Django scheduling/calendaring
Hello Django developer, I have been assigned for my first real job as a developer. I have been asked to develop a *Learning Management System*. One of the components/apps this project must have is a way of managing training programs and projects and view them on a calendar. This is how my client wants it. However, I have never developed a calender before, so I did my research first on Django calendars. There are some tutorials online regarding this topic. But I also see there are a ton of ready to use Django Packages for this. So basically what I would like to know is if anyone has any experience with the Django calendar packages and would recommend me one. Thank you. -- You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Where to start - New to Django and Python

Using Django Sessions
Hello,
I am practicing for my college exams. I am building a Restaurant Order
System with Django and I am using Django sessions for the first. I borrowed
some ideas from the "Django by example".
Below you can find the MenuItem model and Order Model.
class MenuItem(models.Model):
category = models.ForeignKey(Category, related_name='menu_items')
# table ???
name = models.CharField(max_length=255, db_index=True)
slug = models.SlugField(max_length=255, db_index=True, default='')
description = models.TextField(blank=True)
image = models.ImageField(upload_to='menu_items/%Y/%m/%d', blank=True)
price = models.DecimalField(max_digits=10, decimal_places=2)
available = models.BooleanField(default=True)
added_on = models.DateTimeField(auto_now_add=True)
updated = models.DateTimeField(auto_now=True)
class Order(models.Model):
STATUS_CHOICES = (
('in behandeling', 'In behandeling'),
('klaar', 'Klaar')
)
# random_id = models.CharField(max_length=255)
table = models.ForeignKey(settings.AUTH_USER_MODEL)
item = models.ForeignKey(MenuItem, related_name='order_items')
price = models.DecimalField(max_digits=10, decimal_places=2)
quantity = models.PositiveIntegerField(default=1)
status = models.CharField(max_length=50, choices=STATUS_CHOICES, default='in
behandeling')
paid = models.BooleanField(default=False)
timestamp = models.DateTimeField(auto_now_add=True)
Below you can find a Cart class which handles adding, removing, iterating
etc. over the Menu Items using Django sessions. What I need is a function
in this class that only clears the items I have in the cart, but I still
need the total price. Right now I have the "clear" function which removes
the entire cart from the session. But since I am kinda confused on how to
do this I need some help.
from decimal import Decimal
from django.conf import settings
from menu.models import MenuItem
class Cart:
def __init__(self, request):
self.session = request.session
cart = self.session.get(settings.CART_SESSION_ID)
if not cart:
cart = self.session[settings.CART_SESSION_ID] = {}
self.cart = cart
def add(self, menu_item, quantity=1, update_quantity=False):
# Add a menu item to the cart or update its quantity
menu_item_id = str(menu_item.id)
if menu_item_id not in self.cart:
self.cart[menu_item_id] = {'quantity': 0,
'price': str(menu_item.price)}
if update_quantity:
self.cart[menu_item_id]['quantity'] = quantity
else:
self.cart[menu_item_id]['quantity'] += quantity
self.save()
def save(self):
# Update the session cart
self.session[settings.CART_SESSION_ID] = self.cart
# Mark the session as "modified" to make sure its saved
self.session.modified = True
def remove(self, menu_item):
# Remove a product from the cart
menu_item_id = str(menu_item.id)
if menu_item_id in self.cart:
del self.cart[menu_item_id]
self.save()
def __iter__(self):
# Iterate over the item in the cart and get the products from the DB
menu_item_ids = self.cart.keys()
# get thte product objects and add them to the cart
menu_items = MenuItem.objects.filter(id__in=menu_item_ids)
for menu_item in menu_items:
self.cart[str(menu_item.id)]['menu_item'] = menu_item
for item in self.cart.values():
item['price'] = Decimal(item['price'])
item['total_price'] = item['price'] * item['quantity']
yield item
def __len__(self):
# Count all the items in the cart
return sum(item['quantity'] for item in self.cart.values())
def get_total_price(self):
return sum(Decimal(item['price']) * item['quantity'] for item in self
.cart.values())
def clear(self):
# Remove cart from the session
del self.session[settings.CART_SESSION_ID]
self.session.modified = True
And below here you'll find the view that handles saving the items in the
request cart in to the Order model. Instead of calling the cart.clear()
function I need to call a function that removes the ordered items from the
cart while still having the total price in this session.
@login_required
def create_order(request):
cart = Cart(request)
if request.method == 'POST':
for item in cart:
Order.objects.create(table=request.user,
item=item['menu_item'],
price=item['price'],
quantity=item['quantity'])
cart.clear()
return render(request, 'orders/order_success.html', {'cart': cart})
return render(request, 'cart/cart_detail.html', {'cart': cart})
I hope my question is clear and someone can help me with this.

GET parameters in admin "add" model page
I noticed that django admin "add" page reads GET parameters and uses them as initial values in the form. However I was not able to pass DateTime values in this way.

Re: import
Hi Johan, I don't know if you put sometime into learning python. These imports are a way to reuse other modules that already provide some of the functionality that you are trying to achieve. To know the right module to import from and to select the right things to import, you should consult that package's documentation.

Or, the problem could be that you have to restart gunicorn sudo supervisorctl restart [gunicorn-program-name] if you changed media root and static root settings then you have to point nginx to the right location of those assets in nginx site configuration. i.e. in the file that you create inside /etc/nginx/sites-enabled/ for your app. Hope you can resolve it.

count resulting rows in sliced valuesqueryset
Suppose I have a queryset qs. For paginating purposes I need to do
something like:
count = qs.count()
qs = qs[0:100]
Unfortunately this executes the query twice, which I don't want.
I can use postgresql windowing function like that:
qs = q.extra(select = {'count': 'COUNT(*) OVER()'})
to get the 'count' attribute on every object. So far this is very nice. The
problem is that my queryset qs is actually a ValuesQueryset, i.e. a
queryset build with .values(...).annotate(...). In this case the extra
select field is ignored (as reported in the documentation). This makes
sense because even in postgres it seems not possible to mix window
functions with "group by" clauses. The solution with raw SQL is the use of
a subquery. I can get the correct results with the following query, where I
enclose the sql produced by django in a subquery:
sql = 'SELECT COUNT(*) OVER() , subquery.* FROM (%s) AS subquery' % qs.query
Now the questions:
1. in this snippet qs.query is converted to string. The documentation says
that parameters in the resulting query string are not correctly escaped, so
maybe I should take care of SQL injection? How do I get correct escaping of
parameters?
2. Is it possible to re-attach the sql statement to my ValuesQuerySet? To
keep the rest of the code unchanged, I need to modify qs so that it
executes the new raw query. However I don't see how to construct a
ValuesQueryset with a raw SQL code...
E.

Re: Social networking site
if you are looking a ready made solution I suggest using ELGG - which is not Django by the way but a working solution in PHP or Dolphin.

Re: consistent (un)capitalization in form labels
I know I can use the label argument in every field. However this is
very annoying... also this is very complicated for ModelForms where
labels come from Model attributes, and the verbose_name of these
attributes is not useful since it gets capitalized.

consistent (un)capitalization in form labels
Hi all, my graphic design prescribes that every label in html FORMS should be not capitalized and without any suffix. For example, a "my_date" field should be rendered as: my date To achieve this I need to set a "label" attribute in every Form. For ModelForm (Forms automatically created from models) my only possibility is to rewrite the entire form "by hand" in the HTML template file. Is there a better way to achieve this beahviour? Is it possible to redefine the function used to convert the field name to the field label? E. -- You received this message because you are subscribed to the Google Groups "Django users" group.

ValidationError to error message
I cannot understand the following behaviour:
>>> from django.core.exceptions import ValidationError
>>> str(ValidationError('so and so'))
"[u'so and so']"
>>> str(Exception('so and so'))
'so and so'
How do I convert a ValidationError to a str for composing a human
readable message? Even if ValidationError is derived from Exception,
its conversion to str is different... what is the right way to get the
message in a ValidationError?

all data of all manyToMany relations lost!
Dear experts, today I was inspecting the ManyToMany relations in the _meta subclass of a Model class of my database. At some time I realized that all data associated to such relations was lost in the database! The corresponding tables are empty. Other fields and relations are ok. I suspect I have issued some command (working from the shell issued with manage.py) which erased the field form the data model and consequently all the corresponding data has been deleted.

another tutorial for polls...
Hi all, Following the announce of some tools of mine (obviews)... I've just add a practical example, inspired from django tutorial on polls. The theory is on a standalone page describing the views used in this simple poll application (http://www.obviews.com/polls/)... Anyhow, somones need a few less theory and a bit more show... so you will find the real polls on http://polls.obviews.com, with (as you guessed) real stuff like polls and choices and votes (and code too). Keep in mind the demo is very simple, its purpose being more a demo... than a poll app :) Any feedback welcome !

Re: Initial values and unbound forms (apparently a bug?)
Hello, I would say that the behavior you have is normal. Quoting the doc "Using initial data with a formset: Initial data is what drives the main usability of a formset. As shown above you can define the number of extra forms. What this means is that you are telling the formset how many additional forms to show **in addition** to the number of forms it generates from the initial data." What I understood from the doc is that initial values are used for existing objects or ones being built. Ie, if you provided 6 forms with default values in a formset, you will end up with 6 new objects created/modified. It's up to you then to really create/modfiy those objects. Consequently a solution for you would be to set extra=0 and set up you inital datas as you have done but not create objects if default values have not been changed (for instance).

[ANN] obviews: object oriented views
Hi all, My first post to share an habit of mine that you might find useful: it deals with views and wraps them into objects. I have replaced the functions with objects for a while now, found it very handy and add pieces of code here and there in my little home- land, but never shared it. Which might be common, but still not really grateful. So I am refactoring all bit by bit and making some releases when I feel its readable. The starting point if you are interested could be on www.obviews.com, a demo web-site that will replace any long speech.

I already did that and more before asking the question. 1. The link to Jack Slocum blog in that page is broken. His new blog/ site no longer has that type of commenting system. 2. Extjs does not provide old versions of their code for download. Their new version is licensed in a very messy fashion making it impossible to use in almost any project without buying their commercial license. Some info on that can be found at http://pablotron.org/?cid=1556. They also claimed that extjs licensed under LGPL was not actually LGPL and should not be distributed. I think the version used on djangobook.com was based on the BSD/public domain licensed initial extjs which is free of all this mess. 3.

Re: Update database field
Hi, This is what i ended up doing in a project of mine.But this involved two DB calls One to retrieve and another to save, but with just SQL can be accomplished in a single UPDATE statement. Django docs menthion that if you explicitly specify an id (primary key ) it should update the db. So I did something like this i = Item.(id=4, name='New Name') i.save() The Item model has a created_at column, which is sent NULL if I do this. Hence the query fails. There shoud be a better way of doing it. -- Manu On 11/14/06, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > Yea, that will work. > > Get the "thing" > change the value > store it. > > > tinti wrote: > > Got it: > > > > update = Queue.objects.get(message=message_id) > > update.read = 1 > > update.save() > > > > I thinks this is the correct way, if not somebody can advise me another > > ;) > > > > On Nov 14, 11:37 am, "tinti" <[EMAIL PROTECTED]> wrote: > > > Hi all, > > > I need some help updating a database field.

Yes, this is the functionality that i'm seeking. The id of the object most recently saved on a per user(connection) basis. In case of MySQL (5.0) the id is unique to connection. Here is the relevant portion frrom the docs "For LAST_INSERT_ID(), the most recently generated ID is maintained in the server on a per-connection basis. It is not changed by another client." Don't know about pre-5.0 versions, but i guess it is the same. > > The easiest way to get the last inserted id is to create an object, > save it, then read its id directly. If you need the maximum inserted > id, use select max(id) from table. To do this you should be using the create method and not the save method since the save does not return the object saved. p = Person.objects.create(first_name="Bruce", last_name="Springsteen") p.id will give you the id of the object saved.
