MongoDB

[José Ricardo Borba]

I'm very busy in these days, but I tried to start a new "installation" from the ground (to test the TIME issue with Mongodb in pydal #170), but even without this correction (i.e, with plain web2py clone from github) I receive the below error message.

I'm simply copy the application folder to the new installation (side-by-side with welcome and examples). With CLI client (mongo) everything works fine.

The welcome app works fine.

I see that pydal tries to connect 5 times. The string to connect to mongo is fine (since is a local install. In production will have an user and a password too...).

Version

web2py™	Version 2.10.4-stable+timestamp.2015.04.26.09.05.21

You should use pymongo 3.0

[José Ricardo Borba]

Allright!

Updating pymongo to version 3.0 solves this up!

Now I take care of the mongo time / pydal issue!

Thanks a lot.

update your local copy of pydal, there are several updates regarding mongo in master branch

Yes, I did!

Thanks for the advice.

But submodule when cloning web2py still doesn't work.
