我有一个rails应用程序，在NFL周显示游戏。因此，如果用户导航到：url.com/week/1/，它将显示所有游戏。
格式为：/ week /：id
控制器如下所示：
def show
@week = Week.find(params[:id])
@user = User.first #place holder until current_user is implemented
@games = @week.games
end
当我去查看我得到的页面时：
ActiveRecord::RecordNotFound in WeekController#show
Couldn't find Week with 'id'=
Extracted source (around line #154):
152

154
155

157
record = s.execute([id], self, connection).first
unless record
raise RecordNotFound, "Couldn't find #{name} with '# {primary_key}'=#{id}"
end
record
rescue RangeError
ID是空白的，但我不明白为什么，因为它在参数中：
Request
Parameters:
{"id"=>"4"}
我可以使用rails控制台验证此记录/周应该存在，但是rails由于某种原因无法找到它...这工作正常并且当我添加一些验证时突然停止工作另一种模式，但我不知道它们是如何相关的。这是一个非常简单的查询。
有什么想法吗？
