Unable to delete issue statuses
I'm still using redmine 0.5.0 and wanted to give a try to redmine 0.6.3. I'm using PostgreSQL as the redmine database. So I did a dump of the database from one server, and imported to the test server. Configured the version 0.6.3 to use the new database, and did a
rake db:migrate RAILS_ENV="production"
Everything went ok and I started testing the new version (running with webbrick).
If I go to Administration and then Issue statuses and create a new issue status, I cannot delete the issue status I just created. I get the message "Unable to delete issue status".
Looking at the logs, i find the following:
IssueStatus Load (0.000132) SELECT * FROM issue_statuses WHERE (issue_statuses."id" = 11)
SQL (0.000047) BEGIN
Issue Load (0.000383) SELECT * FROM issues WHERE (status_id=11) LIMIT 1
Workflow Delete all (0.000195) DELETE FROM workflows WHERE (old_status_id = 11)
IssueStatus Update (0.000125) UPDATE issue_statuses SET position = (position - 1) WHERE (1 = 1 AND position > 8)
IssueStatus Update (0.000000) PGError: ERROR: null value in column "position" violates not-null constraint
: UPDATE issue_statuses SET "is_closed" = 'f', "name" = 'klklkl', "position" = NULL, "is_default" = 'f' WHERE "id" = 11
SQL (0.000052) ROLLBACK

Perhaps this only happens with PostgreSQL.

Could you try to reuse the update SQL line in a postgresql terminal, please?
UPDATE issue_statuses SET position = (position - 1) WHERE (1 = 1 AND position > 8)
I'm rather sure that the problem is (position -1) where position should be already replaced by the old position value. Trying the exact line confirm that Postgresql can't reuse a referential value during an Update command.

No, the problem is not with that statement. If you check the log above you see that the error is with the next statement:
UPDATE issue_statuses SET "is_closed" = 'f', "name" = 'klklkl', "position" = NULL, "is_default" = 'f' WHERE "id" = 11
Just to confirm that:
redmine=# UPDATE issue_statuses SET position = (position - 1) WHERE (1 = 1 AND position > 8);
redmine=# UPDATE issue_statuses SET "is_closed" = 'f', "name" = 'klklkl', "position" = NULL, "is_default" = 'f' WHERE "id" = 11;
ERROR: null value in column "position" violates not-null constraint

A bit more of info on this. The rake db:migrate command run without errors, and my schema is in the version 86 as expected:
redmine=# SELECT * from schema_info ; version --------- 86 (1 row)
So i think that migration 76 is not working properly with postgres. If we check table issue_statuses, we get:
redmine=# \d issue_statuses Table "public.issue_statuses" Column | Type | Modifiers ------------+-----------------------+------------------------------------------------------------- id | integer | not null default nextval('issue_statuses_id_seq'::regclass) name | character varying(30) | not null default ''::character varying is_closed | boolean | not null default false is_default | boolean | not null default false position | integer | not null default 1 Indexes: "issue_statuses_pkey" PRIMARY KEY, btree (id)
I have the last version of the postgres adapter and I'm running PostgreSQL 8.2.4:
postgres (0.7.9.2008.01.28, 0.7.1)
Ruby extension library providing an API to PostgreSQL
#4 Updated by Jean-Philippe Lang over 14 years ago
There was a bug on a few migrations. Some not null constraints were not removed with Postgresql.
This is fixed in r1140 and ported in 0.6 stable branch.
You can checkout the
branches/0.6-stable, but you'll have to rerun the migration from your 0.5 database copy.
I hope you will enjoy the new features :-)

- Status changed from Closed to Reopened
- Target version changed from 0.7 to 0.7.1
This still doesn't work on MySQL. I even changed the status on all issues to something other than the one I want to delete, and it still didn't work: "Unable to delete issue status".

After further investigation, it seems as though the status initially named "Closed" (the name can be changed) cannot be deleted. I swapped names with a created status, and then I could delete it. Is it really necessary that this status needs to be special (i.e. cannot be deleted)?
#10 Updated by Jean-Philippe Lang almost 14 years ago
- Status changed from Reopened to Closed
- Target version set to 0.7
There is no special behaviour for the "Closed" status.
