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

Rails
#1

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…

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.
