Django'；区块'；标记名称'；内容'；多次出现

我在制作应用程序时遇到了这个错误，我想问题出在我的login.html中，因为它指向了错误表。是因为我有2个{%block content%}冲突吗？谢谢你帮助我

TemplateSyntaxError at /login/

'block' tag with name 'content' appears more than once

Request Method:     GET
Request URL:    http://127.0.0.1:8000/login/
Django Version:     1.4.3
Exception Type:     TemplateSyntaxError
Exception Value:    

'block' tag with name 'content' appears more than once

Error during template rendering

In template C:\djcode\mysite\drinker\templates\login.html, error at line 21
'block' tag with name 'content' appears more than once
11  <div class="register_div">

13  <p><label for="password"{% if form.password.errors %} class="error"{% endif %}>Password:</label></p>
14  <p>{{ form.password }}</p>

是的，错误很明显：您有两个名为“content”的块

---

老实说，我不明白你在做什么，因为第二个区块似乎与第一个区块完全相同。您也不能有两个

扩展
标记。
您可以在后端做您想做的事情，即：-Python。
例如，您可以执行以下操作：-

# views.py::
if something is True(any condition for that matter)
msg = "something"

else:
msg = "Something else"

# template, it is here -- index.html::
{% block title %}{{msg}}{% endblock title %}

我习惯于先用谷歌搜索我的错误消息，然后再考虑它们，因为这样明显的错误消息太少了（我是django的新手），但我必须承认这一点非常清楚……如果我想在同一模板中用if语句分隔两个相同的块，该怎么办？这可能吗？@torostar不，还是不可能。您将得到相同的错误。
