Noob - added a column via migration but get error on insert
Hello!
I''m very new to ruby and ruby on rails. I''m following a
tutorial found
here:
www.javapassion.com/handsonlabs/rails_activerecord/
I''m running NetBeans as an IDE, with jruby, rails and MySQL.
Here is the basic rundown of what I have done
1) Created db via Rake
2) Created table with 3 columns via Migration (user name:string
hobby:string age:integer)
3) Inserted 3 user records via Rails Console
4) Added additional column via Migration (AddEmailField email:string)
(Inside the migration rb -> "add_column :users, :email, :string"
5) This is where things go poorly, I try to add a new user with the
email but get an error. Here is what I enter via Rails Console
user = User.new(:name => "TommyJones", :hobby =>
"tennis", :age => 138,
:email => "emaila-hqliFBSW7YMS+FvcfC7Uqw@public.gmane.org")
And I get the following error:
--------------------------------------------------------------
NoMethodError: undefined method `email='' for #<User:0x751932>

-------------------------------------------------------------
Being so new to this I cannot figure out why it won''t allow me to enter
a user using all the fields? If I do the same entry without the email
information to insert it still works.
Thanks in advance!

Yes I did perform the migrations and can see the new ''email'' column in the database. I did not restart the console however. Does Rails need to be restarted to learn about changes like this?

So anytime I make a DB modification and am working via the console I need to restart it so it will become aware of the changes.

Very interesting.I believe you can also type app.reload! in the console. Also, as you go forward with Rails, you might want to consider giving jEdit a try as an IDE. It''s powerful, but much easier to work with for Rails than are "heavier" programs like NetBeans or Eclipse. See http://marnen.livejournal.com/23723.html for more info on configuring jEdit.
