Question

I have the array

params[:search][:cars]

which contains

"search"=>{"cars"=>["11", "7"]}

this array I am trying to put into the hidden of a form field (this block of code is in the helper method):

...
data += hidden_field_tag 'search[cars]', params[:search][:cars]
...
return data.html_safe

and this form after sending gives me:

"search"=>{"cars"=>"[\"11\", \"7\"]"}

I would like to ask you about the help, how can I send an array through the hidden input.

Thank you

In a view (adapt it to use in your helper) you can write:

<% params[:search][:cars].each do |car_id| %>
  <%= hidden_field_tag 'search[cars][]', car_id %>
<% end %>
