thank you Massimo, I wanted to generate valid html and I was not able
to embed, for subcategories, <ul> inside <li> directly using the
web2py html helpers.
It won me this round (time presion), but I build it just as html and
got it working as follow:
def catree():
# Identificando a las categorías raíces o de primer nivel
supercategorias =
db(db.t_categoria.supercategoria==None).select(db.t_categoria.id,db.t_categoria.nombre)
htmlmenu = '<ul id="catree">'
# Generando 1er nivel del árbol de categorías
for supercat in supercategorias:
htmlmenu+='<li class="catree_1">'+supercat.nombre
# Identificando categorías de 2do nivel
cats=db(db.t_categoria.supercategoria==supercat.id).select(db.t_categoria.nombre,db.t_categoria.id)
if cats:
htmlmenu+='<ul>'
# Generando 2do nivel del árbol de categorías
for cat in cats:
htmlmenu+=str(LI(A(cat.nombre,
_href=URL(f=articulo,args=cat.id),cid="caja"), _class="catree_2"))
htmlmenu+='</ul>'
htmlmenu+='</li>'
htmlmenu+='</ul>'
return dict(htmlmenu=XML(htmlmenu))
I love web2py as my only framework, thank you Massimo for build it and
all the community for keep improving it :)
