如何从table1中获取所有内容并通过laravel eloquent在单个查询中附加table2中的行数

Question

I'm using Laravel 5.8, and I have 2 tables in a (one-to-many) relationship as below:

Contacts DB

• id
• name
• number

Send DB

• id
• user_id
• text
• to
• time

what I want to achieve is a list of all (Contacts) along with how many (send) they've made that related to that (contact) by matching Contacts.id with Send.user_id,

here is the result of the query that I'm looking for:

Query result:

• id
• name
• number
• count of Sends

Thank you :)

Answer 1

You need to setup your model relationship

Add the following to your Contact Model:

public function sends()
{
    return $this->hasMany('App\Send', 'user_id'); //Assuming Send Model is directly in app folder
}

Then simply get your information:

$contact = Contact::withCount('sends')->get();

Answer 2

Worked like charm! I did tweak it to make it return a signal (contact)

Contact::where('id', $id)->withCount('sends')->get();

here is another way as ( Jonathan K ) suggested

Contact::where('id', $id)->withCount('sends')->first();

Thanks, Jonathan K
