specomatic-db.core — org.clojars.primeteach/specomatic-db 0.0.9

The main namespace for consumers of specomatic-db. Contains functions for initialisation, retrieving and persisting entities.

by-id clj

(by-id env etype id)

(by-id env etype id fields)

Retrieves an entity by id. Returns nil if not found.

create! clj

(create! env etype entity)

Given the environment env, creates the entity of type etype in the database. Returns the given entity containing the new id and transaction id. Shape of env: {:jdbc database specification suitable for use with next.jdbc :config specomatic config :user {:id user id :permissions sequence of permissions :root? if user is root}}

default-fields clj

(default-fields schema etype)

Given schema and entity type etype, returns a seql vector of default fields.

delete! clj

(delete! env etype id)

Given the environment env, delete the entity of type etype. Returns a map of id, :tx/id, nil if not found (might be due to permissions). Shape of env: {:jdbc database specification suitable for use with next.jdbc :config specomatic config :user {:id user id :permissions sequence of permissions :root? if user is root}}

entity-history clj

(entity-history env etype id fields)

Retrieves the full history of an entity.

init! clj

(init! env)

(init! env {:keys [:skip-migration?]})

Given the environment env, does all necessary initialization. To skip automatic database schema migration, pass {:skip-migration? true} as a second argument. Currently validates the schem, initializes transaction infrastructure, ensures access control views exist and registers coercion functions.

query clj

(query env etype)

(query env etype fields)

(query env etype fields conditions)

Given the environment env, retrieves the seql fields from the etype entities matching the HoneySQL conditions. Optionally, the root entity may contain verbs like :verb/read, :verb/update as fields in addition to seql fields. These contain a boolean indicating whether or not the user (given by [:user :id] in env) is allowed to do what the verb describes with the specific entity. Shape of env: {:jdbc database specification suitable for use with next.jdbc :config specomatic config :user {:id user id :permissions sequence of permissions :root? if user is root}}

save! clj

(save! env etype entity)

Given the environment env, saves the entity of type etype into the database. Tries to create the entity if its id field is nonexistent or nil. Tries to update the entity if it has an id. Returns the given entity containing the new id (if created) and transaction id. Shape of env: {:jdbc database specification suitable for use with next.jdbc :config specomatic config :user {:id user id :permissions sequence of permissions :root? if user is root}}

save-related! clj multimethod

Saves the changeset value for related entities contained in a relational field of a entity to the database. opts is a map of outer-etype and outer-id. If :specomatic.core/delete is true in the related entity, it is deleted. Otherwise, if the id field of the related entity is not nil, it is updated, if the id field is not present or nil, it is created. In the case of a reference collection of a has-many-through type, these mutations are applied to the join table, not the actual related entity.

update! clj

(update! env etype entity)

Given the environment env, updates the entity of type etype in the database. Returns the given entity containing the transaction id. Shape of env: {:jdbc database specification suitable for use with next.jdbc :config specomatic config :user {:id user id :permissions sequence of permissions :root? if user is root}}
