Re: Accessing Django test client in setUpClass

[Fred Stluka]

Nicole,

If you can't access self.client of TestCase, you can always
allocate one yourself as:

c = Client()

See details in:

Namespace url lookup inside template of an app

[Thorsten Sanders]

Hello,

writing currently an app which should show different things based on 
namespace which is working already, but I do have problems with 
generating the right url inside the templates of that app.

I tried to use:
{% url 'myaddons:index' %}
but that always shows the same namespace url the last one attached.

Currently have defined inside that app:
urlpatterns = patterns('',
url(r'^$', 'myaddons.views.index', name='index'),
)

Then have 2 other apps in one I define:
urlpatterns = patterns('',
   url(r'^addons/', include('myaddons.urls', 
namespace='wow-myaddons', app_name='myaddons')),

)

in the other one:
urlpatterns = patterns('',
   url(r'^addons/', include('myaddons.urls', namespace='ws-myaddons', 
app_name='myaddons')),

)

The base one is:

url(r'^wow/', include('warcraft.urls')),
url(r'^ws/', include('wildstar.urls')),

With what I tried it always resolve to:
/ws/addons/

I want it to resolve to:
/wow/addons/ if called with /wow/
and
/ws/addons/ if called with /ws/

Greetings,
Thorsten

Re: Django web hosts in Canada

[Avraham Serour]

look for a vps and not a shared hosting, something like what you would get
with AWS

on the downside you will need to do everything yourself (installing and
configuring all the libraries, updating the server etc)

on the plus side it will be more flexible, it will support anything you
would like

Thanks for answering all my questions.

So it's perfectly save to call the save method at a later time? As long as 
I keep the object and a pointer to it in memory I can freely modify it in 
several Functions before finally calling save at some point in time?

Re: When do I have to call save() on a Model Instance?

[Vijay Khemlani]

You could pass the user as an optional parameter to function2.

Whether you should save the user or not in each of the methods depends on
the logic of your application, or you can add a parameter to the method
(True to save the object, False otherwise)

When do I have to call save() on a Model Instance?

[Tobias Dacoir]

I want to reduce the database queries, imagine I have a case like this:

def function1():
user = User.objects.get(id=1)
user.name ="Myself"
function2()
function3(user)
user.save()

def function2():
user = User.objects.get(id=1)
user.lastname = "private"

def function3(user):
user.age = 18

Even if this works (haven't tested it yet and I can imagine that at least 
function2() might be a problem), should I immeditately call .save() in each 
of those functions?

Or is it possible to freely modify the model and save it at a later stage? 
If so, function2() would not see the new value of user.name of course, 
however function3 should be able to see it (but probably not user.lastname).

Is there a best practice?

Django web hosts in Canada

[jogaserbia]

Hi All,

I would like to deploy my first Django website in the next month or so.  I 
am looking at deployment options, but need some clarification.

1) when id doesn't matter where the servers are

I understand that  in terms of PASS: heroku, AWS, and Google elastic 
beanstalk can all handle Django (python) and postres.

If I want to host on a 'normal' hosting service, which would be available? 
greengeeks just told me that they support Python but not Django, which 
confused me because I thought Django was fully written in Python, so I am 
clearly not understanding the complexities of deploying.  Also, they only 
use MYSQL databases, I wrote my first app using Postgres/POSTGIS as the 
database.

2) when I need servers in Canada

Due to privacy concerns, I may need to use servers that are exclusively in 
Canada.  I cannot seem to find any options on how to host Python/Django and 
postres on Canadian servers.  Does anyone have any pointers on that?


Any advice would be appreciated, as this will be my first run at deploying.

I have been through the heroku example, and it seems nice and easy to 
deploy and I can use Django and they use postgres.  

Ivan

sql query to annotation values e aggretate statements

[Mauro Ziliani]

Hi all.
My name's Mauro and I start to work with Django 1.7.3
I work on my project which tracks my accounting.

I need to translate a SQL query to annoteta values aggretate statements.

The application is named accounting

The models involved are:


class Nominativo(models.Model):
  nome = models.CharField(max_length=100)
  
class Impianto(models.Model):
  nome = models.CharField(max_length=100)

class Capitolo(models.Model):
  nome = models.CharField(max_length=100)
  

class Registrazione(models.Model):
  anno = models.PositiveIntegerField()
  impianto = models.ForeignKey('Impianto')
  nominativo = models.ForeignKey('Nominativo')
  capitolo = models.ForeignKey('Capitolo')

  dare = models.DecimalField(max_digits=10, decimal_places=2)
  avere = models.DecimalField(max_digita=10, decimal_places=2)


I need to translate te following sql statement

SELECT capitolo.nome, sum(dare) as uscite, sum(avere) as entrate 
FROM contabilita_registrazione 
INNER JOIN contabilita_capitolo as capitolo ON 
contabilita_registrazione.capitolo_id=capitolo.id 
WHERE anno=2014 
GROUP BY capitolo.nome 
ORDER BYcapitolo.nome;

How can obtain the same behavior using ORM?

Thanks in advance

MZ

Re: Best way to get ForeignKey Related Objects?

[Vijay Khemlani]

Python has higher order functions, so you can do things like this

m = pair.answers   # m refers to the method itself

print m# Prints "method AudioQuestionPair.anwers of ..."

answers = m()  # Actually executes the method

Re: Best way to get ForeignKey Related Objects?

[Vijay Khemlani]

"answers" seems to be a method on the AudioQuestionPair class, so your call
should be:

for answer in pair.answers():
print answer

and "pair.answers.get.all()" does not make sense sinse "answers" is a
method.

If you don't want to use a specific method, you can do this:

answers = pair.answer_set.all()

Best way to get ForeignKey Related Objects?

[Tobias Dacoir]

I have two Models as shown below. Now when I have a specific 
AudioQuestionPair and I do something like 

print pair.answers



it works just fine. However I can not do:

for answer in pair.answers



Using pair.answers.get.all() does also not work. So I have to do

answers = Answer.objects.filter(audioQuestionPair=pair)



Isn't there a better way to design this? I can imagine that using 
objects.filter is more taxing on the database and uses more time than maybe 
another method?


class AudioQuestionPair(models.Model):
audioData = models.ForeignKey(AudioData)
question = models.ForeignKey(Question)
database = models.ForeignKey(Database)
votes = models.PositiveIntegerField(default=0)

class Meta:
verbose_name = "AudioData-Question Pair"
verbose_name_plural = "AudioData-Question Pairs"

def answers(self):
return Answer.objects.filter(audioQuestionPair=self.pk)

def __str__(self):
return "Database %s: AudioData %s - Question %s with %s Votes and 
Answers: %s" % (self.database, self.audioData, self.question, self.votes, 
self.answers())

"""
 Answer for a specific Audio-Question Pair
 cumulative
"""
class Answer(models.Model):
body = models.CharField(max_length=255)
count = models.PositiveIntegerField(default=0)
isGroundtruth = models.BooleanField(default=False)
audioQuestionPair = models.ForeignKey(AudioQuestionPair)

class Meta:
verbose_name = "Answer to AudioQuestionPair"
verbose_name_plural = "Answers to AudioQuestionPairs"

def __str__(self):
return "%s - %s times" % (self.body, self.count)

Re: Forms test run on development database instead of test database

Thank you for the explanation. So I suppose a better way to do it whould be 
to provide initialize the choices in the DomainForm __init__?

Re: sending email

[James Schneider]

Couple things.

I think the return statement for thankyou.html needs to get kicked in a
tab, otherwise the form will show successful every time the form is
submitted, even if it had errors.If there are errors, it will also skip
your email code, but still show as successful.

This line is very confusing:

to_emails = [u.email for u in User.objects.filter(id__in=[a.'id'])]

I don't even think a.'id' is valid syntax. More to the point, your variable
'a' is populated a few lines earlier using a get() queryset, which means it
can only contain one item. That would render the list comprehension
statement (bad syntax aside) completely useless, since you would only ever
have a single element. That also makes the id__in filter unnecessary as
well.

Which leads to another question, are you expecting your User objects to
contain the same ID as your newleave objects (for example, User.id ==
newleave.id). That is indicated by the User.objects query you are making,
and I believe you may be incorrect there as well.

Without having seen the model, I'm guessing you want the list of
administrative users that are tied to a particular leave, your query line
would probably look something like this:

to_emails = [*a.admins.all()]

Also, in your send_mail call, you are encapsulating to_emails inside of
another list, like this send_mail(..., [to_emails]). Something tells me you
probably don't need to do that, since to_emails is already a list, but I
could be wrong there as well.

-James
