Delay the initialization of resource columns until needed #38

Closed marcelmorgan closed 6 years ago

marcelmorgan commented 10 years ago

At the point of initialization, when running migrations and the table did not exist for the resource class at that point, it would fail with the following error:

ActiveRecord::StatementInvalid: <database-adapter>::UndefinedTable: ERROR:  relation
"<table-name-for-model>" does not exist

The inspiration for this fix came from https://github.com/randym/activeadmin-axlsx/pull/35
