roman ich hab das vorhin abgeändert..warn tippfehler in der mail aber das ist
es leider auch nicht .
ich finde mein irgendwie seltsam weil sobald ich meine methode z.B in
index_zwei umbenne kommt keine fehlermeldung mehr aber die daten werden auch in
der view nicht angezeigt ! aber wenn ich meine methode index nenne, was ja ach
so sein sollte , kommt diese fehlermeldung !
scheint irgendwas mit der controller nicht zu stimmen. die view scheint korrekt
zu sein ! hoffe ich

Subject: Re: [Rubyonrails-ug] controller problem !
Falls @depth = params[:books][:depth] noch so in Deinem Controller steht
kann es auch nicht gehen. params[:books] gibt es nicht und ist somit nil.

ja das stimmt es heisst f.submit ;-) bin jetzt zwar ein schritt weiter aber
nicht ganz ;-)
das problem ist das es zwar für source einwandfrei funktioniert aber für die
anderen variablen leider nicht ! ich hab jetzt die andere variablen
auskommentiert und gebe es in der view aus und prompt kommt der fehler wieder :

sorry, es muss f.submit und nicht f.submit_tag heissen.
Falls es wieder nicht klappen sollte, schick mir mal den Ausschnitt aus dem
log, welcher beim abschicken des Formulars generiert wird. Mich interessiert
vor allem der params-Hash.
