I''m setting up a basic shopping cart type app, and the products we have will have multiple options. Size, color, etc. I''m trying to figure out how I can collect the the options that are selected when a user adds the item to their cart. An OptionSet is a group of options ("Size", "Color", etc), and an ItemOption is the option itself ("12 oz",

Hey folks, This is my first message to the mailing list so please let me know if I mess something up. I'm trying to use the selectcommand for the mclistbox but I'm not very adept at using functions. Ideally I'd like to change the editor text when a different list item is selected but any help using the selectcommand would be appreciated and I think I could get the rest working.

I couldn't find any reference to this in the FAQ, but is it possible to sort a dataframe by multiple columns? I've created some code, similar to the following: nspr.code <- sp.results$sp.code[order( sp.results$sp.code )] nspr.tpa <- sp.results$tpa[order( sp.results$sp.code )] nspr.code <- as.character( levels( nspr.code ) )[nspr.code] nspr.tpa <- as.numeric( levels( nspr.tpa

Hi there, I have been using the example provided bellow for a while, and It was working without any problem. Nevertheless, just since 2-3 days is not working, probably because I did update.packages(). I have tried to re-install the older versions of the packages Hmisc() and xtable(), but still does not work. Can you run this example, and tell me if you got the same problems? I use

Thanks to everyone who responded to my first set of questions. Not only did I get my questions answered but I improved my code and learned a couple new things. I think I prefer the mailing list over IRC... easier to follow :-) I have some more questions if you don''t mind. Some are Rails related and some are Ruby related. 1) This is concerning displaying error messages. I am assuming

Hi I''m new to Rails and I''m struggling with a ''has-one'' relationship. I''m trying to save product and image data in seperate tables with one to one relationship. I''m assuming the problem lies in the controller method below but can''t work it out. The models contain the has_one and belongs to statements, and I tried swapping these

I have read extensively on has_many but cannot find an explicit example on how to do what I need. I am a newbie, but can grasp it if I see it in a working example. Here is my scenario... I have a form which I can add a TODO item (patterned after http://darkhost.mine.nu:81/~vince/rails/tutorial.html). I have the form working perfectly so I decided to modify it a bit to add more functionality.

Hi all, I am using "validates_presence_of" for validating all fields of my registration form. It is working fine and generating custom error message as mentioned. Also clearing all fields. How can restore those fields which are already filled. Problem is "validates_presence_of" clearing (blank) field if it fails, instead of restoring fields which are already filled. Help.

I''m new to Rails (and liking it!) and I have multiple controllers, each of which has a method which uses a view template which is identical to what the others use. I would like to be able to have just one template to maintain that they can all use. What is the customary way to do this? I tried using render_action to specify the template explicitly, and it "works". But I

Hi Is there a render_action matcher to go with render_template? I can''t see any mention of one in the docs. Do you have to still do it old- school? Thanks Ashley
