(->id model-or-id)Given a model with the id is stored at :id, or the id iteself, return the id.
E.g.: (->id 123) => 123 (->id {:id 456 :name "John"}) => 456
Given a model with the id is stored at :id, or the id iteself, return the id.
E.g.:
(->id 123) => 123
(->id {:id 456 :name "John"}) => 456(map-index values)(map-index key-fn values)Given a sequence of maps and a key function, returns a map of the values in the collection where the keys are the values retrieved by the key function.
E.g.: (index :id [{:id 1 :name "One"}]) => {1 {:id 1 :name "One"}}
Given a sequence of maps and a key function, returns a map of the
values in the collection where the keys are the values retrieved by the key function.
E.g.:
(index :id [{:id 1 :name "One"}]) => {1 {:id 1 :name "One"}}(nest collection)(nest {:keys [parent-fn] :or {parent-fn :parent-id} :as opts} collection)Given a collection of maps with recursive references, returns the same list with children assigned to their parents.
options: :id-fn - A key or fn that extracts the id from each model. Defaults to :id. :parent-fn - A key or fn that extracts the parent id from each model. Defaults to :parent-id. :decorate-child-fn - A function that receives a child and parent when the child is added to the parent :decorate-parent-fn - A function that receives each model that has children with the model as the first argument and the children as the second and returns the model.
