Django Invalid Form-CodePudding

I have a modal with a form in it. The issue is that on invalid form it does return the form errors but it also closes the modal dialog box by rendering the home page again. It is also the home page so the return render is needed for the logging in.

How would I just return to the screen if the post fails.

def index(request):
    context = {}
    if request.method == "POST":
        print(request.POST)
        form = UserProfileForm(request.POST or None, request.FILES or None,instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('home') 
    else:
        form = UserProfileForm()
    context['form']= form
    return render(request, "home.html", context)

modal

{% block content %}
 
    <div  id="editProfile" tabindex="-1" role="dialog" aria-labelledby="editProfilelCenterTitle" aria-hidden="true">
        <div  role="document">
            <div >
                <div >
                    <h5  id="editProfileLongTtitle">Edit Profile</h5>
                    <button type="button"  data-bs-dismiss="modal" aria-label="Close"></button>
                </div>
                <div >
                    {% include 'form.html' %}
                </div>
            </div>
        </div>
    </div>

{% endblock %}

form.html

{% block content %}

    <form method = "POST" action='.' enctype="multipart/form-data">
        {% csrf_token %}
        {{ form.as_p }}
        <button type="submit">Upload</button>
    </form>

{% endblock %}

home.html

{% extends 'base.html' %}

{% block title %}Home{% endblock %}

{% block content %}
  {% if user.is_authenticated %}
  <div > 
    {% include 'editProfileModal.html' %} 
    <div class='row'>  
      {% include 'sidebar.html' %}
    </div> 
  </div> 
  {% else %}
    <p>You are not logged in</p>
    <a href="{% url 'login' %}">Log In</a>
    <a href="{% url 'signup' %}">Sign up</a>
    
  {% endif %}

{% endblock %}

You need shows the modal while you're sending a POST request and the view don't send the redirect. You can try the next poor solution. It's ugly but can work:


def index(request):
    context = {'is_post': False}
    if request.method == "POST":
        context['is_post'] = True
        form = UserProfileForm(request.POST or None, request.FILES or None,instance=request.user)
        if form.is_valid():
            form.save()
            return redirect('home') 
    else:
        form = UserProfileForm()
    context['form']= form
    return render(request, "home.html", context)

{% block content %}
 
    <div  id="editProfile" tabindex="-1" role="dialog" ... >
        <!-- your content ... -->
    </div>
    <!-- Do this after jQuery loaded -->
    {% if is_post %}
    <script type="text/javascript">
        $(window).on('load', function() {
            $('#myModal').modal('show');
        });
    </script>
    {% endif %}
{% endblock %}

You can simple return HttpResponse with form errors.

from django.http import HttpResponse

if form.is_valid():
   ...
else:
   return HttpResponse(form.errors.as_json())

Try this:

def index(request):
context = {}
if request.method == "POST":
    print(request.POST)
    form = UserProfileForm(request.POST or None, request.FILES or None,instance=request.user)
    if form.is_valid():
        form.save()
        return redirect('home') 
context['form']= form
return render(request, "home.html", context)
