Question

我已经使用Django创建了一个项目。登录和注册工作正常，但是我无法在个人资料页面上显示模型User数据，我已经尝试了很多方法，但是没有显示信息。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})

urls.py

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

models.py

from django.db import models
from django.template.defaultfilters import slugify
from django.contrib.auth.models import User

class Maas(models.Model):

    username=models.CharField(max_length=25)
    password = models.CharField(max_length=50)
    phone = models.IntegerField(default=0)
    firstname = models.CharField(max_length=40, blank=True)
    lastname = models.CharField(max_length=40, blank=True)
    location = models.CharField(max_length=40, blank=True)
    email = models.EmailField(blank=True)
    date_of_birth = models.DateField(null=True, blank=True)
    gender = models.CharField(max_length=10, blank=True)
    comments = models.CharField(max_length=500, blank=True)
    photo = models.ImageField(upload_to='media/photos/', null=True, 
    blank=True)
    slug = models.SlugField(unique=True,default="")

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%}

Answer 1

将context_dict重命名为context，并返回render(request, 'testapp/profile.html', context)

还有一件事，如果您的try block fail比context will be None为print nothing

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>

Answer 2

这是因为模板上的上下文与您的期望不同。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%}

我建议您将渲染功能的context_dict设置为context参数，而不是为此创建新字典，或者只需要将context_dict作为第二个参数传递给渲染功能的参数。像这样：

return render(request, 'testapp/profile.html', context=context_dict)

或：

return render(request, 'testapp/profile.html', context_dict)

希望有帮助！

Answer 3

代替

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

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

您需要将其更改为：

<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>

您要传递字典（单个对象）的原因，因此您需要尝试检索其键的值

Answer 4

如果您将您的字典名称命名为“上下文” 那么可能是

{% 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 %}

无法在个人资料页面中显示我们的详细信息？
