ValueError when uploading image
Hi,
I'm new to Django and programming in general. I've been trying to
create a form that simply uploads images and saves them to a app
folder. I'm using MySql with Django svn. Here's my model:
class Images(models.Model):
prim = models.AutoField(primary_key=True, db_column='PRIM') #
Field name made lowercase.
photos = models.ImageField(db_column='PHOTOS', upload_to='img',
blank=True) # Field name made lowercase.
items = models.CharField(max_length=255, db_column='ITEMS',
blank=True) # Field name made lowercase.
date = models.DateField(null=True, db_column='DATE', blank=True) #
Field name made lowercase.
class Meta:
db_table = u'IMAGES'
Here's my view:
class PictureForm(ModelForm):
class Meta:
model=Images
exclude = ('prim',)
def image_loads(request):
form=PictureForm()
if request.method=='POST':
form=PictureForm(request.POST, request.FILES)
if form.is_multipart():
form.save()
form=PictureForm()
return render_to_response('photos.html', {'form':form, },
context_instance = RequestContext(request))
return render_to_response('photos.html', {'form':form, },
context_instance = RequestContext(request))
Here's photo.html:
{%extends "base.html" %}
{%block head%}
{%endblock%}
{%block content%}
{{ form.as_p }}
{% if comment %}
{{comment}}
{%endif%}
{%endblock%}
Here's the error message:

Apache2 permission denied problem
Hi, I'm new to Django, and am trying to write a csv file and attach it to an email that is sent upon completion of a sales order. All works fine in the developement server, but when I switch to Apache2 I get an error message that either says' No such file or directory, ../orders1/ csv_files/ or Permissions denied etc. All works fine when I use the developement server.

problem rendering html images in browser
I've had trouble rendering images in my browser. I just get a broken link. Any thoughts on how to fix this?

jquery ajax form problem--Can't render template variables
I'm new to programming and can't figure out how to properly render the
{{comment}} and {{username}} variables in the element
below using jquery and the ajax form plugin. Everything posts to the
database just as it should. However, I want to show what gets posted
in the template after submission. What happens is the entire html page
gets inserted in the element. The images, everything,
gets duplicated as the response_text is inserted. Note that the
following code has a lot of simple test scripts I'm attempting to use.
My template looks like this:
(I'm referencing a javascript file, global.js in the template, which
is included below it):
{% extends "base.html" %}
{%block content %}
Welcome to Site
{% include "form.html" %}
This will fade out
Here is the camo image
Users and comments:
{{comment}}
{{username}}
{% if error %}
Errors:
{{error}}
{% endif %}
{% endblock%}
Here is global.js
$(document).ready(function(){
$("div.htm").text("The DOM is now loaded and can be
manipulated.");
$(":header").css({ background:'#CCC', color:'green' });
$("img").css({ width:'25%' });
$("p").bind("click", function(e){
var str = "( " + e.pageX + ", " + e.pageY + " )";
$("div.htm").text("Click happened! " + str);
});
$("form.theform").ajaxForm({
clearform: true,
target:"#new",
success: function(response_text, status_text) {
var $inp=$("input.com").val();
var $inpa=$("textarea.comms").val();
$("input.news").val($inp);
$("Hello" + " " + $inp + " " + $inpa + "").appendTo("div.htm");
$("p.hide").hide();
$("input.com").val("");
$("textarea.comms").val("");
alert("ajx working");
alert(response_text);
$("Thanks for your sporthill order!").appendTo("p.inp");
$("div.shw").show("slow");
$('p.inp').fadeOut("slow");
$('#hide').hide();
}
});
});
view is:
def ajx_form(request):
if form.is_valid:
if request.is_ajax:
name = request.POST.get('name', '')
password = request.POST.get('password', '')
comments=request.POST.get('comment', '')
u=Users.objects.create(user=name, comment=comments)
return render_to_response('my_ajx.html',
{'username':name, 'comment': comments, 'request':request, },
context_instance=RequestContext(request))
return render_to_response('my_ajx.html', {'error':'You"ve got
errors', }, context_instance=RequestContext(request))
return render_to_response('my_ajx.html', {'error':'You"ve got
errors', }, context_instance=RequestContext(request))
Please let me know if you have a solution or any ideas. Thanks!!

Problems deserializing json object
I'm having difficulty deserializing a json object. I'm using django
appengine patch, so the models aren't the same as django's, but they
are very similar:
class Cust(db.Model):
custno = db.StringProperty(required=True)
company = db.StringProperty(required=True)
contact = db.StringProperty(required=False)
address1 = db.StringProperty(required=False)
address2 = db.StringProperty(required=False)
city = db.StringProperty(required=True)
state = db.StringProperty(required=False)
zipc = db.StringProperty(required=False)
country = db.StringProperty(required=False)
phone = db.StringProperty(required=False)
salesmn = db.StringProperty(required=True)
email = db.StringProperty()
def __unicode__(self):
return self.custno + " : " + str(self.company)+" : "+str
(self.city)+" : "+str(self.state)
class Cust_List(db.Model):
custno = db.StringProperty(required=True)
companies = db.TextProperty(required=True) #customer list as json
object
Note that the json object is stored in the db.TextProperty companies,
and is composed of more than a 1000 customers, all of which are also
individually stored in the model, Cust . I query the json object for a
customer list, since it saves CPU time on the appengine.
Here's what happens when I try to decode the json string object:
>>> from sport.models import Cust_List
>>> from django.core import serializers
>>> a=Cust_List.all()
>>> b=a.get() #returns the only and only data item in this model, which is a
>>> json object previously stored in the datastore.
>>> c=serializers.deserialize('json', b.companies)
>>> d=list(c)
>>> e=len(d)
>>> e
1057
>>> b
etc...
cy...@global.net", "phone": "269/552-", "state": "MN", "contact":
"Rick L
ee", "salesmn": "O1", "country": "", "address2": ""}}, {"pk": "XBwTAxc
hELEgpzcG9ydGNUYDA", "model": "sport.cust", "fields": {"city": "GOLD

"sta
te": "CA", "contact": "Randy Mintz", "salesmn": "H1", "country": "",
"address2":
""}}]')
>>> d
etc...
,
,
,
, , , , , , , ,
,
, , , , ,
, , , ,
, , ,
, ] etc.
Note that I just get returned a unicode representation of my model,
Cust. But the contact information, address information, and so on
disappears in the deserialized object. Any thoughts on why or what I'm
doing wrong?
Thanks for any help or ideas!

Problems with HttpResponseRedirect(reverse()) No match found
Hi,
I've read the django docs here:

admin error, cannot edit fields or delete records, url refers to incorrect primary key
I've set up a 'Reps' model in the admin. I can add records
successfully, but if I try to change a record or field, I get a 404
error. When I try to delete a record, I get this traceback here:
http://dpaste.com/750121/
My primary keys are integers, but it appears that the urls return them
as floats. Please see the example below.
The model in whl.models is as follows:
class Reps(models.Model):
prim = models.AutoField(primary_key=True, db_column='PRIM')
custno = models.CharField(max_length=50, db_column='CUSTNO',
blank=True) # Field name made .
company = models.CharField(max_length=50, db_column='COMPANY',
blank=True)# Field name made
#etc, etc.
class Meta:
db_table = u'whl_reps'
def __unicode__(self):
return self.custno + " : " + str(self.company)+" :
"+str(self.city)+" : "+str(self.state)
def get_absolute_url(self):
return "/%i/" % self.prim
My admin.py is:
from whl.models import Reps
class RepAdmin(admin.ModelAdmin):
fields = ('company', 'email', 'salesmn', 'city', 'state')
And for example when I click on a record to change it, I get a 404
error with a message "reps object with primary key u'39.0' does not
exist". In this case, when i click on a record, it returns this url
localhost/admin/whl/reps/39.0/
As you can see, the last primary key above is not an integer as it
should be. When I manually change the url to /admin/whl/reps/39/ I can
edit the record.
I'm using Django 1.4, mysql db on Ubuntu.
Any thoughts on why this is happening? Any help would be appreciated
very much. Thanks.

Re: Billing and invoicing app?
I'm not sure if there's anything that is django-specific. There are a lot of payment processing apps out there, including stripe <http://stripe.com>. I hear they provide a very good api libraries (including python), which would allow your to hook it up with Django. I don't know if this is what you are looking for, but I hope this helps.

Python 2.7+Windows 7+Django1.4 + Apache2.2 +mod_wsgi
For what it's worth, on Windows I like to use Apache2.2 for development purposes instead of the built in server that you have to fire up using the shell command, manage.py runserver every time you need it. On a Windows 7 machine, I followed the instructions to set up my apache server with django here: https://docs.djangoproject.com/en/dev/howto/deployment/modwsgi/ but I still had plenty of trouble getting it to work propertly. For example, I kept getting import errors in the log files such as, "no module name project.urls" in my wsgi script. Also, apache didn't serve my static files at all. I'm using django version (1, 4, 0, 'alpha', 0) In case anybody is having trouble with this setup, here is a blog that helped me get it working properly: http://pradyumnajoshi.wordpress.com/2009/06/09/setting-up-mod_wsgi-for-apache-and-django-on-windows/ This blog provides simple, detailed instructions on how to set up your apache httpd configuration file, where to download and copy your mod_wsgi file, etc. In addition, in my django.wsgi file, located in project/apache/ directory, I use the following: import os import sys sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../../"))) sys.path.insert(0, os.path.abspath(os.path.join(os.path.dirname(__file__), "../"))) os.environ['DJANGO_SETTINGS_MODULE'] = 'project.settings' import django.core.handlers.wsgi application = django.core.handlers.wsgi.WSGIHandler() I found the above at stackoverflow: http://stackoverflow.com/questions/5841531/django-mod-wsgi-apache-importerror-at-no-module-named-djproj-urls Note the above differs slightly from the official docs. Now it all seems to work properly. I got import errors when I simply used sys.path.append(path), where path was the absolute path to my project, instead of lines 4&5 above. Hope this helps someone who might be having trouble like I did. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django Baseball Site Model
You could create another field under Stat called team, and rename the class
stat to "Stint" or "Term" or "Session" ( I can't think of a better word )
to represent the stats of the player's "stint" at that team, that year.
You may also want to and another field to represent how many times the
player was traded that season, and in what order, most likely using an
integer field.
Ex:
class Stint(models.Model):
# some stuff here
team = models.CharField()
year = models.IntegerField()
traded = models.IntegerField() #if 0, then he wasn't traded, if 1
this is his 2nd team, etc...
Hope this helps,
Mac

Again, i can't reproduce your problem. It's working using SVN HEAD with your model and this view: http://dpaste.com/111590/. Could you try to use that dict and Student(**mydict) instead of "model_import_info.model_for_import.objects.create" ?

Although Malcolm is right about admin, this TypeError seems to me that
you forgot a comma before that line.
Something like:
urlpatterns = patterns('',
(r'^someurl/', 'someview') <-- *here*
(r'^admin/', include('django.contribute.admin.urls')),
)

If you need country_id/country_name:
>>> Profile.objects.values('country__id',
>>> 'country__name').select_related('country').distinct()
[{'country__name': u'Country1', 'country__id': 1}, {'country__name':
u'Country3', 'country__id': 3}]
Which run this query:
>>> Profile.objects.values('country__id',
>>> 'country__name').select_related('country').distinct().query.as_sql()
('SELECT DISTINCT "b_profile"."country_id", "b_country"."name" FROM
"b_profile" INNER JOIN "b_country" ON ("b_profile"."country_id" =
"b_country"."id")', ())

Also you can ommit select_related('country') which is implicit with
"country__name" and "country__id".

Wait. Do you know what "is_valid()" do, right?. :-)
is_valid refers to data sent to the form (for example request.POST),
not form itself.
For instance:
>>> f = UserProfileForm({'email':'a'})
>>> f.is_valid()
False
>>> f.errors
{'email': [u'Enter a valid e-mail address.']}
But:
>>> f = UserProfileForm({'email':'a...@a.com'})
>>> f.is_valid()
True

Re: Using forloop.counter0 on a variable
You can do that with a very simple template tag

@register.simple_tag
def get_element(list, index):
# You should catch IndexError here.
return list[index]
Template side:
{% get_element secondprice forloop.counter0 %}
