Upload multiple files using Files Field in Django Admin

Question

Here i have class models:

models.py

class Parameter(models.Model):
    files = models.FileField(
        upload_to='uploaded',
        blank=True,
        null=True,
    )

and i have this in my admin.py

class ParameterAdmin(admin.ModelAdmin):
    form = Parameter

and i add it in my forms.py so it can select more then one file

class ParameterForm(forms.ModelForm):
    def __init__(self, *args, **kwargs):
        super(ParameterForm, self).__init__(*args, **kwargs)
        self.fields['files '] = forms.FileField(
            widget=forms.ClearableFileInput(attrs={'multiple': True}),
        )

But, after i try to choose and select multiple files via django admin.. Not all files are uploaded and it only upload one latest selected file..

How can i upload multiple files via django admin..? I don't need views.py and html from.. i just need django admin can upload multiple files.. Simple

Answer 1

You should override save_model function of ParameterAdmin like this:

def save_model(self, request, obj, form, change):
    files = request.FILES.getlist('files')
    for f in files:
        instance = Parameter(files=f)
        instance.save()

It will save all files.

Answer 2

A FileField only stores a single file. If you want multiple files, you need either multiple fields (but unless each of those files as a distinct specific role it's a bad design) or a distinct ParameterFile model with a foreign key on Parameter and a FileField, and then use an InlineModelAdmin.
