Where to configure languages for iQvoc (labels and interface language)?

[EwaSniegowskaPCSS]

Hi, I'm trying to configure iQvoc to use other than predefined languages.

I tried to alter the code. I put:

Iqvoc.config['languages.pref_labeling'] = ['pl', 'en', 'uk']
Iqvoc.config['languages.further_labelings.Labeling::SKOS::AltLabel'] = ['pl', 'en', 'uk']
Iqvoc.config['languages.notes'] = ['pl', 'en', 'uk']

at the end of config/initializers/iqvoc.rb file.

I try to run application then but I get an error during bundle exec rake db:migrate

rake aborted!
ActiveRecord::StatementInvalid: PG::UndefinedTable: ERROR:  relation "configuration_settings" does not exist
LINE 8:                WHERE a.attrelid = '"configuration_settings"'...
                                          ^

Without my code alterations the migration is successful.
I'm not sure where should I put this configuration code.

If the language configuration is indeed stored in a table,
maybe I could alter it using db/seeds.rb file? This would be easier
for me as I expect different deployments of the application with different
language preferences and it would be nice not to have to build a separate
docker image for each of them, just override the seeds file before migration.

I thought that maybe analysing/altering the content of "configuration_settings" table might be helpful, but it's empty for an application with default labels (en/de).

Hi @EwaSniegowskaPCSS, thanks for your interest in iQvoc.

Via app ui

You do not need to put your language configuration into an initializer. You can change configuration during runtime at /en/config.html

After saving you're able to add labels in configured languages:

via rails initlializer

Put this into an initializers (e.g. config/initializers/iqvoc.rb)

Iqvoc.config do |config|
  config.register_settings({ 
    'available_languages' => ['pl', 'en', 'uk'],
    'languages.pref_labeling' => ['pl', 'en', 'uk'],
    'languages.notes' => ['pl', 'en', 'uk']
  })
end

Please make sure that you provide a localisation file if you set a custom language (see config/locales/ for supported languages)

Thank you very much for the answer,
unfortunately I could only test it now.
Everything works as expected.

I also added the fragment:
'languages.further_labelings.Labeling::SKOS::AltLabel' => ['fr'],

to configure Alternative labels.

I have a question regarding an option Secondary in the Language menu.
I read about it in the release notes:

It's also possible to translate secondary concept relations by switching the secondary language.

But I don't fully understand it. Would it be possible for you
to provide a screenshot that illustrates this feature?
