Render JSON seems broken it keeps return HTML #219
Description
I am new to build Rails API from scratch (only API not web app) so I can build iOS app to connect to API. What I have an issue on my Rails API project doesn't allow me to have return JSON results, it always return HTML. Any idea what is wrong? Any suggestion appreciated. Thanks!
What I want to have a return in JSON like this:
{"code":12,"title":"User doesn't exist","status":404}
This is what I got (it returns in red header in HTML page):
Take a look at my scripts:
routes.rb (require JSON format):
Rails.application.routes.draw do
namespace :api, defaults: { format: :json } do
namespace :v1 do
resources :entries, except: [:new, :edit]
resources :users, except: [:new, :edit]
end
end
end
../app/controllers/api/v1/users_controller.rb
module Api
module V1
class UsersController < ApplicationController
before_action :set_user, only: [:show, :update, :destroy]
def show
if User.exists?(params[:id])
@user = User.find(params[:id])
render json: @user
else
render json: { code: 12, title: "User doesn't exist", status: 404 }, status: :not_found
end
.
.
.
Note: It is very strange how this show method above acting weird. Part 1 is working well to return JSON results but Part 2 returns HTML instead JSON results.
Part 1: render json: @user
Part 2: render json: { code: 12, title: "User doesn't exist", status: 404 }, status: :not_found
../app/controllers/api/v1/application_controller.rb
class ApplicationController < ActionController::API
rescue_from ActionController::ParameterMissing, with: :render_bad_request
rescue_from ActiveRecord::RecordNotSaved, :with => :access_denied
def render_bad_request(e)
render json: params, status: :bad_request
end
end
