问题描述
我已阅读文档并试图了解如何使用scipy.optimize.minimize(),但我做不到。
[
'label' => "Select Country",'name' => 'company_country','type' => 'select2_from_ajax','entity' =>'country',//method
'attribute' => 'name',//showing to user
'model' => "App\Models\Country",//foreign key
'data_source' => url('getCountry'),'placeholder' => 'Select country','minimum_input_length' => 3,'wrapperAttributes'=>['class'=>'form-group col-md-8'],] ```
In my controller i have this method for country
```
public function getCountry($id)
{
return Country::find($id);
} ```
What should go in Model and in the routes for that?
if someone provides a demo for the country,state and city,It is appreciatable.
输出:“ ValueError:用户提供的目标函数必须返回标量值。” 或类似的东西
解决方法
我已经解决了:x0应该是数字或(1,)数组
