rails 报告中 ruby 中的分页错误

Question

我最近开始学习 ruby-on-rails，现在我已经到了可以创建一些东西但仍然不太熟悉语法的地步。在报告视图中，当我分页到第 2 页时出现错误。

但在 yesterday.Today 中更正了分页我使用 params.dig 方法编辑了一些复选框来保存复选框 values.those 值也需要在第二个 page.What 中显示我的控制器有问题

这是我的看法

 %br
          .row
            .col-md-3
              = check_box_tag "search_customer_supplier[accounts_dealer_types.dealer_code][]","CUS", params.dig('search_customer_supplier', 'accounts_dealer_types.dealer_code') == "CUS"
              = label_tag "Organizational Customer"
            .col-md-3
              = check_box_tag "search_customer_supplier[accounts_dealer_types.dealer_code][]", "SUP", params.dig('search_customer_supplier', 'accounts_dealer_types.dealer_code') == "SUP"
              = label_tag "Organzational Supplier"
            .col-md-3
              = check_box_tag "search_customer_supplier[accounts_dealer_types.dealer_code][]", "INDCUS", params.dig('search_customer_supplier', 'accounts_dealer_types.dealer_code') == "INDCUS"
              = label_tag "Individual Customer"
            .col-md-3
              = check_box_tag "search_customer_supplier[accounts_dealer_types.dealer_code][]", "INDSUP", params.dig('search_customer_supplier', 'accounts_dealer_types.dealer_code') == "INDSUP"
              = label_tag "Individual Supplier"

这是我的控制器

 def customer_supplier_report
    Organization
    Address
    ContactNumber
    refined_query = ""
    if params[:search].present? or params[:excel_report].present?

      search_customer_supplier = params[:search_customer_supplier]

      if params[:organization_children].present? and search_customer_supplier["id"].present?
        organization_id = search_customer_supplier["id"]
        organization = Organization.find(organization_id)
        anchestor_ids = organization.anchestors.map{|o| o[:member].id }
        search_customer_supplier["id"] = "(#{anchestor_ids.join(' OR ')})" if anchestor_ids.any?
      end

      params[:search_customer_supplier]['accounts_dealer_types.dealer_code'] = params[:search_customer_supplier]['accounts_dealer_types.dealer_code'].join(" OR ") if params[:search_customer_supplier]['accounts_dealer_types.dealer_code'].present?

      # puts params[:search_customer_supplier]['accounts_dealer_types.dealer_code']

      customer_report = params[:search_customer_supplier].map { |k, v| "#{k}:#{v}" if v.present? }.compact
    else
      customer_report = ["accounts_dealer_types.dealer_code:(CUS OR SUP OR INDCUS OR INDSUP)"]
    end

在我的浏览器中显示 controller.Those 中的错误行在哪里，

params[:search_customer_supplier]['accounts_dealer_types.dealer_code'] = params[:search_customer_supplier]['accounts_dealer_types.dealer_code'].join(" OR ") if params[:search_customer_supplier]['accounts_dealer_types.dealer_code'].present?

这是我得到的输出错误

ReportsController 中没有方法错误#customer_supplier_report

"CUS":String 的未定义方法 `join' 您是说吗？ JSON

Answer 1

您收到此错误是因为 join() 是 Array class 的方法。但是你的参数值是字符串类型的

即

[1,2,3].join(' OR ') #=> "1 OR 2 OR 3"

但是

"aasd".join('OR') #=> will throw exception which you are getting.

检查你的参数值是否是一个正确的数组

Answer 2

然后就出现了这个错误输出
