os.system is not working properly
i have a django application with flex as front end, i am using
amfgateway for it.
i have a fortran executable file which will create a new file called
predict.dat(say) it will take two input files(input.dat, test) under
my project directory.
my code is like this
os.system("/home/me/mypro/s_test")where s-test is the
executable file.
Inside the python interpretor and inside the interpretor provided by
django it is working properly.
but inside amfgateway.py it is failing by giving the following.
(and also it is creating the output file
without data)
list in: end of file
apparent state: unit 1 named input.dat
last format: list io
lately reading direct formatted external IO
Aborted
Can anybody help me?

Problem with self referencing Foreign key field and mysql InnoDB
I were using Mysql MyISAM. But I want to enable transaction.
So i shifted to InnoDB.
Actually I have one model as below (*designed somebody i can't
change).
class Folder(models.Model):
folder_id=models.AutoField(primary_key=True)
user_name=models.ForeignKey(User)
folder_name=models.CharField(max_length=80)
parent_folder=models.ForeignKey('self')
At some point i want to insert in this table as below:
Folder(user_name_id=1,folder_name="s",parent_folder_id=0)
But it raises one error like this.
IntegrityError: (1452, 'Cannot add or update a child row: a foreign
key constraint fails (`myproject/folder_folder`, CONSTRAINT
`parent_folder_id_refs_folder_id_12515019` FOREIGN KEY
(`parent_folder_id`) REFERENCES `folder_folder` (`folder_id`))')
But with MyISAM there was no problem like this...
Anyways i need Transaction functionality for other tables in the
database.
Is there any solution for this problem. Please Help me.
Thanks
Lima
