Re: django 1.9, migrations SUCK

[ludovic coues]

In /home/ariatel_web/dashboard.ariatel.com.co/apps/did/forms.py, replacing
country = forms.ChoiceField(choices=[ (d.country_name,
d.country_name) for d in DidCountry.objects.filter(is_active=True) ]

with
country = forms.ChoiceField(choices=lambda: [ (d.country_name,
d.country_name) for d in DidCountry.objects.filter(is_active=True) ]

should do the trick. It will make the choices arguments a callable
which will be evaluated when the form is used for the first time, not
when the module is imported.

  File "/home/ariatel_web/dashboard.ariatel.com.co/apps/did/forms.py", line
12, in BuySearchForm
country = forms.ChoiceField(choices=[ (d.country_name, d.country_name)
for d in DidCountry.objects.filter(is_active=True) ], required=False)

Theres your problem, you are trying to query the database when it's empty

This line here is the problem – you should never evaluate querysets at
module level, in this case you should either use a function as the
choices argument to ChoiceField, or use a ModelChoiceField.

Please change your email subject to something more polite.

You have a good chance to get expert help here from people, including perhaps 
people who helped create the Django migrations system - don't be rude about it.

If you're getting errors about missing database tables even when you
run manage.py makemigrations, then that would mean you'll get that
same error every time you run manage.py, regardless of what command
you run. makemigrations does not access the database, it only inspects
existing migration files, and compares them to the current model
definitions.

The error you are getting is most likely because you're accessing the
database on import (i.e. somewhere at module level you are making
database queries). If that is indeed the case, then you would get the
exact same error even with the old syncdb. However, it is hard to tell
for sure, since you have not provided the full traceback.

Cheers,

Michal

django 1.9, migrations SUCK

[Jorge Cadena]

Hi,

I am dev in django at last 4 years, i missed ./manage.py syncdb, 

Delete all tables from databases (MariaDB, PostgreSQL) command line from 
DB, and run python manage.py migrate always same error

*python manage.py migrate*
django.db.utils.ProgrammingError: (1146, "Table 
'dashaboard_web.did_didcountry' doesn't exist")

*python manage.py migrate did*
django.db.utils.ProgrammingError: (1146, "Table 
'dashaboard_web.did_didcountry' doesn't exist")

*python manage.py makemigrations*
django.db.utils.ProgrammingError: (1146, "Table 
'dashaboard_web.did_didcountry' doesn't exist")

*python manage.py sqlmigrate did 0001*
django.db.utils.ProgrammingError: (1146, "Table 
'dashaboard_web.did_didcountry' doesn't exist")

*python manage.py migrate --run-syncdb*
django.db.utils.ProgrammingError: (1146, "Table 
'dashaboard_web.did_didcountry' doesn't exist")


if the tables doesn't exist, why create table new ???
as, create new tables run command python manage.py migrate ??
