Laravel 5.5：将查询构建器转换为 eloquent

Question

Is there a way to transform this query builder to eloquent?

$transactions = DB::table('transactions')
    ->join('accounts', 'transactions.account_id', '=', 'accounts.id')
    ->select('transactions.*', 'accounts.name as account_name')
    ->paginate(5);

I tried it with One To Many . But it need the find() function so it give me one account's transactions but I need to select all transactions with accounts.name

Answer 1

In comments, you've said you have one to many relationship defined (I assume it's Accounts has many Transactions) and you need to get all transactions with account name, so do this:

Transaction::with('account')->paginate(5);

Where account is relationship:

public function account()
{
    return $this->belongsTo(Account::class);
}

Then you'll be able to display the data like this:

@foreach ($transactions as $transaction)
    {{ $transaction->id }}
    {{ $transaction->account->name }}
@endforeach

You will need to use models to do that.

1. Transaction model and Account model.

2. Define their relationships

3. Create a method in the transaction model to retrieve the related account names.

   function accoutNames() { //blablabla }

4. Do the query in controller, something like that:

   Transaction->accountNames();
