CharField + choices + default = fields.E008

[Christopher Schäpers]

Have this as your models.py:

from django.db import models
from django.utils.translation import ugettext_lazy

breakage_status = (
    (ugettext_lazy("In queue"), 'queue'),
    (ugettext_lazy("Processing"), 'proces'),
    (ugettext_lazy("Done"), 'done'),
)

class Breakage(models.Model):
    status = models.CharField(max_length=6, default="queue", choices=breakage_status)

Results in:

(project)kondou:project/ (master✗) $ ./manage.py check
SystemCheckError: System check identified some issues:

ERRORS:
project.Breakage.status: (fields.E008) Invalid 'default' value: Value 'queue' is not a valid choice.

Hi,

Did you mean to do this?

breakage_status = (
    ('queue', ugettext_lazy("In queue")),
    ('process', ugettext_lazy("Processing")),
    ('done', ugettext_lazy("Done")),
)

No I meant it in reverse … It's wrong I just realized. Wondering how this worked out for me in 1.8 … Closing …

I'm afraid it wasn't working correctly in 1.8 and the newly added 'fields.E008' check spotted it.

You might want to investigate if your database doesn't contain 'Done' entry for this field or 'In que' and 'Process' if you're using MySQL which does silent truncation of value when it cannot fit a VARCHAR instead of raising an integrity error.
