Haha.. I'm using Chronic to parse the time users add in the Calendar. Where the code works and implements the right time, the end result is that, IF a user adds a time, then it has no date, and because it has no date, it will not show in results. Any ideas? def set_dates unless self.natural_date.blank? || Chronic.parse(self.natural_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_date) self.date = nil self.time = Chronic.parse(self.natural_date) else self.date = Chronic.parse(self.natural_date).to_date self.time = nil end end unless self.natural_end_date.blank? || Chronic.parse(self.natural_end_date).blank? # check if we are dealing with a date or a date + time if time_provided?(self.natural_end_date) self.end_date = nil self.end_time = Chronic.parse(self.natural_end_date) else self.end_date = Chronic.parse(self.natural_end_date).to_date self.end_time = nil end end end Edit: Here is the time_provided? method: def time_provided?(natural_date_string) date_span = Chronic.parse(natural_date_string, :guess => false) (date_span.last - date_span.first).to_i == 1 end
