在Django上从HTML表单中选择一个模型实例

# forms.py
from django import forms
from .models import YourModel

class YourForm(forms.Form):
    model_instance = forms.ModelChoiceField(queryset=YourModel.objects.all())

# views.py
from django.views.generic import FormView
from .forms import YourForm

class YourView(FormView):
    template_name = 'your_template.html'
    form_class = YourForm
    success_url = '/success/'

    def form_valid(self, form):
        selected_instance = form.cleaned_data['model_instance']
        # 处理选中的模型实例
        return super().form_valid(form)

# your_template.html
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">Submit</button>
</form>
