一次提交多次保存

Question

我需要一个包含1个单选按钮，1个提交按钮和每个列出项的复选框的表单。

提交后，表单应为每个检查项目保存单独的记录。每个保存的项目都应该包含单选按钮的值以及其他隐藏值。

表单呈现，但在提交时崩溃。该错误信息是：

undefined method `permit' for #<Array:0x007fb4b3b1a520> 

我的代码是：

 <%= form_tag(controller: "handoffs", action: "create", method: "post") %> 
      <%= radio_button_tag(:attend, "arrive") %> 
      <%= label(:handoff_arrive, "drop-off") %> 
      <%= radio_button_tag(:attend, "depart") %> 
      <%= label(:handoff_depart, "pick-up") %> 

      <% @parent.children.each do |child| %> 
       <%= check_box_tag "handoff[][check]" %> 
       <strong> 
       <%= child.fname %> 
       <%= child.mname %> 
       <%= child.lname %> 
       </strong><br> 

       <% group = Group.find(child.group_id) %> 

       <%= hidden_field_tag "handoff[][attend]" %> 
       <%= hidden_field_tag "handoff[][group_name]", :value => group.name %> 
       <%= hidden_field_tag "handoff[][child_id]", :value => child.id %> 
       <%= hidden_field_tag "handoff[][center_id]", :value => @center.id %> 
       <%= hidden_field_tag "handoff[][escort_fname]", :value => @parent.fname %> 
       <%= hidden_field_tag "handoff[][escort_lname]", :value => @parent.lname %> 
       <%= hidden_field_tag "handoff[][child_fname]", :value => child.fname %> 
       <%= hidden_field_tag "handoff[][child_mname]", :value => child.mname %> 
       <%= hidden_field_tag "handoff[][child_lname]", :value => child.lname %> 
      <% end %> 
      <%= button_to :submit, :class => 'f_submit' %> 
     <% end %> 

控制器操作：

def new 
    @handoff = Handoff.new 
    @parent = current_parent 
    @center = Center.find(@parent.center_id) 
    end 

    def create 
    params["handoff"].each do |handoff| 
     if params[:handoff["check"]] != "" 
     @handoff = Handoff.new(handoff_params) 
     @handoff.save 
     end 
    end 
    end 

    def handoff_params 

    params.require(:handoff).permit(:attend, :group_name, :child_id, :center_id, :escort_fname, :escort_lname, :child_fname, :child_mname, :child_lname) 
    end

我有类似的案件。首先，您需要创建包含您想要导出的所有值的数组，我使用helper来执行此操作。我会告诉你我的例子：

def get_table_of_keywords(keywords) 
    exact_keywords = [] 
    keyword_array.each do |key| 
     if !key.blank? 
     exact_keywords << {keyword: key, created_at: DateTime.now.in_time_zone, updated_at: DateTime.now.in_time_zone } 
     end 
    end 
    exact_keywords 
    end 

，并且您使用的创建：

@inserted_keywords = @campaign.keywords.create(get_table_of_keywords(params[:keyword][:keyword])) # add new keywords to the list
