If you want to do this transformations always for your model, you can just add the following accessor method to the model class:
如果您想始终为您的模型执行此转换，您只需将以下访问器方法添加到模型类：
public function getNumbertemplateAttribute() {
return str_replace('x', '-', $this->attributes['numbertemplate']);
}
Now everytime you access $customerCallPlan->numbertemplateyou will get the converted string.
现在每次访问$customerCallPlan->numbertemplate 时，您都会得到转换后的字符串。
Otherwise just convert the column when you fetch the data:
否则，只需在获取数据时转换列：
$plans = $callPlans->get()->map(function($plan) {
$plan->numbertemplate = str_replace('x', '-', $plan->numbertemplate);
return $plan;
});

}

$callPlan->update(["numbertemplate"=>str_replace("x", "-", $callPlan->numbertemplate]);
}
