Why Should I Use This?

Django ORM is great and easy to use but can easily hide some very back behaviours. Just by calling a property here and there you can cascade a chain of hundreds of queries hidden behind the easy-to-use model abstractions. This lib prevents it to happen by locking the ORM not allowing it to perform the queries by raising an exception.

How To Install

• Install with

pip install django-query-blocker

How To Use

• It can be used as a context or decorator

Context

from query_blocker import block_extra_queries

my_object = MyModel.objects.first()
print(my_object)  # works fine
with block_extra_queries:
    print(obj.foreign_key_obj) # will raise a NoExtraQueryException

Decorator

from query_blocker import block_extra_queries

@block_extra_queries
def my_method(obj):
    print(obj.foreign_key_obj)

my_object = MyModel.objects.first()
print(my_object)  # works fine
my_method(my_object)  # will raise a NoExtraQueryException
