Accepts a hash of SQL conditions and replaces those attributes that correspond to a composed_of relationship with their expanded aggregate attribute values. Given:

    class Person < ActiveRecord::Base
      composed_of :address, :class_name => "Address",
        :mapping => [%w(address_street street), %w(address_city city)]
    end

Then:

    { :address => Address.new("813 abc st.", "chicago") }
      # => { :address_street => "813 abc st.", :address_city => "chicago" }

Alias for sanitize_sql

Alias for sanitize_sql_for_conditions

Accepts an array of conditions. The array has each value sanitized and interpolated into the SQL statement.

  ["name='%s' and group_id='%s'", "foo'bar", 4]  returns  "name='foo''bar' and group_id='4'"

Accepts an array, hash, or string of SQL conditions and sanitizes them into a valid SQL fragment for a SET clause.

  { :name => nil, :group_id => 4 }  returns "name = NULL , group_id='4'"

Accepts an array, hash, or string of SQL conditions and sanitizes them into a valid SQL fragment for a WHERE clause.

  ["name='%s' and group_id='%s'", "foo'bar", 4]  returns  "name='foo''bar' and group_id='4'"
  { :name => "foo'bar", :group_id => 4 }  returns "name='foo''bar' and group_id='4'"
  "name='foo''bar' and group_id='4'" returns "name='foo''bar' and group_id='4'"

Alias for sanitize_sql_hash_for_conditions

Sanitizes a hash of attribute/value pairs into SQL conditions for a SET clause.

  { :status => nil, :group_id => 1 }
    # => "status = NULL , group_id = 1"

Sanitizes a hash of attribute/value pairs into SQL conditions for a WHERE clause.

  { :name => "foo'bar", :group_id => 4 }
    # => "name='foo''bar' and group_id= 4"
  { :status => nil, :group_id => [1,2,3] }
    # => "status IS NULL and group_id IN (1,2,3)"
  { :age => 13..18 }
    # => "age BETWEEN 13 AND 18"
  { 'other_records.id' => 7 }
    # => "`other_records`.`id` = 7"
  { :other_records => { :id => 7 } }
    # => "`other_records`.`id` = 7"

And for value objects on a composed_of relationship:

  { :address => Address.new("123 abc st.", "chicago") }
    # => "address_street='123 abc st.' and address_city='chicago'"
