Ask HN: Editing relationships in a CRUD app

[InsideTheBox]

In a CRUD app how do you deal with editing a item (entity) with a lot of relationships? I'm talking about UI patterns and maybe some tips.

Right now I'm editing the item relationships in a modal window and they are listed on the same page using DataTables (http://datatables.net). I kinda like recreated their commercial editor plugin using Bootstrap modals.

I'm trying to avoid JS as much as possible but it's hard. I have a RESTful API and I would like to render HTML server-side but is not viable for things like this. In the past I used Mustache in a few projects.

What I have right now:

- Company (the item) - Company contacts - Company products - Company events

And more. I'm having a really bad time making it good both in mobile and desktop. Even the bootstrap 3 modal doesn't work 100% on a few devices.

Don't get me wrong, I can make it "work" but I don't feel like it's a good experience.

It's hard to do this as a single dev. Why can't the users just use my API directly! (I'm only half joking hah)
