如何在同一个 Django 模板中使用更多不同的表单？

Question

在我的项目中，我有一个模板，我试图为不同的用例放置两种表单。我以前从来没有遇到过这个问题，所以我真的不知道从哪里开始在同一个页面中使用两个表单。

起初我想创建另一个视图来处理每个表单，但我认为这个解决方案会给我的模板的渲染带来问题，除了如果我再次使用另一个模板遇到这个问题时不可持续。

经过一些研究，我找到了一个解决方案，但它适用于基于类的视图，但我想避免这种情况，因为我的视图已经是基于函数的视图，我必须在我的代码。

是否可以使用基于函数的视图来解决这个问题？每一个建议都值得赞赏

第一个字段

class FirstForm(forms.ModelForm):

    firstfield = forms.CharField() 
    secondfield = forms.CharField()
    class Meta:
        model = MyModel
        fields = ("firstfield", "secondfield")
    def save(self, commit=True):
        send = super(FirstForm, self).save(commit=False)
        if commit:
            send.save()
        return send**

第二种形式

class SecondForm(forms.ModelForm):

    firstfield = forms.FloatField() 
    secondfield = forms.Floatfield()
    thirdfield = forms.CharField()

    class Meta:
        model = MyModelTwo
        fields = ("firstfield", "secondfield", "thirdfield")

    def save(self, commit=True):
        send = super(SecondForm, self).save(commit=False)
        if commit:
            send.save()
        return send

模板

  <h3> First Form </h3>
  <form method="post" novalidate>
      {% csrf_token %}
      {% include 'main/includes/bs4_form.html' with form=form %}
      <button type="submit" class="btn btn-danger" style="background-color: red;">SUBMIT</button>
  </form>

  <h3> Second Form </h3>
  <form method="post" novalidate>
      {% csrf_token %}
      {% include 'main/includes/bs4_form.html' with form=form %}
      <button type="submit" class="btn btn-danger" style="background-color: red;">SUBMIT</button>
  </form>

编辑：我的观点：

def myview(request):

    # if this is a POST request we need to process the form data
    if request.method == 'POST':
        # create a form instance and populate it with data from the request:
        form = FirstForm(request.POST)
        # check whether it's valid:
        if form.is_valid():
            # process the data in form.cleaned_data as required
            # ...
            # redirect to a new URL:
            send = form.save()
            send.save()
            messages.success(request, f"Success")

    # if a GET (or any other method) we'll create a blank form
    else:
        form = FirstForm()

    return render(request,
                  "main/mytemplate.html",
                  context={"form":form})

这个答案有点笼统，因为您没有包含视图功能。您可以将这些表单中的每一个添加到视图的上下文中。像这样的：

views.py

...
from .forms import FirstForm, SecondForm
...

def some_view(request):

    context = {
        'first_form': FirstForm(request.POST or None),
        'second_form': SecondForm(request.POST or None)
    }
    return render(request, "app/some_template.html", context)
