Django 无法在配置文件页面中显示我们的详细信息？

我已经用Django创建了一个项目。登录和注册工作正常，但我无法在配置文件页面上显示模型

用户

数据，我尝试了很多方法，但信息无法显示。仅显示与管理员用户相关的数据

views.py

 def maas(request,maas_username_slug):
   context_dict = {}

   try:
      maas = Maas.objects.get(slug=maas_username_slug)
      context_dict['maas_username'] = maas.username
      context_dict['maas_username_slug'] = maas_username_slug
      context_dict['maas_phone'] = maas.phone
      context_dict['maas_firstname'] = maas.firstname
      context_dict['maas_lastname'] = maas.lastname
      context_dict['maas_location'] = maas.location
      context_dict['date_of_birth'] = maas.date_of_birth
      context_dict['comments'] = maas.comments
      context_dict['maas_gender'] = maas.gender
      context_dict['photo'] = maas.photo
      context_dict['maas'] = maas
   except Maas.DoesNotExist:
      pass
   print(context_dict)
   return render(request, 'testapp/profile.html', {'context_dict': context_dict})

url.py

url(r'(?P<maas_username_slug>\w+)/$', views.maas, name='profile'),

profile.html

{%extends 'testapp/base.html'%}
{%block body_block%}
<h1>Profile page</h1>
<h1>{{ maas_username }} welcome to your profile page</h1>

<li>{{maas_username}}</li>
<li>{{maas_phone}}</li>
<li>{{maas_lastname}}</li>

{%endfor%}

{%extends'testapp/base.html%}
{%block body_block%}
个人资料页
{{maas_username}欢迎来到您的个人资料页面
{{maas_username}}
{{maas_phone}}
{{maas_lastname}
{%endfor%}

重命名

context\u dict

为

context

，作为回报

render（请求'testapp/profile.html'，context）

还有一件事，如果您的

try block fail

，则

上下文将为None

，因此它是

不打印任何内容

更新

def maas(request,maas_username_slug):
   context_dict = {}

   try:
      maas = Maas.objects.get(slug=maas_username_slug)
      context_dict['maas_username'] = maas.username
      context_dict['maas_username_slug'] = maas_username_slug
      context_dict['maas_phone'] = maas.phone
      context_dict['maas_firstname'] = maas.firstname
      context_dict['maas_lastname'] = maas.lastname
      context_dict['maas_location'] = maas.location
      context_dict['date_of_birth'] = maas.date_of_birth
      context_dict['comments'] = maas.comments
      context_dict['maas_gender'] = maas.gender
      context_dict['photo'] = maas.photo
      context_dict['maas'] = maas
   except Maas.DoesNotExist as ex:
      # if your code get exception than context_dict will be none.
      # that's why in html their is nothing to print.
      # I said it above 
      context_dict['error'] = ex
   print(context_dict)
   return render(request, 'testapp/profile.html', context=context_dict)

在

html中

<h1>Profile page</h1>
<h1>{{ error }} </h1> <!-- here if error occured than error message will pring -->
<h1>{{ maas_username }} welcome to your profile page</h1>

<li>{{maas_username}}</li>
<li>{{maas_phone}}</li>
<li>{{maas_lastname}}</li>

Profile页面
{{error}}
{{maas_username}欢迎来到您的个人资料页面
{{maas_username}}
{{maas_phone}}
{{maas_lastname}

这是因为模板上的上下文与您的期望不一样。在这种情况下，您可以在模板上访问以下值：

{%extends 'testapp/base.html'%}
{%block body_block%}
<h1>Profile page</h1>
<h1>{{ context_dict.maas_username }} welcome to your profile page</h1>

<li>{{ context_dict.maas_username}}</li>
<li>{{ context_dict.maas_phone}}</li>
<li>{{ context_dict.maas_lastname}}</li>

{%endfor%}

或：

希望有帮助

而不是

<h1>{{ maas_username }} welcome to your profile page</h1>

<li>{{maas_username}}</li>
<li>{{maas_phone}}</li>
<li>{{maas_lastname}}</li>

{{maas_username}欢迎来到您的个人资料页面
{{maas_username}}
{{maas_phone}}
{{maas_lastname}

您需要将这些更改为：

<h1>{{ context_dict.maas_username }} welcome to your profile page</h1>

<li>{{context_dict.maas_username}}</li>
<li>{{context_dict.maas_phone}}</li>
<li>{{context_dict.maas_lastname}}</li>

{{context\u dict.maas\u username}欢迎来到您的个人资料页面
{{context_dict.maas_username}
{{context_dict.maas_phone}
{{context_dict.maas_lastname}

---

原因是您正在传递字典（单个对象），因此如果您将dict名称命名为“context”，则需要尝试检索它的键值 那可能是

{% for context in context %}
<h1>{{ context.maas_username }} welcome to your profile page</h1>
<li>{{ context.maas_username}}</li>
<li>{{ context.maas_phone}}</li>
<li>{{ context.maas_lastname}}</li>
{% endfor %}

{上下文%中上下文的%
{{context.maas_username}欢迎来到您的个人资料页面
{{context.maas_username}
{{context.maas_phone}
{{context.maas_lastname}
{%endfor%}

模板代码在哪里？请检查我保存的模板代码。当我使用Maas.objects.all（）时。我可以在配置文件上显示数据，但所有用户的数据都将从数据库中显示。我只需要当前登录用户的详细信息。您的打印语句是否显示您正在拾取记录？'testapp/profile.html'已替换为'template\u url'对吗？我已更改但未显示您是否已检查它是否与正在呈现的模板相同。只需在执行HTTPResponse在视图中，并向我显示输出的数据，不在模板中显示控制台上的任何数据，也不打印任何内容。尝试打印

maas

和

mass\u username\u slug

i uesd return render（请求，'testapp/profile.html'，context=context\u dict），但不打印annthing

print（context\u dict）

您是否看到控制台上打印的此变量？我只是担心基本模板中可能不存在该块，所以我认为您可以先将其移出块的一侧进行测试，然后@manuHow about

maas\u username\u slug

？它包含任何值吗？如果是，则问题是数据库中没有与您的查询匹配的Mass对象。没有maas\u username\u slug不包含任何仅在views OnlyOW中提到的值。。你能告诉我你用来访问那个视图的url吗？我想知道如果没有

maas\u username\u slug

，您如何访问该视图。

<h1>{{ maas_username }} welcome to your profile page</h1>

<li>{{maas_username}}</li>
<li>{{maas_phone}}</li>
<li>{{maas_lastname}}</li>

<h1>{{ context_dict.maas_username }} welcome to your profile page</h1>

<li>{{context_dict.maas_username}}</li>
<li>{{context_dict.maas_phone}}</li>
<li>{{context_dict.maas_lastname}}</li>

{% for context in context %}
<h1>{{ context.maas_username }} welcome to your profile page</h1>
<li>{{ context.maas_username}}</li>
<li>{{ context.maas_phone}}</li>
<li>{{ context.maas_lastname}}</li>
{% endfor %}
