如何在基本html模板django中创建简单表单 [英] How to create a simple form in the base html template django

问题描述

我有一个包含多个页面的Django应用.像菜单或页脚一样，在所有这些页面中都重复了一些元素，因此我创建了基本模板并添加了这些重复的代码.现在，我想在基础模板的页脚上方有一个表单.但是我不知道如何使它工作.我应该创建一个返回base.html的视图吗?如何在网站的每个页面上继承此表单?请指导我；我有点泡菜！

I have a Django app that contains multiple pages. Like the menu or footer, some elements are repeated in all of these pages, so I created a base template and added these duplicated codes. Now I want to have a form above the footer in the base template. But I don't know how to make it work. Should I make a view that returns the base.html? How can I inherit this form on every page of the website? Please guide me; I'm in a bit of a pickle!

这是我的context_processor:

this is my context_processor :

def base_forms(request):
    return {       
        'info_form': BasedContactForm()
    }

这是我的base.html:我将其扩展到所有其他页面:

and this is my base.html: I extend it in all other pages:

<form method="post" action="">
      {% csrf_token %}
      {{ info_form }}
   </form>

这是我的Blog应用视图:

and this is my Blog app views:

def base_info_form(request):
 if request.method == 'POST':
    info_form = BaseContactForm(request.POST)
    if info_form.is_valid():
        info_form.save()
        return redirect('Home-Page')
    else:
        info_form = BaseContactForm()
    return render(request, '', {'info_form': info_form})

推荐答案

您可以通过设置 TEMPLATES>将一些数据添加到全局上下文中.选项>context_processors -写作您自己的上下文处理器.

对于扩展模板，请使用模板标签 扩展 (Django文档).

And for extending templates use template tag extends(Django Docs).

1.将变量添加到上下文中

创建 yourapp/context_processors.py :

from django.conf import settings

from yourapp.forms import MyForm


def base_data(request):
    data = {}
    # MyForm(request.GET, user=request.user)
    data["my_form"] = MyForm()
    data["my_email"] = settings.MYEMAIL
    return data

并将其添加到 settings.py 中的 context_processors :

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [
           ...
        ],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                ...
                'yourapp.context_processors.base_data',
            ],
        },
    },
]

现在您可以在任何模板中访问此数据:

Now you can access your this data in any template:

{{ my_form }}, {{ my_email }}

2.扩展模板

您还可以使用模板标签 扩展 ( Django文档)来扩展模板:

You can also use template tag extends(Django Docs) to extend your templates:

template.html
base.html

在template.html中，以下路径将是有效的:

In template.html, the following paths would be valid:

{% extends "base.html" %}
<div class="container">
    Some HTML code
</div>

其他信息 TEMPLATES ( Django文档)和 OPTIONS > ( Django文档)的可用参数.

Additional info TEMPLATES(Django Docs) and OPTIONS (Django Docs) available parameters.

更新

views.py :

def contact(request):
    if request.method == 'POST':
        form = BaseContactForm(request.POST)
        if form.is_valid():
            form.save()
            return redirect('Home-Page')
    else:
        form = BaseContactForm()
    return redirect(request.META.get('HTTP_REFERER'))

urls.py :

path('contact/', views.contact, name='contact'),
