I implemented Facebook Button with omniauth and It works. I don't find a tutorial to implement Google Button. Could you guide me or share some steps to integate it. Thank you very much.
Here you can find a tutorial:
Gemfile:
gem "omniauth-google-oauth2", "~> 0.2.1"
config/initializers/omniauth.rb:
OmniAuth.config.logger = Rails.logger
Rails.application.config.middleware.use OmniAuth::Builder do
provider :google_oauth2, 'my Google client id', 'my Google client secret', {client_options: {ssl: {ca_file: Rails.root.join("cacert.pem").to_s}}}
end
Terminal Commands:
rails g model user provider uid name oauth_token oauth_expires_at:datetime
rake db:migrate
Terminal Commands:
rails g controller home show
rails g controller Sessions create destroy
config/routes.rb:
GoogleAuthExample::Application.routes.draw do
get 'auth/:provider/callback', to: 'sessions#create'
get 'auth/failure', to: redirect('/')
get 'signout', to: 'sessions#destroy', as: 'signout'
resources :sessions, only: [:create, :destroy]
resource :home, only: [:show]
root to: "home#show"
end
app/models/user.rb:
class User < ActiveRecord::Base
def self.from_omniauth(auth)
where(auth.slice(:provider, :uid)).first_or_initialize.tap do |user|
user.provider = auth.provider
user.uid = auth.uid
user.name = auth.info.name
user.oauth_token = auth.credentials.token
user.oauth_expires_at = Time.at(auth.credentials.expires_at)
user.save!
end
end
end
app/controllers/application_controller.rb:
class ApplicationController < ActionController::Base
protect_from_forgery with: :exception
helper_method :current_user
def current_user
#current_user ||= User.find(session[:user_id]) if session[:user_id]
end
end
app/controllers/sessions_controller.rb:
class SessionsController < ApplicationController
def create
user = User.from_omniauth(env["omniauth.auth"])
session[:user_id] = user.id
redirect_to root_path
end
def destroy
session[:user_id] = nil
redirect_to root_path
end
end
app/views/layouts/application.html.erb:
<!DOCTYPE html>

I have a rails 7.0 application, in my application.html.erb
<body>
<%= yield %>
<div class="signin-container">
<div class="signin-container-inner">
<%- flash.each do |name, msg| -%>
<%= content_tag :div, msg, :id => "flash_#{name}" if msg.is_a?(String) %>
<%- end -%>
</div>
</div>
</body>
When I visit signin page and add some wrong email or password the error message is not showing.
Since Ruby on Rails 7 uses :turbo_stream, we need to make some modifications to get what you need.
First, we let's add a new parent controller for Devise:
# frozen_string_literal: true
# app/controllers/turbo_devise_controller.rb
class TurboDeviseController < ApplicationController
class Responder < ActionController::Responder
def to_turbo_stream
controller.render(options.merge(formats: :html))
rescue ActionView::MissingTemplate => e
if get?
raise e
elsif has_errors? && default_action
render rendering_options.merge(formats: :html, status: :unprocessable_entity)
else
redirect_to navigation_location
end
end
end
self.responder = Responder
respond_to :html, :turbo_stream
end
Second, we also need to tell Devise to use our new controller and also add a class to handle our errors:
# frozen_string_literal: true
# app/config/initializers/devise.rb
# ! Create custom failure for turbo
class TurboFailureApp < Devise::FailureApp
def respond
if request_format == :turbo_stream
redirect
else
super
end
end
def skip_format?
%w(html turbo_stream */*).include? request_format.to_s
end
end
Devise.setup do |config|
...
config.parent_controller = 'TurboDeviseController'
config.navigational_formats = ['*/*', :html, :turbo_stream]
config.warden do |manager|
manager.failure_app = TurboFailureApp
end
...
end
That's it.
More information about it: GoRails - How to use Devise with Hotwire & Turbo.js
Here is a workaround this issue that occurs when using Rails 7, Hotwire, Turbo, and Devise together. By passing data:{turbo: false} along with each Devise form, it can prevent Turbo from conflicting with the Devise authentication process. This should allow Devise to function properly while still using Hotwire and Turbo in your Rails application.
Here is an example of how you might use data:{turbo: false} on a Devise form:
<%= form_for(resource, as: resource_name, url: session_path(resource_name), data: {turbo: false}) do |f| %>
<%= f.label :email %>
<%= f.email_field :email, autofocus: true %>
<%= f.label :password %>
<%= f.password_field :password %>
<%= f.submit "Log in" %>
<% end %>
In this example, the data: {turbo: false} is being passed as an option to the form_for helper method. This tells Turbo to not apply any of its features to this form, which should prevent any conflicts with Devise's authentication process.
im trying create backend under password from database and i cant go through login page :P
My AdminController
class Backend::AdminController < ApplicationController
layout :layout
before_filter :authorize, :except => :login
def authorize
if session[:backend] != true
redirect_to backend_login_path
end
end
private
def layout
if session[:backend] == true
"admin"
else
"login"
end
end
def login
employee = Employee.authenticate(params[:name], params[:password])
if employee
session[:backend] = true
redirect_to backend_root_path, :notice => "Logged in!"
else
flash.now.alert = "Invalid login"
end
end
def logout
session[:backend] = nil
redirect_to backend_login_path, :notice => "Logged out!"
end
end
My Routes
match "backend/login" => "backend/admin#login"
match "backend/logout" => "backend/admin#logout"
My Login page
<% flash.each do |name, msg| %>
<%= content_tag :div, msg, :id => "flash_#{name}" %>
<% end %>
<h1>Log in</h1>
<%= form_tag backend_login_path do %>
<p>
<%= label_tag :name %><br />
<%= text_field_tag :name, params[:name] %>
</p>
<p>
<%= label_tag :password %><br />
<%= password_field_tag :password %>
</p>
<p class="button"><%= submit_tag "Log in" %></p>
<% end %>
when i go on url /backend im redirected to /backend/login, thats right
when i enter good login or bad login nothing happened and NO flashes appears thats strange ?
from webserver console output, i see the POST informations go through login method.. i dont know what is wrong ? thank you
edit: when i try go to URL /backend/logout im getting
Unknown action
The action 'logout' could not be found for Backend::AdminController
i really dont understand this :( im begginer
one of the conventions in rails is, that public methods in a controller are considered to be actions.
if you want to write methods for before_filter etc, make them private or protected so that rails will not expose them as actions.
on the flipside, you are not able to define actions as private.
I am trying to submit a form via remote: true in rails 3 and for some reason when I look at the response in the browser I only see the raw response instead of the JavaScript being interpreted.
Form:
<%= form_for #entry, url: contest_entries_path, remote: true, html: {id: "contest_form"} do |f| %>
Controller:
class ContestEntriesController < ApplicationController
respond_to :html, :js
def index
#entry = ContestEntry.new
#entry.build_school
respond_with #entry
end
def create
#entry = ContestEntry.new(params[:contest_entry])
respond_with #entry
end
end
Create.js.erb:
<% unless #entry.errors.any? %>
<% if #entry.parent? %>
$('body').find('#parents_message').show();
<% else %>
$('body').find('#falculty_message').show();
<% end %>
<% end %>
The response in the browser is the raw JavaScript response
am trying to confirm a user account without using the built in devise confirmations controller but i happen to get the following error "uninitialized constant Confirmations Controller". Below is my confirmations controller class.
class ConfirmationsController < Devise::ConfirmationsController
def show
#user = User.find_by_confirmation_token(params[:confirmation_token])
if !#user.present?
render_with_scope :new
end
end
def confirm_account
#user = User.find(params[:user][:confirmation_token])
if #user.update_attributes(params[:user]) and #user.has_password?
#user = User.confirm_by_token(#user.confirmation_token)
flash[:notice] = "Hi " + #user.first_name + " your email has been verified. You can now start shopping and recommending other users to your supplier networks."
redirect_to #user
else
render :action => "show"
end
end
end
And in my routes.rb file i have the following:
devise_for :users, :controllers => { :confirmations => "confirmations" } do
match "confirm_account", :to => "confirmations#confirm_account"
end
And finally i have the following partial:
<p>Welcome <%= #user.first_name %>,</p><br/>
<%= form_for(resource, :url => confirm_account_path) do |f| %>
<%= f.label :email %>
<%= #user.email %>
<%= f.hidden_field :confirmation_token %>
<%= f.submit 'Confirm Account' %>
<p>Thank you for joining. Before you can purchase any item from your supplier or shared network, you will need to confirm your account first. Please follow the link below in order to confirm your account.</p>
<p><%= link_to 'Confirm my account', confirmation_url(#resource, :confirmation_token => #resource.confirmation_token) %></p><br/>
<p>Yours faithfully.</p>
<%end%>
Devise is can be easily modified for your needs. Here is a similar topic, which may be helpful for you:
Override devise registrations controller
I have a project that contains projects that have todos that have tasks. When I try to create a new task, I get this error when I submit:
No route matches [POST] "/projects/1/todos/19/tasks/new"
Here is my form:
<%= form_for [#todo, #todo.tasks.new], :url => new_project_todo_task_path(#project, #todo) do |f| %>
<div class="field">
<%= f.label :description, "Description" %><br />
<%= f.text_area :description %>
</div>
<div class="actions">
<%= f.submit %> or <%= link_to "Cancel", "#", :id => "cancel_new_task_link" %>
</div>
<% end %>
Here is my controller:
class TasksController < ApplicationController
before_filter :authenticated?
before_filter :get_project_and_todo
respond_to :html, :xml, :json, :js
def new
#task = #todo.tasks.new
end
def create
#task = #todo.tasks.new(params[:task])
if #task.save
respond_with #todo, :location => project_todo_path(#project, #todo)
else
render "new"
end
end
private
def get_project_and_todo
#project = Project.find(params[:project_id])
#todo = #project.todos.find(params[:todo_id])
end
end
Here are my routes:
resources :projects do
resources :todos do
resources :tasks
end
end
Thanks
Your URL should not be new_project_todo_task_path(#project, #todo). You don't need to specify the URL here as Rails will imply it from the parameters passed in to form_for.
If the final object is a new object and not persisted in the database then it will make a POST request to, in this case, /projects/:project_id/todos. You're declaring in your example that you want to make a POST request to /projects/:project_id/todos/new, for which there is no POST route and that is why it's failing.
