Question

I have a text area in a django based website that displays the content of a database field.
I’d like to be able to edit this field and submit it to a function which updates the field in the database.

I know how I can call a function in a views.py which then send back the result of the query using render_to_response to a new webpage.

So in summary, how do I adress a function in a django/python script using a html form without the need to refer to another url?

It’s usually recommended to use Post/Redirect/Get pattern, for example:

def myview(request, **kwargs):

    if request.POST:
        # validate the post data

        if valid:
            # save and redirect to another url
            return HttpResponseRedirect(...)
        else:
            # render the view with partial data/error message


    if request.GET:
        # render the view

        return render_to_response(...)
