Hiall, I have the following problem: I need to use forms containing collections (i will call them FCC), and I want to construct them dynamically, as I need to deal with quite large forms (more than 600 input fields). The variables @model_name and @field_name contain the proper model and field names as strings, which is enough for "normal" form input fields. (i.e. the "if

I am brand-new to RoR and have only followed and replicated the few tutorials that are out there. I have searched and searched, but cannot find an answer to this simple question: How can you list records in descending order? I have the cookbook example loaded, but can''t seem to list the recipes in reverse order (by the primary key - id). Thanks ahead of time for any and all help. --

I''m doing very well with the Hibbs Rolling on Rails tutorial. I have an easy question for my personal notes. I''m coming up with a simple framework of steps for creating a basic database.

Hi! I know that there are other topics about this issue, I read them and I''m always blocked.

I use file_column and it works fine. I tried to change the store_dir to a the path I want my files to be stored and not the default. I stored some images fine. But when I try to reach my images it seems like file_column uses the model_name/attribute_name on the image and not the store_dir I used. How can I change this ? Thanks in advance -- Alexander Antonakakis

Hi, I have a simple program that tries to do something really basic. First, I have a company Model : ------------------------------------- class Company < ActiveRecord::Base has_one :billingAddress, :foreign_key=>"id", :class_name=>"Address" end Then I have the address Model : -------------------------------------- class Address< ActiveRecord::Base belongs_to

I''m trying to get a collection_select generated Drop-down box to display two fields from a table (first name & last name); however, I am having trouble concatenating the symbols. It appears as though any code I put in the 5th argument for collection_select is processed prior to executing the collection_select method. The code executes successfully with 1 symbol in the 5th

Greetings: I am writing a basic accounting module for an app. Rather unfortunately the name "transactions" is a reserved term in Rails (being the only accounting term trully representational of a financial transaction). I am left to come up with other names. One such name was f_transaction. This worked on the DB level, but I noticed that the Model name dropped the underscore, thus

Hi guys, I found the troblue and fix it! I attached the patch. The trouble was in the command reply buffer use. You compute the value that value = reply[6]*256+reply[5] <- it's wrong The right solution: value = reply[5] * 256 + reply[6]; And other bug, battery.runtime compute, you divide this value 60 <- it's wrong right value: divide 1.0 I continue the work on this

Hi everyone, I''m trying to use ajax to update the selected value of a select element.

I am new to Ruby on Rails and have a very simple foreign key example that is driving me nuts. I am using Rails 3 under Windows Vista and have two tables: users and user_comments. user_comments.user_id should point to the user a comment is about. In my show view for user I have a link to the new method of user_comments to allow a comment to be created. This throws: Showing

I have an HTML form on the screen, that is connected to a database (standard Ruby way). I found that there are people that would rather not fill in this information, but would rather search Amazon for the info. Therefore, I added a link to the right of one of the fields that, when pressed, will search Amazon for what ever you typed into that field. So, how can I do that? At first I tried

Hi guys, I just started using Ruby on Rails. After implementing the RoR blog tutorial I started with my own data model. Sadly I am not able to get my create page running.

Hi, I''d like to do a "find_by_sql" without a model (e.g. <model name>.find_by_sql("...")) as the results I get back are a once off special, and I''m happy to handle them as an array. How do I do this? "ActiveRecord::Base.find_by_sql(...)" does not seem to work? Background - At the moment I''m doing within a model <model_name>,

Hello everyone! Ive been on rails for the last month or so and really enjoyed this framework. However its very hard to find documentation on how to do things right! For example every beginner after a while realizes that having similar CRUD actions in every controller and views for them is not DRY at all! Few days ago I found http://dereksivers.com/rails-shared-controller.html I quite like his

I''m working on a library similar to acts_as_taggable. I''d like it to be a simple, one file drop-in: i.e., put my_library.rb into RAILSROOT/lib/ and have everything work. However, the library requires a controller to render some stuff, so I need to be able to create the controller class, set the routing, and extend the controller at run-time from within my_library.rb. I have code
