[Qgis-user] plug-ins

[Chang, Elizabeth]

I was running 1.0 but I just switched to 0.11 and had some luck with New
Layer plug-in after installing psycopg version 1. Thanks for the tip.

It installed successfully but when I tried to connect to my database, I
got an error, I think, due to PostGIS being on a Linux server, not my
machine.

Is the server running on host "???" and accepting
TCP/IP connections on port 5432?

For the PostGPS plugin that needs psycopg2, is the psycopg and psycopg2
module version 1, and version 2, respectively? When I downloaded psycopg
v. 2.0.8 from the stickpeople site, I didn't see any modules called
psycopg2. There were some files called psycopg1.p* under a directory
called psychopg2. 

Thanks so much for your help.

Hi,

what versions are you running?

I'm running here on winXP, qgis 0.11 (metis). You should not try out 
python plugins in 1.0 preview yet because the api is still moving on, 
thereby making some plugins look buggy (while they were working a few 
svn-versions ago ;-) ).

Anyway,

On 0.11/XP I am able to install PostGPS fine, it doesn't look to have 
dependecies here... Mmm, nope it needs psycopg2, and apparently it's 
installed in my python. But you can find it here:
http://www.stickpeople.com/projects/python/win-psycopg/#Version1

NewLayer has indeed a psycopg dependency. For windows you can find 
packages here: 
http://www.stickpeople.com/projects/python/win-psycopg/#Version1
But probably you have a more current postgis version then psycopg 
handles, so maybe it's a nice starting project to 'port' it to psycopg2 
:-) (shouldn't be that much trouble, start with changing all 'psycopg' 
in 'psycopg2' in newlayer.py...).

(by the way, psycopg(2) are python packages, needed to make 
python-database connections to postgis.

Pypostgis has gdal-dependencies, but I have no experience with that on 
windows. Hopefully others have.

Good Luck,

Richard Duivenvoorde
