Well, I’ve been testing out my code in production mode, in anticipation
of being able to show off my site soon. Unfortunately, all is not going
as expected. Production mode… well, its behaving differently than
development did. I’ve already had login validation issues, and now it
seems that my PM system is broken.
If a user enters a non-existent username as a recipient of a message, I
now get a 500 internal server error. In the log, I get: TypeError
(can’t modify frozen hash) at line 108. Line 108 is “@message.sender =
find_user_and_messages.get_user_id.to_s”, which shouldn’t even be
executing (its also a poorly named method, but thats not the point). In
development mode, if a user didn’t exist, the while loop would recognize
that, and simply return errors. Now it fails to do so. All my other
validations on the message seem to work fine, its just this one that
fails. The appropriate code:
if
#other validations on the message
else
while (i<hold.length)
if User.find_by_screen_name(hold[i]) == nil
@message.errors.add("Recipient " + hold[i] + " doesn't
exist!")
@message.destroy
break
else
if trfa == false
@message.recipients = “,” +
User.find_by_screen_name(hold[i]).get_user_id.to_s + “,”
trfa = true
else
@message.recipients = @message.recipients +
User.find_by_screen_name(hold[i]).get_user_id.to_s + “,”
end
i+=1
end
end
@message.sender = find_user_and_messages.get_user_id.to_s
@message.save
flash[:notice] = “Message Sent!”
redirect_to hub_url and return
end
And as a secondary question, what is it that makes Rails behave
differently in production mode? And how do I go about avoiding surprise
behavior changes in future apps?
Thanks for your help in advance
