I improved the function and put it at
http://www.web2pyslices.com/main/slices/take_slice/46
Features:
- links in every breadcrumb
- can set a breadcrumb to args
- can localize/personalize the controllers - using T()
Thanks to Richard <richardbp(at)gmail.com>, for original function that I
made improvements
Put in your model/module:
[image: Select]
def breadcrumbs(arg_title=None):
"Create breadcrumb links for current request"
# make links pretty by capitalizing and using 'home' instead of 'default'
#pretty = lambda s: s.replace('default', 'Início').replace('_',
' ').capitalize()
menus = [A(T('Home'), _href=URL(r=request, c='default', f='index'))]
if request.controller != 'default':
# add link to current controller
menus.append(A(T(pretty(request.controller)),
_href=URL(r=request, c=request.controller, f='index')))
if request.function == 'index':
# are at root of controller
menus[-1] = A(T(pretty(request.controller)),
_href=URL(r=request, c=request.controller, f=request.function))
else:
# are at function within controller
menus.append(A(T(pretty(request.function)),
_href=URL(r=request, c=request.controller, f=request.function)))
# you can set a title putting using breadcrumbs('My Detail Title')
if request.args and arg_title:
menus.append(A(T(arg_title)), _href=URL(r=request,
c=request.controller, f=request.function,args=[request.args]))
else:
#menus.append(A(pretty(request.controller),
_href=URL(r=request, c=request.controller, f='index')))
if request.function == 'index':
# are at root of controller
#menus[-1] = pretty(request.controller)
pass
#menus.append(A(pretty(request.controller),
_href=URL(r=request, c=request.controller, f=request.function)))
else:
# are at function within controller
menus.append(A(T(pretty(request.function)),
_href=URL(r=request, c=request.controller, f=request.function)))
# you can set a title putting using breadcrumbs('My Detail Title')
if request.args and arg_title:
menus.append(A(T(arg_title), _href=URL(r=request,
f=request.function,args=[request.args])))
return XML(' > '.join(str(m) for m in menus))
To use, put in your view:
[image: Select]
{{=breadcrumbs() }}
or
[image: Select]
{{=breadcrumbs('My Title for request.args ') }}
