public function company(){
return $this->hasOne('App\Company');
}

}
}
I'm trying to get a list of all the clients of a company and this is what I tried to do:

$clients = Company::where('guid',$guid);
This returns the Builder class, so when you then add ->clients()it will give you error because the builder class does not have the clients method, your model does.
这将返回 Builder 类，因此当您添加->clients()它时会出现错误，因为 builder 类没有 clients 方法，而您的模型有。
The correct code would be..
正确的代码是..
$clients = Company::with('clients')->where('guid',$guid)->get();
PS. Don't use ->all()unless it's something like $companies = Company::all()
附注。->all()除非它是类似的东西，否则不要使用$companies = Company::all()
回答by Vinicius Luiz
Your relationship defined at the model must be called like this:
您在模型中定义的关系必须像这样调用：
$clients = Company::where('guid',$guid)->clients;
It will query all clients at your company, don't use the method all() to do this. And on your Client model do the same to search by the company.
它将查询您公司的所有客户，不要使用 all() 方法来执行此操作。并在您的客户模型上执行相同的操作以按公司进行搜索。
$company = Client::where('id', 1)->company;
