Signal for 'ready to receive requests'
I've been looking around the limited signals documentation and the code hoping to find a signal that basically says 'django is done importing models ready to receive requests', but haven't found it yet. The closest I've found is connecting a receiver to request_started, and then removing that receiver after the first call... but that isn't quite what I was looking for. Is it there or should I keep looking? If it's not there, would this be something useful to consider adding?

This is a known problem, and one of the many reasons that the forms framework is being replaced with 'newforms'. There is no workaround (that I am aware of), nor are there plans to fix the (many) problems with the Manipulator framework.

Too many queries generated by ChangeManipulator
I've got a model with a few foreign keys. Normally this isn't a problem except in one case when I create a Profile ChangeManipulator, it results on the following query repeated once per GameOfInterest associated with the given Profile: 'time': '0.046', 'sql': 'SELECT "game_room_app_game"."id","game_room_app_game"."name","game_room_app_game"."genre_id" FROM "game_room_app_game" ORDER BY "game_room_app_game"."name" ASC' Obviously, the performance deteriorates rapidly as the number of GamesOfInterest added to a Profile increases. Is there any way to avoid this? Here is the relevant portion of my model file (with some fields removed for brevity). Essentially, I have a GameOfInterest that associates a Profile to a Game, and a Profile can have any number of these: class Game( models.Model ): class Admin: pass class Meta: ordering = ( 'name', ) def __str__( self ): return self.name name = models.CharField( maxlength=60, unique=True ) genre = models.ForeignKey( GameGenre ) class Profile( models.Model ): class Admin: pass # waiting on bug #2076 #ordering = ( 'user__username' ) def __str__( self ): return self.user.username user = models.ForeignKey( User, unique=True, edit_inline=models.STACKED, max_num_in_admin=1, num_in_admin=1, core=True ) ) class GameOfInterest( models.Model ): class Admin: pass def __str__( self ): return self.game.name game = models.ForeignKey( Game, blank=False ) profile = models.ForeignKey( Profile, edit_inline=models.TABULAR, num_in_admin=1, core=True, blank=False ) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Cannot resolve keyword '___' into field
The solution I implemented for my app has worked without a hitch at
the moment. Unfortunately the problem still persists in the admin.
eg: when I log into the admin, the first page always shows up the
'Auth' and 'Sites' apps but intermittently shows up the app i've
written.
I would like to go through the admin and apply my fix to it. I'm just
wondering what files I would have to look through. Do I only have to
go through the django/contrib/admin/ folder and all the files in it?
Regards,
Mark.

As the ticket you found suggests, we're aware of the problem and I think
we understand the latest reason it's not working (middleware is
introducing an extra curve-ball for some reason). Fixing it is very hard
because the problem is so non-reproducible. It's quite likely that
somebody running your exact code on a different machine or with a
different version of Python will not be able to reproduce the problem.
At the moment, I'm probably the most likely person to end up fixing
this. However all my free time for Django is taken at the moment on some
other items, so all I can encourage people who find these problems to do
is try to shuffle things around a little, as you've done, in the hope of
finding a workaround.

Malcolm

Should file uploads work in 0.96 admin?
I'm just wondering my expectations are correct: Using 0.96, given a model with an ImageField, the admin interface gives me (what looks to be) a file upload widget. I should be able to select a file from that widget, and once I save the model, it *should* copy my image file into the upload_to path, correct? many thanks, andrew --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: non-editable model elements and generic updates
Just ignore me. I like to overlook obvious bits then wonder why it isn't working. I was using "editable=False" in several of the fields I wanted to hide, but missed one. So the "editable=False" solution *is* the fix I was looking for, I just gooned it up by missing a field. :-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

non-editable model elements and generic updates
What is the best practice for handling this? Let's say I have a form with 3 fields: name, b-day, status I want a form that will allow the user to edit "name" and "b-day", then keep "status" whatever it was before the edit. Should I send this through as a hidden field? Of course, I'm talking about a much larger model here, but simplifying for the sake of er... simplicity. Actually the model has about 15 elements and the user will be editing about 10. The problem is this: if all 15 fields are filled, and some are set to "editable=False", the form goes through fine, but all the fields not in the form are set to null, or otherwise wiped out. How can I get around this? Is my only option to pass all that info through as hidden fields? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Get_FIELD_url issues
Awright. I just know I'm missing something stupid here.
I have a model for file attachments that are uploaded. In one of my
templates, I'd like to display a URL whence the attachment could be
recalled. So I've put in {{ a.get_bugfile_url }} in the template, but
the output HTML looks like Title. I can't retrieve the
URL. However, if I test this in the shell, calling a.get_bugfile_url(),
I get exactly the URL I'm expecting. Interestingly, get_bugfile_filename
also doesn't work in the template, but does in the shell.
Anyone tell me what stupid thing I'm missing? I'm using the most current
SVN version of django (trunk).
Thanks,
J

maybe i'm missing something here, but is it really important for you to
use only through-a-group gained permissions?
isn't it enough to simply check for the given permission?
because if it's enough, then simply use the "perms" variable in the
templates.

The only thing that worries me is repetition. It seems like it would

Re: View (maybe middleware?) question
hmm, yeah, that's about what I am looking for (the site lang
approach). I'll look into that some more.
For this particular app, there are no stored user profiles (e.g. there
is no logging in), so as much as I'd like to store this setting in a
user profile, and requiring login, I can't guarantee that here.
The primary view that will take advantage of this is a registration/
survey page that I want to have different themes on depending on the
partner/ group that is directing users to the site. When someone
registers, I need to track the theme as well, but it's more for the
look and feel when the users visit the site.
I can probably get away with restricting it to this particular app (in
the middleware) and just create a list of common view urls that it
should ignore when looking at the theme portion of the url, so as to
avoid strange path catches.

Yes, basically, except that you're setting a session parameter on
every page load, which is what you're checking against, rather than
against the last time the user saved something.

Yes.

Why would you need to actively cause them to expire, as long as
they're refused when someone tries to accomplish something with them?
If you log the user out upon any request after the expiration time,
you get the same effect. The session becomes an expired session
whether or not you delete the cookie, and whether or not the user ever
returns to the site. Not sure if I'm explaining this clearly.
In pseudo-code...
on every request:
if (session['last_activity'] > (now - 30min)):
user.logout()
session.destroy()
session.create()
session['last_activity'] = now
redirect('/login_url')
else:
session['last_activity'] = now
execute_requested_view()

ForeignKey to ForeignKey
I have 3 models, Shift, Person & Shiftmap. class Shift(models.Model): name = models.CharField() date = models.DateTimeField() class Person(models.Model): first_name = models.CharField() last_name = models.CharField() class Shiftmap(models.Model): shift = models.ForeignKey(Shift) person = models.ForeignKey(Person) This is a basic run down, not the actual models. You get the idea though. I want to use Person.shiftmap_set.all() but I want to sort it by Shiftmap.shift.date. Is this possible? Basically I need to use a Person object, to sort all Shifts assigned to it, via Shiftmap, sorted by Shift.date.

Re: Many-to-Many with quantities
Because of the dependants you might need to either manually add the tables to the db or if you don't have any values in that table delete all the rows in pizza and run syncdb again. Sometimes when working within the same class the syncdb doesn't change the database all the way (and rightly so). Give that a try and if it still doesn't work we'll try a different solution.

Re: special session-time usecase
Why not store a parameter in the session indicating when it was last saved. On each page load, first check that parameter and if it's too long ago, discard the session and begin a new one. Then update the parameter with the current time. You may need middleware to accomplish this, but it ought to be extremely simple to implement. It won't get rid of the actual cookies if the user doesn't return, but it will take care of session expiration, and the old cookies shouldn't matter, since they contain no session data except the ID, which you're invalidating after a certain amount of time anyway.

Re: Many-to-Many with quantities
Thanks to you all, I took something from all the replies and I wrote this modifying Michael code: class Topping(models.Model): name = models.CharField(maxlength=255, unique=True) def __str__(self): return self.name class Admin: pass class Pizza(models.Model): name = models.CharField(maxlength=255, unique=True) def __str__(self): return self.name class Admin: pass class PizzaTopping(models.Model): pizza = models.ForeignKey(Pizza, help_text = 'Toppings to go on Pizza: num in admin is how many will show up in Pizza', edit_inline = models.TABULAR, num_in_admin = 3, core=True) topping = models.ForeignKey(Topping) amount = models.IntegerField() I got problems in admin: I inserted a few toppings, now when I insert a new pizza with his toppings the toppings and quantities aren't saved. No error messages, but inspecting database reveals no entries for the auxiliary table pizza_pizzatopping Any hint? I'd like to solve this problem, leaving a solution for the archives.

So it sounds like door number one will do for us. Currently we use Akami caching for the Drupal version of the site, but it's a very expensive way to go. I'll investigate caching solutions supported by Django. A quick glance at the memcached site says that it's used on LiveJournal, which gets over 20,000,000 page requests per day. Excellent.

Re: Many-to-Many with quantities
Nis; Thanks for catching that I left the manytomany field there. There is no need for that. revised code: class Topping(models.Model): # ... class Pizza(models.Model): # ... class PizzaToppings(model.Model): pizza = models.ForeignKey(Pizza, help_text='Toppings to go on Pizza: num in admin is how many will show up in Pizza', edit_inline=models.TABULAR, num_in_admin=3) topping = models.ManyToOne(Topping) amount = models.IntegerField() #... This will appear in the Pizza part of the admin as a stacked model and allow you to use or add as many as you would like. So you can remove the amount if you just want people to be able to add double cheese by adding a second cheese topping. Thanks Nis and good luck Giovanni.

I believe this is the best way to do it. However, this generally gets composed as class Pizza(Model): #don't reference toppings here class ToppingAndQuantity(Model): pizza = ForeignKey(Pizza) topping = ForeignKey(Topping) amount = PositiveIntegerField() The information you want (the quantity) is associated with the join between a pizza and its toppings. The ManyToMany would make a situation where you could have one pizza that has both 2x Cheese and 4x Cheese. I suspect that you want just one topping per pizza, but a quantity associated with that one topping. The ManyToMany is a nice shortcut for basically creating this intermediate join model with only two FK fields in it (pizza and topping) with a little syntactic sugar around them. With the above, you should be able to do things somewhat like p = Pizza.objects.get(id=1) for topping in p.toppingandquantity_set: print "%s x%i" % (p.topping, p.amount) -tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Your model has the problem that two pizzas can share (Mozarella, 2) - leading to problems if you modify one of them.

It would also be helpful to know things about the usage patterns--particularly the read-to-write ratio and currency-demands. If most of your hits are reads, and stale data is okay (only updated every N minutes), then you're a top candidate for several of the caching solutions supported by Django. Or even front-end caches that prevent Django from even seeing the request. If most of your hits are reads, but they need to have the most up-to-date info, you can use a replicated DB cluster where writes are synchronized lockstep across the cluster, and then a load-balancer farms out the reads across the cluster. Or, you can have as part of your writing (perhaps in a save() call), calls to your cache-controller to invalidate affected pages. If you're write-heavy, best wishes! ;-) Data partitioning may help, as might a multi-master DB configuration. -tim --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Many-to-Many with quantities
Hi, I searched about this subject and found only a few very old posts, so maybe there is a better solution now. As you may guess the model I'd like to code is similar to the Pizza - Toppings you know from the "Creating Models" documentation: class Topping(models.Model): # ... class Pizza(models.Model): # ... toppings = models.ManyToManyField(Topping) And what if I need to say that I can have two or three times the same topping on my pizza? Something like twice mozzarella cheese and 3 times green olives topping? I though about an intermediary class and indeed this is the same solution found in those old posts mentioned before: class Topping(models.Model): # ... class ToppingAndQuantity(models.Model): amount = models.IntegerField() topping = models.ForeignKey(Topping) class Pizza(models.Model): # ... toppings = models.ManyToManyField(ToppingAndQuantity) I think it's ugly. Can you suggest me a better solution? It's that intermediary class really needed?

Re: Moving Images to Amazon S3
I think my question wasn't clear: we're having NO problem putting files on S3, that's dead simple (ie what Holovaty blogged about). What we need to do is take an *in-memory Image* and put it directly onto S3. We need a way to convert a PIL Image instance into a format S3 can accept WITHOUT having to first save the Image to the file- system. S3 accepts the kind of string that gets returned from open(afile).read() I was trying to wrap the result of img.tostring() in the StringIO class, and then put that on S3, but that doesn't work either... --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Problem with flatpages and absolute urls
I have a problem with flatpages. When putting links in my templates, I use absolute URLs without prepending http://hostname.com/ For example, Home gets interpreted by the browser as a link to http://hostname.com/, and all is correct. However, when a flatpage is being served, those links get interpreted literally, so the link now is http:/// which is of course useless. I suspect this is something to do with the 404 response that triggers something in firefox. So what am I supposed to do ? Should I prepend everything with the hostname ? How can I get the current site (so I won't couple the template to the site) ?

Checking group permissions in template code
After reading the docs and looking for posts relating this problem
here and in .developers, I found no "standard" way of checking for a
user's group permissions in the templates.
So what I did is to add the following method to auth.models.User
(yeah, yeah, it *should* be in appname.models.UserProfile):
def group_permissions(self):
class GroupPermissions:
def __init__(self, permissions):
for perm in permissions:
setattr(self, perm, True)
def __str__(self):
return 'The user belongs to the following groups: %s' % \
', '.join([k for k, v in self.__dict__.iteritems()])
return GroupPermissions(self.get_group_permissions())
which lets me write something like the following in my templates:
{% if user.group_permissions.permission_name %} draw custom menues for
this particular group here {% endif %}
So, is there already a way to do this and I missed it? If not, given
that it is apparently not advisable (is it?) to extend the
auth.models.User class, how about we add it?
-Facundo.

Re: multilanguage site
Grupo Django napisał(a): > Can you please provide me some document where I can find some > information and examples? This is how this all gettext machinery works. It doesn't matter where in the sources the key is located, if gettext finds the key, it will replace it with its translated value or use the key if the translation is missing. The act of translation is unavoidable, so it doesn't matter if you use database table with translations, or use gettext machinery and translate the PO files, but it the gettext has ready-made infrastructure in Django and you don't have to do anything special to get your texts translated, providing you have done the translation. ;) You can add the keys by just extracting the texts from database table, then placing it in PO file (i.e. using some script).

IMHO I think it's quite useful and it would be a great improvement. Django is so good that it's possible to use it for very professional sites, and those sites need generally content in several languages. Moreover, it's not very difficult to implement it in the way I exposed, and the text in the main language it's still stored in the original table, not in the translation one, so it's backwards compatible. Perhaps for the English speakers it's not especially necessary but for the rest of the world, we need to use our native language and English in our sites very often. If someone tell me what documents should I look to modify the django code, I'll try to do it, and propose it. I built a complete multilingual system for a PHP framework in just a few hours. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

multilanguage site
Hello, I'm going to start a new multilingual site. I think that the django tools are very powerful for this purpose, but I need a bit more. I have to translate the content from the database and I have a few options: - Translate it using the standard way, I mean, using po files. Problems: Every time I add/modify something to the database, I have to do the same in the po file, the right way is do everything in the admin zone. - Create some tables for the translation. I have built some multilanguage sites using PHP, and in the admin zone we had a select combo box with the available languages, if you change the language in the select, the fields with translation enabled, changed. I'm thinking about creating a model for the languages with 3 fields: *id *language code (ISO 639) * language name an other model for the translation strings: * id * table * field * id_row * string In the translation table, I'll have translations for the strings that require translation in other models.ie: | id | table | field | id_row | string| = |1 | 'polls' | 'question' | 34| 'Do you like this translation method?' And then implement it within the admin zone, wich is the main problem to me because I don't feel confident yet for manipulating the admin code and if I did, I'd have a lot of problems with the updates. - Does anyone know a better solution for doing it? - Could it be implemented in futures django releases?

I have seen this error before. That time, it wasn't (technically) due to a fault in the serializer - it was caused by a model overriding the save() method. In the overridden save() method, there a query was performed on the database, but the required objects had not yet been loaded. Are you overriding save() in any of your models (in particular, anything querying StaticPage model? The only workaround I know of for this is to do your dump in stages, so that the data required by the query in the save() method is available at the time the saved object.

Migrate data between computers
Hello, I would like migrate data from my Django project on notebook (computer1) to another machine (computer2). To perform this, I follow this steps: 1) On computer1 I call ./manage.py dumpdata > all.json 2) On computer2 I setup exactly same version of my Django project. Next I call ./manage.py syncdb which create all necessary DB tables and (unfortunately for me) all fixtures+initial data (like auth_permission, django_site, admin user, etc). 3) Because all.json file contains all data from computer1, I call ./manage.py sqlflush on computer2. This give me SQL statements, which I used to "clear" all data from fresh database on computer2. 4) Now I could call ./manage.py loaddata ./all.json Is this approach correct? I ask you for this, because I have problem to load data on computer2. My effort ends with error message: [EMAIL PROTECTED] app $./manage.py loaddata all.json Loading 'all' fixtures... Installing json fixture 'all' from absolute path. Problem installing fixture 'all.json': StaticPage matching query does not exist. I don't know what I should do now. Even, if I set --verbosity 2 to ./manage.py I don't get any usefull information what is wrong. Is it possible to found somehow where is the problem?

Re: View (maybe middleware?) question
I've done something similar to this, putting the site language in the
url.
Basically you create a middleware process_request, that will take
request.path and set it to something else.
For example you might do:
request.path = "/app/theme/view/"
parts = request.path.split("/")
request.path = "/"+parts[0]+"/"+parts[2]
theme = parts[1]
#do something with the theme...
return None
Then your urlconfs will go on without knowing about the theme logic.
Beware, though: This can lead to many strange errors when this catches
paths you don't want to be processed. You also have to worry about
search engines. It might be better to apply the same middleware to
extract something from the session/query parameters.

Moving Images to Amazon S3
I'm absolutely stuck on this. This question might be more python than django related, but I figured because it deals with Amazon S3, someone here may know how to handle it. Here's what needs to happen: 1. A user uploads an image (part of a Model we have) 2. Create a 100x100 thumbnail using PIL 3. Move the thumbnail to Amazon S3 Step 3 is the tricky part for me. I can't figure out how to do it, other than first temporarily saving the in-memory thumbnail to the filesystem, re-reading the file, moving the raw data to S3, and then deleting the temporary thumbnail file: # thumb is an already thumbnailed Image instance, in memory thumb.save( temp_path, "JPEG") raw = open( temp_path ).read() # code to move 'raw' to S3 os.remove( temp_path ) This is a pretty heavy way of doing it, and I'm desperate to find a better way of doing it but am absolutely out of ideas... The S3 API requires the file data to be in the format the open(myfile).read() returns (whatever that is). Is there a way to get the same data from an in-memory Image instance, so I don't need to save/re-read/delete each thumbnail file? --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.
