在 Illuminate\Database\QueryException 找不到列错误？

Question

我在 Laravel 应用程序中工作，并通过 user_id 列将 users table 与 posts table 相关联。我已经在 posts table 中有 user_id 列。但是当我运行 php artisan db:seed 命令时，我得到一个错误：

`SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_id ' in 'field list'

出现以下错误：

   Illuminate\Database\QueryException 

  SQLSTATE[42S22]: Column not found: 1054 Unknown column 'user_id ' in 'field list' (SQL: insert into `posts` (`user_id `, `title`, `post_image`, `content`, `user_id`, `updated_at`, `created_at`) values (11, Perferendis dolorem eum ex nesciunt., https://lorempixel.com/900/300/?54025, Unde voluptatibus praesentium unde et illum qui quo.

我认为在用户模型的关系函数中 user_id 之后有一个 space。或者你需要找到在user_id之后你在哪里使用space。
