问题描述
文档缺少 will_paginate 自定义渲染器:
Documentation is lacking for will_paginate custom renderers:
没有没有文档如何编写自己的链接渲染器,但源代码是不言自明的.深入研究,并有选择地覆盖 LinkRenderer 的方法以根据您的需要进行调整.
There is no documentation how to write your own link renderer, but the source code is pretty self-explanatory. Dive into it, and selectively override methods of the LinkRenderer to adjust them to your needs.
是否有任何非官方文档?
Is there any unofficial documentation?

找到了一篇关于 自定义 will_paginate 渲染器
module ApplicationHelper
# change the default link renderer for will_paginate
def will_paginate(collection_or_options = nil, options = {})
if collection_or_options.is_a? Hash
options, collection_or_options = collection_or_options, nil
end
unless options[:renderer]
options = options.merge :renderer => MyCustomLinkRenderer
end
super *[collection_or_options, options].compact
end
end
然后在初始化程序中
class MyCustomLinkRenderer < WillPaginate::ActionView::LinkRenderer do
def container_attributes
{class: "tc cf mv2"}
end
def page_number(page)
if page == current_page
tag(:span, page, class: 'b bg-dark-blue near-white ba b--near-black pa2')
else
link(page, page, class: 'link ba b--near-black near-black pa2', rel: rel_value(page))
end
end
def gap
text = @template.will_paginate_translate(:page_gap) { '…' }
%(<span class="mr2">#{text}</span>)
end
def previous_page
num = @collection.current_page > 1 && @collection.current_page - 1
previous_or_next_page(num, @options[:previous_label], 'link ba near-black b--near-black pa2')
end
def next_page
num = @collection.current_page < total_pages && @collection.current_page + 1
previous_or_next_page(num, @options[:next_label], 'link ba near-black b--near-black pa2')
end
def previous_or_next_page(page, text, classname)
if page
link(text, page, :class => classname)
else
tag(:span, text, :class => classname + ' bg-dark-blue near-white')
end
end
end
