Problem with adding external edit to the grid

[Miroslav]

Hello all,

For a few hours I tried to create CRUD functionality but the only thing that I couldn't do was the create. In the attached file is the code I use. When I open the console I see the following error: Uncaught ReferenceError: tech_type_id is not defined.
Thank for the help in advance.

Hello Miroslav,

The error you are getting is caused by the fact that there is no tech_type_id defined when the new item is created. Therefore, you should describe your model in the schema declaration:

schema: {
      //..
       model: {
           id: 'tech_type_id',
           fields: {
               tech_type_id: { nullable: true },
               tech_type: "tech_type"
           }
       }
   }

And then create the new item:

var model = ds.add();
model.set("tech_type", $('#add_tech_type').val());
ds.sync();
