Post data Query Dict - Why not a list ?

[Szabo, Patrick (LNG-VIE)]

Hi,

 

If i do

 

for key in request.POST.keys():

print request.POST[key]

 

Over this (which is the result of print request.Post):

 

<QueryDict: {u'hix': [u'Monatsreport'], u'my_choice_field': [u'2', u'29', u'42']}>

 

I get:

 

Monatsreport

42

 

Should I not get  lists ?

 

i.e:

 

[Monatsreport]

[2,29,42]

 

I need those other information from  'my_choice_field' how do I get them ?

 

Help would be much appreciated.

 

Best regards

No, multidicts generally conform to the dict interface (mapping a
key to a value) as it's the most useful way to interact with POSTDATA
(or GETDATA for that matter): people will generally map a single value
to each key and having to unpack that value all the time is a pain.

If you want to get all values for the key, as the documentation
indicates[0] you should use the `getlist` method.

Also, having a form to parse and validate the POST data is really the way to go. Even if you never actually show the form to the user, for example in an AJAX callback, deferring all that responsibility and just use "form.is_valid()" and "form.cleaned_data" is a lot better than doing parameter validation in the view.

I may be misunderstanding something, but for one reason lists are not ordered, so you'd never know which item to get, agreed?

Cheers,

Lists are ordered, I think you are confusing something :)
