I am very new to Plone product development so please forgive this simple
question but it is something I cannot figure out. I have a simple
Archetypes based product. In one class, I have a field that defines the
type of external database (MySQL, etc.). Now in a different class
definition, I need to get this database parameter. The following lines of
code work within a class definition:
settings = getToolByName(self, 'app_settings').settings
database = settings.getExternalDatabase()
as the local variable database now contains the stored value for the
external database. However, here is my problem. I need to set the
Archetype storage parameter with this value but I cannot use this code to do
this because self is not defined before the class is defined. The following
does not work.
settings = getToolByName(self, 'app_settings').settings
database = settings.getExternalDatabase()
mystorage=database
schema = BaseSchema.copy() + Schema((
TextField('InstrumentDescription',
widget=TextAreaWidget(
label='Instrument description',
label_msgid='label_instrument_description',
i18n_domain=I18N_DOMAIN,
),
storage = mystorage,
),
...
class Instrument(BaseContent):
So my question: How do I get the value stored in the database field in the
settings class so I can use it in the schema definition for another class?
Thank you for you time.
