Hi Ken,
You are getting this error because you are missing this line in your
template: {{ formset.management_form }}
Take a look into the documentation:
https://docs.djangoproject.com/en/1.8/topics/forms/formsets/#using-a-formset-in-views-and-templates
You need to carry the information to your second view. If you don’t include
first_name and last_address as fields in the second form, the information
won’t get to your second view, when you post. That’s why I suggested
rendering them as hidden inputs. Your Checkbox form also need to have the
fields.
This is what I mean:
class NameForm (forms.Form):
first_name = forms.CharField (required = False)
last_name = forms.CharField (required = False)
class CheckBox (NameForm):
overwrite = forms.BooleanField (required = False)
And on the template:
<tr>
<td>{{ info.first_name }}</td>
<td>{{ info.last_address }}</td>
<td class="center"><input type="checkbox" name='overwrite' value
="1"></td>
</tr>
<input type=“hidden” name=“first_name” value=“{{ info.first_name
}}”>
<input type=“hidden” name=“last_address” value=“{{
info.last_address }}”>
Let me know if this helps.
cheers,
