Php SQLSTATE[42S22]中的Laravel应用程序错误500:未找到列：1054未知列

我在xampp和php 7中有一个laravel应用程序，当我想要登录时，我得到一个错误500，如果我检查存储文件夹中的错误日志，我看到它是以下错误：

[2021-04-16 23:36:32] live.ERROR: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'username' in 'where clause' (SQL: select * from `users` where `username` = admin and `users`.`deleted_at` is null limit 1)
{"exception":"[object] (Illuminate\\Database\\QueryException(code: 42S22): SQLSTATE[42S22]: Column not found: 1054 Unknown column 'username' in 'where clause' (SQL: select * from `users` where `username` = admin and `users`.`deleted_at` is null limit 1) at 
C:\\xampp\\htdocs\\p2\\vendor\\laravel\\framework\\src\\Illuminate\\Database\\Connection.php:664, PDOException(code: 42S22): SQLSTATE[42S22]: Column not found: 1054 Unknown column 'username' in 'where clause' at C:\\xampp\\htdocs\\p2\\vendor\\laravel\\framework\\src\\Illuminate\\Database\\Connection.php:326)

这是我第一次见到whit laravel，我不知道如何解决这个问题，第326行和第664行的代码是下一个：

326

只是捕捉到了错误，也许是有用的

我从一家让我实习的公司收到了这份申请，但他们没有给我更多的帮助或指导，他们只是想让它发挥作用。

我很感激任何能帮助我解决这个问题的评论。

这意味着

用户名

不是

用户

表中的一列。你把这个错误理解成不同的意思了吗？我只想知道为什么？如果phpmyadmin中的数据库没有给我任何错误。证明它，将

show create table users

编辑到您的问题中。

public function select($query, $bindings = [], $useReadPdo = true)
{
    return $this->run($query, $bindings, function ($query, $bindings) use ($useReadPdo) {
        if ($this->pretending()) {
            return [];
        }

        // For select statements, we'll simply execute the query and return an array
        // of the database result set. Each element in the array will be a single
        // row from the database table, and will either be an array or objects.
        $statement = $this->prepared($this->getPdoForSelect($useReadPdo)
                          ->prepare($query));

        $this->bindValues($statement, $this->prepareBindings($bindings));

        $statement->execute();

        return $statement->fetchAll();
    });
}

protected function runQueryCallback($query, $bindings, Closure $callback)
{
   
    try {
        $result = $callback($query, $bindings);
    }

    // If an exception occurs when attempting to run a query, we'll format the error
    // message to include the bindings with SQL, which will make this exception a
    // lot more helpful to the developer instead of just the database's errors.
    catch (Exception $e) {
        throw new QueryException(
            $query, $this->prepareBindings($bindings), $e
        );
    }
