On your second attempt, the problem is that you are trying to call the datetime module, not the datetime class. Change it to datetime.datetime(...) and you should be fine there. _Nik On 5/8/2012 4:12 PM, Lachlan Musicman wrote: > Hola, > > I have a model Person with a dob = models.DateField() >

cleaned_data should return the value of the field, not the index. Did you create your own clean__fieldname method? On Tue, May 8, 2012 at 11:35 AM, francescortiz wrote: > You have to make sure that the javascript code that populates the second > select box sets the value

Re: how to get text of a ChoiceField populated with ajax
