使用 Eloquent 插入和更新基于多行的外键的最佳方法是什么？

Question

I have a table named 'answers' which will store customer answer about questionnaire. The table looks like this

answers
+-----------------+
|id (PK)          |
|customer_id (FK) |
|question_id (FK) |
|value            |
|_________________|

my request would be like this

{
    "customer_id":1,
    "answer": {
        "1":"My Name", //"1" is question_id , "My Name" is value
        "2":"My Phone Number" //"2" is question_id, "My Phone Number" is value
    }
}

What i'm trying to achieve is doing a single query or single action on Eloquent instead of foreach the answer one by one to check if the question_id and customer_id already exists it will update otherwise it will insert the answer to table 'answers'.

By doing foreach/looping one by one per answer data, it shouldn't be a hard problem. However if i already got 3000++ rows in 'answers' table then it would be a big problem.

What is the best approach to do this? Maybe is there any third-party library that i can use to do Mass Insert/Updates multiple rows based on foreign key check?

You can do this by laravel's UpdateORCreate Method which do the exact thing that you want.

In General the statement is like below:

$model=Model::UpdateOrCreate(["condtion1"=>"value1",...],["field1"=>"value1",...]);

In your case it'll be something like below:

$answer=Answer::UpdateOrCreate(["customer_id"=>$customer_id,"question_id"=>$question_id],["value"=>$value]);
