Final version. Now only import if was not imported before and break
when find the views file due to the fact that i'm using only one view
file per app/module:
def find_and_import(arg, dirname, fnames):
for file_name in fnames:
module_name = os.path.join(dirname, arg)[2:].replace('/', '.')
if file_name == arg + '.py' and not module_name in
sys.modules:
__import__(module_name)
break
os.path.walk('./database', find_and_import, 'views')
thread closed for me. Ty again :)
