python - ImageField doesnt work -



python - ImageField doesnt work -

when seek upload file gives me template error, required fill in. code: models:

class ahoja(models.model): image = models.imagefield(upload_to='smayat')

forms:

class ahojaform(modelform): class meta: model = ahoja exclude = ()

view:

def testview(request): if request.method == 'post': # pokud form byl odeslan form = ahojaform(request.post, request.files) # formular s daty if form.is_valid(): form.save() #vytvoří událost homecoming httpresponseredirect('/hlavni_stranka/kalendar/') else: form = ahojaform() # prázdný formulář homecoming render(request, 'hlavni_stranka/test.html', {'form': form,})

the first thing check enctype attribute in template. docs:

note request.files contain info if request method post , <form> posted request has attribute enctype="multipart/form-data". otherwise, request.files empty.
