Hi All, View ******** <tr> <td><b>Student: </b></td> <td><%= text_field "student", "fname", "size" => 40, "maxlength" => 40 %></td> </tr> <tr> <td><b>Program: </b></td> <td><select id="student_program_id"

I am sure some of you can give me an insight into this. This is more towards the database design for the scenario below: Say for example, I have a person table and this person can have different address types. One could be Home and the other could be say Office. Should be model this Table people id fname lname Table addresses id person_id addr1 addr2 .... or Table people id fname lname

What''s the difference between these two? Objective: Trying to display the addresses of the students that has "has_many" relations with addresses <td><% @student.addresses.each {|address| "Address: #{address.addr1}<br/>"} %> </td> ****** did not work <% end %> This code worked: <td><% @student.addresses.each do |address|%>

Hi All, I need your suggestions for the following. I am still learning RoR and pardon my ignorance. I have say two tables. Table A : students Table B : addresses Table B has student_id as the foreign key to Table A If I am displaying the list of students and wanted to get individual students addresses based on their id, is the only option is to get the id from students controller method list

A while back, I had some doubts on the use of associations. I still haven''t got a satisfactory guidance so that I can spring ahead with the project. I am trying to understand from a ruby point of view on doing things. Basically I have a controller that gives me a list of students. And each student may have say home address and mailing address. Hence I can model as shown below. How do I

I found a reference to using attachment_fu and followed the lead of it but having an issue with the redirect_to that renders the fb:render tag - In my form I''m setting the canvas to false, file is being uploaded / save fine but when I attempt to redirect: redirect_to :action => :new, :canvas => true Unfortunatly it looks like my callback URL is getting printed twice, e.g.

Apologies first, because I need to ramp up on Ruby and coding Ruby in Rails, however it''s my 3rd day with this beast :) so I''m asking : When I added protected methods to the model before it was like: protected method.................... end Would this be a valid way to write a protected method as well ?: attr_protected :column1, :column2 Perhaps this particular call

May seem strange but I''ve gotten a couple requests from clients [2 out of 4] abt this.. generally the requirement is that they want to serve up slightly different content but from more or less the same app..

Readers, I have entered a file into r: ,column1,column2 row1,0.1,0.2 row2,0.3,0.4 using the command: dataframe<-read.table("/path/to/file.csv",header=T,row.names=1) When I try the command: dataframe[,2] I receive the response: NULL I was expecting: row1 0.2 row2 0.4 What is my error with the syntax please? Yours, r251 mandriva2009

is there a smart way of determining the number of pairwise present data in a data matrix with missings (maybe as a by-product of some statistical function?) so far, i used several loops like: for (column1 in 1:99) { for (column2 in 2:100) { for (row in 1:500) { if (!is.na(matrix[row,column1]) & !is.na(matrix[row,column2])) { pairs[col1,col2] <- pairs[col1,col2]+1

Hi, I was wondering is there any editor that can do autocompletion as shown in the tutorials on the RoR website in the windows or linux environment. If not do any one has sharable macros that comes with textpad or any other editors. Silvy Mathews

I am writing a custom function that uses an R-function from the reshape package: cast. However, my question could be applicable to any R function. Normally one writes the arguments directly into a function, e.g.: result=cast(table1, column1 + column2 + column3 ~ column4, mean) (1) I need to be able to write this statement as follows: result=cast(table1, string_with_columns ~

Hello, Can someone kindly tell what the heck creating a relationship does in active record? I understand the idea of joining the tables and such. But how do I use it? Is it available in a scaffold? How about when I want to view a record and want to see all the joined data from the other table? Do I have to manually code the data I want from the other table? Does this automatically make the
