Wagtail Page.objects.descendant_of(inclusive=False) Error
I'm using Django 2.0 with the latest version of Wagtail CMS. I am pretty new to Wagtail and I am trying to query the children of EventIndexPage which is EventPage and have them appear on my HomePage. I am trying to use this line of python in home app models.py below: special_events = EventIndexPage.objects.descendant_of(inclusive=False) But It returns: return getattr(self.get_queryset(), name)(*args, **kwargs) TypeError: descendant_of() missing 1 required positional argument: 'other' When I try putting "EventPage" in before "inclusive=false" I get a type error because its an array not an integer. docs: http://docs.wagtail.io/en/v2.0/reference/pages/queryset_reference.html Models.py of the home app: from django.db import models from event.models import EventIndexPage from wagtail.core.models import Page from wagtail.core.fields import RichTextField from wagtail.admin.edit_handlers import FieldPanel class HomePage(Page): body = RichTextField(blank=True) special_events = EventIndexPage.objects.descendant_of(inclusive=False) content_panels = Page.content_panels + [ FieldPanel('body', classname="full"), ] Models.py of event app from django.db import models from wagtail.core.models import Page from wagtail.core.fields import RichTextField from wagtail.admin.edit_handlers import FieldPanel from wagtail.search import index class EventIndexPage(Page): intro = RichTextField(blank=True) content_panels = Page.content_panels + [ FieldPanel('intro', classname="full") ] class EventPage(Page): date = models.DateField("Post date") intro = models.CharField(max_length=250) body = RichTextField(blank=True) search_fields = Page.search_fields + [ index.SearchField('intro'), index.SearchField('body'), ] content_panels = Page.content_panels + [ FieldPanel('date'), FieldPanel('intro'), FieldPanel('body', classname="full"), ] -
Get site-specific user profile fields from user-created object
I am using Django sites framework (Django 2.1) to split an app into multiple sites. All of my models except the User model are site-specific. Here is my Post model: post.py class Post(models.Model): parent = models.ForeignKey( 'self', on_delete=models.CASCADE, related_name='children', related_query_name='child', blank=True, null=True, ) title = models.CharField( max_length=255, blank=True, ) body_raw = models.TextField() body_html = models.TextField(blank=True) user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, ) site = models.ForeignKey(Site, on_delete=models.CASCADE) on_site = CurrentSiteManager() I have no problem separating posts out by site. When I want to get the posts, I call: posts = Post.on_site.filter(...) I have a separate model called UserProfile. It is a many-to-one profile where there is a unique profile created for each user-site combination (similar to profile implementation at SE). The profile has a reputation attribute that I want to access when I get any post. user_profile.py class UserProfile(models.Model): user = models.ForeignKey(get_user_model(), on_delete=models.CASCADE) reputation = models.PositiveIntegerField(default=1) site = models.ForeignKey(Site, on_delete=models.CASCADE) on_site = CurrentSiteManager() How do I access the user's username (on the User model) as well as the user's reputation (on the UserProfile model) when I get Posts from a query? -
Django, object-level permissions and calculated fields
I've been scouring the internet for answers, but my Google-fu isn't quite working. I need to have object-level permissions and calculated fields based on the fields a user has access to. I must use Django. I am allowed to import addons. For example, consider the following use case: A business would like to provide an inventory tracking system for sales clerks and managers. The system tracks how much inventory each sales clerk starts the month with, how much they have sold that month, and how much inventory they have remaining (calculated field :(start_inventory - sold_inventory = currentInventory)). A sales clerk can only see the start, sold and current inventory for themselves. A manager can see all the start, sold and current inventory for the sales clerks that they manage. Now, start and sold inventory are recorded in the model - and it seems quite simple to use something like django-guardian's get_objects_for_user() just for the start and sold inventory... but for current inventory? My first thought was to define a function or a manager with a function in the model.py that returns the model + the calculated current inventory field. However, because that method is in the model.py... I can't use … -
Django Admin Static Files No Longer Working: "Did you forget to register or load this tag?"
I am able to create a Django Project and and my admin site works fine initially. After I create an app, register it, setup static files, the Django Admin page actually starts complaining that I failed to give it static files at all. (Something I don't consider myself to be on the hook for) So when I hit: http://127.0.0.1/admin (like I always do), somewhere in the timeline, I face an error that says: TemplateSyntaxError at /admin/login/ Invalid block tag on line 4: 'static', expected 'endblock'. Did you forget to register or load this tag? Okay so that seems like a silly question, but why am I being asked if I registered the static tag? What about my static tag destroyed theirs? I'm not even sure which files I should be looking at right now. In settings.py: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'myapp', ] DEBUG = True ... snip - irrelevant stuff # Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/2.1/howto/static-files/ STATIC_URL = '/static/' STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'comics', 'static'), ] The file that is breaking down isn't mine to edit. It's the admin one. Where should I be looking? I should also note that my own app … -
Best way to implement models with many overlapping fields in Django?
I need to implement the following logic: there is a big model Base with many fields and several smaller models sharing some field subsets with it and with each other. For example, let's say that Base has fields a, b, c, d, e and f; model A has fields a, b, g; model B has fields b, c, d, g; model C has fields d, e, f, g. Trying to do proper inheritance from abstract models will very quickly lead to a mess, but making manual copies of fields also seems suboptimal, since every field from the main model is present in the smaller ones and so will have to be listed twice. What's a good way to approach this? -

NOT NULL constraint failed error in django despite having null set to true and blank set to true

How do I seralize related objects in Django to use for fixtures?
How do I seralize related objects in Django to use for fixtures? class Selector(models.Model): id = models.AutoField(primary_key=True) site = models.ForeignKey(AlexaSite, on_delete=models.PROTECT, related_name='selectors') If I do something like this: selector = Selector.objects.filter(id=selector_id).all() data = serializers.serialize("json", selector) I only get the selector object, but not the related site. This becomes an issues when actually trying to use the fixture because I get a foreign key error saying “Site of id 5 does not exist”. Now I also tried serializing the selector by doing: selector = SelectorsSerializer(selector) But this gives me a Serializer object, not a string, which I can’t make a fixture out of. So I either need to be able to: a) make fixtures from related objects using serializers.serialize(“json”, selector) b) convert my Serializer object to a json string that can actually be used for a fixture. Any ideas? (edited) -

delete object in template - django
My main page has many sub pages and on each of the sub pages i have many items listed. Next to item i want a delete button and when you press it the item must be deleted but you must remain on the same page.

Django inline formsets updating a model
