  • Adding RESTful route to Rails app

    - by macek
    I'm reading these two pages resources Adding more RESTful actions The Rails Guides page shows map.resources :photos, :new => { :upload => :post } And its corresponding URL /photos/upload This looks wonderful. My routes.rb shows this map.resources :users, :new => { :signup => :get, :register => :post } When I do: [~/my_app]$ rake routes I see the two new routes added signup_new_user GET /users/new/signup(.:format) register_new_user POST /users/new/register(.:format) Note the inclusion of /new! I don't want that. I just want /users/signup and /users/register (as described in the Rails Routing Guide). Any help?

  • acl9 and devise don't seem to work well together

    - by Nik
    I have a user model which is access controlled by ACL9 in userscontroller: ACL9 related stuff before_filter :load_user, :only = [:show] access_control do allow :owner, :of = :user, :to = [:show] end def load_user user = User.find(params[:id]) end in ApplicaitonController I have a rescue_from 'Acl9::AccessDenied', :with = :access_denied def access_denied authenticate_user! # a method from Devise end it is no problem to type in url for sign in page http://localhost:3000/users/sign_in but it is a problem when for example I type in the user page first, which I am to expect to be redirected to sign in page automatically thru the logic above http://localhost:3000/users/1 #= infinite redirect hell. it tries to redirect back to users/1 again(!?) instead of directing to users/sign_in Does anyone have an opinion as to what might be going wrong? Thanks!

  • Nest input inside f.label ( rails form generation )

    - by Mike
    I want to use the f.label method to create my form element labels, however - i want to have the form element nested inside the label. Is this possible? -- From W3C -- To associate a label with another control implicitly, the control element must be within the contents of the LABEL element. In this case, the LABEL may only contain one control element. The label itself may be positioned before or after the associated control. In this example, we implicitly associate two labels with two text input controls: <FORM action="..." method="post"> <P> <LABEL> First Name <INPUT type="text" name="firstname"> </LABEL> <LABEL> <INPUT type="text" name="lastname"> Last Name </LABEL> </P> </FORM>

  • rails expiring cache

    - by ash34
    Hi, I entered some products data into a table using a migration. I need to expire the page and fragment cache when I update, add, delete products from this table. I created a sweeper for this. class ProductSweeper < ActionController::Caching::Sweeper observe Product def after_create expire_cache end def after_save expire_cache end def after_update expire_cache end def after_destroy expire_cache end private def expire_cache expire_page(:controller => 'ProductsController', :action => 'index') expire_fragment 'listed_products' end end Then in script/console I update the product name and saved. When I reload my app in the browser it still gives me a cache hit. Cached fragment hit: views/listed_products (0.2ms) Can someone tell me how to expire this cache. I will not be adding, updating, deleting products through a controller action. thanks, ash

  • One way Has-Many-Through

    - by Hock
    Hello, I have a Category, a Subcategory and a Product model. I have: Category has_many Subcategories Subcategory has_many Products Subcategory belongs_to Category Product belongs_to Subcategory Is there a way to have something like Category has_many Projects through Subcategories ? The 'normal' rails way wouldn't work because "subcategory" doesn't belongs to product so product does not have a subcategory_id field. Instead, I need the query to be something like SELECT * FROM products WHERE id IN category.subcategory_ids Is there a way to do that? Thanks, Nicolás Hock Isaza

  • Why are all response bodies after the first blank in Cucumber?

    - by James A. Rosen
    I'm using Cucumber (0.6.3), Cucumber-Rails (0.3.0), Webrat (0.7.0), and Rails (2.3.5) for some tests. The following scenario passes just fine: Scenario: load one page Given I am on the home page Then I should see "Welcome" The following, however, fails: Scenario: load two pages Given I am on the FAQ pag When I go to the home page Then I should see "Welcome" The problem is that the second @response.body is blank. I added a Rack middleware to get a little more information: class LogEachRequest def initialize(app); @app = app; @count = 0; end def call(env) puts "Processing request # #{@count += 1)" @app.call(env) end end It shows me only one request processed. That is, it only ever prints out Processing request # 1

  • Resque: Slow worker startup and Forking

    - by David John
    I'm currently moving my application from a Linode setup to EC2. Redis is currently installed on a remote instance with various worker instances interacting with the queue. Thats all going fantastic. My problem is with the amount of time it takes for a worker to be 'instantiated' and slow forking. Starting a worker will usually take between 30 seconds and a minute(from god.rb starting the worker rake task and the worker actively starting work on the queue). I could live with that, but I've not experienced such a wait time on my current Linode production box so I believe its one of my symptoms to a bigger problem. Next issue is that jobs that took a second or less in my previous environment now seem to take about 5 to 10 times longer.. I'm assuming this must be some sort of issue with my Ubuntu install on EC2? One notable difference is that I'm running REE 1.8.7-2010.01 in my new setup, and REE 1.8.6 on the old Linode boxes. Anyone else experienced these issues?

  • Precompile assets for a rails engine

    - by Peter Ehrlich
    In a standard app, I have this line in my production.rb, which creates endpoints for non-default precompiled assets: config.assets.precompile += %w( mobile.css ) My rails engine is a standard Sinatra app. It has its own assets. When on development, these assets are served fine, presumably the web requests are handled by rails and sprockets. On production I'm getting 404s on the assets, and think I have to manually tell sprockets to provide the files. How can this be done without tightly linking? It isin't evident how to set up env-specific initializers for engines. Is this done? Not only, for example, is config/development.rb within the engine not loaded, but there's no way to get the application class itself without knowing its name, in order to modify configuration. And even if there was, it seems that having any engine able to reconfigure the main app would be very bad idea. So maybe its better to let assets handling be done by sinatra itself? Or another instance of sprockets for the engine? How do other engines handle this?

  • Array::include? on ActiveRecord collection not calling op== ?

    - by tribalvibes
    Given a collection of named Foos from ActiveRecord, why does Array.include? not seem to call Foo.== but yet index does? class Foo < ActiveRecord::Base def ==(s) self.name == s end end class Bar < ActiveRecord::Base has_many :foos end bar.foos << Foo.new( :name = 'hmm' ) bar.foos.all.include?('hmm') # does select all from db every time = true bar.foos.include?('hmm') # does not go to db, but does not find the Foo! = false bar.foos.index('hmm') # does not go to db, but does find the Foo[0] ! = 0 bar.foos.index('eh') # no such object = nil I understand shallow about the proxies, but (without a detour into the AR source) why is index seemingly behaving correctly but include? is not !? Is this a bug in the proxy behavior, and/or is this behavior documented somewhere ? Thanks.

  • Using named_scope with counts of child models

    - by Joe Cairns
    Hi, I have a simple parent object having many children. I'm trying to figure out how to use a named scope for bringing back just parents with specific numbers of children. Is this possible? class Foo < ActiveRecord::Base has_many :bars named_scope :with_no_bars, ... # count of bars == 0 named_scope :with_one_bar, ... # count of bars == 1 named_scope :with_more_than_one_bar, ... # count of bars > 1 end class Bar < ActiveRecord::Base belongs_to :foo end I'm hoping to do something like Foo.with_one_bar I could write methods on the parent class for something like this, but I'd rather have the power of the named scope

  • Why does Rails screw up timezones when I am editing a resource?

    - by DJTripleThreat
    Steps to produce this: prompt>rails test_app prompt>cd test_app prompt>script/generate scaffold date_test my_date:datetime prompt>rake db:migrate now edit your app/views/date_tests/edit.html.erb: <h1>Editing date_test</h1> <% form_for(@date_test) do |f| %> <%= f.error_messages %> <p> RIGHT!<br/> <%= text_field_tag @date_test, f.object.my_date %> </p> <p> WRONG!<br /> <%= f.text_field :my_date %> </p> <p> <%= f.submit 'Update' %> </p> <% end %> <%= link_to 'Show', @date_test %> | <%= link_to 'Back', date_tests_path %> now edit your config/environment.rb: #add this config.time_zone = 'Central Time (US & Canada)' This recreates the problem I am having in my actual app. The problem with my app is that I'm storing a date in a hidden field and rendering a "user friendly" version. Creating a resource works fine but as soon as I try to edit it the time changes (it adds the difference between my current time zone configuration and UTC). go to http://localhost:3000/date_tests/new and save the time then go to reedit it and you will have two different representations of the date/time one which will save incorrectly and the other that will.

  • How do I implement aasm in Rails 3 for what I want it to do?

    - by marcamillion
    I am a Rails n00b and have been advised that in order for me to keep track of the status of my user's accounts (i.e. paid, unpaid (and therefore disabled), free trial, etc.) I should use an 'AASM' gem. So I found one that seems to be the most popular: https://github.com/rubyist/aasm But the instructions are pretty vague. I have a Users model and a Plan model. User's model manages everything you might expect (username, password, first name, etc.). Plan model manages the subscription plan that users should be assigned to (with the restrictions). So I am trying to figure out how to use the AASM gem to do what I want to do, but no clue where to start. Do I create a new model ? Then do I setup a relationship between my User model and the model for AASM ? How do I setup a relationship? As in, a user 'has_many' states ? That doesn't seem to make much sense to me. Any guidance would be really appreciated. Thanks. Edit: If anyone else is confused by AASMs like myself, here is a nice explanation of their function in Rails by the fine folks at Envy Labs: http://blog.envylabs.com/2009/08/the-rails-state-machine/ Edit2: How does this look: include AASM aasm_column :current_state aasm_state :paid aasm_state :free_trial aasm_state :disabled #this is for accounts that have exceed free trial and have not paid #aasm_state :free_acct aasm_event :pay do transitions :to => :paid, :from => [:free_trial, :disabled] transitions :to => :disabled, :from => [:free_trial, :paid] end

  • Nokogiri changing custom elements

    - by dagda1
    Hi, I have sample html that I have marked up with some special tags that will be used by a different program, an example of the html is below. You should note the <START:organization>..<END> elements. <html> <head/> <body> <ul> <li> <START:organization> Advanced Integrated Pest Management <END> </li> <li> <START:organization> American Bakers Association <END> </li> </ul> </body> </html> I wanted to use nokogiri to preprocess the html to easily remove irrelevant tags like <script>. I created the following extension to the nokogiri document class: module Nokogiri module HTML class Document def prepare_html xpath("//script").remove to_html.remove_new_lines end end end end The problem is that nokogiri is changing the <START:organization> element to <organization>. Is there anyway that I can preserve the htnl to maintain my custom markup tags? Thanks Paul

  • How to implement a tagging plugin for jQuery

    - by anxiety
    Goal: To implement a jQuery plugin for my rails app (or write one myself, if necessary) that creates a "box" around text after a delimiter is typed. Example: With tagging on SO, the user begins typing a tag, then selects one from the drop-down list provided. The input field recognizes that a tag has been selected, puts a space and then is ready for the next tag. Similarly, I am attempting to use this plugin to put a box around the previously entered tag before moving to to accept the next tag/input. The instructions in the README.txt seem simple enough, however I have been receiving a $(".tagbox").tagbox is not a function error when debugging my app with firebug. Here is what I have in my application.js: $(document).ready( function(){ $('.tagbox').tagbox({ separator: /\[,]/, // specifying comma separation for <code>tags</code> }); }); And here is my _form.html.erb: <% form_for @tag do |f| %> <%= f.error_messages %> <p> <%= f.label :name %><br /> <%= text_field :tag, :name, { :method => :get, :class => "tagbox" } %> </p> <p><%= f.submit "Submit" %></p> <% end %> I have omitted some other code (namely the implementation of an autocomplete plugin) existing within my _form.html.erb and application.js for sake of readability. The inclusion or exclusion of this omitted code does not affect the performance of this plugin. I have included all of the necessary files for the tagbox plugin (as well as application.js after all other included JS files) within the javascript_include_tag in my application.html.erb file. I'm pretty much confused as to why I'd be getting this "not a function" error when jquery.tagbox.js clearly defines the function and is included in the head of my html page in question. I've been struggling with this plugin for longer than I'd like to admit, so any help would really be appreciated. And, of course, I'm open to any other plugins or from-scratch suggestions you may have in mind.. This tagbox plugin does not seem to have a wealth of documentation or any currently working examples. Also to note, I'm trying to avoid using jrails. Thanks for your time

  • Adding defaults and indexes to a script/generate command in a Rails Template?

    - by charliepark
    I'm trying to set up a Rails Template that would allow for comprehensive set-up of a specific Rails app. Using Pratik Naik's overview (http://m.onkey.org/2008/12/4/rails-templates), I was able to set up a couple of scaffolds and models, with a line that looks something like this ... generate("scaffold", "post", "title:string", "body:string") I'm now trying to add in Delayed Jobs, which normally has a migration file that looks like this: create_table :delayed_jobs, :force => true do |table| table.integer :priority, :default => 0 # Allows some jobs to jump to the front of the queue table.integer :attempts, :default => 0 # Provides for retries, but still fail eventually. table.text :handler # YAML-encoded string of the object that will do work table.text :last_error # reason for last failure (See Note below) table.datetime :run_at # When to run. Could be Time.now for immediately, or sometime in the future. table.datetime :locked_at # Set when a client is working on this object table.datetime :failed_at # Set when all retries have failed (actually, by default, the record is deleted instead) table.string :locked_by # Who is working on this object (if locked) table.timestamps end So, what I'm trying to do with the Rails template, is to add in that :default = 0 into the master template file. I know that the rest of the template's command should look like this: generate("migration", "createDelayedJobs", "priority:integer", "attempts:integer", "handler:text", "last_error:text", "run_at:datetime", "locked_at:datetime", "failed_at:datetime", "locked_by:string") Where would I put (or, rather, what is the syntax to add) the :default values in that? And if I wanted to add an index, what's the best way to do that?

  • Smartest way to import massive datasets into a Rails application?

    - by williamjones
    I've got multiple massive (multi gigabyte) datasets I need to import into a Rails app. The datasets are currently each in their own database on my development machine, and I need to read from them and create rows in tables in my Rails database based on the information they contain. The tables in my Rails database will not be exactly the same as the tables in the source databases. What's the smartest way to go about this? I was thinking migrations, but I'm not exactly sure how to connect the migration to the databases, and even if that is possible, is that going to be ridiculously slow?

  • Creating a gallery in Rails

    - by raphael_turtle
    I'm creating a simple site with a gallery. I have a photos model which has a page for each photo with it's info and an image. I'm unsure how to create a gallery from the photo's. The gallery model has_many photos, the photos model has_and_belongs_to_many galleries. I thought of adding a gallery.title field on each photo page so I'd have a list of photo's for each gallery then display them in a view. Is this a good way to make a gallery? (I've looked through the code on some gallery apps on github, but most are outdated are too complicated for my needs.)
