Dans mon application rails, j'essaie d'utiliser des caches imbriqués, mais ma clé de cache n'expire pas lorsque user.profile.full_name
est modifiée. Ainsi, lorsque l'utilisateur change de nom, le nom complet affiché par _profile_product.html.erb
reste l'ancien.rails 4 expiration du cache ne fonctionne pas
Comment changer la clé?
profils/show.html.erb
<% cache(@profile) do %> #this is the profile info and the cache key expires properly when @profile.full_name changes
<%= @profile.full_name %>
.....
<% end %>
<% if @profile.user.products.any? %> #not nested in the previous cache;
#products belonging to the profile are listed with this code under the profile info
<%= render 'products/profile_products' %>
<% end %>
_profile_products.html.erb
<% cache(['profile-products', @profile_products.map(&:id), @profile_products.map(&:updated_at).max]) do %>
<%= render partial: "products/profile_product", collection: @profile_products, as: :product %>
<% end %>
_profile_product.html.erb
<% cache (['profile-product-single', product, product.user.profile]) do %>
<%= product.name %>
<%= product.user.profile.full_name %> #if I change profile name this one won't change thanks to the cache
<% end %>
