AR-1.15.3/lib/active_record/connection_adapters/mysql_adapter.rb にこんなコメントがあるんだけど英文の意味がよーわからんです。 # MySQL misreports NOT NULL column default when none is given. # We can't detect this for columns which may have a legitimate '' # default (string, text, binary) but we can for others (integer, # datetime, boolean, and the rest). # # Test whether the column has default '', is not null, and is not # a type allowing default ''.
