我试图使用adonisjs将值插入到xampp mysql服务器中,但出现以下错误:
插入 posts ( body , created_at , title , updated_at )值(默认值,'2018-06-28 15:06:02','post 4','this is post 4','2018-06-28 15:06:02')-er\u wrong \u value \u count \u on \u row:列计数与第1行的值计数不匹配
这个错误告诉我的是,对于一个由4个值组成的表,我提供了5个值。事实上,“posts”表包含5个值,分别是:
id,标题,正文,创建时间,更新时间
我可以手动输入id,title,body的值,使用phpmyadmin,表将被更新,我的应用程序将反映更改。
我能追踪到的唯一问题似乎是postcontroller.js文件中的increments()方法。它的工作做得不对吗?
我怎样才能搞清楚这里发生了什么?
迁移文件posts\u schema.js:

'use strict'

const Schema = use('Schema')

class PostsSchema extends Schema {
  up () {
    this.create('posts', (table) => {
      table.increments()
      table.string('title')
      table.string('body')
      table.timestamps()
    })
  }

  down () {
    this.drop('posts')
  }
}

module.exports = PostsSchema

控制器postscontroller.js:

'use strict'

// Bring in model

const Post = use('App/Models/Post')

class PostController {
    async index({ view }){
      //  const posts = [
        //    {title:'Post One', body:'This is post one'},
          //  {title:'Post Two', body:'This is post one'},
           // {title:'Post Three', body:'This is post one'}
       // ]
        const posts = await Post.all();

        return view.render('posts.index', { 
            title: 'Latest Posts',
            posts: posts.toJSON()
        })
    }

    async details({ params, view}) {
        const post = await Post.find(params.id)

        return view.render('posts.details', {
            post: post
        })

    }

    async add({ view }) {
        return view.render('posts.add')
    }

    async store({ request, response, session }) {
        const post = new Post();

        post.title = request.input('title')
        post.body = request.input('body')

        await post.save()

        session.flash({ notification: 'Posted Success'})

        return response.redirect('/posts')
    }
}

module.exports = PostController

视图add.edge:

@layout('main')

@section('content')
    <a href="/posts">Go Back</a>
    <hr>
    <h1>Add Post</h1>
    <form action="/posts" method="POST">
        {{ csrfField() }} 
        <div class="form-group">
            <label>Title</label>
            <input type="text" name="title" class="form-control" placeholder="Title">
        </div>
        <div class="form-group">
            <label>Body</label>
            <textarea name="title" class="form-control" placeholder="Body"></textarea>
        </div>
        <button class="btn btn-primary" type="submit">Submit</button>
    </form>

@endsection

路由文件routes.js:

'use strict'

const Route = use('Route')

Route.on('/').render('home')

Route.get('/posts', 'PostController.index')

Route.get('/posts/add', 'PostController.add')

Route.get('/posts/:id', 'PostController.details')

Route.post('/posts', 'PostController.store')

我在配置xampp方面做得很少。我对config.inc.php的更改很简单:

$cfg['Servers'][$i]['controluser'] = 'root';
$cfg['Servers'][$i]['controlpass'] = '123456';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = 'root';
$cfg['Servers'][$i]['password'] = '12345';
/* Server parameters */
$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['compress'] = false;
$cfg['Servers'][$i]['AllowNoPassword'] = true;

从开始使用adonisjs开始,我们一直在学习这段代码和教程https://www.youtube.com/watch?v=saxhwbumtu4

如果这是您当前的插入:

insert into posts (body, created_at, title, updated_at) values (DEFAULT, '2018-06-28 15:06:02', 'post 4', 'this is post 4', '2018-06-28 15:06:02')

应该是:

insert into posts (body, created_at, title, updated_at) values ('this is post 4', '2018-06-28 15:06:02', 'post 4', '2018-06-28 15:06:02')

<textarea name="title" class="form-control" placeholder="Body"></textarea>

看起来像是 name 属性应为 body 而不是 title .
