Cannot unselect 'Remove source branch' when editing merge request
Summary
If merge request has 'Remove source branch' set that option cannot be removed when editing merge request
Steps to reproduce
- Edit / Create merge request with 'Remove source branch' set
- Edit merge request again, uncheck and save
- Remove source branch is still set
Possible fixes
In https://gitlab.com/gitlab-org/gitlab-ce/blob/master/app/views/shared/issuable/_form.html.haml#L145 there is only check_box_tag
. Checkbox will only send its value when it's checked and nothing if not.
Adding = hidden_field_tag 'merge_request[force_remove_source_branch]', '0'
just before check_box_tag should fix this.
Rails form.check_box will autogenerate that hidden input field but check_box_tag doesn't.
