>=3B Hi=2C

>=3B first select the right category and iterate over the artic= les
>=3B afterwards.
>=3B
>=3B For example:
>=3B
= >=3B cat_id =3D 2
>=3B category =3D
>=3B case cat_id
>= =3B when 1
>=3B category1
>=3B when 2
>=3B categ= ory2
>=3B else
>=3B category3
>=3B end
>=3B cat= egory.article.each {|art| puts art.name}
>=3B
>=3B It would actu= ally be better if you'd store the different category
>=3B objects in = a structured way (like in a array). That would make selecting
>=3B th= em much easier.
