pytest & django, database remains empty while testing
I'm running some unittests that need manual debugging. Now I run in to the problem that somehow nothing is written to the database during those tests. Is there any way to force Django (or pytest?) to commit changes directly when executed so I can actually see what is in the database when I hit a breakpoint? my_object = SomeDefaultDjangoModel() my_object.some_random_text = 'Just adding some data' my_object.save() foo = 'bar' <= Hitting breakpoint here. Doing a manual SQL query against my database return 0 rows. How can I make this work? -
How to save all items to memcached without losing them?
In [11]: from django.core.cache import cache In [12]: keys = [] In [13]: for i in range(1, 10000): ...: key = "Key%s" % i ...: value = ("Value%s" % i)*5000 ...: cache.set(key, value, None) ...: keys.append(key) ...: # check lost keys ...: lost = 0 ...: for k in keys: ...: if not cache.get(k): ...: lost += 1 ...: if lost: ...: print "Lost %s in %s" % (lost, i) I am using Django, memcached with python-memcached with below cache settings: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', } } For the above program, I started losing caches from i=1437. Can you please tell me what to do so I can save all items to cache ? -
Handling celery task dependency
I'm developing using Python and Django and using celery for async tasks. I have two celery tasks c_task1 and c_task2 being called at completely different instances. Multiple other code execution happens between the two calls. c_task2 should start only after c_task1 ends. I don't want to block the celery worker by the putting the "wait for c_task1 to finish using loop or so" logic inside c_task2. What would be a decent way to do this ? -
Issues with using swagger using Django Rest Framework
I just started using swagger go my API documentation. I followed your docs , but more then half of the urls were excluded by swagger. As you can see in image below, it is showing some urls but few urls are excluded and the urls displayed by swagger do not include full functionality like there is no body part to test the end points. If you click Try it out! it will send the request with blank params (no body to edit request params). Below is my urls file. I have used include() to includes my app urls may be that is the reason but then how it is showing some urls and excluding some. urlpatterns = [ url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')), url(r'^api/v3/', include('identify.routers_v3', namespace='v3')), # swagger schema url url(r'^docs/', schema_view), ] I have also checked the console and there are no errors in console. Also I am using djnago rest APIView -
Django internationalisation: POST is redirected as GET
I have an Android native app that uses Django as its backend. The sign up page is a native Android Activity, with all information packaged into JSON and sent as POST to the server. Everything worked fine till I enabled internationalisation (i18n). Now when I send POST I see the following messages on the server: [12/Oct/2016 07:27:06] "POST /student/activation HTTP/1.1" 302 0 [2016-10-12 07:27:06] DEBUG <WSGIRequest: GET '/he/student/activation'> [12/Oct/2016 07:27:06] "GET /he/student/activation HTTP/1.1" 500 51426 The 2nd line comes from my view that simply logs the incoming request. Now the view expects POST and can't handle GET, thus the 500 error in the 3rd line. So my conclusion is that the POST comes in and django appends language specific prefix and issues redirect to the new URL, but instead of POST redirect goes out as GET. How can I ensure redirect is POST with all its JSON data intact? Thanks. -

How to split template for the given link for pagination :
https://django-endless-pagination.readthedocs.io/en/latest/twitter_pagination.html Given above is a link for twitter-style pagination in django. I'm trying to implement the same in my app but can't understand the splitting of template. I'm giving here the code of my html page for which I want to apply the pagination . Can anyone please help me by answering to what should I write in the two templates one is entry_index.html and other is entry_index_page.html(as mentioned in the link) according to my html code?

Celery (Django) + RabbitMQ + nodejs server exchange data
I have an Django project using Celery with RabbitMQ broker. And now I want to call django (celery) task from NodeJS server. In my NodeJS I'm using amqplib. Which is allow me to send tasks to RabbitMQ: amqp.connect('amqp://localhost', function(err, conn) { conn.createChannel(function(err, ch) { var q = 'celery'; ch.assertQueue(q, {durable: true}); ch.sendToQueue(q, new Buffer('What should I write here?')); }); }); My question is what format celery use? What should I write to Buffer to call celery worker? For example, in my CELERY_ROUTES (django settings) I have blabla.tasks.add: CELERY_ROUTES = { ... 'blabla.tasks.add': 'high-priority', } how to call this blabla.tasks.add function? I've tried many ways but celery worker giving me error: Received and deleted unknown message. Wrong destination?!? -

How do I keep an initial field value in a Django form
In my django form I have an object_id that is a hidden UUIDField: class MyForm(forms.Form): object_id = forms.UUIDField(widget=forms.HiddenInput) In my view, I populate this id field with an initial value. form = MyForm(initial={'object_id': pk,}) The idea is that I pass a primary key to the form and then get it back again when the for is submitted. That works. But what if the user tampers with the hidden field? To prevent this I set disabled=True on my object_id, which according to the documentation means that the initial value should be respected (although perhaps this only means an initial value defined on the field, rather than one defined on the form, through the view?). Unfortunately the result is that now my object_id returns a None object. So the question is, should disabling a field mean that it doesn't return a value. If it does, is there any way to ensure that a hidden value does a safe round trip through a submitted form? -
howto create fronted add/list/delete/update/ in django
I am new to Django and would like to create a sortable ListView (just like the Lists in Django Admin) for an array of object-instances. The objects themself are non Django-Models and are pre-populated in an array before showing the view. I've got a basic ListView working (https://docs.djangoproject.com/en/1.7/topics/class-based-views/), but the important question remains: *How do I make it sortable? * Can you give me to some examples to check out how to implement a sortable ListView? -
How to provide current time to DateTimeFields in Django fixtures?
I am trying to create a JSON fixture for one of my Django models. The model is quite simple: class Tag(models.Model): tag = models.CharField(max_length=50, null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) My fixture is also simple: [ { "model": "myapp.tag", "pk": 1, "fields": { "tag": "Test 1" } }, { "model": "myapp.tag", "pk": 2, "fields": { "tag": "Test 2" } } ] Unfortunately I get the following error when trying to run the fixture: IntegrityError: NOT NULL constraint failed: myapp_tag.created_at So it looks like auto_now_add=True doesn't get called when a fixture is run. I don't want to hardcode some date as that seems weird. (I also think hardcoding the PK is weird.) Is there any way to get the created_at date to automatically use today? And as a bonus, can the PK automatically auto-increment? Thanks for your help. -
Switching DEBUG and ALLOWED_HOSTS in settings.py automatically with Django
I think I applied DEBUG and ALLOWED_HOSTS to settings.py as the situation demands with if statements before. But I forgot how. Now, I chenge DEBUG and ALLOWED_HOSTS everytime I upload my project to heroku. For instance, under the local environment, DEBUG = True ALLOWED_HOSTS = ['*'] when I upload, DEBUG = False ALLOWED_HOSTS = ['something.herokuapp.com'] But, I feel tiresome about changing these. Would you please teach me how to change these settings automatically, I mean, the way to make the server apply or interpret these settings automatically? Django-1.9.2 -
Perform actions on server after CircleCI deployment
I have a Django project that I deploy on a server using CircleCI. The server is a basic cloud server, and I can SSH into it. I set up the deployment section of my circle.yml file, and everything is working fine. I would like to automatically perform some actions on the server after the deployment (such as migrating the database or reloading gunicorn). I there a way to do that with CircleCI? I looked in the docs but couldn't find anything related to this particular problem. I also tried to put ssh user@my_server_ip after my deployment step, but obviously it doesn't work. Here is what my ideal circle.yml file would look like: deployment: staging: branch: develop commands: - rsync --update ./requirements.txt user@server:/home/user/requirements.txt - rsync -r --update ./myapp/ user@server:/home/user/myapp/ - ssh user@server - workon myapp_venv - cd /home/user/ - pip install -r requirements.txt -

Why does django insert padding and characters into my html file?
Over the last few days I've been experimenting with Django. I've had some issues with random characters (notably '<') and what I would describe as padding appearing in my html files. I decided to ignore using Django and rewrote a test template with just html/css. It worked perfectly, and I thought that perhaps it had been an error in my HTML/CSS, until I put the Django template code back in. Now, even though I've removed the Django code and moved the files outside of the root directory for the project, the problem persists. I can't see why this has happened, and the error appears in Firefox, Chrome and even IE. The source looks right in these browsers, but right click -> inspect in Google Chrome shows there's something not right. Here's the HTML: <!DOCTYPE html> <link rel="stylesheet" type="text/css" href="main.css" /> <html> <head> <title></title> <meta charset="utf-8" /> </head> <body> <div id="container"> <div id="header"> <div class="nav"> <ul> <li><a href="#">Link 1</a></li> <li><a href="#">Link 2</a></li> <li><a href="#">Link 3</a></li> <li><a href="#">Link 4</a></li> <li><a href="#">Link 5</a></li> </ul> </div> </div> <<div id="content"></div> <div id="footer"></div> </div> </body> </html> And the CSS: body { margin:0; padding:0; height:100%; } #container { min-height:100%; position:relative; width:50%; margin:0% 25% 0% 25%; } #header … -

including/passing slug and pk(or any other variable) in url conf
Currently my config looks something like this: urls.py: url(r'^(?P<slug>[-_~\w]+)/$', SomeDetailView.as_view(), name='detail'), views.py is plain vanilla like so: class GetDetailView(SomeDetailViewMixin, DetailView): model = Dummy template_name = "detail.html" and html is like so: <h2><a href="{% url 'detail' i.slug %}" rel="nofollow"></a>Text</h2> .. and everything works perfectly fine. However, what I am now looking for is to pass another variable (such as pk - say var2) via the html to the url conf. So, something like: html (which is a ListView): <h2><a href="{% url 'detail' i.slug i.var2 %}" rel="nofollow"></a></h2> and urls.py something like: url(r'^(?P<slug>[-_~\w]+)/$', SomeDetailView.as_view(), kwargs={'var2': var2}, name='detail'), is something along these lines possible? What I do not want is to include the var2 in the url itself (because var2 is ugly)... I remember doing something along these lines a year ago, but my memory has let me down again... Would appreciate any help on this... -
Improving table rendering speed in Django templates (using endless pagination)
I am facing a terrible issue of VERY SLOW rendering of my table. It contains only 3000 records (yes, three thousand !!!), and it takes me 19 seconds (!!!) to render the table.
