定制will_paginate渲染

Question

Documentation缺乏对will_paginate自定义渲染：

有没有文档如何编写自己的链接呈现，但源代码是不言自明。潜入它，并有选择地覆盖LinkRenderer的方法来调整它们以满足您的需求。

有没有非官方的文档？

找到一份像样的博客文章custom will_paginate renderer

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

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) { '&hellip;' } 
    %(<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
