Inline Entity Form: Optional #save_form as field config option?

My apologies @geek-merlin I wasn't aware you had replied to me. We have editors at work that ofen work on rather large slideshows, and we use IEF to produce minimal forms so they don't have the entire entity to deal with inline. Sometimes (more often than I'm used to) they have browser crashes, and if they don't manually hit the save button every so often they can lose a lot of work, so #save_entity helps in that it auto saves as they complete each section. If their browser crashes, they only lose the one asset they were working on rather than possibly all of them.

Hope that clarifies!

@patpluspun Thanks for clarifying.
I can see the point, and we have the same with all kinds of edit actions.
But the solution feels like a dirty hack. I don't expect the entity to be saved before i hit save.

I see at least 2 viable solutions:
- Add the option to save intermediate results as forward revision on the server.
This can benefit all forms. Maybe there's already a module for it?

- Add the option to save intermediate form state in the browser's local storage.
This can benefit all forms. Maybe there's already a module for it?
(At least there are browser extensions, iirc one is called lazarus.)

Here's another use case.

We're using IEF to allow HR managers to create usuable, onboarding forms (e.g. Media entities) inline.

Even if they do not save the onboarding package, we want this reusable form to still exist (as it exists in our eSignature vendor's database).

Thank you for vetting feature requests and your hard work on this piece of art :)

Patch for the 2.0.x branch.

Making this back to active due to provided use case.

New patch for 3.x

I think this is useful feature for whenever you need access to the inline entity before saving the parent entity. This is the case whenever the parent entity has some dependent value on the inline entity aside from the relationship to the inline entity.

Additionally, providing this option moves more towards a decoupled approached of performing one atomic operation.
