similar to: why scaffold.rhtml?

Apparently a scaffold creates at least one instance variable for views to use, and if I override the scaffold then I must also explicitly create that instance variable for the view. I''d like to know exactly what work is performed by the scaffold so that I can know this when over-riding the view. (OR, is it that the controller makes these variables available by default?..) EXAMPLE:

Hi all, I''m new to rails. I have created a bunch of CRUD code using scaffolds. I had to add code to the default output to account for fields that establish the relationships between tables. Everything works well, including the validation of the fields I added. However, I can''t get the highlighting to work for my fields when they fail validation and the view is redisplayed.

Hello all, I''m working on a couple of Rails projects at the moment and have noticed something that seems to go against the DRY principal. Why, when scaffolding, are individual CRUD rhtml files created instead of using one as a partial and having the others use that single partial? This especially applies to the list rhtml. I am about to get to the other operations and see how feasible

I''ve got a database with several tables. I''d like to create scaffolding for separate CRUD interfaces for several of these tables. I''m hoping that the scaffold generator can create the CRUD code for all these tables in ONE controller, but I don''t know how to tell it to do that, if it can. Can anyone verify if this is possible? Thanks, David -- Posted via

Good afternoon. I have two questions: First question: Can be defined at the time that I''m generating the scaffold the size of a string? For example name:string (50)? Second question: I wonder how to proceed correctly to include new fields starting at a CRUD generated by scaffold. Example: First step (I use): script/generate scaffold User name:string login:string Second step (I add

Hi, Have I missed there being any (extra) scaffold capability in ActionWebService (AWS)? I know about web_service_scaffold placed within a Controller class, which generates WS functionality based on the Api. But might there somewhere be a means to get AWS generation of Api and Controller code that automatically exposes all an ActiveRecord model class''s CRUD member operations as

Since I upgraded from Rails 0.13.1 to 0.14.1 "generate scaffold <Model> <Controller>" doesn''t take any notice of the controller parameter. Anyone else suffering from this? E.g.: C:\Ruby\work\test>ruby script\generate scaffold User Admin exists app/controllers/ exists app/helpers/ create app/views/users exists test/functional/

Running ruby script/generate scaffold Product Admin is a wonderful way to set up well, exactly what it says, a scaffold. My problem is that I have several other tables that are linked, through foreign keys, to the Product table. Say an "authors" table. Now when I go enter a new product, a book, I want the application to provide a drop down list of authors generated from the records in

Hi all, I have confgured my oracle application with the Oracle Express Production release database. This all is configured well and tested(I can see that he founds the database). However, when I generate a scaffold application there is no view for the CRUD functions created for the application. Below is listed what is generated for me for a Products table: E:\workdir\ruby\depot>ruby

I went through a tutorial at http://www.onlamp.com/pub/a/onlamp/2005/01/20/rails.html?page=1 to get started with RoR. I really like the idea of the scaffold construct, but I can''t seem to get it to work the way it was described in the tutorial. I''ve got a mysql database that is properly configured, and a table called ''quotes'' with a column called

i, I have this in expense_controller.rb: class ExpenseController < ApplicationController scaffold :expense end It works fine, but let''s say I want to override scaffold''s list. For some reason, just making list.rhtml in views\expense is enough, and there''s no need to add def list end in expense_controller.rb. However, that''s not my real problem. Now

Hi Everyone, I built a scaffold and I''m having trouble getting results properly formatted. (I need to get the data into multiple columns instead of just one big column) I can''t get all of my CSS to work properly in scaffold.css, layout/books.rhtml, or the books/index.rhtml.erb Anyways, maybe you have a suggestion. Default view (127.0.0.1:3000/books) Title Abstract

I''m a pretty big newbie with ROR, but when following a tutorial I encounter an ugly error when building a scaffold.

Let''s say I have the model class Reader and Magazine, connected by join model Subscription.

Hello All, I''ve been playing with Rails - did the recipe/category sample from onLamp.com - fairly straight forward - even got it working against postgres. Anyway, I''ve been appling rails to a small test project and I can''t seem to get the syntax down or find a sample of how to use the date control on a custom new/edit view. The CRUD (is that right?) that automatically

HI all, I"m using 1.1.6 script/generate scaffolding. Why does the view/foos/list.rhtml use "foo.send(column.name)" to display the contents of each column? I had to change this to "foo[column.name]" to get the display right in a couple of models. Specifically, one model has a column named ''display'', is that conflicting with something internally to AR ?

In iteration D.1 on page 109 I am not getting a styled error message box displayed at the top of the checkout as described in the tutorial and I cannot seem to discover where I have erred. The scaffold.css is copied from the pragmatic programmers site: #-------------------------------------------------------------------- $ cat public/stylesheets/scaffold.css body { background-color: #fff;

Hi: i''ve tried this on three macs (tiger, panther, etc).. and my ROR is up to date on each. My models and controllers aren''t displaying all my mysql db fields. When I run script/generate scaffold Planner ... it builds the controller, model, and all the rest. When I go to test the app and new controller, now called planners no content is listed... and all I ever get is the
