module RevisionFileHelper
# 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)
#
# @since 15.0
# @returns UsedFile
def find_file_in_entry(file_type, file_perma_id, entry = @entry)
raise 'No entry of type PublishedEntry or DraftEntry set.' unless entry.present?
entry.find_file_by_perma_id(file_type, file_perma_id)
end
