我创建了一个模型,该模型可以在模型中使用FileField()
接受任何类型的文件。
我已经正确上传了一些文件,并将引用保存在数据库中(如在管理界面中以及“媒体”文件夹中所见)。
但是,无法在模板中渲染此图像。我需要渲染它,这样我的用户才能将它们下载到他们的计算机上。
这些是我的图片的路径:
media/imagenes/468x60.jpg #relative path
/home/ogonzales/Escritorio/web_proyects/gallito/media/imagenes/468x60.jpg #full path

models.py :
class TamaniosCantidades(models.Model):
TAMANIOS = (('2x2', '2" x 2"',), ('3x3', '3" x 3"',),
('4x4', '4" x 4"',), ('5x5', '5" x 5"',))
CANTIDADES = (('50', '50',), ('100', '100',),
('150', '150',))
tamanios = models.CharField(max_length=10, choices=TAMANIOS)
cantidades = models.CharField(max_length=10, choices=CANTIDADES)
imagenes = models.FileField(upload_to='imagenes/')
uploaded_at = models.DateTimeField(auto_now_add=True)
forms.py:
class TamaniosCantidadesForm(forms.ModelForm):
tamanios = forms.ChoiceField(choices=TAMANIOS, widget=forms.RadioSelect(), label='Selecciona un tamaño')
cantidades = forms.ChoiceField(choices=CANTIDADES, widget=forms.RadioSelect(), label='Selecciona la cantidad')
class Meta:
model = TamaniosCantidades
# fields = ['tamanios', 'cantidades',]
fields = ['tamanios', 'cantidades', 'imagenes']
views.py:
def pedidos(request):
pedidos = TamaniosCantidades.objects.all()
return render(request, 'main_app/pedidos.html', {'pedidos': pedidos})
urls.py:
urlpatterns = [
path('', views.index),
path('productos/', views.productos),
path('productos/die-cut-stickers', views.die_cut, name='die-cut-stickers'),
path('post_url/', views.post_treasure, name='post_treasure'),
path('post_url_tamanioscantidades/', views.post_tamanioscantidades, name='post_tamanioscantidades'),
path('pedidos/', views.pedidos),
# path('login/', views.login_view, name='login'),
# path('logout/', views.logout, {'next_page': settings.LOGOUT_REDIRECT_URL}, name='logout'),

HTML:
<div>
<p>Mi Imagen</p>
<img src="/home/ogonzales/Escritorio/web_proyects/gallito/media/imagenes/468x60.jpg">
{% for pedido in pedidos %}
<p> {{ pedido.imagenes }}</p>
<img src="{{ pedido.imagenes.url }}" alt="Smiley">
{% endfor %}
</div>
更新1:
STATIC_URL = '/static/'
STATIC_ROOT = os.path.join(BASE_DIR, 'static')
MEDIA_URL = '/media/'
MEDIA_ROOT = os.path.join(BASE_DIR, 'media')
更新2:
这是呈现的html
<p> imagenes/728x90.jpg</p>
<img src="/media/imagenes/728x90.jpg" alt="Smiley">
<p> imagenes/468x60.jpg</p>
<img src="/media/imagenes/468x60.jpg" alt="Smiley">
答案 0 :(得分:1)
请尝试在URLs.py
中添加以下代码段:
from django.conf import settings
from django.conf.urls.static import static
if settings.DEBUG:
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT).
这应该使您的媒体在开发过程中能够在浏览器中工作。
