@Diez - I had been using a wrapper class that just build dicts to pass
to templates w/o subclassing Widget. I suppose I should start
learning how to code Widgets anyway. Still, just for future
reference, lets say you just wanted to pass a boolean to JS using JSON
w/o using the Widget class. It seems to me that since JSON is
basically just a collection of strings, you have to have something on
the JS side that would be dedicated to looping through all passed JSON
values and looking for some true/false string_flag
Otherwise, no
matter what you do, JS can never tell a Boolean from a String just by
looking at the JSON. Your example just ignores the JSON entirely and
manipulates the template directly. Just wondering if there was
another way...
I don't fully understand that, but I fear you don't understand JSON, and
it's usage (or lack of) for your use-case.
Instantiating the jqgrid has *nothing* todo with JSON. It's all about
creating a javascript object, and pass that as options. JSON happens to
be a subset of the javascript object literal notation - so you can (if
you get in through a ajaj-request) simply eval it.
However, in your case, there is no JSON involved.
And you want to modify a jqgrid object afterwards, which has even less
todo with JSON, it's pure & simple javascript.
options.colModel[0].editable = true
can't be expressed in JSON. You can create a javascript-object (which
incidentially is JSON, because it uses no expressions, just literals)
{"colModel" : [{"editable" : true}]}
which you could then pass as options-parameter if jqgrid allows that.
All in all I'd say your problem is simply creating javascript. I showed
you one way, you can of course simply write it into the template if you
prefer. And there is a toscawidgets js-abstraction which I rarely used,
as it gave me errors in earlier versions, but it sort of makes you write
python-code that emits the corresponding JS, with proper literals such
as true and false.
