Chainable methods on Model managers

Project description

Allows chaining of custom model Manager methods, without jumping through QuerySet hoops.

Installing

Simply install the package using pip:

pip install django-chainable-manager

Using

Create a Manager that extends chainablemanager.ChainableManager:

from django.db import models
from chainablemanager.manager import ChainableManager

class PostManager(ChainableManager):
    class QuerySetMixin(object):
        def published(self):
            return self.filter(publish_date__gte=datetime.date.today())

        def written_by(self, user):
            return self.filter(author=user)

class Post(models.Model):
    title = models.CharField(max_length=255)
    content = models.TextField()
    publish_date = models.DateField()
    author = models.ForeignKey('auth.User')

    objects = PostManager()

Now use it where ever you need it:

from .models import Post

my_published_posts = Post.objects.written_by(request.user).published()
