skycocker / passwords_controller.rb
Created Jul 2, 2018
Add Location header clone for Alamofire + devise_token_auth password reset flow
View passwords_controller.rb
class Auth::PasswordsController < DeviseTokenAuth::PasswordsController
def edit

# Alamofire tends to ignore Location header in .allHeaderFields, blindly following its contents instead
# so we add a new header with the same value
# in order to parse it in mobile app
response.headers['Alamofire-Location'] = response.headers['Location']
