Template Inheritance - best solution

[eeyore]

I am working on an app that currently has two main base templates.

What I would like to do is to avoid having multiple base templates and
having duplicated code withing my templates.

For example I might have navigation include in the base template, but
on the login screen there is no navigation.

What's the most flexible and efficient way to accomplish this?

Re: SOAPLIB issue with django upgrade

[Wombatpm]

For the record.  SOAPLIB 0.8.1 has a bug in generating the WSDL file
for Arrays.

> 
> -
>

>

the type declaration should be type="xs:string"


The unicode issue is being raised by lxml inside of soaplib.  Calls
from .NET clients include an xml declaration and an encoding type.
Calls from SOAPUI do not include the xml declaration.  Under python
2.6 strings are unicode so lxml raises the error.

Question to django world:  Where is the best place to fix this bug?
lxml where they punted on unicode strings effectively?  Soaplib which
should sanitize its calls?  or Django since it knows what it received
over the intertubes and is in the best position to create the string
correctly?

Perhaps if you put a few more words around what it is you are trying to do
someone might be able to offer useful help.  This code looks quite odd to
me.  You generally don't want to take values from form.data (which will not
have been normalized) but rather validate the form and then take values from
form.cleaned_data (which will be both validated and normalized).   Doing
nothing with what you've got other than displaying the form (again?) also
seems a bit odd.

You did not do the work required to access a template variable passed to
your tag.  Your tag gets a string, the name of the variable in the context,
not the variable itself.  This is covered in the doc here:

http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#passing-template-variables-to-the-tag

Yes, see:

http://docs.djangoproject.com/en/dev/howto/custom-template-tags/#shortcut-for-simple-tags

>From a brief glance it looks to me like what you are writing could easily be
just a simple tag, which is much easier to write and frees you from having
to resolve the variables (the step you have missed) and also check the
required number of arguments, etc.

Do read through to the end of that page on custom template tags.  Inclusion
tags may be useful for you here.

create a link from an object - template tag or?

[MIL]

Hi :o)

I am attempting to create a simpler way to create my links. and I
developed this template tag:


class LinkNode(Node):
def __init__(self, object):
self.object = object

def render(self, context):
model_name = self.object.get_model_name()
linktext = self.object.get_linktext()
url = self.object.get_absolute_url()
if model_name and linktext and url:
return '%s' % (url, 
model_name.lower(),
linktext)
return ''

@register.tag
def create_a_link(parser, token):
# {% create_a_link to object %}
bits = token.contents.split()
if len(bits) != 3:
raise TemplateSyntaxError, "create_a_link tag takes exactly 
three
arguments"
if bits[1] != 'to':
raise TemplateSyntaxError, "second argument to create_a_link tag
must be 'to'"
return LinkNode(bits[2],)


But I get this error message:
TemplateSyntaxError at /
Caught an exception while rendering: 'unicode' object has no attribute
'get_model_name'

What am I doing wrong

Is there a simpler and better way to do this job?

I would also like to develop something that can make it simpler to
create tables and lists, but that later on.

Thank you :o)

Sounds like you have another archive_week function defined (or imported)
after your import of Django's function.  This other one takes only three
arguments and does not include queryset among them.

It's a reasonable candidate. It's unique by definition. I can't think
of any obvious reason the session key wouldn't work as a temp
directory name.

Yes. It's call cron :-)

Sessions don't expire on their own. They are evaluated as expired when
you check them against the current date. Django ships with a cleanup
method (manage.py cleanup) that you can run once a day as a cron to
find and purge stale session data from the database. This command
won't work out of the box if you're using the file backend for
sessions, but it won't be too hard to write an analogous management
command.

Yours.

subprocess.Popen in django production - are file descriptors closed?

[aaron smith]

Hey All, quick question.

I have a small snippet of code that runs a ruby script, which I read
the stdout when it's done. But, I'm not getting the stdout when it's
in django production.

Here's my python snippet:

def generate_license(paymentForm,dsaPrivFile):
name = paymentForm.cleaned_data['firstname'] + " " +
paymentForm.cleaned_data['lastname']
product = paymentForm.cleaned_data['product_code']
command = "/usr/bin/ruby licensing/genlicense.rb " + "'" +
dsaPrivFile + "'" + " " + product + " '"+name+"'"
process = subprocess.Popen(command,stdout=subprocess.PIPE,shell=True)
stdout_value = process.communicate()[0]
print process.stdout.read()
print stdout_value
return stdout_value

I have a couple prints in there just for testing in debug. My question
is how to get this to behave normally in django production
environment. I've tried a couple different things with opening tmp
files and using that for stdout for subprocess. But no luck. Any help
is much appreciated.

Thanks

Serve dynamic info pages in the admin tool

[Wim De Houwer]

Hi All,

I'm new to this list and maybe i'm asking a question which might have 
passed here already, but i couldn't find a answer on the archives.

I have a Model which holds a list of people :

This is the most important info out of that model:

class Members(models.Model):
MemberId = models.AutoField(primary_key=True)
MemberFirstName = 
models.CharField(blank=True,max_length=200,verbose_name='Voornaam')
MemberLastName = 
models.CharField(blank=True,max_length=200,verbose_name='Familienaam')
MemberStreet = 
models.CharField(blank=True,max_length=200,verbose_name='Straat')
MemberHouseNumber = 
models.CharField(blank=True,max_length=6,verbose_name='Huisnummer')
MemberBusNumber = models.SmallIntegerField(blank=True,verbose_name='Bus')
MemberPostalCode = 
models.SmallIntegerField(blank=True,verbose_name='Postcode')
MemberTown = 
models.CharField(blank=True,max_length=200,verbose_name='Stad/Gemeente')
MemberBirthday = 
models.DateField(verbose_name='Geboortedatum',default=datetime.date.today)
MemberAssociation = 
models.CharField(max_length=10,choices=FederationChoices,blank=True,null=True,verbose_name='Aangesloten
 Federatie')
MemberOfficialRegNumber = 
models.CharField(blank=True,max_length=20,verbose_name='VVB/VLM 
Aansluitingsnummer')

I want to serve to my staff members a page with some statistics from the 
data in this model like:
- How many people between 0 and 18 years old
- How many people within a specific Postal Code
- How many people with active subscriptions to the official volleybal 
federation

And combinations of the above.

This still is not really a problem, the hard part is that I want to 
integrate that into a page shown in the admin interface as a link or 
semi static page.

I know it's abusing the admin a little, but I presume it must be possible.

Thanks for your answer !!

Wim

MultiWidget Help

[Rob Broadhead]

I have a MultiWidget class shown below that combines a selec and
textfield widget. I want to return only the value of the textinput
though. I have done a lot of Googling and have the compress-decompress
methods competely confused in my head so my question is "How does one
create a multiwidget and return only the value from one of the widgets
it contains?"

Any help will be greatly appreciated,
Rob

class Suggester(widgets.MultiWidget):
CHANGE_CODE = """
... nothing useful here...

widget_list = (widgets.TextInput(attrs=attrs),widgets.Select
(choices=TAG_LIST))
super(Suggester, self).__init__(widget_list,attrs)

archive_week argument error

[Eric Montgomery]

I'm experiencing a really odd problem with the archive_week generic
view.

I am trying to call it like I do a bunch of other generic views
throughout my app, but archive_week seem to not like the arguments I'm
giving it.
Here is my code:

return archive_week(request,
year = year,
week = week,
queryset = Submission.objects.all(),
date_field = 'pub_date',
template_object_name = 'submission')

I'm getting a TypeError with the exception "archive_week() got an
unexpected keyword argument 'queryset'" with that code. I looked at
the source code of the generic views and thought that maybe since the
request, year, week, queryset, date_field arguments were not keyword
args, I should simplify the call to:

return archive_week(request,
year,
week,
Submission.objects.all(),
'pub_date',
template_object_name = 'submission')

However, this gives me a TypeError with the exception 'archive_week()
takes exactly 3 non-keyword arguments (5 given)".

The real kicker is that if I go change the name of the function in the
django source code (I renamed it to archive_wk) and change the import
and function call to match, both of the above examples work perfectly.

Is there some argument checking going that is tied to the
"archive_week" name that doesn't happen when I change the name to
"archive_wk"?

Thanks,
Eric

Re: Session problem?

[David]

Hi Angel,

Thanks so much for your prompt reply. Appreciated.

Reading your script, I can see that you use my_id=request.user.id. In
my code I used username = request.user.username. (notice my commented
code? I just tested request.user.id. The problem exists.)  So there is
no major difference as it has the same logic. However, the problem
loops back to my original question: why can not request.user give the
correct logined user? Why one session seems to over-write the other?

When I wrote my scripts, I used request.user first. As it could not
give me a correct user's name, I turned to session. However, session
had the same problem.

I read online DjangoBook again and again, trying to find what I missed
or what I did wrong. I spent much time on googling online. However I
can not find what caused this problem.

Re: Session problem?

[Angel Cruz]

Your implementation is dependent upon session cookies, and I am sure you
have a good reason for it.  I am as stomped as you are why that is (unless
you are like me, who confuses 127.0.0.1:8080 w/ localhost as I open multiple
browsers in testing my site...each will have different session cookies).

My implementation is dependent more on the user id being passed in from the
login page if a user is not logged in and just passing the User object into
the template:

my view.py has:
---
@login_required
def index(request):
.
.
.
 if request.user.is_authenticated():
 my_id=request.user.id
 user = get_object_or_404(User, id=my_id)

 context = {'my_auth_user': user, blah blah }
.
.
.
 return render_to_response('registration/detail.html',
  context,
  context_instance =
RequestContext(request))

my template ('registration/detail.html') has:
-
{{ my_auth_user.username}}
{{ my_auth_user.first_name}}
{{ my_auth_user.last_name}}
{{ my_auth_user.email}}

This ensures the the User object for that id belongs to is being called to
get the username and other information.

Of course, you can pass into the template the cookies and session id stuff
by placing them in the context variable.

Remove leading and trailing whitespaces in TinyMCE text area.

[Sonal Breed]

Hi all,

I have a textfield which I am rendering as a TinyMCE widget. So the
value entered in this text field is passed in html format to the
server. I want to trim leading and trailing whitespaces from the
value. Since the value sent back is always in following format:
 some value , even though I use strip/rstrip/lstrip functions,
they are of no use.
I am currently trying to modify render(self, name, value, attrs=None):
function in tinymce/widgets.py as there the function call is directed.
Something like this:

def render(self, name, value, attrs=None):
if value is None: value = ''
value = smart_unicode(value)
value = value.strip()
final_attrs = self.build_attrs(attrs)
final_attrs['name'] = name
assert 'id' in final_attrs, "TinyMCE widget attributes must
contain 'id'"

mce_config = mygo.tinymce.settings.DEFAULT_CONFIG.copy()
mce_config.update(get_language_config(self.content_language))
if mygo.tinymce.settings.USE_FILEBROWSER:
mce_config['file_browser_callback'] = "djangoFileBrowser"
mce_config.update(self.mce_attrs)
mce_config['mode'] = 'exact'
mce_config['elements'] = final_attrs['id']
mce_config['strict_loading_mode'] = 1
mce_json = simplejson.dumps(mce_config)


html = [u'%s' % (flatatt(final_attrs),
escape(value))]
if mygo.tinymce.settings.USE_COMPRESSOR:
compressor_config = {
'plugins': mce_config.get('plugins', ''),
'themes': mce_config.get('theme', 'advanced'),
'languages': mce_config.get('language', ''),
'diskcache': True,
'debug': False,
}
compressor_json = simplejson.dumps(compressor_config)
html.append(u'tinyMCE_GZ.init(%s)' % compressor_json)
html.append(u'tinyMCE.init(%s)' % mce_json)

return mark_safe(u'\n'.join(html))


But somehow it is not getting reflected. When I replaced value with
some hard string like 'Sonal' and use .strip(), then it works, so I
guessing the type of value variable here. Did anybody have this
problem??

Joost, Can you please tell me what I am doing wrong here?

Thanks in advance,

Sincerely,
Sonal.

Base your admin class on the UserAdmin class. Inherit whatever you need from
it and override whatever you want to customize yourself.

Good point.  If the description had used the word "cache" I might have even
found it when I was searching for a workaround.

Re: Many-to-many column admin interface

[Sven Richter]

Yea, i thought about that, but for me this seems like an ugly workaround.
Dont misunderstand me, i dont know enough about django and its database
internals, but why should i use a third model for something i can access
directly?

The solution i posted above was exactly what i was looking for and what
seems logic to me, but i could of course be wrong too.

Sven

Re: Session problem?

[David]

Hi Angel,

Thanks for your reply. I just tested with decorator @login_required.
The problem still exists.

Following is script for my homepage.

# this is the homepage
@login_required
def my_view(request):
if request.session.test_cookie_worked():
#username = request.user.username
if request.user.is_authenticated():
username = request.session['username']
#username = request.user.username
return render_to_response('my_view.html',
{'username':username})
else:
return HttpResponse("Please enable cookies and try again.")


Neither request.session nor request.user can give a correct user's
name all the time. In my login(request) I have

 if request.method == "POST" :
username = request.POST['username']
password = request.POST['password']

user = authenticate(username=username, password=password)
if user is not None:
if user.is_active:

request.session['password'] = password
request.session['username'] = username
request.session.set_expiry(0)

login(request, user)


So, why can not session bind username to it? And why can not
request.user give the correct logined user? it seems to me that
sessions are interweaved when two users login at the same time. Or one
session over-writes the other? Checking session keys in session table,
I can see that each session key is unique.

Thanks again for your reply. I appreciate it. Do you have more ideas
where I missed?

Re: Session problem?

How does your view.py look like?

I use the decorator @login_required right before each def that I want to
ensure is viewable only to the logged-in user.

Re: Many-to-many column admin interface

[Sven Richter]

But i wonder how this would help me further.
In the End it doesnt matter for me on which model i define the M2M relation.
But i need to access the M2M Table from both models, at least in the view or
in the template if not in the admin interface.

I am having a hard time finding out how to achieve that.

Any Ideas?

Session problem?

[David]

hello Django community,

I met this problem and can not find a solution. I wonder if any people
has met this problem before? Can anybody give a clue or hint how to
fix it?

For my project, I have enabled sessions and I use
contrib.auth.models.User. If one user logins into his/her account, all
is perfect. However, if another user logins (no matter if it is from
the same computer or from another computer), then the two users sees
each other's information in their own account.

I also found that

(1.) request.user.username gives another logined user's name instead
of this one (the correct one) even though I called
request.user.is_authenticated().

(2.)  request.session['username']  does not give the username that I
assigned it earlier.

(3.) Old session is still there even though a user log-out correctly,
closes the browser (IE) and then opens another browser (Firefox).

I have put "SESSION_EXPIRE_AT_BROWSER_CLOSE = True" in settings
already. In my code I have request.session.set_expiry(0).

Checking my session table, I can see that the "expire date" for
sessions are in two weeks. Does this mean that
"SESSION_EXPIRE_AT_BROWSER_CLOSE = True" did not work?

Any suggestions?

Thanks so much.

Re: Initial value in admin form based on url parameter

[bhomnick]

Actually figured it out by looking at the modeladmin source.  If you
have, for instance, an object called Payment with a foreign key User,
you can just go the url payment/add?user= and the user select
field will default to that user.

Hi Mirat,

You can user, user.is_authenticated() method to check whether the user
is
authenticated or not.

Re: Many-to-many column admin interface

[Sven Richter]

Ah, and google does help or at least django_snippets.
I found the solution here:
http://www.djangosnippets.org/snippets/1295

The trick is to create a column in both models and in one with the option to
not syncdb.
Its really simple, just 6 lines at all.


Greetings and a nice Weekend

Erm... {% if user.is_authenticated %}{%  
endif %}?

Of course you'd also have to check that the current user is the owner  
of the page.

you could also build a custom templatetag to handle all that, FWIW.

Re: Many-to-many column admin interface

[patrickk]

I could be mistaken ... but why not using a third model.

C(models.model):
   a = models.ForeignKey('A')
   b = models.ForeignKey('B')

when editing either A or B, you could use C as inlines.

regards,
patrick

Finally, I have some debugging output! I didn't think I needed this

Temporary session directory

[John Barham]

I'd like to store per-session files so need a way to reliably create a
per-session temp directory.  Is it reasonable to use the
session.session_key to generate a unique name?

Also, is there a way to have Django automatically run some code to
cleanup my session once it has expired?  Or do I have to resort to
cron?  (I'm using the file-based session backend.)

Thanks,

  John

Custom User Model and the Django Admin Site

[Bryan]

Hi All,

Just a quick query to see if anyone has any ideas on this one.

I have a model in my application that inherits from the django User
model.  In the admin site, without any extra configuration (just using
ModelAdmin), I get a standard edit form with the custom model's fields
as well as the django User fields.

The problem that I have is that a "change password" link is generated
(which is desirable), but the url is not routed properly - resulting
in an error.  The url looks like "/CustomModel/id/password".  Digging
around in /contrib/auth/admin.py (working off of memory :P) it looks
like UserAdmin does some voodu magic to hijack the request and execute
some "view logic" in the case of a url that looks like a password
change request.

It looks something like this (psuedocode):

 // inside of __call__ method
 if url is a password url:
  return result of change password method call on UserAdmin
object
 else
  delegate to base class

I can get the change password form to work by simply using the
UserAdmin class, but it explicitly defined the fieldsets (which of
course don't include my custom fields).  As a side note, might it be
possible to define the fieldsets in __init__?  I was under the
impression that the fieldsets are metadata for the class not the
instance.  Even if this is the case I believe I would still have to
duplicate the User model fieldsets.

Multiple inheritance doesn't seem to work (not surprisingly), and I
wouldn't be thrilled about that approach anyway.

So, my "solution" was to duplicate this logic in my admin class, and
it works just fine now.  Anyone have any better ideas?

Re: Execute code after sending a http response?

You'll have to set something in a table and run a cron to send it

with it.

One of the tables needed for admin does not exist.  It appears you did
not run python manage.py syncdb after adding admin to your
INSTALLED_APPS.  You need to run syncdb after adding apps so that
their tables will be created.

Admin inlines onetoone related object not saved

[Jean Stebens]

Hi there,

I have the following models:

class A(models.Model):
id = models.AutoField(primary_key=True)

class B(models.Model):
mya = models.OneToOneField(A, primary_key=True)
text = models.TextField(default='Init')

In admin interface, I have used an inline to include B when
changing/adding an A. Adding/Changing an A without touching the B inline
results in A beeing saved, but not B. Changing the textfield from B into
sth other than default and it works, but I want to keep the default as
is - Is there any solution for this?

Thanks!
Jean

It is not correct to say that Django does not support that format.
That format is not one that is accepted by default as an input format
for the DateTimeField form field.  However, you can easily specify
your own input_formats and then your form will accept that format:

http://docs.djangoproject.com/en/dev/ref/forms/fields/#datetimefield

It does not make sense to say you want to store that format in MySQL.
The value stored in MySQL is a DATETIME, independent of any particular
format.  Since you are using Django you do not need to be concerned
with what format is used when Django stores the data to MySQL or
retrieves it from MySQL.  What you need to adjust is the input formats
your field accepts, and the output format used by your form field's
widget to display existing data (see the format parameter here, for
example: 
http://docs.djangoproject.com/en/dev/ref/forms/widgets/#django.forms.DateTimeInput)

Re: show user and date in change_list

[Sandra Django]

Thank's Alex, but it don't seem the problem, because I tested with another
method name "author" and "pub_date", and returns (None) too. Why?

Yes, unless you are running an SMTP server on the same machine you need to
set EMAIL_HOST to point to one, and set whatever other EMAIL_ settings are
required to use the server you point to:

'%d-%m-%Y' format for DateTimefield in django

[Jigar]

Hi All,

I am trying to add the '%d-%m-%Y' format in DateTimefield. As django
does not support this format so when I add different date formats, it
gives "invalid date/time" error in django console.This error occurs
because the form is not valid(form.is_valid()) as above mentioned date
format is not supported by django. Also, I want to store this date in
the mysql database.

I have tried following:
I have converted the string (date entered in html page) in to the date
object which is in '%d-%m-%Y' in views.py before form_is_valid()
called. Now I am not able to set the attribute value for a particular
field so that form.is_valid() gets the correct date object.

Any Ideas for this issue ?

Python's unicode function must return a unicode object.  If your __unicode__
implementation does not return a unicode object then Python coerces it to
unicode.  But there are only a limited number of types that Python can
coerce to unicode (strings and buffers, or so the message implies).  So if
you return neither a unicode object, nor a string or buffer, then you get
this error.

There are places where ugettext_lazy cannot be used.  This would appear to
be one of them.

Your urlpattern for entry_archive_month is:

url(r'^(?P\d{4})/(?P\d{2})/ ,
date_based.archive_month,
dict(entry_info_dict, month_format='%m'),
name='entry_archive_month'),

That (since you specified {2} after the \d where you capture the month)
requires exactly 2 digits in the month.  Per the error message you only have
one digit in the month, so no reverse can be found for the kwargs you have
specified.

I'd leave Apache running under the system account - that's how it is
by default, and I would think that there are good reasons for it.

Try using python to impersonate another user to launch foxit/adobe
reader in another user account context, or the easier way is to
leverage the 'runas' command to run an app under another user account.

Re: 500 error when DEBUG = False but not True

Thanks Jarek and Daniel. I saw that message in the traceback but
thought that a 500 page was only required to show something sensible
to the end user merely saying there had been an error.

I have put in a 500.html template and I have configured my email
address in the settings.py to a valid email address. The system is
configured to deliver mail. But it does not appear to be sending any
mail nor am I getting anything in the apache error_log anymore. I just
get my 500.html template displayed.

So it seems I still have no info on what the real problem is. Do I
have to give django an smtp server address or anything else to enable
it to report errors and tracebacks somewhere?

The stacktrace shows that the 500.html template is missing [1], so go
ahead and create one. You should also make sure that you have
configured the admin email address and settings for sending mail
correctly, so Django can send you a traceback by mail when DEBUG =
False

Re: Generating slugs

[esatterwh...@wi.rr.com]

You might look in to the Autoslug field in django command extensions
http://code.google.com/p/django-command-extensions/

the autoslug field is never displayed on a form, but you specify which
fields from which to create the slug from. so you can do it how ever
you want. I've found it very helpful.

You do not have 500.html template and this error hides actual source  
of the error. See 
http://docs.djangoproject.com/en/dev/topics/http/views/#the-500-server-error-view
 
.

When DEBUG == True the 500 errors are processed by debugging view.

As Daniel said, you could use a queueing service or a database table
to store the fact that an email should be sent later.

Wouldn't you want to show the user an error message if sending the email failed?

Btw, the time needed to send an email is not so long normally. I think
the benefits (possibility of showing an error message, less
complexity) outweigh the downsides (a bit longer processing time)

Help with the url template tags

[Phil]

Guys,

I have this error in my template when rendering my view: "Caught an
exception while rendering: Reverse for 'entry_archive_month' with
arguments '()' and keyword arguments '{'month': 8, 'year': 2009}' not
found."

I've starred at my code for too long and I can't see where the problem
lies. I'm sure it's a stupid and silly error, but I've look too much
at my code and can't seem to figure out what is happening.

Basically, the tag {% url blog:entry_archive_month
year=date.year,month=date.month %} is throwing the 'reverse for
'entry_archive_month not found'.
I've tried with args instead of kwargs (i.e.: {% url
blog:entry_archive_monthdate.year,date.month %} but without success

In another template, I have {% url blog:entry_archive_year
year=year.year %} and it works perfectly fine (and even the 'args'
version, which seems to indicate that this is some serious flaw in my
understanding of url namespace and reversing in django).

I'm just baffled and to tired to see clearly what is my stupipd
mistake.

Here is the traceback: http://dpaste.com/86470/

Here is some part of my code (the two urls.py): http://dpaste.com/hold/86487/

Can anyone help me with this one ?

Yes, but not in view function, you can use signals. See

Custom form validation request or user-based

[Enrico Sartorello]

Hi,
i'm developing a Django application where i need to differentiate the
validation of an admin-site model form between different users: some user
must respect some particular restrictions (imposed via "clean_*" methods)
while others should do what they want without them.

The problem arises because during form validation i cannot access any
request object (so i can't build a permission-based criteria), and checking
everything in other places (like Model_admin.save_model() method or with
signals) can't do the job because there i can't raise form's validation
errors.

I've searched on the net but seems i cannot find any solution for that
problem.

Any hints?

Thanks for the attention

Execute code after sending a http response?

[Shadow]

Hi,

Is it possible to execute code after sending the actual http response?

For my website, users can optionally give an email address, and if
they do, the site sends a confirmation email. But I was thinking it's
more logical to spend time sending the email after the signup
confirmation page is sent to the user. Since sending the email doesn't
affect the http reponse at all?

Is this possible?

cheers

Not directly - once you've returned from your view, that's it.

One possibility though is not to do the email sending within the view.
Instead, the view simply sets an attribute in a table somewhere to say
that an email needs to be sent to a certain user. Then you have a cron
job that runs regularly, extracts the users with the flag set, and
sends the email.

You could perhaps achieve the same thing using message queues - have
your view send a message to the queue, and a separate listener which
receives the message and sends the mail.

Re: Many-to-many column admin interface

At least with Django 1.0.x, the admin interface does not support
many-to-many relationships on inlines -- it will always return an
error like the one you got above.  Indeed, the message is technically
accurate, because m2m relationships get implemented as a separate
table, so there is no direct relationship between the two.
InlineModelAdmin works great for one-to-many but not for many-to-many.

I'd also be interested in solutions to this, not having found anything
in a bunch of Google searches.  The alternative I'm planning on is
having to hand-code some views, forms, and templates that let me do
the right thing -- not a huge amount of work, but having admin do it
for us would be way cool.

variable as a field name in a template?

[Unnamed_Hero]

Is it possible provide a variable for a field name in a template?

A have a database with a corporations. I want to create some kind of a
report generator. Users can choose necessary fields, specify some
filters and get a result.

I've created a form with checkboxes near field name, have created a
form with filters, have created a queryset from user request. My
problem that I can't understand how can I show only user selected
fields in a template. Can you show me the right way?

Creating a custom widget

[nbv4]

I have a Flight model which has a foreignkey field that relates to a
route object. I created a custom field to go with my FlightForm that
allows me to enter a simple string, which is then, via the clean()
method, constructed into a Route object that is attached to the
flight. This works fine, but what I'm trying to do now is have it so
when I create a FlightForm formset, my route field is rendered as a
textbox with the __unicode__ representation, instead of just the
primary key as it is now. How can I do this? I understand I need to be
making a custom widget not a custom field to do this, right? This is
what I have so far:

###

class RouteWidget(widgets.TextInput):
def render(self, name, value, attrs=None):
return mark_safe("")

###

The problem is that the "value" value is never anything other than
None. Even though the form is being populated via a formset. What am I
missing here? The name attribute seems to be working...

Re: Admin search error (using auto complete FK widget)

[mr.kschan]

Hi,

There is solution to use Jannis's widget with Django 1.1.

Please read the blog post's comment by Christian Abbott June 24, 2009.

The __call__ is deprecated in Django1.1 and you could better update
the code to use get_urls() instead. =]

I just tried and it works ^^

ugettext() and ugettext_lazy() - error and difference

[Léon Dignòn]

Hi,

I don't exactly understand the difference between ugettext() and
ugettext_lazy(). I read the documentation and I've read that
ugettext_lazy translates a string on access. Sounds more efficient.
But why do I get this error on that code?

from django.db import models
from django.utils.translation import ugettext_lazy as _

class Country(models.Model):
name   = models.CharField(max_length=256, unique=True)
name_iso_2 = models.CharField(max_length=2,   unique=True,
help_text='http://de.wikipedia.org/wiki/ISO-3166-1-Kodierliste')
name_iso_3 = models.CharField(max_length=3,   unique=True,
help_text='http://de.wikipedia.org/wiki/ISO-3166-1-Kodierliste')

def __unicode__(self):
return _(self.name)



Exception Type: TemplateSyntaxError at /admin/skins/country/
Exception Value: Caught an exception while rendering: coercing to
Unicode: need string or buffer, __proxy__ found

I was facing the same problem. Django 1.1 with py26

But I think if u try fallback to Django 1.0.2 or 1.0.3 , the problem
will not exist.

ticket #11678 http://code.djangoproject.com/ticket/11678
