該應用程序未在file.html中顯示圖片-Django，Python

Question

我在django-app中將照片插入到我的file.html中時遇到問題。 我試圖進行許多更改，但是圖片仍然沒有顯示。 我將不勝感激。

我的html文件

{% extends 'base.html' %}

{% block title %}
<h2>Home templates</h2>
{% endblock %}

{% block content %}
<div class="container">
{% for frond_photo in frond_photo_list %}
{% if frond_photo.image %}
<img src="{{frond_photo.image.url}}" class="img-responsive" />
{% endif %}
{% endfor %}
{% endblock %}

views.py

def frond_photo_list(request):
    queryset = Frond_Photo.objects.all()
    context = {
        "photos": queryset,
    }
    return render (request, "reviews/home.html", context)

Models.py

class Frond_Photo(models.Model):
    title = models.CharField(max_length=100)
    text = models.CharField(max_length=200)
    image = models.FileField(null=True, blank=True)

urls.py（應用程序）

...
url(r'^home/', views.frond_photo_list, name='home'),
...

admin.py

class Frond_PhotoAdmin(admin.ModelAdmin):
    model = Frond_Photo
admin.site.register(Frond_Photo)

當我的文件如下所示時（一切正常）。 顯示圖片，我可以根據需要進行調整。 我想我不得不忘記一些簡單的事情...

models.py

class Wine(models.Model):
    name = models.CharField(max_length=200)
    image = models.FileField(null=True, blank=True)


    def average_rating(self):
        all_ratings = [list(map(lambda x: x.rating, self.review_set.all()))]
        return np.mean(all_ratings)

    def __unicode__(self):
        return self.name

views.py

def wine_list(request):
    wine_list = Wine.objects.order_by('-name')
    context = {'wine_list':wine_list}
    return render(request, 'reviews/wine_list.html', context)

html的

...
{% if wine_list %}
{% for wine in wine_list %}
{% if wine.image %}
<img class="thumbnail"  src="{{wine.image.url}}" alt="Card image cap"  style="width:100%" width="100" height="250" >
{% endif %}
...

Answer 1

在您的上下文中，將queryset設置為名稱photos但在模板中嘗試遍歷frond_photo_list 。 如果將模板中的for循環行更改為：

{% for frond_photo in photos %}

您應該得到想要的結果。
