Question

我一直在跟踪关于通过复选框更新的railscast，虽然我觉得我已经实现了逻辑并且页面显示我无法获得逻辑以表现它应该。我想知道是否有人可以提供任何建议，因为我觉得问题的一部分可能是我在haml中的实现。当我说我不能让逻辑工作时，我的意思是提交按钮不会更新任何东西！

查看：

    %h1 Diagnostics
-form_tag complete_admin_diagnostics_path, :method => :put 
/ - for diagnostic in @diagnostics do

%table
  %tr
    %th
    %th User
    %th Message
    %th Device
    %th RELS-Mobile Version
    %th Submitted
    %th Archive
  - @diagnostics.each do |diagnostic| 
    %tr
      %td
        %strong= link_to 'show', admin_diagnostic_path(diagnostic)
      %td
        - if diagnostic.user
          = link_to diagnostic.user.email, [:admin, diagnostic.user]
        - else
          unknown
      %td
        = diagnostic.data["message"]
      %td
        %pre= JSON.pretty_generate(diagnostic.data["device"])
      %td
        = diagnostic.data["appVersion"]
      %td
        = diagnostic.updated_at
      %td
        = check_box_tag "diagnostic_ids[]", diagnostic.id
        / = diagnostic.name


  = submit_tag "Mark as complete"
= paginate @diagnostics

控制器

class Admin::DiagnosticsController < Admin::BaseController
  before_filter :diagnostic, :except => [:index, :complete]

  def index
    @diagnostics = DiagnosticInfo.all.order_by(:created_at.desc).page(params[:page]).per(50)
    # @diagnostics = DiagnosticInfo.where(archived: false).entries
  end


  def show
    respond_to do |format|
      format.html
      format.json { render json: @diagnostic }
    end
  end

  def update
    if @diagnostic.update_attributes(params[:diagnostic_info])
      redirect_to admin_diagnostic_path, notice: 'Successfully updated.'
    else
      render action: "edit"
    end
  end

  def edit
  end

  def destroy
    diagnostic.destroy
    redirect_to admin_diagnostics_path
  end

  def complete
    @diagnostic.update_all(["completed_at=?", Time.now], :id => params[:diagnostics_ids]) 
  end


private

  def diagnostic
    @diagnostic = DiagnosticInfo.find(params[:id])
  end
end

我认为你需要打印出你的表格标签，否则，正如你所描述的那样，没有发送任何内容：

= form_tag complete_admin_diagnostics_path, :method => :put

希望有所帮助。

通过rails和haml中的复选框进行更新
