I wanted a way to make a full control sitemap (editable changefreq, priority etc) and that can be auto generated with all my public views. I want a way to get a sitemap for any public controller and get urls with args as unique urls.

Well, to do this little job I figure a simple solution:

In the Models:

db.define_table(
    'seo_sitemap',
    Field('loc', 'string', requires=IS_NOT_EMPTY()),
    Field('lastmod', 'datetime', ),
    Field('changefreq', 'string', default='none',
          requires=IS_IN_SET(('none', 'always', 'hourly', 'daily', 'weekly', 'monthly', 'anual', 'never'))),
    Field('priority', 'string', default='none',
          requires=IS_IN_SET(('none', '0.0', '0.1', '0.2', '0.3', '0.4', '0.5', '0.6', '0.7', '0.8', '0.9', '1.0'))),
    Field('translated', 'boolean', default=True),
    Field('active', 'boolean', default=True),
)

if request.extension.lower() == 'html' and not (request.ajax or auth.user) :
    db.seo_sitemap.update_or_insert(loc=request.env.path_info)

work done! all my requests are take by path_info, now I just need to navigate in application without any user and do customizations at appadmin.

Lets write the controller (default.py) I use:

def sitemap():
    # Get urls
    urls = db(db.seo_sitemap.active == True).select()
    languages = sorted([(c, i[1]) for c, i in T.get_possible_languages_info().iteritems() if c != 'default'])
    if len(languages) <= 1: languages = []
    return dict(urls=urls, languages=languages)

And the view (default/sitemap.xml)

{{
loc = lambda l: XML("%s://%s%s" % (request.env.wsgi_url_scheme, request.env.http_host, l))
urlset = ['xmlns="http://www.sitemaps.org/schemas/sitemap/0.9"']
if languages: urlset += ['xmlns:xhtml="http://www.w3.org/1999/xhtml"']
}}<?xml version="1.0" encoding="UTF-8"?>
<urlset {{=XML(" ".join(urlset))}}>
  {{for url in urls:}}
    <url>
      <loc>{{=loc(url.loc)}}</loc>
      {{if url.lastmod:}}<lastmod>{{=url.lastmod}}</lastmod>{{pass}}
      {{if url.changefreq != 'none':}}<changefreq>{{=url.changefreq}}</changefreq>{{pass}}
      {{if url.priority != 'none':}}<priority>{{=url.priority}}</priority>{{pass}}
      {{if url.translated:}}
        {{for ref, name in languages:}}
          <xhtml:link rel="alternate" href="{{=alternate(url.loc, ref)}}" hreflang="{{=ref.replace("-", "_")}}"/>
        {{pass}}
      {{pass}}
    </url>
  {{pass}}
</urlset>

That is it. Now whe I request /appname/default/sitemap.xml  Will return a complete sitemap with translated versions. Hum.. well the ?locale= thing is the way I use to change language, but figure out your own way.

That's all folks..
