* Prefer empty? to any?.Kasper Timm Hansen2016-02-121-1/+1
| | | | | | | If the collection isn't empty any? will loop through it. Spare the loop and be more concise with what we're asking the collection about.
* Stop mutating return value.Kasper Timm Hansen2016-02-121-2/+3
| | | | | | `PartialRenderer.render_collection_with/without_template` returns an array of rendered partials. Avoid dup'ing and shifting it by indexing into the collection instead.
* Inline `fetch_or_cache_partial`.Kasper Timm Hansen2016-02-121-10/+6
| | | | Wasn't pulling its weight for a simple yield anymore.
* Write to collection cache where the template is rendered.Kasper Timm Hansen2016-02-121-9/+8
| | | | | | | | Moves us closer to having access to a local template variable, we can ask for eligibility and its virtual_path. Currently we rely on `@template`, which we don't have available when rendering collections without a fixed template.
* Only write to collection cache if we have a callable cache key.Kasper Timm Hansen2016-02-121-1/+5
| | | | | | | | | | | A callable cache key writes to the collection cache under a certain namespace. Which means if we don't have scoped cache key we can just rely on the `cache model_name do` in the templates to cache them. Less writes, more sharing. Add `assert_customer_cached` to better illustrate this in tests, and remove tests which then don't communicate as much.
* Remove useless callable_cache_key? check.Kasper Timm Hansen2016-02-121-2/+1
| | | | | | `automatic_cache_eligible?ยด is only called if there was no `:cache` key to fetch in the `@options` via `cache_collection?`. So the check will always be false.
* Remove single_template_render? method.Kasper Timm Hansen2016-02-121-5/+1
| | | | | | Written when I didn't understand the internals as well. Action View generally just refers to `@template` when meaning a fixed template render. So follow that implicit convention.
* Don't search in locals for cache_options.Kasper Timm Hansen2016-02-121-3/+1
| | | | | | We should only support a top level `cache_options`. We also don't have to default the options to a hash as Active Support's cache defaults that arg to nil.
* Fix cache issue when different partials use the same collectionRoque Pinel2015-06-281-1/+1
| | | | | | | | | Adds the `virtual_path` option to `cache_fragment_name` so it can be provided when needed. That allows `cache_collection_render` to get the appropriate cache key with the digest generated based on the template and prevent collision with other templates that cache the same collection.

* Collections automatically cache and fetch partials.Kasper Timm Hansen2015-02-211-2/+15
| | | | | | | | | | | | | | | | | | | | | | | Collections can take advantage of `multi_read` if they render one template and their partials begin with a cache call. The cache call must correspond to either what the collections elements are rendered as, or match the inferred name of the partial. So with a notifications/_notification.html.erb template like: ```ruby <% cache notification %> <%# ... %> <% end %> ``` A collection would be able to use `multi_read` if rendered like: ```ruby <%= render @notifications %> <%= render partial: 'notifications/notification', collection: @notifications, as: :notification %> ```
* Merge multi_fetch_fragments.Kasper Timm Hansen2015-02-201-0/+57
Makes caching a collection of template partials faster using `read_multi` on the Rails cache store. Some caching implementations have optimized `read_multi` so we don't have to check in the cache store for every template.
