Instance Method Details

#product_filters_for(products, options = {}) ⇒ Object

Display various filters for the given products including :

- Product categories filters (:category)
- Manufacturer filters (:manufacturer)
- Price filter (:price)
- Properties filters (:property)

Those filters allow automatically searching into the provided products and should only be provided a list of prodcts that can be displayed for the current products list. e.g. for the brands#show products list, we pass the filters all the products from the manufacturer.

In Stall, it is handled by the @filterable_products instance variables from the ProductCategoriesController, ManufacturersController and ProductsController.

By default, all available filters (which contains possible results) are shown. If you need to remove a filter, you can pass an option with its name as false. The following would remove the category filter :

product_filters_for(@filterable_products, category: false)

If, at the opposite, you need to force the display of a certain filter even if there’s no results available, you can do the following :

product_filters_for(@filterable_products, category: { force: true })
