New rails user - Trying to understand why console wont run save command

Hi Everyone,

I just found this forum today and I'm having trouble with a rails tutorial I'm working on. On all other rails console commands it runs when I hit enter such as:

">> subject.new_record? => true"

However when I try to save a record using:

subject = Subject.new(:name => "First Subject", :position => 1", :visible =>

true)

Nothing happens. I tried create as well. When I hit enter it just puts an enter and doesn't run the command which returns. Any clue what I'm doing wrong?

That won't save a record. It will only create an object. To save it as a database record, you need to do subject.save -- and that also assumes that the class inherits from ActiveRecord, you've created the table in the database, etc.

Does it do absolutely nothing, not even tell you something like:

  => #<Subject:0x00000100a218a8 name="dave", position="reclining", visible=true>

? That is indeed odd. Can you post the code of the class, at least the initializer?

Subject.new only create a new object in memory, to persist in the database you should to use subject.save or directly Subject.create(:name => “First Subject”, :position => 1", :visible => true)

You've got an extra quote in there after :position...

wow. The quote was the issue. Unbelievable. Thanks. I'm back to cranking out this tutorial

The reason it did not do anything was because you had not entered a complete statement (the extra quote meant that the last stuff on the line appeared to be a quoted string) so it was waiting for you to enter the rest of the statement. I imagine it prompted you with a > or similar.
