This works well.
I guess I failed to clarify: 2. Is there a way of following this example
but deleting rows upto a certain limit, say anything above 50 like in this
example:...
Should have been retain latest inputs up a certain limit e.g. the last
50, and delete older inputs.
I got a better

Show the code for "query". Looks like it might include a Set object where a
field or value is expected.

Sorry. I got it.

You can delete row this way!!
db((db.table.id==id_s)&(db.table.created_by == auth.user.id)).delete()
if you want delete rows upto a certain limit so you can you put this quarry
under for loop.
Best,

I have tried this example but I get this error below:
db(query).delete()
File "/usr/local/lib/python2.7/dist-packages/pydal/objects.py", line 2277, in
delete
ret = db._adapter.delete(table, self.query)
File "/usr/local/lib/python2.7/dist-packages/pydal/adapters/sqlite.py", line
86, in
think you can do it by store the user created id (auth.signature or code it
by your self) in your table and use it as a condition
*e.g. not tested*
query = ((db.table.id == id) & (db.table.created_by == auth.user_id) )
db(query).delete()

Hi.
I happened to have the same issue as this:
Specifically (syntax-wise) how does one delete a specific table row,
but INDEPENDENT of the ".id" field?
for example, lets say that I have the following rows in a database
table:
bid.idbid.bid_id
1LJWI
2LJWJ
3LJWK
4
I hope this is a simple question:

bid.id bid.bid_id

4 LJWL
I know that
rows = db(db.bid.id 0).select(limitby=(1, 2), orderby=db.bid.id)
rows.first().delete_record()
Test that out a bit see if it does what you want.

This does delete the row from the actual database table
acts on the database
row.delete_record()
row.update_reocrd()
works on the recordset.
row.delete()
row.update()
This is because delete() and update() are python builtin dict functions, that
is why it uses this naming scheme.

A Rows object is just an array with database specific operations
added. So you can go
rows = db(db.table.id 0).select()
rows[n].delete_record()
if you know what (n) is.
first() syntax has been added since the manual was published. However,
it is just a shortcut to the following, but returns
12 matches
