Rails add pass variable to create new record from loop

Question

I have models Ticket and Table. Ticket belongs to Table.

I want to show an index of tables, each one should have a button to a new ticket with corresponding table assigned.

tickets controller:

  def new_from_table
    @ticket = Ticket.new(table_id: table_id)
  end

and in my view:

<% @tables.each do |table| %>
  <tr>
    <td><%= table.name %></td>
    <td><%= link_to 'Add', new_from_table_path(:table_id => table.id), class: "btn btn-sm btn-success" %></td>
    </td>
  </tr>

and routes:

  get 'new_from_table', to: 'tickets#new_from_table', as: :new_from_table

But I can't figure out how to pass table.id on loop to ticket.table_id.

Solution above returns:

undefined local variable or method `table_id' for Ticket......

Any suggestion?

undefined local variable or method `table_id' for Ticket......

That means, while table_id is passed with pathnew_from_table_path(:table_id => table.id) at controller#action this parameter table_id will be taken dynamically as params[:table_id]

  def new_from_table
    @ticket = Ticket.new(table_id: params[:table_id])
  end
