Question

I have been having some trouble getting a Django SessionWizardView to submit data to my database and I am trying to isolate the issue.

I note from the Form documentation

As well as its elements, a form must specify two things:

• where: the URL to which the data corresponding to the user's input should be returned
• how: the HTTP method the data should be returned by

and

Form data sent back to a Django Web site is processed by a view, generally the same view which published the form. This allows us to reuse some of the same logic.

Currently I am using <form action="/surveyone/" method="post"> which I believe is correct.

The issue is that my view is called class SurveyWizardOne(SessionWizardView): but if I try to use this in the form action I get an error as soon as I click Next on the first page of the survey.

Question: Based on the below is action="/surveyone/" correct?

Thanks

Since your form is submitting to the same url, you can simply use action="" . If you prefer, you can use action="/surveyone/"

If you don't want to hardcode the url in your template, then you need to name your url patterns :

url(r'^surveyone/$', SurveyWizardOne.as_view([
                                             SurveyFormIT1,
                                             SurveyFormH,
                                             ...
                                             ]), name="survey_one"),  

You can then use the url tag in your template:

action="{% url 'survey_one' %}"
