how to extend an existing Admin panel page?

[Brettschneider Falk]

Hi,

while programming on http://trac-hacks.org/wiki/SimpleMultiProjectPlugin this question occurs to us:
Currently, we have an additional page Admin=>Projects=>Components for mapping the components to certain projects. We'd rather use the already existing edit page of Admin=>TicketSystem=>Components to add a multi-selection box for projects there. What is the data manipulation hook for those pages?

There is http://www.edgewall.org/docs/branches-0.12-stable/epydoc/trac.web.api.IRequestFilter-class.html but it doesn't work for us with Admin panels, or we made a simple stupid mistake in using it. We know how to edit the component edit web page on client side, but we need the something we can hook on on server side to let the plugin do its work there.

CU, F@lk

I think you'll want to work with ITemplateStreamFilter, to implement something like this:
 

from genshi.builder import tag
from genshi.filters import Transformer
from trac.core import *
from trac.web.api import ITemplateStreamFilter

class AdminPanelStreamFilter(Component):
    implements(ITemplateStreamFilter)       
   
    def filter_stream(self, req, method, filename, stream, data):
       
        if req.path_info == '/admin/general/logging':
            stream = stream | Transformer("//div[@class='field']//input[@id='log_file']").after(
                tag.input(type='button', value='Browse...'))
       
        return stream

Just wondering how you would propose to do this client side. Using jQuery? (just a guess, I don't know how to go about this using jQuery).
