Question

customers_controller.rb

  def export
@customers =Customer.all

flash[:success] = "Script ran successfully"
end

当错误消息说出语法错误，意外的keyword_do，期望keyword_end flash [：success] =＆＃34;脚本成功运行＆＃34;做|格式| ^。我试图使用flash成功方法从我的数据库导出cvs文件。我看看rails cast，但它无法解决这个问题 index.html.erb

 <p><%= button_to 'export Import', scripts_export_data_path %></p>

检查语法并阅读错误（正如Zabba在评论中提到的那样）。你会想要类似的东西：

var Radium = require('radium');
var React = require('react');

@Radium
class Grabby extends React.Component {
  render() {
    return (
      <div style={style}>
        {this.props.children}
      </div>
    );
  }
}

var style = {
  cursor: "grab" // this will get autoprefixed for you!
};

请注意FrameLayout.LayoutParams params = new FrameLayout.LayoutParams(FrameLayout.LayoutParams.MATCH_PARENT, FrameLayout.LayoutParams.MATCH_PARENT); params.gravity = Gravity.BOTTOM; titleTextView.setLayoutParams(params); n1.addView(titleTextView);块respond_to do |format| format.csv { render text: @customers.to_csv } flash[:success] = "Script ran successfully" end是如何存在的。请务必阅读您的错误消息，因为它们非常有用。

我使用方法调用flash成功导出CSV但我收到错误
