How to dynamically set 'name' attribute of a simple form input - ruby-on-rails

Question

I am using Simple Form in a Rails application in which a FormsController controller was defined as follow :
class FormsController < ApplicationController
def index
#forms = Form.all
end
def new
#form = Form.new(form_params)
end
...
private
def form_params
params.require(:form).permit(:user, :name, :tag, :link, :repo)
end
end
A new view is used to get some inputs from user
<div class="form">
<%= simple_form_for #param do |f| %>
<div class="form-inputs";>
<%= f.input :user %>
<%= f.input :name %>
<%= f.input :tag %>
<%= f.input :link %>
<%= f.input :repo %>
</div>
<div class="form-actions">
<%= f.button :submit, "Create", class: "btn-primary" %>
</div>
<% end %>
</div>
I checked what's the generated name for a each field using inspect :
<input type="text" name="form[user]" id="form_user">
Printing parameters in controller while submitting a form returns :
{“user”=>”value1”, “name”=>”value2”, “tag”=>”value3”, “link”=>”value4”, “repo”=>”value5”}
From now, I would like to duplicate that's simple form few times. So, I first updated the field name from form[<parameter>] to form[1][<parameter>]
<div class="form-inputs";>
<%= f.input :user, input_html: { name: 'form[1][user]' } %>
<%= f.input :name, input_html: { name: 'form[1][name]' } %>
<%= f.input :tag, input_html: { name: 'form[1][tag]' } %>
<%= f.input :link, input_html: { name: 'form[1][link]' } %>
<%= f.input :repo, input_html: { name: 'form[1][repo]' } %>
</div>
What I get from now as parameters output is :
"form"=>{"1"=>{"“user”"=>"value1", "“name”"=>"value2", "“tag”"=>"value3", "“link”"=>"value4", "“repo”"=>"value5"}}
What's the best way to dynamically allocate the id to the form[<id>][user] to the field ?
Is it possible to get parameters formatted as follow ?
form => { 1 => {user: "user1" }, 2 => {user: "user2" }, 3 => {user: "user3" }.. }
form => { 1 => {name: "name1" }, 2 => {name: "name2" }, 3 => {name: "name3" }.. }
