thinkphp5.1模型的关联不会自动插入外键的值，还需要自己添加所以直接用拓展表操作就行好了

Posted 2021-05-15 代码当酒喝

        $art = ArticleModel::create([
            'title' => $params['title'],
            'user_id' => session('index_info')->id,
            'type' => $params['type'],
            'publish_type' => $params['publish_type'],
        ]);
        
        
        $art->article_ext()->create([
            'article_id' => $art->id,
            'content' => $params['content'],
        ]);

这样用

        $res = ArticleModel::create([
            'title' => $params['title'],
            'user_id' => session('index_info')->id,
            'type' => $params['type'],
            'publish_type' => $params['publish_type'],
        ]);
        //拓展表
        ArticleExt::create(
            [
                'article_id' => $res->id,
                'content' => $params['content'],
            ]
        );
