You need to show the code for your edit

I've got two tables in my Postgres database: categories and products.
I have a one to many relationship defined, one category can have many products.

I then created a reference and migrated the tables.
AddCategoryRefToProducts category:references
I have this in my models.
#product.rb  belongs_to :category    #category.rb  has_many :products
I've fixed the _form to include the category id. But when I edit or update the form, the category id is not written to the product table.

I think I'm missing a step somewhere, not sure where.

Any suggestions?

Thanks,
Joe
