  • How to create picture slideshows in a rails project? Flash or otherwise

    - by Janak
    In a rails project how would I create a picture slideshow? It could be generated as flash or use prototype or something else. I just want a series of images (as a sub-part of a web page, not be the whole page) to fade into each other, and to advance manually if clicked. It would be nice if I could do things like slowly zoom into the images I imagine there must be a plugin or something to handle this?

  • Rails: Creating subfolders in model?

    - by keruilin
    I'm going to have a ton of subclasses, so want to organize them under a subfolder called stream. I added the following line to the environment.rb so that all classes in the subfolder would be loaded: Rails::Initializer.run do |config| ... config.load_paths += Dir["#{RAILS_ROOT}/app/models/*"].find_all { |f| File.stat(f).directory? } ... end I thought this would solve the issue in which by convention the model class is namespaced into an according module. However, when I try to call one of the classes called stream in the stream folder, I get the following error: NoMethodError: undefined method `new' for Stream:Module from (irb):28 from /usr/local/bin/irb:12:in `<main>' Here's the model for the parent and one child: class Stream end class EventStream < Stream end Any idea what the issue is?

  • Using Cucumber or RSpec+Selenium to create end user documentation?

    - by carolclarinet
    Has anyone tried creating end user (potentially online, potentially to be printed) help/documentation out of your cucumber scenarios? Or taken screenshots for use in documentation using RSpec and Selenium RC's ability to do so? For Cucumber, I'm imagining something like: Scenario: If you want to add a link Given I am on the edit blog post page When I press the "add link" button And I type in a link URL "http://stackoverflow.com" And I click "OK" Then the blog post should have 1 link Translating to the documentation: If you want to add a link, go to the edit blog post page. Press the "add link" button and type a URL, like "http://stackoverflow.com", into the link URL field. Click "OK". Would it be worth my time to try and, for one, write something to parse my Cucumber features into documentation, and two, to write/structure my Cucumber features in such a way as to create good documentation? Would the resulting documentation end up sounding really boring without much variation in the structure? Is there anything else out there like this idea? Doxygen looks like it's more for code documentation than end-user documentation. What about automatically taking screenshots? This seems like a more fruitful path-- just reuse the code that takes a screenshot when an RSpec test fails and have it take one in prescribed situations. Is there a better way to do this?

  • How to allow devise users to edit their profil?

    - by user1704926
    I have a namespace called "backend" which is protected by Devise. I would like now to allow users to edit their profil. So I created a users_controller in Backend. Here's the users_controllercode : class Backend::UsersController < ApplicationController layout 'admin' before_filter :authenticate_user! def index @users = Backend::User.all respond_to do |format| format.html # index.html.erb format.json { render json: @users } end end def show @user = Backend::User.find(params[:id]) respond_to do |format| format.html # show.html.erb format.json { render json: @user } end end def edit @user = Backend::User.find(params[:id]) end def update @user = Backend::User.find(params[:id]) respond_to do |format| if @user.update_attributes(params[:user]) format.html { redirect_to @user, notice: 'Article was successfully updated.' } format.json { head :no_content } else format.html { render action: "edit" } format.json { render json: @user.errors, status: :unprocessable_entity } end end end end When I go on backend_users_path there is a list of all the users. I would like to permit to edit only his own profil. So I go on the Edit page : <%= link_to "Edit", edit_backend_user_path(backend_user.id) %> . Here's the Edit page code : <%= simple_form_for @user do |f| %> <div><%= f.label :email %><br /> <%= f.input :email, :autofocus => true %></div> <div><%= f.submit "Update" %></div> <% end %> And there is my problem : when I try to modify the email address, nothing happen. The update fails. How can I do this ? I'm quite lost. Thanks by advance.

  • SEO Friendly URLs where the phrase used may change in Rails

    - by Newy
    Say I have http://www.mysite.com/I-Like-Cheeseburgers and I want that to point to Item with id 3. Sometime later, I change the name of the item, and now its http://www.mysite.com/I-Like-Hamburgers (and perhaps many more times). I want all these URLs to remain pointing to Item 3. Is it efficient to simply keep a table of [strings,item_ids] and do a lookup on this? Is there a better way?

  • How to implement "short" nested vanity urls in rails?

    - by UnSandpiper
    I understand how to create a vanity URL in Rails in order to translate http://mysite.com/forum/1 into http://mysite.com/some-forum-name But I'd like to take it a step further and get the following working (if it is possible at all): Instead of: http://mysite.com/forum/1/board/99/thread/321 I'd like in the first step to get to something like this: http://mysite.com/1/99/321 and ultimately have it like http://mysite.com/some-forum-name/some-board-name/this-is-the-thread-subject. Is this possible?

  • Rails Rspec testing not saving a transactional model

    - by NolanDC
    I'm currently testing my Rails controllers using RSpec. In one controller, I have a model that uses transactions, so that it will not be saved unless another nested model (whose data is filled in using fields_for) is also saved correctly. The tests hit a snag when they reach the transaction. Some debugging output proves that the model is valid and ready to save. However, upon entering the transaction block, the model does not save. Even stranger, the code never reaches the else clause of "if model.save" (It does, however, enter the transaction block). I can only assume this is a problem with my testing a transactional model. Any ideas/hints/solutions?

  • Rails has_one vs belongs_to semantics

    - by Anurag
    I have a model representing a Content item that contains some images. The number of images are fixed as these image references are very specific to the content. For example, the Content model refers to the Image model twice (profile image, and background image). I am trying to avoid a generic has_many, and sticking to multiple has_one's. The current database structure looks like: contents - id:integer - integer:profile_image_id - integer:background_image_id images - integer:id - string:filename - integer:content_id I just can't figure out how to setup the associations correctly here. The Content model could contain two belongs_to references to an Image, but that doesn't seem semantically right cause ideally an image belongs to the content, or in other words, the content has two images. This is the best I could think of (by breaking the semantics): class Content belongs_to :profile_image, :class_name => 'Image', :foreign_key => 'profile_image_id' belongs_to :background_image, :class_name => 'Image', :foreign_key => 'background_image_id' end Am I way off, and there a better way to achieve this association?

  • rake test and test_structure.sql

    - by korinthe
    First of all, I have to run "rake RAILS_ENV=test ..." to get the test suites to hit my test DB. Annoying but ok to live with. However when I do so, I get a long stream of errors like so: > rake RAILS_ENV=test -I test test:units psql:/path/to/project/db/test_structure.sql:33: ERROR: function "armor" already exists with same argument types [and many more] It looks like some DB definitions are getting unnecessarily reloaded. I can't find any mention of this on Google, so I was wondering whether others have seen this? I am using a PostgreSQL database with the following in my environment.rb: config.active_record.schema_format = :sql and using Rails 2.3.5 with rake 0.8.7.

  • Namespace with index action in Rails

    - by yuval
    I have an admin controller located inside /controllers/admin/admin_controller.rb I also have a pages controller located inside /controllers/admin/pages_controller.rb In my routes.rb file, I have the following: map.namespace :admin do |admin| admin.resources :pages end When the user goes to localhost:3000/admin, I'd like the user to see a page with a link to /admin/pages (Pages CRUD) and to / (To go back home). Since I am using a namespace, I cannot have an index action for /admin. How would I get this done and still have my controllers located inside my /controllers/admin folder (rather than using admin as a map.resources component and a has_many association to pages). Please note I am only interested in the show action of admin. Thank you!

  • Authlogic: passwords saved in the DB are not working as expected.

    - by user570459
    Hello everyone, Im having trouble with authlogic on my production server. Im able to update passwords in the database but when i try to validate a user using the new password, the validation fails. Please check the below console output. Notice how the salt and crypted_password fields get update before and after the new password is saved. The issue is only on my production server (running passenger). Everything works fine on my development machine. => #<User id: 3, login: "saravk", email: "[email protected]", crypted_password: "9bc86247105e940bb748ab680c0e77d9c44a82ea", salt: "WdVpQIdwl68k8lJWOU"> irb(main):003:0> u.password = "kettik123" => "kettik123" irb(main):004:0> u.password_confirmation = "kettik123" => "kettik123" irb(main):005:0> u.save! => true irb(main):006:0> u.valid_password?("kettik123") => true irb(main):007:0> u.reload => #<User id: 3, login: "saravk", email: "[email protected]", crypted_password: "f059007c56f498a12c63209c849c1e65bb151174", salt: "lVmmczhyGE0gxsbV421A"> irb(main):008:0> u.valid_password?("kettik123") => false The authlogic configuration in my User model.. class User < ActiveRecord::Base acts_as_authentic do |c| c.login_field :email c.validate_login_field false c.validate_email_field false c.perishable_token_valid_for = 1.day c.disable_perishable_token_maintenance = true end I use the email field as the main key for the user. Also the email field is allowed to be blank in some cases (eg a facebook user) Also i belive that my schema is proper (in terms of the length of the salt & crypted password fields) create_table "users", :force => true do |t| t.string "login" t.string "email" t.string "crypted_password", :limit => 128, :default => "" t.string "salt", Any help on this would be highly appreciated. Thanks.

  • How to go 'back' 2 levels?

    - by Joe McGuckin
    From the list view of my app, I can view a list of records or drill down and edit/update a record. After updating, I want to go directly back to the list view, bypassing a couple of intermediate pages - but I don't simply want to link_to(:action => list) - there's pagination involved. I want to go back to the exact 'list' page I came from. What's the best way? Pass a hidden arg somewhere with the page number? Is there an elegant way to accomplish this?

  • Rails: How to name and create unique divs within a loop?

    - by sscirrus
    I have a view with a div that is looped many times. Each of the created divs need to have a unique ID so I can access them specifically (at the moment, all my divs have the same ID specified in html so whenever I try to access a specific div it just finds the first one). This is the version that I currently have (multiple 'rowBox'es are not discernible). <% @customers.each do |customer| %> <div id="customer" class="rowBox"> ... </div> <% end %> I would like to be able to do something like: <% @customers.each do |customer| %> <div id="box<%=customer.id%>"> ... </div> <% end %> This doesn't seem to work. Any ideas on how to accomplish this?

  • Rails controller not rendering correct view when form is force-submitted by Javascript

    - by whazzmaster
    I'm using Rails with jQuery, and I'm working on a page for a simple site that prints each record to a table. The only editable field for each record is a checkbox. My goal is that every time a checkbox is changed, an ajax request updates that boolean attribute for the record (i.e., no submit button). My view code: <td> <% form_remote_tag :url => admin_update_path, :html => { :id => "form#{lead.id}" } do %> <%= hidden_field :lead, :id, :value => lead.id %> <%= check_box :lead, :contacted, :id => "checkbox"+lead.id.to_s, :checked => lead.contacted, :onchange => "$('#form#{lead.id}').submit();" %> <% end %> </td> In my routes.rb, admin_update_path is defined by map.admin_update 'update', :controller => "admin", :action => "update", :method => :post I also have an RJS template to render back an update. The contents of this file is currently just for testing (I just wanted to see if it worked, this will not be the ultimate functionality on a successful save)... page << "$('#checkbox#{@lead.id}').hide();" When clicked, the ajax request is successfully sent, with the correct params, and the action on the controller can retrieve the record and update it just fine. The problem is that it doesn't send back the JS; it changes the page in the browser and renders the generated Javascript as plain text rather than executing it in-place. Rails does some behind-the-scenes stuff to figure out if the incoming request is an ajax call, and I can't figure out why it's interpreting the incoming request as a regular web request as opposed to an ajax request. I may be missing something extremely simple here, but I've kind-of burned myself out looking so I thought I'd ask for another pair of eyes. Thanks in advance for any info!

  • What is this Hash-like/Tree-like Construct Called?

    - by viatropos
    I want to create a "Config" class that acts somewhere between a hash and a tree. It's just for storing global values, which can have a context. Here's how I use it: Config.get("root.parent.child_b") #=> "value" Here's what the class might look like: class Construct def get(path) # split path by "." # search tree for nodes end def set(key, value) # split path by "." # create tree node if necessary # set tree value end def tree { :root => { :parent => { :child_a => "value", :child_b => "another value" }, :another_parent => { :something => { :nesting => "goes on and on" } } } } end end Is there a name for this kind of thing, somewhere between Hash and Tree (not a Computer Science major)? Basically a hash-like interface to a tree.

  • How to stub Restul-authentication's current_user method?

    - by Thiago
    Hi there, I'm trying to run the following spec: describe UsersController, "GET friends" do it "should call current_user.friends" do user = mock_model(User) user.should_receive(:friends) UsersController.stub!(:current_user).and_return(user) get :friends end end My controller looks like this def friends @friends = current_user.friends respond_to do |format| format.html end end The problem is that I cannot stub the current_user method, as when I run the test, I get: Spec::Mocks::MockExpectationError in 'UsersController GET friends should call current _user.friends' Mock "User_1001" expected :friends with (any args) once, but received it 0 times[0m ./spec/controllers/users_controller_spec.rb:44: current_user is a method from Restful-authentication, which is included in this controller. How am I supposed to test this controller? Thanks in advance

  • Attributes passed to .build() dont show up in the query

    - by Sebastian
    Hi there guys! Hope your all enjoying your hollydays. Ive run into a pretty funny problem when trying to insert rows into a really really simple database table. The basic idea is pretty simple. The user selects one/multiple users in a multiselect which are supposed to be added to a group. This piece of code will insert a row into the user_group_relationships table, but the users id always @group = Group.find(params[:group_id]) params[:newMember][:users].each do |uid| # For debugging purposes. puts 'Uid:'+uid @rel = @group.user_group_relationships.build( :user_id => uid.to_i ) @rel.save end The user id always gets inserted as null even though it is clearly there. You can see the uid in this example is 5, so it should work. Uid:5 ... SQL (0.3ms) INSERT INTO "user_group_relationships" ("created_at", "group_id", "updated_at", "user_id") VALUES ('2010-12-27 14:03:24.331303', 2, '2010-12-27 14:03:24.331303', NULL) Any ideas why this fails?

  • How to update attributes without valitation

    - by Brian Roisentul
    I've got a model with its validations, and I found out that I can't update an attribute without validating the object before. I already tried to add on => :create syntax at the end of each validation line, but I got the same results. My announcement model have the following validations: validates_presence_of :title validates_presence_of :description validates_presence_of :announcement_type_id validate :validates_publication_date validate :validates_start_date validate :validates_start_end_dates validate :validates_category validate :validates_province validates_length_of :title, :in => 6..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :subtitle, :in => 0..255, :on => :save validates_length_of :place, :in => 0..50, :on => :save validates_numericality_of :vacants, :greater_than_or_equal_to => 0, :only_integer => true validates_numericality_of :price, :greater_than_or_equal_to => 0, :only_integer => true My rake task does the following: task :announcements_expiration => :environment do announcements = Announcement.expired announcements.each do |a| #Gets the user that owns the announcement user = User.find(a.user_id) puts a.title + '...' a.state = 'deactivated' if a.update_attributes(:state => a.state) puts 'state changed to deactivated' else a.errors.each do |e| puts e end end end This throws all the validation exceptions for that model, in the output. Does anybody how to update an attribute without validating the model?

  • Is there a way to inspect all controller variables at once in Rails?

    - by m.u.sheikh
    I am exploring an big controller method, with about 10 or so instance variables. Some of them are set in before_filter methods, and some others inside the method itself. I want to inspect them with puts, but dont want to write all of them out example: puts "var1: #{@var1.inspect}....var15: #{@var15.inspect}" Is there a generic method that will display all the instance variables with an @ sign set so far in the current method? If not, what is the next best way to inspect all of them at once without having to write all of them in a puts statement?
