Overview
Filter by Field
ModelItem::filter('article_category_id')
Creates filter by article_category_id field. You can add ?article_category_id=5 parameter to the query to filter by field.
Filter Alias
ModelItem::filter('article_category_id')->as('category')
Creates filter by article_category_id field, but searches for category parameter in query. You can add ?category=5 parameter to the query to filter by field.
Apply Scope
ModelItem::filter('withEmptyCategories')->scope('withoutCategories')
This will apply scope withoutCategories (scopeWithoutCategories($query) in model) to the query.
Override Query Parameter
ModelItem::filter('title')->as('todo')->value('TODO category')
Creates filter by title field with todo alias. It ignores parameter value from query and overrides it with 'TODO category'.
Important: query parameter must have value. You can`t access this filter using categories?todo, but categories?todo=1 or categories?todo=something_else will work.
