HTML 期中的 Django 渲染表单

Question

我正在尝试在 html 中呈现一个表单，并尝试了普通的 {{ form }}。但是，当我访问由 python manage.py runserver 设置的站点时。我在表格应该去的地方得到以下信息（屏幕截图上突出显示的部分）

webpage

这是相关表单的代码。

forms.py

from django import forms
from django.forms import ChoiceField, ModelForm, RadioSelect
from .models import command_node
from .models import beacon


class Command_Form(ModelForm):
    class Meta:
        model = command_node
        fields = (
            'host_id',
            'current_commands'
        )
        
        host_id = forms.ModelChoiceField(
            required=True,
            queryset=beacon.objects.all(),
            widget=forms.Select(
                attrs={
                    'class': 'form-control'
                },
            )
        )

        current_comamnds = forms.ChoiceField(
            required=True,

            choices=[
                ('Sleep', "Sleep"),
                ('Open SSH_Tunnel', 'Open SSH_Tunnel'),
                ('Close SSH_Tunnel', 'Close SSH_Tunnel'),
                ('Open TCP_Tunnel', 'Open TCP_Tunnel'),
                ('Close TCP_Tunnel', 'Close TCP_Tunnel'),
                ('Open Dynamic', 'Open Dynamic'),
                ('Close Dynamic', 'Close Dynamic'),
                ('Task', 'Task'),
            ])

这是有问题的 html。我删除了不相关的部分

home.html

</br>
</br>
    <form action="" method=POST>
        {% csrf_token %}
        {{ form }}
        <button type="Submit" class="btn btn-secondary btn-sm">Submit</button>
    </form>
</body>
</html>

最后，我将这些观点包括在内，因为我怀疑它可能与此有关，但我不确定。我试图做到这一点，以便在提交表单时重新加载页面。

Views.py

from django.shortcuts import render
from django.http import HttpResponse
from .models import beacon
from .models import command_node
from .forms import Command_Form
from django.http import HttpResponseRedirect

def home(request):
    form = Command_Form,
    if request.method == "POST":
            form = form(request.POST)
            if form.is_valid():
                form.save()
                return render(request, 'home.html', {"form": form})

    return render(request, 'home.html', {"form": form},)

Answer 1

尝试：

form = Command_Form()
if request.method == "POST":
    form = Command_Form(request.POST)

我相信您没有实例化模型，这就是问题所在。
