在Django中传递和接收object pk来修复CreateView中的外键字段

from django.views.generic import CreateView
from .models import Order

class OrderCreateView(CreateView):
    model = Order
    fields = ['customer']

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        context['customer_pk'] = self.kwargs.get('pk') # 获取object pk的值
        return context

<!-- urls.py -->
from django.urls import path
from .views import OrderCreateView

app_name = 'orders'
urlpatterns = [
    path('create/<int:pk>/', OrderCreateView.as_view(), name='order_create'),
]

<!-- order_form.html -->
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <input type="hidden" name="customer" value="{{ customer_pk }}">
  <button type="submit">Submit</button>
</form>
