I assume you already put your sanitized notifications in
<% if notice %> <div id="notice"> <%= notice.html_safe %> </div> <% end %> <%= yield %>
if not, you did this now. Now you can make use of them in all views - I guess it’s best practice. All what’s left to do is to send a special param with your link_to method, when needed, here the param name is
<%= link_to 'New Unit', estate_owners_path(@estate, flash_notice: "please keep in mind ...") %>
Simply catch the param in the approriate view (or globally) :) I use
flash.now instead of
flash as this shows the message only one time and only for the page you were sending the link to.
<% flash.now[:notice] = params[:flash_notice] if params[:flash_notice] %>
With this method you can make your users’ interactions much better, with a few lines of code.
