I'm trying to use the dynamic upload path, for django FileFiled.
This is my model:
def use_assignment_path(instance, filename):
return 'assignment/%s/%s' % (instance.name, filename)
class Assignment(models.Model):
admin = models.ForeignKey(Admin)
name = models.CharField(max_length=50, unique=True)
lang = models.CharField(max_length=5, default='c', choices=(('c', 'c'), ('java', 'java')))
pointsRecommended = models.IntegerField()
file0 = models.FileField(upload_to=use_assignment_path)
file1 = models.FileField(upload_to=use_assignment_path, default='', blank=True)
When I try to migrate the models I get this errors:
Traceback (most recent call last):

If have no idea why it occurs, when I'm using a static upload path it works perfectly fine.
I have have read several posts with similar questions but nothing helped till know.
Tanke you!
It looks as if your app name models is clashing with django.db.models. Try renaming your app, delete the initial migration, then rerun makemigrations and migrate.
delete "/media/sf_Websites/HM/trunk/assignments/models/migrations/0001_initial.py" file and try again

When I was working on a Django project (blog), I had an error(s) while working on the site. Here are the errors I have appeared:
1: When I entered the python command manage.py makemigrations blog(via the console) in the directory C:\mysite\site\miniproject , then there is this:

Although I did everything according to the instructions on the website https://pocoz .gitbooks.io/django-v-primerah/content/sozdanie-i-primenenie-migracij.html.
I did everything according to plan, I did everything in order and there was such a mistake. And I do not know how to fix it
Updated all the necessary libraries, entered them in manage.ру (which is located in the directory C:\mysite\site\miniproject ) import django, it didn't help
You have declared a ForeignKey somewhere but not provided the on_delete keyword argument.
If you post the BlogPost model, I can give you an exact answer, but you probably want something like:
models.ForeignKey(..., on_delete=models.CASCADE)
To fix the issue add the key word argument to the BlogPost model in blog/models.py
If you debug your error its pretty self-explanatory:
In line 12 File "C:\mysite\site\miniproject\blog\models.py", line 12, in Post
in your Post model you have a field
author = models.ForeignKey(User, related_name='blog_posts')
You need to change that to:
author = models.ForeignKey(User, on_delete=models.CASCADE, related_name='blog_posts')
I created a web application using Djanjo framework, and then when I am trying to create a REST API, after configuring all the relevant files such as models.py, admin.py, serializers.py, views.py, and settings.py. It shows an error while importinng the model from rest_framework. The traceback is as follows:

if more code is require then tell me in a comment session. i will update my question with that information.
You should not run makemigrations on heroku. Migrations is something that should be added to your repo and then your deployment plan uses those migration files to execute migrations on the DB.
Heroku has a release phase when python manage.py migrate should be executed. If migrations fail, new code that uses them won't be deployed.
If you don't want to add this phase because you don't feel like it - no problem. Just don't run makemigrations.
If, for some reason, you won't be able to create migrations locally, comment out this form, run makemigrations, run migrate and uncomment this code.
If heroku still complains, repeat these steps ^ on heroku as well.
But the idea is that on heroku you run only
python manage.py migrate (release phase if possible)
gunicorn something something (web dyno)

I am getting an error when trying to syncdb through the command line.
My goal is a basic music search/delete/update/add application with certain criteria and I am using Python and Django.
The class I'm trying to write:
from django.db import models
# music search
class musicsearch(models.Model):
id = models.IntegerField
title = models.CharField(max_length=40)
artist = models.CharField(max_length=40)
genre = models.CharField(max_length=20)
The error traceback:

I can see two issues with your model.
You didn't create an instance of the IntegerField; you need to call it:
id = models.IntegerField()
# ^^
You are creating tuples for the other fields, because you end each field with a comma:
title = models.CharField(max_length=40),
# ^
Remove those commas.
You don't really have to specify your own id field; models are by default given an id field automatically. See Automatic primary fields in the Django models documentation:
By default, Django gives each model the following field:
id = models.AutoField(primary_key=True)
This is an auto-incrementing primary key.
Since your specified your own id field that doesn't use primary_key=True, your model is probably going to run into problems with that too.
Below line of code is missing
id = models.IntegerField(primary_key= True)
You are missing two () for your id integerfield.
id = models.IntegerField()
