# Finders
|
|
|
|
These types of classes are responsible for retrieving collection items based on different conditions.
|
|
They prevent lookup methods in models like this:
|
|
|
|
|
|
```ruby
|
|
class Project < ApplicationRecord
|
|
def issues_for_user_filtered_by(user, filter)
|
|
# A lot of logic not related to project model itself
|
|
end
|
|
end
|
|
|
|
issues = project.issues_for_user_filtered_by(user, params)
|
|
```
|
|
|
|
The GitLab approach is to use a Finder:
|
|
|
|
```ruby
|
|
issues = IssuesFinder.new(project, user, filter).execute
|
|
```
|
|
|
|
It will help keep models thinner.
