Thanks Tom for this info I have adjusted the models .py as such..
from django.db import models
class ModelManagerReadOnly(model.Manager):
def update(self, *args, **kwargs):
pass
class ModelReadOnly(models.Model):
objects = ModelManagerReadOnly() # The ReadOnly manager.
def save(self, *args, **kwargs):
pass
#raise NotImplemented
def delete(self, *args, **kwargs):
pass
class Meta:
managed = False
abstract = True
class AppLog(ModelReadOnly):
log_no = models.AutoField(db_column=u'LOG_NO') # Field name made
lowercase.
module_id = models.CharField(max_length=25, db_column=u'MODULE_ID') #
Field name made lowercase.
user_name = models.CharField(max_length=25, db_column=u'USER_NAME') #
Field name made lowercase.
full_name = models.CharField(max_length=80, db_column=u'FULL_NAME') #
Field name made lowercase.
description = models.CharField(max_length=3500,
db_column=u'DESCRIPTION', blank=True) # Field name made lowercase.
date_time_stamp = models.DateTimeField(db_column=u'DATE_TIME_STAMP') #
Field name made lowercase.
class Meta(ModelReadOnly.Meta):
db_table = u'APP_LOG'
