我創建了一個 django ModelForm，它沒有出現在我的 html 模板中，我想確定為什么該代碼沒有呈現我的表單？

Question

模型.py

from django.db import models


# Create your models here.
class Subscriber(models.Model):
    """A subscriber Model"""
    email = models.CharField(max_length=255, blank=False, null=False, help_text="Subscriber Email Address", unique=True)
    full_name = models.CharField(max_length=100, blank=False, null=False, help_text="First and Last Name")

    class Meta:
        verbose_name = "Subscriber"
        verbose_name_plural = "Subscribers"

forms.py

from django.forms import ModelForm
from .models import Subscriber


class SubscriberForm(ModelForm):
    class Meta:
        model = Subscriber
        fields = ["email", "full_name"]

視圖.py

from django.shortcuts import render
from .forms import SubscriberForm
from django.http import HttpResponseRedirect
from django.contrib import messages


# Create your views here.

def subscriber(request):
    if request.method == "POST":
        subscriber_form = SubscriberForm(request.POST or None)
        if subscriber_form.is_valid():
            subscriber_form.save()
            messages.success(request, "")
            return HttpResponseRedirect("/")
    else:
        subscriber_form = SubscriberForm()
    context = {
        "form_subscriber": subscriber_form
    }
    return render(request, "subscriber/subscriber_form.html", context)

subscriber_form.html

{% block content %}
    <div>
        <form method="POST">
            {% csrf_token %}
            {{ subscriber_form.as_ul }}
            <input type="submit" value="Submit">
        </form>
    </div>
{% endblock %}

只有我的提交按鈕正在發布，但該表格從未出現在我面前。 我完全遵循了 django 文檔，但仍然沒有得到任何好的結果。

Answer 1

它應該是form_subscriber而不是subscriber_form所以：

{% block content %}
    <div>
        <form method="POST">
            {% csrf_token %}
            {{ form_subscriber.as_ul }}
            <input type="submit" value="Submit">
        </form>
    </div>
{% endblock %}

此外，我建議您僅在視圖中使用SubscriberForm(request.POST)而不要將None用於GET請求，因為它已經在else條件下處理，因此：

意見.py：

def subscriber(request):
    if request.method == "POST":
        subscriber_form = SubscriberForm(request.POST)
        ...
