Restricting url access in DetailView

[Thiago Luiz Parolin]

I have a form that when submitted (using POST) results in a ListView page. Clicking on the record displayed by ListView opens a detail page (DetailView).

The initial form has a captcha that is validated to access the ListView page, but by using the DetailView url I can access the records without acessing the form.

How can I restrict access to record details so they can only be accessed after accessing the form and ListView?

I think that this can be done using UserPassesTestMixin or similar, but i really don't know how to do this.

Any tip will be helpful.

Thanks and sorry about my bad english.
