Question

Hello,
I have an issue with saving data in my database, I can’t find the problem. The QueryBuilder for And-, Or- and OrAnd-Select are the same. . I wrote the QueryBuilder in code consecutively for And-select , Or-select and OrAnd-Select in this exact order. Saving data in NosqlDb works only for And- and OR-select .

But OrAnd-select fails to save. In the picture shown, you can see that the data in database doesn’t save. Data in database User_DataDb saves successfully. I would appreciate any help!

Thank you in advance.

enter image description here

I get this error:

でセーブデータとの問題は、私がここにあなたの問題はあなたがオブジェクトを使用すると、同時に保存しているWICH変更しようとしていること、だと思います。 同じオブジェクトを一度に1回のみ変更して保存するようにしてください。また

、あなたはすでにロードされたオブジェクトをロードしないでください。

var promiseOr = queryBuilderOr.or(techniques, functional, nonFunctional) 
    .resultList() 
    .then((nosqlDbOr) => { 
     console.log(nosqlDbOr); 
     this.nosqlDbsOr = nosqlDbOr; 
     console.log("this.nosqlDbsOr ", this.nosqlDbsOr); 

     this.nosqlDbsOr.forEach((or) => { 
      //you do not need a db.NoSqlDB.find() here the object is already loaded 

      if (and.users_or === null) { 
       and.users_or = new Set(); 
      } 
      or.users_or.add(db.User.me); 

      //You are selecting the same object in the different queries multiple times. 
      //Therfore do not update the objects in each of the resultList() callbacks 
      return or.update(); 
     }); 
    });
