This validation goes through and validates each individual word in your string. This goes in whatever model you’re validating. “Subject” can be any of the symbols in your model and doesn’t need the : in front of it.

errors.add(:subject, “cannot have words more than 26 consecutive characters”)
end
end

The default Rails way of doing validate error messages is sort of silly. It works, but it doesn’t work that well. You can iterate through all the error messages in a very constrained way (error_messages_for) or you can display errors on fields one by one (error_message_on). I kind of want functionality from […]

For those of you who are not web developers I’m sure you won’t understand my pain, but let me assure you that if you ARE an Internet Explorer user, webdev or not, […]

So. The issue:
I couldn’t get the radio_button or check_box tags to work with rails. They kept telling me:

wrong number of arguments (0 for 1)

Which didn’t make any sense since I was supplying arguments correctly. I eventually tried making a radio_button in a different view and it worked fine. I found out […]

one of the most amazing frameworks for dynamic content.. and what’s my problem? i cant figure out where the hell the best place is to place static content.
my first thought was “sure i could just dump a file in /app/views”. seems like a reasonable solution.. but of course rails won’t route that correctly.
so […]

I’ve been messing around with MySQL Query Browser.. Quite honestly it’s a piece of shit. Actually kinda surprises me that MySQL even came up with the damn thing. I haven’t been too impressed with MySQL/InnoDB lately either.. but.. yeah.. anyway. So I’ve been having problems with it and doing foreign key stuff […]
