  • :confirm option in Rails being ignored.

    - by peehskcalba
    I've got a table of projects in my Rails app, each with a delete link, like so: <%= link_to "Delete", project, :confirm => "Are you sure?", :method => :delete %> However, the delete request is sent even if the user clicks "Cancel" on the dialog box. Any ideas on how to fix this?

  • How does Rails Plugin Storage work?

    - by Kevin
    Trying to figure out how to install rails plugins manually on windows so I have a few questions. What does the directory need to be named in vendor/plugins? Is it arbitrary or is it linked to something within the plugin config files or is that what you set in the environment.rb? Once I've copied the files to the correct directory, do I always need to run something inside like init.rb or is it good to go? What's the difference between 'require' and 'include'? Thanks!

  • Rails - Dynamic cookie domains using Rack

    - by Tim B.
    I'm fairly new to Rails and Rack, but this guy had a seemingly straightforward write-up about using Rack to implement dynamic session domain middleware. The code looks good to and I've implemented it here on my local machine, but I'm still not able to transcend top level domains on a single login. Here's the middleware code: class SetCookieDomain def initialize(app, default_domain) @app = app @default_domain = default_domain end def call(env) host = env["HTTP_HOST"].split(':').first env["rack.session.options"][:domain] = custom_domain?(host) ? ".#{host}" : "#{@default_domain}" @app.call(env) end def custom_domain?(host) domain = @default_domain.sub(/^\./, '') host !~ Regexp.new("#{domain}$", Regexp::IGNORECASE) end end And then in environment.db: config.load_paths += %W(#{RAILS_ROOT}/app/middlewares) Lastly in production.db (and development.db): config.middleware.use "SetCookieDomain", ".example.org" Any help is greatly appreciated. EDIT: I'm running Rails 2.3.3 and Rack 1.0

  • Rails: Added new Action in Controller, but there is no path?

    - by Newbie
    Hello! I try to do following: A user is on his profile page. Now he edits his profile. He klicks on update and the data is saved. Now I want to redirect the user to another kind of profile-edit-page. I did the following in my users_controller.rb: def update @user = User.find(params[:id]) respond_to do |format| if @user.update_attributes(params[:user]) flash[:notice] = 'User was successfully updated.' if(@user.team_id != nil) format.html { redirect_to(@user) } else format.html { redirect_to choose_team_path } end format.xml { head :ok } else format.html { render :action => "edit" } format.xml { render :xml => @user.errors, :status => :unprocessable_entity } end end end def choose_team @user = User.find(params[:id]) end I created a view: /users/choose_team.html.erb Now I get the following error: undefined local variable or method `choose_team_path' for #<UsersController:0x1f56650> So I added choose_team to my routes.rb: map.choose_team 'choose-team', :controller => 'users', :action => 'choose_team' Now, after submitting my first edit form, it redirects me to http://localhost:3000/choose-team and I get following error: Couldn't find User without an ID What I want: If a user has no team_id, he should be redirected to my choose_team.html.erb for choosing a team, else he should be redirected to his profile/show. How to do this?

  • Search by ID, no keyword. Tried using :conditions but no result ouput.

    - by Victor
    Using Thinking Sphinx, Rails 2.3.8. I don't have a keyword to search, but I wanna search by shop_id which is indexed. Here's my code: @country = Country.search '', { :with => {:shop_id => params[:shop_id]}, :group_by => 'trip_id', :group_function => :attr, :page => params[:page] } The one above works. But I thought the '' is rather redundant. So I replaced it with :conditions resulting as: @country = Country.search :conditions => { :with => {:shop_id => params[:shop_id]}, :group_by => 'trip_id', :group_function => :attr, :page => params[:page] } But then it gives 0 result. What is the correct code? Thanks.

  • Group and count in Rails

    - by alamodey
    I have this bit of code and I get an empty object. @results = PollRoles.find( :all, :select => 'option_id, count(*) count', :group => 'option_id', :conditions => ["poll_id = ?", @poll.id]) Is this the correct way of writing the query? I want a collection of records that have an option id and the number of times that option id is found in the PollRoles model. EDIT: This is how I''m iterating through the results: <% @results.each do |result| %> <% @option = Option.find_by_id(result.option_id) %> <%= @option.question %> <%= result.count %> <% end %>

  • using helper methods in a view in rails 3

    - by Frida777
    Hello everyone, there is something that is disturbing me a bit about rails 3. i am trying to upgrade my application from rails 2 to rails 3. i followed all the steps necessary to do and things were working well for me till now except one thing: i have a helper method that is defined differently in different helpers, for example it is defined in the application_helper in one way and the same method defined in a different way in the homepage_helper, and defined differently in another helper, let's say video_helper, in addition to that, it is used in a shared view that is used throughout the application, now if i am in the homepage, i want this function to get called from the homepage_helper and if i am in the video page, the function must be called from the video_helper, based on the concept of convention in rails, this worked perfectly in rails 2 but in rails 3, the function is always called from the last helper, alphabetically ordered, that is in the example, video_helper. How can i fix this? Kindly advice. Appreciate all the help.

  • Beginning with Datampper, Association question

    - by Ian
    I'm just diving into Datamapper (and Sinatra) and have a question about associations. Below are some models I have. This is what I want to implemented. I'm having an issue with Workoutitems and Workout. Workout will be managed separately, but Workoutitems has a single workout associated with each row. Workout - just a list of types of workouts (run, lift, situps, etc) Selected workout - this is the name of a set of workouts, along with notes by the user and trainer. It has a collection of N workoutitems Workoutitems - this takes a workout and a number of repetitions to it that go in the workout set. class Workout include DataMapper::Resource property :id, Serial #PK id property :name, String, :length=50,:required=true # workout name property :description, String, :length=255 #workout description end class Selectedworkout include DataMapper::Resource property :id, Serial property :name, String, :length=50, :required=true property :workout_time, String, :length=20 property :user_notes, String, :length=255 property :coach_notes, String, :length=255 has n, :workoutitems end class Workoutitem include DataMapper::Resource property :id, Serial property :reps, String, :length=50, :required=true belongs_to :selectedworkout end

  • [Rails] checkbox to update attribute

    - by Jeff
    [Updated a bit] I have a Task model that has a :completed boolean attribute. If I click on it I want it to execute the 'finish' method. The main problem is that I am displays a series of checkboxes in a list and subsequent checkboxes after the first one are ignored. The method is never called for the given task/checkbox combo. I have this chunk of code in my view: <% current_user.tasks.each do |t|%> <% if t.completed == false %> <%= check_box_tag :completed, true, checked = false %> <%= observe_field :completed, :url => { :controller => 'tasks', :action => :finish , :id => t.id }, :frequency => 0.25, :update => :completed, :with => true %> and my finish method looks like this: def finish @task = Task.find(params[:id]) new = {:completed => true} @task.update_attributes(new) render :update do |page| page.replace_html "taskListing", :partial => 'home/task_listing' end

  • :include and table aliasing

    - by dondo
    I'm suffering from a variant of the problem described here: ActiveRecord assigns table aliases for association joins fairly unpredictably. The first association to a given table keeps the table name. Further joins with associations to that table use aliases including the association names in the path... but it is common for app developers not to know about [other] joins at coding time. In my case I'm being bitten by a toxic mix of has_many and :include. Many tables in my schema have a state column, and the has_many wants to specify conditions on that column: has_many :foo, :conditions => {:state => 1}. However, since the state column appears in many tables, I disambiguate by explicitly specifying the table name: has_many :foo, :conditions => "this_table.state = 1". This has worked fine until now, when for efficiency I want to add an :include to preload a fairly deep tree of data. This causes the table to be aliased inconsistently in different code paths. My reading of the tickets referenced above is that this problem is not and will not be fixed in Rails 2.x. However, I don't see any way to apply the suggested workaround (to specify the aliased table name explicitly in the query). I'm happy to specify the table alias explicitly in the has_many statement, but I don't see any way to do so. As such, the workaround doesn't appear applicable to this situation (nor, I presume, in many 'named_scope' scenarios). Is there a viable workaround?

  • How to use Many to Many in Rails?

    - by Newbie
    Hello! In my project, I have users and quests. One User can join multiple quests and one quest can have multiple users. So I created a table called questing, containing the user_id and the quest_id. In my user.rb I did following: require 'digest/sha1' class User < ActiveRecord::Base has_many :questings has_many :quests ,:through =>:questings ... My Quest.rb: class Quest < ActiveRecord::Base has_many :questings has_many :users ,:through =>:questings ... My Questing.rb: class Questing < ActiveRecord::Base belongs_to :quest belongs_to :user end Now I want to create a link or button on my /quests/show.html.erb, calling an action in my controller, which will create the relationship between user and quest. So, in my quest_controller I did: def join_quest @quest = Quest.find(params[:id]) puts '************************' puts 'join quest:' + @quest.id puts '************************' respond_to do |format| format.html { redirect_to(@quest) } format.xml { head :ok } end end and in my show.html.erb I did: <%= link_to 'join this quest!!!', :action => :join_quest %> Now, clicking on this link will cause an error like: Couldn't find Quest with ID=join_quest and the url points to */quests/join_quest* instead of */quests/1/join_quest* Now my questions: Is my quests_controller the right place for my join_quest action, or should I move it to my users_controller? Why do I get this error? How to solve it? What do I have to write in my join_quest action for saving the relationship? On my /users/show.html.erb I want to output all quests the user joined. How to do this? I have to get all this quests from my relationship table, right? How? I hope you can help me! THX!
