Hey all,
I'm working with a legacy database and looks like our best strategy for
managing things is going to be using Datasets and Database directly (lots
of non-trivial queries for the domain/business objects) and I'd like to do
something like `DB.fetch(big_sql_query, map_to: EntityClass) {
|entity_instance| ... }` or `DB[sql].all_mapped_to(EntityClass) # [
entity_instance, entity_instance ... ]`. Something along those lines, open
to any and all suggestions. I did some searching and didn't find exactly
what I was looking for as an existing extension or in the core Sequel
documentation.
The closest I've found in this realm (and used before) is from the
github-ds gem where you can map complex SQL to ActiveRecord instances -
https://github.com/github/github-ds/blob/312b43b3d96bb376b87bc5e05045c306f40f2623/lib/github/sql.rb#L208-L222
I'm thinking I've either missed the documentation or this is something
trivial to implement as a Sequel extension. In the end this will probably
end up being a light-weight Repository pattern build around Sequel.
thoughts?
