javascript - Django and Ajax - Implementing an Array from Ajax to the template -


currently i'm trying implement ajax django in order refresh sections of web app. i'm having trouble in 2 parts.

  • first getting value input template views.py. seems when passes , print out in cmd sure value passed correctly, none. i'm not sure why going in that. know managed pass correctly when directly views.py without going in javascript file first.
  • secondly don't know how implement view.py returns ajax function in javascript file. mean when whole instruction set in views , return informaation needed ajax, dont know command use implement in template. currenly i'm returning array of chars changes order depending on user input. @ first loading, alphabet in order when user enters number, letters shift according input. got part going i'm stuck @ taking template after been shifted.

also recommendation welcome. if see not right done or implemented in better way, please let me know. code ethics highly appreciated!

my code here:

forms.py

class caesarcipher(forms.form): key = forms.decimalfield(max_value = 26, min_value = 1, initial = 1, required = true) plaintext = forms.charfield(max_length = 8, required = true) letter = forms.charfield(max_length = 1) 

views.py

def caesarhomepage(request): cipher = alphabet() x = cipher.getlistletter() y = cipher.getlistletter()    if request.method == 'post':      form = caesarcipher(request.post or none)      print(request.post.get('id_key')) #this gives none     print(form['key'].value()) # gives none     int(form['key'].value())      y = cipher.setcipherletters(integerkey)       return httpresponse(json.dumps({'y' : y}), content_type="application/json")    form = caesarcipher(request.post or none)  context = { 'x': x,             'y': y,             'form': form, }   return render(request, 'homecaesar.html', context) 

main.js

    $("#keybuttonid").on({ click : function() {     $.ajax( {       url : "http://127.0.0.1:8000/homecaesar/",       type : "post",       data: { csrfviewmiddleware: '{{ csrf_token }}', the_key: $('#id_key').val() },        success : function(json) {         //  $('#id_key').val('0');            console.log(json);           $('#alteredalphabet').append(json); // not work, need change           console.log("function called!");       }      });  } 

});

the first part of problem has nothing ajax. not how access form data. need check form.is_valid(), access data throughform.cleaned_data`.
