如何使用表单django从模型中获取项目并将同一项目保存到另一个模型中

# models.py
from django.db import models

class Project(models.Model):
    name = models.CharField(max_length=100)
    # 其他字段...

class SavedProject(models.Model):
    project = models.ForeignKey(Project, on_delete=models.CASCADE)
    # 其他字段...

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

class ProjectForm(forms.Form):
    project = forms.ModelChoiceField(queryset=Project.objects.all())

# views.py
from django.shortcuts import render
from .forms import ProjectForm
from .models import SavedProject

def save_project(request):
    if request.method == 'POST':
        form = ProjectForm(request.POST)
        if form.is_valid():
            project = form.cleaned_data['project']
            saved_project = SavedProject(project=project)
            saved_project.save()
            # 其他处理...
    else:
        form = ProjectForm()
    
    return render(request, 'save_project.html', {'form': form})

# save_project.html
<form method="post">
  {% csrf_token %}
  {{ form.as_p }}
  <button type="submit">保存项目</button>
</form>
