Dear Rubyists/Rails gurus, Though I''ve successfully completed the various Rails tutorials online and the Depot application from the Agile Web Development with Rails book, I''m still pretty much a Ruby/Rails newbie. I''m trying to learn by writing my own simple blogging application, but I''ve run into a problem that has had me scratching my head for a few days now.

Ok, totally no reason why I''m getting an error in this model update and no other. HELP! CONTROLLER: # GET /employees/1/edit def edit @employee = Employees.find(params[:id]) end VIEW: <h1>Edit Employee</h1> <div id="main-sub"> <%= error_messages_for :employees %> <% form_for(@employee) do |f| %> <table width="600"

Hey all, I know that this: Called id for nil, which would mistakenly be 4 -- if you really wanted the id of nil, use object_id means that I have an instance variable that has not been initialized. However, I''m a little confused as to what to do in a signup form for form_for: <% content_for :login do %> <% form_for @user, :url => { :action => "login" } do

I realize thi may be more complex issue than can be asnwered in this post. But, what I need to do is create a simple query on my existing tables via a search form. I have half my app done (I can write all the info I want to my database), but pulling the data out dynamically is giving me trouble. I have both the "ruby for rails" book and the Agile Development book. They both give

I messed around with Rails for a while last year, but then got busy and had to drop it. However, I now have time again, so I''m starting to play around with a simple database schema to model my extensive collection of photographic material, including equipment, negatives, photographs, etc. I''m running into an issue with using belongs_to/has_one methods.

Hello there, this is probably a very simple problem but I''m stuck. I''m following the Login generator tutorial from rubyonrails. It''s all worked fine so far. But I want to add a bit more functionality so that when a user signs up in addition to chosing a login name and password they type in a company name which is added to a seperate table called COMPANIES. The id

Hi I am new to the whole Rails/Ruby world as having come from a MS .NET background, but I have followed the Depot example in the Agile Web Dev. with Rails book with relative ease. However as an exercise to see how much I had understood, I thought I would attempt to modify the example a bit and add a Quantity field to the store index so as to pass that value into the cart. I have extended the

It seems common to use RJS for quickly adding and highlighting a list that is having content added to it like this: http://rafb.net/paste/results/Z3m32g48.html ... where "my_list" would be an UL and the partial would insert a LI. Given that example, is there an easy way to highlight only the newly inserted LI instead of the whole UL? The only way I can see to do it is to give

Hi all, Im trying to get my head around rails and to help along Im working through "four days on rails" as this seems to give a good real world example with multiple tables and relationships (the main thing I cant work out!) Ive got stuck. Some help would be really good here. The controller has this code: def list @category_pages, @categories = paginate(:category, :per_page =>

<td><p align="right">Jul/10:</td> <td><%= select_tag "jul10", "<option>Y</option><option>N</option><option>R</option>" %></td> At the moment, my html form displays this combo box the way i want it, but it does not record down what the user has selected and save it to the database help please,

I am trying to put some smarts around a call to <%= error_messages_for %> so that when I first come into this page i.e. when my instance variable @target_list has not been defined yet, the page doesn''t break. I''m doing this: <% if @target_list? %> <%= error_messages_for ''target_list'' %> <% end %> I get a syntax error on line 1.

Greetings, I''m in the throws of deploying an app on site5, and I''m getting strange errors. I think I might need to understand how error_messages_for works. I get a pretty standard looking error: " 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.errors Extracted

Hey All ! I have a form which contains two models. I would like both models to be validated, but have their validations aggregated on the page. If I do: <%= error_messages_for(:model1) %> <%= error_messages_for(:model2) %> It puts two big validation blocks on the page. I would like all the errors from both models, but only in one validation box. Is this possible ? All my attempts
