第3章 Django中的Template模板

3-9 项目练习-Django模板实践与枚举学习、消息屏蔽

1.进入项目 message_test 下目录 app，修改文件 views.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-

from django.views.generic import View
from django.http import HttpResponse

class LessionThree(View):
    def get(self, request, message_type):
        # message = request.GET.get('message', '这里没有内容')
        return HttpResponse(message_type)

2.进入项目 message_test 下目录 message_test，修改文件 urls.py　

#!/usr/bin/env python
# -*- coding:utf-8 -*-

from django.urls import path
from .views import LessionThree

urlpatterns = [
  path('three/<str:message_type>', LessionThree.as_view(), name='three')
]

3.进入项目 message_test 下目录 app，添加文件 consts.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from enum import Enum

class MessageType(Enum):
    info = 'info'
    warning = 'warning'
    error = 'error'
    danger = 'danger'

4.在命令窗口进行调试

python manage.py shell
from app.consts import MessageType
MessageType.info
MessageType.info.value

5.进入项目 message_test，添加目录 templates

6.进入项目 message_test 下目录 templates，添加文件 three.html

7.进入项目 message_test 下目录 message_test，修改文件 settings.py

#修改模板路径
TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR + '/templates'],
        'APP_DIRS': True,
        'OPTIONS': {
            'context_processors': [
                'django.template.context_processors.debug',
                'django.template.context_processors.request',

class LessionThree(View):

    TEMPLATE = 'three.html'

    def get(self, request, message_type):
        data = {}

        try:
            message_type_obj = MessageType[message_type]
        except Exception as e:
            data['error'] = '没有这个消息类型 {}'.format(e)
            return render(request, self.TEMPLATE, data)
        message = request.GET.get('message', '')

        if not message:
            data['error'] = '消息不可为空'
            return render(request, self.TEMPLATE, data)

        data['message'] = message
        data['message_type'] = message_type_obj

        return render(request, self.TEMPLATE, data)

9.进入项目 message_test 下目录 app，修改文件 consts.py

#!/usr/bin/env python
# -*- coding:utf-8 -*-
from enum import Enum

class MessageType(Enum):
    info = 'info'
    warning = 'warning'
    error = 'error'
    danger = 'danger'

MessageType.info.label = '信息'
MessageType.warning.label = '警告'
MessageType.error.label = '错误'
MessageType.danger.label = '危险'

MessageType.info.color = 'green'
MessageType.warning.color = 'orange'
MessageType.error.color = 'gray'
MessageType.danger.color = 'red'

10.进入项目 message_test 下目录 templates，修改文件 three.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>
{% if error %}

MessageType.danger.label = '危险'

MessageType.info.color = 'green'
MessageType.warning.color = 'orange'
MessageType.error.color = 'gray'
MessageType.danger.color = 'red'

SensitiveWord = ['天气', '坏人', '不开心']

14.在项目 message_test 下目录 app，新建目录 templatetags

15.在项目 message_test 下目录 templatetags，新建文件 custom.py

# -*- coding:utf-8 -*-
import jieba

from django import template
from app.consts import SensitiveWord

register = template.Library()

@register.filter
def sample_check(value):
    cut_message = jieba.lcut(value)
    print(cut_message)
    print(SensitiveWord)
    
    check = list(set(cut_message) & set(SensitiveWord))
    if len(check) != 0:
