问题
I know there is a lot of question about that but I can't find an answer for my case.
So, I build a Rails 4 API, I try to create a User with a post JSON request.
Here some pieces of my code :
user.rb :
class User < ActiveRecord::Base
acts_as_token_authenticatable
has_secure_password
belongs_to :current_position, :class_name => "Position", foreign_key: "position_current_id"
has_many :positions
searchkick locations: ["location"]
def search_data
attributes.merge location: [current_position.latitude, current_position.longitude]
end
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
application_controller.rb
class ApplicationController < ActionController::Base
respond_to :json, :html
protect_from_forgery with: :null_session,
if: Proc.new { |c| c.request.format =~ %r{application/json} }
end
registrations_controller.rb
class Api::RegistrationsController < ApplicationController
respond_to :json
def create
user = User.new(user_params)
if user.save
render :json => {:token => user.authentication_token, :email =>user.email}, :status=>201
return
else
warden.custom_failure!
render :json =>user.errors, :status=>422
end
end
def user_params
params.require(:user).permit(:email, :password, :password_confirmation, :username)
end
end
So I try to send a request with the following params
{"user":{"email":"user5@gmail.com", "password" : "123456789", "password_confirmation" : "123456789", "username" : "toto"}}
But I get the following error :
started POST "/signup.json" for 127.0.0.1 at 2014-11-30 13:27:02 +0100
Processing by Api::RegistrationsController#create as JSON

So I'm a little bit desperate about that so if someone have some explenations to clarify me, It would be great. Thank's
EDIT :
My User schema
create_table "users", force: true do |t|
t.string "email", default: "", null: false
t.string "name"
t.datetime "created_at"
t.datetime "updated_at"
t.string "firstname"
t.string "lastname"
t.integer "age"
t.string "gender"
t.string "avatar"
t.datetime "birth"
t.string "status"
t.string "username"
t.string "password_digest"
t.string "encrypted_password"
t.string "authentication_token"
t.integer "position_current_id"
end
I also use this gem https://github.com/gonzalo-bulnes/simple_token_authentication

Ok I found the problem, I replaced :
class User < ActiveRecord::Base
acts_as_token_authenticatable
has_secure_password
belongs_to :current_position, :class_name => "Position", foreign_key: "position_current_id"
has_many :positions
searchkick locations: ["location"]
def search_data
attributes.merge location: [current_position.latitude, current_position.longitude]
end
devise :database_authenticatable, :registerable,
:recoverable, :rememberable, :trackable, :validatable
end
By this :
class User < ActiveRecord::Base
acts_as_token_authenticatable
has_secure_password
belongs_to :current_position, :class_name => "Position", foreign_key: "position_current_id"
has_many :positions
searchkick locations: ["location"]
def search_data
attributes.merge location: [current_position.latitude, current_position.longitude]
end
end
It's now working
