I found some very old threads, and blogs from other people struggling
with this, but is there a to_json plugin for Sequel?
The confusing thing is there are to_json methods in Sequel, but they
just inspect the object.
For the single-record case, ie:
class Main < Sinatra::Base
get '/users/:id.json' do |id|
@user = User[id] or halt 404
@user.to_json
end
end
I just monkey-patched a method into Sequel::Model that takes
advantage of Hash/Array.to_json:
Sequel.extension :inflector
class Sequel::Model
def to_json
{self.class.table_name.to_s.singularize => values}.to_json
end
end
For the collection case, ie:
class Main < Sinatra::Base
get '/users.json' do
@users = User.all
@users.to_json
end
end
I have this but it needs to be generalized:
{'users' => @users.collect{|r| {'user' => r.values}}}.to_json
Not sure where to put it because of the fact it's a dataset
collection.
So, (1) is there already a to_json plugin and (2) if not, input on the
above approaches? I can throw it into a plugin; seems reusable enough
and I need it anyways.
