inserting related models

Please use ChatGPT to translate your post from your mother tongue.

Thanks for the quick response. I have two models: rc_RendicionDeCuentas and rc_OPIs. The relationship is one-to-many from rc_RendicionDeCuentas to rc_OPIs. My questions are: a) How to display the rc_OPIs form in edit.blade.php when the create rc_OPIs button is selected? b) In the rc_OPIs controller: in store, I first store rc_RendicionDeCuentas and then rc_OPIs, and where do I send the view? /* Model: rc_RendicionDeCuentas*/

That's not clear, I don't understand all what you are talking about.

For a one to many relationship, you have 2 options :

Option 1 - use a form to create only the rc_RendicionDeCuentas without the rc_OPIs, then show the rc_RendicionDeCuentas model and create the different rc_OPIs one per one (both models are created from 2 distinct forms)

Option 2 - use a form to create the rc_RendicionDeCuentas and the rc_OPIs at the same time in the same form, to do that you need to add the fields dynamically for rc_OPIs (via AlpineJS, VueJS, Livewire, ... or whatever technology like these ones)

For option 2, you would have the fields for the rc_RendicionDeCuentas model and in the same form a + button to add fields dynamically for the rc_OPIs models.
