I've just installed the devise-twitter gem on the following system:

Ubuntu 10.04
ruby 1.8.7 (2010-01-10 patchlevel 249)
Rails 3.0.0
Warden 0.10.7
oauth 0.4.3
devise (master, 9/13/2010)
Nginx fronting Passenger

I'm adding Twitter to a sample app that I put together that does Facebook authentication using Devise's OAuth2 features.

When I attempt to authenticate using Twitter, I am correctly prompted for my Twitter credentials. But after I submit correct credentials, the postback fails with an error. Specifically:

undefined method `twitter_handle=' for nil:NilClass

The top of the stack trace is:

activesupport (3.0.0) lib/active_support/whiny_nil.rb:48:in method_missing' devise-twitter (0.1.1) lib/devise/twitter/warden.rb:12:in_find_user_by_access_token'

and examination of the code indicates that @env['warden'].user is nil, which is causing this issue.

I've attached env['warden'] to the end of this comment. Any idea what's going on here? Happy to provide more info as necessary.

env['warden']: http://pastie.org/1157066

This only happens when a user is registering for the first time.

Devise-twitter does not log the user in after navigating to /user/sign_in

It saves the user in the db, but does not log the user. To log the user in, the user would have to navigate to /user/sign_in a second time

Am I missing something or is this a bug?

I am getting this error when starting my app

/usr/local/rvm/gems/ruby-1.9.2-p0/gems/warden-1.0.0/lib/warden/strategies.rb:11:in `add': authenticate! is not declared in the :twitter_oauth strategy (NoMethodError)

When coming back from Twitter I always get this error:

undefined method `twitter_handle=' for nil:NilClass

Any idea why?

Is there a way to connect to twitter's api to upate a users status using this gem? Or should another approach be used for this?

In theory the app should communicate with http://dev.twitter.com/doc/post/statuses/update to update a users status. Is this already supported or still has to be implemented?

Hello there,

I've installed:

devise (1.4.2)
devise-twitter (0.1.1)

and have followed the instructions on the devise-twitter page.

I'm calling: http://localhost:3000/user/sign_in/twitter

and get

NameError

uninitialized constant Devise::Models::TwitterOauth

app/models/user.rb:12

class User < ActiveRecord::Base

To use devise-twitter don't forget to include the :twitter_oauth module:

e.g. devise :database_authenticatable, ... , :twitter_oauth

IMPORTANT: If you want to support sign in via twitter you MUST remove the

:validatable module, otherwise the user will never be saved

since it's email and password is blank.

:validatable checks only email and password so it's safe to remove

Include default devise modules. Others available are:

:token_authenticatable, :confirmable, :lockable and :timeoutable

devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :twitter_oauth

Setup accessible (or protected) attributes for your model

attr_accessible :email, :password, :password_confirmation, :remember_me
end

What am I missing?

Thanks

I'm getting error because the gem is using an activerecotd specific find. I've changed it by a monkey patch like this. but it's better to use a general format of finder which is compatible with most of ORMs

def self.find_by_twitter_oauth_token_and_twitter_oauth_secret(*vals)
  User.find(:first, :conditions => { :twitter_oauth_token => vals[0], :twitter_oauth_secret => vals[1]  })
end

I'm workind with mongoid (learning) and devise
i follow up the "how to" but when i try to test i have this error
uninitialized constant Devise::Twitter

This error occurred while loading the following files:
config/routes.rb

Mi routes.rb

Weird::Application.routes.draw do
root :to => "home#index"
devise_for :users do
match '/users/sign_in/twitter' => Devise::Twitter::Rack::Signin
match '/users/connect/twitter' => Devise::Twitter::Rack::Connect
end
resources :users, :only => :show
end

I can't find the problem.... ideas?

The devise oauth2 gem supports custom callback routes after signin in. devise-twitter should support them too.

Currently if warden.user is nil we crash. devise-twitter should set a flash message (from i18n) and redirect back.

I'm encountering a 401 Unauthorized error when oauth tries to acquire a request token. I've been trying to figure out what the issue is for the past hour with no luck.

I've got my consumer_key and consumer_secret all setup in devise_twitter.rb. What else could I have wrong?

Thanks.

In my application I have 2 different devise scopes. When using devise-twitter to do the perform_connect, upon the invocation of Warden::OAuth.access_token_user_finder, the block is using @env['warden'].user to retrieve the currently logged in user which when using multiple scope is nil. Replacing that with @env['warden'].user(@scope) fixes this issue.

Wouldnt it be wise to store the twitter id and have that as the primary field instead of the twitter_handle? If a user decides to change his twitter name in twitter.com, then this gem will create a another user record on the db.

Second, how does the app keep track of users who change their twitter handle? At least with the twitter id, this will always be unique never changing...

If one decides to rollback. An error appears:

rake aborted!
An error has occurred, this and all later migrations canceled:

PGError: ERROR: column "string" of relation "users" does not exist
: ALTER TABLE "users" DROP "string"

The problem is at:

class AddDeviseTwitterFieldsToUsers < ActiveRecord::Migration

......

change_table(:users) do |t|
  t.remove :twitter_handle, :string
  t.remove :twitter_oauth_token, :string
  t.remove :twitter_oauth_secret, :string
end

end

it should be:

change_table(:users) do |t|
  t.remove :twitter_handle
  t.remove :twitter_oauth_token
  t.remove :twitter_oauth_secret
end

The above works if changed. Thought you might want to look at this...

when connecting accounts it would be nice if it can create the user when it doesn't exist
I would like to connect accounts by default

I will try to explain my error with examples

I have one registered user with devise (uokesita, [email protected], etc, ...)

I try to sign in with twitter and my account @uokesita everthing works fine

Then I try to sign in with other twitter account ex: @coders_vzla it creates a new devise user with no email. also works fine

Then if i try to sign in with another twitter account ex: @otheraccount it tries to create a new devise user with no email but it complains since there is another register with no email

How can i solve this?

Hi, great plugin! And I hope that the development goes on for this gem.

I am wondering. I am able to do a sign-in with Twitter. My db stores twitter_handle, twitter_oauth_token and twitter_oauth_secret. However, my user model also has other fields such as: full_name, description, url, followers_count, friends_count, photo_caption, photo_file_name, etc, which are all fields from the user twitter api (http://dev.twitter.com/doc/get/statuses/show/:id)

I need to populate these fields in my local db. How should this be done?

I'm using devise-twitter only for connecting my devise user to Twitter. Since devise-twitter does not have hooks to perform status updates, I attempted to use the twitter gem by jnunemaker. However, since the jnunemaker's class is named Twitter that collides with the warden strategy class name as it attempts to use :twitter (passed from the Devise::Twitter.set) to check if a class is available and that causes errors regarding authenticate! method not being available.

It may make sense to use :devise_twitter as the strategy name so that it doesn't collide with the twitter gem class.
