## Configuring plugins¶

I wondered why a Lino Welfare did not collect the raw data read by lino.modlib.beid, despite the fact that I had configured a data_collector_dir. The relevant settings.py file was:

class Site(Site):
...
SITE = Site(globals())
configure_plugin('beid',
data_collector_dir=join(SITE.project_dir, 'beid_collect'))


Explanation: Once the Site had been initialized, lino.core.site.configure_plugin() silently ignored everything. Correct code must be:

class Site(Site):
...
SITE = Site(globals())
SITE.plugins.beid.configure(
data_collector_dir=join(SITE.project_dir, 'beid_collect'))


This pitfall was known and even documented. I nevertheless stepped into it. Tried once more to protect future system administrators from it by writing that lino.core.site.configure_plugin() raises ImproperlyConfigured when called after the lino.core.site.Site instantiation. But sorry, that’s not easy because there are scenarios where you want to instantiate several Site objects.

## Finally a checkin¶

Finally a checkin with the most important projects having their test suites pass after the changes of the last days (most time-consuling troubles were for adapting welfare to the permissions system).
