Re: Django vs Rails
It's a personal choice. Why not take a day and evaluate the contenders by writing a simple little app (voting/wiki/blog etc.) Find which one fits with you. Also think about how and where it will be deployed/hosted and how easy/possible that is with the system you choose. Personally: having written big web apps in PHP I vowed "never again" and tried RoR, TG, Plone and DG - for me DG feels right. I wouldn't read too much into the Ajax thing - I'm doing Ajax now just fine with DJ and Prototype. Also don't assume that because it looks easy in a screencast, it will be easy when you try it. You might like to checkout this video from JPL http://oodt.jpl.nasa.gov/wiki/display/oodt/Home - Click on "Better Web App Development" - ignore the bit about DJ not supporting i18N Cheers Simon --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Problem with threads accessing MySQL database
Hi Dave, Thanks for your comment. That is an ingenious way of getting your tasks executed by views. Django is so new to me that I'm clinging to my first conception of how task timing might work lest I become completely lost :-) I'm working on a system to automate interactive TV and synchronise components with external triggers so having the ability to run threads that kick off frame-accurately is pretty mandatory. What I find amazing is how easy it is to make an application like that in python (less than 100 lines of code) and how useful Django is in providing a reconfigurable data structure and web front end.

Re: Problem with threads accessing MySQL database
Hi Eugene, Thank you for your advice - that makes sense. At the level I'm working at (first project) and given that locking the single connection doesn't kill my application (actions can still be performed in real time and the only delay is to writing logs and statuses back to the database) I'm happy with Django's capabilities. What amazes me (beyond how useful Django is to me) is how responsive people involved in the project are to uninformed queries like mine. Thank you for your time and effort.

Does that make sense?Yup. The problem here is that Django assumes that if you have a ManyToMany field on self, then the relationship is symmetrical: for example:class Person:
friend = ManyToManyField('self')If I am your friend, then presumably you are my friend. To avoid confusion, the reverse representation of the relationship (person_set, or whatever related_name specifies) is not added to instances of Person.
Obviously, there are some use cases (such as yours) where this is not the case - to handle these, you need to set symmetrical=False:
insert_into = models.ManyToManyField('self',
null=True,
blank=True,
related_name='insert'
symmetrical=False)
This will add the related_name member on the related object, and will be a distinct set; adding to PressRun.insert_into is not the same as adding to PressRun.insertHope this helps,Russ Magee %-)

Re: Using _pre_delete() to stop execution
Thanks for the quick reply, Arthur. I've gone over the MR version of doing this, by overwriting delete(), which seems to be like a good approach. I have not tried to add it to my code, because due to some bad management, I'm currently not working on that particular code. In a way, the problem fixed itself. ;-) I will probably come back to it soon, and I intend on using it. I also agree with Glenn. As a relative python newb, my first thought was "Oh, so I shouldn't raise an exception if the delete fails? Hmmm, probably because it would make the admin app do wierd things." I was actually curious if it would be appropriate to take this a step further. Have a "can_delete()" which would check if the logged in user can do some action. After all, you don't want to give a user false hope by showing them a widget which will just return an error. I realize that this may be done with group permissions, but it's just not the same amount of control. Imagine if I allowed logged in users to delete their own stuff, but not someone elses. Then, you have managers who can delete stuff that belongs to them or to one of their team members. And then you have admins who can do whatever they want. Since Django currently doesn't have "can delete self only" permissions, could I fake it with a psuedo-delete inside the Model? This would require accessing current user in the model function. Maybe this patch? http://code.djangoproject.com/attachment/ticket/1132/current_user_field_patch.2.diff These are just some random thoughts, feel free to ignore them. Thanks for the great software, I'm hoping to devote more time to it as soon as I get a chance. ;-) Norbert. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I put in the patch for the initial Django/Dojo mashup (Dojo is the JavaScript toolkit we're going to ship with Django) just the other day, and I've had a tarball of a modified Dojo-enabled Django admin app up for a while. Note, however, that this is not "AJAX integration" in the sense that Rails has it; we'll be including Dojo in Django and offering the admin app as an example of how you can take advantage of it to build useful JavaScript functionality into your own applications. There's been talk of a generic Django web-service system which would make it much easier to do remote JavaScript calls (or programmatic calls from any language, really), and when that's built in there will undoubtedly be a JavaScript library included with Django which can take advantage of it, but I don't think the extreme level of "AJAX integration" in Rails is something that would feel right in Django. > 4.

Django vs Rails
Several friends have been pushing me to look at Rails, so I've been reading through "Agile Web Development with Rails". Some quick thoughts... with a couple of questions thrown in... 1. Ok, there IS the Ruby vs Python thing... I'll leave that to some *other* place for THAT flame fest as I do NOT want that here! 2. In Rails you need to declare your SQL code *and* tell Rails about your schema, but in Django it's all very nicely put into an object oriented description in your model. A big win, to me, for Django. 3. Rails supports and integrates well with Ajax. I know that this is "coming" for Django... sometime "real soon now"... how's it going? When might it be out? 4. Rails has built-in unit and functional testing support. I don't know, but I'd venture a guess that few Rails apps actually USE the built-in testing capabilities, but it *IS* very nice... Is there anything like that planned for Django? 5. Rails has a book or two already out there -- and already out of sync with the version of Rails recently released. Django's book is "in the pipeline" but I doubt it'll be out until 0.92 gets released.

I had a similar (but a bit more complex) thing solved for me by wrapping
a list in a dict:
result={} - means there were no actions
result={'items':[]} - means there was a search but nothing is found
result={'items':['...',...,'...']} - found
And the template is like this:
{% if results %}
{% if results.items %}
{% for item in result.items %}
...
{% endfor %}
{% else %}
Nothing found
{% endif %}
{% endif %}

There are several "generic" auth views: login, logout, password change, password reset. These can be found scattered across django.views in trunk/0.91 or in django.contrib.auth.views in M-R.

ManyToMany with related_name?
I'm trying to create a model that relates back to itself with a ManyToManyField. Here's my model:class PressRun(models.Model): starttime = models.DateTimeField(db_index=True) endtime = models.DateTimeField
(validator_list=[endAfterStartValidator]) name = models.CharField(maxlength=100,blank=True) recurringitem = models.ForeignKey(RecurringPressRun,blank=True,null=True) edition = models.IntegerField(choices=EDITION_CHOICES,blank=True,null=True)
press_id = models.IntegerField(choices=PRESS_CHOICES,blank=True,default=1) insert_into = models.ManyToManyField('self', null=True, blank=True, related_name='insert')
The problem is that the model doesn't seem to use the related_name option. PressRun objects have an insert_into property, but no insert property. I'm actually trying to say that the result of a PressRun can be "inserted" into another PressRun, but I don't want to make a separate object (like PressRunInsert or something). I'd like to use a simple ManyToMany, but the objects don't have a distinction between "inserted into" and "insert of".
Does that make sense?Dave

Ecommerce & Django
Hello everyone, I've been lurking around here for a little bit, trying to get a feel for Django. I recently had the need to set up an eCommerce site for my wife. After looking at all the alternatives, I chose OsCommerce which seems to be the dominate Open Source ecommerce application. It is pretty mature & has thousands of users. For the most part, it does what it says it does. However, after I've spent the last couple of months trying to get it working the way I like, the PHP warts & overall design are getting to me. My site is now functional but I'm really scared to make any changes for fear of the whole house of cards coming down on me. I'm no PHP expert and won't go through the cons of the language but let's just say that the more I worked with PHP, the more I wished I were working with Python! So, I started looking at frameworks to setup my site using a python based solution. After looking around, Django looks like a good bet. There are certain problems with OsCommerce which are going to be non-issues with a Django site: - Templating: In OsCommerce there are some options but they're kludgy and can interfere with other pieces of code or add-on modules. Obviously templating is a core part of Django. - Search Engine Optimize URLs: Before diving into this project, I didn't realize how many people worked so hard to get URLs looking nice so that they show up higher in search engine results. As you can imagine, trying to modify these through PHP can be painful. Django's URL capabilities should make this another non-issue. - Performance and Caching: Scalability and general performance are huge issues. In stock OsCommerce, you can have nearly 100 db queries for 1 simple page. Without caching, you have some real performance headaches. The caching capability & proven scalability lead me to believe that Django will make these issues less of a concern going forward. There are some concerns I have around Django for this application: - Lack of ecommerce modules: There are lots of things like FedEx, USPS or UPS shipping interfaces that are available that would have to be re-coded. Also, payment processing modules would have to be created from scratch. I don't think these are show stoppers but it is a challenge. - Admin interface: I'm a little concerned about whether or not the default admin capabilities within Django will be usable for store management. I might have to come up with some other alternatives & it feels like that's uncharted territory in some aspects. - Deployment on shared hosts: This probably isn't too big a deal but it's certainly not as straightforward or ubiquitous as PHP app deployment. So, what is the point of my lengthy post? I know some people have started (or have completed) work on their own stores. Is there any framework out there that I can leverage or do I have to "roll my own?" I think it would be a great thing for this community to create a store framework. The Django plusses I mentioned would be awesome in a complete solution. I think it would also attract a lot of users to the project. Is there interest or any activity in this area? I'm willing to hack through by myself but I think if there's anyone that is an expert, we could move through this a lot more quickly.

Re: Problem with threads accessing MySQL database
Hi kopikopiko, I thought I'd chime in on how I'm solving a similar problem. I also have a task scheduling app written in Django, but I actually run the tasks through Django rather than outside of it: I have a special view (/tasks/trigger) which remembers the last time the view ran and checks for any tasks that should have run since the last trigger time. It then simply loads and runs each task in sequence. Outside of Django I have a schedule NT/Windows task that runs every 5 minutes and just does an HTTP get of the trigger view url. I can get away with this since my tasks are simple and usually take a few seconds to run so I don't mind running them synchronously. I did think about your approach, though, and I was going to load all the DB data that defines the task, then fire off the task on a background thread, then have those tasks update the DB with their stats directly (each making their own MySQL connection and doing direct SQL). I was going to do it that way since I didn't want my task scripts to be dependent on Django's ORM. But like I said, I never went down the multi-threaded route because I wanted to keep it simple and at this point, I don't need to. -Dave --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: querying for an empty set in m-r?
Russell, Just wanted to thank you for responding to my post. You did interpret my question correctly, though I was obviously hoping to avoid using raw SQL. Anyway, thanks again.

Re: querying for an empty set in m-r?
Max, Just wanted to thank you for responding to my question. You are correct that the list comprehension is pythonic, though I was ideally looking for a efficient method from a database perspective.

Pluggable User/Registration/Authentication App?
I am pretty much fresh blood to Django and I am looking for a pluggable application that will provide some sort of front end interface to handle user registration and authentication to an existing project. For many sites a user system is key, I have been reading around and found the authentication model page: http://www.djangoproject.com/documentation/authentication/ However it would be great if there was some sort of pluggable application that does the basics, like I said most developers/designers would find this useful for their projects. So any ideas where to start on this? Does anyone know if anyone has already made something like this to build off of? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

You could do: tags = [tag for tag in Tag.objects.all() if tag.article_set.count() == 0] n queries for n tags, but it is "pretty" Python. Doing db-cleanup shouldn't happen all that often, so you probably don't need the best performance, and I'd just stick with the list comprehension.
