  • Using a helper method in a mailer that is defined in a controller

    - by Horace Loeb
    The helper method current_user is defined and made available as a helper in ApplicationController like this: class ApplicationController < ActionController::Base helper_method :current_user def current_user return @current_user if defined?(@current_user) @current_user = current_user_session && current_user_session.record end end My question is how I can use the current_user helper method in a mailer template (obviously it will always return nil, but I'm trying to render a partial that depends on it). Normally when I want to use helpers in a mailer, I do something like add_template_helper(SongsHelper), but since the helper is defined in a class instead of a module I'm not sure what to do

  • Easier way to generate paths

    - by Horace Loeb
    Songs on Rap Genius have paths like /lyrics/The-notorious-b-i-g-ft-mase-and-puff-daddy/Mo-money-mo-problems which are defined in routes.rb as: map.song '/lyrics/:artist_slug/:title_slug', :controller => 'songs', :action => 'show' When I want to generate such a path, I use song_url(:title_slug => song.title_slug, :artist_slug => song.artist_slug). However, I'd much prefer to be able to type song_url(some_song). Is there a way I can make this happen besides defining a helper like: def x_song_path(song) song_path(:title_slug => song.title_slug, :artist_slug => song.artist_slug) end

  • Generate an HTML table from an array of hashes in Ruby

    - by Horace Loeb
    What's the best way (ideally a gem, but a code snippet if necessary) to generate an HTML table from an array of hashes? For example, this array of hashes: [{"col1"=>"v1", "col2"=>"v2"}, {"col1"=>"v3", "col2"=>"v4"}] Should produce this table: <table> <tr><th>col1</th><th>col2</th></tr> <tr><td>v1</td><td>v2</td></tr> <tr><td>v3</td><td>v4</td></tr> </table>

  • Re-using unit tests for models using STI

    - by TenJack
    I have a number of models that use STI and I would like to use the same unit test to test each model. For example, I have: class RegularList < List class OtherList < List class ListTest < ActiveSupport::TestCase fixtures :lists def test_word_count list = lists(:regular_list) assert_equal(0, list.count) end end How would I go about using the test_word_count test for the OtherList model. The test is much longer so I would rather not have to retype it for each model. Thanks.

  • How do I insert an input's value into a separate form?

    - by ryan
    I'm making a tool for my university that allows students to create a list of classes by doing the following: Searching by course title for their course via an autocomplete input field. Adding that course to a separate form that upon being submitted creates a course list. I am trying to link the autocomplete and the course list form with an 'add to course list' button that inserts a hidden input field into the course list form which can subsequently be submitted by a 'create course list' button. My question is this: How do I take the value of the autocomplete input and insert it into the course list form without using AJAX? So far I have something like the following: <%= text_field_with_auto_complete :course, :title, :size => 40 %> <%= link_to_function "Add to Course List" do |page| page.insert_html :top, :course_list, hidden_field(:courses, :course, {:value => "$('course_title').value"}) %> <% form_for(@course_list) do |f|%> <div id="course_list">Insert selected courses here.</div> <% end %>

  • Quick help refactoring Ruby Class

    - by mplacona
    I've written this class that returns feed updates, but am thinking it can be further improved. It's not glitchy or anything, but as a new ruby developer, I reckon it's always good to improve :-) class FeedManager attr_accessor :feed_object, :update, :new_entries require 'feedtosis' def initialize(feed_url) @feed_object = Feedtosis::Client.new(feed_url) fetch end def fetch @feed_object.fetch end def update @updates = fetch end def updated? @updates.new_entries.count > 0 ? true : false end def new_entries @updates.new_entries end end As you can see, it's quite simple, but the things I'm seeing that aren't quite right are: Whenever I call fetch via terminal, it prints a list with the updates, when it's really supposed return an object. So as an example, in the terminal if I do something like: client = Feedtosis::Client.new('http://stackoverflow.com/feeds') result = client.fetch I then get: <Curl::Easy http://stackoverflow.com/feeds> Which is exactly what I'd expect. However, when doing the same thing with "inniting" class with: FeedManager.new("http://stackoverflow.com/feeds") I'm getting the object returning as an array with all the items on the feed. Sure I'm doing something wrong, so any help refactoring this class will he greatly appreciated. Also, I'd like to see comments about my implementation, as well as any sort of comment to make it better would be welcome. Thanks in advance

  • Let a question always :include its author, how?

    - by Freewind
    class Question < ActiveRecord::Base belongs_to :author end class Author < ActiveRecord::Base has_many :questions end When I find some questions, I usually need to get their authors at the same time, so I use: Question.find(:all, :include=>:authors) But I don't write the ":include" part everywhere. I hope I can define the "include" somewhere only once, and when I find questions, the author will be automaticly loaded. Is there any way to do this?

  • weird behavior with acts_as_taggable_on

    - by macek
    For some reason, tags aren't showing up on a taggable object when an tagger is specified. testing the post class Post < ActiveRecord::Base acts_as_taggable_on :tags belongs_to :user end >> p = Post.first => #<Post id: 1, ...> >> p.is_taggable? => true >> p.tag_list = "foo, bar" => "foo, bar" >> p.save => true >> p.tags => [#<Tag id: 1, name: "foo">, #<Tag id: 2, name: "bar">] testing the user class User < ActiveRecord::Base acts_as_tagger has_many :posts end >> u = User.first => #<User id: 1, ...> >> u.is_tagger? => true >> u.tag(p, :with => "hello, world", :on => :tags) => true >> u.owned_tags => [#<Tag id: 3, name: "hello">, #<Tag id: 4, name: "world">] refresh the post >> p = Post.first => #<Post id: 1 ...> >> p.tags => [#<Tag id: 2, name: "bar">, #<Tag id: 1, name: "foo">] Where's the hello and world tags? Miraculously, if I modify the database directly to set tagger_id and tagger_type to NULL, the two missing tags will show up. I suspect there's something wrong with my User model? What gives?

  • OpenID register on login (authlogic_openid)

    - by Glex
    What is the proper way to register users automatically when they log in with openid? I am using authlogic with an authlogic-oid gem (and an older version of openid_authentication). The stuff I read online so far seems to be obsolete. Does anyone know the proper way to do it with the new gem? What I do now is: options = params[:user_session] || {} [:openid_identifier].each { |k| options[k] = params[k] if params[k] } @user_session = UserSession.new(options) @user_session.save do |result| if result flash[:notice] = "Login successful! (#{result.inspect})" redirect_back_or_default account_url else render :action => :new end end By the way, I don't see the Login Successful flash (but that is not that big of a deal).

  • Why does the OAuth Unauthorized Error (401) happen?

    - by ming yeow
    Sometimes an Twitter OAuth is successfully executed, but an unauthorized error is thrown. I get about 50 of these on a daily basis. It is worrying, because I have no idea how that might be reproduced. What are the different cases where this error happens, and how can this be fixed or prevented?

  • best practice for boolean REST results

    - by Andrew Patterson
    I have a resource /system/resource And I wish to ask the system a boolean question about the resource that can't be answered by processing on the client (i.e I can't just GET the resource and look through the actual resource data - it requires some processing on the backend using data not available to the client). eg /system/resource/related/otherresourcename I want this is either return true or false. Does anyone have any best practice examples for this type of interaction? Possibilities that come to my mind: use of HTTP status code, no returned body (smells wrong) return plain text string (True, False, 1, 0) - Not sure what string values are appropriate to use, and furthermore this seems to be ignoring the Accept media type and always returning plain text come up with a boolean object for each of my support media types and return the appropriate type (a JSON document with a single boolean result, an XML document with a single boolean field). However this seems unwieldy. I don't particularly want to get into a long discussion about the true meaning of a RESTful system etc - I have used the word REST in the title because it best expresses the general flavour of system I am designing (even if perhaps I am tending more towards RPC over the web rather than true REST). However, if someone has some thoughts on how a true RESTful system avoids this problem entirely I would be happy to hear them.

  • read/write_attribure on associations

    - by artemave
    read/write_attribute is a great way to enhance default accessors generated by ActiveRecord. Like this for example: def price read_attribute(:price) or "This item is priceless and you are by the way #{User.current.login}" end The same however does not seem to be working with associations. Demonstration: class Product < ActiveRecord::Base has_and_belongs_to_many :stores end Then >> a = Product.first => #<Product id: 1, name: "awesome product", created_at: "2010-05-07 12:11:00", updated_at: "2010-05-07 12:11:00"> >> a.stores => [#<Store id: 1, name: "ikea", created_at: "2010-05-07 12:11:28", updated_at: "2010-05-07 12:11:28">] >> a.read_attribute(:stores) => nil >> So, is there some sort of read/write_association? Or, if not, is there a reason not to have one?

  • Get used color names from image

    - by atmorell
    Hello, I would like to check what colors is present in a image. This will be stored in the database and used for a search form. (red=1, green=1, blue=0, yellow=1, black=1, white=1 etc.) img = Magick::Image.read('phosto-file.jpg').first img = img.quantize(10 h = img.color_histogram pp h {red=12815, green=18494, blue=15439, opacity=0=>13007, red=44662, green=47670, blue=51967, opacity=0=>18254, red=17608, green=43331, blue=48321, opacity=0=>11597, red=21105, green=25865, blue=39467, opacity=0=>10604, red=15125, green=36629, blue=22824, opacity=0=>10223, red=52102, green=42405, blue=10063, opacity=0=>12928, red=39043, green=28726, blue=40855, opacity=0=>7728, red=10410, green=8880, blue=7826, opacity=0=>13795, red=25484, green=25337, blue=24235, opacity=0=>7351, red=44485, green=12617, blue=11169, opacity=0=>14513} How do I convert the 10 values to color names? red, green, NOMATCH, yellow, black, white etc. Only need the rough color name - not LimeGreen but Green etc. Best regards.

  • Can nested attributes be used in combination with inheritance?

    - by FoxDemon
    I have the following classes: Project Person Person Developer Person Manager In the Project model I have added the following statements: has_and_belongs_to_many :people accepts_nested_attributes_for :people And of course the appropriate statements in the class Person. How can I add an Developer to a Project through the nested_attributes method? The following does not work: @p.people_attributes = [{:name => "Epic Beard Man", :type => "Developer"}] @p.people => [#<Person id: nil, name: "Epic Beard Man", type: nil>] As you can see the type attributes is set to nil instead of Developer.

  • Simple cropping with Paperclip

    - by collimarco
    I would like to crop images on upload using Paperclip to get square thumbs from the center of the original picture. I find out a method in documentation that seems to do exactly what I want: transformation_to(dst, crop = false) The problem is that I can't figure out where to use this method. It would be great to simply pass something as a parameter here: has_attached_file :picture, :styles = { :medium = "600x600", :thumb = "something here" }
