Rails%203%20In%20Action

The projects API
The error occurs because you’re attempting to call the [] method on something that
is nil, and it’s really likely that the something is the last_ticket key, which doesn’t
exist yet because the method is not defined. To define this method, open app/
models/project.rb and add this method inside the class:
def last_ticket
tickets.last
end
Why are you doing it this way? Well, respond_with doesn’t let you chain methods, and
so you’ll work around this by defining a method that calls the chain in your model.
When you run bin/rspec spec/api/v1/projects_spec.rb, this test will pass because
the last_ticket method is now defined:
1 example, 0 failures
Great! Now the show action is responding with data similar to this:
{
}
"project": {
"created_at": "[timestamp]",
"id": 1,
"name": "Ticketee",
"updated_at": "[timestamp]",
"last_ticket": {
"ticket": {
"asset_updated_at": null,
"created_at": "[timestamp]",
"description": "A ticket, nothing more.",
"id": 1,
"project_id": 1,
"state_id": null,
"title": "A ticket, nothing more.",
"updated_at": "[timestamp]",
"user_id": 2
}
}
}
How goes the rest of your API? Let’s find out with a quick run of rake spec:
40 examples, 0 failures, 19 pending
Ok, that’s good to see, time to make a commit:
git add .
git commit -m "Added API action for a single project with last ticket"
git push
Back in the main part of the application, you’ve got permissions on users that restrict
which projects they can see. Currently in the API there is no such restriction, and so
you need to add one to bring it in line with how the application behaves.
