Hi everyone,  
I was just trying to catch some exceptions in my  
app,  
for “Record Not Found” I used this  
in my application.rb file  
rescue\_from ActiveRecord::RecordNotFound, :with =\> :record\_not\_found  
rescue\_from ActionController::NoMethodError, :with =\> :show\_error

private

def record\_not\_found  
render :text =\> “404 Not Found”, :status =\> 404  
end  
def show\_error(exception)  
render :text =\> exception.message;  
end

and was quite successful but for “NoMethodError” I am trying the same  
but It  
isn’t working at all. Can anybody help me?  
Thanks in advance,  
Shahroon

Oh Yeah my mistake it was  
rescue\_from NoMethodError, :with =\> :show\_error  
but now I am following this procedure but no success in “NoMethodError”

rescue\_from NameError, :with =\> :handle\_exceptions  
rescue\_from NoMethodError, :with =\> :handle\_exceptions  
rescue\_from ActiveRecord::Rollback, :with =\> :handle\_exceptions  
rescue\_from ActiveRecord::StatementInvalid, :with =\>  
:handle\_exceptions  
rescue\_from ActiveRecord::RecordNotFound, :with =\> :handle\_exceptions  
rescue\_from ActionController::UnknownAction, :with =\>  
:handle\_exceptions  
rescue\_from ActiveRecord::RecordNotFound, :with =\> :handle\_exceptions  
rescue\_from ActiveRecord::StaleObjectError, :with =\>  
:handle\_exceptions  
rescue\_from ActiveRecord::RecordInvalid, :with =\> :handle\_exceptions  
rescue\_from ActiveRecord::RecordNotSaved, :with =\> :handle\_exceptions  
rescue\_from ActionController::MethodNotAllowed, :with =\>  
:handle\_exceptions  
rescue\_from ActionController::MethodNotAllowed, :with =\>  
:handle\_exceptions  
rescue\_from ActionController::InvalidAuthenticityToken, :with =\>  
:handle\_exceptions

private

def handle\_exceptions  
render :action =\> ‘500.html’,:text =\> ‘This is an error’, :status =\>  
500  
end

Any ideas how to solve this problem?

Because ActionController::NoMethodError doesn’t exist. It’s just plain  
NoMethodError (possibly ::NoMethodError but I don’t think that’s  
needed here)
