Hi all, I''ve upgraded my system to Rails 1.1.1 successfully. After much looking I haven''t found out how to migrate an existing application to a new rails version though. What is the procedure, if any, for upgrading the application I''ve developed in 1.0? Is there a script I need to run? -- Posted via http://www.ruby-forum.com/.

I made a mistake when making my first app. I did not use the: ruby script/generate model <modelname> method for creating my models. I more or less hand crafted each og them. Is there a way to go back so I get my db migration scripts to populate? -- Posted via http://www.ruby-forum.com/.

Hi, I need a relatively simple image api for the app I''m writing. I need to copy photos, rename them, and re-size them to put them in a standard format. I tried using RMagick/Imagemagick, but the photos would be corrupted on re-size, so I''m looking for some suggestions. -- Posted via http://www.ruby-forum.com/.

Hi, I have three tables, a domain of Sites, a domain of Users, and a junction of Sites_Users with the tables named as such. My RoR application has a model and controller both User and Site.

I feel awful asking such a basic question, but here it goes.... I have a controller, "NewsController". The user enters and the "list" action is called and I populate an instance variable "@news" which contains all the elements I''d like to display using a form. The user then changes something and the "update" action is called. Is

Hi: Sorry if this is a painfully stupid question... I have some data I need through the life of someone''s session. In the application controller, I grab the data and store it like so: session[:foo] = @foo Now, whenever I need to access data about foo I don''t need to cause any DB io, I can just grab foo from the session (it''s very small fyi). Here''s what I

I have chunk of data that I need for the life of the session. I am going to use it for selects through out my app. Is the best place to keep this data in the session? Is the session easily spoofed or cracked? While viewing the data is not critical in itself, spoofing it could cause me massive headaches. -- Posted via http://www.ruby-forum.com/.

Hi! I just ran the first few Rails tutorials and I''m really impressed at how quickly I was able to get something up and running. I''m slowly emerging from the stone ages, and leaving my powerbuilder behind ? yes, I know, keep the snickering to a minimum please! I started into J2EE/STRUTS, but was quickly frustrated by how long it would take to code anything but relatively

Hi All, Could anyone tell me, how to correctly install MySQL4.1 on Centos 5 ? By default Centos 5 comes with mysql5? If I will compile mysql4 from sources to separate prefix, some features may be unavailable (unix sockets for example). I?m moving some critical application (online booking) based on java, tomcat5, mysql4.1 from old server fedora 4 to new server running Centos 5. So, I don?t

I was up late last night trying to find the cause of this, but I''m stumped. I have this relatively simple controller to load up a bio. It''s basicly id, name, desc, type (I use STI). class BioController < ApplicationController layout ''layouts/singlepanel'' def index @bio = Bio.find(:all, :conditions => [''site_id = ?'',

Instead of making a form to upload one picture at a time, I''d like to have the File Column plugin accept a directory, and have each picture be uploaded and thumbnails created (w/ RMagick). Has anyone done this? Anyone have a good idea where to start if I were to do it on my own? Thanks, Ben Lisbakken -- Posted via http://www.ruby-forum.com/.

I am trying to create a generic person model. Then subclass it as either a professor or an author. The only problem is that since some professors are authors, I don''t want duplicate entries.

I am going for a dedicated hosted server for a rails app I am working on, and have a choice from several different operating systems.

Can a ruby on rails app obtain the ip of the server it is running on? I''d like the application to be able to determine x set of data is for y data, for example: These domains all point to the same ip... mydomain-1.com mydomain-2.com mydomain-3.org I can obtain the domain name from the request by using: @request.domain I''d like the application to grab the corresponding ip for

I have some files stored in db. When I try to download these I only get 65535 bytes from the database even if the file is a lot bigger. Is it a Rails setting I''ve missed or a database setting? Anything else? Using Rails 1.0, WinXP and MySQL4.1 /Marcus

Right now rails doesn''t support composite keys, that is id1, id2, and id3 are in the primary key of the table. Does anyone know if this is being discussed for future versions, or is it pretty much out of scope? -- Posted via http://www.ruby-forum.com/.

Hi, I think I''m doing this the right way, but can''t get it going. I''m building a menu from the values in a mySQL table, and want to build it on the fly. This is something that should be working but only works halfway: <% @pages = Page.find(:all, :conditions => [''site_id = 4'']) %> <% @pages.each do |p| %> xyz <%p.id%> <%
