I have a form class like this, if the db is not populated I skip that 
field, in the future when something thaat might trigger a d population 
happens and I try to render this form, it doesn't recognise the update, but 
once I restart the development server it renders with the newly added 
field? Is this how it's supposed to happen?  How Can I overcome this? In 
production I cant just start/stop the server right?  can anyone help me 
with this? Thank you

class Schedule(...):

           try:
mails = forms.ModelChoiceField(queryset=FetchFrom.objects.all(),
to_field_name="mail",empty_label=None,initial=FetchFrom.objects.latest("id"
))
except Exception as e:
mails=None
