How can I add several files at once in Django admin?

edit

In Django admin, you can add several files at once by using the Django Multiuploader app. To use this app, follow the steps below:

1. Install the Django Multiuploader app using pip:

pip install django-multiuploader

1. Add 'multiuploader' to your INSTALLED_APPS in settings.py and run the migrations:

INSTALLED_APPS = [
    # other apps
    'multiuploader',
]

python manage.py makemigrations
python manage.py migrate

1. Create a new model for the files you want to upload:

from django.db import models
from multiuploader.models import MultiuploaderImage

class MyFile(models.Model):
    description = models.CharField(max_length=100)
    files = models.ManyToManyField(MultiuploaderImage, blank=True)

    def __str__(self):
        return self.description

1. Create a new admin form for your model:

from django import forms
from multiuploader.forms import MultiuploaderFileForm
from .models import MyFile


class MultiImageForm(forms.ModelForm):
    class Meta:
        model = MyFile
        fields = '__all__'
        widgets = {
            'files': MultiuploaderFileForm()
        }

1. Register your model and form in admin.py:

from django.contrib import admin
from .models import MyFile
from .forms import MultiImageForm


class MyFileAdmin(admin.ModelAdmin):
    form = MultiImageForm

admin.site.register(MyFile, MyFileAdmin)

With the above configuration, you can now upload multiple files at once in Django admin.
