laravel使用findOrFail来验证其他记录不是id

Question

I have table contain id, customer_id,..etc so findOrFail will work only for id so want to check customer_id record not id. How can I check other record using findOrFail something like this

$post = Customer::findOrFail('customer_id',$request->customer_id)

Answer 1

Maybe you are looking for firstOrFail() , so you can do:

Customer::whereCustomerId($request->customer_id)->firstOrFail();

findOrFail() only works for the primary key id so you have to use firstOrFail .

Note that you could also write it as:

Customer::where('customer_id', $request->customer_id)->firstOrFail();

Answer 2

You can use any column of a table

Customer::where('<any column>', <column value>)->firstOrFail(); 

Laravel example

$model = App\Flight::findOrFail(1);

$model = App\Flight::where('legs', '>', 100)->firstOrFail();
