@caoguangyao it's hard to tell without the actual traceback but I suppose you're creating a ModelDefinition
everytime the view is accessed. ModelDefinition
has a unique constraint on app_label
and object_name
which prevents duplicate model definitions. You might want to use get_or_create
instead of create
and only create the CharField
definition if the model_def
was created. Something like the following should do:
model_def = ModelDefinition.objects.get_or_create(
app_label='app',
object_name='MyOtherModel',
defaults={'fields': [CharFieldDefinition(name='char_field', max_length=25)])
)
from django-mutant.
yes,I forget refresh the data and created it many times
from django-mutant.
