How to write a unit test for uploading an Image in django rest framework
I'm using Django rest frame work to develop a RESTful API. I've implemented a post method that allows a user to upload and image as shown below. I'm using models.ImageField for the document field. Further below I have also implemented the test case I doubt it will work. How do I implement a test case for uploading and image. Post method def post(self, request, *args, **kwargs): """ Creates a document. """ logged_in_user = request.auth['user_id'] # print(request.data) org_id = get_auth(request) name = request.data['name'] document = request.FILES['document'] try: doc_object = Document.objects.create( owner = logged_in_user, org_id= org_id, name=name, document=document ) return Response(status=status.HTTP_201_CREATED) except Exception as e: raise e Test Case def test_can_upload_a_document(self): pic = os.path.join(settings.BASE_DIR, '/media/images/', 'test_pic.png') test_picture = open(pic, 'rb') payload ={ "owner":self.employee.id, "name":"Edward Gates", "document":test_picture, "notes":"Add notes here", "assessment_status":"Pending" } url = reverse('hr:documents') self.client.credentials(HTTP_AUTHORIZATION=self.token) response = self.client.post(url,data=payload,format='mutipart') self.assertEqual(response.status_code, 200) -
Saving translated slug of django modeltranslation not working
I've been breaking my head over this for a day now. I use django-modeltranslation to translate blog-like posts. All works fine, except I also try to automatically translate the slugs from the title, based off of this article: https://raphaelbeck.wordpress.com/2011/04/16/how-to-translate-slug-with-django-modeltranslation/ Only the translated slug is not translated saved to the database. class Item(models.Model): category = models.ForeignKey( 'help.category', on_delete=models.PROTECT, related_name='categories') title = models.CharField(_('Titel'),max_length=255) description = RichTextField(_('Omschrijving')) slug = AutoSlugField(_('slug'), populate_from='title', overwrite=True) class Meta: verbose_name = _(u"Item") verbose_name_plural = _(u"Items") #automatically creating slugs for translations def save(self, *args, **kwargs): for lang_code, lang_verbose in settings.LANGUAGES: if hasattr(self, 'slug_%s' % lang_code) and hasattr(self, 'title_%s' % lang_code): setattr(self, 'slug_%s' % lang_code, slugify(getattr(self, 'title_%s' % lang_code, u""))) print(self.slug_nl) print(self.slug_en) print(self.slug_nl) print(self.slug_en) super().save(*args, **kwargs) def __str__(self): return str(self.title) I added some print funtions to see what actually happens. The console logs are as expected: dutch-slug None dutch-slug english-slug dutch-slug english-slug -> slug_en is translated correctly based on the title in the console, but in the database the dutch slugs are saved. Thanks in advance! Any ideas are greatly appreciated. -
Writing in memory zip file to django FileField
Im trying to read files from FileField, put them all to zip and save that zip to another FileField. Im trying to avoid using temp file but it seems that i might have to.

get_FIELD_display() does not display correct value
I have been trying to use get_name_display() in my API View but it does not display the text, just number. I have checked the documentation but it does not mention anything about it - it should be working. For instance, the folowing code prints 3 instead of 'GaussianNB'. Model class Algorithm(models.Model): ALGORITHM_NAME = ( (0, 'KNeighborsClassifier'), (1, 'LogisticRegression'), (2, 'LinearSVC'), (3, 'GaussianNB'), (4, 'DecisionTreeClassifier'), (5, 'RandomForestClassifier'), (6, 'GradientBoostingClassifier'), (7, 'MLPClassifier'), ) name = models.CharField(max_length=64, choices=ALGORITHM_NAME) parameters = JSONField() View class CalcUpdateView(UpdateAPIView): queryset = Calc.objects.all() serializer_class = CalcSerializer def perform_update(self, serializer): instance = serializer.save() algorithm = Algorithm.objects.get(pk=self.request.data['algorithm']) print(algorithm.get_name_display()) Thanks in advance for help! -

Django logging to wxpython window?
I'm writing a utility to start up a django server process that outputs its logs to a TextCtrl in a wxpython window. Unfortunately, a couple different approaches have led to weird issues where the operating system (OSX in this case) crashing the program with complaints about "Illegal Instruction" after a few successful log entries. I'm currently doing this by implementing a logging.Handler subclass that posts events to wx that contain the logging records to be shown in the window. Is there a better approach? Thanks! -

Django-filter best practice on model field choice filter
I am struggling with an issue that I would think is pretty common but on which i couldn't find any working example. Say I have a Django Model : class Shop(models.Model): name = models.CharField(max_length=100, verbose_name="Shop Name") ... city = models.CharField(max_length=100, verbose_name="City") ... class Meta: verbose_name = "Chantier" What would be the best way to allow the user to filter Shops by City using django-filter ? So far I've used ModelMultipleChoiceFilter with the widget CheckboxSelectMultiple, but for some reason I'm struggling with getting a clean list of choices (no duplicates) and linking the filtered values to an actual filter query that works (without having to do some complex things). Is there an easy way to do this ? Thanks ! -

Django Import Export Object of type Post is not JSON serializable
Hi all please bear with me if this is a trivial question as i am just starting off with Django. I am using Django-Import-Export to integrate import/export actions to the Django Admin interface. Every thing works fine after subclassing my admin class with ImportExportActionModelAdmin. However one of the fields in the model is a JSONField and it is exported as is (as expected). I want the keys in the JSON to be converted into separate fields when I export it. Sample Code: class Post(models.Model): title = models.CharField(max_length=50) content = models.TextField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) details = JSONField(null=True, blank=True, default=dict) objects = models.Manager() def __str__(self): return self.title class PostResource(resources.ModelResource): details = fields.Field(attribute='details', widget=JSONWidget) class Meta: model = Post fields = ('details',) class PostAdmin(ImportExportActionModelAdmin): resource_class = PostResource After doing this, when I try to export the data from the Admin interface it gives me the following error in the browser. Object of type Post is not JSON serializable Request Method: POST Request URL: http://127.0.0.1:8000/admin/post/post/ Django Version: 2.1.3 Exception Type: TypeError Exception Value: Object of type Post is not JSON serializable Thanks in advance -

Django Admin Interface - Privileges On Development Server
I have an old project running (Django 1.6.5, Python 2.7) live for several years. I have to make some changes and have set up a working development environment with all the right django and python requirements (packages, versions, etc.) Everything is running fine, except when I am trying to make changes inside the admin panel. I can log on fine and looking at the database (sqlite3) I see my user has superuser privileges. However django says "You have no permissions to change anything" and thus not even displaying any of the models registered for the admin interface. I am using the same database that is running on the live server. There I have no issues at all (Live server also running in development mode with DEBUG=True has no issues) -> I can see the history (Change Log) - Nothing else I have also tried to create a new superuser (which it does) but same problem here. I'd appreciate any pointers (Maybe how to debug this?) -

My js: $.post('http://127.0.0.1:8000/api/sessions/create/', { questions: JSON.stringify(questions) }) When I log JSON.stringify(questions) I see it's looking like it has to be: [{"description":"test5","type":"YESNO","to_close":5,"choices":""},{"description":"test5","type":"YESNO","to_close":5,"choices":""}] I can even copy and paste it to curl, and it will work: curl -X POST http://127.0.0.1:8000/api/sessions/create/ -H 'Content-Type: application/json' --data '{"questions":[{"description":"test4","type":"YESNO","to_close":5,"choices":""},{"description":"test3","type":"YESNO","to_close":5,"choices":""}]}' But when I do via JS, Django receives it this way: <QueryDict: {'questions': ['[{"description":"test5","type":"YESNO","to_close":5,"choices":""},{"description":"test7","type":"YESNO","to_close":5,"choices":""}]']}> My post method looks like this: def post(self, request, **kwargs): """Create a session of questions""" question_data = request.data.pop('questions') session = QuestionSession.objects.create() for question in question_data: Question.objects.create( description=question['description'], question_type=question['type'], answers_to_close=question['to_close'], question_session=session) serializer = QuestionSessionSerializer(data=request.data, many=True) serializer.is_valid() serializer.save() return Response({ 'status': 'SUCCESS', 'message': 'A new session has been created!' }) What is wrong? Since I can easily do it via curl, I think the problem is in jquery request. -

Can soneone give me an Idea for authentication an Django Company Application via AD / SSO
Right now i'm developing an company application based on django. For authentication and authorization right now i use django-auth-ldap. But i will add a SSO feature, so my guys working in the company don't need to login if they are working on an company computer. For authorization purpose i use the group mechanism from django-auth-ldap, but django-auth-ldap don't support sso on my web application. Has anyone an Idea for: Company application, User base is Microsoft Active Directory right managemend should be done via AD-groups django-auth-ldap is working, bug users has to login in the application working on an company computer (running kerberos) should auto-login to the web-application rights managemend should work using django-auth-ldap Thanks a lot for an idea to let this run.
