Switching database backend in Mezzanine
I am trying to script a series of examples where the reader incrementally builds a web application. The first stage takes place with Mezzanine's default configuration, using built-in SQLlite: sudo pip install mezzanine sudo -u mezzanine python manage.py createdb After the initial examples are complete, I want to switch the existing setup to a mysql backend. If that is too complex, I at least want to re-create the built-in examples that come with Mezzanine on the new backend, but Mezzanine won't allow re-running createdb CommandError: Database already created, you probably want the migrate command This seems like something that should be incredibly simple, yet I can't seem to get it quite right (and migrate alone did not do the trick). Google and official docs not helping either. -

I just have started learning django in its 1.10 version. In a project (called refugio) I have created an app called mascota. This is my views.py file for my app: from __future__ import unicode_literals, absolute_import from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("Index") Also, I already have written my urls.py file for it: from django.conf.urls import url from apps.mascota.views import index urlpatterns = [ url(r'^$/', index), ] And I have modified the url.py file of my project: from django.conf.urls import url, include from django.contrib import admin urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^', include('apps.mascota.urls')), ] But when I run the server of my project, it sends me the next error message: I know this is a dummy question, but I don't know what is wrong, I have already checked my urls sentences, but I see everything ok. I will appreciate your help. Ps.: My app is located inside a folder called apps. Regards. -

Django FileNotFoundError in a view when returning HTML using codecs
I am creating a view in Django that returns a static HTML page, and my code for that view is as follows: from django.shortcuts import render from django.http import HttpResponse from django.shortcuts import render_to_response import codecs # Basic HTTP response that returns my html index # To call this view, map it to a URLconf def index(request): # When a request is called, return my index.html html = codecs.open("index.html", "r") return HttpResponse(html.read()) When I fire up the Django dev. server and navigate to my app, instead of the rendering of index.html that I expect, I am confronted with a FileNotFoundError at /myapp/ as well as [Errno 2] No such file or directory: 'index.html'. I know for a fact that index.html is a real file in the same directory as myviews.py, and I have also tried debugging by opening a debug.txt in the same directory and returning that, but with the same result. When I open the python shell in the same directory and try to open the same file, it works without a hitch. Any insight would be appreciated, as I am thouroughly stumped. -

How do I remove the circular dependency in my Organization-Owner-Member models?
Heyo, I'm fairly new to this stuff so please pardon me if this is a stupid question. I'm trying to create an app where users can create organizations and join already existing ones. My requirements are: an organization may have only one user designated the owner (the user who creates it) users must be able to join several organizations users must be able to create organizations and therefore be owners of multiple organizations So far I've got the following models.py: from django.db import models from django.utils.translation import ugettext_lazy as _ from myapp.users.models import User class TimeStampedModel(models.Model): created = models.DateTimeField(auto_now_add=True) updated = models.DateTimeField(auto_now=True) class Meta: abstract = True class Org(TimeStampedModel): name = models.CharField( _('Organization name'), max_length=255, ) owner = models.OneToOneField('OrgOwner') members = models.ManyToManyField( 'OrgMember', related_name='organization_members' ) users = models.ManyToManyField( User, related_name='organization_users' ) def __str__(self): return self.name class OrgMember(TimeStampedModel): user = models.ForeignKey( User, related_name='user_profile' ) organization = models.ForeignKey( Org, related_name='member_organization' ) def __str__(self): return self.user.username class OrgOwner(TimeStampedModel): member = models.OneToOneField(OrgMember) organization = models.OneToOneField(Org) def __str__(self): return self.member.__str__() My issue is that the way I've designed the models so far, I have a circular dependency.

Django {% block %} explanation
I'm a Django beginner and I wanted to try and learn some of the Django-CMS basics. When I started editing the default template that was generated by the installer, I noticed there are {% block ... %} blocks, but I couldn't find any documentation on what block means or more specific what block title and block content mean. Both the Django and the Django-CMS documentation lacks of such an explanation, which is weird given the fact that this seems pretty basic. When I removed the block title block, the title got messed up. I'm using: Django 1.8.15 django-cms 3.4.1. -
