Hello, I am fairly new to RoR and I have a question I hope can be solved elegantly (so many things are, so why not this one too?). I have a working solution, but I want to be sure I am doing things the "rails way" (having come from PHP). You could say I am looking for a little validation (no flames please). I have a table of units like so: CREATE TABLE `units` ( `id`

Getting this error when hitting update. NoMethodError in Article#update You have a nil object when you didn''t expect it! You might have expected an instance of ActiveRecord::Base. The error occured while evaluating nil.update_attributes Source code. def create @article = Article.new(params[:article]) @article.user = @session[''user''] if @article.save

I''m just learning Rails and have encountered a problem trying to set a field in a DB record based on the value of another form input field. Using the scaffold code, the create works as expected and the update (edit) also works.

Hello, What am I doing wrong?

Hi, I am trying to use form_remote_tag to update a record and then update the section of the page where id=''opertion_panel''. There is a javascript validation that validates the input before the record is being updated. This validation works and the record was successfully updated. The problem is after the record is being updated, it didn''t update operation_panel.

I dont know if its me or the dodgy win-32 intall of ruby/mysql, but I can''t seem to get update_attributes to work. In my user controller, I have: def update @user = User.find(@params[''user'']["id"]) if @user.update_attributes(@params["user"]) flash["success"] = "Updated Successfully" redirect_to :action =>

Hi all, I have a unique workflow where it''s making the use of validations difficult. My app is for internal use in my company and I have a funky implementation (inspired by the e-commerce Railscasts episodes) of a cart. I have products which when I "add to cart" creates an order with a state of "incomplete". The product is a line item of my order. Hope that makes

HELP! I''m a relatively new rails user and I''m stuck. I''m trying to build a relatively simple blog and I decided that I liked the way named routes look in the code.
