Re: Connecting to external databases from Views.py

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'

If you derive a model from a base class, and want the base class's
Meta class to have an effect, you must derive the child class's Meta
class from the base class's Meta class:

https://docs.djangoproject.com/en/1.4/topics/db/models/#meta-inheritance

The net result is that with your current code, the 'managed' attribute
on the Meta class does not exist on the derived classes.

Cheers
