Hi,

there is somthing, that I do not understand.

class MyController \< ApplicationController

def index  
…  
end

def my\_def  
redirect\_to :action=\> “index” unless params[:id]

```
my_model = MyModel.find(params[:id])
...

```

end  
end

when I try to call “my\_controller/my\_def” without an id in y browser,  
then the find-statement will is evaluated ☹ why?!?

thanks Guido

because redirect\_to is not a return… it’s a method call… use the  
following form:

def my\_def  
if params[:id]  
my\_model = MyModel.find params[:id]  
else  
redirect\_to :action =\> “index”  
end  
end
