Ruby on Rails

has_many :children, class_name:  name,
        foreign_key: configuration[:foreign_key],
        order:       configuration[:order],
        dependent:   configuration[:dependent],
        inverse_of:  :parent

If you do: root.children.where(:type => yourtype) it should just work.

Hello Experts,

I have a tree of categories in this category object there is a property

called type.

the root categories have no type but the children have. so how I can get

all the roots with filled in children that have category type = 'B' for

instance.

I tried to run Category.roots then delete children With a category not

equal to 'B' but this causes a major performance problems.

how to call roots with filter children?

best regards

Ibrahim
