Hi Tom,

Thanks for making this clear!

Now I explicitly save the session and everything works as supposed.

Thanks again!

Re: different admin form if adding a record

[Wim Feijen]

Hi Christian,

I recommend defining your own ModelForm and using that in the admin. For an 
example using a custom form, see: 
https://docs.djangoproject.com/en/dev/ref/contrib/admin/#django.contrib.admin.ModelAdmin.form

But why don't you want a choicefield in the admin then?

session_key varies

[Wim Feijen]

Hi,

Is it normal that a session_key varies when a user is not logged in? And if 
so, should I then use request.COOKIES instead to store information in?

In one of my projects, users can order a calendar and upload their own 
photos, one for each month. In between, I like to keep track of which 
photos have been uploaded to a certain calendar. Users don't need to login 
to do this. 

First, I was using the session_key to keep track of a calendar order, but I 
noticed that the key kept on varyingr when a colleague on a Mac clicked a 
button.

Now I am wondering whether this is normal behavior, or can I do something 
to prevent it. 

And should I use request.COOKIES instead? 

Thanks for your help!

Wim

Re: how to import excel file into django models?

[Wim Feijen]

Hi,

Yesterday I did some research on this topic and I would like to recommend 
looking at examples on github, for example:
https://github.com/edcrewe/django-csvimport
or
https://github.com/foreveryh/django-excel-import

But I didn't use any of them, because I decided to re-use my own code.

image browsing from a textfield

[Wim Feijen]

Hello, 

For an e-learning app in development, we want editors to be able to edit 
html (TextField) within our app (not the admin), and insert formatted text, 
images and (Vimeo) video in there.

At the moment, I am looking into using TinyMCE (django-tinymce) combined 
with django-filebrowser. During my research, I came across many other 
solutions (Mezzanine, markup, django-adminfiles, oembed).

I am curious at what solutions you chose in order to edit html with images 
and why?

Best regards, Wim

How to use SESSION_COOKIE_DOMAIN on two subdomains

[Wim Feijen]

Hello,

I'd like to share the same session across two subdomains, namely:
crm.trumpetcms.nl
wtsadvocaten.trumpetcms.nl

Do I have to set the SESSION_COOKIE_DOMAIN in both settings.py files?
Or just in one?

Is this line correct?
SESSION_COOKIE_DOMAIN = '.trumpetcms.nl'

I am hosting the projects using an apache/nginx combination and
virtual hosts.

In Google Chrome, Incognito mode, what happens is, when I log into the
server at:
http://wtsadvocaten.trumpetcms.nl/admin/

I'm still begin asked to login at:
http://crm.trumpetcms.nl/

I am using Django 1.3.0.

Any help will be very much appreciated, thanks!

Am I overlooking something or is this a bug in ModelForm?

[Wim Feijen]

Hello,

I am using a form which (simplified) looks like this:

class AdvancedSearchForm(forms.ModelForm):
email = forms.CharField(label='Emailadres', required=False)

class Meta:
model = Address
fields = [
'last_name',
'middle_name',
'first_name',
'email',
'street',
]

Because it is a search form, I do not want to validate the e-
mailfield. However, whenever I add 'email' to get the order of the
meta fields right, default email validation is used.

I am very surprised at that. Why doesn't it honor my specified email
field which is a CharField? It should get precedence, right?

Am I overlooking something? Or is this a bug?

For further reading, see:
https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#overriding-the-default-field-types-or-widgets
and: 
https://docs.djangoproject.com/en/dev/topics/forms/modelforms/#changing-the-order-of-fields

templatetags and refresh

[Wim Feijen]

Hello,

At www.mkb-rotterdam.nl we use a template tag to display NewsItems in
different formats on the homepage.

However, when a new NewsItem is added, it does not appear at once.

Might this have to do with the fact that we use a template tag to get
the NewsItems out of the db?

Our query is:

newsitems = NewsItem.objects.filter(Q(expires_at__gt = datetime.now())
| Q(expires_at__isnull = True), effective_at__lte = datetime.now(),
is_active=True).order_by('-news_timestamp')

Or is datetime.now() fixed to the past?

What would be a proper way to solve this then? Maybe add a post-save
signal but how could we use this then to refresh the tag?

If something else is the matter, or just if you're interested: we host
our site using a virtual apache + mod_wsgi + nginx.

Thanks for your help!

Wim

Re: admin won't load revisited

[Wim Feijen]

Hi Octopus,

What do you mean by: "won't load correctedly"?

Is there an admin interface at /admin/ ? If not, did you enable the
admin in your settings.py and in your urls.py?

Is there one or more object missing from the admin interface? If there
is one missing, maybe you've made an error in your admin.py file,
which causes the object not to load in the admin. Comment your
ModelAdmin instances and try again, if necessary go back to the most
basic admin.site.register(MyModel)

Do the static files (css, js) not load? Then maybe your paths in
settings.py are not configured properly.

Hope this helps, and if you need any further assistance please let us
know what exactly is wrong.

Good luck!

Wim

Re: Reusing actions "Save and continue editing" and "Save"

[Wim Feijen]

Hi Lom,

I would recommend the following:
1. Add all three buttons to your template
2. In your view, handle the form saving and then determine which
button has been pressed.
3. Accordingly, redirect to the same url (for example, redirect("/
address/14") for viewing, redirect("/address/14/edit") for continue
editing, or redirect("address/add") to add another).

For the redirect function, see:
http://docs.djangoproject.com/en/dev/topics/http/shortcuts/

Hope this helps.

Best regards,

Wim

Re: Building Privacy Options Like Facebook with Django

[Wim Feijen]

Hi Corey,

I would recommend using a UserProfile for this, which is bound to a
user (so make sure an authenticated user can access only his profile
by using request.user.get_profile() in your views.

See: http://docs.djangoproject.com/en/dev/topics/auth/

Good luck!

Re: extends a template that is stored in an app template directory

[Wim Feijen]

Hi Owidjaya,

Common usage is to refer to your_app_name/template_name.html , so you
can put for example

{% extends "datagrid/template1.html" %}

in your client template.

So it is recommended to store your templates in a directory
your_app_name/templates/your_app_name/template_name.html

For more info, see http://docs.djangoproject.com/en/1.2/topics/templates/

Hope this helps.

Best regards, Wim

filter users by group

[Wim Feijen]

Hello,

I am banging my brain against the wall but it doesn't help and all I
get is brain damage. Maybe you can help me find a solution for the
following problem?

How can I add a filter to the django admin User interface (/admin/auth/
user/) so I can filter Users by Group?

What I have thought of, is:
1. Alter the template templates/admin/auth/user/change_list.html and
edit it to add a list of existing groups as links.
2. Redirect to ?group_id=1. THIS STEP FAILS!
3. Write a custom UserAdmin and overwrite the queryset method to show
only users of a group, thus:

class UserAdmin(admin.ModelAdmin):
model = User

def queryset(self, request):
group_id = request.GET.get('group_id', '')
if group_id:
return Group.objects.get(id=group_id).user_set.all()
else:
return super(UserAdmin, self).queryset(request)

try:
admin.site.unregister(User)
except admin.sites.Unregistered:
pass
admin.site.register(User, UserAdmin)


The missing link is step 2. How on earth do I get a request.GET
parameter through django's normal filtering process/ how can I combine
it. When I try '/admin/auth/user/?group_id=1', django redirects me to
'/admin/auth/user/?e=1'

Any help and tips will be very much appreciated, thank you!

If someone's has ever done this, I'd really like to know!

Wim

limit on date in postgres/django

[Wim Feijen]

Hello,

Do you know whether there is a minimum to a date? In my project, I'd
like to add birthdays from way back, from people born on 21 january
0061 for example.

When trying to write these dates to the db, I get the following error.
I'm using Django 1.0.5 alpha and Postgres 8.3.9.

Re: formsets and empty results

[Wim Feijen]

Hi Dexter, thanks for your answer,

The urls you gave are about forms, not formsets? My code looks like
this:



@teacher_required
def add_students(request):
school = School.objects.for_user(request.user)

class StudentForm(UserCreationForm):
name = forms.CharField(label='Naam')
group = forms.ChoiceField(label='Groep')
def __init__(self, *args, **kwargs):
super(StudentForm, self).__init__(*args, **kwargs)
self.fields['group'].choices = [(g.id, g.name) for g in
StudentGroup.objects.for_school(school)]

from django.forms.formsets import formset_factory
StudentFormSet = formset_factory(StudentForm, extra=10)
if request.method == 'POST':
formset = StudentFormSet(request.POST)
if formset.is_valid():
for form in formset:
if form.is_valid():
user = form.save()
student = Student(user=user,
name=form.cleaned_data['name'], group_id=form.cleaned_data['group'])
student.save()
return HttpResponseRedirect(reverse('schooladmin_students'))
else: #GET
formset = StudentFormSet()

base_template = get_base_template(request.user)
return render_to_response('school/add_students.html', {
'formset': formset,
'base_template': base_template
}, context_instance=RequestContext(request))

---
The StudentForm is defined over here because I could not set the
groups otherwise. I am using Django 1.0 . After the post, I'd like to
ignore empty forms in the formset.

Is this possible?

Best regards, groeten van Wim

formsets and empty results

[Wim Feijen]

Hi all,

Can some of you please help me with the following?

For an application, I need to display the same form ten times over.
Filling in each form is optional. Of course, I'd like to keep this
safe & simple and therefore I am looking at formsets.

Is it possible to use a formset, call formset.is_valid() and that it
ignores empty forms?

I'm using the forms only for adding new data, not for altering
existing data.

Thanks!

Best regards, Wim

DateFormat and localization

[Wim Feijen]

Hi,

I'm unsure if and how to use DateFormat from django/utils/
dateformat.py .

I'd like to use a local (Dutch) representation of dates. What I get
is:
u'26th March 2010'

I'd like that to be in Dutch. How do I do that?

Major thanks!

Wim


My IPython looks like this:

In [1]: import datetime

In [2]: d = datetime.datetime.now()

In [3]: from django.utils.dateformat import DateFormat

In [4]: df = DateFormat(d)

In [5]: df.format('jS F Y')
Out[5]: u'26th March 2010'

In [6]:

In [7]: import settings

In [8]: settings.USE_L10N
Out[8]: True

In [9]: settings.LANGUAGE_CODE
Out[9]: 'nl'

In [10]: settings.LANGUAGES
Out[10]: (('nl', 'Dutch'),)

admin rows aren't ordered as expected

[Wim Feijen]

Hello,

In my admin interface, the data isn't ordered as expected. What I get
is:
Provincie/Land   Type
Limburg Provincie
Groningen  Provincie
Utrecht  Provincie
etc.
which clearly isn't alphabetical order, while I do specify that
provinces should be ordered that way. In my python manage.py shell the
provinces are ordered alphabetically. What could be wrong?

admin.py:
class ProvinceAdmin(admin.ModelAdmin):
list_display = ('name', 'type')
actions = None

admin.site.register(Province, ProvinceAdmin)

models.py:
class Province(models.Model):
TYPES = (
('c', 'Land'),
('p', 'Provincie'),
)
name = models.CharField(max_length=200, verbose_name="Provincie/
Land")
type = models.CharField(max_length=1, choices=TYPES, default='c')

def __unicode__(self):
return self.name

class Meta:
ordering = ('-type', 'name',)
verbose_name = 'Provincie/Land'
verbose_name_plural = 'Provincies/Landen'

For the record, I am using django trunk revision 12295 .

save method manytomany

[Wim Feijen]

Hi,

Will you help me please?

I've got a model called Card which has a ManyToMany relationship to
Tag. When I save a Card, I'd like to create a Product as well, which I
want to have the same ManyToMany relationship to tag.

How do I access the instance's tags? self.tags.all() gives an empty
list, while if I check after saving, the card actually has tags. My
code is below. For the record, I am using Django 1.0.5.

Major thanks!

Wim

class Card(models.Model):
product = models.ForeignKey(Product, editable=False,
null=True)
name   = models.CharField('name', max_length=50, unique=True,
help_text='A short and unique name or title of the object.')
identifier = models.SlugField('identifier', unique=True,
help_text='A unique identifier constructed from the name of the
object. Only change this if you know what it does.', db_index=True)
tags   = models.ManyToManyField(Tag, verbose_name='tags',
db_index=True)
price  = models.DecimalField('price', max_digits=15,
decimal_places=2, db_index=True)

def add_product(self):
product = Product(
name = self.name,
identifier = self.identifier,
price = self.price
)
product.save()
return product

def save(self, *args, **kwargs):
# Step 1: Create product
if not self.id:
self.product = self.add_product()
# Step 2: Create Card
super(Card, self).save(*args, **kwargs)
# Step 3: Copy cards many to many to product
# How do I do this?
print self.tags.all() # gives an empty list??


Any help is appreciated

Re: Modeling and validating international addresses?

[Wim Feijen]

Hi ringmeup again,

What I would do is choose the most common one and use that. In many
web applications I find that people use American-style addresses,
where I have to enter my state which has no equivalent in the
Netherlands, but nevertheless I have to.

Another good solution would be to define a common BaseAddress on which
you expend for each country's customs, and if you want to make your
application really slick, you can throw in some Javascript to
dynamically alter the form displayed. Though I would certainly opt for
simplicity and let the user first select a country, and then render
the appropriate form in the next script.

What does google find?

Wim

Re: Overriding verbose_name in contrib or 3rd-party apps?

[Wim Feijen]

Can you please post some more information for what purpose you like to
do this?

My first guess would be you are using the admin interface. Dirty
workarounds are: copying code and adapting it, importing from your
adaptation in stead of the original. Maybe modifying the admin view to
do something differently. Or adapt a translation?

Probably there are a hundred better ways, but you can try these for a
start.

It does nothing to help you solve your problem, but mod_wsgi is

Re: rendering a table

[Wim Feijen]

Hi Hugo,

Your template code, does it actually contains  and  ?
Like below?


{% for row in rows %}

{% for value in row %}
{{ value }}
{% endfor %}

{% endfor %}


Then, what does rows look like? Can you post your output please? To
get this output, for example, use "print rows" before you render the
template, and post the result here. That would help!

Wim

Re: OperationalError: unable to open database file, when saving existing object

[Wim Feijen]

So, if I understand correctly, creating new objects and saving them to
the database works correctly, and updating objects fails. Is that
correct? Is it an update from the admin interface or from code written
by you?

If the former, it might have something to do with db privileges. Which
back-end are you using, sqlite? In that case, are you running the
project while being the same user as the owner of the sqlite db-file?
If the back-end is another database, did you edit and modify write
privileges?

Wim

question about UserChangeForm

[Wim Feijen]

Hello,

In my views, I'd like to be able to rename a user using the
UserChangeForm from django.contrib.auth.forms . However, the form does
not validate. Should I use another instance than request.user?

Errorlist:

Translation: "Dit veld is verplicht." is Dutch for "This field is
required."

passwordDit veld
is verplicht.last_loginDit veld is verplicht.date_joinedDit veld is verplicht.

In views:

def rename(request):
'''Displays a form which can rename a user'''
if request.POST:
form = UserChangeForm(request.POST, instance=request.user)
if form.is_valid():
result = form.save()
return HttpResponseRedirect("/preferences")
print form.errors
else:
form = UserChangeForm(instance=request.user)
context = {
'form': form,
}
return render_to_response('rename_user.html', context)

Thanks! Wim

python manage.py syncdb failed for me, saying: there is no such table

form fun

[Wim Feijen]

Hello,

Several clients asked me whether they could have a form on their
website, which displays like this:

Description of field 1
Title: (input field)
help_text

Description of field 2
Title2: (input field2)
help_text2

etc.

I was wondering whether this is a common case and I like to poll you:

Did you ever encounter a situation like this?

The reason I am asking is, if it indeed turns out to be a common case,
and if it is, it might make sense to make a feature request which
allows us to have a "description_text" in the forms.Field definition
as well.

In one use case, my clients are making forms which they generate
themselves using a generator in the admin (if you're interested in the
code, I will send it to you) and the logic will get very complex if I
need to add my own desciption_field. On the other hand, I can always
try to overwrite the Field function :) , I'll look into that.

Re: Forms: custom clean for DateField

[Wim Feijen]

Hi Marco,

In Django 1.0, you don't need to call clean from clean, Django will do
that automatically for you. :)

So what you can do is:

def clean(self):
data =  self.cleaned_data

if (data['firstDate'] >= data['lastDate']):
raise ValidationError("Error")

# else
return data

That should work.

For more info, see: http://docs.djangoproject.com/en/dev/ref/forms/validation/

thread by latest post

[Wim Feijen]

Hello,

While writing a forum app, I ran into a problem: I am unable to sort a
list of threads by date of their latest post.

My models look like:

class Thread(models.Model):
club = models.ForeignKey(Club)
name= models.CharField(_('Thread'), max_length=100)
date = models.DateTimeField(auto_now = True )

def __unicode__(self):
return self.name

class Post(models.Model):
thread = models.ForeignKey(Thread)
date = models.DateTimeField(auto_now=True)
subject = models.CharField(_('Subject'), max_length=100)
text = models.TextField(_('Text'))

def __unicode__(self):
return self.subject

I know that I can get the date of the latest post of a thread by
using:
Thread.objects.get(id=3).post_set.all().latest('date').date

However, I do not know if there is any possibility of me using that
date to sort a QuerySet of threads, which I get by using
Thread.objects.filter(club=1). Is there any way to do this in Django?

Many thanks for your help!

pretty urls lost in dns

[Wim Feijen]

Hello,

I'm happily running a project on a Strato web server.

I've forwarded the domain name 'uwadresboek.nl' to my server, it's at
IP 85.214.104.194 . Everything works fine, except that:

1. Pretty URLs are lost.

I can type www.uwadresboek.nl/prices and everything is well. In
addition, I can click on a link, f.e. 'read more' and I get
redirected. But now the URL in my browser does not show a change,
which I find very confusing. What could be the cause of the browser
not showing the URL and what can I do about it?

Using www.go2people.net (without DNS forwarding), everything is OK.

2. The background flashes while switching screens.

Any help would be much appreciated!

Re: Django 1.0 lighttpd FastCGI redirect issue

[Wim Feijen]

Hi Anders,

For me, removing the slash in the FORCE_SCRIPT_NAME seemed to work. I
am not using the admin interface, so I can't check on that.

So I added to settings.py:

FORCE_SCRIPT_NAME=""

I totally agree that this change with great consequences for all
lighttpd users is poorly documented.

Best regards,

Wim

Re: Can I loop over attributes in model.attribute?

[Wim Feijen]

Thanks Russell!

I suppose the code I want to get looks like:

settings = Settings.objects.get(owner=userid)
for switchable in ['groupon', 'companyon', 'addressfirst',
'extendnames', 'clubfieldson']:
if switchable in data:
settings._meta.get_field(switchable). = True
else:
   settings._meta.get_field(switchable). = False

My remaining question is, as you may have understood, what text do I
use instead of  ?

I imagine I could have been using a python function to list some
options, but I was unable to find out how. I apologize for being
stupid.

Yours sincerely,

Wim

PS Another thing is, _meta is apparently a hidden function I am not
supposed to be using. Do you recommend filing this conversation as a
bug/feature request? Because I would be delighted when we could
address object columns as settings['groupson'] = False, in order to
open up all kinds of possible interactions.

sessions, Internet Explorer cookies and domain forwarding

[Wim Feijen]

Hello everyone,

Django is great. But I am experiencing a problem when trying to log in
to my site using Internet Explorer.

When I go to:
http://85.214.104.194:8098/accounts/login/
logging in works as it should.

However, at:
http://www.jouwadresboek.nl/
, which is hosted at Strato and forwarded to the above, logging in
fails, because I.E. cannot set the cookie.

How do I solve this?

Any tips and hints you can give me, would be appreciated very much,

Thanks for your help,

Wim

Re: use my own widgets when creating a form out of a model

[Wim Feijen]

Hi Richard and Rishabh,

Thanks for your help.

Actually, I want all fields to show up as a textarea with 40
columns. :}  So I guess I just have to define each field separately
without using inheritance. Which is a pity. It's a solution, though.

Bye,

Wim

use my own widgets when creating a form out of a model

[Wim Feijen]

Hello people,

Being able to work with Django is very helpful to me. However, I am
unsure whether I can create a form out of a database model and then
customize that form. Using widgets to increase the textarea to 40
would be great! But after reading  the documentation I am convinced I
cannot do that.

One solution I can think of, is to loop over the fields in the form
and start changing those? Is that possible? Then again, is that the
proper way to do it?

My models are below.

Thanks for any help!

Wim



class Person(models.Model):
name = models.CharField(max_length=100)
notes = models.CharField(max_length=100, blank=True)
email = models.EmailField(max_length=100, blank=True)
cellphone = models.CharField(max_length=100, blank=True)
officephone = models.CharField(max_length=100, blank=True)
chat = models.CharField(max_length=100, blank=True)
skypename = models.CharField(max_length=100, blank=True)
street = models.CharField(max_length=100, blank=True)
number = models.CharField(max_length=100, blank=True)
suffix = models.CharField(max_length=100, blank=True)
zip = models.CharField(max_length=100, blank=True)
city = models.CharField(max_length=100, blank=True)
country = models.CharField(max_length=100, blank=True)
photo = models.ImageField(upload_to='.', blank=True)
company = models.ManyToManyField(Company)
groups = models.ManyToManyField(Group)
deleted = models.BooleanField(default=False)
shared = models.ManyToManyField(User, related_name='shared')
owner = models.ForeignKey(User)

def __str__(self):
return self.name

class PersonForm(ModelForm):
class Meta:
model = Person
fields = ['name', 'notes', 'email', 'cellphone',
'officephone', 'skypename', 'street', 'number', 'suffix', 'zip',
'city', 'country', 'photo']
