How to use Python proxy server when getting [Errno 111] Connection refuse
I try to test Odoo Web Service API from Python and everything works fine from localhost using a basic Django app and xmlrpclib. But when I host it at pythonanywhere I get a [Errno 111] Connection refused error. On their help page they describe that ports are closed on free accounts and that their HTTP proxy at proxy.server:3128 has to be used. How to do that? Here is the Django code of my view (yes I know that's bad practice to put html in the view, just for testing): from django.http import HttpResponse import xmlrpclib url = "https://demo3.odoo.com" db = "demo_100_1489044950" username = "admin" password = "admin" #odoo service connection common = xmlrpclib.ServerProxy('{}/xmlrpc/2/common'.format(url)) uid = common.authenticate(db, username, password, {}) models = xmlrpclib.ServerProxy('{}/xmlrpc/2/object'.format(url)) products = models.execute_kw(db, uid, password, 'product.template', 'search_read', [[]], {'fields': ['name', 'list_price'], 'limit': 10}) for product in products: print product['id'], product['name'], product['list_price'] def index(request): html = "<html><body><h1>Odoo Products</h1>" for product in products: name = product['name'].encode("utf-8", "strict") html += "<div>"+name+": "+str(product['list_price'])+"</div>" html += "</body></html>" return HttpResponse(html) ps: Source code of Django app is in this github repository -
Django "trans" template tag using wrong language
I have a site using Django 1.10 with German and English as available languages, where German is the source language. Dynamic content is translated with django-modeltranslation and for static strings I am using Django's built-in trans template tag. I want Django to return the page in the visitor's preferred language. I have read how Django discovers language preference carefully several times, and I think I have everything right. As I change my language settings in my browser, the value of the LANGUAGE_CODE variable when displayed in a template always changes accordingly, and also the dynamic content is always returned in the expected language by django-modeltranslation. Also the admin interface and extensions like rosetta and django-debug-toolbar switch their interface language nicely as expected. It's only the trans template tag that is not picking my browser's language preference. Instead, it seems to directly resort to the initial value of the LANGUAGE_CODE variable as it is originally set in the settings file, without going through the algorithm described in the aforementioned link. The locale middleware is of course in place, and so are the *.po and *.mo files as well. The browser request headers also look fine. Because everything except the trans tag … -
Django builtin test client can't find static files provided by jdango-bower?
Django succeeded to find static files provided by django-bower when using python manage runserver, but inside a TestCase, django failed to find those staticfiles: from django.test import TestCase from django.urls import reverse class ExampleTestCase(TestCase): def test_client(self): self.client.post(reverse('test')) The above code will generate exception like this: ValueError: The file 'bootstrap/dist/css/bootstrap.css' could not be found with <django.contrib.staticfiles.storage.ManifestStaticFilesStorage object at 0x7fe30824fb10>. Do i need to do some extra configurations for django-bower to work inside django unittest? -
Django - add text beetween modelform fields

Something like: You can add site to 2 categories You can add site to 2 subcategories Just normal html text. How can I achieve that? -

Translating text in external js file in Django

Correct Way for Celery Process Architecture and demonizing
I have a Python/Django Project running on uwsgi/nginx. For asynchronous task we are using rabbitmq/celeryd and supervisord to manage all the daemons Versions: python: 2.7 django: 1.9.7 celery: 3.1.23 django-celery: 3.1.17 Celery has 10 queue of type Direct (say queue1, queue2, ...) Each queue is handled by a separate celeryd process which is manage via supervisord. each supervisord process looks as following [program:app_queue_worker] command=/var/www/myproj/venv/bin/celery worker -A myproj -c 2 --queue=queue1 --loglevel=INFO directory=/var/www/myproj/ user=ubuntu numprocs=1 autostart=true autorestart=true startsecs=10 exitcodes=1 stopwaitsecs = 600 killasgroup=true priority=1000 Hence Supervisord is running 10 Mainprocess and 20 Worker process Other Thing I have noticed is uwsgi also spawns some celery workers(Dont understand how and why, YET ) with concurrency=2. So if I have 4 uwsgi process running i will have an addition 10 celery workers running All these workers are each taking 200-300M memory? Something is wrong here I feel it but I am not able to put my finger on it. Celery shouldn't be running such memory heavy process? Note: Debug=False, there is no memory leakage due to debug Can someone please comment on the architecture if it is correct or wrong? Would it be better to run 2-3 celery MainProcesses which listen all queues … -

Reactjs and Django Independent Functionality
I am new to django and reactjs and I want to ask if it is possible to make an application that have the following requirements: "Reactjs only care of front-end". No need to import the scripts of reactjs to the templates of Django. Most of the tutorial I read are importing the bundles of Reactjs into the Django templates. "Django handles everything on backend". Django only wait for any request and return response. If you know any blog, tutorials please include it on your answers. Thank you very much! -

Django and wordpress simultanous logout
I have this project in which user simultaneously login into Django as well as Wordpress accounts. To achieve Simultanous logout, I used Javascript to delete the authentication cookie of Wordpress and thus automatically logging out the user. This works fine as long as user clicks on "logout" button. On clicking logout a Javascript function is called and wordpress cookie is deleted and thus making user logged out of Wordpress and user is logged out of Django by using normal Django functionality. Now the problem occurs when user directly type the logout url "localhost:8000/logout" in address bar, this directly send request to Django server and without involving any JavaScript to delete the Wordpress cookie. How to achieve Wordpress logout in this situation when user directly types the logout url of Django? Note:- Wordpress and Django server are running on same host with different port. -

Can this be achieved through Aggregation?
I have achieved what I want but I'm not convinced it is the best approach. This is my model: class foo(models.Model): user = models.ForeignKey(User) rate = models.PositiveSmallIntegerField(default = 3) rate1 = models.PositiveSmallIntegerField(default = 3) rate2 = models.PositiveSmallIntegerField(default = 3) This is my view: sum = {} bad_rating = None rate = foo.objects.values('user').distinct().annotate(r=Avg("rate"), r1 = Avg("rate1"), r2= Avg("rate2")) for r in rate: sum[r['user']]=r['r']+r['r1']+r['r2'] bad_rating = sorted(sum.items(), key=operator.itemgetter(1)) Basically, I'm getting average of rate, rate1 and rate2 grouped by distinct users. Once I have gained the average of these three fields associated with distinct users, I want to add them all together, and keep the user association. In my case, I have a queryset at the beginning, then I store it in a dictionary, then I store it in a tupple list (because it allows me to order it and gain the lowest rating, or highest rating). Is it possible to achieve the same results through Django Queryset and aggregation? In example: My Queryset result: <QuerySet [{'r': 1.0, 'r2': 3.0, 'user': 16, 'r3': 5.0}, {'r': 4.333333333333333, 'r2': 2.1666666666666665, 'user': 17, 'r3': 5.0}, {'r': 2.0, 'r1': 2.0, 'user': 18, 'r2': 2.0}]> Instead I would like a queryset that would produce the following results: … -
Django get results from multiple rows into a list?

Is it possible for an attribute to receive two different type values in a Django model?
I need to create an evaluation model for a candidate for a job. The form should be a page that displays the criteria (which are another template, so here I would use the ForeignKey) and next to a field to give a note to this criterion, assign a note to this criterion ... so I thought if you have As an attribute receive two value, a ForeignKey and an integer, or some way to connect two different attributes of the same model into another variable, the foreignKey criterion and the note that was received ... I thought of a variable that receives two different values From the point of view of forms (for when I pass it to the template), I'm a beginner in Django and I do not know how I can solve this. Qaulquer hint and help are welcome! Grateful
