将数组 object 从 Ajax 传递到 Django 框架

Question

Ajax code

Assume arry1D has values [0,1,2,3,4]

$.ajax({
  url: "{% url 'form_post' %}",
  type: "POST",
  data: {
    arry1D: arry1D,
    'csrfmiddlewaretoken': tk
  },
  cache:false,

});

Below the code of getModelAttribute() function in view.py

I'm trying to access arry1D[0] element but I could not.

def getModelAttribute(request, self=None):
    print("In Method")
    if request.method == "POST" and request.is_ajax():
        arry1D = request.POST.get('arry1D')
        print(arry1D[0])
        return JsonResponse({'arry1D':arry1D})

Answer 1

to get access to your arry1D array object you need getlist() and not get()

change this line

arry1D = request.POST.get('arry1D')

to

arry1D = request.POST.getlist('arry1D')

refer to this topic https://docs.djangoproject.com/en/3.0/ref/request-response/#django.http.QueryDict.getlist
