I am new in laravel and I am trying to pass parameters from a function in controller to a function in model. I have done this :
我是 laravel 的新手，我试图将参数从控制器中的函数传递到模型中的函数。我已经这样做了：
My controller
我的控制器
class DashBoardController extends BaseController {
public function yesterdayOrderData(){
$from = date('Y-m-d H:i:s', strtotime('today -1 days'));
$to = str_replace("00:00:00", "23:59:59", $from);
$odata = Invoice::yesterdaysorderdetails($from, $to);
}
}
My Model :
我的型号：
class Invoice extends Eloquent{
protected $table = 'Inf_Invoice';
public function scopeyesterdaysorderdetails($from, $to){
echo $from."--".$to;
}
}
I am getting error message "Object of class Illuminate\\Database\\Eloquent\\Builder could not be converted to string"
我收到错误信息 "Object of class Illuminate\\Database\\Eloquent\\Builder could not be converted to string"
How can I pass parameters from my controller to model ??
如何将参数从我的控制器传递到模型？

Scope requires queryinstance to be 1st param (it's automatically passed to the function):
范围要求query实例是第一个参数（它会自动传递给函数）：
// you don't need to use camelCase, but it's soooo hard to read this otherwise..
public function scopeYesterdaysOrderDetails($query, $from, $to){
$query->whereBetween('created_at', [$from, $to]);
}
// usage:
$odata = Invoice::yesterdaysOrderDetails($from, $to)->get();
Just a note about the method name - it should follow one rule - first letter after the scopepart should be uppercase.
只是关于方法名称的注释 - 它应该遵循一个规则 -scope部分后面的第一个字母应该是大写的。

You should change your function name from scopeyesterdaysorderdetailsto yesterdaysorderdetails. It seems scopes are special functionsand they take only one parameter $querywhich is probably Eloquent Builder and that's why you get this error.
您应该将函数名称从 更改scopeyesterdaysorderdetails为yesterdaysorderdetails。似乎作用域是特殊函数，它们只接受一个参数$query，这可能是 Eloquent Builder，这就是您收到此错误的原因。
And in your situation you just want to display 2 dates separated with --so you don't need scope functions for that, just normal function that cannot begin with scopeI think
而在你的情况下，你只是想显示2个日期与分开的--，所以你不需要示波器功能为，只是正常的功能，可以不首先scope我想
