Hello

I just did it.

I used this:
SELECT count(products_id) as count_products , SUM( reviews_rating ) as total FROM TABLE WHERE products_id=".$product_id;

Re: Conditions on Count or Sum in MySQL

jarnail — Fri, 28 Aug 2009 11:09:42 -0000

Can we do count and sum in single SQL?

I have a table where i need SUM of a field as will as I have to COUNT total effected rows.

Any idea?

Re: A Django Model Manager for Soft Deleting Records and How to Customize the Django Admin

That would work. If you are using a signal (pre_delete or post_delete), you might need to send it from the new function since you wouldn't want to call the real delete.

I've been doing object.deleted = 1 object.save() and not calling or overriding delete(). That way I still have the option to do the real delete in case I need it. You could probably make a real_delete() function to do that if needed though.

I think I must be missing something, as I cant see where you're setting the flag "deleted".

Would overriding the models delete function, setting delete=True and saving suffice?

Great post, thanks. I especially liked learning about StringIO as I didn't know about it before now.

Re: Python Projects in Users’ Home Directories with wsgi

I like the AddHandler approach more than what I was trying in this post. It is better since AddHandler will work in an .htaccess file. Which means this doesn't require a new public_python folder and doesn't require /p/ to be added to the url.

Before arriving at the solution in my post I tried using an .htaccess file and the directives I tried weren't supported in .htaccess. I didn't read the part about AddHandler so I missed that.

Something with either WSGIDaemonProcess or WSGIProcessGroup from the code in the blog post is making those applications work in daemon mode. It seems like any wsgi file that is touched will result in the code being reloaded for that project.

Re: A Django Model Manager for Soft Deleting Records and How to Customize the Django Admin

I tested this out with a simple many to many example and I am not getting the soft deleted objects returned. With objects = SoftDeleteManager the many to many queries will be using get_query_set() which won't return the soft deleted records. I might need to see an example of how you are getting the deleted results to be able to figure out what is going on. I tried it with some_object.related_things.all() and the returned set won't have deleted related_things.

Awesome tutorial... this has been really useful. One thing I've had an issue with is related fields (specifically with to M2M relationships).

A simplified version of my issue works kind of like this: I have a lot of models that all derive from a base content class (articles, images, galleries, etc.). Articles are able to have related content (via a many to many field), but when I soft delete content, it'll still show up in related content queries on my articles. Is there a good way to get this method working for inherited classes and/or m2m fields?

Re: Python Projects in Users’ Home Directories with wsgi

Graham Dumpleton — Sun, 12 Jul 2009 02:01:49 -0000

Sorry, I have been busy. For a start, look at latter part of section 'The Apache Alias Directive' in:

http://code.google.com/p/modwsgi/wiki/Configura...

The approach here, using AddHandler and multiviews matching, is to overlay, or insert, the WSGI application into the directories containing the static files. It results in a slighter cleaner configuration that using WSGIScriptAlias and then trying to overlay static resources on top of the WSGI application. Using AddHandler means you can add both WSGI applications and static files without needing to change Apache configuration and restart Apache.

I have ignored daemon process groups for the moment, but can still be used in conjunction with this approach.

Re: Python Projects in Users’ Home Directories with wsgi

gallard — Thu, 09 Jul 2009 11:06:15 -0000

I tried it without the LocationMatch directives and it works with just having AliasMatch in there for the static locations.

I didn't expect that WSGIDaemonProcess wouldn't expand the python_project_name. I was doing that so that each project would have a different process so touching one wsgi file wouldn't effect another project. It seemed like it was working like that.

If you can figure out a better way of doing this that would be awesome.

Re: Python Projects in Users’ Home Directories with wsgi

Graham Dumpleton — Wed, 08 Jul 2009 21:43:42 -0000

The LocationMatch would be empty at that point and serving no purpose. The Alias and AliasMatch directives will always take precedence over WSGIScriptAlias and WSGIScriptAliasMatch, thus why you don't need the SetHandler None fiddle that mod_pythoin requires.

BTW, am still looking and will post better configuration, but to start with, using:

wsgi_processes.%{ENV:python_project_name}

for argument to WSGIDaemonProcess is wrong, as that will not be expanded. Not even sure how it is working for you, as WSGIProcessGroup would be expanded and so wouldn't match the WSGIDaemonProcess and so it should give an error that you are delegating a non existent daemon process group, when request comes in and is evaluated.

gallard — Wed, 08 Jul 2009 18:26:33 -0000

Thanks for taking at look at this. I'll test it without SetHandler None when I get a chance. It is probably something I was keeping around from when I was using mod_python. I'm guessing I need to keep LocationMatch in there so that the request doesn't go to the wsgi file though, right?

Re: Python Projects in Users’ Home Directories with wsgi

Graham Dumpleton — Wed, 08 Jul 2009 17:09:37 -0000

You don't need 'SetHandler None' when using mod_wsgi. That nonsense should only be required for mod_python. I also suspect you have gone about this the hard way and there is easier ways which are documented in the mod_wsgi wiki. When I get a chance I will look through what you have done properly and comment again.

Re: A Django Model Manager for Soft Deleting Records and How to Customize the Django Admin

gallard — Thu, 02 Jul 2009 09:50:13 -0000

You can do this.
from somewhere import SoftDeleteManager

class NewManager(SoftDeleteManager):
'''new stuff'''

and in the model
objects = NewManager()

Metin — Thu, 02 Jul 2009 04:30:50 -0000

Great writeup, thanks for that! I'll have question though.
Say I import SoftDeleteManager from an external file and use it with objects = SoftDeleteManager()
But now, I loose ability to define additional custom manager methods because objecst is already assigned, right? Is there a way to solve this other than inheriting from multiple manager classes?
