referencing a specific item in a list...
After extensive searching, I'm still unable to find a way to reference
individual items in a list without using a for loop.
For example, I have this basic code in my views.py:
project_list = Project.objects.all().order_by('-id')[:6]
t = loader.get_template('portfolio/index.php')
c = Context({
'project_list' : project_list,
})
Now, in my template file I want to be able reference the six
different elements in the list directly, without having to loop
through them. How can I do this?
I've tried project_list[1] but that just errors out.
Thanks,
Walt

Re: referencing a specific item in a list...
Thank you! Works perfectly! Major complaint about Django: some simple things like syntax and complete API details are either missing from the documentation or glossed over, a la the link you included. I would've taken from that to try my original "project_list[1]" since I thought it would be a list, not a method or attribute lookup... Thanks again!

Admin calendar popups on datefield suddenly missing
Hi all, I don't know of any changes I've made recently other than checking out the latest django code but the date picker / popup on all admin datefields has suddenly disappeared. Any clues as to how to get this back or what might have caused it to disappear in the first place?

If so it might be this bug:http://code.djangoproject.com/ticket/11967 No, I don't think this is the problem. First, I'm not using TinyMCE on the app at all, secondly, the problem happens across all browsers, and third the code to display the date picker isn't even present in the source HTML for the admin pages, so I think something happened server-side to turn that feature off.

Re: Admin calendar popups on datefield suddenly missing
Okay, we're getting somewhere. It can find the JS file(s) just fine
and I see that the calendars are added dynamically. However, I'm
have found that it is generating a javascript error when the page
loads:
Error: gettext is not defined
Source File: http://tachamber.org/media/admin/js/calendar.js
Line: 26 [monthsOfYear: gettext('January February March April May June
July August September October November December').split(' '),]
Error: gettext is not defined
Source File: http://tachamber.org/media/admin/js/admin/DateTimeShortcuts.js
Line: 134 [today_link.appendChild(document.createTextNode(gettext
('Today')));]
Any ideas?

Defining the queryset admin pages use for ForeignKey or ManyToMany fields
It seems like this should be possible, and this is the closest, simplest solution I can find in the documentation: class InvoiceAdmin(admin.ModelAdmin): def formfield_for_foreignkey(self, db_field, request, **kwargs): if db_field.name == "books": kwargs["queryset"] = Book.objects.filter(sold=False) return db_field.formfield(**kwargs) return super(InvoiceAdmin, self).formfield_for_foreignkey (db_field, request, **kwargs) But this does not work at all. I need to do this in many places for a number of different forms, so it would be nice to be able to specify the queryset for ForeignKey fields in a form without completely recreating the admin form pages.

Re: limit_choices_to a value on a field in the same model
Here is an idea of what your forms.py should contain:
class AgencyForm(ModelForm):
class Meta:
model = Agency
def __init__(self, *args, **kwargs):
super(AgencyForm, self).__init__(*args, **kwargs)
if self.instance.id:
if self.instance.state_id:
counties =
County.objects.filter(state=self.instance.state_id)
county_field = self.fields['counties'].widget
county_choices = []
county_choices.append(('', '--'))
for county in counties:
county_choices.append((county.id, county.name))
county_field.choices = county_choices
Then in admin.py, make sure you have:
class AgencyAdmin(admin.ModelAdmin):
form = AgencyForm
Hope this helps,
Walt

Re: Is it possible to change the width of the boxes displayed by the filter_horizontal in Django admin interface?
You'll need add a stylesheet Media class to your admin class:
class ResizeFilterAdmin(admin.ModelAdmin):
#
class Media:
css = { 'all': ('/relative/path/to/supplemental.css'), }
Then, in that CSS file you'll need to specify the width of your
element:
/* by class */
.filtered {
width: 350px;
}
/* or by object id */
#id_yourfieldname_from {
width: 350px;
}
#id_yourfieldname_to {
width: 350px;
}
This should work. :-)

Re: Is it possible to change the width of the boxes displayed by the filter_horizontal in Django admin interface?
I'm sorry I wasn't more clear, the class Media just gets
added to your existing admin class. The path to the css
should be the path that is appended to your SETTINGS.PY
media path to reach the css file. The class ResizeFilterAdmin
was just an example name.
In other words, if your media path is: /var/www/media
and your css file is stored in /var/www/media/css/bisite.css
then your Media entry would be:
css = { 'all': ('/media/css/bisite.css',)}
So the full entry would be:
class ProfileAdmin(admin.ModelAdmin):
search_fields = ('profile_name',)
ordering = ('profile_name',)
filter_horizontal = ('profile_test',)
class Media:
css = {
'all':('/media/css/bisite.css',)
}
Does that make more sense? Again, I apologize for the
miscommunication!
Thanks,
Walt

Re: 'Context' object has no attribute 'render_context'
I'm not sure I know why your code is misbehaving, but any particular reason you aren't using render_to_response instead of template/context rendering? http://docs.djangoproject.com/en/dev/topics/http/shortcuts/#render-to-response It's much simpler!

Re: New python, django user... having issues
Windows 64 does make things interesting, but just to summarize what I do to install on Windows: Install python2.5: http://www.python.org/download/releases/2.5.4/ Install latest apache: http://httpd.apache.org/download.cgi#apache22 Install mod_python for python 2.5: http://archive.apache.org/dist/httpd/modpython/win/3.3.1/mod_python-3.3.1.win32-py2.5-Apache2.2.exe Install your database of choice (postgresql 9.0.1/ mysql): http://www.enterprisedb.com/products-services-training/pgdownload#windows http://www.mysql.com/downloads/mysql/ Install the appropriate python connector: http://www.stickpeople.com/projects/python/win-psycopg/psycopg2-2.4.win32-py2.5-pg9.0.3-release.exe http://sourceforge.net/projects/mysql-python/files/mysql-python/1.2.2/MySQL-python-1.2.2.win32-py2.5.exe/download I also usually install svn: http://www.sliksvn.com/en/download svn co http://code.djangoproject.com/svn/django/trunk/ Add python's bin to your path, add django-admin.py to your path and you should be good to go. The reason for using 2.5 is that mod_python or windows and the MySQL Python connector only support that version, at least as far as I have been able to find.

Re: django form converter to PDF
You can also check out the Python wrapper for pdftk. https://github.com/revolunet/pypdftk It allows you to take a pdf form and fill it dynamically and "flatten" it. Aside from that, Weasyprint also works pretty well. Walt On Monday, October 3, 2016 at 8:05:43 AM UTC-4, M Hashmi wrote: > > Hi, > > I need some simple library to convert a simple quote form to PDF.
