Request spec: How to create a new user via POST request?

Question

Given the following controller:

class UsersController < ApplicationController
      include ActionController::ImplicitRender
      include ActionController::ParamsWrapper

      wrap_parameters format: :json
      # POST /users
      # POST /users.json
      def create
        #@user = User.new(params[:user])
        @user = User.new(user_params)

        if @user.save
          render json: @user, status: :created, location: @user
        else
          render json: @user.errors, status: :unprocessable_entity
        end
      end

      private

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

I am able to create a new user by sending a HTTP POST request with CURL:

curl -H "Content-Type: application/json" -d '{"name":"xyz","email":"[email protected]"}' http://myrailsapp.dev/users

How would I craft the request spec accordingly?

  # spec/requests/users_spec.rb
  describe "POST /users" do
    it "should create a new user" do

      # FILL ME IN

      expect(response).to have_http_status(200)
    end
  end

My first idea was to add the following:

post users_path, body: '{"name":"xyz","email":"[email protected]"}'

which results in a HTTP status of 400.

Actually your first comment, (which you sadly deleted) was the working answer: ` post users_path, user: {name: "Test", email: "[email protected]" }` There seems to be no need to pass the CONTENT_TYPE. — jottr, Oct 16 '14 at 21:47
because after that I found the same question, just linked that and flagged your questions as duplicity. — Tom Hert, Oct 16 '14 at 21:49

Here is your answer:

post users_path, :user => {"name":"xyz","email":"[email protected]"}, { 'CONTENT_TYPE' => 'application/json'}

I just noticed, that this results in an error: `syntax error, unexpected ':', expecting => (SyntaxError) ...post users_path, user: {"name":"xyz","email":"[email protected]...` Also see comments under my question for refernce. – jottr Oct 16 '14 at 21:50
Updated, should be fine now – Tom Hert Oct 16 '14 at 21:55
Nope. Problem remains. – jottr Oct 16 '14 at 22:18

The problem is within the headers, you need to assure it specifies JSON content!

post users_path, '{"name":"xyz","email":"[email protected]"}' , { 'CONTENT_TYPE' => 'application/json', 'ACCEPT' => 'application/json' }

Hope that works for you! Cheers, Jan
