Django request.GET does not contain name of submitted form button

Question

I'm basically having the same issue addressed in a previous question (Django request.POST does not contain the name of the button that submitted the form) but the fix described there does not work.

I am using ajax so that, after submission, I stay on the same page. My page has two forms. The first form has three buttons and I correctly pass the "name" of the button in the GET request. My second form has two buttons but I am unable to pass the "name" of either button in the GET request (the "name" of the input field, however, is in the GET request). I don't know why it's not working. Any ideas?

JS SOLUTION:

$(document).ready(function(){
    console.log("hello from email.js");
    $('.email_citations').submit(function(event){
        console.log("submit email");
        var whichButton = $(".form_button[clicked=true]")[0].value
        console.log("WHICH BUTTON: ");
        console.log(whichButton);
        var email_address = $(this).val();
        var data = $(this).serialize();
        data += "&" + whichButton;
        console.log(data);
        $.ajax({
            data: data,
            type: $(this).attr('method'),
            url: $(this).attr('action'),
            success: function(data){
                console.log("DATA: ");
                console.log(data);
                $('.email_sent_message').html(JSON.parse(data).submit_message);
            }
        });
        return false;
    });
    $(".form_button").click(function() {
        $(".form_button").removeAttr("clicked");
        $(this).attr("clicked", "true");
    });
});

html forms:



    
    
    
  


    
    
    

{{ submit_message }}

My javascript/ajax in an email.js file:

$(document).ready(function(){
    console.log("hello from email.js");
    $('.email_citations').submit(function(event){
        console.log("submit email");
        var clicked_button = $(".form_button[clicked=true]")[0].name;
        console.log(clicked_button);
        clicked_button.push($(".form_button[clicked=true]")[0].value);
        console.log(clicked_button);
        var email_address = $(this).val();
        var data = $(this).serialize();
        data += "&" + clicked_button;
        console.log(data);
        $.ajax({
            data: $(this).serialize(),
            type: $(this).attr('method'),
            url: $(this).attr('action'),
            success: function(data){
                $('.email_sent_message').html(JSON.parse(data).submit_message);
            }
        });
        return false;
    });
    $(".form_button").click(function() {
        $(".form_button").removeAttr("clicked");
        $(this).attr("clicked", "true");
    });
});`

My view:

def email_it(request):
    context = RequestContext(request)
    if request.method == 'GET':
        getdict = request.GET.dict()
        form = EmailCitationsForm(request.GET)
        if form.is_valid():
            context = request.session.get('All_Citations_Context')
            if ('which_citations') in getdict.keys():
                if 'all' in getdict.values():
                    text_template = 'email_allCitations.txt'
                    html_template = 'email_allCitations.html'

                    text_content = render_to_string(text_template, context, context_instance=RequestContext(request))
                    html_content = render_to_string(html_template, context, context_instance=RequestContext(request))

                    msg = EmailMultiAlternatives(subject, text_content, from_email, to)
                    #msg.attach()
                    msg.attach_alternative(html_content, "text/html")
                    msg.send()
                    submit_message = "Thank you. Your citations have been sent via email."

                    return http.HttpResponse(json.dumps({'submit_message': submit_message}))

                if 'selected' in getdict.values():
                   text_template = 'email_selectedCitations.txt'
                   html_template = 'email_selectedCitations.html'

                    text_content = render_to_string(text_template, context, context_instance=RequestContext(request))
                    html_content = render_to_string(html_template, context, context_instance=RequestContext(request))

                    msg = EmailMultiAlternatives(subject, text_content, from_email, to)

                    msg.attach_alternative(html_content, "text/html")
                    msg.send()
                    submit_message = "Your citations have been sent via email."

                    return http.HttpResponse(json.dumps({'submit_message': submit_message}))
            else:
                submit_message = "Something went wrong. Sorry, your email did not send."

        else:
            submit_message = form.errors['email_address']
    else:
        form = EmailCitationsForm()
        submit_message = ""
    return http.HttpResponse(json.dumps({'submit_message': submit_message}))

Ok, this is more of an HTML/jQuery problem than a Django one.

First, your first form works because presumably you let the browser handle the submit. If you use a similar code to the one provided, it does not work.

If you log $(this).serialize() you get precisely what you get on the backend. Check out this answer jQuery: how to get which button was clicked upon form submission?

Notice I've removed the django bits.

$(document).ready(function(){
    console.log("hello from email.js");
    $('.email_citations').submit(function(event){
        console.log("submit email");
        var clicked_button = $(".form_button[clicked=true]")[0].name;
        console.log(clicked_button);
        var email_address = $(this).val();
        var data = $(this).serialize();
        data += "&" + clicked_button;
        console.log(data);
        $.ajax({
            data: $(this).serialize(),
            type: $(this).attr('method'),
            url: $(this).attr('action'),
            success: function(data){
                $('.email_sent_message').html(JSON.parse(data).submit_message);
            }
        });
        return false;
    });
    $(".form_button").click(function() {
        $(".form_button").removeAttr("clicked");
        $(this).attr("clicked", "true");
    });
});
