About This Episode
Learn how to link to the current page and add, remove, or modify params in the URL. This is handy for things like search or index pages with filters.
Notes
Resources
For additional security, you should whitelist the params that you want to allow in the links.
# app/helpers/search_helper.rb
module SearchHelper
def current_page_params
# Modify this list to whitelist url params for linking to the current page
request.params.slice("query", "filter", "sort")
end
end
<%= link_to "with foo", current_page_params.merge(foo: true) %>
