在 Illuminate\Database\QueryException 处获取未找到列错误？

Question

我正在 Laravel 应用程序中工作，并将users表格与posts表格逐user_id列相关联。我已经user_id在表中有列了posts。但是当我运行php artisan db:seed命令时，出现错误：

`SQLSTATE[42S22]：未找到列：1054“字段列表”中的未知列“user_id”

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 之后有一个空格。或者你需要找到你在哪里使用了user_id后面的空格。
