Forme di Django che si spezzano in IE7

Question

Ho un modulo web dJango da un modello con alcuni errori di verifica (campo email valido, ecc.). Tutto funziona bene in vari browser Opera, Camino, Netscape, Safari e IE (eccetto IE7).

Tutto ciò che ottengo in IE7 è il messaggio 'Internet Explorer non può visualizzare la pagina web'. Se i moduli validi i dati vengono scritti nel database, penso che abbia qualcosa a che fare con lo stage di reindirizzamento.

Ho provato varie cose metodo = invio e invio modulo javascript ma nulla sembra fermare IE7 dandomi questo errore.

Qualsiasi aiuto sarebbe apprezzato.

Conferma che è la fase di reindirizzamento che sta causando il problema sostituendo

HttpResponseRedirect(url) 

con

HttpResponse('<!DOCTYPE html><html><head><title>title</title></head><body><a href="%(url)s">%(url)s</a></body></html>' % {'url':url}) 

Se questo non rende, allora il problema sta accadendo prima del reindirizzamento. Se esegue il rendering, il problema potrebbe essere il reindirizzamento o potrebbe essere la pagina reindirizzata. Clicca sul link. Se la pagina successiva viene visualizzata correttamente, il problema è quasi certamente il reindirizzamento stesso. In caso contrario, il problema è nella pagina reindirizzata.
