Django编辑栏目

一 编辑mysite/article/views.py，添加编辑的视图处理函数

@login_required(login_url='/account/login')
# 保证视图只能接受通过POST方式提交的数据
@require_POST
@csrf_exempt
def rename_article_column(request):
    column_name = request.POST["column_name"]
    column_id = request.POST['column_id']
    try:
        # 根据column_id查询到数据，并建立实例对象
        line = ArticleColumn.objects.get(id=column_id)
        # 实现对该对象的重新赋值功能
        line.column = column_name
        # 保存到数据库
        line.save()
        return HttpResponse("1")
    except:
        return HttpResponse("0")

二 编辑mysite/article/urls.py

url(r'^rename-column/$', views.rename_article_column, name="rename_article_column"),

三 编辑前端页面mysite/templates/article/column/article_column.html，新增编辑逻辑

{% extends "article/base.html" %}
{% load staticfiles %}
{% block title %}article column{% endblock %} {% block content %}
<div>
    <p class="text-right">
        <button id="add_column" onclick="add_column()" class="btn btn-primary">添加栏目</button>
    </p>
    <table class="table table-hover">
        <tr>
            <td>序号</td>
            <td>栏目名称</td>
            <td>操作</td>
        </tr>
        {% for column in columns %}
        <tr>
            <td>{{ forloop.counter }}</td>
            <td>{{ column.column }}</td>
            <td>
                <a name="edit" href="javascript:" onclick="edit_column(this, {{ column.id }})">
