db.t_stores.created_by is a reference field, so by default it gets a
"represent" attribute if the table to which it refers has a "format"
attribute. The other fields presumably are not reference fields (nor other
types of special fields that get default "represent" attributes), so they
have no "represent" function. Why are you trying to apply "represent"
functions to those fields anyway? Aren't they just string fields that
display what you want as is?
Note, as an alternative, you can do:
{{for item in all_items.render():}}
{{=item.created_by}}
...
The .render() method automatically applies "represent" attributes to all
fields that have them.
