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
