Here I Just started to learn Ruby on Rails! My issues is when reading
the data using my controller pages.
I initiate my controller using this command
rails g controller schoolTypes
I then initiate my model has the following command
rails g model schoolType
Once this is done i then modify has follow the following pages
create_school_type
class CreateSchoolTypes < ActiveRecord::Migration
def change
create_table :school_types do |t|
t.integer :schoolTypeID
t.string :name
t.description :text
t.timestamps
end
end
end
did a rake db:migrate
Change the following page
school_types_controller.rb
class SchoolTypesController < ApplicationController
def index
@schoolTypes = schooltype.all
end
def show
end
def new
end
def create
end
def update
end
def destroy
end
def edit
end
end
index.html.erb
<h1>School Types</h1>
<% @schoolTypes.each do |schoolType|%>
<%= schoolTypes.name %>
<% end %>
If I go to the following page http://localhost:3000/school_types I get
the following errors
undefined local variable or method `schooltype'' for
#<SchoolTypesController:0xa9cd600>
Any reason why?

your model should call ''SchoolType'' and it''s in file app/models/school_type.rb then you should use @types = SchoolType.all (case sensitive) tom On Jul 9, 2012, at 21:13 , Jean-Sébastien D. wrote:> Here I Just started to learn Ruby on Rails!

Also life will be simpler if you stick to the rails conventions for naming things (don''t use camelCase), if you needed a school type id it should be called school_type_id. I suggest you work right through some tutorials on RoR in order to get the basic principles. railstutorial.org is good and is free to use online (how many times have I typed that in the last year I wonder, my fingers type it without conscious brain involvement). Also have a look at the Rails Guides, starting with Getting Started, obviously. Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Rails uses four naming conventions for throughout it''s code which need
to
be followed by the developer (you) for their code to fit with Rails. These
involve selective use or* singular* and *plural *together with *camelize*and
*underscore*.
The simplest way to demonstrate the conventional use is to run:
*rails generate scaffold your_new_object name:string
description:text size:integer*
Then look at the model/view/controller files for uses of the variants on *
your_new_object
your_new_object
your_new_objects
YourNewObject
YourNewObjects
*If you''re running on a unix system (any Linux or OSX) this command
will
find them all when run within your application directory:
*find . -name \*.rb -exec grep your_new {} \; -a -exec grep YourNew
{} \; -a -print*
