我无法从后端 Django 检索 OneToOneField 数据

Question

我可以从用户后端获取数据，例如 user.id 但是当我想从 OneToOneField 获取数据时，例如 user.checkAdmin.isAdmin 它没有在 html 页面中显示任何数据

views.py

def registerView(request):
    if request.method == "POST":
        form = UserCreationForm(request.POST)
        isAdminForm = checkAdminForm(request.POST) #
        if form.is_valid() and isAdminForm.is_valid():
            user = form.save()
            isAdminFormObject = isAdminForm.save(commit=False)
            isAdminFormObject.user = user
            isAdminFormObject.save()
            return redirect('login_url')
    else:
        form = UserCreationForm()
        isAdminForm = checkAdminForm()

    return render(request, 'registration/register.html',{'form':form,'isAdminForm':isAdminForm})

Forms.py

from django import forms
from .models import checkAdmin


class checkAdminForm(forms.ModelForm):
    class Meta:
        model =  checkAdmin
        fields = ['isAdmin']

models.py

from django.db import models
from django.contrib.auth.models import User

# Create your models here.

class checkAdmin(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    isAdmin = models.BooleanField(default=False)

    def __str__(self):
        return self.user.username

dashboard.html

{% extends 'index.html' %}
{% block content %}
   <h1>Welcome, {{ user.id }}</h1>
   <h1>check?,{{ user.checkAdmin.isAdmin }}</h1>


    <button>Mark Attendance</button>  <button>Mark Leave</button>  <button>View Attance</button>
<a href="{% url 'logout' %}">Logout</a>
{% endblock %}

Answer 1

使用 checkadmin 而不是 checkAdmin

{% extends 'base.html' %}
{% block content %}
   <h1>Welcome, {{ user.id }}</h1>
   <h1>check?,{{ user.checkadmin.isAdmin }}</h1>
   <button>Mark Attendance</button>  <button>Mark Leave</button>  <button>View Attance</button>
    <a href="">Logout</a>
{% endblock %}
