DB based translations?

[Joshua Russo]

Ok, I've been looking into the different database based translation 
solutions out there and I can't find what I really had in mind. I need to 
have non-technical people easily update the translations. So I wanted a 
solution where I could create an interface to ease the process.

One problem is that none of the solutions seem to talk about translating 
static text. I'm thinking I need to create a site_content table to handle my 
static text translations and then use one of these solutions against it. 

If this is an appropriate solution, what are people's experience with the 
different database driven translation solutions? I tried 
django_multilingual, and django_multilingual_ng but they seemed to have 
issues with South. (Of course that was a few months back and I can't 
remember the exact problems I was having.) I'm now looking at 
django_modeltranslation, but none of these products really give the 
impression of being production worthy.

I'm willing to give them a shot because I need something and it's small 
enough project that I can take a little more risk. What are people's 
experience with them?

Thanks in advance
Josh

also read something about normal forms, as your question is not so much
django related as rdbms related. Hint: look at foreign keys.

Re: Django beginner question

[Christian Ramsey]

Hi and thank you so much,  this provided a ton of clarity, especially
the modelling of the order table with a foreign key to a user, I was
locked on thinking the user table needed to somehow have the orders
within it. But I see I needed to step back.

I've already started to implement all of this and I am trying to
understand the  additional table, if the Order table already contains
the user it belongs to, then what will the additional table be set
for, from my perspective would this be to keep the original order?

Thanks so much again.

I guess you could already start with the products and the users.
This is what yuou need in any case and which allows you already to learn
qutie some django.
- Create the User and product Models and create either your own views or
admin views such, that you can populate the Users and Product database.

Then you could work on the view allowing a logged in user to select
products to be put in the shopping cart.

Only then you had to care about how to implement the shopping cart.

I never implemented a shopping application and  what I suggest is very
probably neither the most elegant nor the most efficient solution.
But what is clear is, that you should use at least one table more.


Example Suggestion:

User: contains info about the user

Product: info about a product and it's price (though price might be in a
separate table)

Order: Info about the order, which could be ForeignKey to a user, the
order date, and perhaps payment status.

And one table more, which would store one entry of a order:
it would store a oeign Key to a Product, the selected amount and a
ForeignKey to the order it belongs to.

Hope this gave you some ideas of how to get started.

Re: Django beginner question

[Shawn Milochik]

Christian,

We understand that you're a beginner, and there are a lot of people that 
are willing to help people new to Django on this list. However, you've 
basically laid out an assignment here and asked how to go about it.


That comes across as asking others to do your work for you. You won't 
find much assistance when you give the appearance of being either 
incompetent or lazy, which is how this comes across.


The best way to learn is by doing, so go start your project. Get as far 
as you can, and when you have a specific question explain how you got 
stuck and what you tried to fix it. Then I'm sure you'll get useful replies.


Please read the "Prepare the question" section here:
https://code.djangoproject.com/wiki/UsingTheMailingList

Your initial e-mail violates nearly every tip listed. That list was 
compiled specifically to allow people who want help to get the most out 
of this list, and for those who enjoy helping others to avoid wasting 
their time.

Django beginner question

[Christian Ramsey]

Hi I am a Django beginner and I am just getting into creating apps
with it, my goal was to create a simple
order application for practice. The app will be somewhat like this:

1.A user will login or create an account.
2.A user will order from a list of items and depending on the item it
may have size and/or type, some will have preset sizes and no type at
all.
3. Upon purchase which for this demo will not have a monetary system
integrated, so as a replacement it will email the admin email with the
details and also display the order to them for printing once they are
finished.
4. The user will be able to check his/her orders in which the admin
will be able to set to pending or shipped to each order
5. The admin will also be able to view all orders from every user and
delete, edit, mark the details of the order.

Pretty straightforward I thought but I can't seem to wrap my head
around the models mostly and especially the product table.

For the products would I be creating an array of different orders and
a separate array of sizes in the controller and assigning that to the
form?

My 3 classes in my model are currently Users, Products, Orders
I am not sure how a order from the products is assigned to a user in
the database,
does the Users class need to have both products and orders inside of
it as a one to many for both?

So when I create the form that submits this information how does it
assign that order to that product to that user?

Admin TabularInline collapsed fieldset missing expand button

[Lee]

I need to display TabularInlines for multiple related tables and have
them all initially collapsed. I overrided admin/edit_line/tabular.html
and added the "collapsed" class to the  element. This
collapses the fieldset alright, but there is no button/control to
expand it. I've googled for hours and see related posts but no
solution.

Thanks for any help.

Re: What I am missing is this Django "logout"?

[Subhranath Chunder]

> Welcome {{ request.user.username }}. Logout

This part of your code is generating a logout URL like this in your
template: "/logout/directorio"
Now, your urls.py has the pattern:
url(r'^logout/(?P.*)/$',
'django.contrib.auth.views.logout', name='auth_logout_next'),

This makes, the variable 'next_page' assign the value after the slash
'login/' section. i.e. next_page = 'directorio'
Now, the logout view is invoked and it's code gets executed. But since you
provided a relative url value to this view, a http 302 is issued to the
client to fetch the new url. Formed as a result of joining you current url
and the relative path. i.e. '/login/directorio/directorio'. Which is
basically again matching with the last url pattern. So, this whole thing
keeps on going in a loop where:
'/logout/directorio' is requested the first time. In response, the client is
requested to fetch url,
'/logout/directorio/directorio' the second time...
'/logout/directorio/directorio/directorio/directorio' the third time...
and so on and on in a loop.

This is why you never see the expected output in the page. The actual logout
is done in the first request only.

So, when you refresh the page, you are basically pre-empting your browser
client to break the initial loop, and manually requesting for the new fetch
request.

I hope I was able to clear the reason behind the outcome you were
experiencing.

Re: extending the User profile - which way to go?

[Subhranath Chunder]

My suggestion, do it the Django way. In any case, even if you use the
inheritance model, the additional data would be stored in a separate
database table, and the data belonging to the super-class would be stored in
the main user's database table.

extending the User profile - which way to go?

[Axel Bock]

Hi again,

I will need to add some properties to a user in the future. Now I found two 
ways of doing it. First, the Django-way (as described in the Django docs). Then 
I found some other posts from other people, all doing an inheritance of the 
original User-class and using this one. That seems rather elegant, cause there 
is one database lookup less necessary per user lookup. Now I want to go a way 
which is most "Djangonic" - cause I don't want to be stuck somewhere in the 
future with something that breaks on Django 1.4 or whatever.

Any recommendations from the users here? 


Thanks in advance!

This sounds like a huge duplication of effort: there's already Twig[0],
a port of Jinja2[1] which is basically a reimplementation and extension
of Django's own templating language.

So, basically, if people want Django's templates in PHP they can
already use Twig.

Because there's only one digit in the month (7), and it's expecting two. 

Either change your code to pad the month to two digits, or change the regex 
to /(?P\d{1,2})/$

Re: I need help with reverse and url patterns

[Joshua Russo]

Never mind I got it. I changed my url patter to 

url(r'^events/(?P\d{4})/(?P\d{1,2})/$', events, 
name="eventsMonth")

I'm still not very sharp on my regex skills. I realized that {2} required a 
2 digit number

I need help with reverse and url patterns

[Joshua Russo]

I setup this patter in url.py

url(r'^events/(?P\d{4})/(?P\d{2})/$', events, 
name="eventsMonth")

in my template I have this tag

{% url eventsMonth year=month.prev.year month=month.prev.month %}

but I keep getting 

Caught NoReverseMatch while rendering: Reverse for 'eventsMonth' with 
arguments '()' and keyword arguments '{'month': 7, 'year': 2011}' not found.

I traced the problem into the reverse() code and the logic goes all the way 
to the end, when the following statement from line 325 of 
core/urlresolvers.py fails and I can't figure out why

if re.search(u'^%s' % pattern, candidate, re.UNICODE):

The pattern is 
'events/(?P\\d{4})/(?P\\d{2})/$'
and the candidate is 
u'events/2011/7/'

Why doesn't that regular expression match? What am I doing wrong?

Did you copy admin static files to your static path? They are stored in
{DJANGO_ROOT_DIR}/contrib/admin/media . You need to copy all of them to
{YOUR_STATIC_ROOT}/admin

Re: Specific models without a database table

[sedl...@gmail.com]

Hi,
you may use custom model manager (responsible for retrieving objects
from DB) and custom save method (which would not call Model.save),
together with managed=True.

You may still face some issues, however I think this should be
possible.

Cheers,
Filip

Django Admin - relationship between different models

[Petey]

Hi,

I have two models:
- Publisher - my main model
- Images - additional model for images
http://pastebin.com/VUNCzDye

In images model I have a link generator which displays absolute path for 
uploaded images.

I use inline to add images for messages. I want to display admin_tumbnail 
function as readonly_field and list_display in my news.

How I can do it?

View-Voodoo: Calling functions in a view does weird things

[Axel Bock]

Hi all,

I am new to this list (hello btw :), a beginner of Django, and I have
discovered a _very_ strange thing. Basicall I have a view handling a
file upload (see shortened code below). Depending on a select field a
function gets called handling the stuff, and returning. (rtr =
render_to_response). Now. The handler function sets a message.

That does not work.

But. If I copy-and-paste the code of the function
"call_my_other_function" into the if-block in myview, it does.

I don't get it - at all. Can someone please explain?

Thanks in advance & greetings,
Axel.


def myview(request):
if request.method =="POST":
call_my_other_func(request)
else: rtr("index.html")

def call_my_other_func(request):
# do something with the data
messages.info(request, "hello world")
return rtr("index.html", context_instance=RequestContext())

It reports you're missing the key "username" from your POST... so the first 
thing I'd check for is ... do you have a line like this in your login

Model Inheritance and methods

[CrabbyPete]

I have the following models:

class Deal(models.Model):
"""
Deal is a deal for  Interest. There should only be one
deal for each Interest pair
"""
interest = models.ForeignKey( Interest )
max_sell = models.IntegerField(default = 1)

def terms(self):
return self.term_set.all()

class Term( models.Model ):
"""
A Term are the terms of a Deal. There can be many Terms for each
Deal
"""
deal  = models.ForeignKey( Deal )
canceled  = models.BooleanField(default = False)
cost  = models.CharField( max_length = 10, blank = True, null
= True )
buyer = models.ForeignKey( User, blank = True, null = True )

def execute(self, **kwargs):
pass

class Expire( Term ):
"""
Subclass of Term that is good until an expiration date
"""
date= models.DateField()

def execute(self):
if self.buyer == None or self.canceled:
return False

delta = self.date - date.today()
if delta.days >= 0:
return True
return False

def __unicode__(self, **kwargs):
return ''

class Cancel( Term ):
"""
Subclass of Term that the Term is good until canceled
"""
def execute(self):
if self.buyer == None or self.canceled:
return False
return True

def __unicode__(self):
return ''


I want to do the following:
for term in deal.terms()
 if term.execute():
do something


My thought was the term.execute method would be overridden and the
type of term, either cancel's or expire's execute method would occur,
but it only executes the term.execute()

I can get around it by having the following as the term execute, but
its ugly
def execute(self):
try:
   term.cancel.execute()
except:
   pass
try:
  term.expire.execute()
except:
   pass

Any suggestions?

I hear this a lot that "things will break" if you subclass User. However, I

Re: Django Test Corrupted Test Data

[Malcolm Box]

According to the SO post, you're seeing TestObject.objects.all().count()
return two different values on successive calls.

That is basically impossible unless there's something else getting in there
and doing stuff to your db.

Alternatively, does your subclass of TestCase correctly call
super(MyTestCase, self).setUp() and other superclass methods to get the DB
setup right?

You'll need to use the low-level cache API to invalidate the individual
cache entries. Hook up a post_save handler to your model, figure out the
key(s) for the views affected and use cache.delete() to remove the entry.

Yes, it's possible. You want the "managed" attribute on the model - see
https://docs.djangoproject.com/en/1.3/ref/models/options/#managed

This will prevent Django from creating or modifying the db table

That is substantially harder, but could be possible. The main problem is
that the Django ORM will want to write SQL queries when there's a link to
the EmailAccount model.

Your best bet is probably a proxy model that contains a reference to the
relevant API record (e.g. the email address identifier or whatever the API
uses), and then a custom save() method that writes the values out to the DB.
You can use the Django form logic etc without it needing to be backed by a
model.

It will largely depend on how you want the EmailAccount to look - the closer
you want it to work to a standard ORM model, the more work you'll have to do
to trick things. If it's a simple field that isn't used for queries, then
you could look at creating a custom field type that knows how to read/write
the values to the API.

All the above advice is worth exactly what you paid for it!

What I am missing is this Django "logout"?

[Andre Lopes]

I am new to Django, and I am trying to put the logout to work...

I have installed the an App called, Django-Registration.

My problem is that I can do the logout, but the page does not get
refreshed, I must to press F5 after the logout to see the page for not
logged users.

What I have done is the following:

urls.py, added to urlpatterns:
[code]
url(r'^logout/$', 'django.contrib.auth.views.logout', {'next_page':
'/'}, name='auth_logout'),
url(r'^logout/(?P.*)/$',
'django.contrib.auth.views.logout', name='auth_logout_next'),
[/code]

In the template I have this code:
[code]
{% if request.user.is_authenticated %}
Welcome {{ request.user.username }}. Logout
{% else %}
Welcome. Please login or register
{% endif %}
[/code]

When I click Logout I dont see this in the screen:
[code]
Welcome. Please login or register
[/code]

I only see this text if I use F5 to refresh the page.

What I am missing here?

Please give me a clue.
