Hi all, I want to make extra columns in my datafile where the id of every groupmember is mentioned in separate columns. To explain it better see the example: id<-c(1,2,3,4,5,6,7,8,9,10,11,12) group<-c(1,1,1,1,2,2,3,3,3,3,3,3) a<-as.data.frame(cbind(id,group)) a id group 1 1 1 2 2 1 3 3 1 4 4 1 5 5

I started a php-based website a few months ago with a buddy of mine on netfirms.com. I was perusing their knowledge base and I came upon a quick-start for something called Ruby on Rails. Since then I have immersed myself in RoR. I''ve done the tutorials, I''ve purchased the books. But, I could never get even a sample RoR app to work on netfirms. 500 server errors.

The is something I wrestle with a bit when I construct joined queries.. Perhaps some experienced insight will straighten this out for me. Say you have two tables with two models, ''authors'' and ''posts''. an author has_many posts, a post has_one author. You need methods to do the following queries: find_author(postid) find_posts(authorid) And you are doing a

Hi, I wonder why error_messages_for take strings as params instead of instance variables. error_messages_for ''user'' instead of error_messages_for @user ''user'' is translated into @user eventually. If so, who not take the instance variables directly? Is there any reason for that? Thanks in advance. Sam -- Posted via http://www.ruby-forum.com/.

Hi all, I am trying to change the default formatting for the error_messages_for. To quote from the ROR manual: /////////// error_messages_for(object_name, options = {}) Returns a string with a div containing all the error messages for the object located as an instance variable by the name of object_name. This div can be tailored by the following options: header_tag - Used for the header of

I have a model Area which has_many Streets. The Area has a couple of attributes of its own but mostly I want to be able to add/delete/update Streets for a particular Area, but all on one page rather than having a separate view for editing a Street. I''ve managed to get a form displayed with a row for each Street already assigned to the Area by using form fields with

Hi, just a simple question between error_message_on / error_messages_for ... Well, if you use error_messages_for in your web page, there is no problem even if anObject==nil (for example , the first time you load your form) whereas error_message_on must be use with an instanciated object ... So, you always has to double check if anObject is not nil before using error_message_on ? I

Hi guys, I just upgraded to the latest version of Rails 1.1 and am getting some odd error messages. Specifically, I have the line: <%= error_messages_for ''user'' %> at the top of one of my .rhtml files and of course a variable @user. When an error occurs when saving ''user'', instead of getting the error message (which happened fine in Rails 1.0), I now

How would I set up a model stub so that <%= error_messages_for ''some_model'' %> doesn''t complain? I started going down this road: @some_model.stub! (:errors).and_return(ActiveRecord::Errors.new) but it seems like a long, hopefully uneccessary road. Cheers, Michael
