Is there a "normal" way to override the behavior of validator methods (like validates_presence_of) for updates vs. creation? For example, in the AWDR example store program, the User class validates the presence of the password and its length - which makes sense when the user entry is created. But what if you wanted to provide an update form that updates just certain items

I have a before_filter in ApplicationController in which I want to check if the current location is the same as a certain route, so that I only redirect non-logged in visitors to the "join" page if they''re not on that page already. The code I came up with is a bit ugly: redirect_to join_url unless (@logged_in or action_name == "join") I''m pretty sure

I am new to Ruby on Rails. I have read a lot, and bought several books, and now I have started to implement a modified "shopping cart", following the AWDWR-book, with modifications to suit our application (subscriptions and memberships). Having done up to chapter 7 I have had no real problems, except one: Since our customers are Swedish I need the screen names, texts etc to be in

But this time it keeps telling me:- "Error in lm.fit(x, y, offset = offset, singular.ok = singular.ok, ...) : 0 (non-NA) cases" The model is:- fm1 <- lm(TS.CM ~ AGE + SEX + HFE.Y.01 + TFC2B.01 + HFE.Y.01*TFC2B.01, data = IRONresults, subset = DIAG2.1D == 0) summary (fm1) TS.CM is a

I just occasionally found a vulnerability in Linux libc (actually, some of the versions seem not to be vulnerable; my Slackware 3.1 box was though). Unfortunately, I have no time for a real investigation right now, but

Dear All, I have been running a successful and very stable call center PBX based on 0.7.1 release. I need to be on this release because of a number of features that I have complied from 3rd party patches, for the call center. I will not be able to upgrade to release 1 until the patches catch up and I have done the required testing. The system was very stable until two days ago. The changes made

Hello, Is there a common way of stripping html tags from a string? Right now I''m just calling gsub!(/<.*?>/, ''''), but with a background in PHP and always having used its strip_tags() method, I wonder if the Rails community has standardized this fairly common task with something a bit less simpleminded than my quick fix. Thanks! Zack -------------- next part

All, Thanks for the responses. There were two things I had to do to get this to work. The first thing was I had to change the readonly attribute in the smb.conf to NO. I also noticed that there was an error in my /etc/fstab so that the options were not read in for some reason. Once I fixed this and re-mounted the filesystem with the ACL option, I was able to do what I needed to do. Thanks
