Class has no objects member

Question

def index(request):
   latest_question_list = Question.objects.all().order_by('-pub_date')[:5]
   template = loader.get_template('polls/index.html')
   context = {'latest_question_list':latest_question_list}
   return HttpResponse(template.render(context, request))

The first line of that function gets an error on Question.objects.all():

E1101: Class 'Question' has no 'objects' member

I'm following the Django documentation tutorial and they have the same code up and running.

I have tried calling an instance.

Question = new Question()
and using MyModel.objects.all()

Also my models.py code for that class is this...

class Question(models.Model):
    question_text = models.CharField(max_length = 200)
    pub_date = models.DateTimeField('date published') 

    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)

    def __str__(self):
        return self.question_text

To no avail I still have this error.

I have read about pylint and ran this...

pylint --load-plugins pylint_django

Which didn't help, even tho the github readme file says...

Prevents warnings about Django-generated attributes such as Model.objects or Views.request.

I ran the command within my virtualenv, and yet nothing.

So any help would be great.

I'm assuming your models.py file has indents following the class and imports models at the top like in the tutorial? — Gavin Achtemeier, Jul 17 '17 at 03:04
Do you have any other thing named `Question` in your source code? — Rohan, Jul 17 '17 at 03:43
have you made migartions properly? and can you post the whole view file? — Exprator, Jul 17 '17 at 04:30
just change this line and migrate and then run the view once, return self.pub_date >= timezone.now() - datetime.timedelta(days=1) to return self.pub_date >= datetime.now() - datetime.timedelta(days=1) — Exprator, Jul 17 '17 at 04:31
@buuencrypted Please install pylint-django and restart your ide while check it. That will prevent that warning. — Raja Simon, Jul 17 '17 at 05:15
Judging by the fact you're willing to define an instance with the class name (`Question = new Question()`), I presume you've made the same mistake elsewhere, don't shadow class names with instances — Sayse, Jul 17 '17 at 06:20
For me what solved the issue was creating a `Manager` instance in the `models.py` file. Refer to [django documentation](https://docs.djangoproject.com/en/2.0/ref/models/class/) for more info. — Ikraj mohammad, Jun 19 '18 at 19:53

Install pylint-django using pip as follows

pip install pylint-django

Then in Visual Studio Code goto: User Settings (Ctrl + , or File > Preferences > Settings if available ) Put in the following (please note the curly braces which are required for custom user settings in VSC):

{"python.linting.pylintArgs": [
     "--load-plugins=pylint_django"
],}

Excellent! I'd also point out that you can put the plugin option in a `.pylintrc` file like so: `load-plugins=pylint_django` And that way it will be picked up by the CLI as well, so it would work in a continuous integration setting. – sibnerian Jul 07 '18 at 17:36

@VishnuSharma by adding the configuration. **it disables the default values of Pylint**, so you should add default values manually. You can do so as followed: `{"python.linting.pylintArgs": [ "--load-plugins=pylint_django", "--disable=all", "--enable=F,E,unreachable,duplicate-key,unnecessary-semicolon,global-variable-not-assigned,unused-variable,binary-op-exception,bad-format-string,anomalous-backslash-in-string,bad-open-mode" ]}` [for more info](https://code.visualstudio.com/docs/python/linting#_commandline-arguments-and-configuration-files) – Oded .S Oct 06 '20 at 17:43

@tieuminh2510's answer is perfect. But in newer versions of VSC you will not find the option to edit or paste that command in User Settings.

For newer versions, add the code in the following steps:

Press ctrl shift p to open the the Command Palette.
Now in Command Palette type Preferences: Configure Language Specific Settings.
Select Python.
Add these lines inside the first curly braces:

    "python.linting.pylintArgs": [
            "--load-plugins=pylint_django",
        ]

Make sure that pylint-django is also installed.

The settings.json available for python language should look like the below:

I've tried all possible solutions offered but unluckly my vscode settings won't changed its linter path. So, I tride to explore vscode settings in settings > User Settings > python. Find Linting: Pylint Path and change it to "pylint_django". Don't forget to change the linter to "pylint_django" at settings > User Settings > python configuration from "pyLint" to "pylint_django".

Heres the answer. Gotten from my reddit post... https://www.reddit.com/r/django/comments/6nq0bq/class_question_has_no_objects_member/

That's not an error, it's just a warning from VSC. Django adds that property dynamically to all model classes (it uses a lot of magic under the hood), so the IDE doesn't know about it by looking at the class declaration, so it warns you about a possible error (it's not). objects is in fact a Manager instance that helps with querying the DB. If you really want to get rid of that warning you could go to all your models and add objects = models.Manager() Now, VSC will see the objects declared and will not complain about it again.

`objects = models.Manager()` in the models class did it for me in VS Code. Thanks. — Mallory-Erik, Jul 24 '17 at 02:25

UPDATE FOR VS CODE 1.40.0

After doing:

$ pip install pylint-django

Follow this link: https://code.visualstudio.com/docs/python/linting#_default-pylint-rules

Notice that the way to make pylint have into account pylint-django is by specifying:

"python.linting.pylintArgs": ["--load-plugins", "pylint_django"]

in the settings.json of VS Code.

But after that, you will notice a lot of new linting errors. Then, read what it said here:

These arguments are passed whenever the python.linting.pylintUseMinimalCheckers is set to true (the default). If you specify a value in pylintArgs or use a Pylint configuration file (see the next section), then pylintUseMinimalCheckers is implicitly set to false.

What I have done is creating a .pylintrc file as described in the link, and then, configured the following parameters inside the file (leaving the rest of the file untouched):

load-plugins=pylint_django

disable=all

enable=F,E,unreachable,duplicate-key,unnecessary-semicolon,global-variable-not-assigned,unused-variable,binary-op-exception,bad-format-string,anomalous-backslash-in-string,bad-open-mode

Now pylint works as expected.

Instead of creating a separate .pylintrc file, you can get the same effect by doing this in your settings.json: { "python.linting.pylintArgs": [ "--load-plugins=pylint_django", "--disable=all", "--enable=F,E,unreachable,duplicate-key,unnecessary-semicolon,global-variable-not-assigned,unused-variable,binary-op-exception,bad-format-string,anomalous-backslash-in-string,bad-open-mode" ] } — sql_knievel, May 02 '20 at 15:45

You can change the linter for Python extension for Visual Studio Code.

In VS open the Command Palette Ctrl+Shift+P and type in one of the following commands:

Python: Select Linter

when you select a linter it will be installed. I tried flake8 and it seems issue resolved for me.

Just adding on to what @Mallory-Erik said: You can place objects = models.Manager() it in the modals:

class Question(models.Model):
    # ...
    def was_published_recently(self):
        return self.pub_date >= timezone.now() - datetime.timedelta(days=1)
    # ...
    def __str__(self):
        return self.question_text
    question_text = models.CharField(max_length = 200)
    pub_date = models.DateTimeField('date published')
    objects = models.Manager()

That's the only solution which works for me with Django 3 and Python 3.8. Thanks mate. — Andrea, Aug 01 '20 at 09:09

How about suppressing errors on each line specific to each error?

Something like this: https://pylint.readthedocs.io/en/latest/user_guide/message-control.html

Error: [pylint] Class 'class_name' has no 'member_name' member It can be suppressed on that line by:

  # pylint: disable=no-member

By doing Question = new Question() (I assume the new is a typo) you are overwriting the Question model with an intance of Question. Like Sayse said in the comments: don't use the same name for your variable as the name of the model. So change it to something like my_question = Question().
