How can I use && in if in Ruby on Rails?

提问by Timothy T.

I tried the following && conditional for my if statement and I get a "bad range" error:

我为 if 语句尝试了以下 && 条件,但出现“错误范围”错误:

<% if (from_today(contact, call.days) == 0..7) && (show_status(contact, call) == 'no status') %>

Why and how can I fix it? The only other way I could do it was to have a second nested if statement and break it apart...not pretty :(

为什么以及如何修复它?我能做到的唯一另一种方法是使用第二个嵌套的 if 语句并将其分解...不漂亮:(

<% if (from_today(contact, call.days) == (0..7) && show_status(contact, call) == 'no status') %>

Try putting the 0..7in parentheses. The &&is not your problem here.

尝试将 放在0..7括号中。这&&不是你的问题。
