python - 如何在同一 HTML 页面中显示来自 django 表单的用户提交的值

Question

我想在同一个 HTML 页面中显示用户提交的值。我能够显示这些值，但它采用 python 字典格式。我得到了结果：'first_name': 'Tom', 'last_name': 'Hanks'}，有没有办法分别只显示名字和姓氏。

这是views.py：

from django.shortcuts import render
from django import forms


class DbNames(forms.Form):
    first_name = forms.CharField(label="First Name")
    last_name = forms.CharField(label="Last Name")


def index(request):
    return render(request, "emp/index.html")


def form_gen(request):
    form = DbNames()
    if request.method == "POST":
        form = DbNames(request.POST)
        if form.is_valid():
            return render(request, "emp/users.html", {
                "form_data": form.cleaned_data
            })
        else:
            print('ERROR')
    return render(request, "emp/users.html", {
        "result": form
    })

def form_gen(request):
    form = DbNames()
    if request.method == "POST":
        
        form = DbNames(request.POST)
        if form.is_valid():
            # Because form.cleaned_data return a dict
            first_name = form.cleaned_data['first_name']
            last_name = form.cleaned_data['last_name']
            return render(request, "emp/users.html", {
                "first_name": first_name, "last_name": last_name,
            })
        else:
            print('ERROR')
    return render(request, "emp/users.html", {
        "result": form
    })

并在您的情况下访问您的模板中的这些值"emp/users.html"。您可以像这样使用 django-template-language 语法：

<p>{{ first_name }} </p>
<p>{{ last_name }}</p>
