[Answer]-Django check if reverse lookups exist in the table

Use filter instead of get to test for existence. filter returns a queryset, which supports the exists call. get returns a model instance if one exists, or raises an exception if one does not.

Or just catch the exception, that’s OK too – and is preferable if you’re going to retrieve the object if it exists.

Depending on exactly what you’re trying to do, there may be useful helper/shortcut functions. For instance, get_object_or_404 is useful for the common situation in which you want an object based on a URL parameter and want to return a 404 for parameters that do not match a BD record. get_or_create is useful when you want to record new information if necessary, and be sure that you have an in-memory object.
