Question

按照Railscast 396剧集中列出的步骤，我已成功导入CSV文件。但是，现在我尝试导入嵌套的csv。我看过人们试图导入父数据和子数据的其他帖子，但在这种情况下，我试图只在econ_report节目视图中导入子数据。

例如，我有econ_results，我试图导入嵌套在econ_report下。 rake文件显示以下链接。

import_econ_report_econ_results

当我尝试加载econ_report的显示页面时，我收到以下错误

No route matches {:action=>"import", :controller=>"econ_results", :id=>"1"} missing required keys: [:econ_report_id]

我在econ_result.rd文件中有以下代码：

def self.to_csv
CSV.generate do |csv|
  csv << column_names
  all.each do |sub|
    csv << sub.attributes.values_at(*column_names)
  end
end
end

 def self.import(file)
CSV.foreach(file.path,headers: true) do |row|
  EconResult.create! row.to_hash
end
end

最后，在econ_results_controller中，我有以下代码：

before_action :set_econ_report
def set_econ_report
@econ_report = EconReport.find(params[:econ_report_id])
end

def import
EconResult.import(params[:file])
end

def create
@econ_result = @econ_report.econ_results.create(econ_result_params)
redirect_to @econ_report
end

@econ_report的指定是否导致控制器发生冲突？

Answer 1

你需要告诉rails你传递的记录是<%= link_to import_econ_report_econ_results_path(econ_report_id: @econ_report) %>参数。默认情况下，路由助手将使用id参数的传递记录。

我会写一个帮助方法，因为名字太长了。
