django/ajax: Unable to get Ajax post data in the views.py

I had a problem getting ajax post data from django backend, I don't know how to pass the value, please help. In html I have simply this: ``` <form id="get_vulns_from_family"> <label for="family_content">Enter a family name to display the NVTs</label> <input id="family_content" /> <input type="submit" value="search" /> </form> ``` In javascript I wrote this: ``` $(function() { $("#get_vulns_from_family").submit(function(event) { var family_text = $("#family_content").val(); var family_data = {"family": family_text}; $.ajax({ url: "/template_conf/get_vulns_from_family", type: "POST", data: family_data, success: function(response) { console.log(response); }, error: function(response) { console.log("failed!"); } }); // prevent default posting of form event.preventDefault(); }); }); ``` In Django method corresponding to url `/template_conf/get_vulns_from_family`, I tried this: ``` def get_vuln_from_family(request): family = request.POST['family'] # some other operations to get value for variable "json_data" return HttpResponse(simplejson.dumps(json_data)) ``` But django said: `MultiValueDictKeyError: "Key 'family' not found in <QueryDict: {}>"`, which means the POST dictionary is empty. Am I using the wrong way to get post data? If so what should I do? Thanks.
