Setting Initial Field in Django
I have a model form and I am trying to pass an initial value to one of the fields when I call the form from the view. My view has the following: threadform = ThreadForm(text="hello") The model form is as below: class ThreadForm(ModelForm): class Meta: model = Thread fields = ['title'] def __init__ (self,*args, **kwargs): self.fields['title'].initial = kwargs.pop("text") super (ThreadForm, self).__init__(*args, **kwargs) This will give the error "ThreadForm" has no attribute 'fields'. If I reverse the super call then get "init() got an unexpected keyword argument 'text'". Please can someone help as I can't find any information on the correct way to do this as others seem to be setting a hard coded initial value, but mine is dynamic as I want to replace the literal "hello" with data from a model. -

Django testing - test the view which handles an ajax call
In testing Django, the view is returning 200 code but not sending any error message related. def ajax_view(request): msg = '' if request.is_ajax(): username = request.POST['username'] user = User.objects.get(username=username) msg = 'user exists' return HttpResponse(msg) In tests.py response = self.client.post(reverse('ajax_view'), data={'username': 'hello'}) self.assertEqual(200, response.status_code) self.assertContains(response, 'exist') It seems it is not going through the request.is_ajax()..

Js or Django? Opinions please.
Seeking opinions. I just want to say that in no way am I over looking the amount of work that would need to be put in to even become decent in any of these disciplines, I'm trying to understand if my logic of this road map is technologically feasible and appropriate. Started down the road of learning python for ease of learning and wanted to tinker with ardiuno's, rasp pi's other IOT's. Also emerging fields python seems to be strong in, blockchain (smart contracts) A.I., machine learning and robotics all seem challenging but interesting. But being realistic I found it maybe a "faster" road if I learned web development to get a job as a dev while I increase my skills in those other area's mentioned. That's where I came across Django. Knowing my interests stated above I figure it be beneficial to learn HTML5/CSS and Django instead of JS to become that web developer since Django is a framework for python logic for websites. So because I've been learning Python, it seems to me, time wise, that Django would allow me to be a web developer while still being able to hone my python foundation for projects ahead as … -
Custom user model and table in django

HTML : Django Form validation and loading gif "onclick"

Django QuerySets, Annotate Sum of Filtered Related Objects field without returning NoneType
Is there a way to perform annotation sum on filtered related model fields without returning None when all the related results have been filtered out? For example, with the models below, I would like to have the yearly and monthly donation sums but excluding donations that were not successful or were refunded. I started using Case/When to avoid the problem of receiving None rather than 0 for users with no donations. But I still need to excluded unsuccessful and refunded donations. Reading Django's docs, I found you can set a custom _base_manager, but then it says "Base managers aren’t used when querying on related models". Is there another approach I could take? models.py class Profile(Model): user = OneToOneField( User, on_delete=CASCADE, related_name='profile' ) has_donor_access = BooleanField( default=False ) ... objects = Manager() account_objects = AccountManager() def __str__(self): return "{0} :: {1}".format( self.user.get_full_name(), self.user.get_username()) class Donation(Model): user = ForeignKey( User, blank=True, null=True, on_delete=SET_NULL, related_name='donations', verbose_name=_('donor') ) creation_date = DateTimeField( auto_now_add=True ) amount = DecimalField( decimal_places=2, max_digits=9 ) is_success = NullBooleanField( default=True ) is_refunded = NullBooleanField( default=False ) ... def __str__(self): user_profile = self.user.profile if self.user else "Anonymous" return "{0} :: ${1} :: {2}".format( user_profile, self.amount, self.creation_date) managers.py class AccountQuerySet(QuerySet): def with_donation_stats(self): a_month_ago … -

Uploading Json to django model database results in Key Error
I have a custom manage.py command which I am using to upload a json file (a list of dictionaries) to my model. It appears to upload two records fine, but then throws a key error: KeyError: 'headline' My code is as follows: class Command(BaseCommand): def handle(self,*args,**options): filename = '/DoJ_Data_01-12-18.json' newpath = str(Path(home))+filename with open(newpath) as json_file: data = json.load(json_file) for d in data: q = doj(headline=d['headline'],topics=d['topics'],text=d['text'],url=d['url'],date=d['date']) q.save() As far as I can tell the json is valid. What am I missing?
