当我在form_for标签中使用collection_select时，ActionController :: InvalidAuthenticityToken

Question

我是ruby on rails的新手。 我试图发送选择选项选择的数据，但在创建动作ActionController :: InvalidAuthenticityToken被引发，我无法弄清楚原因。 如果我从表单中删除collection_select行，则表单提交。

应用程序/视图/代码/ new.html.erb

<%= form_for @code, url: {action: "create"}, html: {class: "form-horizontal form-bordered"} do |f| %>

<div class="form-body">
<div class="form-group TextBoxContainer">
<label class="control-label col-md-2"> Tracking Code(s) </label>
<div class="col-md-6">
<%= f.text_field :code, name: "[code][]" , class: "form-control",placeholder: "Enter Tracking Code(s) for Analytics" %>
</div>
<div class="actions col-md-4 div_tag">
<button type="button" class="btn dark btn-outline add_another_code">
<i class="fa fa-plus"></i> Add Another Code</button>
</div>
</div>
</div>


<!-- <%= f.collection_select(:webpage_id,Webpage.all, :id, :title,{prompt: true})%>  -->






<%= f.button :submit, class: 'btn red btn-lg' %>
<% end %>

这是我的codes_controller.rb

应用程序/资产/控制器/ codes_controller.rb

class CodesController < ApplicationController



def new                 
@code = Code.new

end

def create

debugger

@code = Code.new
@code.webpage_id = params[:webpage_id]
params[:code].each  do |code|
@code.code << code

end

if @code.save

redirect_to '/'

else
render 'new'

end

end


def edit
@code = Code.find(params[:id])
end

def update 


   @code = Code.find(params[:id])


   if @code.update(code_params)

    redirect_to '/'
  else
    render 'edit'
  end

end







private


def code_params
params.require(:code).permit(:webpage_id,code:[])

end

end
