btw why is it even "klassname", should it not be with c "classname"

我认为问题出在Psych gem版本上。
你可以尝试在application.rb中添加这一行：
config.active_record.yaml_column_permitted_classes = [Symbol, Hash, Array, ActiveSupport::HashWithIndifferentAccess]
英文:
I think the issue is with Psych gem version.
You can try adding this line application.rb
config.active_record.yaml_column_permitted_classes = [Symbol, Hash, Array, ActiveSupport::HashWithIndifferentAccess]
