Restrictions for modules to include

[realriot]

Hi,

 

I'm trying to include a module within my __init__.py which results in a compile_restricted error...

SyntaxError: Line 68: "_gnquery" is an invalid variable name because it starts with "_"

 

The module works fine in a local testscript.

The module is located within the same directory as the __init__.py script and imported via "import "

 

Any hints?

What module are you trying to import?  Also I believe that you need to put modules you want access to in a Shared Code directory.

[realriot]

Where's the Shared Code directory located?

Where's the Shared Code directory located?

Working fine for me with modules in the code directory

But I guess Gerk is ref. to Contents/Libraries/Shared as seen in the LocalMedia.bundle bundle

And I also think, that you ran into a Plex policy here, but not sure

What module are you trying to import?

  File "/var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-ins/tvheadend-ng.bundle/Contents/Code/__init__.py", line 1, in

    import urllib2, base64, simplejson, time, pyq

I don't know which functions you need, but some of the most basic stuff the urllib2, base64, simplejson and time modules provide are already part of the Plex Framework.

[realriot]

I just wanted to include pyq. A gracenote wrapper for json.

[Gerk]

The Shared Code I was talking about would be a directory within your bundle but I think dane is right that you've hit a restriction here.  What happens if you try to import only pyq (and not the other stuff that's already mostly included in the framework)?

Does your plist file contains:

I suspect the restricted stuff may be a result of trying to import some of the standard stuff that's already included in the framework (but maybe not, hard to say without knowing more details).

Not sure here, since I actually always do the imports as well, and have no errors

I do however think, that  if not running in Elevated mode, the framework will bug down on all functions starting with an _ character, but again just guessing here :blink:

Yep that's possible as well, we're both just guessing as all we've seen are little snippets of logs :)
