sorry, but I didn't get it.
An example:
-------------------------------
name_grid = [("Edit", "id"), ("Name", "name"), ("Birth", "birth")]
class RootController(BaseController):
# some others ...
@expose("genshi:namecollection.templates.names_list")
def list(self, **kw):
"""a simple list for Names"""
names = DBSession.query(Names)
pylons.c.name_grid=DataGrid(fields = name_grid)
pylons.c.name_data=DBSession.query(Names).all()
return dict(names=names, page='Name List')
-----------------------------
I would like to have a link <a href="/edit/value_of_id">Edit</a> in
the resulting grid in stead of the (value of the) id.
What's the code for that?
