Question

我正在使用API我有一个资源控制器来CRUD驱动程序，在我的更新功能中我收到此错误

for node in tree.findall('.//name'):
    mylist = list(node.text)
    print mylist

#output-- 
['M','e','d', 'i','a','n',' ','C','o','n','d','o',' ','V','a','l','u', 'e']
['M','e','d','i','a','n',' ','H','o','m','e',' ','V','a','l','u','e']
['H', 'o', 'm', 'e', ' ', 'T', 'y', 'p', 'e']

我在我的更新方法中def joinlists(lists): results = [] for list1 in lists: results.append(''.join(lists)) return results print joinlists(makelist)获得了所有JSON响应

 mylist2 = ['Median Condo Value', 'Median Home Value, 'Home Type']

但是QueryException in Connection.php line 770: SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'registration_center' cannot be null (SQL: update `drivers` set `registration_center` = , `registration_date` = 04-02-2017, `sponsor_name` = , `event_name` = , `registration_id` = 040217001, `profile_photo` = , `first_name` = , `last_name` = ,`updated_at` = 2017-02-04 04:54:54 where `id` = 3)我得到了dd($request);

我的方法

Request {#40
  #json: ParameterBag {#32
    #parameters: array:1 [
      "data" => array:61 [
        "id" => 3
        "agent_id" => "201705"
        "registration_center" => "dfgsdfgdfgdsdfgdf"
        "registration_date" => "03-02-2017"
        "sponsor_name" => "Sponser Name"
        "event_name" => "RC"
        "registration_id" => "FRTGHY030217001"
        "profile_photo" => ""","
        "first_name" => "Walter"
        "last_name" => "White"
        "created_at" => "2017-01-24 10:08:42"
        "updated_at" => "2017-02-03 11:33:52"
        "deleted_at" => null
      ]
    ]
  }

我的路线是

dd($request->registration_center);

期待急需的帮助

谢谢

Answer 1

从Laravel请求访问POSTed数据的一般方法是使用input方法。

$field = $request->input('field');

查看您的示例，似乎Request对象中有一个data字段，它是一个关联数组，registration_center就在其中。如果我做对了，那么在你的情况下，你会使用：

$update_driver->registration_center = $request->input('data')['registration_center'];

// or, using Laravel's "dot"-syntax
$update_driver->registration_center = $request->input('data.registration_center');

访问数据。对于您尝试检索的所有其他值也是如此。

Answer 2

由于它是一个数组，您需要使用以下命令访问它：

$request['data']['registration_center'];

Laravel 5.3更新方法不起作用
