Django request get parameters

Question

In a Django request I have the following:

POST:<QueryDict: {u'section': [u'39'], u'MAINS': [u'137']}> 

How do I get the values of section and MAINS?

if request.method == 'GET':     qd = request.GET elif request.method == 'POST':     qd = request.POST  section_id = qd.__getitem__('section') or getlist.... 

Answer 1

You may also use:

request.POST.get('section','') # => [39] request.POST.get('MAINS','') # => [137]  request.GET.get('section','') # => [39] request.GET.get('MAINS','') # => [137] 

Using this ensures that you don't get an error. If the POST/GET data with any key is not defined then instead of raising an exception the fallback value (second argument of .get() will be used).

Answer 2

You can use [] to extract values from a QueryDict object like you would any ordinary dictionary.

# HTTP POST variables request.POST['section'] # => [39] request.POST['MAINS'] # => [137]  # HTTP GET variables request.GET['section'] # => [39] request.GET['MAINS'] # => [137]  # HTTP POST and HTTP GET variables (Deprecated since Django 1.7) request.REQUEST['section'] # => [39] request.REQUEST['MAINS'] # => [137]
