Having handled invalid form submissions, now it s time to complete the signup form by actually saving a new user (if valid) to the database First, we try to save the user; if the save succeeds, the user s information gets written to the database automatically, and we then redirect the browser to show the user s profile (together with a friendly greeting), as mocked up in Figure 88 If it fails, we simply fall back on the behavior developed in Section 82

As with the signup failure tests (Listing 86), here we use post :create to hit the create action with an HTTP POST request As in the failed creation tests from Listing 86, the first test wraps the user creation in a lambda and uses the count method to verify that the database has changed appropriately:

Here, instead of should_not change(User, :count) as in the case of a failed user creation, we have should change(User, :count)by(1), which asserts that the lambda block should change the User count by 1 The second test uses the assigns method first seen in Listing 717 to verify that the create action redirects to the newly created user s show page:
it "should redirect to the user show page" do post :create, :user => @attr responseshould redirect_to(user_path(assigns(:user))) end
8: Sign Up
This is the kind of redirect that happens on nearly every successful form submission on the web, and with RSpec s helpful syntax you don t have to know anything about the underlying HTTP response code5 The URL itself is generated using the named route user_path shown in Table 71
832 The Finished Signup Form
To get these tests to pass and thereby complete a working signup form, fill in the commented-out section in Listing 87 with a redirect, as shown in Listing 815
Listing 815 The user create action with a save and a redirect
app/controllers/users_controllerrb
class UsersController < ApplicationController def create @user = Usernew(params[:user]) if @usersave redirect_to @user else @title = "Sign up" render 'new' end end end
Note that we can omit the user_path in the redirect, writing simply redirect_to @user to redirect to the user show page, a convention we saw before with link_to in Listing 725 This syntax is nicely succinct, but unfortunately RSpec doesn t understand it, so we have to use the more verbose user_path(@user) in that case

Before submitting a valid registration in a browser, we re going to add a bit of polish common in web applications: a message that appears temporarily and then disappears upon page reload (If this is unclear now, be patient; a concrete example appears shortly) The
