Functional Testing Nested Resources

Rails
1

I understand that in order to functional test a nested resource, you
need
to pass the id of the parent resource. I am having a problem testing
the
‘edit’ action on the nested resource.

Here is the failing test.

test “should get edit” do
get :edit, id: capability_types(:one).id, capability_category_id:
capability_categories(:one).id
assert_response :success
end

id: capability_types(:one).id is passing the id from the
capability_types
fixture. I am setting the capability_category_id from the
capability_categories fixture.

I am getting this error message.

Couldn’t find CapabilityType with id=980190962 [WHERE
“capability_types”.“capability_category_id” = $1]
Exception `ActiveRecord::RecordNotFound’

#fixtures
capability_types.yml
one:
name: MyString
capability_category_id: 1

two:
name: MyString
capability_category_id: 1

capability_categories.yml
one:
name: MyString

two:
name: MyString

‘edit’ action in the controller
def edit
@capability_type =
@capability_category.capability_types.find(params[:id])
end

I am using Rails 4 and have a before_action defined to set_the
capability_category.

before_action :set_capability_category

def set_capability_category
@capability_category =
CapabilityCategory.find(params[:capability_category_id])
end

I can see anything that I’ve done that should not work. Any ideas?
would
be greatly appreciated.

I managed to get this to work. I used the fixture name instead of the
rigid
foreign key id in the capability_test.yml fixture.

Thus,

#fixtures
capability_types.yml
one:
name: MyString
capability_category: one

two:
name: MyString
capability_category: one

Glad you got it going, but I just wanted to recommend you take a serious
look at move away from fixtures to factories instead.

And I suggest you do your best to minimize the use of
factories/fixtures.
In functional tests, you’ll want to limit your use of factories or
fixtures
only to the setup step for your functional tests.

This way you’re only putting your application data in a specific state
before you exercise the system.

I’m assuming these are also end-to-end tests as well.
