我正在关注关于 DataTables 的远程数据的 Railscast。为了让它工作,你创建一个 datatable.rb
我正在尝试定义在 datatable.rb 中的 3 个位置使用的选择
这是代码:
class Workorders3Datatable
delegate :params, :h, :link_to, :number_to_currency, to: :@view
def initialize(view)
@view = view
end
def mygroupsopenwos(user)
select("workorders.*").joins("left outer join empgroups ON empgroups.workgroup_id=workorders.workgroup_id").where("empgroups.employee_id = ?", user).where("wostatus_id NOT IN (?)", [231, 230, 9263, 9264, 232] )
end
def as_json(options = {})
{
sEcho: params[:sEcho].to_i,
iTotalRecords: workorders.mygroupsopenwos(current_user).count,
iTotalDisplayRecords: workorders.mygroupsopenwos(current_user).total_entries,,
aaData: data
}
end
private
def data
workorders.mygroupsopenwos(current_user).map do |workorder|
[
...
但是,我收到以下错误:
NoMethodError - undefined method `mygroupsopenwos' for #<ActiveRecord::Relation:0x007f9b046ccb08>:
如何定义mygroupsopenwos
以便我可以使用它?我应该把它放在控制器中吗?
