Hi All,

I have a web project that involves the following relationship:

Episode has a 1:1 with Plan, and Plan has a 1:Many with Task.

The project is setup in Springboot and Thymeleaf.

Episode has its own webpage for displaying and entering new Episodes. I also have a webpage for displaying and entering plans (havent got to task yet).

In terms of wiring it all up, a plan is accessed form the Episode webpage and will send the user to a new page.

I wanted to check however that the same episode that is in the Episode webpage should be added to the model for the plan page?

Cheers

Al

If you have a web flow made out of multiple steps, then you should have a single Model across all pages. If you have multiple tabs that might operate on the same data, then you could advise the users to submit their pending changes prior to switching to a new table. This way, you can commit the current changes, and always fetch the updated data from the DB.

Thanks Vald,

Good tip about the saving.

Is the passing of the object done through session parameter or by passing it in path or ???

It's usually a good idea to take advantage of the Http Session storage as it's easier to retain a given entity as-is between the read and the write HTTP requests. If you use Java EE, you can even use a Stateful EJB.

If your architecture relies on stateless web containers, then your only option is to marshall entities as JSON on the client side and send them back as POST/PUT parameters back to the server to reconstruct the entities.
