Minor fixes needed for generic key name
We no longer try to retreive an entity when there are unset fields.
This sort of makes 'getIfFields' obsolete, since we check if fields
now anyway. This is needed because getKeyFieldsFromDict expects the
fields to be set.
Also a minor fix in a Django template so that the generic 'edit' page
has a working delete button again.
from django.db.backends import BaseDatabaseValidation
class DatabaseValidation(BaseDatabaseValidation):
def validate_field(self, errors, opts, f):
"Prior to MySQL 5.0.3, character fields could not exceed 255 characters"
from django.db import models
from django.db import connection
db_version = connection.get_server_version()
if db_version < (5, 0, 3) and isinstance(f, (models.CharField, models.CommaSeparatedIntegerField, models.SlugField)) and f.max_length > 255:
errors.add(opts,
'"%s": %s cannot have a "max_length" greater than 255 when you are using a version of MySQL prior to 5.0.3 (you are using %s).' %
(f.name, f.__class__.__name__, '.'.join([str(n) for n in db_version[:3]])))
