(Django) Why messages.success after posting form appears in admin page not in actual user page?

I have form and views. After submitting form post, display message(alert pop-up) appears in admin page, not in actual user page. I cant understand why?

views.py

def node_config(request):
    form = forms.NodeConfigForm
    if request.method == 'POST':
        form = forms.NodeConfigForm(request.POST)
        if form.is_valid():
            form.save()
            messages.success(request, "Configuration successfully submitted")
            return HttpResponseRedirect(reverse('nodes:config'))
    return render(request, 'nodes/nodeconfig.html', {'form': form})

forms.py

from . import models

class NodeConfigForm(forms.ModelForm):
    class Meta:
        model = models.NodeConfigLog
        fields = [
                'nodes',
                'command_logs',
        ]
        labels = {
                'nodes': 'Choose Nodes',
                'command_logs': 'Enter Commands'
        }

The messages will accumulate until they are displayed. If your user template doesn't utilize a mechanism to display messages, then they'll show up on the first page that does. All of the default admin pages display all outstanding messages.

Aaa, my fault. Missed that part. Thank you! Ok, after submitting it appears, but how to make it deletable by clicking on it?

There isn't a built-in manner to delete by clicking on them. They will disappear automatically on the next page load.

But after submitting, it redirects to default page (the same page) automatically and forms are cleared, message appears. So no solution to delete display message without refreshing that page or going to another page?

Correct. No built-in solution. You must refresh the page or navigate to another page. It's a style/feature of Django.

There are other ways to change the behavior in the browser, such as adding some jQuery to alter the display. In this StackOverflow answer there is a snippet to hide the message after a given time period.

Yes, it works, message disappears automatically after configurable time. But it doesnt allow to apply CSS together with that JQuery script.

Not sure why CSS can't be applied as you wish. I don't recall jQuery and CSS being incompatible.
