Inside the application which has the module in its modules folder all you need is "import mytest"

[Константин Комков]

Check line 8 in error, it already contain import mytest, in another project i can import that module.

The working application has a modules/_init__.py file; does the  excepting app have that?

[Christian Varas]

I'm facing the same issue, did you already found the solution?

Btw, I'm running web2py in my android phone, maybe for me is quite different...

Cheers.

Chris.

For what it's worth, I use a separate import line for each of my modules (but not for system modules), and I use the

from mymod import myfunc1, myfunc2

form of import line.
 
/dps

[Константин Комков]

Christian Varas, I don't find solution.

Dave S, yes I tried import mytest like one line without system modules, and like that:

from applications.application.modules import mytest

Is "mymod" your app name?

[Константин Комков]

from applications.application.modules import mytest

>>>No module named application.modules

from applications.application import mytest

>>>No module named application

from applications import mytest

>>>cannot import name mytest

My modul pass: C:\inetpub\wwwroot\applications\application\modules\mytest.py

[Dave S]

No, "mymod" is my module name, in [web2pydir]/applications/myapp/modules/mymod.py  I am not using dotted notation.

I would try changing your application name from "application" (if that isn't an editorial alias, like "myapp" is), because that may be name conflict within web2py.

/dps

[Val K]

There is 'site-packages' folder, modules that is placed in this folder can be imported in any application just as 'import foo' I think using this folder is better than importing across applications

[Константин Комков]

Dave S, it is as variant, but I think that if I change app name maybe somthing will broken. And links too.

Val K, I have two controllers for enrants bachelor degree and magistracy. That controllers have many identical code and functions. I think it is not so good transfer part of app to another folder.

[Константин Комков]

Dave S, today I rename my app from "application" to "statement". After that in browser I saw: 

invalid function (default/statement). After that I restart server and "statement" start working. Then I tried to import my module, but have error again:

import mytest

>>>No module named statement.modules

[Dave S]

Can you make a minimal app you can post here and that shows the same behavior?

Also, from your traceback can you post the vars and args?

/dps

[Константин Комков]

It's my minimal app - https://drive.google.com/open?id=1db5yxx03Deg4T7YCu813HZWFCarChfQ6

[Константин Комков]

P.S. If you delete comment from default.py controller you can see that app don't work becouse dont have that module.
