在表单中选择多个选项，并使用django将所有选择的值存储在模型中

from django.db import models

class Option(models.Model):
    name = models.CharField(max_length=100)

    def __str__(self):
        return self.name

from django.db import models

class MyModel(models.Model):
    options = models.ManyToManyField(Option)

    def __str__(self):
        return f"MyModel {self.pk}"

from django import forms
from .models import Option

class MyForm(forms.Form):
    options = forms.ModelMultipleChoiceField(queryset=Option.objects.all())

from django.shortcuts import render, redirect
from .forms import MyForm
from .models import MyModel

def my_view(request):
    if request.method == 'POST':
        form = MyForm(request.POST)
        if form.is_valid():
            options = form.cleaned_data['options']
            my_model = MyModel.objects.create()
            my_model.options.set(options)
            return redirect('success')
    else:
        form = MyForm()
    return render(request, 'my_template.html', {'form': form})

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