If you just want to hide the field use:
-- <%= f.hidden_field :post_id, value: params[:id] %>
See - http://api.rubyonrails.org/classes/ActionView/Helpers/FormHelper.html#method-i-hidden_field

Thanks, last night I tried this in the _form partial:
<%= f.text_field :post_id, value: params[:id] %>
This way it is work, but I wouldn't like to show this to user, I'd like
to do it automatically. How can I do that?
