Datatables + JSON + best_in_place

我无法将gem best_in_place添加到我的表中。Datatables + JSON + best_in_place

class_datatable.rb：

def data 
    class.map do |record| 
     [ 
     best_in_place(record, :name), 
     best_in_place(record, :short_name) 
     ] 
    end 
    end

有一个错误：NoMethodError（未定义的方法`best_in_place”的ClassDatatable：0xa9283a44）

捆绑安装完成！

如果我做这样的网页上：

<% Class.all.each do |record| %> 
    <%= best_in_place(record, :name) %> 
<% end %>

工程。但是，该方法不起作用“def数据”

你需要显示gemfile –

你做过“捆绑安装”吗？ – Dusht

正如我在appliction.js行中所说// // require best_in_place – Alexander

了解！有必要在文件class_datatable.rb

的开头添加委托best_in_place部分对于任何人苦苦寻找委派正确的方式，这是它是如何做：

class MyCustomDatatable < AjaxDatatablesRails::Base 
    # either define them one-by-one 
    def_delegator :@view, :link_to 
    def_delegator :@view, :h 
    def_delegator :@view, :mail_to 

    # or define them in one pass 
    def_delegators :@view, :link_to, :h, :mailto, :edit_resource_path, :other_method 

    # now, you'll have these methods available to be used anywhere 
    # example: mapping the 2d jsonified array returned. 
    def data 
    records.map do |record| 
     [ 
     link_to(record.fname, edit_resource_path(record)), 
     mail_to(record.email), 
     # other attributes 
     ] 
    end 
    end 
end
