As per the docs
You still need to fully define the field inside the array field
question_array = ArrayField(models.IntegerField(null=True, blank=True), blank=True,)

models.IntegerField is a function not a property, so you will be required to call it like a function. () at the end
question_array = ArrayField(models.IntegerField(blank=True), blank=True,)

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.

Does anyone know what might be causing this error? I am still very new to coding and am using vscode if that helps at all. Thanks in advance for your help!
In serializer.py Try:
from rest_framework import serializers
Django-rest framework doesn't have any API called serializer.
More: https://www.django-rest-framework.org/api-guide/serializers/
import should be

Connecting Models from different Apps - Django

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:

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:

Your import should be from data.models import Sentence instead of from myprojname.data import Sentence.
