I'm trying to run a django code an imx6 yocto build that i made. The basic example went fine and smooth. So i decided to run my own django production from a project im working and i get the following:

SyntaxError: invalid syntax
The code in models.py is the following:
from django.db import models
# Create your models here.
class Initial_config(models.Model):
#complement = models.CharField(max_length=30,null=True)
cloud_interval = models.IntegerField()
device_interval = models.IntegerField()
class Meta:
verbose_name = 'config'
verbose_name_plural = 'configs'
def __str__(self):
return f'{self.cloud_interval} foi cadastrado com sucesso!'
I tried to change the ' to " remove the {self.cloud_interval}, but none of them was sucessful.
Why this happens? How to fix it?
f-strings can only be used from Python 3.6 onwards.
If you want to remain with Python 3.5, you can change your code to:
def __str__(self):
return '%s foi cadastrado com sucesso!' % self.cloud_interval
That said, Python 3.5 is no longer officially supported; upgrading to 3.6 or above is highly recommended. See https://endoflife.date/python for more.

I am learning this Django Framework from this summer. I have get the error <TypeError: 'NoneType' object is not callable>. I am trying to narrow down the problem. However, after I have delete a lot of code, I still cannot figure this out from the most simple code. My code is showed as below.

what I have down
I have search the web of Django & Python and dozens of Questions on stack overflow.
I have realize that the most common solution is to remove the ().
However, I do not call the func. anywhere.
Therefore,I have raised this question to search for is there some mistake I do not understand about. Thanks for any advice/suggestion that help me to improve.
The error is from the #admin.site.register(Car)
this is because it returns None and wrapping CarAdmin with None is equivalent to doing CarAdmin = None(CarAdmin).
The solution is to use #admin.register(Car) instead

My project is actually a single-page website, so it is not a big hassle to remove django-hvad and use something else. That is my question therefore, what steps are better to take:
(1) try to use another "app" for model translation, as in:
https://djangopackages.org/grids/g/model-translation/
(however, as I see, only one package supports Django1.10 there).
(2) Or maybe Django has a native model translation option which I should use.
(3) another option
The strange thing also is that https://django-hvad.readthedocs.io/en/latest/index.html indicates that django1.9 is the last supported version, but in GitHub page https://github.com/kristianoellegaard/django-hvad it is written that django 1.10 as well as django 1.11 are supported.
Please indicate what more information is needed, I will try to provide.
My pip freeze output:
Django==1.10

I wonder why I get this error, and what to do about it. I'm using Django version 1.11.
You can't do what you're trying to do with a proxy model. Luckily, Django makes it easy to extend the built-in User model: create a normal concrete model that inherits from AbstractUser, and set the AUTH_USER_MODEL setting to the name of your model.
Given that I have 4 models:
Project
User (from django.contrib.auth.models)
Sentence
Translation
My django project directories are structured as such:
\myprojname
\project
models.py
\data
models.py
The User model is independent of the Projects and Sentences models but it is linked to the Projects model through the ForeignKey:
myprojname/projects/models.py looks like this:
from django.db import models
from django.contrib.auth.models import User
class Project(models.Model):
project_id = models.AutoField(primary_key=True)
created_on = models.DateTimeField(auto_now_add=True)
updated_on = models.DateTimeField(auto_now=True)
name = models.CharField(max_length=140)
# Admin user for the particular *Project* object.
# Have the rights to write to the *Sentence* model.
owner = models.ForeignKey(User)
# Worker users that only have write access to the *Translation model.
workers = models.ForeignKey(User, blank=True)
myprojname/data/models.py looks like this:
from django.db import models
from django.contrib.auth.models import User
class Sentence(models.Model):
text = models.TextField()
translations = models.ManyToManyField('Translation', blank=True)
class Translation(models.Model):
text = models.TextField()
translator = models.ForeignKey(User)
Now the Project model isn't connected to the Sentence model.
I've tried connecting it with relative imports, i.e. in myprojname/projects/models.py, I did:
from django.db import models
from django.contrib.auth.models import User
from ..data import Sentence
class Project(models.Model):
# ...
sentences = models.ForeignKey(Sentence)
but it returned a ValueError in Python2.7:

from ..data import Sentence
ValueError: attempted relative import beyond top-level package
And when I tried to do a non-relative import in Python3:
from django.db import models
from django.contrib.auth.models import User
from myprojname.data import Sentence
class Project(models.Model):
# ...
sentences = models.ForeignKey(Sentence)
I get:

ImportError: No module named 'myprojname.data'
How do I connect the models from different apps?
Edited
When I used from data import Sentence in myprojname.project.models.py, it throws an ImportError:

from data import Sentence
ImportError: cannot import name 'Sentence'
Your import should be from data.models import Sentence instead of from myprojname.data import Sentence.
