I''m trying to update records in a table based on data I get back from a form. In the simplest case, the params structure returned from the form is: {"illness"=>{"1"=>{"illness_date"=>"", "qualifier"=>""}}} The controller code works (i.e., updates the first record) when I do the following: params[:illness].each do

Hi Everyone, I''m a newbie to Rails, and I just finished going through the cookbook tutorial. I''m now trying to build my own application, and I''m trying to add more inputs to the edit view to modify data in other tables. Below is the controller code where I am having trouble. PartsLocation is another table (like Part) in the database, and that is the line where

Greetings! What is up with the syntax of this thing? I mean, if the only thing I can send back using :with is the field being observed, then why in the world is the syntax so convoluted? For example, what I''ve been able to get working is: <%= text_field_tag(''date'', illness_date, :size => 30) %></p> <%= observe_field(''date'', :url

Please let me know if this is or is not the right place to ask these types of questions. Warning: I am new to R by two days. I have a simple dataset. I have loaded the dataset successfully using the following code: Filepath=(C:\temp\\pilot\dataset1.txt") Pilot=read.table(filepath, header=TRUE) Dataset1.txt is delimited and looks like this: Date illness count 2006/01/01 derm 17 2006/01/01

I''m using backgroundrb for session management and deletion of visitor-entered information when a session is abandoned. The visitor can either click a button to end their session and remove their data, or backgroundrb will do it for them after 5 minutes of inactivity. Everything''s working fine, I think. If the visitor explicitly logs out, then when the worker checks for their

Hi, I''ve just been pleasantly surprised, again, by how much Rails does for me, but I am *really* surprised. Surprised as in "how the heck did that happen?" I''d really like to understand this and would appreciate any help. Big picture... the user is presented with a form that allows them to select one or more check boxes to record their allergies. The form uses the

Hi guru''s out there, Im happilly coding my first rails app, and all goes well. I find myself manually coding in a particular field all the time (company_id), that relates the contact to a company.

Sorry to be such a bother but I''m not getting this. I have two models: Emrec and Session (I''m using AR for session mgmt.) In my worker I can access the Emrec model and delete a record, AS LONG AS I don''t try to access the Session model. With the Session model access commented out as below, the Emrec record gets deleted. If I uncomment those lines, the Emrec

I''m using render to display a collection of partials, where each partial is a table row. Is it possible to zebra-stripe the table using this method i.e. alternate table rows get a different CSS class? I can''t work out how each row partial would know whether it was odd or even. In the normal scheme of things I could do: <% odd_or_even = 0 for asset in @assets

Hi, I had ferret working wonderfully but i am regretting doing a gem update today. I had alot of trouble first installing it and was really happy to have it working. The upgrade was from 0.3.1 to 0.4.0.

Has the problem with corrupted .rhtmls (invalid characters) been solved so far? I would like to use ferret and acts_as_ferret on Windows XP.

I''m a newbie to rails, and really to the whole DRY and MVC thing as well, except where I accidentally fell into things doing it my own way in the past. I''ve got a fairly complex DB structure I want to create an interface for using Rails. Getting simple tables to display, edit, save, not too much problem there. But where I''m having trouble is figuring out where to
