Large texts are actually fine as long as they're kind of static.
For dynamic long texts I store them in a JSON field where I have a dict
with a key for each language I want to support, I actually made a plugin
which gives you a nice widget for this field json field which you can put
in your modules folder and import it. I'll annex it.
Example usage:
from plugin_json_translation import TranslateWidget
def represent_lang(v, row):
if v is None:
return v
if T.accepted_language[:2] in v:
return v[LANG]
else:
return v['en']
db.define_table('my_test',
Field('body', 'json', widget=TranslateWidget().widget, requires=
IS_EMPTY_OR(IS_JSON()), represent=represent_lang),
)
Then you just need to call render when you get my_test rows and you will
get a translated version.
