I have a native Rails app that uses Devise for authentication (using the token_authenticatable module). With an existing account I can successfully perform API calls in my native iOS app using JSON once I get a token.

I'd like to add the capability to create a new account via the iOS app, without using a browser. Does Devise only allow account creation via HTML?

I've looked at this post Rails/Devise - Creating new users via json request

And tried various things via CURL, including: 

$ curl -H "Content-Type: application/json" -d '{"email":"who@me.com","password":"mypass"}' -vX POST http://localhost:5000/users.json
...

enable json for devise

config.navigational_formats = ["/", :json]

and add new file

class RegistrationsController < Devise::RegistrationsController

  def create

    @user = User.create(params[:user])
    if @user.save
      render :json => {:state => {:code => 0}, :data => @user }
    else
      render :json => {:state => {:code => 1, :messages => @user.errors.full_messages} }
    end

  end
end

in routes:

  devise_for :users, :controllers => {:registrations => "registrations"}

UPDATE

Also json should look:

{"user" : {"email":"who@me.com","password":"mypass"}}

    To get this to work with HTML and JSON, I ended up with this solution: http://stackoverflow.com/questions/14447835/using-devise-to-sign-up-sign-in-and-sign-out-with-an-ios-app/14800237#14800237 – joseph.hainline Feb 10 '13 at 17:07
  • Thanks! I needed to add a private method user_params to the controller to whitelist :email and :password. I also had to disable CSRF protection as suggested [here](http://stackoverflow.com/a/10049965/313633). – Sjors Provoost Mar 06 '14 at 18:40
