文本框是只读的 [英] Textboxes are read-only

问题描述

我有桌子:

• 产品
• ProductVariant
• 产品详细信息
  

• Product
• ProductVariant
• ProductDetails
  

ProductDetail包含价格，数量，sku，条形码等

ProductDetail has price, quantity, sku, barcode, etc

ProductDetails与Product和ProductVariant的关系为零或一对一(这种方式，我不需要重复的ProductDetails表)，因此ProductDetail最终具有Product或ProductVariant

ProductDetails has a zero or one TO one relationship with Product and with ProductVariant (This way I don't need a duplicate ProductDetails table) so a ProductDetail ends up having either a Product or a ProductVariant

在AddEditProduct屏幕上，我有以下代码来创建唯一的ProductDetail:

On the AddEditProduct screen, I have this code to create the unique ProductDetail:

myapp.AddEditProduct.created = function (screen) {
    // Create ProductDetail if it doesn't exist (new entity)
    var entity = screen.Product;
    entity.ProductDetail == null && (entity.ProductDetail = new myapp.ProductDetail);
};

最后一行是Guard Operator(与Guard运算符相同):if(detail == null)detail = new myapp.detail;)

The last line is a Guard Operator (same thing as: if (detail == null) detail = new myapp.detail;)

创建产品时，我可以填写Product.ProductDetail的字段，但是保存后，当我回去对其进行编辑时，这些字段是只读的.我已经调试了几个小时，无法弄清楚发生了什么，请帮忙！

When the product is created, I can fill in the fields of Product.ProductDetail but after I save, the fields are read-only when I go back in to edit them. I have been debugging this for hours and can't figure out what is going on, please help!

推荐答案

嗨.您尝试创建一个已经存在的新productdetail时，改用if语句，但您必须检查是否首先加载了productdetail创建的产品可能会触发得太早，然后is语句可能无法工作Sven

Hi. You are trying to create a new productdetail when it already exist Use a if statement instead but you have to check that productdetail i loaded first The created may fire too soon and then the is statement may not work Sven
