Copy the Code code as follows: Class Elitemajormodel extends relationmodel{
Protected $_link=array (
' Elitestudent ' =>array (
' Mapping_type ' =>has_many,//Easy to mistake: here in Has_many often add ' easy to write ' Has_many ', resulting in an error.
' Class_name ' = ' elitestudent ',
' Foreign_key ' = ' mid ',
' Mapping_name ' = ' studentslist ',
),
);
}
