I've ported my GAE project to django-nonrel, and now I would like to have link from my object to Django User object:
class Opinion(google.appengine.ext.db.Model):
...
author = db.ReferenceProperty(django.contrib.auth.User)
Unfortunately, that's not possible, since you only can link GAE models this way.
Question - what's the best way to solve this? Is it possible or should I work it around somehow?
I don't want to migrate my old GAE model since I already have a bunch of data there.
My initial googling and searching brought me nothing good:
On django-nonrel list I read:
You cannot use appengine model into django-nonrel. You need alter all
your models to django proper. That is, use original
django-registration app not the appengine-patch provided registration.
Another question, exactly like mine, was left unanswered.
... and I've found another place where people recommend switching to Django models.
I guess that's that then, there is no way of doing what I need, one needs to migrate.

I am reading Django documentation (https://docs.djangoproject.com/en/3.0/ref/contrib/contenttypes/#module-django.contrib.contenttypes).
I did not understand content type app, the Django docs describe it as below
Django includes a contenttypes application that can track all of the models installed in your Django-powered project, providing a high-level, generic interface for working with your models.
Can someone explain this from beginner perspective ?
I have experience in developing websites in Django but never touched in this app.
Example: you want to make user-related logging, something like an audit module in user profile. You have dozen of models that could be logged. User, Order, Task, Product, etc.
So your main model will be something like AuditEntity.
How to make it general for all possible current (and future models) that could be logged here? Which type of field do you need?
The answer is Django contenttypes.
If you want - try to implement such a model's structure to understand how it works.
I think that what is trying to tell you is that you can have different content (in blocks, as it is organized in "blocks" and it is very "module friendly", I hope to give the idea), this content is made up of different things, especially models, let's just say that they are like big classes of things needed in your application (don't judge this expression, I know it is not professional but is the more beginner friendly I can write now), hope this makes more clear!
I need to integrate Django-CMS 3.x into an existing project (mypjc hereafter). I already checked this question (and other similar) but they point to a tutorial page that is no longer available.
I'm a bit confused by the tons of infos you can find online and I have not really understood if Django-CMS can be integrated as an app into an existing and independently running Django project.
mypjc (using Django 1.8) would benefit from a user friendly CMS. Basically I'd the user to be able to write texts and to load in their posts images stored in the (common) database, images that are created by the user in mypjc.
Is it possible? if yes, could anyone help me defying the steps needed to make the integration clean and successful?
Thank you in advance for any help you could provide.
With Django CMS, it is indeed possible to integrate it into an existing project.
If you already have an existing project with URL/menu management, then you can simply integrate just the per-page CMS, which can be added as additional field to your model:
from django.db import models
from cms.models.fields import PlaceholderField
class MyModel(models.Model):
# your fields
my_placeholder = PlaceholderField('placeholder_name')
# your methods
You can find more information here.
For any existing projects, you are likely to need to use the manual installation process outlined here.
So I have a website that was using the built in django user model with some extensions. For various reasons, I wanted to instead use a custom user model. I have it built and runs beautifully on my local machine.
Now, I have integrated it into the development version of my website, but I am having some problems. When I try to add a new field, the migrations won't work, because it tries to create a brand new initial table with the same names, which won't work. Using South for my migrations.
To combat that, I tried to rename all the tables, and then run the migrations, but that won't work because of foreign key issues. I tried to work around that, but ran into more problems when I tried to rename foreign keys.
If you would like more insight into the problem, please ask.
I feel as though there has gotta be an easier way to go about this. I would love any insight. Thanks!
I'm building my first python app on app-engine and wondering if I should use Django or not.
What are the strong points of each? If you have references that support your answer, please post them. Maybe we can make a wiki out of this question.
Aral Balkan wrote a really nice piece addressing this very question. Its a year or so old, so take it with a grain of salt - I think that a lot more emphasis should be put on the awesomeness of django's Object-Relational-Model. Basically, IMHO, it all comes down to whether or not you have a preference for using DJango's object model (which I happen to).
If it's not a small project, I try to use Django. You can use the App Engine Patch (http://code.google.com/p/app-engine-patch/). However, the ORM cannot use Django's meaning your models.py will still be using GAE's Datastore.
One of the advantages of using Django on GAE is session management. GAE does not have a built-in session.
You won't be able to using most Django 3rd-party apps though especially those with model changes. I had to build my own tagging app for GAE.
Does anyone know of a django forum plugin that allows each member to have his own forum? If there isn't anything, than what would be the best way to accomplish this with a "regular" forum plugin for Django?
I once created a feature matrix of all Django forum apps I could find. It might be a bit outdated now, though (contributions welcome).
At least django-threadedcomments uses generic foreign keys, so you can attach a message thread to any database object, including users.
Look at DjangoBB.
Yep, the forum app of SCT can be used for this - simply set it up and create multiple "community Groups" (these are similar to vhosts) and map them to subdomains - each community group would have separate forum categories, can have separate templates, separate user permissions, etc. (but they will obviously share the same django users and their profiles) - as an example.. the following websites are all hosted on the same instance:
SCT website
My personal website/blog (the blog is also based on SCTs forum)
ShelfShare Community
Check out diamanda. I'm not sure it does what you need as far as the each user having its forums, but that's probably not too hard to hack on top. Probably as simple as adding a few ForeignKeys into auth.User to the diamanda models. In general django pluggables and djangoapps are good places to look for django stuff that is already written. Also, check out pinax.
I believe the Sphene Community Tools can do this.
