Question

我试图在两个数据库表之间建立多态关系。

database1：SaleReport database2：ThreadConnection

数据库1上的SaleReport下的

数据库2上的ThreadConnection上的

public function relates(){
    return $this->morphMany(ThreadConnection::class, 'relation');
}

但是当我试图获得像

这样的关系时

public function relation(){
    return $this->morphTo();
}

我还尝试将数据库连接定义到ThreadConnection

$这 - ＆GT; setConnection（ 'DATABASE2'） - ＆GT; morphTo（）;

但这也不起作用！

任何建议都是适当的

Answer 1

如前所述，

阅读错误：

 protected $connection = 'database2';

含义Laravel正在寻找模型ThreadConnection的database1连接（如果model指的是另一个应该明确设置的连接，则database1应该是默认连接）

添加ThreadConnection：

/*search name is clinic name
clinicsearch is the arrayelement which has the list of clinic name list from the table*/
public SearchAndSelectClinicA(SearchName:string){
  this.ClinicSearch.sendKeys(SearchName);
  this.SearchIcon.click(); //click on the icon to get the clinic names
  this.SearchedClinic.count().then(function(count){
    //get the count of elements which are there in the Searchedclinic element array
    if(count>1){
      this.SearchedClinic.each(function(rows){ 
        /*Failed: Cannot read property 'SearchedClinic' of undefined 
          (Error gets displayed when it comes to above line.*/
        rows.getText().then(function(value){
          if(value.indexOf(SearchName)){
            //Click the element if the statement is satisfied
            rows.click();
          }
        });
      });
    }
  });
}

将解决问题。
