Trim Extra

This extra removes the page=1 param from the link of the first page. You need only to require the extra in the initializer file.

This extra is needed only for very specific scenarios, for example if you need to avoid frontend cache duplicates of the first page.

Synopsis

See extras for general usage info.

In the pagy.rb initializer:

require 'pagy/extras/trim'

# it will trim without any further configuration,

# you can disable it explicitly for specific requests
@pagy, @records = pagy(Product.all, trim_extra: false)

# or...

# disable it by default (opt-in)
Pagy::DEFAULT[:trim_extra] = false   # default true
# in this case you have to enable it explicitly when you want the trimming
@pagy, @records = pagy(Product.all, trim_extra: true)

Files

• trim.rb

Variables

Variable	Description	Default
:trim_extra	enable or disable the feature	true

You can use the :trim_extra variable to opt-out of trimming even when the extra is required (trimming by default).

You can set the Pagy::DEFAULT[:trim_extra] default to false if you want to explicitly pass the trim_extra: true variable in order to trim the page param.

Methods

The trim extra overrides the pagy_link_proc method in the Pagy::Frontend module.

pagy_link_proc(pagy, link_extra=’’)

This method overrides the pagy_link_proc using the pagy_trim to process the link to the first page.

pagy_trim(pagy, link)

Sub-method called only by the pagy_link_proc method, it removes the the :page_param param from the first page link (usually page=1).

Override this method if you are customizing the urls.

If you use a pagy_*nav_js helper you should customize also the Pagy.trim javascript function.
