passing dictionary in URL not working. I Get a string

[António Ramos]

hello i have this in a view

<li>{{=A(amostra,_href=URL(r=request,c='amostra',f='get',vars={'amostra':amostra,'amostra_detalhe':Amostra[amostra]}))}} 

Amostra is a dictionary

amostra is every element in Amostra 

every amostra of Amostra is a dictionary

in this view i iterate over Amostra[amostra]['param1....paramN], etc with no problem.

in the controler amostra, function get i do 

print type(request.vars['amostra_detalhe'])

and i get <'str'>  and not <'dict'>

what the hell,

this way i cannot iterate over the params and get this error

string indices must be integers

Please help me.i´m stuck

thank you

António

request.vars is simply a representation of a URL query string, which is a collection of key=value items, where key and value are both treated as strings.

You could presumably encode a dict into a string and decode it when it comes back, but you'll have to do that yourself (and the URL will be pretty ugly).

So what is the best way to pass a dictionary from one page to the other?

can i do session.dictvar=mydictvar?

thank you

Yes, as long as everything you put in there can be pickled.

Do you plan to save the data to the DB or elsewhere at some point? I would suggest putting it in the DB or stuffing it insto session. The JSON thing is more for inter-application communication.
