[web2py] Re: Getting only the latest "version" in a query of items with versions.
I suppose your right, but I was a little thrown, by the: max(variable_here) That was mentioned was not the solution at all, I kept looking for ways to use max as a function. My issue now, is that the group by doesn't like me getting all the tables I want in the return.

[web2py] Re: Getting only the latest "version" in a query of items with versions.
Grr, And now I can't get the db.item_version.ALL without Postgresql panicking about not having the item in the group buy. How do I get the fields in the result set? Do I need to place it in as a belongs or something? latest_versions = db( (db.item.id == db.item_version.artifact_id) & (db.item_version.id > 0) ).select(db.item.ALL, db.item_version.ALL, db.item_version.version_date.max(), groupby=db.item.id) On Thursday, August 25, 2016 at 8:29:09 AM UTC+3, Encompass solutions wrote: > > Does this seem sensible?

[web2py] Re: Getting only the latest "version" in a query of items with versions.
Does this seem sensible? It seems to work with my initial tests. latest_versions = db( (db.item.id == db.item_version.artifact_id) & (db.item_version.id > 0) ).select(db.item.ALL,db.item_version.version_date.max(), groupby=db.item.id) the .max() feature, at least what I found, was totally undocumented.

[web2py] Re: Retrieve custom form input/select value in case of errors
Thank you Mirek for that.
Like that it works:
{{=INPUT(_type='text', _name='book_title', _id='book_title',
_value='form.vars.book_title')}}
But web2py don't load the default value set in the table (even before it
was like that but I've add it with _value.
For having a complete solution I must do something like that:
{{if form.vars.book_title:}}
{{book_title_value = form.vars.book_title}}
{{else:}}
{{book_title_value = 'My book title'}}
{{pass}}
{{=INPUT(_type='text', _name='book_title', _id='book_title', _value=
book_title_value)}}
