  • Compare a DateTime to the current date

    - by looloobs
    Hi I am trying to use a condition on events when the start_at DateTime is equal to or greater than Today's date. I want to list upcoming events, but clearly they are not upcoming if they have already passed. I have: @appointments = Event.find(:all, :conditions => ['move_id = ? AND start_at = ?', @move.id, Date.today]) I think I may be comparing apples and oranges here. It doesn't throw and error, just doesn't do what it is supposed to. Help! Thanks in advance.

  • Rails botches the SQL on a complex save

    - by Dan B
    Hi, I am doing something seemingly pretty easy, but Rails is messing up the SQL. I could just execute my own SQL, but the framework should be able to handle this. Here is the save I am trying to perform: w = WhipSenVote.find(:first, :conditions => ["whip_bill_id = ? AND whip_sen_id = ?", bill_id, k]) w.votes_no = w.votes_no - 1 w.save My generated SQL looks like this: SELECT * FROM "whip_sen_votes" WHERE (whip_bill_id = E'1' AND whip_sen_id = 7) LIMIT 1 And then: UPDATE "whip_sen_votes" SET "votes_yes" = 14, "updated_at" = '2009-11-13 19:55:54.807000' WHERE "id" = 15 The first select statement is correct, but as you can see, the Update SQL statement is pretty wrong, though the votes_yes value is correct. Any ideas? Thanks!

  • How to clone a model's attributes easily?

    - by Zabba
    I have these models: class Address < ActiveRecord::Base belongs_to :event attr_accessible :street, :city validates :street, :city, :presence => true end class Event < ActiveRecord::Base has_one :address accepts_nested_attributes_for :address end If I do the below assignment in the Events create action and save the event I get an error: #Use the current user's address for the event @event.address_attributes = current_user.address.attributes #Error occurs at the above mentioned line ActiveRecord::RecordNotFound (Couldn't find Address with ID=1 for Event with ID=) I think what's happening is that all the address's attributes (including the primary key) is getting assigned in the @event.address_attributes = line. But all I really want is the "real data" (street, city), not the primary keys or created_at etc to get copied over. I suppose I could write a small method to do this sort of selective copy but I can't help but feel there must be some built-in method for this? What's the best/right way to do this?

  • Get data from database with two conditions in one list

    - by Kreeki
    Hi coders out there, I'm new to this. I have a (sqlite3, but with ActiveRecord it doesn't matter) table called Messages and a model called Message. I want to find all messages in database that have user_id or reciever_id equal to the object user and his attribute id (for short user.id). I know it's probably just one simple line of code, but I wanna do it the right "rails" way and I don't have much experience with this. I'm using Rails 3. Thanks for any help. Cheers

  • confusion using rjs for a link_to_remote

    - by odpogn
    My application layout contains a navigation div, and a content div constructed as a partial. I want to use ajax so that whenever a person clicks on a link in the navigation div, the contents of that page renders in the content div without a refresh. I'm confused on how to properly do this... any help for a rails noob??? thanks in advance~ application.html.erb <body> <div id="container"> <%= render 'layouts/header' %> <%= render 'layouts/content'%> <%= render 'layouts/footer' %> </div> </body> _header.html.erb <%= link_to_remote "Home", :url => { :controller => "pages", :action => "home" } %> _content.html.erb <div id="content"> <%= yield %> </div> pages_controller.rb def home @title = "Home" respond_to do |format| format.js end end home.rjs page.replace_html :container, :partial => 'layouts/content'

  • Rails Nested Attributes Doesn't Insert ID Correctly

    - by MunkiPhD
    I'm attempting to edit a model's nested attributes, much as outline here, replicated here: <%= form_for @person do |person_form| %> <%= person_form.text_field :name %> <% for address in @person.addresses %> <%= person_form.fields_for address, :index => address do |address_form|%> <%= address_form.text_field :city %> <% end %> <% end %> <% end %> In my code, I have the following: <%= form_for(@meal) do |f| %> <!-- some other stuff that's irrelevant... --> <% for subitem in @meal.meal_line_items %> <%= f.fields_for subitem, :index => subitem do |line_item_form| %> <%= line_item_form.label :servings %><br/> <%= line_item_form.text_field :servings %><br/> <%= line_item_form.label :food_id %><br/> <%= line_item_form.text_field :food_id %><br/> <% end %> <% end %> <%= f.submit %> <% end %> This works great, except, when I look at the HTML, it's creating the inputs that look like the following, failing to input the correct id and instead placing the memory representation(?) of the model: <input type="text" value="2" size="30" name="meal[meal_line_item][#<MealLineItem:0x00000005c5d618>][servings]" id="meal_meal_line_item_#<MealLineItem:0x00000005c5d618>_servings">

  • Rails 3 ActiveRecord group_by sort by count

    - by Craig
    The following view code generates a series of links with totals (as expected): <% @jobs.group_by(&:employer_name).sort.each do |employer, jobs| %> <%= link_to employer, jobs_path() %> <%= "(#{jobs.length})" %> <% end %> However, when I refactor the view's code and move the logic to a helper, the code doesn't work as expect. view: <%= employer_filter(@jobs_clone) %> helper: def employer_filter(jobs) jobs.group_by(&:employer_name).sort.each do |employer,jobs| link_to employer, jobs_path() end end The following output is generated: <Job:0x10342e628>#<Job:0x10342e588>#<Job:0x10342e2e0>Employer A#<Job:0x10342e1c8>Employer B#<Job:0x10342e0d8>Employer C#<Job:0x10342ded0>Employer D# What am I not understanding? At first blush, the code seems to be equivalent.

  • NoMethodError using Memcached Sinatra-style

    - by sevennineteen
    I've just installed Memcached on my Mac and updated my Sinatra app configuration as described in Heroku's documentation, but I'm getting a NoMethodError when trying to use the hash-based syntax they specify: >> CACHE['color'] = 'blue' >> CACHE['color'] Using explicit get and set methods as below seems to work fine. >> CACHE.set('color', 'blue') >> CACHE.get('color') If necessary I can use the latter syntax, but the former seems more elegant. I haven't tested this on Heroku's environment since I'd like whatever implementation I use to work on my local environment as well. Thanks!

  • link_to syntax with rails3 (link_to_remote) and basic javascript not working in a rails3 app?

    - by z3cko
    i am wondering if the basic link_to syntax is completely broken in current rails3 master or if i am doing some wrong syntax here. = link_to "name", nil, :onlick => "alert('Hello world!');" should actually produce an alert on click. very simple. does not work on my rails3 project! (also no error output!) any ideas? for the general link_to syntax i could not find an example where i could combine a link_to_remote with a confirmation, remote and html class (see my try below) = link_to "delete", {:action => "destroy", :remote => true, :method => :delete, :confirm => "#{a.title} wirklich L&ouml;schen?" }, :class => "trash" even the rails3 api does not help me here: http://rails3api.s3.amazonaws.com/index.html help!

  • Support for multiple domains/subdomains in Rails

    - by thefactor
    I have a Rails app that has a similar setup to Tumblr, that is, you can have either: (1) Subdomain hosting (your-username.myapp.com) (2) Domain hosting (your-username.com) Both would forward to a personalized website for that user, created with my application. How can I accomplish this in Rails? I have been able to get (1) working with subdomain-fu, but I'm not sure how to get (2) working. Any pointers (plugins, gems, tutorials), etc. would be greatly helpful, I can't seem to find any. Thanks!

  • One model and Many edit views

    - by user179438
    Hi, I have a model I named User, and I want use two different Views to edit it: the usual edit view and another view I called edit_profile. I had no problem in creating routing, controller and views: I added edit_profile and update_profile views, and I added on routes.rb the line: map.resources :users ,:member => {:edit_profile => :get, :update_profile => :put} The problem is: when I submit the form in edit_profile and some error occur in some input fields, rails reload the edit_path page instead of edit_profile_path page ! This is the form on edit_profile.html.erb form_for(:user, @user, :url => {:action => :update_profile}, :html => { :method => :put} ) do |f| = f.text_field :description = f.text_area :description = f.error_message_on :description .... .... = f.submit 'Update profile' After clicking Update profile, if input errors occur I want to show edit_profile view instead of edit view Do You have some ideas ? many thanks

  • Rails Collection_select names

    - by Jack
    Hi, I am creating a Rails app and have added a form: <div class="field"> <%= f.label :title %><br /> <%= f.text_field :title %> </div> <div class="field"> <%= f.label :client_id %><br /> <%= collection_select(:project, :client_id, Client.all, :id, :contact_name, {:prompt => "Select a Client"}) %> </div> This currently displays the contact_name of the client. Is it possible to have it display a list of contact_names concatenated with the client_id? If so, how would I do this? Cheers

  • Rails attribute alias

    - by Dr1Ku
    Hi, I was just wondering if it's possible to "rename" an association in Rails. Let's assume : # An ActiveRecord Class named SomeModelASubModel (some_model_a_sub_model.rb) class SomeModelASubModel < ActiveRecord::Base has_many :some_model_a_sub_model_items end # An ActiveRecord Class named SomeModelASubModelItem (some_model_a_sub_model_item.rb) class SomeModelASubModelItem < ActiveRecord::Base belongs_to :some_model_a_sub_model end At this point, calling some_model.items, where some_model is an instance of the SomeModelASubModel Class would trigger an undefined method error. What is the best practice for making this happen though, e.g. : # With a method_alias or something, would it be possible to : some_model = SomeModelASubModel.first # for instance items = some_model.items # For the reason stated, this doesn't work, one has to call : items = some_model.some_model_a_sub_model_items Is such a shorthand possible ? Thank you in advance !

    I've came into a problem while working with AR and polymorphic, here's the description, class Base < ActiveRecord::Base; end class Subscription < Base set_table_name :subscriptions has_many :posts, :as => :subscriptable end class Post < ActiveRecord::Base belongs_to :subscriptable, :polymorphic => true end in the console, >> s = Subscription.create(:name => 'test') >> s.posts.create(:name => 'foo', :body => 'bar') and it created a Post like: #<Post id: 1, name: "foo", body: "bar", subscriptable_type: "Base", subscriptable_id: 1, created_at: "2010-05-10 12:30:10", updated_at: "2010-05-10 12:30:10"> the subscriptable_type is Base but Subscription, anybody can give me a hand on this?
