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 @history_size == 1" path of the code below works fine!) However, when using FCCs there needs to be a loop over the instance variable which "con...

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. --

...ell 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. It includes the following maxims to make original app creation easy: app_name = MySQL database name SQL_tablename = model_name model_name = controller-name Is this going to work for getting the simple structure set up? This naming convention seems easy to me and should work. I''d like feedback on this before I "make it real" for my process notes. Second question. with this convention I''m run...

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

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

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
