I'm trying to upload multiple images with ajax request, i'm using modelformset_factory to upload several images , here is my code :

class Document(models.Model):
    booking =models.ForeignKey(Booking,on_delete=models.PROTECT)
    docs = models.ImageField(upload_to=upload_docs)

my forms.py

class UploadDocumentsForm(forms.ModelForm):
    class Meta:
       model = Document
       fields = ['docs']

my views.py

@login_required
def add_new_image(request,id):
    obj = get_object_or_404(Booking,id=id)
    if request.is_ajax() and request.method == 'POST':
        images = UploadDocumentFormSet(request.POST,request.FILES)
        if images.is_valid():            
            for img in images:
                if img.is_valid() and img.cleaned_data !={}:
                    img_post = img.save(commit=False)
                    img_post.booking = obj
                    img_post.save()
            return JsonResponse({'success':'success'})
        else:
            messages.error(request,_('error message'))

    images = UploadDocumentFormSet(queryset=Document.objects.none())
        
    return render(request,'booking/add_img.html',{'obj':obj,'images':images})

and here is my template includes html and ajax

$('#addButton').click(function() {
     var form_dex1 = $('#id_form-TOTAL_FORMS').val();
        $('#images').append($('#formset').html().replace(/__prefix__/g,form_dex1));
    $('#id_form-TOTAL_FORMS').val(parseInt(form_dex1)   1);    
        
 });   
    
    
const formData = new FormData()
    formData.append('csrf',document.getElementsByName('csrfmiddlewaretoken').value);
    formData.append('docs0',document.getElementById('id_form-0-docs').files[0]);
    formData.append('docs1',document.getElementById('id_form-1-docs').files[0]);
    formData.append('docs2',document.getElementById('id_form-2-docs').files[0]);
    formData.append('docs3',document.getElementById('id_form-3-docs').files[0]);

    const form = document.getElementById('docs-uploader-form')
    form.addEventListener("submit",submitHanler);
    function submitHanler(e){
        e.preventDefault();
        $.ajax({
            type:'POST',
            url:"{% url 'booking:add_new_image' id=2222 %}".replace(/2222/,parseInt({{obj.id}})),
            data:formData,
            dataType:'json',
            success:successFunction,
                        
        })        
    }
    function successFunction(data){
        // console.log(data)
            form.reset();
            alertify.success('added new image')

    } 

<button id="addButton" class="px-4 py-1 pb-2 text-white focus:outline-none header rounded-xl">
            {% trans "add new image" %}
 </button>  
<form action="" method="POST" enctype="multipart/form-data" dir="ltr" id="docs-uploader-form">{% csrf_token %}

                {{images.management_form}}
                <div class="form-group mt-3" id="images">

CodePudding user response：

you have to get the files like this :

  images = request.FILES.getlist('images')
  for image in images:
      photo = Photo(
          name='test',
          image=image,
      )
      photo.save()

  

CodePudding user response：

In your ajax code, you missed setting the contentType and processData to false, this is needed when you use a FormData object with jQuery.ajax

$.ajax({
    type:'POST',
    url:"{% url 'booking:add_new_image' id=2222 %}".replace(/2222/,parseInt({{obj.id}})),
    data:formData,
    dataType:'json',
    processData: false,
    contentType: false,
    success:successFunction
                
});
