Hello! I''m a beginner of rails. I made a simple test project with rails 1.1.2 and ruby 1.8.2 on Windows XP. DB is SQLServer 7.0. I''m connecting the server thru ODBC. I created a table named "users" with about 10 columns. I inserted 1000 sample records. I created a scaffold for user model and login controller for it using the script. Everything''s fine

Hello, maybe that I''m a stupid, but I don''t know how I can working with pagination. In all examples is written (for example) next: def user_list @user_pages, @users = paginate(:users, :order_by => ''name'') end So, it''s OK (as a scaffold) for all set of users. But I need a little other functionality. For example I need paginate only a little bit

I want a scaffold to manager both products and users. To get the products scaffold I used script/generate scaffold Product Admin if I use, script/generate scaffold User Admin will it overwrite my product admin controller? Would I be better off doing script/generate scaffold User User_Admin or something? -- Posted via http://www.ruby-forum.com/.

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?..)

Hi everyone, I''m a rails & ruby nuby, and this is my first post to the list.

I am attempting to generate scaffolds on legacy tables that have underscores in the name. Scaffold does not see the underscore. I have tried a backslash escape but it no work. I have looked around but i cannot find a way to make it work. It''s like this: c:\railroad>ruby script/generate scaffold FOO_BAR exists app/controllers/ exists app/helpers/ create

I know the scaffold generator is really only useful for beginners and/or very the preliminary state of a project, but I find that I use it a lot (especially, since I am still a beginner). There are a couple of things I find myself tweaking (or wanting to tweak, but never getting around to tweaking) each time I generate a new scaffold: 1) Change the layout from blah.html.erb to

How do I get scaffold to generate code for a table whos name is not plural of the modelname I give to it.

I''m doing very well 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

Hello All! I''m novice at ROR. Would you like to explain what mean such constuction in Ruby. 1: class DemoController < ActionController::Base 2: scaffold :item 3: end Is 2th line calling of method ''scaffold''?

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?

I''m following along with the depot example in ''Agile Web Development'' and ran into a problem with Scaffold. I changed the MySQL table structure to add a few columns directly and also tried the migrate script to change the database after I got the initial scaffolding to work. However, I can''t seem to get the new columns to show up and am stumped as to how I can
