Django: Store gmt time in database table instead of local time
In my customer model I have two datetime fields for storing created and updated time. datetime_created = models.DateTimeField(auto_now_add=True) datetime_updated = models.DateTimeField(auto_now=True) When I create a customer, Now it is storing the local time in the database, When I get this customer data through API, It is returning the datetime in gmt time. This is fine. But I want to save the gmt time in the database. I think storing local time in database is not a good practice. Date settings in settings.py file is LANGUAGE_CODE = 'en-us' TIME_ZONE = 'UTC' USE_I18N = True USE_L10N = True USE_TZ = True I have already installed "pip install pytz" module and my database is postgresql. -
400 using Axios to make a post request to Django Rest Framework
I'm working with learning some javascript to make a post to a little rest API I created with django rest. I have a post that works when I was working with jQuery but now I am reimplementing using Vue.js and am hitting a snag. When I do the below post request I get a 400 error and am not sure what I am missing. I would imagine something with my header is incorrect? Any advice would be welcome. axios({ method: 'post', url: '/api/matches/', data: JSON.stringify(data), headers: { "X-CSRFToken": csrfToken, "Content-Type": "application/json" } }) jQuery post for reference: $.ajax({ type: "POST", url: "/api/matches/", data: JSON.stringify(final_data), success: function() {}, error: function(err) {console.log(err)}, contentType: "application/json; charset=utf-8", dataType: "json", crossDomain:false, beforeSend: function(xhr, settings) { xhr.setRequestHeader("X-CSRFToken", csrftoken); } }); -

Django, m2m count annotation related model with condition
so my models: class User(models.Model): username = models.CharField(max_lenght=255) class Group(models.Model): users = models.ManyToManyField('User') class ActiveGroup(models.Model): group = models.ForeignKey('Group', null=True, blank=True, default=None) user = models.OneToOneField('User') So the deal is every user can be a member of any group ( which is represented by m2m field on Group model). But can be active member in only one of them at the same time ( thats why oneToOneField relation on activegroup model). Problem: need to make a queryset for Group models with count of users which are active. so its suppose to be like SELECT group.id, COUNT( SELECT COUNT(*) FROM activegroup WHERE activegroup.group_id = group.group.id ) as users_count FROM group. I've tried django.db.models Case and When things but nothing helps. -

Django filename for uploaded file
I am working on some legacy code and recently I migrated the app from Django 1.5 to 1.8 . I have this model where the user uploads files. This is the model: class Document(models.Model): file = models.FileField(upload_to='common/') user = models.ForeignKey(User,on_delete=models.CASCADE,related_name='documents') created = models.DateTimeField(default=timezone.now) modified = models.DateTimeField(auto_now=True) del_f = models.BooleanField(default=False) class Meta: ordering = ['-created',] app_label = 'dms' def save(self, *args, **kwargs): ''' On save, update timestamps ''' if not self.id: self.created = timezone.now() self.modified = timezone.now() return super(Document, self).save(*args, **kwargs) @property def filename(self): return os.path.basename(self.file.name) I am trying to change the filename property. The filenames tha are generated now are these: I want that weird "_WtyGVsQ" before the file extension to be replaced with an ascending number(the file extension stays). For example if I upload the file "data_conversions.ods" 2 times ,the filenames that will be generated will be: data_conversions_1.ods data_conversions_2.ods ..and so on... The odd fact is that in 1.5 the filenames where uploaded like that (with the _1,_2 ascending). Any suggestions? -

Check the encoding type on the form.']} What I found is validate_image is never called. What might be the problem? -
Django REST framework auto decode while rendering URLs
I'm using a ModelViewSet with HyperLinkedSerializer to show my objects in the browsable APIs. The problem is that one field of them is an URL like "download_url": "https://f1234567.s3.amazonaws.com/backup/89045%40BASE-175", Copying this URL in the problem, it successfully downloads the target file, however clicking on this link from the DRF it goes to https://f1234567.s3.amazonaws.com/backup/89045@BASE-175 where it decoded the %40 back to @ My question is how to fix this and make the links in the browsable APIs safe for clicks and which part is responsible for auto decoding the URLs. BTW, requesting the same API URL http://127.0.0.1:8000/api/v1/backup_files/14/ but with JSON content type, the download_url value is valid with %40 not @. -
DRF making DateTimeField naive without considering default timezone
The default timezone is TIME_ZONE = 'America/Chicago' and USE_TZ = False In the request data, I have time field whose value is something like this: '2017-04-05T14:42:52.472+05:00' And when I do this: serializer = self.get_serializer(data=data) if serializer.is_valid(): ... that time field is converted to this inside validated_data: 2017-04-05 09:42:52.472000 That is, it is making the time naive. However, it is not considering my default timezone. I would expect it to convert the time to Chicago time first and then make it naive to this: 2017-04-05 04:42:52.875000 just like how django.utils.timezone.make_naive() works. I am solving this by using that make_naive. However, I don't think this is a good solution. Serializer: class LocationSerializer(serializers.ModelSerializer): time = UnixTimestampField() class Meta: model = Location fields = ( 'latitude', 'longitude', 'time' ) def validate(self, attrs): user = self.context['request'].user if user.is_authenticated(): attrs['tracking_id'] = user.tracking.id attrs['device_id'] = user.current_device.id return attrs Is this the default behavior of DRF? What is the proper way of solving this?
