💡 Hint

Common Mistakes

Using 'upload' which is not the default input name.

Using 'image' or 'document' without matching the form input.

The key used in request.FILES matches the name attribute of the file input in the HTML form. Commonly, it is 'file'.

💡 Hint

Common Mistakes

Using 'read' which reads the whole file at once.

Using 'readlines' which is for text files line by line.

The chunks() method reads the uploaded file in small pieces to avoid memory issues.

Fill both blanks to create a Django form field that accepts file uploads and validates the file size.

Django

from django import forms

class UploadForm(forms.Form):
    file = forms.[1](required=True)

    def clean_file(self):
        file = self.cleaned_data.get('file')
        if file.size > [2]:
            raise forms.ValidationError('File too large')
        return file

💡 Hint

Common Mistakes

Using CharField which is for text input.

Setting size limit as 1000000 which is close but not exact 1MB.

FileField is used for file uploads in forms. The size limit is set in bytes; 1048576 bytes equals 1MB.

5fill in blank

hard

Fill all three blanks to write a Django view that saves an uploaded file using the default storage system.

Django

from django.core.files.storage import [1]

@csrf_exempt
def upload_view(request):
    if request.method == 'POST' and request.FILES.get('file'):
        uploaded_file = request.FILES['file']
        fs = [2]()
        filename = fs.[3](uploaded_file.name, uploaded_file)
        return HttpResponse(f'File saved as {filename}')
    return HttpResponse('Upload a file')

Drag options to blanks, or click blank then click option'

Csave

Dstore

💡 Hint

Common Mistakes

Using 'store' which is not a method of FileSystemStorage.

Using a different storage class not imported.

FileSystemStorage is the default storage class. The save() method saves the file and returns the filename.
