【中文标题】数据表 + JSON + best_in_place【英文标题】:Datatables + JSON + best_in_place 【发布时间】:2015-12-17 20:51:13 【问题描述】:我无法将 gem best_in_place 添加到我的表中。
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' for ClassDatatable:0xa9283a44)

捆绑安装完成!
如果我在页面上这样做:
<% Class.all.each do |record| %>
<%= best_in_place(record, :name) %>
<% end %>
这行得通。 但是,该方法不起作用“def data”
【问题讨论】:
你需要显示 gemfile 你完成bundle install
了吗?
正如我在 appliction.js 行中所说的 // = 需要 best_in_place
【参考方案1】:
明白了! 需要在文件class_datatable.rb的开头添加delegate best_in_place部分
【讨论】:
【参考方案2】:对于任何努力寻找正确委派方式的人来说,这就是它的完成方式:
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
