Django 1.4 - how to display a success message on form save

[Sithembewena Lloyd Dube]

Hi everyone,

I have a form on which I'm calling save() and if it is successful I would like to display 'your post has been saved' or similar in the template. How would one go about that in Django 1.4?

I am sifting through the docs and cannot seem to find a definitive answer.

Thanks in advance.

you may use HttpResponseRedirect to redirect to another page to display the successful message

Hi,

have you checked the messaging framework in Django?

@newkedison, thank you for the suggestion. I wish to stay on the page without doing any redirects.

@Jirka - thanks. I saw something about the messaging framework and even tried one example which did not work.

I ended up doing the following (which worked):

In view:

success = default value here

    if form.is_valid():

    form.errors['success'] = 'Saved'

....

return self.render_to_response(request, template_name, {

            'tomatoes': tomatoes,

            'success': success,

        })

... and in template:

<p>{{ success }}</p>

Regards.

I did do:

#if form.save():

    success = form.errors['success']

Using the messaging framework is actually very simple.

You need to enable the messaging framework (see the steps here:
https://docs.djangoproject.com/en/1.4/ref/contrib/messages/ )

In your template, you need this (I have that in my base template so
it's included in all pages):

{% if messages %}
{% for message in messages %}
{{ message }}
{% endfor %}
{% endif %}

Obviously, you'll need some formatting/CSS around it.

And in your views.py (or forms.py, ...)

from django.contrib import messages

if form.is_valid():
messages.success(request, 'Your form was saved')

And that's it!

Go with @JirkaV suggestion, also, you can add some jquery effect so that the div appears then fades out on success or on error... its pretty simple and really great!

We do it all over our site. I use class-based views but you can checkout my "MessageMixin". I have the code on this stackoverflow page:

http://stackoverflow.com/questions/5531258/example-of-django-class-based-deleteview/10903943#10903943

It will show up wherever you send the user to next, as long as your template is coded to display the message.

But the message gets displayed only after I reload the page, the page isn't updated.

I'm pretty sure you have to use AJAX to display the message without reloading.
