Hi Massimo, thanks for your answer, basically I need the row

making a query. But there is a way to know the table that belongs
an after update callback without passing explicitly the table object?

Let's say something like:

model:

from mymoduleimport my_after_update_callback

db.mytable._after_update.append(my_after_update_callback)

mymodule:

def my_after_update_callback(s,f): row = get_callback_row()

 table = get_callback_table()



Updates do not involve fetching the updated records from the database, 
so the DAL does not have any Row objects to provide to the callback. 
If you need the updated records, you'll have to fetch them yourself 
within the callback based on the Set:


|
rows =set.select()
|

Regarding the tablename, you can extract it from the Set as well. In 
most cases, something like the following should work:


|
table =set.query.first.table
|

Note, that will be the actual DAL Table object -- if you want the 
name, you can do set.query.first.tablename.

There is another thing:

Related to this, I am working with the experimental haystack plugin for 
whoosh, but I have made some changes (for using the whoosh backend with 
python3 and other things), but I look that the Github project page has 
no updates and there are unattended pull requests. Is the haystack 
plugin dead?


Greetings.

Hi, I am building a module (plugin) that is using some "after insert"
and "after uptade" dal callbacks. The tables has references
(relations)
and I need to obtain the referenced table string format instead of
it's
id in the callback, and I need it to be generic. How can I achieve
that?

Greetings.
