Hi,
thanks for your tip. I checked the user-dox and googled a lot, but the only
thread that got me a bit further is this one:
http://old.nabble.com/postgresql-postgis-views-and-primary-keys-td28616028.html
http://old.nabble.com/postgresql-postgis-views-and-primary-keys-td28616028.html
. However, I'm still having the same problem - hopefully you can give me
more information about PostGIS/view/primary key...
Here is what I did:
I created a table "gt_pk_metadata_table" exactly as described in this post:
CREATE TABLE gt_pk_metadata_table (table_schema varchar(255), table_name
varchar(255),
pk_column varchar(255), pk_column_idx integer,
pk_policy varchar(255),
pk_sequence varchar(255));
Then I inserted a line - to be honest, I wasn't sure, how to fill it
exactly:
INSERT INTO gt_pk_metadata_table
(table_schema, table_name, pk_column, pk_column_idx,
pk_policy)
VALUES ('public', 'species_in_ps',
'map_species_ps.map_species_ps_pkey', null, 'assigned');
* "species_in_ps" is the name of my view
* "'map_species_ps.map_species_ps_pkey" is a primary key on one of the
tables used in the view (I tried "map_species_ps_pkey" as well)
* I tried all possible values for "pk_policy": "assigned", "sequence",
"autogenerated"
Then I entered the following lines into my mapping-file
("SpeciesInclude.xml"):
<Parameter>
<name>Primary key metadata table</name>
<value>public.gt_pk_metadata_table</value>
</Parameter>
Upon start-up of GeoServer, I get the following 2 errors:
WARN [geotools.jdbc] - Unknown column map_species_ps.map_species_ps_pkey in
table species_in_ps
WARN [geotools.jdbc] - No primary key or unique index found for
species_in_ps.
And, of course, retrieving the data via WFS doesn't work. I then tried to
add the PK "map_species_ps_pkey" to "species_in_ps"-view, but PostGIS won't
have it.
A short description of the tables/views I'm using:
view "species_in_ps"
--------------------
CREATE OR REPLACE VIEW species_in_ps AS
SELECT map_species_ps.id_species, map_species_ps.id_ps, species.title,
species.href
FROM species
JOIN map_species_ps ON species.idstr::text =
map_species_ps.id_species::text;
It comprises the following tables:
table "species"
--------------
CREATE TABLE species
(
idstr character varying(20) NOT NULL,
title character varying(50),
href character varying(50),
CONSTRAINT species_pkey PRIMARY KEY (idstr)
)
WITH (
OIDS=FALSE
);
table "map_species_ps"
----------------------
CREATE TABLE map_species_ps
(
id_species character varying(20) NOT NULL,
id_ps character varying(20) NOT NULL,
CONSTRAINT map_species_ps_pkey PRIMARY KEY (id_species, id_ps)
)
WITH (
OIDS=FALSE
);
GeoServer features:
* a complex feature named "protected_sites_1_xml" chains to the
non-feature-type "speciesIncluded" (with Feature Chaining).
* "speciesIncluded" is based upon the view "species_in_ps". It does not
contain any geographical information. I have added "Primary key metadata
table" in its mapping file (as described above).
Could you pls. help me as to how to fill the entry in
"gt_pk_metadata_table"? Also: is it necessary to add the
"species_in_ps"-view in PostGIS-"geometry_columns"? I found a post that
suggested this. But since the feature "speciesIncluded" does not contain any
geometrical information, I thought that this would not be necessary?
Actually, I did add it once, but it didn't make any difference...
Thank you again in advance!
