How do I perform database queries in Django?
In Django, you can perform database queries using the ORM. For example, to retrieve all objects from a model, you can use ModelName.objects.all()
.
Can you show me how to filter results?
Sure! You can filter results using the filter()
method. For example, ModelName.objects.filter(field_name='value')
will return all objects where field_name
matches 'value'.
What about ordering the results?
You can order results using the order_by()
method. For instance, ModelName.objects.all().order_by('field_name')
will order the results by field_name
.
How can I perform a count of the results?
To count the results, you can use the count()
method. For example, ModelName.objects.filter(field_name='value').count()
will give you the number of objects that match the filter.
