Laravel与将可变大小写更改为蛇形大小写 [英] Laravel "with" changes variable case to snake case

问题描述

在我的Laravel应用中，我有一个模型，该模型定义了如下关系:

In my Laravel app, I have A model that defines a relationship like:

public function vitalCategories()
{
    return $this->belongsToMany(
        'App\Models\Diagonals\VitalLabelCategory',
        'vitalLabelCategoryMap',
        'vitalLabelId',
        'vitalLabelCategoryId');
}

当我查询如下记录时，我希望该关系可以使用变量名称vitalCategories

When I query a record like below, I expect the relation to be available with the variable name vitalCategories

$vitalLabel = VitalLabel::where('label', 'confirmation')->with(['subscribers','vitalCategories','vitals'])->first();
return json_encode($vitalLabel);

但是，上面的查询生成的变量名称为'vital_categories'的关系如下:

However, the above query produces the relation with the variable name 'vital_categories' like this:

如何让laravel停止更改变量的大小写以使其与蛇形情况有关?

只是出于笑容，我也尝试过:

Just for grins, I also tried:

$vitalLabel = VitalLabel::where('label', 'confirmation')->with(['subscribers','vitalCategories','vitals'])->first();
$vitalLabel->load('vitalCategories');
$vitalLabel->vitalCategories = $vitalLabel->vitalCategories() ;
return json_encode($vitalLabel);

未能查看相关模型:

所以我尝试了:

$vitalLabel = VitalLabel::where('label', 'confirmation')->with(['subscribers','vitalCategories','vitals'])->first();
$vitalLabel->load('vitalCategories');
$vitalLabel->vitalCategories = $vitalLabel->vital_categories;
return json_encode($vitalLabel);

也没有看到相关模型:

推荐答案

当模型转换为数组(toArray())或json().

Laravel automatically converts the names of relationships from camelCase to snake_case when the model is converted to an array (toArray()) or json (toJson()).

因此，模型上的属性实际上是vitalCategories，但是当您将其转储为json时，它将打印为vital_categories.

So, the attribute on the model is actually vitalCategories, but when you dump it out as json, it will print as vital_categories.

如果要关闭此功能，可以将模型的$snakeAttributes属性设置为false.

If you would like to turn this off, you can set the $snakeAttributes property on your model to false.

public static $snakeAttributes = false;
