I have a model in one of my apps which is throwing an error when I run "python.py makemigrations signup." I have spent the last two days pouring through documentation (and Google) trying to figure out why this error is happening. Unfortunately I have come up with nothing.
What I am trying to do is include an app in my project. The app sits in the root directory of my python directory (not in a subfolder of of my project). Here is my code:
from django.db import models
class CompanyInfo(models.Model):
companyID = model.AutoField(primary_key=True)
companyName = model.CharField(max_length=100)
companyURL = model.URLField(max_length=100)
companyEmail = model.EmailField(max_length=254)
companyFEIN = model.CharField(max_length=50)
companyUsername= model.CharField(max_length=100)
companyPassword = model.CharField(max_length=100)
class CompanyContact(models.Model):
ccID = model.AutoField(primary_key=True)
ccFirstName = model.CharField(max_length=100)
ccLastName = model.CharField(max_length=100)
ccEmail = model.EmailField(max_length=254)
ccPhone = model.IntegerField(max_length=20)
The exact error that is printed to the console reads:
root#ubuntu1204:/home/humanoid# python manage.py makemigrations humanoid

It looks like you have dropped the 's' on models. You need to change your use of model to models.
For example:
companyID = model.AutoField(primary_key=True)
Needs to be:
companyID = models.AutoField(primary_key=True)
It looks like from the import it should be models (plural) and not model.

While following a Flask tutorial I stumbled around this very strange problem! While setting up the Migrate directory , after the first step of setting the flask app using set FLASK_APP=sql1.py, when I ran this command flask db init I got this error:

I'm getting the exact same error while running my .py script also,here's the script:
from flask import Flask
import os
from flask_sqlalchemy import SQLAlchemy
from flask_migrate import Migrate
basedir = os.path.abspath(os.path.dirname(__file__)) #Full directory path of the file I'm working with..here, sql1.py
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///' + os.path.join(basedir, 'data.sqlite')
app.config['SQLALCHEMY_TRACK_MODIFICATIONS'] = False
db = SQLAlchemy(app)
Migrate(app,db) #Here it connect the application "app.py"
# with the database "db"
class puppy(db.Model):
__tablename__ = 'Name Provided by me!!'
id = db.Column(db.Integer,primary_key = True)
name = db.Column(db.Text)
age = db.Column(db.Integer)
def __init__(self,name,age):
self.name = name
self.age = age
def __repr__(self):
return f"puppy {self.name} is {self.age} year/s old!"
I looked into every solution I found (here and this)and made sure everything was correct! I ran this command when my environment was activated which had installed every package needed including SQLAlchemy and Flask-Migrate.
I even deleted them (packages) and re-installed their latest versions but still getting the same error!
I'm using Python 3.8.5
You have some dependencies that are too old and incompatible with Python 3.8. At the very least, you should update the mako package:
pip install --upgrade mako
I had a similar issue I had to update flask_sqlalchemy even after doing this I had issues. I ended up having to make a new virtual environment, I would make a small hello world project on another virtual environment to see if that works.
For me, it was giving the same error, so I removed __init__.py file from the folder which has app.py
After removing I ran the
flask init db
it worked :)
So I have an extended User model (extended AbstractUser) called Profile. This was in a seperate app called "profiles". I was plugging in the standard login and realised it was looking for a "profile" app name as standard, so I renamed it (directories, code, DB schema) which I thought should work. app_name was actually already set to "profile" in apps.py, so didn't need to rename url references.
No dice. I get the error in the title.
So I removed all migrations (I'm at the stage where I can still do this OK :) ) and deleted the sqlite DB that I'm currently working with, thinking I'd just rerun the migrations and recreate everything.
Same error.

What have I missed as part of this rename?
Any other info I've missed posting that would help? (I've searched for any instance of "profiles", but everything is correctly renamed now, and the app was working OK prior to this, so it's purely this rename that's messed it up).
Edit: Can it be that "profile" conflicts with some internal python routine? That cProfile.py file under the python installation is defined as
#! /usr/bin/env python3
"""Python interface for the 'lsprof' profiler.
Compatible with the 'profile' module.
"""
Now that can't be anything to do with my project? Do I just need to call my app/extended user model something other than "profile"?
OK. So yes, it's a naming clash. I've renamed my "Profile" model and "profile" app as "UserProfile" and "user_profile" and updated everything accordingly. It all seems to work now ...
Just putting an answer here in case anybody comes along in the future with the same issue!
In my case, it was profile.py file.
Delete the file and try again.
In my case was the conflict between app - 'profile' and 'django-debug-toolbar':
I rename my app from 'profile' to 'account' and it solved the problem
I tried to use django_enums and got an error with list(cls) when making migrations:

I installed django-enums, enum and six:

(venv:SFS)rita#rita-notebook:~/Serpentarium/ServiceForServices/project/serviceforservices$ pip install enum
(venv:SFS)rita#rita-notebook:~/Serpentarium/ServiceForServices/project/serviceforservices$ pip install six
Using in Models.py:
...
from django_enums import enum
...
class StatusEnum(enum.Enum):
__order__ = 'AT BT BC AC' # for python 2
AT = (u'АВ', u'Активен временно')
BT = (u'БВ', u'Блокирован временно')
BC = (u'БП', u'Блокирован постоянно')
AC = (u'АП', u'Активен постоянно')
class EmployeesStatus(models.Model):
name = models.CharField(max_length=128)
status = enum.EnumField(StatusEnum, default=StatusEnum.AT)
It seems like project is alive, it also was updated for Django 1.10 and compartible with python 2 allegedly. So, what I'm doing wrong?
It looks like you are trying to use the backported enum from the 3.4 stdlib, but you installed enum -- you need to install enum34.
Trying to use django-shopify-sync in a Django 1.9 project. When loading the config for the app it gives me the following error, likely because it's trying to load some models in the config?
Tried moving the the two imports that eventually import models into the ready() function below, but still getting the same error. Culpirt lines 2 and 3 in the following file https://github.com/andresdouglas/django-shopify-sync/blob/master/shopify_sync/apps.py

It looks like you may have an ordering issue. Make sure your application is in the INSTALLED_APPS tuple after django-shopify-sync. You can find a few more details in the Application registry documentation.
As unsatisfying as an inline import is, you may be stuck with it. I'd suggest moving
from shopify_sync.handlers import webhook_received_handler
from shopify_webhook.signals import webhook_received
into the ready method in apps.py. This will delay the import until the models are ready.
The change I tried is:
diff --git a/shopify_sync/apps.py b/shopify_sync/apps.py
index 663b43b..0bc1fcc 100644
