ScopeGroup

ScopeGroup is a Ruby On Rails plugin providing dynamic named_scope grouping.

You can aggregate a group of named scope together during runtime and run them together only when methods like ‘find’, ‘count’, ‘average’, etc are called.

Install

  script/plugin install git://github.com/robin/scopegroup.git

Example

Suppose Post is an activerecord model:

  scope_group = ScopeGroup.new Post
  scope_group.named_scope1
  scope_group.named_scope2(1)
  scope_group.find(:all)

is equivalent to:

  Post.named_scope1.named_scope2(1)

You can also use append_scope as:

  scope_group = ScopeGroup.new Post
  scope_group.append_scope :named_scope1
  scope_group.append_scope :named_scope2, 1
  scope_group.count

, which is equivalent to:

  Post.named_scope1.named_scope2(1).count
