Editing projects
If you run bin/cucumber features/editing_projects.feature again, it now
complains about the missing edit action:
The action 'edit' could not be found for ProjectsController
You should now define this action in your ProjectsController, underneath the show
action, as in the following listing.
Listing 4.7 app/controllers/projects_controller.rb
def edit
@project = Project.find(params[:id])
end
As you can see, this action works in an identical fashion to the show action, where the
ID for the resource is automatically passed as params[:id]. Let’s work on DRYing 3 this
up once you’re done with this controller. When you run feature again, you’re told that
the edit view is missing:
Given I am on the homepage
Missing template projects/edit, application/edit
with {:handlers=>[:erb, :builder],
:formats=>[:html],
:locale=>[:en, :en]}.
Searched in:
* ".../ticketee/app/views"
It looks like you need to create this template. For this edit action’s template, you can
re-use the form partial (app/views/projects/_form.html.erb) you created in chapter 3
by putting the code from the following listing into app/views/projects/edit.html.erb.
Listing 4.8 app/views/projects/edit.html.erb
Edit project
When you pass a string to the render method, Rails looks up a partial in the current
directory matching the string and renders that instead. Using the partial, the next
step passes without any further intervention from you when you run bin/cucumber
features/editing_projects.feature, but the output now says it can’t find the
update action:
And I fill in "Name" with "TextMate 2 beta"
And I press "Update Project"
The action 'update' could not be found for ProjectsController
Great! It looks like the edit action is working fine, so your next step is to define the
update action.
3 As a reminder: DRY = Don’t Repeat Yourself!
