Django不提供文字内容(首次尝试) [英] Django not serving text content (First attempt)
问题描述
摘要:
此特定Django Web应用程序的目的是仅在主页上显示一些lorem ipsum文本，例如博客文章.Django不提供我的博客文章内容.我知道问题出在我的views.py或urls.py(或两者都有).
The purpose of this particular Django web app is to just show some lorem ipsum text on the home page, like a blog post. Django is not serving my blog post content. I know the problem is either with my views.py or urls.py (or both).
详细信息:
我已经在我的models.py中声明了数据.我有views.py可以实例化模型.我迁移了sqlite，并成功登录到管理控制台，并输入了一些占位符数据.
I’ve got the data declared inside my models.py. I’ve got my views.py to instantiate the model. I migrated sqlite and successfully logged into the Admin Dashboard and entered some placeholder data.
我正试图让Django提供我在管理控制台中输入的占位符内容，但它是空白.
I’m trying to get Django to serve the placeholder content that I entered into the Admin Dashboard, but instead it’s blank.
这是我的测试用例: https://i.imgur.com/IuOl3G4.jpg 要对其进行描述，您可以看到已解析博客文章"，日期"，图像"和正文" HTML标题元素，但没有显示任何内容.
Here is my what my test case looks like: https://i.imgur.com/IuOl3G4.jpg To describe it, you can see The Blog Post, Date, Image, and Body Text HTML heading elements parsed, but none of the content is showing.
这是我的应用的urls.py:
Here is my app’s urls.py:
from django.urls import path, include
from . import views
urlpatterns = [
path('', views.mortems, name='home'),
]
我尝试用 alls/landings 替换第一个path()参数的引号.我尝试将name参数从 home 交换为 mortems .我还尝试使用 mortem (没有 s ).这些更改都无济于事.
I’ve tried swapping out the quotation marks for the first path() parameter with alls/landings. I’ve tried swapping the name parameter from home to mortems. I also tried using mortem (without the s). None of these changes help.
我还尝试了谷歌搜索(有变体):
I've also tried Googling (with variations):
- 正文django未显示模板"
- 'django不显示文本内容'
(其中包括)与哪种声音相关但与我的问题完全不同的SO问题和答案:
Which turned up (among other) SO questions and answers which kind of sound related but are completely different from my issue:
这是我的应用的views.py:
Here is my app’s views.py:
from django.shortcuts import redirect, render, get_object_or_404
from mortems.models import Mortem
def mortems(request):
mortem = Mortem.objects.order_by('-pub_date')
context = {'mortem':mortem}
return render(request, 'alls/landings.html', context)
关于它的价值，这是我的模型中的相关行:
For what it is worth, here are the relevant lines in my model:
class Mortem(models.Model):
title = models.CharField(max_length=161)
pub_date = models.DateTimeField()
image = models.ImageField(upload_to='media/')
body = models.TextField()
now = datetime.datetime.now()
另外，这是我的模板，上面有相关的问题代码行(42-50):
Also, here is my template with the relevant problematic lines (42-50):
<h1> BLOG POST:</h1>
<h4>Date: {{ mortem.pub_date_preference }}</h4>
<br />
Image: <img src="{{ mortem.image.url }}" class="img-responsive center-block" style="max-height:300px;" />
<br />
<!-- Body text should go here : -->
Body Text:
<p>{{ mortem.body|safe }}</p>
完整的源代码在GitHub上.这里是验尸"应用程序源代码.
The full source code is up on GitHub. Here is the 'mortems' app source code specifically.
对于拥有大量时间的大量SO用户，我想我正在接受请求请求.哈哈
For generous SO users with time on their hands, I guess I’m accepting pull requests. haha
推荐答案
我认为您需要将views.py更新为:
I think you need to update the views.py as:
from django.shortcuts import redirect, render, get_object_or_404
from mortems.models import Mortem
def mortems(request):
mortems = Mortem.objects.all().order_by('-pub_date') # returns an iterable queryset
context = {'mortems':mortems} # using plural as it's a list like object
return render(request, 'alls/landings.html', context)
在模板代码中，您需要遍历列表以一次显示一个对象.即
In the template code, you need to iterate over the list to display a single object one at a time. i.e
<h1> BLOG POSTs:</h1>
{% for moertm in mortems}
<h4>Date: {{ mortem.pub_date_preference }}</h4>
<br />
Image: <img src="{{ mortem.image.url }}" class="img-responsive center-block" style="max-height:300px;" />
<br />
<!-- Body text should go here : -->
Body Text:
<p>{{ mortem.body|safe }}</p>
{% endfor %}
