check_if_method_has_arguments!

Checks to make sure that the arguments are not blank. Note that if some blank-like object were initially passed into the query method, then this method will not raise an error.

Example:

Post.references()   # raises an error
Post.references([]) # does not raise an error

This particular method should be called with a method_name (__callee__) and the args passed into that method as an input. For example:

def references(*args)

check_if_method_has_arguments!(__callee__, args)
...
