Overview

A queryable is any object that needs queryable’s dsl injected into it to build MongoDB queries. For example, a Mongoid::Criteria is an Queryable.

Examples:

Include queryable functionality.

class Criteria
  include Queryable
end

Instance Method Details

#==(other) ⇒ true | false

Is this queryable equal to another object? Is true if the selector and options are equal.

Examples:

Are the objects equal?

queryable == criteria

Parameters:

  • other (Object) —

    The object to compare against.

Returns:

  • (true | false) —

    If the objects are equal.

def ==(other)
  return false unless other.is_a?(Queryable)
  selector == other.selector && options == other.options
end

#initialize(aliases = {}, serializers = {}, associations = {}, aliased_associations = {}) {|_self| ... } ⇒ Object

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Initialize the new queryable. Will yield itself to the block if a block is provided for objects that need additional behavior.

Examples:

Initialize the queryable.

Queryable.new

Parameters:

  • aliases (Hash) (defaults to: {}) —

    The optional field aliases.

  • serializers (Hash) (defaults to: {}) —

    The optional field serializers.

  • associations (Hash) (defaults to: {}) —

    The optional associations.

  • aliased_associations (Hash) (defaults to: {}) —

    The optional aliased associations.

  • driver (Symbol) —

    The driver being used.

Yields:

  • (_self)
