Description

When editing repos via the API, the value of default_merge_style is ignored.

Querying the API with curl/jq before the change:

$ export GITEA_ACCESS_TOKEN=[...]
$ curl -s -H "Authorization: token $GITEA_ACCESS_TOKEN" https://try.gitea.io/api/v1/repos/7CLfteiIYWtD/test | jq .default_merge_style
"merge"

Trying to change the setting via the API:

$ curl -s -H "Authorization: token $GITEA_ACCESS_TOKEN" -X PATCH -H 'Content-Type: application/json' -d '{"default_merge_style": "rebase"}' https://try.gitea.io/api/v1/repos/7CLfteiIYWtD/test | jq .default_merge_style
"merge"

This should have returned "rebase".

After changing the default merge style through the UI:

$ curl -s -H "Authorization: token $GITEA_ACCESS_TOKEN" https://try.gitea.io/api/v1/repos/7CLfteiIYWtD/test | jq .default_merge_style
"rebase"

I'm pretty sure has the same cause as described in #19069 (comment)
