如何将外键合并到django表单中？

from django import forms
from .models import YourModel

class YourModelForm(forms.ModelForm):
    class Meta:
        model = YourModel
        fields = ['field1', 'field2', 'foreign_key_field']

from django.shortcuts import render
from .forms import YourModelForm

def your_view(request):
    if request.method == 'POST':
        form = YourModelForm(request.POST)
        if form.is_valid():
            form.save()
            # 处理表单提交成功的逻辑
    else:
        form = YourModelForm()
    
    return render(request, 'your_template.html', {'form': form})

<form method="post" action="{% url 'your_view' %}">
  {% csrf_token %}
  {{ form.as_p }}
  <input type="submit" value="Submit">
</form>
