Instance Method Details

#find_file_in_entry(file_type, file_perma_id, entry = @entry) ⇒ Object

Instead of finding a file directly by its ID (stored in configuration hashes for example), finds the file by its usages perma_id within the scope of the revisions usages. The @entry instance variable (of type DraftEntry or PublishedEntry) must always be available in views using this helper, otherwise an exception is raised.

When testing helpers which use the RevisionFileHelper to find their respective files, you can use the UsedfileTestHelper to create the file. This will set the @entry-variable and create a file usage for the file:

image_file = create_used_file(:image_file)

This simplifies spec setup by eliminating the need to set up the entry and usages first. If you need to setup the entry explicitely, you can optionally pass it to the helper like so:

entry = PublishedEntry.new(create(:entry, :published))
image_file = create_used_file(:image_file, entry: entry)
