How do I display time since creation instead of time created in Django
I am working on displaying a post in django and currently to display when the post was created, I am using {{ instance.post_created }}. I was wondering if there was anyway I could get it to say "2 days ago" if the post was made on the 28th of Jan and the person was viewing it on the 30th of Jan as an example. Thanks for any help, Will -
Django: How to refresh table after filtering without refreshing the whole page?
The root of the issue is how to refresh the filtered table dynamically, without refreshing the whole page. I am almost novice in python/html/css, so please make some comments like for a newbie [Thanks]. After some research on StackOverFlow, I found that it could be made with js, but I have almost no experience with js and I don't know how to use it in Django. Is there any possibility using only Django tools? And how efficient it would be? Maybe you can provide some examples of resolving the issue. Here is the model: class Player(models.Model): last_name = models.CharField( null=True, blank=True, max_length=255, verbose_name="прізвище" ) first_name = models.CharField( null=True, blank=True, max_length=255, verbose_name="ім'я" ) city = models.ForeignKey( City, on_delete=models.SET_NULL, null=True, blank=True, verbose_name="місто" ) rating = models.PositiveIntegerField( null=True, blank=True, verbose_name="рейтинг" ) rank = models.ForeignKey( Rank, on_delete=models.SET_NULL, null=True, blank=True, verbose_name="ранг" ) local_rank = models.ForeignKey( LocalRank, null=True, blank=True, on_delete=models.SET_NULL, verbose_name="розряд" ) def __str__(self): if self.last_name and self.first_name: return self.last_name + ' ' + self.first_name elif self.egd_last_name and self.egd_first_name: return self.egd_last_name + ' ' + self.egd_first_name else: return self.id I am using django-tables2 to render the table: class PlayerTable(tables.Table): full_name = tables.LinkColumn( accessor="__str__", verbose_name="Прізвище та ім'я", order_by="last_name", viewname='UGD:player_info', empty_values=(), args=[A('pk')] ) local_rank = tables.Column( accessor="local_rank.abbreviate", order_by="id" … -
Rendering and post that data JQuery
I am a bit stuck here and would like to get some input from the community. So I have a HTML page that contains a table, one of the columns is solely populated with checkboxes, underneath this table is my pseudo 'submit' button, when this is clicked it will scan the table and get the keys of any checked checkboxes this is all fine. The part I cannot get to work is with this rendered data I wish to post (move it) to another page/template. What I have tried: To do this I have tried posting the data to a view using AJAX (which worked) but I then realised and read that I could not redirect and render a new template in my AJAX call. A form with an invisible field. I set the button to an actual submit button and when the data was rendered I plugged it into the forms field. The logic was all fine however I couldn't get it to redirect, 'action="myurl/"' just changed the URL but kept the same template, it ignored the urls.py file telling it to load a new view+template I also tried to post through JQuery but this gave me a CSRF … -
Django - callback whenever data has changed in admin
I'm working on a project where I use Django's admin "power" to manage a few models, which are to be displayed in a visualization (made with JavaScript). Javascript can read the data in json, so I need a way to convert the data for my models to json. I'll use Django's serialization tools. I figure it makes more sense to generate a json file only when a create / edit / delete action has been performed on the admin side. How can I make sure a callback (to do the serialization) is triggered every time the data changes in the admin side ? -

Wagtail ModelAdmin with list_filter error: FieldDoesNotExist: Region has no field named 'p'
I've got a model I'm exposing through Wagtail's modeladmin that works until I try to apply a list_filter including a ForeignKey. I've got a self-referencing model (to store Counties, Cities, and Towns) called Region that I'd like to be able to create a filter on by the Parent level. I'm running Wagtail 1.8.1 on Django 1.10. Here's the model: class Region(models.Model): """ Tree of regions and sub-regions. """ name = models.CharField(max_length=255) parent = models.ForeignKey( 'Region', blank=True, null=True, ) class Meta: unique_together = ('name', 'parent') def __str__(self): return '{0}'.format( self.name, ) And the ModelAdmin from wagtail_hooks.py: class RegionAdmin(ModelAdmin): model = Region menu_icon = 'doc-full-inverse' empty_value_display = 'ROOT' list_display = ('parent', 'name') list_filter = ('parent') modeladmin_register(RegionAdmin) It works fine if I comment out the list_filter line in the class RegionAdmin. The documentation says it can take a ForeignKey in the list. Am I missing something obvious?

Can I configure Django project within pydev project in eclipse?
I have a python project, with a django project whitin it. That means the root of the django project is a directory inside my project. I previously worked with pycharm, and could define the django root as a django project- and then enjoy the benefits of django whitin my project. I am now using eclipse neon, and it seems the only thing i can do is define the project root as django project. This results in 'errors' eclipse think i have- since the imports from django (which works on production mode) are not recognized by eclipse. Example: project_root dir1 dir2 files django_root django_app_modules django_sub_module Now, if I have in my code imports from: django_app_modules.django_sub_module, eclipse won't recognize them since it doesn't find them inside the project root, unlike pycharm where it knew to look for them inside the django_root. I can't believe eclipse doesn't support this as well, but I just can't find how to do it. Thanks -
Lets Encrypt multiple nginxconf
I have some questions regarding the use of Let's Encrypt with multiple nginxconf files. .well-known location block Do I need to put this location block in every nginxconf file, or just in the default nginxconf? location ~ /.well-known { allow all; } My default config file is used for showing the "Nginx is working" page. My other serverblocks, which are in seperate nginxconf files, are used for binding a specific application to a specific domain. What is my document root? I serve multiple Django applications on my server. In the Let's Encrypt tutorial they are talking about a document root. Should this be a single document root for all my applications/certificates (for example /var/www/html) or does each application have it's own document root (for example the root folder of my Django application)? Note: my Django application are NOT in /var/www/html, but in a directory WITHIN my home directory. -

Django model choices using other models
Schedule is my model that holds all my events in one place (Meetings, vacation, birthdays, etc) but i also want each of these events to be models so that they can be viewed in their own space. How would i put the events as choices so that when I add a specific event to my schedule, in this case - a reminder, it adds the reminder to my schedule AND reminders but not to vacation or birthdays. This is what i have so far, I believe I would put the individual events into SCHED_CHOICES but i do not know how I would call the models inside of this to make it update and save the event to the specific model and not only the schedule model. class Schedule(models.Model): SCHED_CHOICES = ( ) user = models.ForeignKey(User) time = models.DateTimeField() -
Get Celery logs in the same place as 'normal' Django logs and formatted by a Django formatter
I try to find a way to gather the logs generatd from inside async functions called through Celery, inside the same handler that I use to log 'non-celery' django functions.

Mocking time issue in django test: time seems not to be frozen using freezegun
I'm writing here a functional test to check if my API throttling is working as expected (will be rest at the beginning of every month). Testing Class: class ApiThrottlingTest(ThrottlingBaseTest): def test_throttling_purchaser_case(self): now = datetime.datetime(year=2015, month=1, day=10, hour=6, minute=6, second=3) last_day_of_current_month = datetime.datetime(year=2015, month=1, day=31, hour=23, minute=59, second=59) first_day_of_next_month = datetime.datetime(year=2015, month=2, day=1, hour=0, minute=0, second=0) with freeze_time(now) as frozen_datetime: for i in xrange(3): resp = self._project_details_request() self.assertEqual(resp.status_code, 200) resp = self._project_details_request() self.assertEqual(resp.status_code, 429) frozen_datetime.move_to(last_day_of_current_month) resp = self._project_details_request() # the test fails at this level self.assertEqual(resp.status_code, 429) frozen_datetime.move_to(first_day_of_next_month) resp = self._project_details_request() self.assertEqual(resp.status_code, 200) The test works fine if: last_day_of_current_month = datetime.datetime(... second=0) but will fail if: last_day_of_current_month = datetime.datetime(... second=59) After debugging it seems like the time module used in DjangoRestFramework throttling.UserRateThrottle is in somehow giving a value that's always ahead of the fronzen time in my test, which is causing a precision issue of some seconds. Based on FreezeGun Doc: Once the decorator or context manager have been invoked, all calls to datetime.datetime.now(), datetime.datetime.utcnow(), datetime.date.today(), time.time(), time.localtime(), time.gmtime(), and time.strftime() will return the time that has been frozen. But it looks like im my case time.time takes correctly the start time of the mocked datetime but then keep changing over … -
