I get a warning when running reek on a Rails project:
[36]:ArborReloaded::UserStoryService#destroy_stories has approx 8 statements (TooManyStatements)
Here's the method:
def destroy_stories(project_id, user_stories)
errors = []
@project = Project.find(project_id)
user_stories.each do |current_user_story_id|
unless @project.user_stories.find(current_user_story_id).destroy
errors.push("Error destroying user_story: #{current_user_story_id}")
end
end
if errors.compact.length == 0
@common_response.success = true
else
@common_response.success = false
@common_response.errors = errors
end
@common_response
end
How can this method be minimized?
First, I find that class and method size are useful for finding code that might need refactoring, but sometimes you really do need a long class or method. And there is always a way to make your code shorter to get around such limits, but that might make it less readable. So I disable that type of inspection when using static analysis tools.
Also, it's unclear to me why you'd expect to have an error when deleting a story, or who benefits from an error message that just includes the ID and nothing about what error occurred.
That said, I'd write that method like this, to reduce the explicit local state and to better separate concerns:
You can see how taking some care in your framework can save a lot of noise in your components.
