How to sign in a user using Devise from a Rails co

问题:

After loading the Rails console, how should I sign in a user?

Devise provides a test helper which can be used in tests and I've tried to use in console:

>> include Devise::TestHelpers
>> helper.sign_in(User.first)

But I get:

NoMethodError: undefined method `env' for nil:NilClass

Anyway, I would like to use the real devise helper and not this test helper. Is there any way to achieve this?

回答1:

Here's one way I was able to do it:

>> ApplicationController.allow_forgery_protection = false
>> app.post('/sign_in', {"user"=>{"login"=>"login", "password"=>"password"}})

Then you can do:

 >> app.get '/some_other_path_that_only_works_if_logged_in'
 >> pp app.response.body

Here is another example which uses the csrf token, authenticates the user, and makes a POST/GET request.

# get csrf token
app.get  '/users/sign_in'
csrf_token = app.session[:_csrf_token]

# log in
app.post('/users/sign_in', {"authenticity_token"=>csrf_token, "user"=>{"email"=>"foo", "password"=>"bar"}})

# get new csrf token, as auth user
app.get ''
csrf_token = app.session[:_csrf_token]

# make a POST request
app.post '/some_request.json', {"some_value"=>"wee", "authenticity_token"=>csrf_token}

# make a GET request
app.get '/some_other_request.json'

You can add an action inside one of your controller, and use the technique explained here.

class MyController < ApplicationController
  # POST /my_controller/become {'email': '[e-mail]'}
  def become
    raise 'not in development environment' unless Rails.env == 'development'
    sign_in User.find_by_email(params[:email])
  end
end
