problem after update from redmineup_tags

[rkteam]

After upgrading from redmineup_tags to this plugin, we have a problem with saved issue queries that had tags in the condition.

The problem is:
redmineup_tags use "issue_tags" for field "filters" in IssueQuery
additional_tags use "tags" for field "filters" in IssueQuery
So if you save issue query with "tags" in filters and update to additional_tags you will get error 500 on this query.
It is not big problem because you can go to /queries/query_id/edit and edit it.
But big problem if you use this query in "my page". My page totally broken and you cannot fix it without edit directly in database.

I see 2 ways to fix it:

1. create migration that edit all saved queries.
2. refactor additional_tags and change "tags" to "issue_tags" (i think it will fix Any idea how to get Additional Tags to show on RedmineUp Agile Cards #48 Tags not working with agile board #50 also)

I can do it myself but I want ask developers: which way is better?

Hi @rkteam,

would be great if you can provide a PR for your first option (migrate existing saved queries).

Note: some filters with redmineup_tags works different. E.g. multiple tags uses AND operation. This means, only renaming is not enough for a 100% migration.
