Get an array from a Rails form

Question

I need to design a form for a account resource. In that form, i need to collect some set of ids as an array in the params hash in attribute called

Answer 1

I'm working in something similar. My issue was how to pass the input name to a partial to resolve it as a hash using the rails form_for helper.

So, my solutions was something like this:

= render 'my_partial', form: form, name: "item_ids[item.id]"

So, this gonna render an html like this:

The number 1 is the item.id, this is how HTML understand that you gonna pass an array or hash, all depends your config.

So, the params gonna look like this:

"items_ids"=>{"1"=>"1"}

This is working for me with an form_object + virtus
