154 CHAPTER 7 Basic access control
Using the following listing, create the form partial that’s referenced in this new view at
app/views/admin/users/_form.html.erb. It must contain the email and password
fields, which are the bare essentials for creating a user.
Listing 7.23 app/views/admin/users/_form.html.erb
For this form_for, you use the array form you saw earlier with [@project, @ticket],
but this time you pass in a symbol rather than a model object. Rails interprets the
symbol literally, generating a route such as admin_users_path rather than
users_path, which would normally be generated. You can also use this array syntax
with link_to and redirect_to helpers. Any symbol passed anywhere in the array is
interpreted literally.
When you run the feature once again, you’re told there’s no action called create:
And I press "Create User"
The action 'create' could not be found for Admin::UsersController
7.5.4 The create action
Let’s create that action now by using this code:
def create
@user = User.new(params[:user])
if @user.save
flash[:notice] = "User has been created."
redirect_to admin_users_path
else
flash[:alert] = "User has not been created."
render :action => "new"
end
end
With this action implemented, both scenarios inside this feature now pass:
2 scenarios (2 passed)
21 steps (21 passed)
This is another great middle point for a commit, so let’s do so now. As usual, you
should run rake cucumber:ok spec to make sure everything’s still working:
