Instance Method Details

#cache_key ⇒ Object

Returns the key that’s taken for cache path.

If the page is the current preview it uses the updated_at value as cache key.

def cache_key
  if Page.current_preview == self
    "alchemy/pages/#{id}-#{updated_at}"
  else
    "alchemy/pages/#{id}-#{published_at}"
  end
end

#cache_page? ⇒ Boolean

Returns true if the page cache control headers should be set.

Disable Alchemy’s page caching globally

# config/alchemy/config.yml
...
cache_pages: false

Disable caching on page layout level

# config/alchemy/page_layouts.yml
- name: contact
  cache: false

Note:

This only sets the cache control headers and skips rendering of the page body, if the cache is fresh. This does not disable the fragment caching in the views. So if you don’t want a page and it’s elements to be cached, then be sure to not use <% cache element %> in the views.

Returns:

  • (Boolean)
