What's this?

check_if_method_has_arguments!(method_name, args) private

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 and the args passed into that method as an input. For example:

def references(*args)

check_if_method_has_arguments!("references", args)
...

end
