FileField not working properly

[FilipeAVS]

Hey all 👋

I'm currently working with the Form Wizard to build a multi-step form. I have 5 steps (hence 5 forms), and on the 4th one I'm trying to add a FileField like this:

attachment = forms.FileField()

Very simple and direct. Also, on my view I added this:

    class FormWizard(SessionWizardView):
        file_storage = FileSystemStorage(location="/media/participation")
        ...

Also nothing too fancy here. For some reason, this is not working. I can select a file on my form and everything, but when I press to go to the next step, the page only refreshes. Like this:

I followed the documentation so am I missing something? Thank you.

I was missing the enctype at the form tag in the template: enctype="multipart/form-data"
