1 Stopped DB Backend in the middle, here's where we left off:
5 * Started doing the migration generator in generators/db_backend.rb
6 * Translation keys will be in dotted string format
7 * Question: Do we need a plural_key column, or can we build it in to the dotted key?
8 * We will probably have to code the following methods from scratch, to optimize db calls:
12 * We should refactor @interpolation@ code so that it can be included into backend code without inheriting SimpleBackend
13 ** Rationale: interpolation is something done entirely after a string is fetched from the data store
14 ** Alternately, it could be done from within the I18n module
18 There will be two db tables.
20 # globalize_translations will have: locale, key, translation, created_at, updated_at.
21 # globalize_translations_map will have: key, translation_id.
23 globalize_translations_map will let us easily fetch entire sub-trees of namespaces.
24 However, this table may not be necessary, as it may be feasible to just use key LIKE "some.namespace.%".
28 We'll almost certainly want to implement caching in the backend. Should probably be a customized
29 implementation based on the Rails caching mechanism, to support memcached, etc.
33 We'll want to pull in lots of stuff at once and return a single translation based on some
34 quick Ruby selection. The query will look something like this:
38 SELECT * FROM globalize_translations
39 WHERE locale in (<fallbacks>) AND
40 key IN (key, default_key)
44 The Ruby code would then pick the first translation that satisfies a fallback, in fallback order.
45 Of course, the records with the supplied key would take precedence of those with the default key.
49 We should revisit the :zero plural code. On the one hand it's certainly useful for
50 many apps in many languages. On the other hand it's not mentioned in CLDR, and not a real
51 concept in language pluralization. Right now, I'm feeling it's still a good idea to keep it in.
