Re: Django Inline formset with jquery

[aRkadeFR]

Hello,

I got the same kind of probleme while working on the formset
couple days ago.

If this is related, the problem is the auto complete javascript that
doesn't go well with the jquery.formset.js.

You can add a function "added" in parameter of the formset function
for reloading the autocomplete widget.

something like:
```
|
$(function() {
$(".inline.{{ orderformset.prefix }}").formset({
prefix: "{{ orderformset.prefix }}",
added: function () { reload_auto_complete(); },
})
})
|
```

About the deletion, is it on the front end or the backend you're
talking about?

If this is front -> check your javascript
If this is backend -> check all the values dumping request.POST

Hope I was useful

Problem with submitting form in my django project! Urgent help required

[Ketan Bhatt]

I am facing a problem with my project, I posted about it on Stack Overflow, 
here is the link: 
http://stackoverflow.com/questions/28539441/reference-objects-using-foreign-keys-in-django-forms


Here is m code on github, I am currently working on the feature_forms 
branch: https://github.com/ketanbhatt/sketch-a-wish/tree/feature_forms


I will summarize my problem again, I am building a site in which users can 
login and make a wish. Other users can first a get a wish to sketch, and 
then submit the sketch they made for the assigned wish.

I have been able to create all the views and forms, except for the 
submitting sketch view. I want:

1. Only the wishes that has been assigned to the logged in user to be 
displayed in the Submit_sketch form

2. User selects the wish he wants to upload the sketch for, and submits.


Please help!

Re: ImportError

[aRkadeFR]

Two different problems here.

For your import of contactForm, please try the relative import like:
from contact.forms import contactForm
> contact is your app name

try the (absolute_import)[1] too if you're python2.

[1] https://docs.python.org/2/library/__future__.html

Let us know if this works

Re: Installare versioni successive

[aRkadeFR]

Hello there,

I think this is an English mailing list. From google translate, I
understood you want to upgrade Django 1.6 to 1.7.

Please read the following releases notes:
https://docs.djangoproject.com/en/1.7/releases/1.7/
more specifically:
https://docs.djangoproject.com/en/1.7/releases/1.7/#backwards-incompatible-changes-in-1-7

Check that nothing breaks, and then you can just upgrade
your version :)

Trouble changing from sqlite3 to postgres

[tony . guil35]

I have written a simple Django app (my first) that works with sqlite3 
database.
I want to change to postgres, but when I run the Django 1.7 migration 
utility  with the command
"python manage.py migrate"

I get the error:
psycopg2.ProgrammingError: column "date" cannot be cast automatically 
to type integer

Which is occuring in:
  File 
"/usr/local/lib/python3.3/site-packages/django/db/backends/utils.py", line 
65, in execute
return self.cursor.execute(sql, params

I am not sure how to track down the problem.
I am running Slackware Linux.

My models.py file is as follows:


from django.db import models
import datetime

# Create your models here.

class Location(models.Model):

   class Meta:
  unique_together = ("lat", "lng")

   lat  = models.DecimalField(max_digits=8, decimal_places=5)
   lng  = models.DecimalField(max_digits=8, decimal_places=5)
   name = models.CharField(max_length=200,  unique=True)

   def __str__(self):
  return "%s: %d %d" % (self.name, self.lat, self.lng)

class Observation(models.Model):

   date = models.DateField()
   location = models.ForeignKey(Location)
   observer = models.CharField(max_length=50)
   temperature = models.FloatField(default=0.0)
   photo= models.ImageField(default="tower.jpg", 
upload_to="uploaded_photos")

   def __str__(self):
  return self.observer
=

The DATABASE part of my settings.py file is as follows
where I have commented-out the old sqlite3 part:

-
DATABASES = {

#   'default': {
#   # sqllite3
#   'ENGINE': 'django.db.backends.sqlite3',
#   'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
#   }

   # For postgres:
#'django.db.backends.postgresql_psycopg2', 
# USER, PASSWORD, HOST also needed
# Inside postgres, "CREATE DATABASE database_name"

 'default': {
 'ENGINE': 'django.db.backends.postgresql_psycopg2',
 'NAME': 'app_1_db',
 'USER': 'bill',
 'PASSWORD': 'bill',
 'HOST': '127.0.0.1',
 'PORT': '5432',
 }

}


Please let me know if you have ideas.

Thanks.

confirm_login_allowed in subclassed authentication returns wrong error message

[Tomáš Sekanina]

Hello, 

I have a custom user model and I need to extend the user authentication 
during login and found this solution: http://bit.ly/1u705o9  It would work 
great for me and I ended up implementing this  . 
It works in a manner that it does not let such user log in, but raises a 
different error message which is: 'Sorry, that's not a valid username or 
password.'.  I tried posting this question on different forums but got no 
answer :(. It seems really simple so I do not see there a place for an 
error unless there is some problem with the custom user model. I will be 
glad for your opinion at least :).

Thank you in advance for any effort to solve this.

It seems like this works in practice, but this still looks like a

for a firmer foundation for ongoing work…

Re: confirm_login_allowed in subclassed authentication returns wrong error message

[James Schneider]

You should raise the error in your custom user login form when attempting
to authenticate the user, not directly from the custom user model or
authentication backend.

This is all covered in Djangos documentation...
https://docs.djangoproject.com/en/1.7/topics/migrations/#dependencies

Let me paste the relevant parts for you:

»Be aware, however, that unmigrated apps cannot depend on migrated apps,
by the very nature of not having migrations. This means that it is not
generally possible to have an unmigrated app have a ForeignKey or
ManyToManyField to a migrated app; some cases may work, but it will
eventually fail.

Warning: Even if things appear to work with unmigrated apps depending on
migrated apps, Django may not generate all the necessary foreign key
constraints.«

Well, no... please see below.


Let me paste the relevant parts for you:

This explains that unmigrated apps cannot depend on migrated apps.

My question is about the opposite case: Can migrated apps depend on 
unmigrated apps? I've explained the apparent problem in greater detail 
in my original post.

How to make a list-view sortable in frontend?

[ThomasTheDjangoFan]

Hi 'ya,

I am new to Django and would like to create a *sortable ListView* (just 
like the Lists in Django Admin) for an array of object-instances. The 
objects themself are *non Django-Models* and are pre-populated in an array 
before showing the view.

I've got a basic ListView working 
(https://docs.djangoproject.com/en/1.7/topics/class-based-views/), 
but the important question remains: *How do I make it sortable? *

Can you give me to some examples to check out how to implement a sortable 
ListView?

Kind regards and thanks a lot for your support
Thomas

Re: How to make a list-view sortable in frontend?

[James Schneider]

Are you displaying the data in a table? If so, I've always used
django-tables2, which includes the ability to have sorting in each of the
columns via a generated link in the header row of any or all columns
(up/down arrow, etc.).

Re: Trouble changing from sqlite3 to postgres

[Joel Burton]

The error is probably in code you wrote that uses the date field. Can you 
post the full traceback? That will let us see where the caller was that 
created the problem.

Form Wizard: how to send instance_dict based on the request

[Karim]

Hello mates!

I have some problems to understand how to set the view for
the NamedUrlSessionWizardView creating a instance_dict based on the user in
the request.

in my urls.py

url(r'wizard/new/(?P.+)/$',
ServiceCUWizard.as_view(
   FORMS,   # the list of ['form_name', form_object]
   url_name='service:new_wizard_step',
   done_step_name='finished',
), name='new_wizard_step'),

It works, I got all the forms as expected.

The forms are modelforms and I would like to bound the instance if is
possible, but I can populate it only using the request. I think I could do
that subclassing def __init__, but the instance_dict is a class attribute,
how I can populate it?

Thnak you

how to handle race conditions?

[Abraham Varricatt]

Hello,

I'm trying to make an app where folks can order X quantity of an item. The 
condition is that the order should only be made if inventory exists. Assume 
that we have stock of Y items. This means that only if Y >= X should we 
allow the sale to go through. And once we accept an order, the inventory 
should be updated so that Y = Y - X. 

The way I've currently implemented this is with a pair of getter/setter 
methods. I have a model 'ShopItem' which has two fields called 'quantity' 
and 'name' (this is unique). I've made a utility class (outside model 
source file) where I've made the following 2 functions;

def get_quantity(name):
  stuff_left = 0
  try:
item = ShopItem.objects.get(name=name)
stuff_left = item.quantity
  except ShopItem.DoesNotExist:
pass # return zero
  return stuff_left

def set_quantity(name, stuff_left):
  item = ShopItem.objects.get(name=name)
  item.quantity = stuff_left
  item.save()


Elsewhere in my project, if I need to display the remaining quantity of an 
item in a view, I'll pass the result from get_quantity(). At sale time here 
is how I update things;

def customer_buy(name, number):
  temp = get_quantity(name)
  if (temp >= number):
temp = temp - number
set_quantity(name, temp)
// do other things
  else:
// sale failed, do something else

I tested this on my system and things appear to work. But I'm concerned 
about race conditions. What if two different customers came in to buy the 
same item? As in; if I only have 7 items in stock, but one customer came to 
buy 6nos and another 5nos. There is a chance (as per my understanding) that 
both orders will be accepted - even worse, my inventory will not accurately 
reflect the updated situation. 

Any ideas on how this issue can be resolved? I've come across this 
- 
https://docs.djangoproject.com/en/1.6/ref/models/instances/#updating-attributes-based-on-existing-fields
 
, but not sure how to apply it to the current scenario. 

Learning django,
Abraham V.

[Petar Pilipovic]

Hello aRkadeFR.
I have solved mine problem, I was working whit Python 2.X here, and like

There was one other error, mine base.html did not render mine block 
content, because I did not defined it, I did that and now mine form is 
working.
Tank you.
Best.

Re: ImportError

[Petar Pilipovic]

aRkadeFR I have one other question regarding urls.py. I got this error when 
I am trying to go from contact or about to home page.


Using the URLconf defined in tryDjango.urls, Django tried these URL 
patterns, in this order:

   1. ^$ [name='home']
   2. ^about/$ [name='about']
   3. ^contact/$ [name='contact']
   4. ^admin/
   5. ^static\/(?P.*)$
   6. ^media\/(?P.*)$

The current URL, contact/{% url 'home' %}, didn't match any of these.

Now mine root/urls.py , and this is mine navbar.html 
, every other thing is connected properly, and I can 
go from home page to contact, about, but I can not go reverse.
Can you explain to me where is the error?
Tank you.
