AJAX based data grid for Rails App? Is there any code/approach I can leverage?
Hi, I want to have a page in my Ruby on Rails application that is like a dynamic / updateable data grid. Like a matrix or spreadsheet segment (x rows, y columns) which one can click in any of the cells and make an update, which triggers some AJAX code to fire off the update, and then the responses come back and update whatever else needs updating based on this change. Does Rails support this? Is there a good plugin or sample application that does this I can look at? Perhaps a prototype project example?

Greg, Id start by looking at Rails'' in_place_editor: http://api.rubyonrails.com/classes/ActionView/Helpers/JavaScriptMacrosHelper.html#M000575 or this blog: http://rubythis.blogspot.com/2006/11/using-rails-inplaceeditor-and.html Also, to see it in practice, take a look at ActiveScaffold: http://www.activescaffold.com/ and try out their demos. They have basically what you are describing. You could either use their system, or even look at their source code to see how they did it. Either way, what you are describing is very doable. -Danimal On Apr 3, 8:46 pm, "Greg Hauptmann" <greg.hauptmann.r...-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org> wrote:> Hi, > > I want to have a page in my Ruby on Rails application that is like a dynamic > / updateable data grid.

You''ll have to use JSON (or XML) to communicate between the ExtJS components and the Rails (or whatever) backend. Although it doesn''t provide an editable grid, the Ext Scaffold Generator plugin does have some nifty features you can base your code on: http://inside.glnetworks.de/2008/01/18/announcing-ext-scaffold-generator-plugin-for-rails/ Best regards Peter De Berdt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Excellent - thanks guys. From a brief looks it seems ExtJS is much nicer (finishing looks excellent) than ActiveScaffold. However should I be concerned that ExtJS isn''t a Rails plugin? Would ActiveScaffold fit the Rails approach better in terms of how its AJAX prototype support is built into the controller/views *.rjs etc? Or is this really not a concern? (I''m thinking of starting to jump into ExtJS but thought I''d ask for advise first) On Fri, Apr 4, 2008 at 5:46 PM, Peter De Berdt <peter.de.berdt-LPO8gxj9N8aZIoH1IeqzKA@public.gmane.org> wrote:> > On 04 Apr 2008, at 04:46, Greg Hauptmann wrote: > > I want to have a page in my Ruby on Rails application that is like a > dynamic / updateable data grid.

(I''m thinking of starting to jump into ExtJS but thought > I''d ask for advise first)If you''re going to work with extjs, there are a couple of things you need to be aware of: - extjs is an entity in itself, it''s not part of rails and as such isn''t tightly coupled into the framework - extjs is a pretty hefty library - extjs is a javascript library, you build your interface through javascript. no javascript = no extjs - if you want extjs to follow Rails'' restful conventions for updating a record, you''ll have to manually add the _method=put parameter to the post parameters, same goes for deleting a record - you''ll have a lot more work than using something like activescaffold, but extjs does provide more flexibility - you''ll have less work than writing a full javascript component by yourself (which you could do if you find extjs not up for the job or just think you can do a better and less hefty job) - check the extjs licensing scheme if you want to use it in a commercial project Best regards Peter De Berdt --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
