Re: getting 500 131 error on page not found

[Sabine Maennel]

Dear Tom,  Thanks for your reply, but I did not have DEBUG=True on. With 
DEBUG=True the program behaves as expected. Things go wrong just when I set 
DEBUG=False. But thanks anyway for your reply.

Re: getting 500 131 error on page not found

[Sabine Maennel]

Dear Collin,

you hit the nail right right on top. That was it! I feel so thankful 
towards you! I would never have thought about the context processors. 

I am so thankful to everybody here in the Django User group to always 
taking the time and helping me out. I will try to give back, as soon as I 
get to be more experienced! 

I have the ADMINS setting in place in my production settings file, Collin. 
I was just trying to understand the error in my local environment first, 
since it occurred even there.

You have been helping me out quite a lot lately. Where are you located? How 
long have you been doing Django?
   Thanks again and with kind regards
 Sabine Maennel

ImportError cannot import name

[Juan Carlos]

Hi everyone,

When I execute the command:

python manage.py runserver &

The response is:

Traceback (most recent call last):

If I comment (#) the last line, the bug dissapears.  ¿What can I do?  I 
have Django 1.7 with Python 2.7.  Thanks for your attention.

ImportError failure

[Juan Carlos]

Hi everyone,

When I execute
python manage.py runserver

it appers:
ImportError: cannot import name 'example' from 'exsite'

The relative code in the settings.py file is:

What can I do?

My django version is 1.7, with Python 2.7.  I'm new in this interesting 
world of Django.  Thanks for your help, and time.

Working with Google Analytics API

[Muhammed Tüfekyapan]

Hi Everyone,



I want to make an app. User come on site, they signed in and give access to 
their google analytics account.

And I generate some reports for them.

I try to use Google Analytics API but I think I use the wrong one. 
https://developers.google.com/analytics/


Which one I should use? Is there any library for that?

Re: ImportError cannot import name

[Sabine Maennel]

Hello Juan, if your project is "exsite" and your app is "example" then you 
should probably just add "example" to the list of installed apps. Try it, 
hope it works.
with kind regards
Sabine

How can I make the field layout of a model form dynamic?

[DJ-Tom]

Hi,

I have a model that contains either a text or a numerical information, 
based on the type of the entry:

equipment = models.ForeignKey(equipment)
number = models.DecimalField('Amount/number', max_digits=6, 
decimal_places=2, blank=True, null=False, default=0)
text = models.TextField("Text", blank=True, null=True, default='')

Based on that model I created a model form:

class RoomsetupEquipmentForm(ModelForm):
equipment = 
forms.ModelChoiceField(queryset=equipment.activeobjects.order_by('category__name',
 
'name'))

def __init__(self, *args, **kwargs):
super(RoomsetupEquipmentForm, self).__init__(*args, **kwargs)
self.fields['equipment'].choices = equipment_as_choices()

class Meta:
model = roomsetup_equipments
fields = ('equipment', 'number', 'text')

I'm looking for a way to selectively show either the number or the text 
field when the form is created.

Thomas

Re: ImportError failure

[Serdar Dalgic]

Hi Juan,

I believe you might have a problem while importing "example". Can you
check the line you're importing example and where did you put this
"exsite.example" module?

Your directory structure should be like this:

mysite/
manage.py
mysite/
__init__.py
settings.py
urls.py
wsgi.py
exsite/
__init__.py
example.py
another_app/
__init__.py
   another_module.py

So that you can import exsite.example in your another_module.py like:

from exsite.example import AnyClassYouWantToImport

I hope this helps.

p.s. mind the "__init__.py"s on the modules you want to import. There
must be one in your "exsite" dir.
p.s.2. Instead of an example.py file under exsite dir, you may have
written it under __init__.py file as

mysite/
...
mysite/
__init__.py
...

in this __init__.py, you may have
class Example(object):
...
...

this is OK either ;)

How are you doing?
Have you looked into django oscar? Google it and take it from there. It is 
the best django ecommerce package.

django 1.7 migrations: changes detected while nothing has changed ?

[Michael]

Hi,

Does anybody know how are changes detected by the ```makemigrations``` 
command in django 1.7?
It seems that I have a bug. The original post is on stackoverflow 

 
but no one has replied so I am trying here.


I have the issue that it always tells me there are changes for one of my 
field whereas there are not. When I run the command, it just writes the 
same migration file over and over with no changes.

The field is a custom field on which I implemented the deconstruct method 
and have some parameters that are objects so I used the deconstructible 
decorator.

I created a project on github that replicates the issue: 
https://github.com/YAmikep/django-testmigrations

What did I do wrong? Is this a bug?


Here is what I ran:

/projects/testmigrations$ python manage.py makemigrations app1
Migrations for 'app1':
  0001_initial.py:
- Create model ModelA
/projects/testmigrations$ python manage.py migrate
Operations to perform:
  Apply all migrations: admin, contenttypes, auth, app1, sessions
Running migrations:
  Applying contenttypes.0001_initial... OK
  Applying auth.0001_initial... OK
  Applying admin.0001_initial... OK
  Applying app1.0001_initial... OK
  Applying sessions.0001_initial... OK
/projects/testmigrations$ python manage.py makemigrations
Migrations for 'app1':
  0002_auto_20141014_2123.py:
- Alter field field1 on modela
/projects/testmigrations$ python manage.py makemigrations
Migrations for 'app1':
  0003_auto_20141014_2123.py:
- Alter field field1 on modela


The migration files 0002_auto_20141014_2123.py and 
0003_auto_20141014_2123.py contain the exact same operations:

operations = [
migrations.AlterField(
model_name='modela',
name='field1',
field=app1.models.CustomField(max_length=50, 
value_manager=app1.models.ValueManager(values=[app1.models.Value(val=1), 
app1.models.Value(val=2)])),
),
]


Thanks
Mike

Installing django on red hat linux box

[robert brook]

I have alot of experience installing packages on windows and mac and it 
goes very smoothly.
I do not have alot of experience doing the installs on a Linux box.

I am running into problems installing 4 packages.

The Lan team tried yum, but the basic django packages were not available.

Then I tried installing pip and I got proxy errors using the get-pip.py 
script

So I fell back to installing the dowloaded packages with the old standy 
 setup.py install which fails.

I am attaching the top of the log

Anyone have any suggestions how to proceed?

Re: django 1.7 migrations: changes detected while nothing has changed ?

[Markus Holtermann]

Hey Michael,

The problem seems to be the same as in #23473 
https://code.djangoproject.com/ticket/23473 . Try adding a __eq__ method on the 
classes marked as deconstructible.

Use yum to install python and virtualenv and the rest should go easily using a 
virtualenv setup.

This is commonly recommended for the other platforms also.

Re: Installing django on red hat linux box

[Pat Claffey]

Hi,
I assume you have python installed successfully.  What version?  If you 
install python 3.4 then pip should install automatically (unless  3.4. is a 
second python install in which case pip does not install)

You should be able to see the python (and pip) executables in /usr/bin or 
/usr/local/bin.  For example on my system I see python2.6 and pip installed 
on /usr/bin (python is just a link to python2.6).  I manually installed 
python3.4 and pip3.4.  I see these executables in /usr/local/bin.

python2.6 was pre-installed on my linux box (red hat).  I installed 
python3.4 and pip3.4 manually.

Re: Installing django on red hat linux box

[robert brook]

I have installed a virtualenv on my local machine to do the development.

On the development web server using a virutal environment is not really 
important.

The packages that I am interested in are not available through yum.

Trying to install the packages locally displays header errors.

Any suggestions around this?

Re: Installing django on red hat linux box

[Pat Claffey]

once I got pip sorted out it was really easy install django (just pip 
install django)  - so advise is to get pip working.  You will need it for 
other python packages also.

Re: Installing django on red hat linux box

[robert brook]

I have python 3.3.

Had to coerce red hat to do allow the install  3.3.  Must have been  a 
stripped down version.
version 6 came with python 2.6 installed.

Must be a stripped down version as pip does not come with python 3.3

I believe I need the package , python3.3-dev, to get the headers to utilize 
the std   setup.py install

I am going to follow up with Red Hat.

Thanks

Re: Installing django on red hat linux box

[robert brook]

I am a contractor in a large organziation.  They must have everything 
locked down.

I downloaded get-pip.py and got errors that seemed to be proxy, firewall 
security issues, that is why I fell back to implementing through setup.py
and ran into the header issues.

Thanks

problem with TransactionTestCase and sqlite

[Tim Court]

Hi,

I'm having a problem using a TransactionTestCase with a sqlite database and 
was hoping someone could tell me where I've gone wrong.

I'm porting a project from Django 1.6 to 1.7 that uses LiveServerTestCase 
with a sqlite test database. I converted all of my initial_data fixtures to 
be proper data migrations. When I did that my live server tests started 
failing until I stumbled upon the serialized_rollback option to 
TransactionTestCase. However now I get the following error instead:

IntegrityError: columns app_label, model are not unique


I did some digging and it looks like the django.contrib.contenttypes app 
has a post-migrate script that populates the content type table. However, 
using the serialized_rollback option to refresh my migrated data also 
inserts saved duplicates into the content type table, which results in this 
exception.

I've created a minimal project that demonstrates the problem here: 
https://github.com/tctimmeh/djangomigrate

Is there any way to get my tests working? Any advice would be appreciated.

Thanks!

Re: Installing django on red hat linux box

[Pat Claffey]

One final suggestion...

If you are using python3.3 then pip may be called pip3.3

You could try "which python3.3"  or  "which python" (if python points to 
python3.3).  This should give you path to python executable directory.  If 
you look there you may be lucky
and see a pip executable - perhaps pip3.3

Regards,
pat

django-admin creates the views.py files in the wrong place!

[Aliane Abdelouahab]

Hi,
Django 1.7 when a beginner runs the first tutorial, he has to change the 
views.py file outside the app to the whole project itself.
i found 
this, 
http://stackoverflow.com/questions/22011791/importerror-no-module-named-views 
and it seems it is related to Django 1.6 too?

How do I display list of pages with a ListView object?

[Daniel Grace]

Hi,
How do I display list of pages with a ListView object?  For example display 
a link for each page (except maybe the current page):
previous 1 2 3 4 next

Currently I use the following in a view to display "previous" and "next":
{% if page_obj.has_previous %}
previous
{% endif %}
Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}.
{% if page_obj.has_next %}
next
{% endif %}

I tried using a for loop with a template tag and a reference to page_obj, 
but I could not get it to work.  Any ideas?

Thanks

Re: How do I display list of pages with a ListView object?

[Daniel Grace]

I found a solution by writing a custom template tag, passing in the current 
page and number of pages from page_obj.
Is that an acceptable solution or can this be done without a custom tag?

Re: How can I make the field layout of a model form dynamic?

[Bill Freeman]

Perhaps the most djangoish way would be to create two model forms, with
different fields excluded, and choose which to render in the template.

Or you could render CSS style information to hide one or the other.

Or you could use JavaScript to hide one or the other based on something
else that you render.

Or write the template code to render the fields instead of using .as_p, etc.

Is there a way to supress blank lines in the HTML?

[Daniel Grace]

Hi,
Is there a way to suppress blank lines in the HTML?
I tried using the spaceless tag but it is overkill for what I want.
I just want to suppress the blank lines from the HTML and not all space.

Any ideas?

Thanks

Re: Import error in settings.py

[Felix Unchained]

Just thought you might get a kick out of the fact that I just found this 
very useful – 4 years later. Thanks.

Re: Installing django on red hat linux box

[Kelvin Wong]

Take a look at the Software Collections (ver 1.1 works on RHEL 7)

http://developerblog.redhat.com/2013/01/28/software-collections-on-red-hat-enterprise-linux/


$ sudo yum install python33-python-devel
$ scl enable python33 bash

You can then install everything locally in your application user's home 
directory.

This snip is from a virtualenv build script. I use virtualenvs on my 
deployments.

$ curl https://bootstrap.pypa.io/get-pip.py | python3.3 - --user
$ echo 'export PATH=$HOME/.local/bin:$PATH' >> $HOME/.bash_profile
$ source ~/.bash_profile
$ which pip
/home/youruser/.local/bin/pip

$ pip install --user virtualenv virtualenvwrapper
$ echo 'source $HOME/.local/bin/virtualenvwrapper.sh' >> $HOME/.bash_profile
$ source ~/.bash_profile

Django REST Framework

[Max Nathaniel Ho]

Hi all,

I just came across Django REST Framework. From what I have read up so far, 
its a Web API framework.

What does it do and what is the difference between this and the regular 
Django Web Framework?

Thanks!

Re: Django REST Framework

[Russell Keith-Magee]

Hi Max,

Django ReST Framework, as the name suggests, is a framework for building
ReST APIs in Django.

It's not officially part of the Django framework, but it's creator and
principle maintainer - Tom Christie - is a member of the Django core team.
Tom recently held a Kickstarter to fund v3 of the framework; that
Kickstarter was extraordinarily successful due to the support of the
community.

If you need to write a ReSTful API for your Django app, it's well worth
your time to take a look at it.

Yours,
Russ Magee %-)

Re: ImportError cannot import name

[Sabine Maennel]

Hello Juan,

I think your settings file should look like this:
In *settings.py* I have:

INSTALLED_APPS = (
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'example',
)

but to be sure I would need to see you directory structure. Hope this 
helps. 
with kind regards
 Sabine
