fact data error in cubes server 0.10 about cubesviewer HOT 1 CLOSED

Thanks for the detailed error report. Seems that what you see is a Cubes error message (not CubesViewer).

It seems that there is no id column in the OrderDetails fact table. In order for Cubes to return facts, each fact needs a key. By default it will use the id column, but you can specify which column is your key using the key attribute of the cube (see documentation: https://pythonhosted.org/cubes/model.html#cubes ).

I think it will work once you define a valid key. As stated in Cubes doc, "If not specified, backends might either refuse to generate facts or might use some default column name such as id.".
