After source ./bin/activate, on doing a which python3.5 I get the following response /path/to/virtualenv/bin/python3.5 I am using Django 1.10.5 which according to their documentation supports Python 3.5.

Working around SQLite's lack of named parameter support
Django's documentation on objects.raw() says the following about using named parameters: Dictionary params are not supported with the SQLite backend; with this backend, you must pass parameters as a list. I use SQLite when running unit tests in our codebase because it's ridiculously fast in comparison to our real database backend. But since it doesn't seem to support named parameters, I cannot write tests for this piece of functionality. Is there a clean generic way to work around this limitation? As in, without resorting to hacks that could expose code to SQL injection? -

Multiple Databases --Migrations
I am using 2 postgres databases in my django app. 'newpostgre': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'new_postgre2', 'USER': 'tester', 'PASSWORD': 'password', 'HOST': 'localhost', 'PORT': '', }, 'newpostgre2': { 'ENGINE': 'django.db.backends.postgresql_psycopg2', 'NAME': 'new_postgre3', 'USER': 'tester', 'PASSWORD': 'password', 'HOST': 'localhost', 'PORT': '', }, I have a very simple model class Check1(models.Model): title = models.CharField(max_length=100) I had run python manage.py migrate --database=newpostgre python manage.py migrate --database=newpostgre2 when I open my new_postgre2(for newpostgre) database in postgre, I can see my Check1 table there. But in my new_postgre3(for newpostgre2) database in postgre, no Check1 table is there, only those initial migrations are there. Why I can't see my table in new_postgre3 when migrations have been successfully made? -

Wrong number of constrains when refactoring modules to another app
After refactoring some models in a bloated app (everything in appname/models.py) into a subfolder application (some of the models in appname/subapp/models.py) and running makemigrations, I'm getting the following error when running manage.py migrate: ValueError: Found wrong number (2) of constraints for appname_modelname1(modelname2_id) Getting rid of all migrations and starting over would be one option, but then I'd have to manually edit all existing production databases. Are there any alternatives to make the migrations apply smoothly? -
Ways to implement google adwords-esque geo targeting functionality
Im looking for a way to implement something similar to google adwords geotargeting functionality (obviously less intense) Just something that takes user input as an HTML form, be able to select different countries/states/cities and somehow saves them to a database. If it helps, I am currently trying to do this in Django using python. But I'm guessing that any ideas or concepts will still be helpful. Right now, all I have on the drawing board of how to implement this, is just a giant table in MySQL with many many boolean columns # this is in Django, btw class GeoTargetSelection(models.Model): chose_canada = models.BooleanField() chose_china = models.BooleanField() ... Obviously this is not very salable, nor does it allow for states/cities. Does anyone have any ideas for the model/form/where to get list of states/cities/countries/etc? Anything will be appreciated -

Django : methode in models vs methode in views
I ask myself this question, what the difference and the more performant between a methode in models.py and views.py ? Example 1: models.py: class Counter(models.Model): number = models.PositiveSmallIntegerField(default=0) def add_one(self): self.number += 1 self.save() views.py from *xxx* import Counter def count(request): c = Counter() c.add_one() c.save() return render(request, *xxx*) Example 2: models.py: class Counter(models.Model): number = models.PositiveSmallIntegerField(default=0) views.py from *xxx* import Counter def add_one(nb): nb += 1 return nb def count(request): c = Counter() c.number = add_one(c.number) return render(request, *xxx*) My example is a little bit simple, but what the difference in the real life with big methode and so many variables ? Its have an impact on the performance of the server ? Did he have conventional or preference to choose one way ? -
downloadable file link in django tables
I am using django-tables2 and have a view which basically should allow user access to the data store. My table model has a link column is as follows: class DummyTable(tables.Table): download = tables.LinkColumn('dummy_download', args=[tables.A('pk')], orderable=False, empty_values=(), verbose_name='') The rendering of the link column is done as follows: class Meta: model = DummyModel attrs = {'class': 'paleblue'} def render_download(self): url = static('cloud-download.png') media_root = settings.MEDIA_ROOT href = media_root + "/mask.nii.gz" return mark_safe('<a href="' + href + '"><img src="' + url + '"></a>') So basically I have some data in my /media folder which I would like to allow the user to download when the link is clicked. However, I am unable to generate the correct link in the render_download method. Putting the link simply as I have it does not initiate any download even though it seems to point to the correct file location (locally). Also, I am not sure if this will work when someone connects remotely. I have a feeling it should call some reST API internally to initiate the download but I am not sure how to achieve this. The settings.py file configures the media settings as follows: MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/' -
Disable model saves without going though DRF
I need to disable model saves unless the data is coming via a DRF serializer. I'm not sure the best way to do this. One way i can think of is override the save method and add some check which is fulfilled by the data coming from drf. Is there a better way to do this? -
Swift: Passing Password as parameter in alamofire to Django API
I am pretty new to django, so please bear with me. I had created a django rest api is linked to a postgresql database. I tested out the responses by hitting the urls via a python post request. I then proceeded to create an iOS app which communicates with the API through the Alamofire framework(meant for http requests). I created a dummy user in my postgres auth db with an unencoded password and am able to generate a token which I then use to hit the remaining urls. My question basically is this: Is it a good practice to send my password as a parameter without encoding it (maybe using md5)? Basically, how does djangorest perform authentication? Will it decode my password before it checks the authentication backend or does it straight up try to match the exact characters that are sent? Should I encode my password before I pass it? -

Django REST Framework and FileField absolute url on the same field
DRF serializes by default a filefield or imagefield path to it's relative path. Like in this questions Django REST Framework and FileField absolute url I know it's possible to generate a custom field called i.e. "file_url" and serialize the full path. But is it possible to serialize it in the same field? like: class Project(models.Model): name = models.CharField(max_length=200) thumbnail = models.FileField(upload_to='media', null=True) class ProjectSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Project fields = ( 'id' ,'url', 'name', 'thumbnail') class ProjectViewSet(viewsets.ModelViewSet): queryset = Project.objects.all() serializer_class = ProjectSerializer { "id": 1, "url": "http://localhost:8000/api/v1/projects/1/", "name": "Institutional", "thumbnail": "ABSOLUTE URL" } -

is db_column changing my mongodb field?
i'm new here. I'm having a problem with django where i have 'type' which is a reserved keyword as a column in mongodb. Based on answers in stackoverflow, i solved it by applying https://docs.djangoproject.com/en/1.10/ref/models/fields/#django.db.models.Field.db_column My code currently looked like this discountType = StringField(required=True, db_column='type') However, the problem is the field 'type' was changed to 'discountType'. Is there a way to prevent the model from changing the field name? TQ in advance
