javascript - “字段列表”中的未知列 'created_at'

Question

这是我的customer_schema.js 文件:

up () {                                                                                                                                        
    this.create('customers', (table) => {                                                                                                        
      table.increments()                                                                                                                         
      table.string('name', 30)                                                                                                                   
    })                                                                                                                                           
  }

CustomerSeed.js:

class CustomerSeeder {                                                                                                                           
  async run () {                                                                                                                                 
    const customer = await Factory                                                                                                               
      .model('App/Models/Customer')                                                                                                          
      .create()                                                                                                                              
    console.log('customer: ')                                                                                                                    
  }                                                                                                                                              
}

Customer.js 模型是“空”

我运行迁移，一切正常，但无法运行种子:adonis seeds 抛出此错误消息:

code: 'ER_BAD_FIELD_ERROR',

为什么会发生这种情况？我什至没有在我的架构文件中声明 table.timestamps() 并且:

describe customers;

2 rows in set (0.01 sec)

Answer 1

编辑:

  static get createdAtColumn () {
    return null;
  }

  static get updatedAtColumn () {
    return null;
  }

将这两个函数添加到您的模型中，它应该可以工作:)
