== MakeWikiPageContextNotNull: migrating =====================================
-- change_column_null(:wiki_pages, :context_type, false)
rake aborted!
StandardError: An error has occurred, this and all later migrations canceled:
PG::NotNullViolation: ERROR: column "context_type" contains null values
: ALTER TABLE "wiki_pages" ALTER "context_type" SET NOT NULL
I'm trying to perform an in-place update of canvas and I'm running into a problem where the context_type field for every row in the wiki_pages table is null, which causes the data migration to fail.
I can see that there is a class /lib/data_fixup/populate_context_on_wiki_pages.rb that should populate context_id and context_type, but it isn't quite obvious to me how to determine and manually correct values context_id and context_type on the wiki_pages table.
