Hi, mr.freeze I have a litle problem, with web2py 1.81.5 and webgrid(2010-07-09) I can do this In Model

db.define_table("pagos",
    Field("nota", 'integer', requires=IS_NOT_EMPTY(error_message='No puede estar vacio'), label='No. de Nota'),
    Field("pago", "double", requires=IS_NOT_EMPTY(error_message='No puede estar vacio')),
    Field("saldo", "double", default=0,writable=False),
    Field("vendedor",db.vendedores, requires=IS_IN_DB(vendedores,'vendedores.id','%(names)s %(apelPater)s %(apelMater)s')),
    Field('entregado','boolean', default=False),
    Field('entregadoEl', 'datetime', default=request.now, label='Entregado el'),
    Field("observaciones","string"))

In Controller

@auth.requires_membership('Capturista')
def lee_entregas():
    Capturista = db(db.capturistas.creadoPor==auth.user.id).select()[0]
    db.pagos.vendedor.represent = lambda vendedores: vendedores.names
    grid = webgrid.WebGrid(crud)
    grid.datasource = db((db.pagos.vendedor==db.vendedores.id)&(db.vendedores.regional_id==Capturista.regional_id))
    grid.pagesize = 50
    grid.enabled_rows = ['header','filter','pager','footer']
    grid.fields = ['pagos.nota','pagos.pago','pagos.saldo','pagos.entregadoEl','pagos.vendedor']
    grid.field_headers = ['Nota','Pago','Saldo','Entregado','Vendedor']

    grid.crud_function = 'data' # Set the function where crud will be exposed.
    grid.action_links = ['view']
    grid.action_headers = ['Ver']

    grid.filters = ['pagos.nota']
    grid.filter_items_query = lambda field: (db.pagos.vendedor==db.vendedores.id)&(db.vendedores.regional_id==Capturista.regional_id)

    grid.view_link= lambda row: A('view', _href= crud.url(f='show_entrega', args=[row['pagos']['id']]))

    crud.settings.controller = 'entregas'

    return dict(gridpag=grid())

But with web2py 1.81.5 and webgrid(2010-07-26), I get error in this line grid.view_link= lambda row: A('view', _href= crud.url(f='show_entrega', args=[row['pagos']['id']])) Can I do something to avoid that error?
