How to return a specific response from DRF Serializer?
If you look at the try/except block under is_valid() method, I'm trying to check if an object exists and if so, return a 202 error. My question is can I directly return a a response from the serializer or do I need to raise a specific exception and then handle the exception in the views? class CreateJobSerializer(GenericSerializer): class Meta: model = Job fields = ('name',) validators = [] def is_valid(self, raise_exception=False): if hasattr(self, 'initial_data'): super(CreateJobSerializer, self).clean_ids() try: Job.objects.get(name=self.initial_data['name']) return Response(serializer.errors, status=status.HTTP_202_ACCEPTED) except: return super().is_valid(raise_exception) -
Django_Tables Adding a new custom column not found in model
I have the following table: class TaskTable(tables.Table): def render_foo(self): raise Exception() class Meta: model = Task fields = ['foo'] for the following model: class Task(models.Model): priority = models.PositiveIntegerField() title = models.CharField(max_length=1024) content = models.TextField(null=True, blank=True) According to the docs, render_foo won't be executed if it is considered an empty value. My requirement is that foo is not found in the Model. How can I implement the column foo? -
Django Rest Framework use of `permissions.IsAuthenticated` rises an erro
I have a ModelViewSet and I want it to be accessed only by authenticated users, so I added the permission_classes = (permissions.IsAuthenticated), but I get an error: TypeError at /es/general/countries/ 'type' object is not iterable This is the ViewSet: class CountryViewSet(viewsets.ModelViewSet): permission_classes = (permissions.IsAuthenticated) queryset = models.Country.objects.all() serializer_class = serializers.CountrySerializer If I remove the IsAuthenticated assignment line, the ViewSet works, but with it, I get the error. I'll appreciate your help. -

Creating a password field for a custom user model in Django
In my project, I have 2 types of users. One of them is being modeled using the default Django User model, however, the other one needs to be totally custom. I do not want to extend the default one because these are very different use cases. Anyway, so far I am trying to do it this way: class CustomUser(models.Model): ... password = models.CharField(_('password'), max_length=128) ... def set_password(self, raw_password): import random algo = 'sha1' salt = get_hexdigest(algo, str(random.random()),str(random.random()))[:5] hsh = get_hexdigest(algo, salt, raw_password) self.password = '%s$%s$%s' % (algo, salt, hsh) This is of course based on the one used by Django. Now, I get what is going on. We don't really save the password, but we get the password and we use an algorithm to turn it into a weird string and save that string instead. I want to create a login view for my CustomUser. Lets say, one of my CustomUsers uses the username=admin, password=MyPassword23 to login, how can I take the string 'MyPassword23' and turn that into the weird string so I can match it and return the user? Is this actually the way these things are done? Or am I completely off the standard with my approach? Thanks … -
Nginx Is Displaying a 502 Bad Gateway Error Instead of the Django Application
I am trying to follow this tutorial (https://www.digitalocean.com/community/tutorials/how-to-serve-django-applications-with-uwsgi-and-nginx-on-ubuntu-16-04#setting-up-the-uwsgi-application-server) for deploying a django server but somehow I keep on getting 502 gateway error and I checked that the .sock file is not created though.

How to return custom status code via DRF?
If a user sends a POST request to create a job, but that job already exists - I am trying to return a 202. Instead, it is returning a 400.. views def post(self, request, format=None): serializer = CreateJobSerializer(data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) serializer class CreateJobSerializer(GenericSerializer): class Meta: model = Job fields = ('name') def create(self, validated_data): try: obj = Job.objects.create(**validated_data) return obj except: return Response(serializer.errors, status=status.HTTP_202_ACCEPTED) I assume that Job.objects.create will fail if unique=true is violated on that model, if that is the case I would expect a 202 to be returned. What am I doing wrong? Is it because the unique=true error is actually being caught during validation so create() is never actually called? -
Getting CSRF token missing or incorrect for one route but not the other
Working on React/Django and have run into an issue I can't resolve. On the front end, there is the following JS sending data to the Django API. In this case, rejectedDocuemts() is sending an array of filenames to the backend so eventually an email can be created and sent to the admin to review. Files that don't match an approved list of extensions make it on this list. This is where the error occurs. The submitDocuments is where files that meet the approved list of file extensions are submitted. The entire files object is sent to the server to be saved. This one is working perfectly fine. export function rejectedDocuments(filenames, id) { return function (dispatch) { axios.post( `${URL}/api/${(id)}/documents/upload/error`, filenames, { headers: { 'content-type': 'text/plain', 'Authorization': 'JWT ' + sessionStorage.getItem('token') } } ) } } // Creates the error state to be used in components export function submitDocuments(files, id) { return function (dispatch) { const uploaders = _.map(files, f => { const formData = new FormData(); formData.append('file', f); return axios.post( `${URL}/api/${(id)}/documents/upload/success`, formData, { headers: { 'content-type': 'multipart/form-data', 'Authorization': 'JWT ' + sessionStorage.getItem('token') } } ) }); axios.all(uploaders) .then(response => { dispatch({ type: SUBMIT, payload: response[0].status }); }) } } The rejectedDocuments … -
bootstrap 4 modal open works on localhost with ng serve. But not on heroku with ng build django
All text as it is best to describe the problem this way. I have an angular 5 app. When I run the app locally by using ng serve a button I use to open a modal works.

I am using ng build not ng build -prod which I am trying now. the bootstrap is being imported by using the script imports on the index.html head files. What could be the issue. -
repr vs str in python classes - both are given
I have read and understood the difference between repr and str and noted the difference. repr - unambigous str - readable What happens is both is used? I wrote a simple class and found that repr is called when both are given. class test(): def __repr__(self): return 'repr called' def __str__(self): return 'str called' x = test() print x Now, when I check the implementation of both the classes in Django ValidationError, Im not sure when str will be called as the repr function is already overloaded. https://docs.djangoproject.com/en/2.0/_modules/django/core/exceptions/#ValidationError def __str__(self): # print 'validationerror str' if hasattr(self, 'error_dict'): return repr(dict(self)) return repr(list(self)) def __repr__(self): # print 'validationerror repr' return 'ValidationError(%s)' % self How and when the __str__ function will be called? -

Django javascript cannot be loaded after doing changes
Guys Currently, I am doing the Django website development Django version: 1.11.13 I added static folder in each app. and DEBUG = True in the settings.py the static files(javascript and css) can be found, but when I changed/added content in css, it can be reloaded. but the javascript cannot. what I did are: <script src="{% static 'assets/js/dashboard.js' %}?{% cache_bust %}" type="text/javascript"></script> cache_bust is templatetags which will add uuid at the end of js link. it does not work for the reloading of javascript in the browser.

Can't save related objects in django models using pre_save signal
I have to implement multi-aspect type of inheritance from UML in Django ORM. I have Contract data type which depending on type of customer (regular or business customer) can be classified as RegularContract or BusinessContract. Also contract can have expiration date or be non-expirable (it is not specified how long it will be valid), so it also can be of type ExpiringContract or NonExpiringContract. This is how concept diagram looks: And this is how I've implemented this: models.py code: class Contract(models.Model): approval_date = models.DateTimeField(null=False) def __getattr__(self, item): if self.expiringcontract: return getattr(self.expiringcontract, item) elif self.nonexpiringcontract: return getattr(self.nonexpiringcontract, item) class ContractExpirationExtension(models.Model): base = models.OneToOneField("website.Contract", on_delete=models.CASCADE) class Meta: abstract = True class ExpiringContract(ContractExpirationExtension): termination_date = models.DateTimeField() @property def duration(self): return self.termination_date - self.base.approval_date class NonExpiringContract(ContractExpirationExtension): @property def duration(self): return timedelta(days=100) class ContractTypeExtension(models.Model): base = models.OneToOneField("website.Contract", on_delete=models.CASCADE) termination_delay = models.PositiveSmallIntegerField(default=30) class Meta: abstract = True @classmethod def create(cls, approval_date, contract_expiration_type, termination_delay, **kwargs): type_extension = cls(termination_delay=termination_delay) base = Contract(approval_date=approval_date) expiration_type = contract_expiration_type(**kwargs) expiration_type.base = base type_extension.base = base if contract_expiration_type.__name__ == ExpiringContract.__name__: type_extension.base.expiringcontract = expiration_type elif contract_expiration_type.__name__ == NonExpiringContract.__name__: type_extension.base.nonexpiringcontract = expiration_type return type_extension def __getattr__(self, item): if self.base: return getattr(self.base,item) class RegularContract(ContractTypeExtension): termination_delay = models.PositiveSmallIntegerField(validators=[validate_term_delay_regular], blank=False) class BusinessContract(ContractTypeExtension): termination_delay = models.PositiveSmallIntegerField(validators=[validate_term_delay_business], blank=False) When we … -

Split Django queryset into a many sublists based on a given field
I have the following model: class Game(models.Model): users = models.ManyToManyField(User, through='Membership', related_name='users') date_game = models.DateField(default=datetime.date.today) class Membership(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, verbose_name=_('joueur')) game = models.ForeignKey(Game, on_delete=models.CASCADE) score = models.IntegerField(_('score'), default=0, validators=[ MaxValueValidator(50), MinValueValidator(0) ]) I also have this ListView, which aims at retrieving all the Membership object associated with a Game played by a given User: class GameListView(ListView): model = webapp_models.Membership template_name = 'list_games.html' form = webapp_forms.UserChoiceField def get_queryset(self): if self.request.method == 'GET': form = self.form(self.request.GET) if form.is_valid(): user = form.cleaned_data['user_choice_field'] # all games played by the user tmp = Game.objects.filter(membership__user=user) # all memberships associated to games played by the user out = Membership.objects.filter(game__in=tmp) for obj in out: print(obj.game.date_game, obj.game.id, obj.user.username, obj.score) return out return Membership.objects.all() def get_context_data(self, *args, object_list=None, **kwargs): context = super(GameListView, self).get_context_data(*args, object_list=None, **kwargs) # use the GET data to avoid resetting the form context['form'] = self.form(self.request.GET) return context I thus would like to split out (queryset of Membership) into sublists to gather all the Membership matching the same Game. Ideally, I would do this in the view rather than in the template. -

Error during template rendering: cache issue in django
I'm running django on my local machine for development, within a docker instance. However, frequently I run into errors of this kind: Error during template rendering "so-and-so" is not a valid view function or pattern name. This happens when I add a new line to my urls.py file, like so: path('test', views.test, name='test') If I then create a link using {% url 'app:test' %} then I will get the error mentioned above. However, the odd thing is that this is not a valid error. It only seems to appear due to some sort of a caching problem. I write the url name correctly, it's all in place, but the system acts as if the URL was not defined. When I restart Django, then it works just fine! Clearly I don't want to be restarting Django all the time. Any idea what could cause this? I have no special cache settings whatsoever in settings.py.
