  • Operations inside Rails I18n locales' strings

    - by Cristobal Viedma
    Hi, I am trying to put operations inside the locales to adapt to different languages. For example, in English a billion is 1,000,000,000, however in Spanish a billion is 1,000,000,000,000 so I would like to be able to have the following: en: billion: "You have %{money} billions" es: billion: "Tienes %{money/1000.0} billones" In order to be able to write: I18n.t :billion, :money => whatever And be right for whatever language. However, it seems that I cannot put operations inside the locales' strings. Any hint on how should I be doing this? Maybe my approach is just wrong "philosophically" talking? Thanks all!

  • Refactoring Rails 3 Routes

    - by Martin
    Hello, I have this in my routes: get '/boutique/new' => 'stores#new', :as => :new_store, :constraints => { :id => /[a-z0-9_-]/ } post '/boutique' => 'stores#create', :as => :create_store, :constraints => { :id => /[a-z0-9_-]/ } get '/:shortname' => 'stores#show', :as => :store, :constraints => { :id => /[a-z0-9_-]/ } get '/:shortname/edit' => 'stores#edit', :as => :edit_store, :constraints => { :id => /[a-z0-9_-]/ } put '/:shortname' => 'stores#update', :as => :update_store, :constraints => { :id => /[a-z0-9_-]/ } delete '/:shortname' => 'stores#delete', :as => :destroy_store, :constraints => { :id => /[a-z0-9_-]/ } Is there a cleaner way to do the same? It doesn't look any elegant and even less if I add some more controls/actions to it. Thank you.

  • Where to put code snippets in Rails?

    - by Nik
    Hello all, I have this code snippets that generates a signature for POSTs. The detail of it is not important, but what I want to know is: since it is not a model-related chunk of code, it really can be use anywhere: in controllers, in models, in view helpers; even in views. So I am unsure where and, even bigger of a problem, how to activate the use of it once I place it in some location. Is it what those "require" statements are all about? That you can acquire some functionality through a "require" statement in the current file you are working on? Just so that we have an example to talk about, say, I have a little snippet of code that does cubing: def cube_it(num) num**3 end I know that I will be using it in various places across the application, so where should I put it? and when I do need to use it, how can I "summon" it? Thank You

  • Rails always include (join) on initialize

    - by Seth
    Hello, I have a User model as illustrated below: class User < ActiveRecord belongs_to :college belongs_to :class_level end I want to ALWAYS join with those other two tables returning one simplified User object. How do I accomplish this in my User model. I'm aware that I can do this in another model: class Foo < ActiveRecord has_many :users, :include => [:college, :class_level] end But I want to do this in my User model, so Foo.users will either be eager loaded OR be joined already. Is there a way to create an initialize this in the User model?

  • Deep relationships in Rails

    - by Neil Middleton
    I have some projects. Those projects have users through memberships. However, those users belong to companies. Question is, how do I find out which companies can access a project? Ideally I'd be able to do project.users.companies, but that won't work. Is there a nice, pleasant way of doing this?

  • Rails Active Record find(:all, :order => ) issue.

    - by CodingWithoutComments
    I seem to be unable to use :order_by for more than one column at a time. For example, I have a "Show" model with date and attending columns. If I run the following code: @shows = Show.find(:all, :order => "date") I get the following results: [#<Show id: 7, date: "2009-04-18", attending: 2>, #<Show id: 1, date: "2009-04-18", attending: 78>, #<Show id: 2, date: "2009-04-19", attending: 91>, #<Show id: 3, date: "2009-04-20", attending: 16>, #<Show id: 4, date: "2009-04-21", attending: 136>] If I run the following code: @shows = Show.find(:all, :order => "attending DESC") [#<Show id: 4, date: "2009-04-21", attending: 136>, #<Show id: 2, date: "2009-04-19", attending: 91>, #<Show id: 1, date: "2009-04-18", attending: 78>, #<Show id: 3, date: "2009-04-20", attending: 16>, #<Show id: 7, date: "2009-04-18", attending: 2>] But, if I run: @shows = Show.find(:all, :order => "date, attending DESC") OR @shows = Show.find(:all, :order => "date, attending ASC") OR @shows = Show.find(:all, :order => "date ASC, attending DESC") I get the same results as only sorting by date: [#<Show id: 7, date: "2009-04-18", attending: 2>, #<Show id: 1, date: "2009-04-18", attending: 78>, #<Show id: 2, date: "2009-04-19", attending: 91>, #<Show id: 3, date: "2009-04-20", attending: 16>, #<Show id: 4, date: "2009-04-21", attending: 136>] Where as, I want to get these results: [#<Show id: 1, date: "2009-04-18", attending: 78>, #<Show id: 7, date: "2009-04-18", attending: 2>, #<Show id: 2, date: "2009-04-19", attending: 91>, #<Show id: 3, date: "2009-04-20", attending: 16>, #<Show id: 4, date: "2009-04-21", attending: 136>] This is the query being generated from the logs: [4;35;1mUser Load (0.6ms)[0m [0mSELECT * FROM "users" WHERE ("users"."id" = 1) LIMIT 1[0m [4;36;1mShow Load (3.0ms)[0m [0;1mSELECT * FROM "shows" ORDER BY date ASC, attending DESC[0m [4;35;1mUser Load (0.6ms)[0m [0mSELECT * FROM "users" WHERE ("users"."id" = 1) [0m Finally, here is my model: create_table "shows", :force => true do |t| t.string "headliner" t.string "openers" t.string "venue" t.date "date" t.text "description" t.datetime "created_at" t.datetime "updated_at" t.decimal "price" t.time "showtime" t.integer "attending", :default => 0 t.string "time" end What am I missing? What am I doing wrong? UPDATE: Thanks for all your help, but it seems that all of you were stumped as much as I was. What solved the problem was actually switching databases. I switched from the default sqlite3 to mysql.

  • Rails 3 respond_with, route constraints and resources

    - by Intelekshual
    I'm building a versioned API, so I have the following nested controllers: ApiController < ApplicationController Api::V1Controller < ApiController Api::V1::EventsController < Api::V1Controller The API is accessed via a subdomain. I have the following routes: constraints(:subdomain => "api") do scope :module => 'api' do namespace :v1 do resources :events end end end This produces the type of URL I want (/v1/events). The problem I'm facing is when using responds_with in Api::V1::EventsController. Just doing something as simple as the below fails with the error too few arguments: def index @events = Event.all respond_with(@events) end I know respond_width is meant to be used with resources, but I'm not sure how the events resource should be accessed from the constrained, scoped, and namespaced route. I can output other things (such as current_user), just not an array of events. Help?

  • Problem with displaying usernames in my flash[:notice] - Agile Web Development With Rails - Chapter

    - by Lee
    I can't figure out what I'm doing wrong here. I can’t seem to get the #{@user.name} to work in my flash[:notice] Everything else works just fine I can add new users, but when I add a new user instead of saying “User John Doe was successfully created”, it says “User #{@user.name} was successfully created.” I'm at this point in the depot app: depot_p/app/controllers/users_controller.rb to work.

  • Adding a LIKE criteria to a Rails Conditions block

    - by Neil Middleton
    Consider the following code which is to be thrown at an AR find: conditions = [] conditions[:age] = params[:age] if params[:age].present? conditions[:gender] = params[:gender] if params[:gender].present? I need to add another condition which is a LIKE criteria on a 'profile' attribute. How can I do this, as obviously a LIKE is usually done via an array, not a hash key.

  • Rails: Serializing objects in a database?

    - by keruilin
    I'm looking for some general guidance on serializing objects in a database. What are serialized objects? What are some best-practice scenarios for serializing objects in a DB? What attributes do you use when creating the column in the DB so you can use a serialized object? How to save a serialized object? And how to access the serialized object and its attributes? (Using hashes?)

  • Rails nil can't be coerced into Float

    - by alex
    After adding items, attempting to view my cart leads me to this error: nil can't be coerced into Float with the math line in this method in my line_item model highlighted: def total_price product.price * quantity end line items create action def create product = Product.find(params[:product_id]) @line_item = @cart.add_product(product.id) @line_item.quantity = params[:quantity] view <div id= "text_field"><%= text_field_tag 'quantity' %> </div> <%= button_to 'Add to Cart', line_items_path(:product_id => product) %> This has held me back for a couple days. (I'm new). Thanks.

  • Rails creating and updating 2 model records simultaneously

    - by LearnRails
    I have 2 tables product and history product table id name type price location 1 abc electronics $200 aisle1 history table id product_id status 1 1 price changed from $200 to $180 Whenever the product price or location is updated by a user by hitting the update button, 1) the changes should be automatically be reflected in the history status column without the user having to enter that manually. if the price is updated from 200 to 180 then a new history row will be created with new id and the status column will say ' price changed from $200 to $180' if the location is updated from aisle1 to aisle 2 then status displays ' loc changed from ailse1 to aisle 2' I tried to @product = Product.new(params[:product]) @history= History.new(params[:history]) if @product.save @history.new(attributes) == I am not sure of whether this approach is correct I would really appreciate if someone could tell me how the history can be automatically updated in this case.

  • Minimizing calls to database in rails

    - by ming yeow
    Hi guys, i am familiar with memcached and eager loading, but neither seems to solve the problem i am facing. My main performance lag comes from hundreds of data retrieval calls from the database. The tricky thing is that I do not know which set of users i need to retrieve until i have several steps of computation. I can refactor my code, but i was wondering how you experts handle this situation? I think it should be a fairly common situation def newsfeed - find out which users i need - retrieve those users via DB - find out which events happened for these users - for each of those events - retrieve new set of users - find out which groups are relevant - for each of those groups - retrieve new set of users - etc, etc end

  • Rails 3 Order By Count on has_many :through

    - by goo
    I have an application where I can list Items and add tags to each Item. The models Items and Tags are associated like this: class Item < ActiveRecord::Base has_many :taggings has_many :tags, :through => :taggings end class Tagging < ActiveRecord::Base belongs_to :item belongs_to :tag end class Tag < ActiveRecord::Base has_many :taggings has_many :items, :through => :taggings end So, this many-to-many relationship allows me to set n tags for each Item, and the same tag can be used several times. I'd like to list all tags ordered by the number of items associated with this tag. More used tags, shows first. Less used, last. How can I do that? Regards.

  • undefined method `model_name' for NilClass:Class - Rails application

    - by user1270259
    So I have seen other articles here on stack about this and a lot of the time people are not doing @post = post.new. I read some where to use the plural...?? any ways I am getting this error on my discussion code: Discussion Controller class DiscussionsController < ApplicationController def index @discussion = Discussion.new @discussions = Discussion.all end def create @discussion = Discussion.create(params[:discussion]) if @discussion.save redirect_to tasks_path, :flash => {:success => 'Created a new discussion'} else redirect_to tasks_path, :flash => {:error => 'Failed to create a discussion'} end end end Discussion Form <%= form_for @discussion do |f| %> <p><%= f.label :title %> <%= f.text_field :title %></p> <p><%= f.label :content %> <%= f.text_area :content %></p> <% end %> Discussion Routes resources :discussions do resources :comments end Now as far as I know I am doing this right, because I have a task form set up essentially the same way - but I have looked at my code for hours and have googled and tried other examples and now i see this: undefined method `model_name' for NilClass:Class Extracted source (around line #1): 1: <%= form_for @discussion do |f| %> 2: 3: <p><%= f.label :title %> 4: <%= f.text_field :title %></p> Which should mean that I am missing something from my controller.....is it as asilly as a spelling mistake? .

  • Rails 4 testing bug?

    - by Jamato
    Situation: if we add two identic line items into a cart, we update line item quantity instead of adding a duplicate.In browser everything works fine but in unit testing section something fails because of an empty cycle in code. Which I wanted to use to update all prices. Why? Is that a unit test engine bug? LineItem.all and cart.line_items in process of testing produce two DIFFERENT structures. #<LineItem id: 980190964, product_id: 1, cart_id: 999, created_at: "2014-06-01 00:21:28", updated_at: "2014-06-01 00:21:28", quantity: 2, price: #<BigDecimal:ba0fb544,'0.4E1',9(27)>> #<LineItem id: 980190964, product_id: 1, cart_id: 999, created_at: "2014-06-01 00:21:28", updated_at: "2014-06-01 00:21:28", quantity: 1, price: #<BigDecimal:ba0d1b04,'0.4E1',9(27)>> cart.line_items guy did not update quantity Code itself (produces LineItem which is then saved in line_item_controller which calls this method) class Cart < ActiveRecord::Base has_many :line_items, dependent: :destroy def add_product(product_id) # LOOK THIS CYCLE BREAKS UNIT TEST, SRSLY, I MEAN IT line_items.each do |item| end current_item = line_items.find_by(product_id: product_id) fresh_price = Product.find_by(id: product_id).price if current_item current_item.quantity += 1 else current_item = line_items.build(product_id: product_id, price: fresh_price) end return current_item end ... Unit test code test "non-unique item added" do cart = Cart.new(:id => 999) line_item0 = cart.add_product(2) line_item0.save line_item1 = cart.add_product(1) line_item1.save assert_equal 2, cart.line_items.size #success line_item2 = cart.add_product(1) line_item2.save assert_equal 2, cart.line_items.size, "what?" assert cart.total_price > 15 #fail, prices are not enough, quantity of product1 = 1 #we get total price from quantity, it's a simple method in model end And once again: IT DOES WORK in browser as it should. Even with cycle. I feel so dumb right now...
