Here's a good function header given the following:
I wrote the below code

    T = current.T
    s3db = current.s3db
    s3 = current.response.s3
    settings = current.deployment_settings
    team_name = settings.get_hrm_teams()
    tablename = 'pr_group'
    table = s3db[tablename]
    _group_type = table.group_type
    if (team_name == 'Teams'):
        _group_type.label = T('Team    Type')
        table.description.label = T('Team    Description')
        table.name.label = T('Team    Name')
    _group_type.default = 3
    s3.filter = ((table.system == False) & (_group_type == 3))
    if (team_name == 'Teams'):
        s3.crud_strings[tablename] = Storage(label_create=T('Add    Team'), title_display=T('Team    Details'), title_list=T('Teams'), title_update=T('Edit    Team'), label_list_button=T('List    Teams'), label_search_button=T('Search    Teams'), msg_record_created=T('Team    added'), msg_record_modified=T('Team    updated'), msg_record_deleted=T('Team    deleted'), msg_list_empty=T('No    Teams    currently    registered'))
    s3db.add_components('pr_group', org_organisation_team='group_id')
    def prep(r):
        create_next = URL(f='group', args=['[id]', 'group_membership'])
        teams_orgs = settings.get_hrm_teams_orgs()
        if teams_orgs:
            if (teams_orgs == 1):
                multiple = False
            else:
                multiple = True
            ottable = s3db.org_organisation_team
            label = ottable.organisation_id.label
            ottable.organisation_id.label = ''
            crud_form = S3SQLCustomForm('name', 'description', S3SQLInlineComponent('organisation_team', label=label, fields=['organisation_id'], multiple=multiple), 'comments')
            filter_widgets = [S3TextFilter(['name', 'description', 'comments', 'organisation_team.organisation_id$name', 'organisation_team.organisation_id$acronym'], label=T('Search'), comment=T("You    can    search    by    by    group    name,    description    or    comments    and    by    organization    name    or    acronym.    You    may    use    %    as    wildcard.    Press   ...
