expand_hash_conditions_for_aggregates(attrs)

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" }

sanitize_conditions(condition, table_name = self.table_name)
sanitize_sql(condition, table_name = self.table_name)
Also aliased as: sanitize_conditions
sanitize_sql_array(ary)

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'"

sanitize_sql_for_assignment(assignments)

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'"

  end
end
sanitize_sql_for_conditions(condition, table_name = self.table_name)

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'"

sanitize_sql_hash(attrs, default_table_name = self.table_name)
sanitize_sql_hash_for_assignment(attrs)

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

  # => "status = NULL , group_id = 1"

    "#{connection.quote_column_name(attr)} = #{quote_bound_value(value)}"
  end.join(', ')
end
sanitize_sql_hash_for_conditions(attrs, default_table_name = self.table_name)

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'"
