  • Passenger error message I can't figure out

    - by Sam Kong
    Hi, I am testing Rails 3 on DreamHost which just installed Rails 3. I created a simple controller and it failed. Browser shows 500 error (Internal Server Error) and the log shows the following message. Could not find i18n-0.5.0 in any of the sources Try running `bundle install`. *** Exception EOFError in spawn manager (Unexpected end-of-file detected.)

  • Configure Rails app to retrieve ALL emails from inbox

    - by Kartik Rao
    I'm using the following code to retrieve emails from my Gmail inbox. def get_mail Net::POP3.enable_ssl(OpenSSL::SSL::VERIFY_NONE) Net::POP3.start('pop.gmail.com', 995, "uname","pass") do |pop| unless pop.mails.empty? pop.each_mail do |mail| email = TMail::Mail.parse(mail.pop) email_obj=EmailedQueries.new email_obj.save_email(email.from,email.subject,email.body_html) end end end end This works just fine, but it retrieves only new mails from the inbox. Instead, I want a seperate function that will retrieve ALL emails from the inbox. This function will be used rarely. I wont be retrieving all mails all the time. Only when necessary. Thanks!

  • Is there a way to undo Mocha stubbing of any_instance in Test::Unit

    - by Craig Walker
    Much like this question, I too am using Ryan Bates's nifty_scaffold. It has the desirable aspect of using Mocha's any_instance method to force an "invalid" state in model objects buried behind the controller. Unlike the question I linked to, I'm not using RSpec, but Test::Unit. That means that the two RSpec-centric solutions there won't work for me. Is there a general (ie: works with Test::Unit) way to remove the any_instance stubbing? I believe that it's causing a bug in my tests, and I'd like to verify that.

  • Putting update logic in your migrations

    - by Daniel Abrahamsson
    A couple of times I've been in the situation where I've wanted to refactor the design of some model and have ended up putting update logic in migrations. However, as far as I've understood, this is not good practice (especially since you are encouraged to use your schema file for deployment, and not your migrations). How do you deal with these kind of problems? To clearify what I mean, say I have a User model. Since I thought there would only be two kinds of users, namely a "normal" user and an administrator, I chose to use a simple boolean field telling whether the user was an adminstrator or not. However, after I while I figured I needed some third kind of user, perhaps a moderator or something similar. In this case I add a UserType model (and the corresponding migration), and a second migration for removing the "admin" flag from the user table. And here comes the problem. In the "add_user_type_to_users" migration I have to map the admin flag value to a user type. Additionally, in order to do this, the user types have to exist, meaning I can not use the seeds file, but rather create the user types in the migration (also considered bad practice). Here comes some fictional code representing the situation: class CreateUserTypes < ActiveRecord::Migration def self.up create_table :user_types do |t| t.string :name, :nil => false, :unique => true end #Create basic types (can not put in seed, because of future migration dependency) UserType.create!(:name => "BASIC") UserType.create!(:name => "MODERATOR") UserType.create!(:name => "ADMINISTRATOR") end def self.down drop_table :user_types end end class AddTypeIdToUsers < ActiveRecord::Migration def self.up add_column :users, :type_id, :integer #Determine type via the admin flag basic = UserType.find_by_name("BASIC") admin = UserType.find_by_name("ADMINISTRATOR") User.all.each {|u| u.update_attribute(:type_id, (u.admin?) ? admin.id : basic.id)} #Remove the admin flag remove_column :users, :admin #Add foreign key execute "alter table users add constraint fk_user_type_id foreign key (type_id) references user_types (id)" end def self.down #Re-add the admin flag add_column :users, :admin, :boolean, :default => false #Reset the admin flag (this is the problematic update code) admin = UserType.find_by_name("ADMINISTRATOR") execute "update users set admin=true where type_id=#{admin.id}" #Remove foreign key constraint execute "alter table users drop foreign key fk_user_type_id" #Drop the type_id column remove_column :users, :type_id end end As you can see there are two problematic parts. First the row creation part in the first model, which is necessary if I would like to run all migrations in a row, then the "update" part in the second migration that maps the "admin" column to the "type_id" column. Any advice?

  • How to: Searchlogic and Tags

    - by bob
    I have installed searchlogic and added will_paginate etc. I currently have a product model that has tagging enabled using the acts_as_taggable_on plugin. I want to search the tags using searchlogic. Here is the taggable plugin page: http://github.com/mbleigh/acts-as-taggable-on Each product has a "tag_list" that i can access using Product.tag_list or i can access a specific tag using Product.tags[0] I can't find the scope to use for searching however with search logic. Here is my part of my working form. <p> <%= f.label :name_or_description_like, "Name" %><br /> <%= f.text_field :name_or_description_like %> </p> I have tried :name_or_description_or_tagged_with_like and :name_or_description_or_tags_like and also :name_or_description_or_tags_list_like to try and get it to work but I keep have an error that says the options i have tried are not found (named scopes not found). I am wondering how I can get this working or how to create my own named_scope that would allow me to search the tags added to each product by the taggable plugin. Thanks!

  • Mysql results sorted by list which is unique for each user

    - by ADAM
    Ive got a table of thousands of products and 50 or so authenticated users. These users all show the products on their own web sites and they all require the ability to have them ordered differently. Im guesing i need some kind of seperate table for the orders which contains the product_id, user_id and order column? How do i do this the most efficiently in mysql so as to be very fast, and not slow down if i get millions of products in the database. Is it even wise to do it in mysql or should i be using some kind of other index like solr/lucene? My Product table is called "products" My User table is called "users" A good example of the functionality i need is google search where you can order/supress the results if you are logged in. edit: the product results will be paginated and the users have the authority to edit the products, so its not just ready only

  • Named Blueprints with factory_girl

    - by Jason Nerer
    I am using Factory Girl but like the machinist syntax. So I wonder, if there is any way creating a named blueprint for class, so that I can have something like that: User.blueprint(:no_discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader false name "foolish" salt "21746899800.223524289203464" end User.blueprint(:discount_user) do admin false hashed_password "226bc1eca359a09f5f1b96e26efeb4bb1aeae383" is_trader true name "deadbeef" salt "21746899800.223524289203464" discount_rate { DiscountRate.make(:rate => 20.00) } end DiscountRate.blueprint do rate {10} not_before ... not_after ... end Is there a way making factory_girl with machinist syntax acting like that? I did not find one. Help appreciated. Thx in advance Jason

  • 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).

  • 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.

  • 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?

  • adding model validation errors in rescue

    - by ash34
    I have the following model with a virtual attribute class Mytimeperiod < ActiveRecord::Base validates presence of :from_dt validates_format_of :from_dt, :with => /\A\d{2}\/\d{2}\/\d{4}\Z/, :message => "format is mm/dd/yyyy" def from_dt self.from_date.strftime("%m/%d/%Y") if !self.from_date.blank? end def from_dt=(from_dt) self.from_date = Date.parse(from_dt) rescue self.errors.add_to_base("invalid from dt") end end I am using <%= f.error_messages %> to display the error messages on the form. I am using from_dt as a virtual attribute (string). The 'presence of' and 'format of' validation errors show up on the form, but when the user enters an invalid date format on the form and Date.Parse raises an exception I have a 'errors.add_to_base' statement in the rescue clause. Can anyone tell me why this error does not show up in the form error messages when I disable the 'format of' validation. thanks.

  • Rails uniqueness constraint and matching db unique index for null column

    - by Dave
    I have the following in my migration file def self.up create_table :payment_agreements do |t| t.boolean :automatic, :default => true, :null => false t.string :payment_trigger_on_order t.references :supplier t.references :seller t.references :product t.timestamps end end I want to ensure that if a product_id is specified it is unique but I also want to allow null so I have the following in my model: validates :product_id, :uniqueness => true, :allow_nil => true Works great but I should then add an index to the migration file add_index :payment_agreements, :product_id, :unique => true Obviously this will throw an exception when two null values are inserted for product_id. I could just simply omit the index in the migration but then there's the chance that I'll get two PaymentAgreements with the same product_id as shown here: Concurrency and integrity My question is what is the best/most common way to deal with this problem

  • DOM Elements with same id and jQuery

    - by Steve
    Hi I have multiple elements with the same structure in my application. Second div element's id varies as per the comment id in the db which is unique. There are elements with the id 'vote_up' and 'vote_down'. This gets repeated for each comment.What happens is that, as I mentioned, there are multiple comments. I want to perform an Ajax request. First of this structure functions properly using ajax, but the rest does an http request. Btw I am developing a rails application and I am using jQuery. <div id="post_comment"> john<i> says </i> Comment<br/> <div id="comment_10_div"> **<form action="/comments/vote_up" id="vote_up" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[post_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote up" /> </form> <label id="comment_10">10</label> **<form action="/comments/vote_down" id="vote_down" method="post">** <div style="margin:0;padding:0;display:inline"> <input name="authenticity_token" type="hidden" value="w873BgYHLxQmadUalzMRUC+1ql4AtP3U7f78dT8x9ho=" /> </div> <input id="Comment_place_id" name="Comment[place_id]" type="hidden" value="3" /> <input id="Comment_id" name="Comment[id]" type="hidden" value="10" /> <input id="Comment_user_id" name="Comment[user_id]" type="hidden" value="2" /> <input name="commit" type="submit" value="Vote Down" /> </form> </div> Can you please help me to solve this Thanks

  • Ordering columns in Rails, cakephp style.

  • eventmachine and external scripts via backticks

    - by Maciek
    I have a small HTTP server script I've written using eventmachine which needs to call external scripts/commands and does so via backticks (``). When serving up requests which don't run backticked code, everything is fine, however, as soon as my EM code executes any backticked external script, it stops serving requests and stops executing in general. I noticed eventmachine seems to be sensitive to sub-processes and/or threads, and appears to have the popen method for this purpose, but EM's source warns that this method doesn't work under Windows. Many of the machines running this script are running Windows, so I can't use popen. Am I out of luck here? Is there a safe way to run an external command from an eventmachine script under Windows? Is there any way I could fire off some commands to be run externally without blocking EM's execution? edit: the culprit that seems to be screwing up EM the most is my usage of the Windows start command, as in: start java myclass. The reason I'm using start is because I want those external scripts to start running and keep running after the EM request is served

  • find(:all) and then add data from another table to the object

    - by Koning Baard XIV
    I have two tables: create_table "friendships", :force => true do |t| t.integer "user1_id" t.integer "user2_id" t.boolean "hasaccepted" t.datetime "created_at" t.datetime "updated_at" end and create_table "users", :force => true do |t| t.string "email" t.string "password" t.string "phone" t.boolean "gender" t.datetime "created_at" t.datetime "updated_at" t.string "firstname" t.string "lastname" t.date "birthday" end I need to show the user a list of Friendrequests, so I use this method in my controller: def getfriendrequests respond_to do |format| case params[:id] when "to_me" @friendrequests = Friendship.find(:all, :conditions => { :user2_id => session[:user], :hasaccepted => false }) when "from_me" @friendrequests = Friendship.find(:all, :conditions => { :user1_id => session[:user], :hasaccepted => false }) end format.xml { render :xml => @friendrequests } format.json { render :json => @friendrequests } end end I do nearly everything using AJAX, so to fetch the First and Last name of the user with UID user2_id (the to_me param comes later, don't worry right now), I need a for loop which make multiple AJAX calls. This sucks and costs much bandwidth. So I'd rather like that getfriendrequests also returns the First and Last name of the corresponding users, so, e.g. the JSON response would not be: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3 } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4 } } ] but rather: [ { "friendship": { "created_at": "2010-02-19T13:51:31Z", "user1_id": 2, "updated_at": "2010-02-19T13:51:31Z", "hasaccepted": false, "id": 11, "user2_id": 3, "firstname": "Jon", "lastname": "Skeet" } }, { "friendship": { "created_at": "2010-02-19T16:31:23Z", "user1_id": 2, "updated_at": "2010-02-19T16:31:23Z", "hasaccepted": false, "id": 12, "user2_id": 4, "firstname": "Mark", "lastname": "Gravell" } } ] I thought of a for loop in the getfriendrequests method, but I don't know how to implement this, and maybe there is an easier way. It must also work for XML. Can anyone help me? Thanks
