Devise Authentication Gem: How to Save the Logged in User Id

Devise authentication gem: How to save the logged in user id?

1. Create a migration file with a column of type integer named user_id, this is where the association will be stored. (see the migration guide for details on how to do this).

2. in your model, add: belongs_to :user (see the associations guide for more details)

3. in the controller for your model, add @your_model.user = current_user in the create action. This will do the association you're looking for. (current_user is a method provided by devise that returns the User ActiveRecord for the currently logged in user)

Note: there are more than one way of doing the actual association. I'm suggesting to do it in the controller but it could be done in the model or elsewhere.

Get current user id in devise

Replace current index action as below

def index    
   if current_user
     @sheets = current_user.time_sheets
   else
     redirect_to new_user_session_path, notice: 'You are not logged in.'
   end
end

If user is not logged in, i.e., current_user=nil then user would be redirected to login page with a flash message.

Ruby on Rails: gem devise session logged in

Try this in your User Controller:

    @user = User.new(user_params)
    @user.company_id = current_company.id
    respond_to do |format|
      if @user.save
        format.html { redirect_to @user, notice: 'User was successfully created.' }
        format.json { render :show, status: :created, location: @user }
      else
        format.html { render :new }
        format.json { render json: @user.errors, status: :unprocessable_entity }
      end
    end
  end

Rails Devise: How to access sign up page after signed in?

The way I handled the scenario of being able to create New Users if you are signed in was by generating a User controller and having new and create action methods that would save to the User model. (This was stripped from a current app I'm working on so hopefully I didn't miss anything)

user_controller.rb

def new
  @user = User.new
end

def create
  @user = User.new(params[:user])

  if @user.save
    flash[:notice] = "Successfully created User." 
    redirect_to root_path
  else
    render :action => 'new'
  end
end

views/user/new.html.erb

<%= form_for @user, :url => user_index_path do |f| %>
  <p><%= f.label :email %>
  <%= f.text_field :email %></p>

  <p><%= f.label :password  %>
  <%= f.password_field :password %></p>

  <p><%= f.label :password_confirmation  %>
  <%= f.password_field :password_confirmation %></p>

  <p><%= f.submit "Save" %></p>
<% end %>

config/routes.rb (Rails 3)

resources :user, :controller => "user"

Link to the New User page

<%= link_to 'New User', new_user_path %>

RoR Devise: Sign in with username OR email

I have found a solution for the problem. I'm not quite satisfied with it (I'd rather have a way to specify this in the initializer), but it works for now. In the user model I added the following method:

def self.find_for_database_authentication(conditions={})
  find_by(username: conditions[:email]) || find_by(email: conditions[:email])
end

As @sguha and @Chetan have pointed out, another great resource is available on the official devise wiki.
