I have just migrated from a very early version of phpwiki to the very
latest.
I have got the wiki up and working but a soon as I try and edit the main
page I get the following error:
Fatal Error:
lib/WikiDB/backend/PearDB.php:1061 Error[256]:
WikiDB_backend_PearDB_pgsql: fatal database error
* DB Error: constraint violation
* (DELETE FROM version WHERE id=98 AND version=1 [nativecode=ERROR:
update or delete on table "version" violates foreign key constraint
"recent_id_fkey1" on table "recent"
* DETAIL: Key (id,version)=(98,1) is still referenced from table
"recent".])
Here is the database setup for each of the tables:
phpwiki=# \d recent
Table "public.recent"
Column | Type | Modifiers
---------------+---------+-----------
id | integer |
latestversion | integer |
latestmajor | integer |
latestminor | integer |
Indexes:
"recent_id_idx" UNIQUE, btree (id)
"recent_lv_idx" btree (latestversion)
Check constraints:
"recent_check" CHECK (latestminor >= latestmajor)
Foreign-key constraints:
"recent_id_fkey" FOREIGN KEY (id) REFERENCES page(id)
"recent_id_fkey1" FOREIGN KEY (id, latestversion) REFERENCES
version(id, version)
phpwiki=#
phpwiki=# \d page
Table "public.page"
Column | Type |
Modifiers
-------------+------------------------+---------------------------------------------------
id | integer | not null default
nextval('page_id_seq'::regclass)
pagename | character varying(100) | not null
hits | integer | not null default 0
pagedata | text | not null default ''::text
cached_html | text | default ''::text
Indexes:
"page_pkey" PRIMARY KEY, btree (id)
"page_pagename_key" UNIQUE, btree (pagename)
Check constraints:
"page_pagename_check" CHECK (pagename::text <> ''::text)

TABLE "link" CONSTRAINT "link_linkfrom_fkey" FOREIGN KEY (linkfrom)

TABLE "nonempty" CONSTRAINT "nonempty_id_fkey" FOREIGN KEY (id)

TABLE "pagedata" CONSTRAINT "pagedata_id_fkey" FOREIGN KEY (id)

TABLE "pageperm" CONSTRAINT "pageperm_id_fkey" FOREIGN KEY (id)

TABLE "rating" CONSTRAINT "rating_rateepage_fkey" FOREIGN KEY

TABLE "recent" CONSTRAINT "recent_id_fkey" FOREIGN KEY (id)
REFERENCES page(id)
TABLE "version" CONSTRAINT "version_id_fkey" FOREIGN KEY (id)
REFERENCES page(id)
I manually went into the postgres database phpwiki and removed the entry
id 98 from table recent and was able to edit the home page. However once
saved another edit fails with the same error.
Is this a schema error or am I using an incorrect procedure?
I am using postgres on Ubuntu 10.10.
Any help would be most appreciated.
Thanks,
Pat
