[web2py] Re: Manipulate Rows Object and/or SQLTABLE
@Martin - I like that! I think the ability to add rows and columns in an obvious way is something that has been missing. SQLTABLE needs this feature for quick 'views'. However, for DB rows, I think Mr Freeze's Webgrid might be the right vehicle for further development mainly because we really need the pagination and set-up options. I like the idea of using jqGrid, but it just seems a bit too complex. We need things which 'just work' as part of the framework.

Re: [web2py] Re: Manipulate Rows Object and/or SQLTABLE
Sorry for posting what I'v already posted, but it looks like my post
on the patch to make SQLTABLE work with Rows object with added virtual
fields was lost.
I think the easiest solution to add a column to select result and view
the result in SQLTABLE wold be something like:
class ExtraFields:
def new_column(self):
if self.some_field_in_select==' something':
return A('some_action_link', _href=URL(
f=some_action_controller_function,
args=[self.id]))
else:
return A('great thing', _href='http://www.web2py.com')
rows=db(db.some_table).select()
rows.setvirtualfields(some_table=ExtraFields())
rows.colnames.append('some_table.new_column')
table=SQLTABLE(rows)
This will give an exception telling that
sqlhtml.py:SQLTABLE.__init__
can't do
field = sqlrows.db[tablename][fieldname]
because there is no 'new_column' in the database.
It wants to get the field from the db model to know how to render it.
This doesn't matter when we add a new field to select result
because the new field shell(and will by a view) be cast to string.
The patch:
change
sqlhtml.py:SQLTABLE.__init__
field = sqlrows.db[tablename][fieldname]
to
try:
field = sqlrows.db[tablename][fieldname]
except:
field = None
change
sqlhtml.py:SQLTABLE.__init__
if field.represent:
r = field.represent(r)
to
if not field:
pass
elif field.represent:
r = field.represent(r)
---Now we are able to include a new field in SQLTABLE
containing anything(text, link, image, button, form, whatever)
depending on row contents(in ExtraFields.new_column(self): 'self' is a single
Row in Rows object returned by select) ,
by adding the field to db().select() result.
---Limitation:
in
rows.colnames.append('some_table.new_column')
rows.setvirtualfields(some_table=ExtraField())
'some_table' shell be a table mentioned in select and present in
the db,
otherwise
'some_table' will be added as a sub dict to Row objects
and you will not see it in SQLTABLE.

[web2py] Re: Manipulate Rows Object and/or SQLTABLE
The function looks interesting, but I didnt understand how to create
the cols var.
def mytable(rows, cols):
return TABLE(*[TR(*[TD(row[c]) for c in cols]) for row in rows])
I would be grateful for an example how it might work.
I did have this other idea to include an extra column, but I imagine
that it's not so elegant as above.
rows = db(db.test.id0).select()
extras = list()
for row in rows: extras.append('whatever')
for row,extra in zip(rows,extras):
print TR(TD(row.id),TD(extra))

If all you need is an extra column have a look at col3 in SQLFORM
