Where s my JSON data in my incoming Django request

Question

I m trying to process incoming JSON Ajax requests with Django Python   request is ajax   is True on the request  but I have no idea where the payload is with the JSON data   request POST dir contains this       class        cmp        contains        copy        deepcopy        delattr         delitem        dict        doc        eq        ge        getattribute        getitem        gt        hash        init        iter        le        len         lt        module        ne        new        reduce        reduce ex        repr         setattr        setitem        str        weakref       assert mutable     encoding      get encoding     mutable     set encoding    appendlist    clear    copy    encoding     fromkeys    get    getlist    has key    items    iteritems    iterkeys    itervalues     keys    lists    pop    popitem    setdefault    setlist    setlistdefault    update     urlencode    values     There are apparently no keys in the request post keys   When I look at the POST in Firebug  there is JSON data being sent up in the request

Using Angular you should add header to request or add it to module config headers    Content-Type    application x-www-form-urlencoded     http       url  url      method  method      timeout  timeout      data  data      headers    Content-Type    application x-www-form-urlencoded

The HTTP POST payload is just a flat bunch of bytes  Django  like most frameworks  decodes it into a dictionary from either URL encoded parameters  or MIME-multipart encoding  If you just dump the JSON data in the POST content  Django won t decode it  Either do the JSON decoding from the full POST content  not the dictionary   or put the JSON data into a MIME-multipart wrapper   In short  show the JavaScript code  The problem seems to be there

request raw response is now deprecated  Use request body instead to process non-conventional form data such as XML payloads  binary images  etc   Django documentation on the issue

Its important to remember Python 3 has a different way to represent strings - they are byte arrays   Using Django 1 9 and Python 2 7 and sending the JSON data in the main body  not a header  you would use something like   mydata   json loads request body    But for Django 1 9 and Python 3 4 you would use   mydata   json loads request body decode  utf-8      I just went through this learning curve making my first Py3 Django app

If you are posting JSON to Django  I think you want request body  request raw post data on Django  lt  1 4   This will give you the raw JSON data sent via the post  From there you can process it further   Here is an example using JavaScript  jQuery  jquery-json and Django   JavaScript   var myEvent    id  calEvent id  start  calEvent start  end  calEvent end                 allDay  calEvent allDay      ajax       url    event save-json        type   POST       contentType   application json  charset utf-8       data    toJSON myEvent       dataType   text       success  function result            alert result Result               Django   def save events json request       if request is ajax            if request method     POST               print  Raw Data    s     request body        return HttpResponse  OK     Django  lt  1 4     def save events json request       if request is ajax            if request method     POST               print  Raw Data    s     request raw post data     return HttpResponse  OK

request POST is just a dictionary-like object  so just index into it with dict syntax   Assuming your form field is fred  you could do something like this   if  fred  in request POST      mydata   request POST  fred     Alternately  use a form object to deal with the POST data
