Question

我有一个models.py，我在其中指定了一个包含3 ImageFields和3 CharFields的类。 CharFields包含我想在detail.html中使用的YouTube视频ID。但我不知道我应该如何引用details.html

中的元素

我的models.py

from django.db import models

class Feat(models.Model):
    feat_name = models.CharField(max_length=200,default="feature1")
    feat_img1 = models.ImageField(upload_to="%Y/%m/%d",default="1992/08/92")
    feat_img2 = models.ImageField(upload_to="%Y/%m/%d",default="1992/08/92")
    feat_img3 = models.ImageField(upload_to="%Y/%m/%d",default="1992/08/92")
    feat_vid1 = models.CharField(max_length=200,default="3NQRhE772b0")
    feat_vid2 = models.CharField(max_length=200,default="XU3h3CVI_gI")
    feat_vid3 = models.CharField(max_length=200,default="vqHIQD4_lu4")
    num = models.IntegerField(default=0)

def __str__(self):              
  return self.feat_name

view.py

from django.shortcuts import get_object_or_404, render
from django.http import HttpResponseRedirect, HttpResponse
from django.core.urlresolvers import reverse
from django.views import generic
from .models import Feat


class IndexView(generic.ListView):
    template_name = 'feature/base.html'
    context_object_name = 'latest_feat_list'

    def get_queryset(self):
        return Feat.objects.order_by('-num')[:1]

class DetailView(generic.DetailView):
    model = Feat
    template_name = 'feature/detail.html'

base.html

{% if latest_feat_list %}
<ul>
{% for feat in latest_feat_list %}
<a href="{% url 'feature:detail' feat.id %}"><img src="{{    feat.feat_img1.url }}" alt="ac/dc">
<a href="{% url 'feature:detail' feat.id %}"><img src="{{ feat.feat_img2.url }}" alt="ac/dc">
<a href="{% url 'feature:detail' feat.id %}"><img src="{{  feat.feat_img3.url  }}" alt="ac/dc">
{% endfor %}
</ul>
{% else %}
<p>No </p>
{% endif %}

detail.html

{% for `condition` %}
<img id="hide" src="http://img.youtube.com/vi/{{ choice.feat_vid1  }}/hqdefault.jpg" data-video="https://www.youtube.com/embed/{{ choice.feat_vid1  }}?autoplay=1" width="480" height="300"/>
<img id="hide" src="http://img.youtube.com/vi/{{ choice.feat_vid2  }}/hqdefault.jpg" data-video="https://www.youtube.com/embed/{{ choice.feat_vid2  }}?autoplay=1" width="480" height="300"/>
<img id="hide" src="http://img.youtube.com/vi/{{ choice.feat_vid3  }}/hqdefault.jpg" data-video="https://www.youtube.com/embed/{{ choice.feat_vid3  }}?autoplay=1" width="480" height="300"/>


{% endfor %}

我的申请urls.py

from django.conf.urls import url

from . import views

urlpatterns = [
 url(r'^$', views.IndexView.as_view(), name='base'),
 url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),

]

我需要在Feat中显示detail.html类中传递的所有ID，但不知道如何引用Feat中的元素。

我已尝试实施

The function is to display three images and when the user clicks over any of them a video related to that image is displayed. I'm sure it can be done more efficiently but I've just started out and this seemed alright.Help me out?

它与你所做的有点不同，但仍然...... 我不会描述代码，因为它需要很长时间，但我很乐意回答你的任何问题。另外，我强烈建议你阅读关于django模型的文档。

models.py ：

from django.db import models


class Feat(models.Model):
    title = models.CharField(max_length=150)
    image = models.ImageField(upload_to='path/')
    youtube_link = models.URLField()
    created = models.DateTimeField(auto_now_add=True)

    class Meta:
        verbose_name = "Feat"
        verbose_name_plural = "Feats"

    def __str__(self):
        return self.title

views.py ：

from django.shortcuts import get_object_or_404, render
from django.http import HttpResponseRedirect, HttpResponse
from django.core.urlresolvers import reverse
from django.views import generic
from .models import Feat


class IndexView(generic.ListView):
    template_name = 'feature/index.html'
    context_object_name = 'latest_feats'

    def get_queryset(self):
        return Feat.objects.order_by('-created')

class DetailView(generic.DetailView):
    model = Feat
    template_name = 'feature/detail.html' 
    context_object_name = 'feat'

index.html ：

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
    {% if latest_feats %}
    <ul>
        {% for feat in latest_feats %}
        <a href="{% url 'feature:detail' feat.id %}"><img src="{{ feat.image.url }}" alt="some text"></a>
        {% endfor %}
    </ul>
    {% else %}
    <p>No </p>
    {% endif %}
</body>
</html>

detail.html ：

<!DOCTYPE html>
<html>
<head>
    <title></title>
</head>
<body>
<iframe width="560" height="345" src="{{ feat.youtube_link }}" frameborder="0" allowfullscreen></iframe>
</body>
</html>

urls.py ：

urlpatterns = [
    url(r'^$', views.IndexView.as_view(), name='index'),
    url(r'^(?P<pk>[0-9]+)/$', views.DetailView.as_view(), name='detail'),
]

有许多不美观的事情。例如，实现模板继承会更好，但我认为现在这些就足够了。
