I want to ask a question
- Is there a way to register records at the migration stage?
is
I am creating a web application with a user management system with rails
Therefore, there is a problem that cannot be solved for the part that manages the user's place of residence.
The user registers the address at the new registration stage, but for prefectures, I would like to register it in a separate column because it may be used independently within the service.
So, I would like to take the form of selecting only 47 prefectures from the pull-down list at the time of registration, but I am worried about whether to describe all 47 prefectures on the front side or create a prefecture table.
If i leave the processing to the front side, the amount of description will increase, so I think that it is a good idea to consider future function implementation.
However, when I create a table, I'm not sure how to add records for each prefecture when deploying to a production environment.
I would like to have a method to automatically add records when migrating at the time of deployment, but I would like to know if there is such a method.
Also, I would be grateful if you could tell me how to manage prefectures in web applications in general.
