end

#__find_args__Array

Get the array of args as arguments for a find query.

Examples:

Get the array as find args.

end

#__mongoize_object_id__Array<BSON::ObjectId>

end

#__mongoize_time__Time | ActiveSupport::TimeWithZone

Note:

Returns a local time in the default time zone.

Converts the array for storing as a time.

Examples:

Convert the array to a time.

[ 2010, 1, 1 ].__mongoize_time__
# => 2010-01-01 00:00:00 -0500

Returns:

  • (Time | ActiveSupport::TimeWithZone)

    Local time in the configured default time zone corresponding to date/time components in this array.

Since:

  • 3.0.0

#blank_criteria?false

Deprecated.

Checks whether conditions given in this array are known to be unsatisfiable, i.e., querying with this array will always return no documents.

This method used to assume that the array is the list of criteria to be used with an $and operator. This assumption is no longer made; therefore, since the interpretation of conditions in the array differs between $and, $or and $nor operators, this method now always returns false.

This method is deprecated. Mongoid now uses _mongoid_unsatisfiable_criteria? internally; this method is retained for backwards compatibility only. It always returns false.

Returns:

  • (false)

    Always false.

Since:

  • 3.1.0

end

#delete_one(object) ⇒ Object

Delete the first object in the array that is equal to the supplied object and return it. This is much faster than performing a standard delete for large arrays ince it attempt to delete multiple in the other.

Examples:

Delete the first object.

[ "1", "2", "1" ].delete_one("1")

Parameters:

  • object (Object)

    The object to delete.

Returns:

  • (Object)

    The deleted object.

Since:

  • 2.1.0

def delete_one(object)
  position = index(object)
  position ? delete_at(position) : nil
end

#mongoizeArray

Turn the object from the ruby type we deal with to a Mongo friendly type.

Examples:

Mongoize the object.

object.mongoize

Returns:

  • (Array)

    The object.

Since:

  • 3.0.0

end

#multi_arged?true, false

Is the array a set of multiple arguments in a method?

Examples:

Is this multi args?

[ 1, 2, 3 ].multi_arged?

Returns:

  • (true, false)

    If the array is multi args.

Since:

  • 3.0.0

def multi_arged?
  !first.is_a?(Hash) && first.resizable? || size > 1
end

#resizable?true

Is the object's size changable?

Examples:

Is the object resizable?

object.resizable?

Returns:

  • (true)

    true.

Since:

  • 3.0.0
