TypeError: can't quote Hash when running transition table migration

[ollieh-m]

When I run rails g statesman:active_record_transition Order OrderTransition, the migration created includes t.text :metadata, default: {}. This line causes the migration to fail with the error TypeError: can't quote Hash

Changing the line to t.json :metadata, default: {} allows the migration to complete.

Seems the migration generator shouldn't be defaulting the column to type text.

Rails 5.1.5
Statesman 3.4.1

I have a suspicion that this might be adapted for how an older versions of Rails works. I’ll check when I get a chance!

I saw the same issue here. Fixed it locally by quoting the empty hash:
t.text :metadata, default: "{}"

I'm on MySQL here, so we cannot opt for the json column type.

@ollieh-m same here, using @ewlarson s fixx since with json i'm getting the following
Transition#metadata column type cannot be json and serialized simultaneously. If you are using a json column type, it is not necessary to include Statesman::Adapters::ActiveRecordTransition
