DjangoBot: #django

well, I would expect a pattern something like BEGIN ; INSERT INTO foo VALUES ( ( SELECT MAX(id)+1 FROM foo ) .... ) ; COMMIT;

django 0.96.2 Errors on the call to form.save()

PhantomsDad: using which database?

How am I supposed to be able use admin.site.register? At the moment I have it at the bottom of my models.py, but when I import models.py it gets called and again and it gives me this error "AlreadyRegistered: The model StationMapping is already registered". How should I handle this?

FunkyBob: mysql

ah, Mysql

javagamer_: Are you using autodiscover?

FunkyBob: ya thats what I would have done, but i need to return the id as well

mattmcc: No, I was loosely following the tutorial and I didn't see any mention to autodiscover. How should I be using it?

Is there some reason I cannot extend the ErrorList class in django.forms.util?

mattmcc: Now I see it. Thanks.

I am using a Model Form and I want to get back text only errors, no bs ul/li list

jonesy: The Form class takes an error_class argument.

this is what I have setup: registrationform = RegistrationForm(request.POST, error_class=DivErrorList)

mattmcc: Wait. I have admin.autodiscover() in urls.py. Is there something else I should do/somewhere else I should put it?

it calls my function which extends the ErrorList class

http://mysite.com/admin gives a 404 but .../admin/ works. why?

hi, I'm getting a really strange error from code that used to work: http://dpaste.com/69221/

Add a / to the end

blips: check your urls.py

blips: Have you set APPEND_SLASH to False in your settings?

mattmcc: aah maybe

Whenever I try to import an object from models.py I get "AlreadyRegistered: The model StationMapping is already registered". What does this mean and how do I prevent it?

mattmcc: im using the default install.. should I add append_slash = false to my settings.py?

javagamer_: it might have to do with registering for the admin site

blips: No, if you don't have it set, the default is True. Which means it would redirect requests that don't end with a slash, unless you don't have the common middleware enabled.

mattmc: what can I do then?

spool: The code is almost exactly from the tutorial, could it be related to my import statement "from models import StationMapping" in views.py?

javagamer_: no that should be fine. registering is not the same as importing

javagamer_: sorry I haven't looked at the new version of the tutorial, (since major changes have recently been applied) what page are you on?

http://dpaste.com/69222/ here is my apache <location> thingy, and my urls.py am I doing something wrong?

javagamer_: have you added

javagamer_: mmm ok hold on

spool: Well, I just remade my app and refollowed the tutorial up to page 3, at which point I just copied over the bits of code which looked like they hadn't changed.

javagamer_: that can happen as a result of importing your models in multiple places using different import paths

javagamer_: such as relative imports

rozwell: So, do they all have to be absolute? Or can I just change any absolute paths to relative paths?

javagamer_: always use absolute paths

this is fucked up. Some of my fields come back as text like they should and other default to the standard ul/li

rozwell: Alright. I just thought that relative paths would give me more flexibility. Thanks.

javagamer_: they can lead to trouble down the road

rozwell: would that explain a registering problem?

spool: yes

rozwell: Thanks for the advice.

rozwell: fair enough... is this where the magic of admin.autodiscover() comes into play?

rozwell: It works now. :)

spool: admin.autodiscover() tries to import an admin module from all INSTALLED_APPS

spool: and usually admin.py contains the admin.site.register(blahblah)

spool: which would "magically" register the modeladmin with your admin site

rozwell: so why do you need admin.site.register _and_ autodiscover?

spool: so you don't have to explicitly register modeladmins

spool: that is on a per-project basis

rozwell: I guess I'm asking why would you use admin.site.register and autodiscover at the same time (as suggested in the tutorial)?

anyway, the alreadyregistered bit comes into play if you keep the admin.site.register bits in your models.py

spool: you don't *need* autodiscover - it's just a convenience rather that putting the "register" commands in your models.py (helps keep it a bit more loosely coupled, too)

spool: because if you didn't you'd have to import the model admins and register them for each 3rd party app and your own apps somewhere in your project

spool: autodiscover looks for the admin module of each installed app package so you don't have to explicitly import it

rozwell: ahhh, so I can take it out of __init__ like I used to?

it's generally best to keep modeladmin registering out of your models.py and certainly out of your __init__

keep them in the admin module of your app package

rozwell: no, I used to import admin in __init__

i don't know why the tutorial tells you to put the register bit in models.py

i guess to keep it simple

anyway, the exception has to do with how python imports/namespaces work

and you can run into similar problems with registering signal handlers with the dispatcher for example

rozwell: before nfa landed you had to import admin.py somewhere, and originally they suggested doing it in __init__

so it's best to learn how python imports/namespaces work

for determining whether the menu item is active, should I create an inclusion tag and pass the current page name?

spool: i see

rozwell: but autodiscover seems to have fixed that problem

keseldude: if it just results in style changes i would just do it with css

if I wanted to show the current page's menu item in a different color, I could do that in just css?

keseldude: certainly, just give the body element a class

keseldude: and use descendant selectors appropriately

rozwell: incidentally... do you have any ideas for my problem? http://dpaste.com/69221/

oh yeah

keseldude: i usually have a block for the body class which i override as needed

Or an id, since it'll be unique.

hm, thank you :)

mattmcc: not necessarily

spool: not really, other than an integer field is getting set to an empty string

spool: at least that's what it looks like on first glance

rozwell: yeah, that's what I was afraid of

rozwell: thing is, that code worked a week ago

spool: well work through the traceback

spool: or use pdb

ADMIN_MEDIA_PREFIX = "/media/ where does this lead to? user/mysite/media/ or user/media/

is there a django based on line spreadsheet/db manager sort of thingie like dabbleDB?

rozwell: yeah I've been trying to use pdb. Thing is I'm only calling the save method on a new object, so of course the id should be null.

blips: that leeds to /path/to/trunk/django/contrib/admin/media/

I was reading about how such an application would be bundled in django ?!?!?

webar7: url ?

rozwell: so I'm not sure what to look for

rozwell: if it makes a difference: http://dpaste.com/69223/

for dabble? ?

the summer of code 2006 suggestions page had : "add dabbledb (http://dabbledb.com/utr/) like functionality to the django admin. e.g. create a project and super user with one command line statement, fire up the development web server, and import/create/refine your model using live data from directly within the django auto admin."

marcos_ : i dont understand?

I think dabble uses another easy build web app framework based on smalltalk or something

wmealing1, mentioned on http://code.djangoproject.com/wiki/SummerOfCode... just wondered if someone did that :)
