Hi all,

I use rescue\_action\_in\_public(e) and rescue\_action\_locally(e) methods  
for  
catching the controller exceptions. I render some templates, also the  
standard error static html pages. Is there any other standard way to  
handle  
controller exceptions?

checkit:

def action\_in\_controller

# a couple of bad statements that raise errors; per error, it gets

sent to the

# rescue clause that catches that specific error:

foo = 5 + “string” # TypeError  
bar = ActiveRecordModel.find(23452345234523452345234) #  
RecordNotFound  
blah = “nochie” + un\_inited\_var  
…  
…  
…  
rescue TypeError  
render\_text “we added two bad datatypes”  
rescue RecordNotFound  
render\_text “we looked up a record that doesn’t exist”  
rescue  
render\_text “generic rescue”  
end
