Using db.table.format (i.e. format attr outside of table definition)

[Vlad]

Using the following

db.table.format = lambda row: 'test'

before SQLFORM.grid creation doesn't seem to work.

What's the proper way to set record representation outside of table definition?

[Vlad]

Please help! Any way to use this format property outside of a table definition?

[Val K]

Try db.table._format=...

Show your code, please

Oh, I see, here is what's happening: 

I now have the following code: 

   db.product._format = lambda row: 'test'
   grid = SQLFORM.grid(db.flavor)

The table flavor has a column referencing the table product. 

So, the grid displays the product column correctly now (with _format - this is where just 'format' doesn't work and '_format" does). However, when I add a new record to the flavor table (via the grid), I expect the product column in the insert record form to contain a drop down list of records from the product table to be represented by the same _format setting - perhaps I am making a wrong assumption? So this column in adding new record form ignores the _format. 

Is this by design? Isn't the format option supposed to work the same way in the new record form, as well as in the grid listing all the records?
