如何在Laravel集合中编辑项目 [英] How to edit items in laravel collection

问题描述

我是laravel的新手，我运行查询并从数据库中获取行，我想在查看这些行之前对其进行编辑. 所以这是我的代码片段:

I am new in laravel, I run a query and get rows from database and I want to edit a column of this rows before get them in view. So here is my code piece :

$callPlans = CustomerCallPlan::whereNotNull('id');

foreach ($callPlans->get() as $callPlan) {
    dd($callPlan);
}

输出截图:

我需要将所有'x'字符替换为numbertemplate列的'-'.

I need to replace all the 'x' characters with '-' of numbertemplate column..

推荐答案

如果要始终对模型进行此转换，则只需将以下访问器方法添加到模型类中即可:

If you want to do this transformations always for your model, you can just add the following accessor method to the model class:

public function getNumbertemplateAttribute() {
  return str_replace('x', '-', $this->attributes['numbertemplate']);
}

现在，每次访问 $ customerCallPlan-> numbertemplate 时，您都将获得转换后的字符串.

Now everytime you access $customerCallPlan->numbertemplate you will get the converted string.

否则，在获取数据时只需转换列:

Otherwise just convert the column when you fetch the data:

$plans = $callPlans->get()->map(function($plan) {
  $plan->numbertemplate = str_replace('x', '-', $plan->numbertemplate);
  return $plan;
});
