Unable to write to database

[William Nash (Bill)]

I'm new to django and I'm trying to learn as I program a small website for 
my scuba diving business.   I'm running into a error that when I try to add 
a diver the database does not update.  When I goto 
http://localhost:8000/add_diver/add_diver/  I'm able to add a diver. 

My code is located at:  https://github.com/wrnash1/ascubadiving

Thanks for any help on this application.

Django Translation won't work

[sebasti...@gmail.com]

I use django translation. Normal works perfect but now i have a problem. 
All verbose name are in english in django code. I setting.py i have as 
second language DE configure. Then i have in models.py:

condition_link = models.ForeignKey(related, null=True, blank=True, 
default=None, on_delete=models.CASCADE,verbose_name=_('Condition'),
   related_name="condition_link")

in django.po in DE Language i don't find anything with 

msgid "Condition"

in form.py i have:

evalfield = self.Meta.model._meta.get_field('condition_link')
self.fields['condition_link'] = 
forms.MultipleChoiceField(choices=evalfield.choices,
widget=SelectMultiple(),
label=evalfield.verbose_name)

and i get in evalfield.verbose_name a translation which are don't exists in 
django.po file. I also delete django.mo file and make django-admin 
compilemessages --locale DE so .mo file is new created.

Same thing.

Then next problem on django translation i have a translation:

#: catalogue/models.py:81
msgid "Gender"
msgstr "Geschlecht"

in frontend msgstr Geschlecht are shown both in english and in german 
language...

99% other translation works right...

Have anyone a idea what it could be? This is absolut strange
