Question

我无法将其保存到数据库中。当我将数据提交到数据库时，它只会显示name_of_bear和所有关系内容（type_of_fish），但不会显示type_of_bear

有人可以向我解释为什么它不起作用，也许可以给我一个如何做的例子。谢谢

控制器:(这有效）

public function submit(Request $request)
{
    $fishType= $request->input('type_of_fish');
    $Name = $request->input('Name');
    $bearType = $request->input('bearType');

    $bear = Bear::create(['Name' => $request->input('name_of_bear')]);
    $bear->fishs()->create(['type_of_fish' => json_encode($fishType)]);

    return ('thank you');

}

但如果我这样做：

控制器:(不工作）

public function submit(Request $request)
{
    $fishType= $request->input('type_of_fish');
    $Name = $request->input('Name');
    $bearType = $request->input('bearType');

    $bear = Bear::create(['Name' => $Name]);
    $bear = Bear::create(['bearType' => $bearType]); --> doesn't  work if add in this
    $bear->fishs()->create(['type_of_fish' => json_encode($fishType)]);

    return ('thank you');

}

或者这个：

控制器:(不工作）

public function submit(Request $request)
{
    $fishType= $request->input('type_of_fish');
    $Name = $request->input('Name');
    $bearType = $request->input('bearType');

    $bear = Bear::create(['Name' => $Name], ['bearType' => $bearType]); --> doesn't work
    $bear->fishs()->create(['type_of_fish' => json_encode($fishType)]);

    return ('thank you');

}

Answer 1

您可以像这样添加

$bear = Bear::create(['Name' => $Name , 'bearType' => $bearType]);

完整代码：

public function submit(Request $request)
{
    $fishType= $request->input('type_of_fish');
    $Name = $request->input('Name');
    $bearType = $request->input('bearType');

    $bear = Bear::create(['Name' => $Name , 'bearType' => $bearType]);
    return ('thank you');
} // removed extra }

你可以使用：

$bear = Bear::create(['Name' => $Name, 'bearType' => $bearType]);

Answer 3

您可以插入如下数据：

public function submit(Request $request)
{
    $data = array();
    $data['type_of_fish']= $request->type_of_fish;
    $data['Name'] = $request->Name;
    $data['bearType'] = $request->bearType;

    $bear = Bear::create($data);

    return ('thank you');

}

Answer 4

我会这样做，假设post数组键与列名匹配。

$bear = Bear::create($request->all()->except(['_token', 'type_of_fish']));

使用create function laravel将数据保存到数据库中
