What are some common methods in Django ORM models?

Django ORM provides several methods for querying and manipulating data. Common methods include create(), get(), filter(), exclude(), and update().

Can you explain how the filter() method works?

Sure! The filter() method is used to retrieve records that match certain criteria. For example, ModelName.objects.filter(field_name=value) returns all records where field_name equals value.

What about the get() method? How is it different from filter()?

The get() method retrieves a single record that matches the criteria. If no records are found or if multiple records match, it raises an exception. In contrast, filter() returns a queryset, which can contain multiple records.

Are there any methods for updating records?

Yes! You can use the update() method to modify existing records. For example, ModelName.objects.filter(condition).update(field_name=new_value) updates all records that match the condition.
