[web2py] Key error that i don't understand based on the cookbook.

[bussiere adrien]

here is my db.py :

db.define_table('ImageFilmPreview',
   Field('Nom'),
   Field('date_Creation','date'),
   Field('Tag','list:reference Tag'),
   Field('FamilleTag','list:reference FamilleTag'),
   Field('Type','list:reference Type'),
   Field('Valeur_Ticket','double'),
   Field('Description_Courte'),
   Field('Description_Longue'),
   Field('Image'),#a revoir 
   Field('Texte_contenu','list:reference Texte_contenu'),
   Field('Link','list:reference Link'),
   Field('Note_divers','list:reference Note_divers'),
   format = '%(Nom)s')


db.define_table('Film',
   Field('Nom'),
   Field('UrlPreview'),
   Field('date_Creation','date'),
   Field('date_Publication','date'),
   Field('Tag','list:reference Tag'),
   Field('FamilleTag','list:reference FamilleTag'),
   Field('Type','list:reference Type'),
   Field('Valeur_Ticket','double'),
   Field('Description_Courte'),
   Field('Description_Longue'),
   Field('ImageFilm','list:reference ImageFilm'),
   Field('ImageFilmPreview','list:reference ImagePreview'),
   Field('Texte_contenu','list:reference Texte_contenu'),
   Field('Acteur','list:reference Acteur'),
   Field('Avis','list:reference Avis'),
   Field('Link','list:reference Link'),
   Field('Note_divers','list:reference Note_divers'),
   format = '%(Nom)s')


here is my default.py :

def admindanakFilm():
Line 88:    form1 = crud.create(db.Film, next='admindanakFilm')
    films = db(db.Film).select(orderby=db.Film.id)
    film = db.company(request.args(0)) or redirect(URL('admindanak'))
    form2 = crud.update(db.Film, film, next='Film')
    return locals()


and here is my template :
<h2>Companies</h2>
<table>
<h2>New Film</h2>
{{=form1}}
<br>
<h2>Film edit</h2>
{{=form2}}
<br>

{{for Film in films:}}
<tr>
<td>{{=A(Film.Nom)}}</td>
<td>{{=A('edit', _href=URL('admindanakFilm',
args=Film.id))}}</td>
</tr>
{{pass}}
<tr>
<td></td>
</tr>
</table>


and it gave to me :
