Re: How to prevent model formset from saving the empty forms?
Ok, I figured out why, but I still don't know how to fix it. I set a dropdown to empty_label = None, which automatically selects the first element. I want that, but the form then thinks it has changed because the value in the list of initial values is empty for that field, and I can't see how to set the initial value for the forms in a model formset.

Newbie: Help with validation
Hi all,
I have a model snippet that I wanna use to store phonenumbers:
e_mail = models.EmailField()
phone = models.CharField(max_length=15)
Mobile numbers in my country are 11digit numbers e.g 080,
Fixed Lines: (2 digit),7 digit e.g (01)755
I wanna try and validate this field on a form, ensuring that info supplied is
commensurate with above mentioned parameters:
def clean_phone(self):
if self.cleaned_data['phone'] :
raise forms.ValidationError('Phone Number wrong.')
return self.cleaned_data['phone']
Can anyone suggest a validation or regex pattern I can use? If there are other
field types I wouldn't mind too; PhoneNumberField(django.contrib.localflavor)
doesnt quite cut it for me.

Then you need a custom template filter. Something like this should do
the trick:
# in your templatetags module:
@register.filter
def get_attribute(obj, name):
return getattr(obj, name, u"")
# in your template
{% load youtemplatetags %}
{% for attrname in attributes %}
{{ obj|get_attribute:attrname }}

How to order "links" in the Admin?
Hi,
I'm testing Django for my first project using it.
I have a model like this:
from django.db import models
import datetime
class Directory(models.Model):
website_name = models.CharField(max_length=200)
website_url = models.CharField(max_length=200)
website_position = models.IntegerField()
pub_date = models.DateTimeField('date published')
Basicaly this model is for storing URL's, but I need to order them,
and for that I use "website_position" to control if the link will be
at the top or at the end or in the middles...
My question is, there is a better way to control the positions of the
links? Django Admin have any feature that could help to deal with this
specific case?
Please let me know.

RE: How to concatenate two variables in a template for evaluation..
Okay then which way do u recommend that i should follow in case
i need to displays objects with different no of properties
Example obj has propA and PropB
{{obj.propA}}
{{obj.propB}}
would work but i want it to be dynamic since the no and name of properties may
vary..
I tried writing all the properties of an object in a list and passing that list
obj to template
but it seems this is not just possible.. since
{% for prop in properties %}
{{obj}}+{{.prop}}
{% endfor %}
or other things similar to above do not work
Any suggestions..

Well you don't really give a lot of info, so my guess might be completely wrong. Do you use the django development server ( manage.py runserver) or do you run with apache / some existing server? Did you run the command "manage.py collectstatic"? -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: How to concatenate two variables in a template for evaluation..
You have to write it as {{ obj.title }} in your template. Django
templates are designed to allow very little in the way of logic; that
should take place in your views.

How to concatenate two variables in a template for evaluation..
hi I have been playing around with a certain scenario
Consider the following
{% for title in field %}
{{obj}}{{.title}}
{% endfor %}
Here obj is an object
and title are the various fields of that object.
How can i evaluate the entire thing in a template
Example
I want it to end up like this
{{obj.title}}
How can i do that from my previous code..
Any suggestions would be appreciated...

Re: Need help writing join Django query for this simple model..
This is where using the related_name kwarg comes in. You can also use the default value, which in this case is academics_set. I see you made most of the recommended changes to your model definitions. I'd just like to reiterate two: Remove the underscore in your model name. Remove the 's' from Academics (it shouldn't be plural). -- You received this message because you are subscribed to the Google Groups "Django users" group.

RE: Need help writing join Django query for this simple model..
okay so i got it working (Thanks to you guys) but i do have a question..
First my dbmodel is
class Student_Info(models.Model):
roll_no = models.IntegerField(primary_key=True)
cell_no = models.IntegerField()
e_mail = models.EmailField(max_length=30)
class Academics(models.Model):
roll = models.ForeignKey('Student_Info',to_field='roll_no')
gpa = models.IntegerField()
subject_code= models.IntegerField(primary_key=True)
supervisor=models.CharField(max_length=30)
So From Academics -> Student_info it works
>>> list=Academics.objects.all()
>>> obj=list[0]
>>> obj
>>> obj.roll.e_mail
u'syvlisa...@hotmail.com'
but from Student_info->Academics it doesnt work??
>>> list=Student_Info.objects.all()
>>> obj=list[0]
>>> obj
>>> obj.roll_no.gpa
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'int' object has no attribute 'gpa'
My question is how can i make it work both ways ?? Is that even possible???

You would really be better off naming Roll_No in Academics something like
"student_info". (And in general changing your naming conventions to match
Python, but this one field in particular is going to be very confusing if you
name it as you have). In the Django ORM, the field will be an object that
contains the associated Student_Info instance, it will not be a simple Integer
containing the Roll_No of that student. The fact that you have specified
Roll_No as the field to link on (which is unnecessary by the way, the primary
key field will be used by default) is irrelevant.
Then i tried this :
>>> from DbDemo.models import Student_Info
>>> list=Student_Info.objects.all()
>>> obj=list[0]
>>> obj
>>> obj.GPA
>>> obj.GPA
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'Student_Info' object has no attribute 'GPA'
GPA isn't an attribute of a Student_Info, it's an Attribute of Academics.
Student_Info has an associated academics object due to the OneToOne field in
Academics, to access it's fields you need to specify that is where the field is:
obj.academics.GPA
The naming of the field used to access the "backwards" relationship is noted
here:
https://docs.djangoproject.com/en/dev/topics/db/queries/#one-to-one-relationships
Then i tried
>>> from DbDemo.models import Academics
>>> list= Academics.objects.all()
>>> obj=list[0]
>>> obj
>>> obj.E_mail
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'Academics' object has no attribute 'E_mail'
E_mail is in the linked Student_Info object:
obj.Roll_No.E_mail
(this is why I mentioned Roll_No is probably not really what you want to name
that field)
>>> obj.Student_Info.GPA
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'Academics' object has no attribute 'Student_Info'
GPA is directly in the Academics object:
obj.GPA
Linking two models via a ForeignKey or OneToOne field doesn't make all the
attributes of one directly accessible in the other: you need to specify the
relationship you want to follow in order to get at whatever attribute you are
looking for.

'str' object has no attribute 'resolve' when access admin site
I keep getting this error:
'str' object has no attribute 'resolve'
when trying to accessing the django admin site and I can't figure out
why.
I have apps within my project that have their own admin.py files.
Could this cause it?
here is my urls.py:
from django.conf.urls.defaults import *
import settings
from django.contrib.auth.views import login, logout
from views import index, simple, complex
from django.views.generic.simple import direct_to_template
# Uncomment the next two lines to enable the admin:
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Example:
# (r'^django_jchat/', include('django_jchat.foo.urls')),
# Uncomment the admin/doc line below and add
'django.contrib.admindocs'
# to INSTALLED_APPS to enable admin documentation:
(r'^admin/doc/', include('django.contrib.admindocs.urls')),
# Uncomment the next line to enable the admin:
(r'^admin/', include(admin.site.urls)),
...
and my admin site has been installed correctly in my settings.py file.
Help please. thank you.

Re: Passing tuple values to a model choices field
The label_from_instance should simply return the obj. I don't think any
fuzzy codes is needed as
described in the Django docs [1]
The method label_from_instance already converts the objects to string. So a
simple override like this:
class MyModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj
I made changes like this to my code:
""" Introduced a new model to store the form field select values """
class Branch(models.Model):
"""Branch"""
name = models.CharField(max_length=50)
name_branch = models.CharField(max_length=50)
address_1 = models.CharField(max_length=100)
class Meta:
db_table = 'branch'
def __unicode__(self):
return u"%s | %s | %s" % (
unicode(self.name_branch),
unicode(self.address_1))
""" subclass of ModelChoiceField
class BranchModelChoiceField(ModelChoiceField):
def label_from_instance(self, obj):
return obj # Just return the obj
class TransactionUpdateForm(forms.ModelForm):
branchqs =Branch.objects.values_list('name_branch', flat=True)
branches_field = BranchModelChoiceField(branchqs) #ModelChoiceField
instance
class Meta:
model = Transaction
fields = ('branch_name')
In template file I do this:
{{form.branches_field}}

RE: Need help writing join Django query for this simple model..
Thanks for the suggestions..
okay suppose i change my models to something like this
class Student_Info(models.Model):
Roll_No = models.IntegerField(primary_key=True)
Cell_No = models.IntegerField()
E_mail = models.EmailField(max_length=30)
class Academics(models.Model):
#Roll_No = models.ForeignKey('Student_Info',to_field='Roll_No')
roll = models.OneToOneField('Student_Info',to_field='Roll_No')
GPA = models.IntegerField()
Now how can i access the academic fields through the student object
>>> from DbDemo.models import Student_Info
>>> list=Student_Info.objects.all()
>>> obj=list[0]
>>> obj
Now i got the Student_info object. and i know Student_Info is linked to
Academics via Roll_No..
so now how could i read the GPA in Academics any suggestions??

Linking two models via a ForeignKey or OneToOne field doesn't make all the

Re: Admin model listing custom ordering
Thanks, Christian.
After trying your attempts, I solved the problem by creating an
additional "order" field in the ForeignKey. So in the referenced model
I had to do:
class Meta:
ordering = ['fkfield__order']
That's not so elegant as I wished it to be, but it's not that ugly too, IMO.

RE: Using Form Elements Widgets direclty in HTML
Could you please give an example.. say of a simple input box in html its done like How would i replace the default input box with the one from Django widgets??

You would really be better off naming Roll_No in Academics something like
"student_info". (And in general changing your naming conventions to match
Python, but this one field in particular is going to be very confusing if
you name it as you have). In the Django ORM, the field will be an object
that contains the associated Student_Info instance, it will not be a simple
Integer containing the Roll_No of that student. The fact that you have
specified Roll_No as the field to link on (which is unnecessary by the way,
the primary key field will be used by default) is irrelevant.

GPA isn't an attribute of a Student_Info, it's an Attribute of Academics.
Student_Info has an associated academics object due to the OneToOne field in
Academics, to access it's fields you need to specify that is where the field
is:
obj.academics.GPA
The naming of the field used to access the "backwards" relationship is noted
here:
https://docs.djangoproject.com/en/dev/topics/db/queries/#one-to-one-relationships

E_mail is in the linked Student_Info object:
obj.Roll_No.E_mail
(this is why I mentioned Roll_No is probably not really what you want to
name that field)
> >>> obj.Student_Info.GPA
>
> Traceback (most recent call last):

GPA is directly in the Academics object:
obj.GPA
Linking two models via a ForeignKey or OneToOne field doesn't make all the
attributes of one directly accessible in the other: you need to specify the
relationship you want to follow in order to get at whatever attribute you
are looking for.

Trying to simplify the last post
Hello there
I'm trying to make this as easy as possible, but it's pretty
complicated.
Here's my form
class EventBookForm(ModelForm):
"""A form for governors to email to govwales with details of which
events they wish to attend"""
title = CharField()
firstname = CharField()
surname = CharField()
address = CharField(widget=Textarea(attrs={'rows': 5, 'cols': 80}))
postcode = CharField()
telephone = CharField()
email = EmailField()
govtype = Field(widget=Select(choices=GOVTYPELIST))
schoolname = CharField(widget=Textarea(attrs={'rows': 2, 'cols':
60}))
authority = CharField()
workshops = MultipleChoiceField()
requirements = CharField(widget=Textarea(attrs={'rows': 5, 'cols':
80}))
class Meta:
model = Event
def __init__(self, *args, **kwargs):
super(EventBookForm, self).__init__(*args, **kwargs)
workshop_choices = []
data = Workshop.objects.filter(evt_workshop='80')
print data
for d in data:
workshop_choices.append((d.title,d.title))
self.fields['workshops']=MultipleChoiceField(widget=CheckboxSelectMultiple,
choices=workshop_choices, required=False)
As you can see I've hard coded the id of the event into this section
data = Workshop.objects.filter(evt_workshop='80')
If I could pass the request object into the form, or the event ID
itself,I could get at the right data for the workshop_choices list.
Here's the view

But anyway: the only correct way to import your project's settings module is to use the first form.

I've got a form that I then use to create the email, with the view
forms.py
class EventBookForm(ModelForm):
workshops = MultipleChoiceField()
views.py
def event_book(request,edate, slug):
I run through some logic here based on request type, and put together
the email that sends off the selected items
I also throw data back to the form, like this
eventdetail = Event.objects.filter(slug=ventslug,start_date=ventdate)
for d in eventdetail:
workshopid = d.id
workshop = Workshop.objects.filter(evt_workshop=workshopid)
cats = formextra.objects.all()
context = Context({'form': form, 'cats': cats, 'eventdetail':
eventdetail, 'workshop': workshop })
return render_to_response('forms/eventbookform.html', context,
context_instance=RequestContext(request))
My problem is this
I can't find a way to list the workshops that are associated with the
event AND send which ones are selected in the tick boxes in the email.
I can list the workshops that are associated with the event in the
view
workshops = Workshop.objects.filter(evt_workshop=d.id)
workshoptitlearray = ''
for w in workshops:
workshoptitle = w.title
workshoptitlearray = workshoptitlearray + ', '
+ w.title
I think I need to do something like this in the form though, in order
to send the items that have been selected
class EventBookForm(ModelForm):
workshops = MultipleChoiceField()
requirements = CharField(widget=Textarea(attrs={'rows': 5, 'cols':
80}))
class Meta:
model = Event
def __init__(self, *args, **kwargs):
self.request = kwargs.pop('request', None)
super(EventBookForm, self).__init__(*args, **kwargs)
workshop_choices = []
data = Workshop.objects.all()
print data
for d in data:
workshop_choices.append((d.title,d.title))
self.fields['workshops']=MultipleChoiceField(widget=CheckboxSelectMultiple,
choices=workshop_choices, required=False)
As you can see, I'm getting myself into a bit of a mess here, if
anyone can shed any light on how I access the information passed from
the view
context = Context({'form': form, 'cats': cats, 'eventdetail':
eventdetail, 'workshop': workshop })
return render_to_response('forms/eventbookform.html', context,
context_instance=RequestContext(request))
Any help, greatly appreciated, as always

Re: how to get request object out of views
hi, Ok, It is a good method to get the current user. I am sorry for that. But i just do maintain a django project, and i do not want to change the template structure. And now, I have found a new method to resolve the problem. through a variable CURRENT_USER defined in settings.py to save the current user in a view. and get the current_user from settings.CURRENT_USER. thanks for your reply. And i found a strange appearance. PART_ONE: I defined a variable named CURRENT_USER and import the settings in a view like below: from gmadmin import settings ## the gmadmin is the name of the topo directory then assign request.user to settings.CURRENT_USER PART_TWO: Get the settings.CURRENT_USER in a .py file the code: import settings user = settings.CURRENT_USER But it reported a problem: the settings.CURRENT_USER is None . and the problem disappeared when i use "import settings" instead of "from gmadmin import settings" on PART_ONE。 Could you talk about it? regards, kejun On Tue, Aug 9, 2011 at 4:23 PM, Daniel Roseman wrote: > > On Tuesday, 9 August 2011 02:33:47 UTC+1, oops wrote: >> >> Hi, >> >> May be you miss understanted my meaning. >> >> I just want to get the current user object in a normal .py file out of >> views. >> >> And this file just offer some data according to different user. >> >> Do you have any methods to get the goal? >> >> thank you >> >> regards, >> kejun >> > > No, Tom understood you fine, and his answer was quite clear.

Because you need to use a RequestContext to render the template.

Re: How can I use {{variable}} in custom templatetag?
{% get_related_entries weblog.entry 5 from object.categories as
related_entries %}
{% for entry in related_entries %}
{{ entry.title }}
{% endfor %}
class RelatedEntryNode(template.Node):
def __init__(self, model, number, categories, varname):
self.model = model
self.number = int(number)
self.categories = template.Variable(categories)
self.varname = varname
>Ok, so this means that:
>self.model is a string; literally, in your example, "weblog.entry"
No, self.model shouldn't be a string. It should be the model for Entry in
app weblog (and I use it like that in other custom template tags that work)
The templatetag is used when on a blog entry detail page and should give
a list of related entries (with corresponding categories) . It comes from
django.db.models.get_model() (p117 of Practical Django Projects)
>But that's fine, because your render() method is going to compute some
>value, probably a list of Entry instances in this case, and then it will
>create a new context variable, with the statement;
>context[self.related_entries] =
This is where the problem is. I don't get a computed list. It returns
nothing instead of 1 other related blogentry (in this case)
I'm really stuck now in solving this quite common query:
* a blog entry is shown in a detail page
* this blog entry has categories (m2m relation) Let's assume categories C1
and C2
* other blog entries have the same categories (also C1 and C2, I'll skip the
OR relation for now)
* through a custom template tag I want to get the list of Entry instances
that have categories C1 AND/OR C2 and display them on the detailpage.
* Three database tables are involved in this query
** weblog_entry (which contains the entries)
** category_entry (which contains the categories)
** weblog_entry_categories (which joins the entry with the category)
When displaying the blog entry, Django also references these 3 tables
(otherwise I wouldn't get the category name in the template.)
I'm going around in circles and am afraid I don't see where the problem
could be. I reread the books, went through the documentation and searched
the internet, but am getting nowhere. I'm sure I'm overcomplicating things
as this should be a quite easy common query to perform.
Maybe you could give a hint or a pointer how you would achieve this thorugh
a template tag?

Static file problem using the development server
I tried using a style sheet served as a static file with the tutorial
project. In settings.py, I defined STATIC_URL = /static/ and
STATICFILES_DIRS = ('/path/to/project/static/',). Then I defined a
base_html template with a line in the HEAD of the form
and put style.css in directory /static/. Finally, I defined
index.html, detail.html, etc., as given in the tutorial to each extend
base.html.
Everything works perfectly, except that only one template
(detail.html) correctly processes the {{ STATIC_URL }} value to find /
static/style.css. In every other template, {{ STATIC_URL }} evaluates
to the empty string, giving just style.css, which does not exist of
course.
Every template extends the single base template in the same way. So
why does {{ STATIC_URL }} work for some templates and not others?
