Yes, you can develop a website were some data is processed and presented in
the template by the backend, and some is fetched using AJAX
(Javascript/Angular) from the frontend.

I do not know a specific tutorial to point you, but from a quick search,
this one seems to cover a lot of things:

I have more questions..

Is there a way to develop a web site by combining MPA and SPA ? 

And..

Can you please recommend a tutorial of django+angularjs that is about 
configuration, building structure, and etc for dividing backend and 
frontend ?

Re: How should I develop a web site and mobile apps(iOS/Android) as Facebook(using DRF + Angularjs)?

1) The Facebook WEBSITE is a MPA, but some of it's content is loaded via
ajax (like the newsfeed). The Facebook mobile app is a native application.
The Android one is developed in Java, and the iOS is developed in Objectve-C

2) If you use a cross-paltform framework like Cordova you will be
programming in HTML/CSS and Javascript. The framework will handle the
generation of the apps for each platform from your javascript code.
HTML/CSS will define how the app looks and Javascript will handle fetching
data from the server and presenting it on the app. AngularJS is a
Javascript framework that give you some nice tools, but you are free to
chose between using it or not.

3) There's no such a thing as "the best cross-platform to fit DRF". The
backend (Django/DRF) will handle storing and processing data, and the
mobile app will fetch data from the backend and show it to the user. The
platform you will use and the backend are separated things and do not
interfere within each other.
About using native or cross-platform, I expressed MY OPNION in the second
email of the last message:
https://groups.google.com/forum/#!topic/django-users/B8v9wjR4-M0
But this is a polemic subject, other people may have different opinions
about it.

Re: How should I develop a web site and mobile apps(iOS/Android) as Facebook(using DRF + Angularjs)?

Hi,

I think I partially answered this to you in your previous question:
https://groups.google.com/forum/#!topic/django-users/B8v9wjR4-M0
Can you tell me if you didn't understand something?

Mobile and AngularJS apps don't work exactly the same as a normal web page.
While in a normal web page, the frontend (what the user sees) is processed
in the backend (django) and sent to the user, in a Mobile or AngularJS app,
the frontend is already in the user device and it only fetches the data to
fill in the frontend.
The default Django behaviour is to work with "normal web pages", but when
you use Django REST Framework it makes it easy to develop APIs and return
JSON data (JSON is one of the most popular data formats).

Now, normal iOS apps are build in Objective-C, normal Android apps are
developed in Java. But it's possible to built both iOS and Android apps
using Javascript, some of the frameworks that do this are:
Cordova/Phonegap, Titanium and Ionic (witch is AngularJS compatible).

There are lots of tutorials in the interned for all this technologies.
This is pretty much the basics of how this works. Feel free to ask more
specific questions if you need more detailed response.

I can help with this one. In fact you cant combine annotations with
filters. See

https://docs.djangoproject.com/en/1.8/topics/db/aggregation/#aggregations-and-other-queryset-clauses

"...When used with an annotate() clause, a filter has the effect of
constraining the objects for which an annotation is calculated. For
example..."

e.g.::


Store.objects.filter(books__pubdate__year=2014).annotate(min_2014_price=Min('books__price'),
max_2014_price=Max('books__price'))

Re: form detail view using generic view

Hi Pradeep,

when data is saved, you want to show it in the form or as "view-only"?
If it is a form you need, Use a CreateView, and the redirect it to a
UpdateView. Otherwise, do a CreateView and redirect to a TemplateView.

CreateView ->
https://docs.djangoproject.com/en/1.8/ref/class-based-views/generic-editing/#django.views.generic.edit.CreateView
UpdateView ->
https://docs.djangoproject.com/en/1.8/ref/class-based-views/generic-editing/#django.views.generic.edit.UpdateView
TemplateView ->

Re: Graceful Reloading for Schema Changes - UWSGI - Gunicorn?

I'm not familiar with uWSGI. On gunicorn you send it SIGHUP (kill -HUP

Graceful Reloading for Schema Changes - UWSGI - Gunicorn?

2015-04-16 Thread Shapath Neupane

 

Hello Djangonats,

How do you reload Django script changes with UWSGI? I know `touch-reload 
` 
exists with UWSGI however I was looking more into what uwsgi does when the 
schema(s) in the models change? How do you handle database changes without 
affecting or rebooting the server? Rebooting UWSGI does not sound like a 
good idea.

A Load Balancer (HAProxy) ?

*More Questions*

Does something like that exist in Gunicorn?

Regards,

Shapath.

Django Custom lookup running different SQL query than it's displaying in str(query)

2015-04-16 Thread d33tah

(This is basically a copy of http://stackoverflow.com/q/29680060/1091116 - 
I hope that this is allowed here)

Consider the following `urls.py` - for brevity, I decided to put the 
example in one file:

from django.conf.urls import patterns, include, url

from django.http import HttpResponse
from django.db import models

def x(request):
class A(models.Model):
title = models.CharField(max_length=1024)
class RightAnchored(models.Lookup):
lookup_name = 'rightanchored'

def as_sql(self, compiler, connection):
lhs, lhs_params = self.process_lhs(compiler, connection)
rhs, rhs_params = self.process_rhs(compiler, connection)
params = lhs_params + rhs_params
return "REVERSE(%s) LIKE REVERSE(%s)" % (lhs, rhs), params

models.CharField.register_lookup(RightAnchored)
q = A.objects.filter(title__rightanchored='%b')
return HttpResponse(str(q.query))

urlpatterns = patterns('',
url(r'^$', x),
)

For some reason, visiting http://localhost:8000 gives me: `SELECT 
"w_a"."id", "w_a"."title" FROM "w_a" WHERE REVERSE("w_a"."title") LIKE 
REVERSE(%b)`, while running the command would result in `SELECT "w_a"."id", 
"w_a"."title" FROM "w_a" WHERE REVERSE("w_a"."title") LIKE REVERSE('%b')` 
(note the extra `''` inside `LIKE REVERSE`). This means that the displayed 
query is different  than one that is being run. How can I make my Lookup 
behave properly when `str(q.query)` is called?

Queryset/order_by option sort keys string manipulation

2015-04-16 Thread Henry Versemann

I have a string of sort keys which I've generated dynamically using the
name of the table (model) that I'm trying to retrieve elements from, while
putting them in a pre-determined sort order. The original sort key string
looks like this:

domain_code,request_url,request_description,id,request_method,response_type

Then I do some string manipulation of the "sort_keys" string object to
produce this second version of the string:

'domain_code','request_url','request_description','id','request_method','response_type'

to be used for the "sort_keys" of the Queryset "order_by" option.

I'm coding the Queryset with the "order_by" option like this:

tblEntryLst = table_class.objects.order_by(sort_keys)

which fails with a django.core.exceptions.FieldError.
But if I code it the exact same way and hard-code the "sort_keys" like this:

tblEntryLst =
table_class.objects.order_by('domain_code','request_url','request_description','id','request_method','response_type')

Then everything works.

I'm thinking the reason it fails in the first instance is because the
sort_keys object is maybe being evaluated before the Queryset command is
actually run and so at that point the "sort_keys" are no longer in the
proper comma-separated string object format to work within the confines of
the command.

And in the second case the Queryset command does work because the sort-keys
aren't evaluated before the command is actually run.

I hope this makes sense, and would appreciate any help in getting this to
work without having to resort to hard-coding my sort keys, instead of using
the dynamic ones.

Thanks for the help.

Henry

Re: Django Userena 'OrderedDict' object has no attribute 'keyOrder'

Hi Vijay,

Looks like Django does not use SortedDict anymore
(https://github.com/django/django/commit/07876cf02b6db453ca0397c29c225668872fa96d#django/forms/forms.py)
The self.fields.keyOrder does not work anymore, django-userena has an
obsolete documentation.
Try to remove def __init__(self, *args, **kw): from your class,
ordering should be based on fields definition order.

Best regards,
Pavel

Transform all Django exceptions to JSON?

2015-04-16 Thread jack

Hello, 

I use django rest framework to make API server. DRF catches some Django 
exceptions and transforms them in JSON. However some exceptions, like 404, 
are still returned as Django pages (at least it works that way on my 
machine). How can I wrap all exceptions in JSON from any library? I'm 
working on mobile app and I can't debug html dumps from Django in console 
:( 

Am I missing something important?

Re: Django keep variable in memory, even if i refresh the page

2015-04-16 Thread Silvio Benvegnù

But I need to do it:

**ok I try to explain better my situation**:

- I've got a class that is a "javascript repository". Its role is to 
respond with a string of javascript functions.  
Javascript functions are organized in indipendent modules (list of 
functions), so I can attach to my page just needed functions.  
Different modules can share same functions.
- In my view I specify the url of a function (it is in the same view), 
get_js_code, whose rule is to return javascript code (with: `return 
HttpResponse(code,content_type="application/x-javascript")` )
- get_js_code initiate that "javascript repository class", asking one or 
more modules (list of functions), and my class returns functions just one 
time, even if a function belongs to more than one module.  
- in my template I specify get_js_code url as a javascript resource, and 
javascript code is downloaded with the page from Django

It works well _BUT_:

- a module is needed from every app, so I specify in a Middleware an url 
that brings to another app/function that initiate that class in order to 
attach as javascript resource the common javascript module.

**Here is the problem**:

- my "javascript repository class" has a list that contains returned 
javascript functions list in order to return a function just one time. It 
works well but just one time: infact if I reload the page the list does not 
expire and no javascript funtions are returned.

Very hard to explain, I hope its clear now.

PS: I was wrong, I don't initiate the class inside a Middleware.

PPS: I know that is unusual to put javascript code inside Python code, but 
I'm testing this solution.

you are instantiating the variable on class definition, try doing on
function execution instead

Checking for foreign key in clean method - Django 1.77 vs 1.8

2015-04-16 Thread Graham Oliver

Hi guys 
I have some code in a clean() method that works ok on Django 1.77 but stops 
working in 1.8 

The scenario 

class Span(models.Model): 

happening = models.ForeignKey('Happening', blank = True, null = True) 
soul_class = models.ForeignKey('SoulClass', blank = True, null = True) 


In the clean() method of the Span class I have a check as follows 
if self.happening: 
foo 

if self.soul_class: 
bar 

This was working fine in Django up to 1.77 but when I upgrade to Django 1.8 
both self.happening **and** self.soul_class are None. 

The primary difference appears to be the value of _soul_class_cache as 
follows. 

The Span object in 1.77 looks like 
{'end_date': None, 'id': None, '_state': , 'start_date': datetime.date(2015, 4, 16), 
'soul_class_id': None, 'end_time': datetime.time(14, 12), 'happening_id': 
None, '_happening_cache': None, 'start_time': datetime.time(14, 12), 
'_soul_class_cache': } 

In 1.8 
{'start_time': datetime.time(14, 0), 'end_date': None, 'soul_class_id': 
None, '_state': , 'happening_id': None, '_happening_cache': None, 
'_soul_class_cache': None, 'end_time': datetime.time(15, 0), 'id': None, 
'start_date': datetime.date(2015, 4, 16)} 

Any ideas? 
Cheers 
g

Django keep variable in memory, even if i refresh the page

2015-04-16 Thread Silvio Benvegnù



I'm using Django Framework 1.7 with its webserver.

I have a custom class where I declare a static variable, a list, where I 
append some values:

class my_class:

list = [] 

def __init__( self, *args, **kwargs ): 
[...]

def append_value(self,value):
self.list.append( value )

I use a static variable because I call this function different times. 
During a single page load my class works well but I noticed that 
my_class.list never expire.

To reset the list I have to restart the webserver.

I come from PHP and Perl where every time you refresh a page all yor 
variables are cleared if you don't save them in some way.

I use session, sure, but I don't save that list into session, at least not 
voluntarily.

NOTE: I don't know, during script execution, the first or the last time I 
call my_class().

How can I reset the list every time I reload/change page?
