Restarting Terminal when creating new attribute in atom question

Rails
1

Hi All,

I just started the UT on Rails class through reddit and am completely
new
to programing. I apologize for not being able to articulate my problem
clearly. I am watching this
video Databases & Rails: Database Backed models with ActiveRecord - YouTube and at 16:18 when the
instructor restarts something (terminal) I get completely lost. He
consules back into rails after this restart but when I do this I get
this:

"User.last.cars

User Load (0.4ms) SELECT “users”. FROM “users” ORDER BY
“users”.“id” DESC LIMIT 1*

NoMethodError: undefined method `cars’ for #<User:0x00…"

I apologize again for the poorly asked question but I am really new with
all of this.

Thanks so much!

Happy labor day!

Have you followed his steps and changed your model? In other words, have
you added the line has_many :cars in app/models/user.rb?

Hi Nobert,

Thanks for responding to my question. I have completely followed his
steps
until the restart part. I did notice that when the instructor adds
attributes such as :condition and :year that they automatically appear
in
sublime, but when I check my work in atom the attr_accessible does not
appear. Could this be the issue?

Thanks again for responding!

Thanks for replying Colin. I added the “has_many: cars” line in
app/models/user.rb just like the instructor. With the attr_accessible
part, everything is exactly as it is in the tutorial. I have gone
through
the project serval times to insure that I am doing everything right and
get
the same issues every time.

Thanks again for replying!

I added the “has_many: cars” line in app/models/user.rb just like the
instructor.

Typo or copied? It has to be has_many :cars instead of has_many: cars!

If it is just a typo, please show us your complete db/schema.rb and
app/models/{user,car}.rb

There is the problem then, it should be has_many :cars, not has_many:
cars. If you think that is what you have got then copy/paste user.rb
here.

You did not answer the question as to whether you have added the line
has_many :cars in app/models/user.rb?
As to the issue with attr_accessible, you have to make sure that your
code is the same as the one in the tutorial.
