I get an error when I run http://localhost:3000/login/login I get this error message=

NoMethodError in Login#index

Showing login/index.html.erb where line #3 raised:

You have a nil object when you didn’t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each

Extracted source (around line #3):

1:

5: <= image_tag(product.image_url) >
6:

Thanks Sam but I am still getting the same error message. I have given the error message again and the text from the file. I am loving Ruby and Rails. Thanks for writing the books and help us noobs out.

C:\rails\work\depot>rake db:migrate

I have a problem when I run “rake db:migrate” after I have created and editied the models “order” and “line_item” on page 140 of Check out. I get:

C:\rails\work\depot>rake db:migrate
(in C:/rails/work/depot)
5 CreateOrders: migrating ================================================
—create_table(:orders) -> 0.0780s
5 CreateOrders: migrated (0.0780s) =======================================

6 CreateLineItems: migrating =============================================
—create_table(:line_items)
rake aborted!
SQLite3::SQLException: table line_items already exists: CREATE TABLE line_items
(“id” INTEGER PRIMARY KEY AUTOINCREMENT NOT NULL, “product_id” integer NOT NULL, “order_id” integer NOT NULL, “quantity” integer NOT NULL, “total_price” decimal
(8,2) NOT NULL, “created_at” datetime DEFAULT NULL, “updated_at” datetime DEFAUL
T NULL)

(See full trace by running task with—trace)

Thanks for the help.
