Question

我有一个User和Reviewer表。

审核人跟踪user_id和reviewer_id

现在我的协会设置如下：

current_user.my_reviewer.first_name

我尝试设置的是用户可以拥有一个评论者，但可以查看很多评论者。

现在我试图做到这一点，以便我可以做到

  has_one :my_reviewer, through: :reviewer, source: :user

f.ex并获取当前用户的评论者的名字。但目前

Could not find the source association(s) :reviewer in model Reviewer. Try 'has_many :my_reviewer, :through => :reviewer, :source => <name>'. Is it one of user or reviewer_user?

只是去找自己。我认为这与来源有关。如果我尝试将其更改为：reviewer我收到此错误：

PG::UndefinedColumn: ERROR:  column reviewers.reviewer_user_id does not exist
LINE 1: ... "users" INNER JOIN "reviewers" ON "users"."id" = "reviewers...
                                                             ^
: SELECT  "users".* FROM "users" INNER JOIN "reviewers" ON "users"."id" = "reviewers"."reviewer_user_id" WHERE "reviewers"."user_id" = $1 LIMIT 1

如果我将其更改为reviewer_user

我收到此错误：

$rollingCurl = new \RollingCurl\RollingCurl();
$rollingCurl
    ->get('https://www.google.com')
    ->get('http://www.msn.com')
    ->setCallback(function(\RollingCurl\Request $request, \RollingCurl\RollingCurl $rollingCurl) {
        // parsing html with regex is evil (http://bit.ly/3x9sQX), but this is just a demo
        if (preg_match("#<title>(.*)</title>#i", $request->getResponseText(), $out)) {
            $title = $out[1];
        }
        else {
            $title = '[No Title Tag Found]';
        }
        echo "Fetch complete for (" . $request->getUrl() . ") $title " . PHP_EOL;
    })
    ->setSimultaneousLimit(3)
    ->execute();

审稿人是用户，对吧？那么为什么不放弃审阅者表并执行此操作：

# user

has_many :reviewees, class_name: "User", foreign_key: "my_reviewer_id"
belongs_to :my_reviewer, class_name: "User"

为自我引用的has_one设置关联
