syntax error ruby on rails

Question

I have just started learning Ruby on Rails from pragmatic programmers 'Agile Web Development with Rails'.

I have wrote a small application and when it runs I receive the following syntax error when I run it:

/Users/colinlabri/Desktop/depot/app/models/product.rb:2: syntax error, unexpected ':',   expecting keyword_end
  attr_accessible : title, :description, :image_url, :price
                   ^
/Users/colinlabri/Desktop/depot/app/models/product.rb:2: syntax error, unexpected ',', expecting tCOLON2 or '[' or '.'
  attr_accessible : title, :description, :image_url, :price
                                        ^
 Rails.root: /Users/colinlabri/Desktop/depot

Application Trace | Framework Trace | Full Trace

app/controllers/products_controller.rb:1:in `<top (required)>'

The code for the DB is as follows:

class CreateProducts < ActiveRecord::Migration
  def change
    create_table :products do |t|
      t.string : title
      t.text :description
      t.string :image_url
      t.decimal :price, precision: 8, scale: 2

      t.timestamps
    end
  end
end

Versions are as follow: ruby 1.9.3p362 Rails 3.2.11

Should I be checking my sqlite installation and how so?

Answer 1

You just need to fix this line:

t.string : title

to:

t.string :title

Your model also has the same problem in the attr_accessible call.

Answer 2

:something are actually symbols in Ruby. You cannot leave any space between : and the symbol name.

Change t.string : title to t.string :title in the migration file.

And in your product model,

Change attr_accessible : title to attr_accessible :title
