I have a local repository and a web2py installation up. how can I change web2py's application directory so that it points to the repository? or how can I let web2py use the repository?

Some weeks ago, I tried to create a symlink inside /applications folder, but I got an error in modules.
I was using mklink command on Win7, and my app works fine when located inside /applications folder without symlink...

Below is the ticket I got. Maybe you have an idea?

Hmmm... I pretty sure in linux a symlink would work, but in win it is different... If I remember there is a difference in hardlink and softlink that need to be consider...

I have found the problem. Thank you Richard!

For Windows users who want to move the applications subfolders out of web2py directory, the correct syntax is :

mklink /J TheLinkName ThePath

mklink /J created a directory junction
Previously, I used mklink /D (which creates a symlink for a folder) but this doesn't work.

Loïc, just a thought... How will you manage the upgrade of web2py version? If you have only a single repo, you will make symlink in new version of web2py applications folder, but then you may face issue with the new version that force you to stick with previous version... If you have commit change over your trunk you will have to revert...

I generally just copy my entire repo, that become a clone...

For Windows users who are interested...

Now I have 2 separate folders :

|_web2py (containing web2py source files with default applications)
   |_...
   |_applications
      |_admin
      |_welcome

|_web2py_apps (folder containing all my apps)
   |_app1
   |_app2
   |_...

When I upgrade web2py , I replace the whole "web2py" folder
Then I launch a little batch file stored in "web2py_apps" to recreate all directory junctions.
Code here :

create_junctions.bat

for /f "delims=" %%a In ('dir /ad/b  "./" ') Do mklink /J ..\web2py\applications\%%a .\%%a
pause

Loic,
I find this to be useful, primarily because I want to add just my web2py applications to source control, and not necessarily the web2py installation. Also, am developing this stuff on windows, and actually deploy it on ubuntu. I feel this separation of my apps from the web2py platform is useful in this sense too.
Some details like:
* Where to run the script from
* Also an additional step would be to script the wget of the web2py install, and follow that up with this script automatically. This is something that could be contributed later on...

Possible for you to add this to web2py slices, as a recipe? (http://www.web2pyslices.com/home).
Thank you.

Loïc, what I was saying is that you will get in trouble when you upgrade web2py with this scenario... Migration from version of web2py to another is sometime not straigh as it should and you found yourself having to go back an forth between both version. In this situation you have sometime to make changes to your app that are not backward compatible so you can't have only one copy of your app in this case at least if you want to be flexible... What I do is to copy my repo from one web2py version to another. My setup is like this :

programmation/version_246/web2py/applications/myapp

programmation/version_247/web2py/applications/myapp

programmation/version_274/web2py/applications/myapp

myapp in each of these web2py version is a clone from the precedent version of web2py. When I feel confortable that I will migrate definitly to a new version I leave the old app behind that sit. It is not that clean, but it had prove to be effective... And if I want to make cleanup I just have to delete the old web2py version tree to make space.

Hope it help.

Richard
