Adding images to a folder. Django-CodePudding

I am writing a small project on django with an app 'santechnic' and ran into a problem.to In which folder should I upload the images in the model Product so that the get request can find them?

santechnic/models.py

class Category(models.Model):
category_name = models.CharField(max_length=200, default="", primary_key=True)
category_image = models.ImageField(default="", upload_to='upload/images/categories')


class Product(models.Model):
product_name = models.CharField(max_length=200, primary_key=True)
length = models.FloatField(default=0.0)
width = models.FloatField(default=0.0)
height = models.FloatField(default=0.0)
product_image = models.ImageField(default="", upload_to=)
category = models.ForeignKey(Category, on_delete=models.CASCADE)

urls.py

urlpatterns = [
    path('admin/', admin.site.urls),
    path('santechnic/', include('santechnic.urls'))
]

santechnic/urls.py

app_name = "santechnic"
urlpatterns = \[
path('', views.CategoryView.as_view(), name='category'),
path('\<slug:category_name\>/', views.ProductsView.as_view(), name='products'),
path('\<slug:category_name\>/\<slug:product_name\>/', views.ProductDetailView.as_view(), name='detail'),
\]

urlpatterns  = static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)

santechnic/views.py

class CategoryView(generic.ListView):
    template_name = 'santechnic/home.html'
    context_object_name = 'category_list'
    model = Category


class ProductsView(generic.ListView):
    template_name = 'santechnic/products.html'
    context_object_name = 'products_list'
    model = Product

part of settings.py

MEDIA_URL = ''
MEDIA_ROOT = ''

Directory

I've tried generate path:

def generate_path(instance, filename):
    return '%s/upload/images/products/' % instance.category.category_name

But I had exception SuspiciousFileOperation.

Also for example I manually add path 'toilets/upload/images/products' in upload_to and got "GET /santechnic/toilets/toilets/upload/images/products/1.png HTTP/1.1" 404 (here category_name='toilets').

If path is 'upload/images/products' I again get "GET /santechnic/toilets/upload/images/products/1.png HTTP/1.1" 404

Help me, please. How can I solve it?

Did you install Pillow?

pip install pillow

maybe you should Google this and try.

CodePudding user response：

First of all, you don't need to create folder manually for to store images, when you write upload_to in model field, it will create media folder automatically inside your project.

In models.py:

product_image = models.ImageField(upload_to="images/") #after writing this, it will create media/images folder inside your project.

To display this on template:

<img src="/media/{{product_image}}" /> #here image will display.

Note: don't forget to add media url and media root in settings.py file.
