django-saber

• django-saber

Saber provides a drop-in replacement for the Django ORM for dealing with a defined database set. All Model attributes, methods and relations will work seamlessly – faster.

Why

This library helped reduce the generation of an expensive report from 200 seconds to 1 second, by changing a prefetched queryset with an in-memory data representation.

• When you need to calculate a dataset in (near) real-time
• For read-only views

Usage

Your Django project should separate concerns; that is, separate Models (fields) and Controllers (logic). This allows Saber to use the same logic.

s ThinController(object):
 name_rhymes_with_orange(self): pass

s Thin(ThinController, models.Model):
e = models.CharField(max_length=255)

To mimic Models, provide the module that has the model Controllers. By default, memory.initialize() will load the full database into memory.

ry = Memory(controllers=['test_project.controllers'])
ry.initialize()
base = Traverse(memory.data)
base.thin.all() 
base.thin[0].name
base.thin[0].name_rhymes_with_orange()
