[web2py] Edit an article

[BlueShadow]

Hi,
I got a page where every author can write new articles (article table: 
content title...) but I don't really now how I can allow the authors to 
edit the articles without giving them access to appadmin. Is there an easy 
way to allow that?
like filling this form with the article?
default.py:
def newArticle():
    db.Article.Content.widget = advanced_editor
    form=SQLFORM(db.Article,fields=['Title','Content','Sources'])
    if form.accepts(request.vars,session):
        redirect(URL(r=request,f='Articles'))
    if form.errors:
        response.flash='Error in Form'
    return dict(form=form)

newArticle.html:
{{extend 'layout.html'}}
<h1>Write a new Article</h1>

{{=form}}

thanks for your help
