Combobox problem

Rails
1

Hi,

ich watched the tutorial complex forms 3 (http://railscasts.com/
episodes/75) and included it into my application. everything works
fine so far but if i want to change

Code : ruby - fold - unfold

  1. <%= f.text_field :installed_since%>

in

Code : ruby - fold - unfold

  1. <%= f.date_select :installed_since %>

it comes to the following error message when i run the function create
or update:

“We’re sorry, but something went wrong.
We’ve been notified about this issue and we’ll take a look at it
shortly.”

I can see the date_select component and change the date everything is
fine, just when i hit the button it comes to this wiered message.

can anyone help me ?

where do you see this message?
it’s what users get to see for EVERY error in production environment.
how are you developing? on your live server?
what about development.log, what error message do you see there?

the message shows up when create or update is excecuted. eg you hit a
button update then you get to the side with the text “We’re sorry, but
something went wrong.
We’ve been notified about this issue and we’ll take a look at it
shortly.”

the error appeared for the first time and only when date_select is
involved. i am just developing on my own machine and i am running the
developer mode. i could not find anything in the log yet but i am
still looking.

the question is if i am the only one where this message appears? the
problem ist date_select but what is my mistake?
