I am using some constants that should be visible in the controller and  
in a view.

Declaring the constant in the controller does not make the constant  
visible in the view.

So my question:  
Where can I declare the constant to be visible in all views and  
controllers ?

Thanks a lot in advance  
Christian

Set a instance attribute in the controller via before\_filter.

Christain-

```
I usually put my constants in the environment.rb file. This way they

```

will be available everywhere in the whole app. just remember to  
restart the webserver after makig changes to them.
