What I found out while responding to your question - there are several ways to do that
First of all, you need to be sure you nailed Nigel’s solution for pretty URLs.
I see you have been active in the thread Internal Bubble Page re-direct, but that’s the key item you need to make sure that works for you.
Once that’s done and you can get the needed object data displayed on your page based on your URL input, here are at least a couple of options:
The simplest here would probably be using Conditional functionality of the Page.
My way of doing that is that in the same workflow that is fetching the “Path” variable from your URL upon page load to decide which “Movie” to load in your case, should set the state that we can later use for SEO reference purposes.
So if you entered bubbleapp.is/movie_page/mrbean2 , your workflow “When Page is Loaded” should do a search in your DB for an object that is representing that movie (I sometimes create separate fields in the DB specifically for lookup purpose).
So in this case search can look somethingl ike - Do a Search for Movies, Where Movie_URL_title contains “Get Path from page URL” (which in this case is “mrbean2”)
If you set up your data correctly, you will find the Thing (DB Object) that is Mr. Bean movie.
Then as a next step in your workflow you can Set State to Movie_Page of the type Movie and give the result of previous step (Mr.Bean movie).
And in settings of your page, you can put Conditional terms to display the needed SEO params fetched from the object you refer to (in our case - State of the Page you defined in the initial Page Loading WF).
Something like that:
Let me know if that works for you.
