Scopes

Also you can specify prepared query statement.

scope :query_name { where { c("some_field") > 10 } }
scope :query_with_arguments { |a, b| where { (c("f1") == a) && (c("f2").in(b) } }

As you can see arguments are next:

• scope (query) name
• block to be executed in query context (any query part could be passed: join, where, having, etc.)

Also they are chainable, so you could do:

ModelName.all
  .where { _some_field > 1 }
  .query_with_arguments("done", [1,2])
  .order(f1: :asc)
  .no_argument_query

Default model scope

To define a default model scope override .all method:

class Model < Jennifer::Mode::Base
  def self.all
    super.where { _deleted == false }
  end
end
