[Consulting](https://bitscorp.co)
It's a utility library for enabling functionallity like login as button for
admin.
If you have multi users application and sometimes you want to test functionally
using login of existing user without requesting the password, define login as
button with url helper and use it.
## Installation
Add this line to your application's Gemfile:
gem 'devise_masquerade'
And then execute:
$ bundle
## Usage
In the view you can use url helper for defining link:
```ruby
= link_to "Login As", masquerade_path(user)
```
`masquerade_path` would create specific `/masquerade` path with query params `masquerade`(key) and `masqueraded_resource_class` to know
which model to choose to search and sign in by masquerade key.
In the model you'll need to add the parameter :masqueradable to the existing comma separated values in the devise method:
```ruby
devise :invitable, :confirmable, :database_authenticatable, :registerable, :masqueradable
```
Add into your `application_controller.rb` if you want to have custom way on sign in by using masquerade token otherwise you can still
use only `masquerade_path` in your view to generate temporary token and link to make `Login As`:
```ruby
before_action :masquerade_user!
```
or
```ruby
before_action :masquerade!
```
`masquerade!` is generic way in case if you want to support multiple models on masquerade.
Instead of user you can use your resource name admin, student or another names.
If you want to back to the owner of masquerade action user you could use
helpers:
```ruby
user_masquerade? # current user was masqueraded by owner?
= link_to "Reverse masquerade", back_masquerade_path(current_user)
```
## Custom controller for adding cancan for authorization
```ruby
class Admin::MasqueradesController < Devise::MasqueradesController
def show
super
end
protected
def masquerade_authorize!
authorize!(:masquerade, User)
end
# or you can define:
# def masquerade_authorized?
# (true/false)
# end
end
```
## Alternatively using Pundit
Controller:
```ruby
class Admin::MasqueradesController < Devise::MasqueradesController
protected
def masquerade_authorize!
authorize(User, :masquerade?) unless params[:action] == 'back'
end
end
```
In your view:
```erb
<% if policy(@user).masquerade? %>
<%= link_to "Login as", masquerade_path(@user) %>
<% end %>
```
## Custom url redirect after masquerade:
```ruby
class Admin::MasqueradesController < Devise::MasqueradesController
protected
def after_masquerade_path_for(resource)
"/custom_url"
end
end
```
## Custom url redirect after finishing masquerade:
```ruby
class Admin::MasqueradesController < Devise::MasqueradesController
protected
def after_back_masquerade_path_for(resource)
"/custom_url"
end
end
```
## Overriding the finder
For example, if you use FriendlyId:
```ruby
class Admin::MasqueradesController < Devise::MasqueradesController
protected
def find_masqueradable_resource
masqueraded_resource_class.friendly.find(params[:id])
end
end
```
#### Dont forget to update your Devise routes to point at your Custom Authorization Controller
in `routes.rb`:
```ruby
devise_for :users, controllers: { masquerades: "admin/masquerades" }
```
## You can redefine few options:
```ruby
Devise.masquerade_param = 'masquerade'
Devise.masquerade_expires_in = 10.seconds
Devise.masquerade_key_size = 16 # size of the generate by SecureRandom.urlsafe_base64
Devise.masquerade_bypass_warden_callback = false
Devise.masquerade_routes_back = false # if true, route back to the page the user was on via redirect_back
Devise.masquerading_resource_class = AdminUser
# optional: Devise.masquerading_resource_class_name = 'AdminUser'
# optional, default: masquerading_resource_class.model_name.param_key
Devise.masquerading_resource_name = :admin_user
Devise.masqueraded_resource_class = User
# optional: Devise.masqueraded_resource_class_name = 'User'
# optional, default: masqueraded_resource_class.model_name.param_key
Devise.masqueraded_resource_name = :user
# optional, default: masquerade_storage_method = :session
# values: :session, :cache
Devise.masquerade_storage_method = :session
```
## Demo project
cd spec/dummy
rake db:setup
rails server
And check http://localhost:3000/, use for login [email protected] and
'password'
## Troubleshooting
Are you working in development mode and wondering why masquerade attempts result in a [Receiving "You are already signed in" flash[:error]](https://github.com/oivoodoo/devise_masquerade/issues/58) message? `Filter chain halted as :require_no_authentication rendered or redirected` showing up in your logfile? Do you find that your `user_masquerade?` method is always returning false? Chances are that you need to enable caching:
rails dev:cache
This is a one-time operation, so you can set it and forget it. Should you ever need to disable caching in development, you can re-run the command as required.
