How can I use exclude in Django filters?

How can I use exclude in Django filters?

You can use the exclude() method in Django's QuerySet to filter out specific records. For example, MyModel.objects.exclude(field_name=value) will return all records except those where field_name equals value.

Can I chain exclude with other filters?

Yes, you can chain exclude() with other filters. For instance, MyModel.objects.filter(condition).exclude(field_name=value) will first filter the records and then exclude the specified ones.

What if I want to exclude multiple values?

You can exclude multiple values by using the Q object. For example: MyModel.objects.exclude(Q(field_name=value1) | Q(field_name=value2)).

Are there any performance considerations when using exclude?

Yes, using exclude() can impact performance, especially with large datasets. It's best to analyze your queries and optimize them when necessary.
