权限管理——页面封装操作
1.不封装：
<body>
{% if "add" in request.permisstion_code_list %}
<a href="">添加</a>
{% endif %}
<table>
{% for foo in data_list %}
<tr>
<td>{{ foo.id }}</td>
<td>{{ foo.name }}</td>
{% if 'del' in request.permisstion_code_list %}
<td><a href="">删除</a></td>
{% endif %}
{% if 'edit' in request.permisstion_code_list %}
<td><a href="">编辑</a></td>
{% endif %}
</tr>
{% endfor %}
</table>
</body>
def userinfo(request):
print(request.permisstion_code_list)
data_list = [
{'id':1,'name':'xxx1'},
{'id':2,'name':'xxx2'},
{'id':3,'name':'xxx3'},
{'id':4,'name':'xxx4'},
{'id':5,'name':'xxx5'},
]
return render(request,'userinfo.html',{'data_list':data_list})
