Thanks. In case anyone else is looking for a quick way to skim the data, this works in the Rails console:
results = Post.all.reject { |p| p.custom_fields['notice_type'].nil? }
results.each do |r|
puts r.custom_fields
end
Sample output:
{"notice_type"=>"returning_user", "notice_args"=>"2018-08-04T07:43:52Z"}
{"notice_type"=>"new_user"}
{"notice_type"=>"new_user"}
{"notice_type"=>"new_user"}
{"notice_type"=>"returning_user", "notice_args"=>"2016-10-11T09:32:30Z"}
{"notice_type"=>"returning_user", "notice_args"=>"2014-04-02T16:16:04Z"}
{"notice_type"=>"new_user"}
{"notice_type"=>"new_user"}
I don’t see any custom text there, so I guess the staff notice I was looking for isn’t live.
