Re: Installation Advice - Win/PostgreSQL/Django

2016-06-02 Thread Avraham Serour

For development you only really need django, you can develop with sqlite
and deploy on a server using postgres, using postgres on the development
machine is nice but not strictly necessary.
If this is for a production machine you will also need a webserver

Re: Test fails when run in whole test suite - but not stand-alone?

2016-06-02 Thread Adam Stein

When I've had that happen before, it's because some previous test
changed something (like a setting value or the site domain) that
influenced the test that failed. To narrow it down, I would run all the
tests up to and including the failed one. That should fail, then I
start taking out half the tests before. If the test still fails, I keep
cutting in half until I can determine which previous test is causing
issues. If, after cutting out tests, the problem test passes, then I
need to put back in what I took out since it was one of those.
Once I figure out which previous test it was, I can start removing the
individual tests to finally get to the code causing the problem.
Usually, it's a case that a test changed something and I just have to
add in the teardown function to restore the state of whatever was
changed.

Installation Advice - Win/PostgreSQL/Django

2016-06-02 Thread cbt

Hi, folks,

I have found a lot of Django installation checklists out there. Most are
for very old versions. Others are rather vague, since they cover so many
options. Still others assume that everything is hosted somewhere else. I
have not yet been able to get the whole stack working in a local
environment.

Here's what I have done so far for my Windows development machine. If any
of you could advise on how to get to the next steps, I would really
appreciate it.

- Working, stable installation of Windows 7 (x64)
- Installed PostgreSQL 9.5.2
- Created a schema
- Created some tables
- Imported some data
- So far so good
- Installed Python 3.5.0
- (Started with 3.6 but had to downgrade repeatedly to find a version
compatible with psycopg2)
- Win 64
- C:\> python -- version returns 3.5.0
- Again, so far so good
- Installed psycopg2
- Version 2.6.1
- Win 64 (psycopg2-2.6.1.win-amd64-py3.5.exe)
- Seems to be installed correctly
- This is the latest version. (It seems to be a beta-test release.
It's a little hard to tell. However, it supports Python 3.5.)
- Django 1.9.6
- Downloaded and unzipped
- Didn't get any errors
- >>> import django
- No joy.
- PIP
- Whatever comes built into Python
- Not entirely sure what version
- Command line responds
- Not sure what to do with it

Are there more layers to install? Do you see any obvious version issues?
One thing I noticed is that my Windows PATH environment variable is very
long. If any of these modules are appending to it, that may not be working.
I could try weeding stuff out of my PATH, but that seems like a long shot.

Thanks a million!

Test fails when run in whole test suite - but not stand-alone?

2016-06-02 Thread Derek

I have a test that is failing when the file it is in is run as part of all
the other test files by the test runner.

If I just run only the file that contains this test -  then it passes.

(pass/fail refers to the very last assert in the code below.)

I'd appreciate any ideas or insights from anyone who can spot an obvious
mistake - or suggest some options to explore.

Thanks
Derek

Re: Django Suit admin panel - Static files configuration Django 1.6 not working

2016-06-02 Thread Roger Lanoue jr

I am rebuilding a new server from scratch now. 

New IP: Same setup with new IP from Digital Ocean 1click install - 

http://162.243.58.204/

I am going to try and setup the Static files directory again. 

Since they are using Django 1.6 and the command makemigration and migrate 
are not in 1.6
Should i start using Django 1.8 or 1.9 before configuring the server?

Did you use the login_required decorator on your view? Authentication is
something you have to specify you want for a page, it is not assumed.

Add date2016 to your context:

Then it's just {{ date2016 }} in your template.

Re: Hi - I'm new to Python and DJango

2016-06-02 Thread Luis Zárate

Sure,

It's good enough and more.

There is some development in ERP but nothing stable or usable (not that I
known).

So if you are interested in develop something could be great know about.

Note: I thing first step is search what programs exists and try to
collaborate with one, but if nothing is good enough then start with new
develop and look for help.

Re: Views.py & template (queryset)

2016-06-02 Thread Franck

Hello Stephen,
Thanks for your help, ok I think it's better to used views for what I need 
to do.
Last question, how I can define this in view and template ?
For the moment I used 'for' & 'endfor' in my template to show all my items, 
but I want to show "date2016" in only one field.

*Views.py*
from .models import Test
from datetime import datetime
from django.shortcuts import render, get_object_or_404

def test(request):
test = Test.objects.order_by('name')
*date2016 = Test.objects.filter(dateregister__contains='2016').count()* 
   ??
return render(request, 'test/test.html', {'test': test})


*Template:*








*{% for test in test %}{{ test.name }}{{ test.dateregister

Django suit and Static files not working in Django 1.6

2016-06-02 Thread Roger Lanoue jr

Hello All.

I learning my first Django experience and I am making some headway. I am 
stuck on my test server and Django suit admin. 

I my goal is to get the new admin from Django suit to work.

*Server setup*
Ubuntu 14.04 ( A Digital Ocean VPS with one click install ) 
Django Version 1.6
Python: 2.7
Nginx
Postgres

*Test server *
http://162.243.201.237/

*Admin (with django suit installed ) *
http://django-suit.readthedocs.io/en/develop/
http://162.243.201.237/admin/

User: Demo
password: Demo

The css is being applied to the djando suit .

*Ran command:*
python manage.py collectstatic

Results: 0 static files copied, 116 unmodified.


*My setting.py basics*

DEBUG = False 

TEMPLATE_DEBUG = False

STATIC_URL = '/static/'

STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static"),
'/home/django/django_project/static/',

When I look in to the static directory. nothing had been copied. 

Thank your for taking time to look at this and also sharing with me any 
clues on how to fix this.

Roger

Django Suit admin panel - Static files configuration Django 1.6 not working

2016-06-02 Thread Roger Lanoue jr

Hi Django users group.

I am test and learning django out. I have a testing server and got my test 
page up. 

Started to play with the Django suit control panel and ran in to some 
problems with my setup.

*Server: Digital Ocean one click install.*
Ubuntu 14.04
Nginx
Postgres
python 2.7
django 1.6

*Test server*
http://162.243.201.237/

*Admin panel: *http://django-suit.readthedocs.io/en/develop/
http://162.243.201.237/admin/
user: demo
pasword: demo

*Static file command I ran*
python manage.py collectstatic

results: 0 static files copied, 116 unmodified.

*Setting.py: Basics *
DEBUG = False 

TEMPLATE_DEBUG = False

ALLOWED_HOSTS = ['*']

STATIC_URL = '/static/'

STATICFILES_DIRS = [
os.path.join(BASE_DIR, "static"),
'/home/django/django_project/static/',

*Nginx setting:*

 # Your Django project's media files - amend as required
location /media  {
alias /home/django/django_project/django_project/media;
}

# your Django project's static files - amend as required
location /static {
alias /home/django/django_project/django_project/static; 
}

# Proxy the static assests for the Django Admin panel
location /static/admin {
   alias 
/usr/lib/python2.7/dist-packages/django/contrib/admin/static/admin/;
}

location / {
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header Host $http_host;
proxy_redirect off;
proxy_pass http://app_server;
}

 My goal is to get the Django suit working. I do not see anything in my 
static files directory for the admin suit so the css can be applied. 
I am missing something very simple to get this working.

Thank you for taking time to look at this and wish to get some clues.

Perhaps you could override the widget to a Textarea with the right
maxlength attribute? That should be fine if you don't target IE<10...


I'm guessing I have to first inherit the admin form for the page 
involved then tweak the widget.


Haven't played there before. Back to the docs ...

Thank you Michal

Re: Django 1.9 - Create an app that use the models from another app and dynamic CBV

2016-06-02 Thread sevenrrainbow

Thanks you James, 

To make it more clear.  Let's say I have companies(entities) and 
products(sub-entities) to be more clear. Regarding  the urls I use the main 
urls.py to include the urls.py from each app.

urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^companies/', include('company.urls', namespace='company'))

 In the entity app the urls.py :

urlpatterns = [
url(r'^$', CompanyListView.as_view(), name='list'),
url(r'^add/$', EntityCreateView.as_view(), name='create'),



*Normal View*

/companies/  - listing all
/companies/company-name/ - details about a company
/companies/products/ - listing all products of a company
/products/ - listing all products
/products/product/  - details about a product

*Editor*

/account/   - dashboard)
/account/add   - adding a company, the company is actually the account, no 
other info for account, and is onetoone relationship with user
/account/edit -update company data
/account/company-name/products/add - add a product to company
/account/company-name/product-name/edit - update product info 

The account app I try to use is to control the account, even if doesn't 
exist a model. I understand that I can use multiple urls patterns in 
urls.py for an app in general, *but can you gave me an example for the case 
above ? *(having just two apps companies and products)

 At the view level 

In the Dashboard(account) first I verify if the company exist and 
activated(approved by admin(boolean field). 

If the company doesn't exist(first time) show the CreateView(CBV) form, if 
exists and activated show the company info and others and if it is not 
activated show a Pending message.

Based on the solutions you presented, I think is having a generic view 
(empty with only logic or with one of the cases(pending,exist and active)) 
and to redirect to different urls and corresponding views.  

Or you think there is a better approach ?

You'll probably need to implement a permission system to control access to
resources.

One app can handle multiple URL schemes, both for anonymous and
authenticated requests simultaneously. You really only need multiple apps
when there is a clear separation of duties/functionality. They're really
more for organization of the code than any functional/technical reason.

You can have as many views as you'd like for the same model. It is common
in situations where an object can be in different states at different
times. For example, an account is created for a user, so the user needs to
claim it, and then the new user needs to modify their own account with the
right details and change passwords, etc. That may also include having
multiple forms for the same object as well.

Well, yes, and no. I wouldn't rely solely on the template to handle this
behavior. You'll be twisting yourself into a pretzel to make it work.
There's a couple of ways to make this work:

   - Have a single view that initially examines the situation, and then
   calls the respective functions or CBV's that handle the specific situation.
   Keeps the request logic within the view infrastructure, but not a typical
   strategy as far as I know. The same URL can then serve all of the
   situations.
   - Have a single view that builds a basic page structure, and use a JS
   framework and AJAX calls to build an SPA that displays the right
   information.
   - Have a separate view for each situation, along with a separate URL,
   and another view/URL for the main dashboard. Have the main dashboard view
   check for your logic, and redirect the browser to the URL for each action.
   Once the situation is corrected (form submitted, etc.) then redirect back
   to the main dashboard. This would be my preferred method.

You can use template inheritance in all of these situations to keep the
amount of template code down (which is generally advised since the template
system tends to be the slowest part of Django).

In most cases, you can't (and don't want to) use a queryset directly in the
template. That type of logic usually ends up in the view. The view is
responsible for preparing the data, whereas the template is responsible for
formatting the data provided by the view.

The reason that {{ test.count }} works is because you are storing a
queryset in the context, rather than the actual object (or list of objects
in this case). There are perfectly valid use cases for doing so, but keep
in mind there is a difference between a queryset and an actual object or
list of objects. If you use a queryset, you'll incur a database hit every
time you refer to that variable in the template, which is likely not what
you want. A notable exception is when looping over the queryset.

I'd recommend reading up on the template language and becoming familiar
with the (deliberate) restrictions on the template language:
https://docs.djangoproject.com/en/1.9/ref/templates/language/#variables

Yep, that was the whole intention of using the abstract classes. Glad it
