Running django with stackless
Guys I m using threads to use concurrecy in my webapps and I find it to be needlessly slow, because most of the stuff thatI try to do with the thread are like, send messages, update a long running thread, update rss feeds etcc., ie they do not need context and Hence i do not need threads Upon researching I found an implementation of python that doesnt use C- Stacks and hence supports Co-routines. Here is my question. I want to use webpy with stackless python. The problem I m facing is there are parts of webpy that are hacked with frame operations. Is there any one who has webpy running on stackless. If so please share the patch Thanks a lot Krypton --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

sorry, shouldn't post so late I guess...
I would like to make a list of allowable arguments for filter
to supply that as a selection list on a search page.
so I have to get a list of 'model__field' like strings
derived from models (models.get_all_models())
class Poll(models.Model):
question = models.CharField(maxlength=200)
pub_date = models.DateTimeField('date published')
class Choice(models.Model):
poll = models.ForeignKey(Poll)
choice = models.CharField(maxlength=200)
votes = models.IntegerField()
relfieldargs = ['%s__%s' % (m.model._meta.module_name,f.name)
for m in Poll._meta.get_all_related_objects()
for f in m.model._meta.fields ]
relfieldargs:
['choice__id', 'choice__poll', 'choice__choice', 'choice__votes']
I can use these as (part of)arguments for filter
Poll.objects.filter(choice__votes__gt=0)
but the other way around doesn't work (from Choice->Poll)
relfieldargs = ['%s__%s' % (m.model._meta.module_name,f.name)
for m in Choice._meta.get_all_related_objects()
for f in m.model._meta.fields ]
relfieldargs:
[]
so I need some other way to get those.
Now you seem to say that the answer is in here,
In [18]: [f for f in Choice._meta.fields]
Out[18]:
[,
,
,
]
which I can see. but how do a make an expression to test for
foreignkey
(except for 'fields.related' in `f` which seems a bit clumsy)
and then of course I would like to find the 2nd (or higher) order
cases too
'model1__model2__field_of_model2'
any simple ways to find those?
thanks for your help.

The easiest way is to use the ``latest`` operator:
FrontPageEntry.objects.latest('added')
This will return the entry with the most recent 'added' date.

A patch containing the code is attached to ticket #2333; You may also need to apply the patches from tickets #3390 and #2720 depending on the complexity of your data model and your database backend. The original intent was to allow developers to write unit tests, and have data in the database during that test; however, it can also be used to put a whole lot of initial data into the database. It's not documented yet, but the modeltest that is part of ticket #2333 should give you an example of how to use the fixtures framework programatically.

Problem with a Class
Hello,
I found this very interesting post :
http://groups.google.com/group/django-users/browse_frm/thread/bb7f406bffd697f5
Then I tried to apply this modele to mine, but I have trouble !
Here is the class :
#
class VideoSeq(models.Model):
video = models.ForeignKey(Video,edit_inline=models.STACKED,
db_index=True)
Title =
models.CharField(maxlength=200,null=False,blank=False,core=True)
Number = models.IntegerField(maxlength=2,db_index=True)
Duration = models.IntegerField(maxlength=2,db_index=True)
has_lang = models.CharField(maxlength=2,null=False,
db_index=True,choices=HAS_LANG_CHOICES,)
has_thumb = models.BooleanField(db_index=True)
is_done = models.BooleanField(db_index=True)
updated_at = models.DateTimeField(auto_now=True)
def delete(self):
#
flv_path = "%s/seq%s.flv" % ("/home/vids",self.Number)
img_path = "%s/seq%s.jpg" % ("/home/vids",self.Number)
#
if os.path.isfile(flv_path):
os.remove(flv_path)
#
if os.path.isfile(img_path):
os.remove(img_path)
#
super(VideoSeq, self).delete()
#
def __str__(self):
return "Seq %s" % (self.Number)
class Admin:
pass
##
I don't understand why I have the following errors while using it :
name 'flv_path' is not defined
name 'img_path' is not defined
name 'VideoSeq' is not defined
Any advice is appreciate :)
Regards,
xav

Creating HTML emails
I've been able to create Plain text emails to send to users with an authentication link which work well, however I'd like to improve the look of these by outputting in HTML with a logo.

Trouble with models
Hi, I know this isn't necessarily a Django specific problem but I am using django to develop my system so here goes. Basically I am making a system for a football team (soccer for you americans) and can't seem to get my head around a way of possibly doing it. I've left out some of the other stuff I don't need but what I'm trying to model is: Team (e.g. Senior Team 1st's, U7's etc) Players which belong to a team/squad Squad (which consists of players that are part of a team e.g. Senior Team) The confusion I am having is around the team/squad situation. A team (say Senior Team) Isn't just one "team" it is a set of teams e.g. Senior Team 1st's, Senior Team 2nds etc. I don't want a player to be replicated but if they belong to a team they also need to belong to the squad. (I hope I'm making sense) For instance the situation below: ManchesterUtd 1st Team consists of players (lets say paul scholes, rio ferdinand, wayne rooney, christiano ronaldo) The squad includes every player who no longer belongs to the youth academy (obviously alot of players possibly up to 100) But the team is picked from the squad. And if a player from the 1st team (wayne rooney) was recovering from an injury or wasn't playing well he could be dropped to the Reserve Team. I am unsure of how to model this without having wayne rooney belong to the 1st team, and have a duplicated one in the second team? Any help is very very much appreciated.

are the Installed apps settings necessary?
I posted this yesterday, but It did not show up, strange. According to the manual, one has to add apps to the INSTALLED_APPS setting tuple to make the usable in a project. I have created several test apps with views wired to urls in the projects url conf file, I was able to call up all urls without any problems. What is the main advantage of listing the apps in the INSTALLED_APPS variable? Not that I`m complaining, Im just curious, in fact if its not a necessity, It makes my apps more portable, I just copy the apps I need to another Project folder, wire up the urls and they work, one step less to take. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

how to postpone HttpResponse but still get new requests
Hi,
i got a producer-consumer class which await new items from the
clients, does sth with them and provides them to all clients.
the url "getNewItems" is for getting the new Items and vice versa.
my problem is: when i wait for new items, i cant get new, cause this
stuff is all in one thread.
is there a way to save the request so i can send a response later
(when the are new items).
or maybe i could start 2 threads per client or sth ...!?
any idea?
from foo import producerConsumer
def getNewItems(request):
p = producerConsumer()
newItems = p.consume() # wating for new items here
return HttpRespone(newItems)
def putNewItem(request):
p = producerConsumer()
p.produce(request.__getItem__("item")) # notifyAll here
#no response needed here

Inserting dummy content
Hi there! I was wondering if there's an easy way to insert a lot of dummy content into a couple of models. Have anyone written something that does this? The reason I'm asking is that I'm writing this social networking app, and in a while I'm going to present it to a company. It would be nice to have a bunch of dummy users and dummy content by then, just to illustrate the power of the built in admin filtering possibilities. I'm not to keen on creating fifty different users, and just as many user profiles and content, if you know what I mean. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

oldforms, file upload, rename & save
Hi all, I spent the last 2 hours fighting with a model.FileField that I wanted to save the file with a custom name (job number of a hylafax server). I found a related thread here: http://groups.google.com/group/django- users/browse_frm/thread/f337faf5ef5d8f9a/3c183363b21b496d? lnk=gst=file+upload+form=7=en#3c183363b21b496d so I tried to define a save as suggested: def save(self): oldname = self.file_field # rename & move file to new name if needed self.file_field = newname super(Fax, self).save() this does not work for me. It seems save method is called twice by the generic view create_update within the call 'manipulator.save(new_data)'. The fist time self.file is empty the second already has the automatically generated filename. Why is it called twice? Now I call os.rename but wich should be the correct way to do it?

new forms - problem populating with data from a table
I'm new to Django and a relatively inexperienced programmer. I've
started working with the new forms and have been able to take user
input, validate it and write it to the table. Really slick and with
minimal code. Great.
I now want to take an existing user record and create an edit account
form, where the data entered by the user in the registration form is
represented and available to edit. Seemed simple when I set out to do
it, but I can't seem to populate the form.
Should I define which data goes into the form fields using the
'initial' data in the Form definition? If so, how would I do this,
because I don't know the user_id and can't place a -
userid=request.user.id request in this definition.
This would suggest that I do the form population in the view
definition. At the moment it looks like this:
if not request.user.is_authenticated():
return HttpResponseRedirect("/userlogin/")
else:
if request.method == 'POST':
form=UserAccountForm(request.POST)
if form.is_valid():
user_nm= form.clean_data['username']
# rest of form input and code validation
return render_to_response('account.html',
{''form':form})
else:
form=UserAccountForm()
return render_to_response('account.html',{'form':form})
However, all of the fields are empty (not surprisingly because I've
not linked with the data)
Can anyone give me a bit of guidance on populating the form from the
table?
Thanks

python manage.py broken
Hi all
Today I have moved a project that I have been working on to
subversion.
Prior to doing this I made a copy of the source tree and remove all
the *.pyc and the "dot something" files. I then imported the whole
tree to a subversion repository and checked it out again. I worked on
it all day, and committed a few changes but tonight I realised that
python manage.py wasn't working anymore at all (even though the site
works fine through apache+mod_python) ! I include below the error
message when I try the shell.

I have the same problem on my OSX laptop and debian Etch server so I

before importing it to my subversion repository but I can't figure out
why.
Any help would be greatly appreciated.

Trouble with relations
Hi there! I'm currently working on a project which mixes user generated content with journalistic content. The system lets users vote on an article, and articles with many positive votes will come up in the admin-panel, so that the moderators can label the entry for front page status. class FrontPageEntry(models.Model): added = models.DateTimeField(auto_now_add=True) entry_id = models.ForeignKey(Entry, raw_id_admin=True) This model above is the one used to set the newest feature-article on the front page. What I'm a little confused about is how I'm going to get this displayed! I guess I'll have to call Entry.objects.filter(ARGS HERE), but exactly what args I should use I don't know.

I took a look and traced the bottleneck to lines 125 and 127 in
viewPlan.html. The problem was as Malcolm hinted -- you're
doing a foreign key lookup ({{ workout.workoutType.name }})
for each iteration of the for loop.
I changed line 55 of views.py to use select_related() instead
of all() and it solved the problem as now it no longer needs
to hit the database for every iteration.
- workouts = plan.workouts.all()
+ workouts = plan.workouts.select_related()

Using the signal system might be overkill here. Can you achieve whatever you want with your own save() method (remember that you can then call the model's default save() method after doing your own stuff)? If you can do that, then a common way to check if the model is being created is to check the automatically created "id" (surrogate primary key) attribute. If it's empty, the model hasn't been saved yet (since it doesn't have a database-assigned primary key value). This doesn't work in cases where you manually assign the primary key value, but it is sufficient for many common uses.

Use of post_save on newly created objects
Howdy all, I was investigating post_save to perform some associated setup for an object after it's created. My only concern is that I can't seem to find any way to check if the object was created on this call to save()... I only want to perform the setup the first time the object is saved. So... Is it possible to perform a function (via post_save or some other mechanism) when a given object is saved for the first time? Perhaps the addition of a post_create signal could be a solution, but I didn't want to bring that up on django-developers until I asked here.

I really tried hard to understand your problem, but then my brain
started to leak out of my ears and I had to stop. :-(
Could you post an example of how all these models are related? You seem
to have Relmodl2, model2 and model1 and I'm not sure what all the
linkages are.
I think what you are asking is why does the reverse end of a ForeignKey
show up in get_all_related_objects(), but the forward direction does
not. If that is the question, the forward direction (the ForeignKey
field itself), is just an object of class ForeignKey in the _meta.fields
attribute on the model it is defined on. So you need to inspect the
class types in _meta.fields to see which are the forwards relations.
If that isn't your question, I apologise and ask only for a simple
example to illustrate the problem.
Regards,
Malcolm

In the database it is 75, same here. But the html widget was getting rendered with maxlength=30. I just realized I created a forms.py for it to define the html form.

Re: use forloop.counter0 as index?
Thanks for the response Aidas! It was a big help to know that it was
not
possible. It got around the problem by writing a custom tag "ifin". So
I can do:
{{ ifin item list_of_items }}
html to output if item is contained in the list
{{ endifin }}

Re: how to make a list of allowable arguments for filter()
sorry for the previous post. accidentally pressed send too early.
I can find the models which have a certain model as a ForeignKey like
this
modl=models.get_model('myapp','model1')
relfieldargs = ['%s__%s' % (m.model._meta.module_name,f.name)
for m in modl._meta.get_all_related_objects()
for f in m.model._meta.fields ]
relfieldargs
Out[ ]:
['relmodl2__id',
'relmodl2__name',
'relmodl2__foo',
etc.
]
where {relmodl2__name:value} etc can be use as argument
to modl.objects.filter(...)
this works if model Relmodl2 has model2 as ForeignKey
but not the other way round. is there an eay way to find
those model and field names?
for example relmodl2.objects.filter({'model1__nr__gt':5})
where I'm looking for the other allowed strings like 'model1__nr'
or is there an alltogether easier way to do this.
thanks-abe

Re: changing maxlength html attribute

Re: Best Practices for faster template rendering
The app I have is pretty simply as I'm just beginning so I didn't bother to try and make it any smaller. I've ZIPped the entire project directory and it can be downloaded here: http://www.roadtoboston.com/media/RoadToBoston.zip I have a batch file called runserver.cmd that would run the local test server. It sets the PYTHONPATH to include reportlab which I'm using (and is also incuded in the ZIP file). Django is it my site-packages. The top directory has an SQL file called roadtoboston_test.sql that you can use to recreate my data. I removed my MySQL database credentials from the settings.py file If you do manage to get it running, the URL: http://localhost:8080/trainingPlans/viewPlan/1/ will take you to a page that takes anywhere from 17-19 seconds to render.

Don't worry. You didn't offend anybody (at least not me). I was just trying to set some expectations about how fast you might expect a solution (you got some quick responses, but not full solution). If you want to move to another system, that really isn't going to bother anybody either, but I was trying to suggest that then you have to learn two new things and the time invested might match the time required to see if we can unravel this one. > I certainly wasn't expecting that anyone was going > to spend a whole lot of time trying to figure out if I was doing > something wrong, or if there was some kind of Django issue. > > My original post was to really geared to finding any resources that > might give some best-practice guidelines Barring that, I was really > only hoping for any quick or easy suggestions others may have. We don't really have any guidelines like that because "do the obvious" generally works very well. It really is surprising that you're seeing this sort of behaviour and I'm sure I'm not the only person who read your mail, sat up and thought "that looks very odd". [...] > Now that I'm aware that others are actually trying to reproduce my > problem, I'll stick with it for now and also try and do some more > digging on my own. Anything you can do to reduce your code to a small example that exhibits the same behaviour would definitely make things easier. Failing that, the code you have now is a good substitute (we can untangle most things with enough effort). Looking at the views.py file you provided earlier, it looks like you are on the right track with inserting the timing statements to split up the work, but it's not quite obvious where the time is going yet. So if we have something we can replicate and then pull on the strings to see what happens, that will be great.

In general, Django templating is very fast, and you're not doing anything silly as far as I can see from the partial code available. But yeah, we'd like to figure it out to see what needs to be improved.

It's only been 48 hours since you posted the original problem and less than 24 hours since you posted a portion of your code that causes the problem. It is very unusual behaviour for Django; the templating code is normally very fast, but this isn't a trivial thing to work out. Anybody working on this problem (including me), has to work up the necessary wrapper code to try and replicate the problem and create some test data and hope we see the same thing. If we don't, we have to bounce it back to you to get some more information. So understand that this can take some time. I didn't have time to do that work during the week; I'm hoping I might have time this weekend, since it is a problem worth looking at and understanding. If you were able to reduce your problem to a self-contained working example, that would help a lot. How much can you remove from the template before the problem goes away (i.e. are the for-loops the only critical piece)? How small can the data set be before there is a major change (does the time taken vary proportionally to the size of the data or is there a catastrophic increase at some point)? 84 rows of data is basically nothing, so that shouldn't have any effect, but it would be interesting to check. So if you really want to learn a new templating language, obviously go for it. But it may be a reasonable option to just hang out for another couple of days and give us a chance to look at the problem and get back to you with any queries. Hard stuff sometimes takes some time to work out. Best wishes, Malcolm --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I'm not surprised you are considering alternatives, 16-18 seconds is an unacceptable amount of time for template rendering. Did you verify that you are running with the fix for #3441? I think you need to be at SVN revision 4461 or higher. While #3441 sounds like a minor issue, when I hit it it had a huge impact due to the contents of my template context; there was a tremendous amount of work being done to build a humongous error string that was simply tossed away by the calling code. Of course this may not be the problem that is causing your excessive times. If it isn't I'm convinced it must be something similar, because I can't believe what you are seeing is expected.

Re: Best Practices for faster template rendering
I incorporated ReportLib to generate a PDF of the same data that I'm trying to display on the web and the PDF gets created in about 2 seconds as compared to the template via Django which is taking 16-18 seconds. Both routines share a common method that does all the data retrieval and manipulation before generating the output so I know the database and SQL is not a factor. This is turning out to be very distressing. I'm starting to look at other template options. I may give Cheetah a try this weekend.

Re: Best Practices for faster template rendering
This is a total shot in the dark but are you running with the fix for ticket #3441? If your template does anything to cause VariableDoesNotExist to be raised during rendering, #3441 might apply. Without the fix the entire contents of your context is repr'd to build the exception message that is then most likely thrown away. With the fix the message is only built if the exception message is actually needed. The fix was made in the last few days.

That way you don't use all the memory in the world, and you're letting

Problems with low level caching and locmem backend
I'm trying to put in the cache a simple Python list made of unicode strings. The strange thing is locmem crashes badly during the first retrieval of a cache hit. The same code with the simple backend is like a breeze. I looked into locmem.py and simple.py backends and as the traceback states the problem seems to be locmem's get() which uses copy.deepcopy() to avoid aliasing (see http://code.djangoproject.com/ticket/599). The whole thing seems a little wierd to me because I know deepcopy() can handle a simple list made of unicode strings. I also tried to print verbatim the content of the cache before the crash and there's nothing strange in there. The full traceback is here: http://dpaste.com/hold/5482/ I also found this ticket: http://code.djangoproject.com/ticket/3012 Basically the person wants to revert #599 I'm not sure if it's right to post this also to the developer list because I'm not sure it's a Django problem.

Russell, can I persuade you to explain what is > going on here? :) self.client.cookie (renamed to cookies in [4464]) is a SimpleCookie object; this object wraps the ability to easily create HTTP headers out of a cookie. You need to get the value attribute of the cookie to return just the value of the session cookie, rather than the full header information. That value, which is the session id stored as a cookie, is passed to instantiate the SessionWrapper. SessionWrapper is essentially a dictionary-like wrapper around Session.objects.get(). The session id instantiates the session wrapper, loading and decoding the session information from the database, and you query the wrapper for individual session data. Does this help explain the process? Yours, Russ Magee %-) --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Sorry - my mistake (I said I didn't run the example! :-) You are completely correct. The client keeps track of the cookies, so you need to use self.client.cookie.get(...) That said - in [4464] I have checked in some changes to the test client that automagically create the session wrapper for you.

Re: Automated testing using Client - how to test/assert the value of session objects
Hi Russ, Thanks for your prompt reply. I tested the solution you suggested and came up with some questions. Here they are. > session = > SessionWrapper(self.cookies.get(settings.SESSION_COOKIE_NAME, None)) > self.assertTrue(session['key'], value) > First of all, I could not find a SESSION_COOKIE_NAME in settings. I have a feeling that even though I am using a pretty recent SVN checkout of django, I might not have the correct settings file. Second, it would seem that the code fragment given above expects the test class to maintain a list of cookies. Pardon my ignorance, but should I explicitly create and maintain a list of cookies in the test class and use them as necessary? I am confused here, for as the test uses a test client, I thought the cookie should probably come from the _client_. Say something like this. session = SessionWrapper( self.client.cookie ) Client does have a cookie attribute which is initialised to use a django.http.SimpleCookie object.

Should newforms security fixes be posted to django-announce?
Hello. I sent a e-mail to the django security list last Friday about a XSS vulnerability in newforms. The bug was fixed on Monday in SVN revision 4460. Adrian and Jacob didn't think that it was worth posting to django-announce about it, since it only affects newforms. The justification given was that newforms is mostly undocumented and bleeding-edge, so there won't be many people using it. I'm disconcerted about this, because I'm planning to launch my own newforms-based app in a matter of weeks and I'd much rather not have to check the Subversion logs to find out about any security bugs. I decided to use newforms for my project based on these two statements on the Django web site: "The legacy forms/manipulators system described in this document is going to be replaced in the next Django release. If you're starting from scratch, we strongly encourage you not to waste your time learning this. Instead, learn and use the django.newforms system, which we have begun to document in the newforms documentation." "Should I use the official version or development version? The Django developers improve Django every day and are pretty good about not checking in broken code. We use the development code (from the Subversion repository) directly on our servers, so we consider it stable. With that in mind, we recommend that you use the latest development code, because it generally contains more features and fewer bugs than the "official" releases." I wasn't able to convince the core developers that this is important, so I thought I'd solicit some opinions here: Should newforms security fixes be posted to django-announce?

This is exactly what happens in my code so this should solve my problem.
Thought i mention it here so other people can benefit from it.

In a Change Manipulator view we should always call
manipulator.do_html2python(new_data) before we check for errors. If
there are errors, FK and M2M field values will not be preserved when the
form reloads with the errors. Only data that is not populated from
external relationships will be maintained
BAD example:
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
if not errors:
manipulator.do_html2python(new_data) #BAD!!!
manipulator.save(new_data)
# Do a post-after-redirect so that reload works, etc.
return HttpResponseRedirect("/places/edit/%i/" % place.id)
GOOD example:
if request.POST:
new_data = request.POST.copy()
errors = manipulator.get_validation_errors(new_data)
manipulator.do_html2python(new_data) #GOOD!!!
if not errors:
manipulator.save(new_data)
# Do a post-after-redirect so that reload works, etc.
return HttpResponseRedirect("/places/edit/%i/" % place.id)

custom validator or other way to avoid double bed bookings
Hi, my app is used to manage patients of a ward in a hospital. This ward has a number of beds available. A patient has a room id referring to the room/bed where he's laying. Now i would want to avoid being able to select a bed that is already in use. I thought of using my own validator. So ideally i would like to keep all fields and just change the room field instead of defining them all. I didn't find a clear way of only changing one field without specifying them all. I hacked it by first looking up the index of the field in the fields list and replacing it with my own version: fields[index] = forms.SelectField(field_name="room", choices = room_choices, validator_list=[room_validator]) room_choices is simply a list of all the rooms and room_validator is my room validator. The problem i'm having with this approach is that the current room isn't preselected in the dropdown list when i change the patient data. Could be expected when you make your own. How can i specify a selected room in forms.SelectField or is there another way to make sure a user can't assign a bed that is already in use?
