ruby-on-rails – 缺少param或值为空

我是Rails的新手.得到以下错误.我明白这个问题是什么,但不确定如何修复它？

错误 – 参数丢失或值为空：客户

def customer_params
      params.require(:customer).permit(
        :first_name,:last_name,:email,:password,:password_confirmation)
    end
   end

DetailsController.rb

class My::Account::DetailsController < MyController

 def show
   @customer = current_user
 end

 def update
   @customer = current_user
   @customer.update_attributes(customer_params)
   if @customer.errors.any?
     render :action => :show
   else
     redirect_to my_account_details_path,:notice => 'Account details updated'
   end
    end

   private

   def customer_params
      params.require(:customer).permit(
        :first_name,:password_confirmation)
    end
   end

视图

.account.container
.row
    = render :partial => '/my/account/sidebar'
    .section
        %h2 Your account details

        = simple_form_for @customer,:url => my_account_details_path,:method => :put,:html => { :class => 'form-horizontal'} do |form|
            .field
                = form.input :first_name

            .field
                = form.input :last_name

            .field
                = form.input :email,:as => :email

            %hr
            %h4 Leave password fields blank to keep the existing password
            %hr

            .field
                = form.input :password,:input_html => { :value => '' }
            .field
                = form.input :password_confirmation,:input_html => { :value => '' }

            .field-actions
                %button.btn.btn-primary{type: "submit"} Save

解决方法

这是因为它是作为用户而不是客户而来的.我认为是因为您使用的是current_user,它是用户而不是客户(从代码中猜测).将其更改为params.require(：user).permit(blah)
