Still its giving the same error. I have placed file checkrole.py under
modules/role/checkrole.py
Here is my code in db.py
role=local_import('role')
db=SQLDB('mysql://root:test...@localhost/web')
db.define_table('address',Field('name'),Field('address'))
db.address.name.requires=IS_NOT_EMPTY()
db.address.address.requires=IS_NOT_EMPTY()
And the Error
Traceback (most recent call last):
File "/home/vikarmt/Desktop/web2py/gluon/restricted.py", line 188,
in restricted
exec ccode in environment
File "/home/vikarmt/Desktop/web2py/applications/myapp/models/db.py",
line 1, in <module>
role=local_import('role')
File "/home/vikarmt/Desktop/web2py/gluon/compileapp.py", line 241,
in <lambda>
local_import_aux(name,reload,app)
File "/home/vikarmt/Desktop/web2py/gluon/compileapp.py", line 172,
in local_import_aux
module = __import__(name)
ImportError: No module named role
Any Idea why the error is coming?
Thanks
