I have a Django Form where users inserts numeric values. I am sending the Ajax to a url but I keep receiving:

TypeError: addlog() missing 1 required positional argument: 'id'

I have tried to add the id in the url I got:

Reverse for 'addlog' with arguments '(2,)' not found. 1 pattern(s) tried: ['workout/addlog/\\Z']

Here is the views:

def addlog(request, id):
    workout = get_object_or_404(Workout, id=id)
    url = request.META.get('HTTP_REFERER')
        active_session = ActiveSession.objects.get(id=ActiveSession.objects.last().id)
    if request.headers.get('x-requested-with') == 'XMLHttpRequest' and request.method == 'POST':
        form = LogForm(request.POST)
        if form.is_valid():
            data = Log()
            data.log_workout = request.POST.get('log_workout')
            data.save()  
            context = {
                'log_workout': data.log_workout,
                 'id': workout.id,
            }
            html = render_to_string('my_gym/log_form.html', context, request=request)
            return JsonResponse({'form': html})
        else:
            print("The errors in addlog:",form.errors.as_data())
    else:
        print("What happened??")
    return HttpResponseRedirect(url)

Here is the form:

    <form  action="{% url 'my_gym:addlog' object.id %}" method="post">
        {% csrf_token %}
    </form>

Here is the script:

<script type="text/javascript">
    $(document).ready(function(event){
        $(document).on('click','#submitlog', function(event){
            event.preventDefault();
            var log_workout = $('#id_log_workout').val();

            $.ajax({
                type:'POST',
                url:'{% url 'my_gym:addlog' object.id %}',
                data:{'log_workout' : log_workout, csrfmiddlewaretoken':'{{csrf_token}}'},
                dataType:'json',
                success:function(response){
                    $('#log_form').html(response['form']),
                    console.log($('#log_form').html(response['form','div']));
                },
                error:function(rs, e){
                    console.log(rs.responseText);
                },
            });
        });
    });
</script>

Here is the url:

    path('workout/addlog/<int:id>', addlog, name='addlog'),

Here is the traceback:

My question

How can I fix this error knowing that I tried changing the workout.id to object.id still same error.

CodePudding user response：

There should be id in form instead of object.id since you are passing id from view so:

<form  action="{% url 'my_gym:addlog' id %}" method="POST">

Note: Always add / at the end of route so in urls.py it should be path('workout/addlog/<int:id>/'...)

CodePudding user response：

You did add id to the template's context

context = {
                'log_workout': data.log_workout,
                 'id': workout.id,
            }

So just change :

<form  action="{% url 'my_gym:addlog' object.id %}" method="post">

to :

 <form  action="{% url 'my_gym:addlog' id %}" method="post">
