i have json file want read in , stuff using javascript. within django 1.8. end goal use d3 fancy visualization, while django , python power rest of backend.
i having trouble getting data .json file javascript functions. json file 'uk.json'.
here views.py:
# create views here. def index(request): data = get_data() # return jsonify(data) return render(request, 'pages/index.html')#, {'data': json.dumps(data)}) # api view function data def getuk(request): json_data = open('/static/js/uk.json') data1 = json.load(json_data) # deserializes data2 = json.dumps(json_data) # json formatted string json_data.close() return jsonresponse(data2) here corresponding urls.py:
url(r'^$', views.index, name='index'), url(r'^api/getuk', views.getuk, name='getuk'), index.html trying fancy display:
{% load staticfiles %} <!doctype html> <meta charset="utf-8"> <style> /* css goes here. */ </style> <body> <script src="//d3js.org/d3.v3.min.js" charset="utf-8"></script> <script src="//d3js.org/topojson.v1.min.js"></script> <script src="{% static 'js/graph.js' %}"></script> </body> and graph.js want use d3 on json data being passed through.
d3.json("api/getuk", function(error, uk){ if(error) return console.error(error); console.log(uk); }) trying data graph.js can use it. know how without framework, i'm trying work together.
jsonresponse() excepts dict, not json string.
try :
def getuk(request): open('/static/js/uk.json') json_file: json_data = json_file.read() obj = json.loads(json_data) return jsonresponse(obj)
