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 used generate/scaffold to create simple CRUD screen that works perfectly with Webrick. I wanted to attempt to run the same ROR app on Apache. I followed the instructions found at http://wiki.rubyonrails.org/rails/pages/Fast+CGI+and+Apache2+for+Windows+XP with the alternate ending found at http://wiki.rubyonrails.org/rails/pages/Fast+CGI+and+Apache2+for+Windows+wit hout+VirtualHosts. I have

Fellow Railers, Is there anything, anywhere, that I can read that discusses overall RoR app design? I have the Agile RoR book, which is great for learning the details of RoR, but unfortunately doesn''t cover the overall issue of creating a large, complex RoR app. My staff and I are still in the process of getting up to speed on Ruby and RoR, but we also need to begin thinking about

For edge rails there is a Crud generator. There is also a CRUD controller that is out there from which you can inherit your other controllers (see http://geekonomics.blogspot.com/2006/07/crud-and- shared-controllers.html) This got me thinking about Crud controllers in general. As far as I know, the generator can''t produce crud classes which are nested (i.e.

Hi, I am new to ROR. I have created a form with foru fields in ROR. Now its working fine for all CRUD operations. But I want to validate data on form for "validates_presence_of" validation. How to do this? I tried it by putting line "validates_presence_of :description" . But its not working. Its throws error like "undefined method `each'' for

Hi All, I'm hoping someone else can help me out with this. I am doing some matrix algebra using sub-parts of matrices, and sometimes I need only a single row/column of the original matrix. However, whenever I pull out only a single row/column, R returns a row vector, but often this will break my matrix algebra. Is there any *easy* way to get R to remember what the single row/column came out

Hi all, I am looking for some time tracking software for our small company. Does anyone knows if such project on rails exists? I need simple functionality such as recording spent time for employees and managing projects or tasks. Ideally, it would be possible to integrate it into Instiki and to some existing database. There are some other solutions, but it seems to me that RoR would be ideal

I''m writing a controller which should only be inherited from, something like the generic crud controller seen here: http:// geekonomics.blogspot.com/2006/07/crud-and-shared-controllers.html Now, in my spec, I would like to create a controller which inherits from the generic CRUDController, without actually creating the controller. This controller is *only* for testing. How can I

I''ve got a database with several tables. I''d like to create scaffolding for separate CRUD interfaces for several of these tables. I''m hoping that the scaffold generator can create the CRUD code for all these tables in ONE controller, but I don''t know how to tell it to do that, if it can. Can anyone verify if this is possible? Thanks, David -- Posted via

I''ve been experimenting with Rails over the past couple of days and have come across something that seems harder than it should be. In previous frameworks I have used (WebObjects, php) a full search page (which leads into a list view populated with search results) was part of the CRUD that was either dynamically or statically created after specifying table/object schema. In

Hi everyone, I''m sure I''m doing something stupid with this, so if somebody could talk some sense into me that would be great :) I''m trying to just increment a variable and I think I''m missing some basic concept (this is RoR 2.0.2 btw) So have a "players" table with several variables, including one called "odds". I''m using the

I''m going to take another stab at this question (my first one received no replies): I have two models: Author has_many: books Book has_one: author I have two tables: authors id ... books id author_id ... I let the scaffolding fly and it created the CRUD goodness for each model, as expected. However, I want to have only one view/controller "set" for both models; when I

Hey guys, I''m trying out the new RESTful bits in Edge Rails, and am having a bit of trouble wrapping my brain around certain things. For instance, say I have a page that is separated into sections with tabs at the top. I want to replace divs on the page with RJS. Now typically before I''d have a method on the controller that rendered an RJS template to accomplish this.

Hi, I''m new with RoR. I''m trying to do a master-detail CRUD form, using generate scaffold. The problem I''m facing is that I have to keep the parent id through the detail view all the time by hand. Is there any example or way to see how to do it properly? Thanks. Fernando. PS: For further information, I have a Task and the Tasks have Items, so when I want to add an

Hello All, I am using virDomainSetBlockIoTune() API to set the IO tune parameter for a running guest VM.

Hi, I have a people controller, and want to import bulk import multiple people from a CSV file. In my routes.rb file I have: map.resource :person Now, it''s a little unclear to me how to further configure the routes to allow me to add the following URLs: I need a URL to choose a file to upload, so I need an HTML ''frontend'' for it, so I figured the following URL

I have converted my engine from myISAM to InnoDB, the matter now in Test Unit, the table cant do any changes for CRUD. Any advice?

Hi All, I just created a new CRUD "expense" (using Rails 2.3.5 scaffold) which included "amount:decimal". When I: 1. populated the amount field of a new expense with 5 characters: 12.50 and 2. saved the new record I got a display of the new record that showed Amount to be merely "12". I clicked Update and put my cursor over the data field for Amount and got a

Good afternoon. I have two questions: First question: Can be defined at the time that I''m generating the scaffold the size of a string? For example name:string (50)? Second question: I wonder how to proceed correctly to include new fields starting at a CRUD generated by scaffold. Example: First step (I use): script/generate scaffold User name:string login:string Second step (I add
