Is there any reason to avoid using postgresql for small web apps? That is, is it''s overhead so large that the lighter MySQL will work substantially better for small apps on small machines? Or are they very similar in performance and configuration? I''ve used MySQL but postgresql has its appeals and I''m wondering if I need to keep MySQL around at all. On the other

Hi, I was wondering if some of you have had to keep more than one version of Rails on your machine at a time? If you have more than one customer, they may have different requirements. You might need to work on a pre-existing app that is not scheduled to be moved to a newer version of Rails right now. How is the best way to deal with this? thanks, jp -- Posted via

Hi, Nuby on Rails here trying to bring up an existing app on a new installation. The whole ruby/rails/mysql/lighty installation was done per the much touted "hivelogic article" that runs through all the steps. I am running into a permission error when I try to do a rake migrate to set up a session database needed by this existing app. Extracted from the trace... ** Execute

I figured I pose this to the list and see if any one can build a better mousetrap. The problem: 1. Store hierarchical data in a database, but without knowing the hierarchy beforehand. 2. Allow the user to define there own hierarchy, and allow the system to support multiple hierarchies. Call it a cataloging system, we have an object and we want to add data about that object to the system. Now

I tried to keep track of the number of access to a specific controller. I declared ''@@mycount = 0'' in the controller class. The methods in the controller will increment the @@mycount (@@mycount = @@mycount + 1) and print the value to the html page and show in the browser. The value is always 1, no matter how many times I access the controller and its action(s). Is this

When you put up a page with a form on it and the top item is a text field it would be nice to have that field already focused instead of forcing the user to click in it before they start typing. Is there a rails (i.e. probably Prototype) way of giving focus to a field? I did some searching and found nothing. thanks, jp P.S. I''m on a Mac. Perhaps a winoze and/or unix automatically

Hello, I just started playing with RubyOnRails. It is indeed fascinating! I have a question about using rails models to connect to backend Java (i.e. EJBs) instead of database. Any pointers will be appreciated. Thanks and Regards, Khaled -- Posted via http://www.ruby-forum.com/.

This isn''t Rails or Ruby related, but I just need some advice and thought I''d ask the bright individuals here. I want to start my own blog but I''m not sure where to begin. I don''t want to get a blogger account because I want to have my own domain. Blogger also doesn''t have many features. My hosting service is 1AND1 so it supports php, cgi and mysql.

I''ve looked for DIFF tools for OSX but haven''t found anything good yet. Tried guiffy (http://www.guiffy.com) but it''s very slow and the folder comparison doesn''t indicate a change until you drill down to the level with the difference which kinda defeats the purpose. I''m missing TortoiseSVN and the diff tool that comes with it. Any suggestions for

Hi, Is there a way to test if a certain (local) variable has been initialized? I''d like to do something like if isset(myvar) and myvar.true? #some code else #default behaviour end I have a lot of shared views that I call with params such as { show_pager => true Instead of having to explicitly say show_pager => false it should be possible to make false a default value, right?

Ok, so this is kinda out of the blue... but I''ve been looking at Google Base and thinking that it''s got some really good ideas in it. Especially the way you can create your own "type" of item with its own custom attributes, like date range, location, number, text, etc. Kind of like defining a database with a GUI, but not exactly. It seems really interesting to me, from

I am checking the file size of an uploaded file and storing it in a filesize column. It will work just fine when the user uploads any files other than images (jpg,png,gif). Word, Excel, Powerpoint, .zip and more all work fine. This is my model asset.rb that handles the file upload. def newfile=(newfile_field) self.filename = base_part_of(newfile_field.original_filename) self.filetype

Hi, I''m a little confused about sessions. I have two objects, object "Apple" and object "Banana". These two objects have an N:M relationship. What I am doing is listing All of the Banana objects that are associated with a single Apple, then below that listing all of the Banana objects not associated with that same Apple. The user is then allowed to change the

I can''t think of a good reason, other than it''s legacy code which hasn''t gotten around to being changed to RoR. http://rubyonrails.org/?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 http://37signals.com/?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 http://basecamphq.com/?=PHPE9568F36-D428-11d2-A769-00AA001ACF42 http://backpackit.com/?=PHPE9568F36-D428-11d2-A769-00AA001ACF42

Hi, Noob here. One problem faced by developers of active content is making sure that the final results of their magic result in URL''s that Google and other search engines are comfortable with. Otherwise, your content won''t ever get spydered and indexed and ultimately returned in a google user''s results pages. In reading the agile rails book, it seems that the

I''m using Ajax.Updater to update a select element, and have just discovered that IE doesn''t like having its innerHTML set. I figure instead of a bunch of option tags I can return JSON and parse it to add the options, but I''m not quite sure of the best way to do this.... or any way to do it really :) Could someone point this out to me? Or am I using a totally antiquated

I need to check if a parameter is set so that I can build some information for my application, but No matter how I format my if statement in the file " Application.rb" it return the following error. You have a nil object when you didn''t expect it! You might have expected an instance of Array. The error occurred while evaluating nil.[] Here is the line if params[:day] So we

How can I capture the IP address of a user who is posting my sign-in or login forms? I want to store it as part of my user information so that if I want to block the user in the future, I can also block the IP address they used to sign in. thanks, jp -- Posted via http://www.ruby-forum.com/.

This is a very basic question but I cannot find the ''right'' answer. What is the best way to traverse an object / array with ROR. I need to look at the structure of some of the objects/ arrays but not sure how to go about it. I appreciate your assistance. Thanks Frank --------------------------------- Relax. Yahoo!
