django

Question

我已按应有的方式配置了所有内容，但无法显示数据库中的图像。

settings.py :

STATIC_URL = '/static/'
MEDIA_URL = '/media/'

MEDIA_ROOT = os.path.join(BASE_DIR, 'media')

STATICFILES_DIRS = (
    os.path.join(BASE_DIR, 'static'),
)

models.py

class Etudiants(models.Model):
    numeroetudiant = models.BigIntegerField(db_column='numeroEtudiant', blank=True, null=True)  # Field name made lowercase.
    nom = models.CharField(max_length=255, blank=True, null=True)
    prenom = models.CharField(max_length=255, blank=True, null=True)
    groupe = models.BigIntegerField(blank=True, null=True)
    photo = models.ImageField(blank=False, null=False, upload_to='images/')
    email = models.CharField(max_length=255, blank=True, null=True)

    class Meta:
        managed = False
        db_table = 'etudiants'

    def __str__(self):
        return self.nom + " " + self.prenom

views.py :

def ajoutetudiant(request): 
    submitted = False
    if request.method == "POST":
        form = EtudiantsForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return HttpResponseRedirect("../ajoutetudiant/")
    else: 
        form = EtudiantsForm()
        if 'submitted' in request.GET:
            submitted = True
    
    return render(request, 'ajoutetudiant.html', {'form': form})

urls.py（我的项目）：

from django.contrib import admin
from django.urls import path, include
from django.conf import settings
from django.conf.urls.static import static

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('notes.urls')),
]+ static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

.html :

<img src="{{etudiant.photo.url}}"/>

图片保存在我的数据库中，如您所见。但无法显示它。

我在 mySQL 数据库中的字段是“blob”。如果它不应该是 blob 我应该放什么？

Answer 1

您 photo 的 MySQL 字段应该是：

`photo` varchar(100) NOT NULL,

django - 无法显示从 mySQL 数据库上传的图像

djano - can not display an uploaded image from mySQL database

django-models

django-views

django-templates
