Thanks Mladen for menioning the the import os, I wasn't aware of this.
As for (2), I was using the original approach to try to be as
unobtrusive as possible to JS from HTML (we're trying assign
developers to cookie-cut each area: models for DBAs, controllers for
Pythonists, and HTML/CSS for designers, but if the controllers should
be manipulated then I guess there is no choice? I was trying NOT to
manipulate the web2py_ajax.html directly, only having it including a
JS file that will be included in it. I'm not sure what the security or
load consequences there are which is why i'm asking for feedback.
Sorry I didn't included this snippet in the web2py_ajax.html to
illustrate my point:
>>>
function web2py_ajax_init() {
{{include '../static/jquery_dynamic.js'}} // import individual lines
that manipulate IDs and CLASSES from Views files.
});
<<<<<
I don't directly write the web2py_ajax file but the include file. Is
this possible?
Thanks again.
