问题 My question holds for any wagtail panel that returns select options from a foreignkey or M2M relationship, like a PageChooserPanel or SnippetChooserPanel. How can I filter the list of options server-side, for the user to only see the information he has access to? I have a Plan model. When creating a new plan, I would like request.user to only see the list of companies he is affiliated to. from modelcluster.models import ClusterableModel from wagtailautocomplete.edit_handlers import

问题 In regards to the image below, when I click "add entry", the new entry row no longer has the datetimepicker widget. Which is odd because it has the right class. The +1 field represents the django form auto-added additional field. Which seems to work fine. It's only the fields that are added after the page has rendered which may be a key to the solution. I am using the flatpickr package as my datetimepicker widget. trade_form.html {% extends 'dashboard/base.html' %} {% load static %} {% block

问题 Let's say I have a Django form with ChoiceField: class MyForm(forms.Form): name = forms.CharField(label="Name", required=True) some_object = forms.ChoiceField(label="Object", choices=[(0, '-----')] + [(x.id, x.name) for x in Obj.objects.all()]) Choisefield is being initialized with list of objects headed by 'empty choice'. There is no object with pk=0. In that form I have a clean() method: def clean(self): if not Obj.objects.filter(self.cleaned.data['some_object'].exists(): self.errors.update

问题 Hi have this structure to handle users posts and comments my post model is from django.db import models from django.contrib.auth.models import User class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, default=0) profile = models.ForeignKey('users.Profiles', on_delete=models.CASCADE, null=True, default=1, blank=True) title = models.CharField(max_length=100, blank=True, null=True) desc = models.CharField(max_length=1000, blank=True, null=True) photo = models

问题 Given a ChoiceField in Django fruits = ChoiceField(label="Fruits", choices=(('A', 'Apple'), ('B', 'Banana'), ('C', 'Cherry') ) How do I display the form options in Django Templates in 1.9? For example, I tried the following but cannot display the form data: <table class="table table-bordered table-condensed"> <tr> <th> <label for="{{form.fruits.id_label}}"> {{form.fruits.label}} </label> </th> <td>{% for value, displayable in form.fruits.choices %} <option value="{{value}}">{{displayable}}<

问题 I'm working on a django app to document trades. All the trade documentation is done on one page with an inline formset that shows all the entries and exits for a trade. All work well up to the datetimeinput field. If I remove the 'type' the form works great but is very non-user friendly. Working entries with no 'type' Non-working entries with 'type': 'datetime-local' So I guess you could say there are several issues datetime-local creates, or maybe it's not datetime-local to blame. I've been
