  • How to create contexts in shoulda macros

    - by Honza
    Asking this question again with smaller code sample: # this is a dummy shoulda macro that creates a context def self.macro_context context "macro" do yield end end # i am expecting this test to fail within the macro context context "some context" do macro_context do should "test" do fail end end end So what I would expect is to see: 1) Error: test: some context macro context should test. (TestClassName) But I am getting only this: So what I would expect is to see: 1) Error: test: some context should test. (TestClassName) Any idea what am I doing wrong?

  • "Can't mass-assign protected attributes" with nested protected models

    - by JohnnyFive
    I'm having a hell of a time trying to get this nested model working. I've tried all manner of pluralization/singular, removing the attr_accessible altogether, and who knows what else. restaurant.rb: # == RESTAURANT MODEL # # Table name: restaurants # # id :integer not null, primary key # name :string(255) # created_at :datetime not null # updated_at :datetime not null # class Restaurant < ActiveRecord::Base attr_accessible :name, :job_attributes has_many :jobs has_many :users, :through => :jobs has_many :positions accepts_nested_attributes_for :jobs, :allow_destroy => true validates :name, presence: true end job.rb: # == JOB MODEL # # Table name: jobs # # id :integer not null, primary key # restaurant_id :integer # shortname :string(255) # user_id :integer # created_at :datetime not null # updated_at :datetime not null # class Job < ActiveRecord::Base attr_accessible :restaurant_id, :shortname, :user_id belongs_to :user belongs_to :restaurant has_many :shifts validates :name, presence: false end restaurants_controller.rb: class RestaurantsController < ApplicationController before_filter :logged_in, only: [:new_restaurant] def new @restaurant = Restaurant.new @user = current_user end def create @restaurant = Restaurant.new(params[:restaurant]) if @restaurant.save flash[:success] = "Restaurant created." redirect_to welcome_path end end end new.html.erb: <% provide(:title, 'Restaurant') %> <%= form_for @restaurant do |f| %> <%= render 'shared/error_messages' %> <%= f.label "Restaurant Name" %> <%= f.text_field :name %> <%= f.fields_for :job do |child_f| %> <%= child_f.label "Nickname" %> <%= child_f.text_field :shortname %> <% end %> <%= f.submit "Done", class: "btn btn-large btn-primary" %> <% end %> Output Parameters: {"utf8"=>"?", "authenticity_token"=>"DjYvwkJeUhO06ds7bqshHsctS1M/Dth08rLlP2yQ7O0=", "restaurant"=>{"name"=>"The Pink Door", "job"=>{"shortname"=>"PD"}}, "commit"=>"Done"} The error i'm receiving is: ActiveModel::MassAssignmentSecurity::Error in RestaurantsController#create Cant mass-assign protected attributes: job Rails.root: /home/johnnyfive/Dropbox/Projects/sa Application Trace | Framework Trace | Full Trace app/controllers/restaurants_controller.rb:11:in `new' app/controllers/restaurants_controller.rb:11:in `create' Anyone have ANY clue how to get this to work?

  • rails semi-complex STI with ancestry data model planning the routes and controllers

    - by ere
    I'm trying to figure out the best way to manage my controller(s) and models for a particular use case. I'm building a review system where a User may build a review of several distinct types with a Polymorphic Reviewable. Country (has_many reviews & cities) Subdivision/State (optional, sometimes it doesnt exist, also reviewable, has_many cities) City (has places & review) Burrow (optional, also reviewable ex: Brooklyn) Neighborhood (optional & reviewable, ex: williamsburg) Place (belongs to city) I'm also wondering about adding more complexity. I also want to include subdivisions occasionally... ie for the US, I might add Texas or for Germany, Baveria and have it be reviewable as well but not every country has regions and even those that do might never be reviewed. So it's not at all strict. I would like it to as simple and flexible as possible. It'd kinda be nice if the user could just land on one form and select either a city or a country, and then drill down using data from say Foursquare to find a particular place in a city and make a review. I'm really not sure which route I should take? For example, what happens if I have a Country, and a City... and then I decide to add a Burrow? Could I give places tags (ie Williamsburg, Brooklyn) belong_to NY City and the tags belong to NY? Tags are more flexible and optionally explain what areas they might be in, the tags belong to a city, but also have places and be reviewable? So I'm looking for suggestions for anyone who's done something related. Using Rails 3.2, and mongoid.

  • Rails: How do I unserialize from database?

    - by Macint
    Hello, I am currently trying to save information for an invoice/bill. On the invoice I want to show what the total price is made up of. The procedures & items, their price and the qty. So in the end I hope to get it to look like this: Consult [date] [total_price] Procedure_name [price] [qty] Procedure_name [price] [qty] Consult [date] [total_price] Procedure_name [price] [qty] etc... All this information is available through the database but i want to save the information as a separate copy. That way if the user changes the price of some procedures the invoice information is still correct. I thought i'd do this by serializing and save the data to a column (consult_data) in the Invoice table. My Model: class Invoice < ActiveRecord::Base ...stuff... serialize :consult_data ... end This is what I get from the form (1 consult and 3 procedures): {"commit"=>"Save draft", "authenticity_token"=>"MZ1OiOCtj/BOu73eVVkolZBWoN8Fy1skHqKgih7Sbzw=", "id"=>"113", "consults"=>[{"consult_date"=>"2010-02-20", "consult_problem"=>"ABC", "procedures"=>[{"name"=>"asdasdasd", "price"=>"2.0", "qty"=>"1"}, {"name"=>"AAAnd another one", "price"=>"45.0", "qty"=>"4"}, {"name"=>"asdasdasd", "price"=>"2.0", "qty"=>"1"}], "consult_id"=>"1"}]} My save action: def add_to_invoice @invoice = @current_practice.invoices.find_by_id(params[:id]) @invoice.consult_data=params[:consults] if @invoice.save render :text => "I think it worked" else render :text => "I don't think it worked'" end end It does save to the database and if I look at the entry in the console I can see that it is all there: consult_data: "--- \n- !map:HashWithIndifferentAccess \n consult_da..." (---The question---) But I can't seam to get back my data. I tried defining a variable to the consult_data attribute and then doing "variable.consult_problem" or "variable[:consult_problem]" (also tried looping) but it only throws no-method-errors back at me. How do I unserialize the data from the database and turn it back into hash that i can use? Thank you very much for any help!

  • nested form & habtm

    - by brewster
    so i am trying to save to a join table in a habtm relationship, but i am having problems. from my view, i pass in a group id with: = link_to "Create New User", new_user_url(:group => 1) User model (user.rb) class User < ActiveRecord::Base has_and_belongs_to_many :user_groups accepts_nested_attributes_for :user_groups end UserGroups model (user_groups.rb) class UserGroup < ActiveRecord::Base has_and_belongs_to_many :users end users_controller.rb def new @user = User.new(:user_group_ids => params[:group]) end in the new user view, i have access to the User.user_groups object, however when i submit the form, not only does it not save into my join table (user_groups_users), but the object is no longer there. all the other objects & attributes of my User object are persistent except for the user group. i just started learning rails, so maybe i am missing something conceptually here, but i have been really struggling with this.

  • Combining Two Models in Rails for a Form

    - by matsko
    Hey Guys. I'm very new with rails and I've been building a CMS application backend. All is going well, but I would like to know if this is possible? Basically I have two models: @page { id, name, number } @extended_page { id, page_id, description, image } The idea is that there are bunch of pages but NOT ALL pages have extended_content. In the event that there is a page with extended content then I want to be able to have a form that allows for editing both of them. In the controller: @page = Page.find(params[:id]) @extended= Extended.find(:first, :conditions = ["page_id = ?",@page.id]) @combined = ... #merge the two somehow So in the view: <%- form_for @combined do |f| % <%= f.label :name % <%= f.text_field :name % ... <%= f.label :description % <%= f.text_field :description % <%- end This way in the controller, there only has to be one model that will be updated (which will update to both). Is this possible?

  • What is the most elegant way to validate the presence of ONLY one out of two attributes using Rails?

    - by marcgg
    class Followup < ActiveRecord::Base belongs_to :post belongs_to :comment end This model needs to only have either a post or a comment, but only one of the two. Here's the rspec for what I'm trying to do: it "should be impossible to have both a comment and a post" do followup = Followup.make followup.comment = Comment.make followup.should be_valid followup.post = Post.make followup.should_not be_valid end I can see a bunch of ways of doing this, but what would be the most elegant way of doing this?

  • Facebooker Session is not created when config.cache_classes = true

    - by Michal
    I am using Facebooker (along with devise & devise_facebook_connectable). The problem is that user can't sign in with Facebook Connect in production environment unless I set config.cache_classes to false (which I don't want to do in production obviously). When cache_classes = true, Facebooker::Session.current is nil. Trying to set it manually creates other problems, so I assume it's not the solution. Using Rails 2.3.8 (tried on 2.3.5 too) and Facebooker 1.0.70 (tries on 1.0.69 too) and passenger 2.2.11. Any hints?

  • CarrierWave and nested forms saving empty image object if photo :title is included in form

    - by Wasabi Developer
    I'm after some advice in regards to handling nested form data and I would be ever so grateful for any insights. The trouble is I'm not 100% sure why I require the following code in my model accepts_nested_attributes_for :holiday_image, allow_destroy: true, :reject_if => lambda { |a| a[:title].blank? } If I don't understand why I require to tact on on my accepts_nested_attributes_for association: :reject_if => lambda { |a| a[:title].blank? } If I remove this :reject_if lambda, it will save a blank holiday photo object in the database. I presume because it takes the :title field from the form as an empty string? I guess my question is, am I doing this right or is there a better way of this this within nested forms if I want to extend my HolidayImage model to include more strings like description, notes? Sorry If I can't be more succinct. My simple holiday app. # holiday.rb class Holiday < ActiveRecord::Base has_many :holiday_image accepts_nested_attributes_for :holiday_image, allow_destroy: true, :reject_if => lambda { |a| a[:title].blank? } attr_accessible :name, :content, :holiday_image_attributes end I'm using CarrierWave for image uploads. # holiday_image.rb class HolidayImage < ActiveRecord::Base belongs_to :holiday attr_accessible :holiday_id, :image, :title mount_uploader :image, ImageUploader end Inside my _form partial there is a field_for block <h3>Photo gallery</h3> <%= f.fields_for :holiday_image do |holiday_image| %> <% if holiday_image.object.new_record? %> <%= holiday_image.label :title, "Image Title" %> <%= holiday_image.text_field :title %> <%= holiday_image.file_field :image %> <% else %> Title: <%= holiday_image.object.title %> <%= image_tag(holiday_image.object.image.url(:thumb)) %> Tick to delete: <%= holiday_image.check_box :_destroy %> <% end %> Thanks again for your patience.

  • Is there a Rails authentication library which separates users from login methods?

    - by Gareth
    In my mental model of authentication, a user should be distinct from the way they log in. So for example, a User could have an associated EmailLogin (with an email/password), or they could have many (or none). Similarly they could have 0..* associated OpenIDLogin credentials. Are there any existing authentication libraries for Rails which use this method? Alternatively, is this a really terrible idea?

  • Dynamic "OR" conditions in Rails 3

    - by Ryan Foster
    I am working on a carpool application where people can search for lifts. They should be able to select the city from which they would liked to be picked up and choose a radius which will then add the cities in range to the query. However the way it is so far is that i can only chain a bunch of "AND" conditions together where it would be right to say "WHERE start_city = city_from OR start_city = a_city_in_range OR start_city = another_city_in_range" Does anyone know how to achive this? Thanks very much in advance. class Search < ActiveRecord::Base def find_lifts scope = Lift.where('city_from_id = ?', self.city_from) #returns id of cities which are in range of given radius @cities_in_range_from = City.location_ids_in_range(self.city_from, self.radius_from) #adds where condition based on cities in range for city in @cities_in_range_from scope = scope.where('city_from_id = ?', city) #something like scope.or('city_from_id = ?', city) would be nice.. end end

  • Get number of times in loop over Hash object

    - by Matt Huggins
    I have an object of type Hash that I want to loop over via hash.each do |key, value|. I would like to get the number of times I've been through the loop starting at 1. Is there a method similar to each that provides this (while still providing the hash key/value data), or do I need to create another counter variable to increment within the loop?

  • Why is RSpec so slow under Rails?

    - by Adrian Dunston
    Whenever I run rspec tests for my Rails application it takes forever and a day of overhead before it actually starts running tests. Why is rspec so slow? Is there a way to speed up Rails' initial load or single out the part of my Rails app I need (e.g. ActiveRecord stuff only) so it doesn't load absolutely everything to run a few tests?

  • paperclip overwrites / resets S3 permissions for non-bucket-owners

    - by adriandz
    I have opened this as an issue on Github (http://github.com/thoughtbot/paperclip/issues/issue/225) but on the chance that I'm just doing this wrong, I thought I'd also ask about it here. If someone can tell me where I'm going wrong, I can close the issue and save the Paperclip guys some trouble. Issue: When using S3 for storage, and you wish your bucket to allow access to other users to whom you have granted access, Paperclip appears to overwrite the permissions on the bucket, removing access to these users. Process for duplication: Create a bucket in S3 and set up a Rails app with Paperclip to use this bucket for storage Add a user (for example, [email protected], the user for the video encoding service Zencoder) to the bucket, and grant this user List and Read/Write permissions. Upload a file. Refresh the permissions. The user you added will be gone. As well, a user "Everyone" with read permissions will have been added. The end result is that you cannot, so far as I can tell, retain desired permissions on your bucket when using Paperclip and S3. Can anyone help?

  • How do you deal with the conflict between ActiveSupport::JSON and the JSON gem?

    - by Luke Francl
    I am stumped with this problem. ActiveSupport::JSON defines to_json on various core objects and so does the JSON gem. However, the implementation is not the same -- the ActiveSupport version takes arguments and the JSON gem version doesn't. I installed a gem that required the JSON gem and my app broke. The issue is that I'm using to_json in a controller that returns a list of objects, but I want to control which attributes are returned. When code anywhere in my system does require 'json' I get this error message: TypeError: wrong argument type Hash (expected Data) I tried a couple of things that I read online to fix it, but nothing worked. I ended up re-writing the gem to use ActiveSupport::JSON.decode instead of JSON.parse. This works but it's not sustainable...I can't be forking gems every time I want to use a gem that requires the JSON gem. Update: The best solution of this problem is to upgrade to Rails 2.3 or higher, which fixed it.

  • Loading a page into memory in Rails

    - by titaniumdecoy
    My rails app produces XML when I load /reports/generate_report.xml. On a separate page, I want to read this XML into a variable and save it to the database. How can I do this? Can I somehow stream the response from the /reports/generate_report.xml URI into a variable? Or is there a better way to do it since the XML is produced by the same web app?

  • Ignoring extra keys in a hash passed in to create

    - by denniss
    Does rails provide a way to ignore extra keys that are passed in to create. Supposed User has two attributes, first_name and last_name. When I do User.create({ :first_name => "first", :last_name => "last", :age => 10}) that line gives me an UknonwnAttributeError. Well, that makes sense, it happens cause age is not one of the attributes. But is there a way to just ignore key-value pair that is not one of the attributes for User?
