At Chapter 3:

Line 6 sets the value for the reference field, which is not part of the input form >because it is not in the list of fields specified above.
Line 7 creates an insert form SQLFORM for the db.post table using only the specified >fields.
At first there is an issue with the numbering of code lines.
Second, the phrases 'fields specified above' and 'only the specified fields' I think must be left overs from previous obsolete versions. I guess these lines should be re-written.

The issue can be closed, as the current text is
Line 6 defines a format string for the table. It determines how a record should be represented as a string. Notice that the format argument can also be a function that takes a record and returns a string.

and text about line 7 was removed. Instead it has:

Lines 8-12 define another table called "post". A post has an "author", an "email" (we intend to store the email address of the author of the post), a "body" of type "text" (we intend to use it to store the actual comment posted by the author), and an "image_id" field of type reference that points to db.image via the "id" field.
