django settings after mongodb setup
I had a project which I was working on happily, then I wanted to switch from sqlite to mongodb just to try things. Well, I only followed these instructions https://django-mongodb-engine.readthedocs.io/en/latest/topics/setup.html, but now my whole Django doesn't work. I can't do anything, no "python manage.py check", nor python manage.py runserver, not even django-admin stratproject to make a new one. I also rolled back to previous my commit, before I started to modify things, however, it seems that environmental variables are screwed, so it doesn't work either. I keep getting ImportError: No module named myapp.settings. I went into manage.py and modified it to settings which worked, but the problem went down, so it keeps telling me now that django.db.models.fields import (DateTimeField, DateField, ImportError: cannot import name BinaryField django.apps import AppConfig ImportError: cannot import name apps etc... I also tried to export DJANGO_SETTINGS_MODULE=myapp.settings as it's described here https://docs.djangoproject.com/en/1.10/topics/settings/, but this didn't change anything. Any try to call python manage.py check, which worked perfectly before, results in Unknown command: 'check' My question is: wtf? Do I just remove Django and install again? -

Python - Django - Model BooleanField Dependent On Other BooleanField In Same Model
I am using Django to write a web application and would like to know if it is possible to have a BooleanField within a model for which the value will be based on other BooleanFields in the same model. Basically, I would like one BooleanField in the model to be True only if all other BooleanFields in the model are True. For example, with the Model below: class ModelEx(models.Model): booleanA = models.BooleanField(default=False) booleanB = models.BooleanField(default=False) booleanC = models.BooleanField(default=False) booleanD = models.BooleanField(default=False) I would like booleanA to be True only if booleanB and booleanC and booleanD are True. I have not found any information about this so it would be great if anyone knew if there is a solution for this. Thanks. -

mezzanine showing pages only when loged in
I've got some trouble with my brand new mezzanine installation. After setting up mysql with UTF8 charset, migrating the model to the database and setting up a superuser for mezzanine I created a new page with some content that I wanted to show to my students. You can visit it here: fadenstrahl.de The page "Elektromagnetismus" is missing! It shows up as long as I am logged in but it hides when i'm logged out. And the checkbox "login required" is not checked! I was trying to set up this page as / (in the meta description) and redirect the homepage to this page in the ursl.py by commenting this line: # url("^$", direct_to_template, {"template": "index.html"}, name="home"), and uncommenting this line: url("^$", mezzanine.pages.views.page, {"slug": "/"}, name="home"), I had to add this at the beginning: import mezzanine.pages.views I got the same problem. But because due to the problem, I get a 404 because there is no homepage anymore. Why do I have to be logged in to see the content. I want it to be public. Thanks for your help and best regards, Pascal -

Django REST framework. Get object by unique url
I making rest api of my django project for mobile client. I have this model and API structure for Categories objects: models.py class Category(models.Model): title = models.CharField(max_length=200, verbose_name="Title") url = models.CharField(max_length=200, verbose_name="Url") api/serializers.py class CategoryDetailSerializer(ModelSerializer): class Meta: model = Category fields = [ 'id', 'title', 'url' ] api/views.py class CategoryViewSet(viewsets.ModelViewSet): queryset = Category.objects.all() serializer_class = CategoryDetailSerializer and api/urls.py urlpatterns = [ url(r'^(?P<pk>\d+)/$', CategoryViewSet.as_view({'get': 'retrieve'}), name='detail'), ] To retrieve Category object I use GET request to my_server_url/api/categories/[pk]/ Question is how can get object with it's url field (which is unique). e.g. like this: my_server_url/api/categories/category_1/ Is it possible with rest-framework? Or maybe I should get map of [pk]:[url] objects first, then get pk by url from it and pass it to existing request method..? -
