Re: Use 3rd party django package in my own project (PYTHONPATH)

[Mario Gudelj]

Have you looked at
https://django-model-report.readthedocs.org/en/latest/installation.html ?

After you add it to "INSTALLED_APPS" (I guess that's what you meant by
adding it to 'Installed_Packages') you need to create reports.py etc. The
instructions on RTD are pretty good...

Re: Switching settings, in a non-webapp?

[Doug Blank]

This ended up being just a simple Python3 issue, and the solution below
works fine, as far as I can tell so far. I post it here in case anyone
finds it useful:

I defined a "modules checkpoint" to which I can roll back to:

>>> from modules_checkpoint import ModulesCheckpoint
>>> checkpoint = ModulesCheckpoint()
>>> from gramps.webapp.databases.database1 import database
>>> database.dji.Person.all().count()
4
>>> checkpoint.reset()
>>> from gramps.webapp.databases.database2 import database
>>> database.dji.Person.all().count()
0
>>> checkpoint.reset()
>>> from gramps.webapp.databases.database1 import database
>>> database.dji.Person.all().count()
4

(showing the different counts in two different Django databases, defined in
different settings.py). Code is below.

-Doug

# modules_checkpoint.py
import sys
class ModulesCheckpoint(object):
def __init__(self):
self.original = sys.modules.copy()

def reset(self):
# clear modules:
for key in list(sys.modules.keys()):
del(sys.modules[key])
# load previous:
for key in self.original:
sys.modules[key] = self.original[key]

Re: Defining base templates for reusable apps

[Some Developer]

On 09/05/15 11:47, Bruno A. wrote:

Hi,

I've never done it, but I myself want to do a similar thing, so I've
been thinking about it a bit. The solutions I've thought of are the
following:

  * Template inheritance, as you mention. You provide the base template,
but it might not be straightforward for the app's user to override.
The Django's admin is a good example of this, and it can be
customized partially or entirely by adding an admin directory in
your site's templates directory, there are also some apps providing
new interfaces
 entirely.
  * Use the include tag

to let your app's user define the main site canvas and just generate
some basic HTML in the middle of their page, with their navbar,
footer...
  * Along the same lines, provide in your apps custom template tags for
the CSS, the JS you need and the content of your pages.

Now, I guess it depends on the complexity of the content your app
provide, whether you need parameters, etc...



Yeah I'll have to think about this some more. In all my previous 
projects I have just used straight up template inheritance but in those 
projects I haven't had to worry about a user needing to customise the 
look and feel of the site.


By providing a base template it makes the project easier to develop but 
I also think it makes it harder to customise by other users of the 
project as they have to plugin in their own base template and create the 
required blocks for the other templates to inherit from.

Thanks, but I think you have misunderstood... there is no http service...
this is not a web app... only Python is involved. I need to reset the

Re: Switching settings, in a non-webapp?

[David Sieger]

If restarting the whole http service is an option, you could think about
a setting up a separate service that is capable of stopping/starting
your http service. You could then order this new service from within the
http service to restart the http service with a different settings
module. (I'm thinking ZeroMQ, but there are definitely other ways to
implement this.)

Use 3rd party django package in my own project (PYTHONPATH)

[Kasra Khosravi]

i am creating a susbcription management system and I want to use a third 
party django package for reporting :

https://github.com/juanpex/django-model-report

Since I am new to django, I'm not sure how to use it, First I install it 
using pip (I have also tried installing it using setup.py), after that I 
think I have to add this package to my PYTHONPATH but I have no idea how to 
do it.

After doing this, when I put that package under "Installed_Packages" in 
django settings.py, Nothing happends.

i was wondering if anybody can help me with this?

Re: Two questions on Django Tutorial.

[Tim Graham]

You are using Python 2, but the tutorial is written for Python 3 as noted 
in part 1. If you aren't willing to switch to Python 3, you can rename the 
__str__ method to __unicode__ as the comment indicates.

Two questions on Django Tutorial.

[SUBHABRATA BANERJEE]

Dear Group,

I am very new to Django, and started with Django on Windows. I am using 
Python 2.7.9. I have some 
issues learning it. 

(a) I was following the Tutorial given in 
https://docs.djangoproject.com/en/1.8/intro/tutorial02/
It is generally going fine I am using, 1.8.1 of Django as given in 
>>> django.get_version()
'1.8.1'
Here as I gave 
python manage.py runserver
I could find the login page, http://127.0.0.1:8000/admin/ and could login 
using my login id and password.
But as I changed the admin.py with admin.site.register(Question) I could 
not find the changed view of the login page, rather it is 
not coming anymore.

(b) I was trying to follow the earlier part of the Tutorial given in,
https://docs.djangoproject.com/en/1.8/intro/tutorial01/, things were 
generally fine, 
but somehow I am failing to follow, 
def __str__(self):  # __unicode__ on Python 2
return self.question_text
in models.py, I am not being able to write models.py
So, if I use it as,
In [12]: Question.objects.all()
Out[12]: []

In [13]: from polls.models import Question, Choice

In [14]: Question.objects.all()
Out[14]: []

In [15]: Question.objects.filter(id=1)
Out[15]: []

In [16]: Question.objects.filter(question_text__startswith='What')
Out[16]: []

In [17]: from polls.models import Question, Choice

In [18]: Question.objects.all()
Out[18]: []

In [19]: Question.objects.filter(id=1)
Out[19]: []

I am not getting the desired output.

If any one may kindly suggest what is the error I am doing.

Thanks in advance,
Regards,
Subhabrata Banerjee.

DjangoCon US 2015 Proposals Deadline

[Andrew Pinkham]

There are only 4 days left to submit a proposal to DjangoCon US 2015 
!

We want to hear about your experience with and around Django. However, talks: 

- Don't need to be about Django specifically
- Don't need to be 100% fleshed out.
- Don't need to be purely technical
- Don't need to be advanced

The conference isn't until September, so if you have a kernel of an idea, 
submit that! 

Never spoken before? Not a problem! There are speaker mentors that will help 
you .

Is cost a concern? Not a problem! Apply for financial aid 

 (deadline also May 15th for speakers).

There is no reason not to apply! Here are two articles to get you started.

- Writing a PyCon Proposal by Brian Curtin 

- How to Submit a Kickass Talk to otsconf (or any other conf for that matter) 
by the OpenTechSchool Conference 


As always, feel free to contact us !

Submit your proposals soon, and we hope to see you at DjangoCon US!

Andrew

Switching settings, in a non-webapp?

[Doug Blank]

Django users,

We are using Django for two purposes: its ORM for a single-user desktop
app, and for a regular Django webapp.

For the desktop ORM, is there a way to switch between different
settings.py? For example, we'd like to be able to load the default
settings, but then later unload everything, and load different default
settings.

Looking for something like unloading/reloading all of the relevant
sys.modules.

We're using python3 if that matters.

Thanks for any suggestions/pointers!

SETTINGS Error

[SUBHABRATA BANERJEE]

Dear Group,

I am pretty new to Django. I was using 
https://docs.djangoproject.com/en/1.8/intro/tutorial01/ to learn aspects of 
Django.
As I gave the command in IDLE, 
from django.db import models

I am getting the error as,
Traceback (most recent call last):
  File "", line 1, in 
from django.db import connection
  File "C:\Python27\lib\site-packages\django\db\__init__.py", line 11, in

__getattr__
self._setup(name)
  File "C:\Python27\lib\site-packages\django\conf\__init__.py", line 46, in 
_setup
% (desc, ENVIRONMENT_VARIABLE))
ImproperlyConfigured: Requested setting DATABASES, but settings are not 
configured. You must either define the environment variable 
DJANGO_SETTINGS_MODULE or call settings.configure() before accessing 
settings.

I tried to do some research on the problem in internet and did not find 
anything much of use.

I am using Windows 7 Professional, Python 2.7.9 and IDLE as GUI. I am using 
>>> django.get_version()
'1.5.4'
as my django version, and learnt more or less how to use command prompt as 
given in this tutorial.

If anyone may kindly suggest how to solve the problem.

Regards,
Subhabrata Banerjee.

Re: percentage or number data entry solution please

Your other option is to provide functionality in the clean method to
convert "33.3%" (which is a string ) into 33.3 (numeric) and then store
the numeric value into another field... but that is messy.  I would
rather have my label say, for example:

Score(%): 

which is linked to a numeric only field.  And then have the form raise
an error (custom if need be) on that field if the user tries to enter
33.3% rather than 33.3  (sometimes users have to be willing to learn as
well :)


Which is what I am doing ... and will keep doing until there is an 
enhancement along the lines of a DecimalField arg/kwarg which lets the 
form accept a % sign but throws it away.


I have added some help text which explains what to do.

Thanks Derek

In the Admin I want the user to be able to enter a decimal number

At the moment DecimalField barfs if the user enters a human style
percentage sign.

My initial thought is to change it to a CharField and muck around
making
an awful mess behind the scenes to get - and store - the 0 to 100
decimal value I really want.

On the other hand, there is a snippet ...

https://djangosnippets.org/snippets/1914/


... which looks promising but I'm not sure how to get that into the
Admin

I have seen Django Extras has a PercentField but that seems to be a lot
of stuff to solve a small "simple" problem. Also, I haven't seen where
to slip it into the Admin

There is a ticket #17662 (now closed 'wontfix') but that focuses on
doing conversions which isn't what I'm after.

Here is another approach based on the snippet quoted above ...


http://stackoverflow.com/questions/6690692/problem-rendering-a-django-form-field-with-different-representation




... and which draws a suggestion to use a MultiValueField. I didn't try
too hard to understand the Django docs on MultiValueField because if
that is the answer I'm trying to fix the wrong problem.

I just want to ignore the percent sign if the user sticks it into a
DecimalField.

Thanks for any ideas

Mike

Show the code. All you have shared so far is that you are using the

What storage engine are you using with mysql? MyISAM is
non-transactional; it accepts the SQL statements for transactions, but
always operates in autocommit mode.

Re: Sending Data from client side(another computer) to Django(my computer) using Socket library

[Guilherme Leal]

Puting plain, you just need to execute a POST request on the client side.
That makes aviable the content on the request.POST property on your client
side view.

Wich tecnology you use to make the post request doesnt matter. The only
thing you need to keep in mind is when you "navigate" through your browser,
you're making a GET request, not a POST. Thats why your request didnt had a
body on the exemple you previously provided.

If you explained a little bit more of your app context, would be easier to
explain more.

I realise this is probably overkill for your needs; but django-suit allows 
for a ton of customisation options for the admin, one of which is the 
ability to supply "units" as part of the data entry forms - see:

Re: Sending Data from client side(another computer) to Django(my computer) using Socket library

[Jani Tiainen]

Hi,

Sounds like you're mixing up terms and technologies here and really you are 
trying something that Django was never designed for.

It would be really helpful to know what are you really trying to do, instead of 
just trying techniques that may or may not work for your case.

Re: Sending Data from client side(another computer) to Django(my computer) using Socket library

[Guilherme Leal]

Just to clarify, in your browser, if you simply "navigate" to the url of
your view, the browser will issue a GET to the server.

If you write the JavaScript function, you can specify the method of your
request... preaty much the same thing as you did in the exemple that you
sent.

Its fairly trivial, and JQuery makes it even simpler
.

 You can find here some directions on forming the request validly,

 as you apparently don't want to use any of the libraries below.

 Using one of the above-listed libraries would still accomplish what you
 are trying to do, as you described here,

 so I suspect that you are doing something more that we missed. Perhaps
 you could tell us why you want to do this?

[steve malise]

Meaning write JavaScript code to make a request?
how can achieve it other than writing JavaScript code?

Re: Sending Data from client side(another computer) to Django(my computer) using Socket library

[Guilherme Leal]

The "navigation" of your browser always performs a GET method. If you're
trying to test that kind of request in the browser, the best aproach would
be open the JavaScript and make the request there.

How to fix the UnboundLocalError

[田福顿]

*This is my code, *

def test_words(request):
if request.method == "POST":
i_d = request.user.id
pre_word = []
pre_mean = []
pre_ques = 
{"word":"","option1":"","option2":"","option3":"","option4":""}
key_list = ["option1","option2","option3","option4"]
pre_set =WordBase.objects.order_by('?')[:4]
for pre_ser_odd in pre_set:
pre_word.append(pre_ser_odd.word)
pre_mean.append(pre_ser_odd.mean)
pre_ques["word"] = random.choice(pre_word)
while option_key:
option_key = random.choice(key_list)
option_value = random.choice(pre_mean)
pre_ques[option_key] = option_value
key_list.remove(option_key)
pre_mean.remove(option_value)
context = RequestContext(request)
return 
render_to_response('tag_study/test_words.html',{"pre_ques":pre_ques}, 
context)

*I have no idea about the error, the tracebank is *
*UnboundLocalError at /tag_study/test_words/*

*local variable 'pre_ques' referenced before assignment*

rollback the update query

[Simran Singh]

I am really new to Django and I am using Django 1.8. Many of the 
manual_transaction features have been depreciated in this. I have used 
*@transaction.atomic(None, 
True)* to pack the transaction and rollback the updates if at any point the 
condition is not met. 
I tried to store the transaction in savepoint and used  *savepoint_rollback* 
or *savepoint_commit* as per the condition. But I am having no luck here. 
No matter where the control goes but as soon as atomic block ends, it is 
committing the changes in mysql db.  
Any kind of help or leads would be highly appreciated.

Django 1.7 - data migration which needs content types populated

[Santiago L]

Hi,

I'm migrating an app from Django 1.6 to 1.7 and I need to create a data 
migration to load some initial data.

Some of the migrations requires that Content Types are populated in order 
to create some objects with Generic Relations.
# models.py

class TincHost(models.Model):
name = models.CharField(max_length=32, unique=True)
content_type = models.ForeignKey(ContentType)
object_id = models.PositiveIntegerField()
content_object = generic.GenericForeignKey()


class Server(models.Model):
name = models.CharField(max_length=256, unique=True)
tinc = generic.GenericRelation(TincHost)


# migrations/0002_initial_data.py

def create_tinc_server(apps, schema_editor):
# ...
TincHost.objects.create(content_type=ctype, object_id=1, name='server')


class Migration(migrations.Migration):
dependencies = [ 
('contenttypes', '0001_initial'),
('myapp', '0001_initial'),
]   

operations = [ 
migrations.RunPython(create_tinc_server)
] 


This page[1] suggests adding this code to the migration:

from django.contrib.contenttypes.management import update_all_contenttypes
update_all_contenttypes()


It works, but there is a better or standar way to achieve that?

Re: Admin site in Django 1.8 tutorial giving CSRF errors

[aRkadeFR]

Can you provide us more information?
Your url / views + admin.py and the settings
at least?

Thanks

No I have not made any changes to the admin templates. I simply
followed the instructions in the tutorial. I am using Django's
runserver per the tutorial instructions. I am totally stumped.

Hey,

You shouldn't see these errors since the templates with the form
and so the CSRF token are generated from the contrib app admin.

Could you provide us more details of the error? Did you override
the admin templates?

Thanks,

Hi,

I am working through the Django 1.8 tutorial. I finished part one and
am starting on part 2. I created an admin user but when I login to the
/admin page I receive a 403 Error because CSRF verification failed.

Any idea what the problem is?

Thanks,
