Model ID in template

[Daniel]

Hi everyone,

I am facing a very interesting problem. I want to create a simple Todo app with DataSource and templating engine. ( I dont want to using Grid yet. )
The ID of my model is TODOID (I am using oracle db with open access.) I want to use this id field in the template. It works properly until I want to add a new Todo Item. For example:

$("#add-button").click(function () {
        dataSource.add({
            "TITLE": "asd",
            "PRIORITY": 3,
            "DEADLINE": "2013-02-02",
            "DONE": false
        });

        dataSource.sync();
    });

In that case, I get an error: "ReferenceError: TODOID is not defined". But if I include the TODOID field as well (e.g "TODOID": 100) then my create method is not being called. It is called only when I dont include the id field in new todo item AND I am not using that field in the template. But I have to use the TODOID field in the template to able to modify or delete and select an item.

So, how can i add a new todo item to the datasource without the reference error but also being able to select a single item in the UI?
Or I am doing it the wrong way and I have to use Grid?

Thank you for your answers,
Daniel

Hello,

This error happens probably because you are using the TODOID field somewhere and it isn't defined for a new item (inserted via the add method). The workaround is simple - add a defaultValue setting for that field in your data source declaration:

schema: {
    model: {
         id: "TODOID",
         fields: {
             "TODOID": { defaultValue: 0 },
              /* rest of configuration */
         }
    }
}
