Question

非常快我得到了这个错误：＆＃34;语法错误，意外的tIDENTIFIER，期待＆＃39;＆＃39;＆＃39;＆＃34;＆＃34;，当我试图使用这些代码在db中查找值时（我刚刚学习红宝石）。

  def load_leagues
    @men_leagues = League.where(kind: 'men').order('id ASC').find_all
    @men_active_leagues = League.where(active: true AND kind: 'men').order('id ASC').find_all
    @women_leagues = League.where(kind: 'women').order('id ASC').find_all
    @current_user = current_user
  end

我认为@men_active_leagues的行是给我带来麻烦的。

感谢您的一切！

Answer 1

ruby中没有AND运算符。

要在where语句中使用AND，您可以指定两个参数。

@men_active_leagues = League.where(active: true, kind: 'men').order('id ASC').find_all

或者您可以将其指定为字符串

@men_active_leagues = League.where("active = TRUE AND kind = 'men'").order('id ASC').find_all

Answer 2

以下解决，不言自明，散列组合错误：

def load_leagues
   @men_leagues = League.where(kind: 'men').order('id ASC').find_all
   @men_active_leagues = League.where({active: true, kind: 'men'}).order('id ASC').find_all
   @women_leagues = League.where(kind: 'women').order('id ASC').find_all
   @current_user = current_user
end

语法错误，意想不到的tIDENTIFIER，期待＆＃39;）＆＃39;
