Django -- How to call a form submit view into dataupload view

I have a Form submission view and a dataupload view. I want to save the form and be redirected to the upload page to upload the file.

I tried return the form submission view in the upload view. The form is getting saved but i am getting MultiValueDictKey error


def uploaddata(request):

        return Metadata_submission(request)

        if request.method == 'POST':

                form = uploadmetaform(request.POST, request.FILES)
                if form.is_valid():
                        form.save()
                        return redirect('file_list')
        else:
                form = uploadmetaform()
        return render(request, 'uploaddata.html', {
                'form': form
        })

This is my form submission view:

def Metadata_submission(request):
        print("Metadata Submitted")

        Authors_Name = request.POST["Authors_Name"]
        Affliations = request.POST["Affliations"]
        Dataset_Creation_Date = request.POST["Dataset_Creation_Date"]


        Metadata_var = Metadataform(Authors_Name=Authors_Name, 
        Affliations=Affliations,Dataset_Creation_Date=Dataset_Creation_Dat)
        Metadata_var.save()

MultiValueDictKeyError at /uploaddata/ 'Authors_Name'

You have to use MultiValueDict's get method. It gives a default value if the contents don't exist. The default value would be false in this case.

Authors_Name = request.POST.get("Authors_Name", False)

Edit: I see someone posted before me the same thing and you said it didn´t work. I would suggest then adding:

from django.core.files.storage import FileSystemStorage

file = request.FILES['file_name']
filesystem = FileSystemStorage()
filename = filesystem.save(file.name, file)
form.save()

In local_settings.py:

#The url that you want to use in your browser to prefix all uploaded file paths.
MEDIA_URL = '/path/wherever'
#Here you indicate the absolute path
MEDIA_ROOT = os.getcwd() + "/same/path/"

This media folder should have a chmod 755 for DJANGO to be able to store files there.

Edit 2: Changed MEDIA_URL explanation based on dirkgroten's answer.

Try this:

Authors_Name = request.POST.get('Authors_Name', False)
