python - Unresolved attribute reference 'objects' for class '' in PyCharm

Question

I use community pycharm and the version of python is 3.6.1, django is 1.11.1. This warning has no affect on running, but I cannot use the IDE's auto complete.

Answer 1

You need to enable Django support. Go to

PyCharm -> Preferences -> Languages & Frameworks -> Django

and then check Enable Django Support

Answer 2

You can also expose the default model manager explicitly:

from django.db import models

class Foo(models.Model):
    name = models.CharField(max_length=50, primary_key=True)

    objects = models.Manager()

Answer 3

Use a Base model for all your models which exposes objects:

class BaseModel(models.Model):
    objects = models.Manager()
    class Meta:
        abstract = True


class Model1(BaseModel):
    id = models.AutoField(primary_key=True)

class Model2(BaseModel):
    id = models.AutoField(primary_key=True)

Answer 4

Python Frameworks (Django, Flask, etc.) are only supported in the Professional Edition. Check the link below for more details.

Answer 5

I found this hacky workaround using stub files:

models.py

from django.db import models


class Model(models.Model):
    class Meta:
        abstract = True

class SomeModel(Model):
    pass

models.pyi

from django.db import models

class Model:
    objects: models.Manager()

This should enable PyCharm's code completion:

This is similar to Campi's solution, but avoids the need to redeclare the default value

Answer 6

Another solution i found is putting @python_2_unicode_compatible decorator on any model. It also requires you to have a str implementation four your function

For example:

# models.py

from django.utils.encoding import python_2_unicode_compatible

@python_2_unicode_compatible
class SomeModel(models.Model):
    name = Models.CharField(max_length=255)

    def __str__(self):
         return self.name
