Question

我试图更新我的Representation属性ivpn＆amp; idirect（来自csv文件，通过rake任务，但我只是打印在这里只是程序的内容）并得到TypeError：

# in Rails Console:
representation = Representation.where(id: 977)
# => Representation_id: 977, ivnp: false, idirect: false

rows = Hash.[:ivpn => "", :idirect => "x"] # originally rows are coming from csv-file

representation.update_attributes! ivpn: rows.any?{|r| r[:ivpn].present?}, idirect: rows.any? {|r| r[:idirect].present?}

TypeError: can't convert Symbol into Integer
        from (irb):42:in `[]'
        from (irb):42:in `block in irb_binding'
        from (irb):42:in `each'
        from (irb):42:in `any?'

我在这里失踪了什么？

Answer 1

试试这个：

representation.update_attributes! ivpn: rows.any?[{|r| r[:ivpn].present?}], idirect: rows.any? [{|r| r[:idirect].present?}]

ruby / rails：TypeError：无法将Symbol转换为Integer
