Rails 4未知格式错误

标签： ruby-on-rails ruby

我试图创建一个用户，但是当我提交它时，我收到错误。我将json设置为用户控制器和我的路由中的默认格式，但是我仍然遇到此错误。我正在运行Rails 4.2.2和ruby 2.2.1 

ActionController::UnknownFormat (ActionController::UnknownFormat):


Users Controller 

class Api::V1::UsersController < ApplicationController
  respond_to :json

  def show
    respond_with User.find(params[:id])
  end
  def create
    user = User.new(user_params)
    if user.save
      render json: user, status: 201, location: [:api, user]
    else
      render json: { errors: user.errors }, status: 422
    end
  end
  def update
    user = User.find(params[:id])

    if user.update(user_params)
        render json: user, status: 200, location: [:api, user]
    else
        render json: { errors: user.errors }, status: 422
    end
  end
  def destroy
    user = User.find(params[:id])
    user.destroy
    head 204
  end

  private

    def user_params
      params.require(:user).permit(:email, :password, :password_confirmation)
    end
end

路线

require 'api_constraints'

Rails.application.routes.draw do
  devise_for :users
  namespace :api, defaults: { format: :json },
                              constraints: { subdomain: 'api' }, path: '/'  do
    scope module: :v1,
              constraints: ApiConstraints.new(version: 1, default: true) do
      resources :users, :only => [:show, :create, :update, :destroy]
    end
  end
end
