What is the type of the field you wish to add? If it is a string do it like below:

rails generate migration add_field_to_products field:string

Where 'field' is the name of the field you want to add, so rename accordingly.

Then do in the command line rake db:migrate and after that the field should be in the model.

Also, this question is a duplicate of: Adding a column to an existing table in a Rails migration . There is more discussion of this there if it's still unclear.

You should generate a separate migration with rails g migration [name], where you declare your column:

add_column :products, :[column_name], :[datatype]

Where [column_name] is the name of the column you want to add and [datatype] stands for it's datatype: string, integer and etc.
After that you should run migration with rake db:migrate to add new column to your table.
