Re: template inheritance

[James Matthews]

Not always sometimes you want to show some template code (You have a blog
about web dev) and sometimes you want to nest some code.

Re: Django Development Process

[steve]

You'll find the perfect way for you to approach each stage of it I'm
sure.

I'm always into figuring out Use Cases the very first thing.  I like
to establish at least 4 or 5 different major tasks that a user would
need/want to do, and then get these out of my head into a concrete
form  (currently this means the Treepad outliner in a "use case"
branch).

This first step naturally, without too much mental effort, steers me
next into making decisions about what screens I will need, and what
models I will need to read/write in each of those screens.
 
--
So my first step is 1.) sketching what I need highlevel-wise,

2. ) Then deciding what those urls will be, going into urls.py to
write three or four mappings (for only read operation functions such
as getScores or whatever, i'll worry later about writing the write
operations when I start writing the html forms in the views )

3. ) And then start writing the models I know I will need. When I'm
finished with about 80% of the models I know I will need, I use the
Python shell to check things. When I'm satisfied that all of the
related tables give me the right result on the shell console by
manually running model.objects.all(), etc.., the next step

4. ) I go into views.py and write three or four functions that do some
reading

5.) Then the views - write the tags for retrieving database results.

.. and then I view a Djangocon speaker on youtube and realize how much
I have to learn when it comes to performance, and all of the different
areas to look at:
  check out: http://www.youtube.com/watch?v=D-4UN4MkSyI

  Seriously, not that we will all have sites that demand that type of
bandwidth, but it is definitely educational.

Putting pieces back together again

[Mark Jones]

I have some fields on my page that have more than one attribute for
simplification, lets say two attributes

answer = {'txt':'something', 'allowblank':0}

laid out on the page as:
{% for answer in quiz_question.answers %}
  
  
{% endfor %}

the first is pulled from an input field, and if !allowblank, needs to
have some text.

I write some OnSubmit() javascript on my page to check this field, and
if it is blank, check the allowblank attribute in the following hidden
field to see if this is OK.  If is isn't ok, I ask the user "you sure
you wanna leave this field blank?"  If the user says "YES, I want to
leave it blank, the JS changes allowblank to 1 and we submit the form.

If the backend gets the form and the field is blank, but the
allowblank is true, then I know the user said OK, no problem, I let it
be blank, otherwise I validate it on the server side (in case they use
noscript like I do) and if allowblank=0 and the field is blank, I send
the form back to them with a checkbox like this

{% for answer in question.answers %}
  
   I
really want to leave this field blank
{% endfor %}

My problem comes about because a nice list of dict objects has been
broken apart by the html form and needs to be reassembled.  While I
can do this like so:

  for i in range(len(qqanswers)-1,0, -1):
  qqanswers[i] = {'txt':answers[i], 'allowblank':int
(allowblank[i])}
  if answers[i] == '' and allowblank[i]:
  del qqanswers[i]

I don't like how ugly this looks.  I tried changing the names of the
input objects to:

answers.txt and answers.allowblank, but that didn't work, I got POST
lists back that were names answers.txt and answers.allowblank that
looked like:



of course all of this ignores the fact that checkboxes that aren't
checked aren't sent back to the server anyway which is where the need
for a more elegant solution comes from in the first place..

Is there a nice elegant way to solve this, or does it just have to be
done the way I've done it..

My general approach is:

URLs first, which helps me think through the various pages users will
interact with.
Roughly sketch those pages, think about features and models needed for
reasonable normalization.
Code models
Implement views.
Implement templates.
Factor out template tags.

Okay I think I figured it out. I studied the existing filters a bit.
You can test the input value to your filter function with "isinstance
(value, SafeData)". If so, you don't need to escape it.

You need to use a more recent version of Django. Safestring was
introduced after 0.96.  See:

http://code.djangoproject.com/browser/django/trunk/django/utils

vs.

Django Development Process

[AlexiPoliski]

This is a call for opinion based on experience :)

I'm in the process of creating the models for my very first Django
application in my very first project. I have read the book up to and
including chapter 7 (everything i need to know to get started).

Naturally I have the design of the system I want fairly well figured
out, and have moved on to do most of the work for the models
(primarily as far as the database is concerned).

Currently I am wondering what the next stages are going to be, and I'm
not too sure what I would like to do as a matter of process. I
remember reading a section in the book highlighting that you could do
it either way, depending perhaps on your own programming preference or
the situation.

I've given it some thought, but I'll keep my current inclination for
what I would prefer to myself for now; I'm still undecided anyway. If
the decision is 50/50 and absolutely depends on what you are
developing, then let me know what cases illustrate the deciding
factors. I would imagine that experienced developers would have a
predominant preference by now and THAT is what I would really like to
hear about :)

---
tldr;
What I would like to ask is, from more experienced Django developers,
what way do you prefer to create your applications? Models then views
then templates? Models then templates then views? Or models then views
AND templates concurrently.


If there has been a discussion that addresses this subject already
then I would appreciate a link to that just as much.

Thank you,

POST still occurs after HttpResponseRedirect

[stryderjzw]

Hi,

Here's part of my code:

class NewAssignmentFormPreview(FormPreview):

def done(self, request, form):
assignment = form.save(commit=False)
assignment.save()

...

return HttpResponseRedirect(assignment.get_absolute_url())


I do an HttpResponseRedirect to go to the assignment page after it's
been created.

However, when I do a refresh on that page, it still asks me if I want
to submit POST data and an additional assignment is created. I thought
HttpResponseRedirect is suppose to prevent that.

Any ideas?

Thanks!
Justin

Hi Karen -

I'm using 1.0.  I took out the class admin and added an admin.py file
as follows:


from learn.testimonials.models import Testimonial
from django.contrib import admin

admin.site.register(Testimonial)



I restarted apache and got this error:

TemplateSyntaxError at /admin/

Caught an exception while rendering: Tried RandomTesti in module
testimonials.views. Error was: 'module' object has no attribute
'RandomTesti'



RandomTesti is a customized template tag I've created for use in the
site.


Can you help me figure this out? What information do you need?

What version of Django are you using?  The use of max_length instead of
maxlength implies something later than 0.96 but the use of 'class Admin'
implies something before 1.0.  If you are using 1.0 or later 'class Admin'
is not how admin defs are specified any more, see the admin doc for the
current way.

You can leave the mysite off various things. So in the settings file
the INSTALLED_APPS you can put polls instead of mysite.polls. The same
for the import statements. This works because the code is run in the
mysite directory and python automatically finds modules in the
directory the code is running in. In other words python considers the
current working directory to be on the python path.

I am wondering why the tutorial teaches this bad practice when there
is so much emphasis in Django on reusable apps. It seems to me that
teaching the better way of leaving off the site directory requires no
code change but only a documentation change to the tutorial.

Even better would be making the backwards incompatible change of
removing the project directory from the python path to encourage
better practice.

But I also am just learning Django so probably have failed to consider
something important.

can't get a model in the admin

[Bobby Roberts]

here's my model:

from django.db import models

class Testimonial(models.Model):
active=models.IntegerField(max_length=11, blank=False)
testimony=models.CharField(max_length=500)
name=models.CharField(max_length=75)
postdate = models.DateTimeField (auto_now_add=True,
blank=False, db_index=True)
siteid=models.IntegerField(max_length=3,blank=False)

class Admin:
list_display = ('name','active','postdate','siteid')


The user also has perms in the users to have full control over this
model... Why can't it be seen in the admin area?

Decoupling between projects and app in 4-part tutorial.

[dahpgjgamgan]

Hi,

In the 4-part tutorial on Django's main site, there's a lot of advice
on how to decouple apps and projects, but when I look at the import
statements in most of the tutorial's files, it's always "from
projectname.appname import ." - not very decoupled for me. Am
I missing something, is there a good reason why those imports look
like that and not simply "from appname... import ..."?

Thanks!

That's strange, are you succesfully using another component of Django
i18n infrastructure in the same application?. De you have USE_I18N set to
True in the settings file you are using?

Re: Path problem with jsi18n - internationalization

Hi Ramiro,

I'm using the latest development version of Django. Apache web server.
MySqL/Mod_python, all served from same apache on my laptop.

I get a 404 error when I put http:///jsi18n/ into the browser
URL.

template inheritance

[Jo]

While building a website using template inheritance one usually does
the following:

fetch from database
fetch from some more data from database
... << more required computations
then at the end render the template with the fetched data

Without template inheritance one usually does the following:

fetch from database
render this part of the site with this fetched data
fetch some more data from the database
render this other part of the site with the fetched data
...
etc

The first approach is much more elegant and leads to easier to
maintain code. However the user will have to wait till the end of the
fetching (long computations) before any rendering can take place. In
the second approach however the site loads as we are fetching the data
which is more convenient to the user.

Am I correct to assume this? Is there a way to get the best of both
worlds? Maybe using generators? Thank you.

Markdown filter piped into custom filter

[Brian Neal]

I wrote a filter that searches for patterns in text and replaces them
with  tags:

{{ comment.text|smilify }}

It does various silly things like replace :-) with an actual smiley
face image. Seems to work great.

When I combine it with the markdown filter, like this:

{{ comment.text|markdown:"safe"|smilify }}

It seems to escape the HTML that the markdown filter produces. In
other words if my comment text is ":-)" then the output I get (when
viewing the raw HTML source of the document) is p/p

Is it not possible to use the markdown filter like this? Or is the
markdown filter supposed to mark its output as safe and my filter is
incorrectly escaping it?

The source for my filter is here:

http://dpaste.com/107803/

What version of Django are you using?, which web server? what deployment
method? Does the web server show a 404 error in its logs when the /jsi18n/
URL is accessed from the browser? What happens if you manually open with
your browser the http:///jsi18n/ URL?.

I'm having a problem accessing Javascript Translation catalog whilst

}

(r'^jsi18n/$', 'django.views.i18n.javascript_catalog', js_info_dict),

However, when I render my template the url to jsi18n generates a "url

Can anyone give me a pointer - I'm sure I'm missing the obvious, but

Re: Where are all the Django jobs?

[Jon Loyens]

Django is starting to gain more traction and I do believe we'll start
to see a bit more of a hockey stick effect on it's adoption over the
coming months.  1.0 being released last year and (at least part-wise)
adoption by the Google AppEngine have both been great PR events for
Django but I'd also argue that Django doesn't have it's Twitter or
BaseCamp yet i.e. a killer application that grabs the mindshare of
startup CTO and CEOs that seemingly make them choose Rails.

At Thinktiv, while we're a professional services company thats
officially platform agnostic, we've chosen Django as our in-house
framework of choice for development.  Django suits the majority of our
customers applications very well (generally interesting presentations
and visualization of structured data and media).  Whenever we've had
customers where we get to influence the framework used, we'll sell
Django into the account.  However, we've had customers comeback and
want to build on Rails for the exact opposite reason from this thread:
lack of people in the Austin area who know Python/Django to take on
the maintenance work after we've done the initial application build.
So it seems like we've got a bit of a chicken/egg problem.

Our organization is going continue to evangelize Django in our
community.  The more that the Django-community sells its virtues in
our various consulting gigs the more opportunity we'll get to use the
framework we love.  To further Malcolm's point above, be a good
programmer first.  Good programmers should be able to pick up (or
already know) multiple platforms, frameworks, languages quickly.
Being a first rate programmer who's technology agnostic will open up a
huge number of opportunities where you'll get to be the person who
influences what gets used in various situations.  It's in those
situations that you'll get to grab your favorite tool: Django.

The views that display comment forms check for this cookie, and use
the information to populate the form. I suppose that could be done as
a context processor.

Hope someone finds that useful,

I can't reproduce this. I've pasted at http://dpaste.com/107769/
a patch against Django forms regression tests that adds a test
demonstrates this works as expected.

Can you try to massage that new test to see if, adding details from
your own case to it, you can reproduce what you are seeing?.

Of course, the only way I could reproduce what you report is
using:

js = 'prototype.js'

forms/widgets media: position of 'class' directive

[Artem Skvira]

Hi all,

I've stumbled upon strange behaviour in django: when declaring form/
widget with class Media, ie.:

class AddressForm(ModelForm):
streetNo = forms.CharField()
...

class Meta:
...

class Media:
js = ('prototype.js', )

I get tons of javascript inclusions rendered to page, for each
character in 'prototype.js', ie.




etc

However, when I move 'class Media:' to the top of the class everything
works ok.
Seems to be a bug to me.

Looking at the traceback, I'm going to guess that the debug tag isn't
handling non-ASCII characters correctly. It doesn't get used too much,
so it may have survived all this time with such a bug in it. A bit
embarassing (for me).

If you open a ticket in Trac and assign it to me (mtredinnick), I'll
look at it in a day or two. Not going to do it right now, since it's
just after midnight here and I'm about to go to sleep.

Regards,
Malcolm

Re: def clean_file works with django server but not with apache

[Alan]

Oops, I found something. I am using apache2 + mod_wsgi and I notice that
instead of using my Fink python ('/sw/bin/python') it's using my mac python
('/usr/bin/python').
I compiled mod_wsgi with fink python, even though I had to put something
like:

WSGIDaemonProcess webapps user=alan group=staff processes=1 threads=16\

 python-path=/sw/lib/python2.5:/sw/lib/python2.5/site-packages

in my httpd.conf file.

Yet, under the light of these news I still have no idea about how to solve
my problem. And maybe now it's a new problem: how to make apache2 + mod_wsgi
use fink python and not system python (for Mac in particular)?

Cheers,
Alan

def clean_file works with django server but not with apache

[Alan]

Hi List,
I have this problem now. It's about a form in my models.py that works as
expected when testing with django server but when testing with apache sever
(all in the same machine, mac osx leopard) it does not work as desired.

class GridJobForm(forms.Form):

file = forms.FileField(help_text="(Mandatory)")

title = forms.CharField(max_length=255, required=False, help_text=
"(Optional)")


def clean_file(self):

file = self.cleaned_data['file']

print file.content_type

if len(file) > gridMaxFileSize * 1024 * 1024: #bytes

raise forms.ValidationError('File size must not exceed %s Mb.' %
gridMaxFileSize)

msg1 = 'File upload must be a valid ZIP/TGZ/BZ2 archive.'

msg2 = 'Could not unzip file.'

msg3 = 'Could not uncompress file.'

msg4 = 'Bad zip file'

#print file.content_type application/x-tar

if file.content_type == 'application/zip':

try:

zip = zipfile.ZipFile(file) #StringIO( file['content'] ) )

except:

raise forms.ValidationError(msg2)

bad_file = zip.testzip()

zip.close()

del zip

if bad_file:

raise forms.ValidationError(msg4)

elif file.content_type in ['application/x-gzip', 'application/x-tar',
'application/octet-stream']:

try:

tarfile.open(fileobj=file) #< problem with apache?

except:

raise forms.ValidationError(msg3)

else:

raise forms.ValidationError(msg1)

return self.cleaned_data['file']

It happens when I submit a tgz file to my apps under apache and the code
enters in "elif file.content_type in ['application/x-gzip'...". When it
"try" 'arfile.open(fileobj=file)' it fails and raises msg3.

I have no idea how to debug this and can't figure out how come it happens. I
tried big and small files (thinking it could be something related
to InMemoryUploadedFile).

I did just another thing: I removed the "try" to see what django debug would
report under apache and I got this:

AttributeError at /ccpngrid/

'NoneType' object has no attribute 'startswith'

Any help would be very appreciated. Many thanks in advance.

Cheers,
Alan

Re: reusable apps and dependencies

Thank you both,
one more thing...
I think it's a very common situation, isn't it?
I mean, if you don't use apps inside your project, you have to manage
the case of different versions of the same app.
But I found only few posts about that, I wonder why?
Do I have to put django-cms in every project? Is it the right choice?

You have the same problem, don't you? How do you do?

Thanks so much!

debug template tag gives me: "'ascii' codec can't encode character"

[Flo Ledermann]

Hi all,

I just bumped into a problem I can't resolve: after adding the {%
debug %} template tag to one of my templates (no other changes), I get
the following error message:

TemplateSyntaxError at /art/

Caught an exception while rendering: 'ascii' codec can't encode
character u'\u2019' in position 19: ordinal not in range(128)

I haven't used the debug tag before, and googleing the error message
didn't bring up anything useful for me, so I am turning to the group
for help. I paste the stack trace and a subset of my settings below.

Thanks in advance for any hints,

Flo Ledermann

Nowhere.

Nope, it's only a keyword argument - nothing else than a litteral
name, really. As Christian already mentioned, the solution here is to
build the name as a string, use this string as a key in a dict, then
pass the dict to filter using the **youdicthere calling convention.
You can read the Python tutorial's part on function arguments and
function calls for more in-depth explanations.

editing multiple records using admin list view

[sateeshk...@gmail.com]

Hi,
  I want to edit multiple records of users ( say selecting the user
records which I want to edit ) and then say if I press
activate button, all the records status should change to 'ACTIVE'.
  To do this kind of thing, is there any simple tweak in admin model
or admin templates ?
  If some one has already done this kind of application, please share
the information.

  Right now with out  any tweaks I can only do single record record
edit going to record detail page, which is not always easy to do.

Thank you,
Sateesh.

I missed the posts. It was a festive time of year, plus have been
exceedingly busy.

If the only thing this web server is going to host is the Django
instances, you are possibly better of not using VirtualHost at all,
but use mod_rewrite to implement virtual hosts. See:

  http://groups.google.com/group/modwsgi/browse_frm/thread/c29dde8fbef68e0b#

They never came back with final configuration which incorporated
static media hosting distinct for each site, but not too much work.
Perhaps post a followup to that thread if you want to work through
static media aliases that are needed so each instance can have its own
separate media files.

Also perhaps use that thread if you want to discuss how to extend that
scheme such that a pool of daemon processes is available and so you
can have dynamic assignment to one of the daemon process groups from
the pool.

Discussion on the mod_wsgi list where that thread is in general better
for me as it then comes in my mail box and don't miss it, where as
just browse here occasionally so don't always pick up posts.

Oh. This is because I'm an idiot and wasn't concentrating. The lines

oa = oa(location=0)
oa.save()

are bogus. "oa" is a queryset, not an object. It should be 

obj = oa[0]
obj.location = 0
obj.save()

Re: django-admin.py not working on Vista

[Cody]

Hi Rex, I came across this same problem and fixed it by editing the
registry like this:

Go to HKEY_CLASSES_ROOT and find .py
Change its (Default) setting to Python.File

Mine was set to py_auto_file when I associated the extension through
Windows.

Anyway, that got django-admin.py running right.

This returned 'QuerySet' object is not callable, so i changed
Article.objects.filter -> Article._default_manager.filter(), still
returning the same problem with the update.

ran into the same objects "'QuerySet' object is not callable", but was
easily fixed with the _default_manager and worked great. Wasn't aware
you could do the .update(), making in chainable. But this worked:

def save(self, *args, **kwargs):

Article._default_manager.filter(location=self.location).exclude
(pk=self.pk).update(location=0)
super(Article,self).save(*args, **kwargs)

Live Contacts Python API Problem

[afrobeard]

Hi,

I was wondering if anyone has taken a look at Live Contacts API at
http://msdn.microsoft.com/en-us/library/bb463989.aspx

I can get through step 1 i.e. Delegated Authentication. An exception
is being raised when urllib2 calls the open function. The nature of
the Error is 403 forbidden exception. Live Contacts API Errors are
defined on http://msdn.microsoft.com/en-us/library/bb463952.aspx

The only relevant post I could on any forum find related to this was:-
1. 
http://social.msdn.microsoft.com/Forums/en-US/wliddev/thread/06cdf66d-2c86-4536-ab8e-af448eec909d/


I'm really grateful for your help. Thanks. The code starts after this
paragraph. WindowsLiveLogin.py itself is availible at Microsoft's
download page http://msdn.microsoft.com/en-us/library/cc287637.aspx


def hotmail_importer_endpoint(request):
from uni.site.profile.views import WindowsLiveLogin

action = request.POST.get('action', None)
wll.setDebug(True)

if not action:
#Show Form or Login Link
url_text = wll.getConsentUrl("Contacts.Invite")
return HttpResponse('''
Click here to initiate authorization
'''%url_text)
else:
fs = {}
for post_var in request.POST:
if post_var in request.POST:
#fs[post_var].value should actually be equal to
request.POST[post_var] as Microsoft implemented it. I just changed the
code in WindowsLiveLogin.py to reflect this fast.
fs[post_var] = request.POST[post_var]
consent_token = wll.processConsent(fs)
#   The consent_token contains delt, reft, skey, exp, offer,
lid
#   Delegation Token
#   Refresh Token
#   session key
#   offer
#   exp
#   lid
token = consent_token
to_signed_64 = lambda x: x < 2**63 and x or x - 2**64
url = 'https://livecontacts.services.live.com/@c...@%s/REST/
LiveContacts/Contacts' % to_signed_64(int(token.getLocationID(), 16))
headers = {'Authorization': 'DelegatedToken dt="%s"' %
urllib.unquote(token.getDelegationToken())}
values = {}
data = urllib.urlencode(values)
req = urllib2.Request(url, data, headers)

I think you may have thrown out the baby with the bathwater there. All
you should have to do is check if the location you retrieve is the same
as the current one and, if so, don't do the update. Like this:

def save(self, *args, **kwargs):
   oa = Article.objects.filter(location=self.location)
   if oa and oa[0] != self:
  oa = oa(location=0)
  oa.save()
   super(Article, self).save(*args, **kwargs)

I've fixed a couple of other problems with your initial code. In
particular, if you're just inserting stuff into the normal save path,
you need to be able to handle the force_update and force_insert
arguments to save. Simplest way (since you don't care what the arguments
are) is to just pass through *args and **kwargs like I've done above.

You could even fine tune this a little bit by using a more specific
queryset (excluding the "self" element) and even using the update()
method. Behold the power of a fully operational Death Star ... er ...
here's a different way of writing it, I mean:

def save(self, *args, **kwargs):
   Article.objects.filter(location=self.location).
  exclude(pk=self.pk).update(location=0)
   super(Article, self).save(*args, **kwargs)

Without testing it, I think that should work correctly even when self.pk
is None (i.e. when you haven't saved for the first time). If not, you
might need to not pass in the exclude() bit if self.pk is None, but test
that out.

Since you don't show the code, and since my crystal ball is in for
repairs this year, it's hard to tell what is wrong with your code. :-)

My guess would be circular imports, which can be solved by not importing
Article directly, but by writing

from stories import models as story_models

def my_signal_handler():
   story_models.Article.objects.filter(...) # etc...

I tend to import models from applications as something like
_models as a habit these days, but you can drop the "as..."
bit if you're only importing that one application model file there.

See http://groups.google.com/group/django-users/msg/a9ab126db3341fd3 for
an explanation I wrote last week about this type of thing.

Still, signals feel like overkill for this situation. You've found the
infinite loop case, so just walk around it in the code. Don't break out
an entirely different shaped hammer.

Regards,
Malcolm

 Just do be aware of one thing. By using a single WSGI script file  
 for
 multiple sites, you loose the ability with mod_wsgi daemon mode to
 touch the WSGI script file and cause a single site to be  
 reloaded. One
 would normally use this as a way of reloading a single site without
 the need to restart the whole of Apache. When sharing the single  
 WSGI
 script file across sites, touching the WSGI script file will  
 restart
 all sites using that WSGI script file. If they share the code  
 this may
 actually be want you want, so not a problem, but worth mentioning.
>>
 In this arrangement, if you did want to reload one site, for  
 example
 because you change its settings file, you would need to use 'ps' to
 identify process(es) in that daemon process group, based on what
 display-name option was set to, and send all those processes in  
 that
 daemon process group a SIGINT using the 'kill' command.  
 Alternatively,
 you would need to setup a background thread which monitored  
 something
 like the distinct settings file for each site and have the process
 itself send a SIGINT to itself. This would be a variation on
 background reloader described in:

Yes sir, after talking with webology, he also pointed out it would end
up in an infinite loop. So i went looking into signals.

So with the help there and here, i moved onto signals.py. By trial and
error, I hope to get going, but have run into a roadblock.

If in the signals.py I put "from stories.models import Article", i
receive ImportError: cannot import name Article. Now my reasoning
behind this maybe wrong as well, so a little explanation there. I want
to import the model so I can do my query on all objects to find the
previous one with the old location...( or I think that is how I should
handle it)

thanks again
