These are my models. class Ofac_Sdn(models.Model): number = models.IntegerField(blank=True, null=True) name = models.CharField(max_length=200, null=True) b_i = models.CharField(max_length=250, null=True) programe= models.CharField(max_length=250, null=True) last_name= models.CharField(max_length=250, null=True) more_info = models.CharField(max_length=250, null=True) vessel_call_sign = models.CharField(max_length=250, null=True) vessel_type= models.CharField(max_length=250, null=True) vessel_dwt = models.IntegerField(blank=True, null=True) tonnage = models.IntegerField(blank=True, null=True) vessel_flag = models.CharField(max_length=250, null=True) vessel_owner= models.CharField(max_length=250, null=True) dob_aka= models.CharField(max_length=250, null=True) This is the model of a row from my CSV: 36,AEROCARIBBEAN AIRLINES,-0- ,CUBA,-0- ,-0- ,-0- ,-0- ,-0- ,-0- ,-0- ,-0- I have tried until now this example, but i receive an error saying: ModuleNotFoundError: No module named 'settings' If someone could help, I would owe you a lot as i am stuck here!

Accessing django database from python script
I'm trying to access django app db from within python script. So far what i did is: import os import django from django.db import models os.environ.setdefault("DJANGO_SETTINGS_MODULE", "m_site.settings") django.setup() from django.apps import apps ap=apps.get_model('py','Post') q=ap.objects.all() for a in q: print(a.title) There is application in django called 'py' where i have many posts ( models.py -> class Post(models.Model) ). I would like to habe possibility to access and update this db from python script. So far script above works fine, I can insert, update or query but it looks like it is separated db and not db from django 'py' application. Am I doing something wrong or missing something ? Any help would be very appreciated. Regards -
Non-deterministic results when testing django haystack with elasticsearch
I am functional testing results returned by django-haystack with elasticsearch. I'm having different results when running a test. Sometimes the test pass, sometimes it doesn't. I can't figure out why this happens. My test class first creates entries in the test database, and then call the manage.py rebuild_index, using StaticLiveServerTestCase setUp method. In the end I call manage.py clear_index. I won't go to reproduce here all django code for search indexes, _text.txt's because the django-haystack/elasticsearch code is working. I'm wondering if it's a problem of synchronization between the database entries created and the call to rebuild_index. Basically, in my tests I do this class SearchTest(FunctionalTest): def setUp(self): super(SearchTest, self).setUp() # this make the entries in database self.rebuild_index() def tearDown(self): super(SearchTest, self).tearDown() call_command('clear_index', interactive=False) So, what could be happening? -
Django Rest Framework object with relationship
How do I find an object with relationship and how to save an object in relationship with Django Rest Framework? I looked in the documentation and found something similar to this class UserSerializer(serializers.ModelSerializer): profile = ProfileSerializer() class Meta: model = User fields = ('username', 'email', 'first_name', 'last_name', 'profile') class ProfileSerializer(serializers.ModelSerializer): class Meta: model = Profile fields = ('nome_empresa', 'cnpj') -
Amazon S3: Creating a route alias for a Django app
I have a Django App running on Heroku and I'm using Amazon S3 to store and serve static assets. I'm also using it to store media files. When sending a link to a file to a user it generates it like this: https://s3-eu-west-1.amazonaws.com:443/my-bucket-name/path/to/file.pdf I would prefer it if it looks like the file is stored on my domain, so making it accessible from www.mysite.com/path/to/file.pdf Is this possible? I'm thinking if I use something like files.mysite.com/path/to/file.pdf it may be possible? Alternatively I will have to set up a redirect. -

Celerybeat does not start in detach mode

Is there a better way to get and display data from a related object aside from creating a dictionary?

The only way I could figure out how to do this was to create a dictionary using the code shown below. class Homeowners(DetailView): def get(self, request, **kwargs): salespersons = WhoAmI.objects.all() homeowners = SolarClient.objects.all().order_by("client_owner") #the name 'objects' is the Manager rangers = {} for e in salespersons: k = salespersons.get(id = e.id) v = k.solarclients.all() rangers[k] = v return render(request, 'homeowners.html', {'homeowners': homeowners, 'salespersons': salespersons, 'rangers': rangers }) I then iterate over the dictionary using: {% for key, values in rangers.items %} ... display salesperson {% if values %} {% for v in values %} .... display clients {% endfor %} {% else %} ... display "No Clients" {% endif %} {% endfor %} Is there a more efficient way to do this? … -

Change grouping of an specific exception in sentry (django)
I use raven with my django web application and i want to prevent an exception from excessive grouping as described in documentations here while preserving default behavior for other exceptions. More concretely I have a code snippet like this somewhere in my app: raise Exception('Nothing done for catalog #' + str(catalog_id)) in sentry i see exceptions for different catalogs grouped together because it rolls them up based on stack-traces. As i understood from docs i should use something like: client.captureException(fingerprint=['{{ default }}', str(catalog_id)]) but i don't know where in my code it should be used.
