allowedhosts=[] using Django and Apache2
I have a Django project and I am using Apache2. My settings.py file looks like this: DEBUG = False ALLOWED_HOSTS = ['localhost', '165.232.125.35', '.meesuis.org', 'www.meesuis.org'] When I type the 165.232.125.35 the site comes up fine. But when I type the actual website name it doesn't work. Can someone please confirm that I have the settings.py file set up correctly so that I will know for sure the problem is somewhere else? Thank you. -
Reverse for 'update_task' with arguments '('',)' not found. 1 pattern(s) tried: ['update/(?P<update>[^/]+)/$']
I am building a small CRUD project and stuck on a very basic thing which is an update.

Django projects fail on Ubuntu 20.04
I just upgraded Ubuntu from 18.04 to 20.04, and ALL my Django projects (tens of them) were not working. One of the problem related to psycopg2 when executing pip: For example, there is "psycopg2==2.7.3.1" in my "requirements.txt" file, and running "pip install -r requirements.txt" resulted in errors when building wheel for psycopg2. Change "psycopg2==2.7.3.1" to ""psycopg2-binary" solved the problem. So, is such change necessary for all projects running on Ubuntu 20.04? Other error examples from various projects when running server: RuntimeError: __class__ not set defining 'AbstractBaseUser' as <class 'django.contrib.auth.base_user.AbstractBaseUser'>. Was __classcell__ propagated to type.__new__? SyntaxError: Generator expression must be parenthesized (widgets.py, line 151) AssertionError: SRE module mismatch ModuleNotFoundError: No module named 'decimal' ... etc. How to I fix these problems? I've been in a headache for weeks. -
How to customize response message in ModelViewSet
I will send the request in post format using ModelViewSet and I will customize its response message. So I turned the response back on the perform_create method as shown in the following code, but it doesn't work as I want. class CreateReadPostView (ModelViewSet) : serializer_class = PostSerializer permission_classes = [IsAuthenticated] queryset = Post.objects.all() pagination_class = LargeResultsSetPagination def perform_create (self, serializer) : serializer.save(author=self.request.user) return Response({'success': '게시물이 저장 되었습니다.'}, status=201) # it's not work How can I make this work normally? Thank in advance. -
Is there easier way to use bulk_create() with many query to instance create items
I don't have basic programming at all and just learned python and Django a few months ago, due to an urgent need I decided to create my own program to support my department and team After the program is running, I want to make it easier for the user and after I look around it is recommended to use bulk_create and ajax JavaScript, definitely not using JavaScript. After looking for ways to use bulk_create, I find it inefficient like: instance = get_object_or_404(Audit, id=766) item1 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=1) item2 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=2) item3 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=3) item4 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=4) item5 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=5) item6 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=6) item7 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=7) item8 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=8) item9 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=9) item10 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=10) item11 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=11) item12 = get_object_or_404(Item.objects.filter(aspek=instance.aspek_audit).filter(active=True),id=12) audit_mie = [ AuditItem(audit=instance,item=item1,kategori=item1.kategori.kategori), AuditItem(audit=instance,item=item2,kategori=item2.kategori.kategori), AuditItem(audit=instance,item=item3,kategori=item3.kategori.kategori), AuditItem(audit=instance,item=item4,kategori=item4.kategori.kategori), AuditItem(audit=instance,item=item5,kategori=item5.kategori.kategori), AuditItem(audit=instance,item=item6,kategori=item6.kategori.kategori), AuditItem(audit=instance,item=item7,kategori=item7.kategori.kategori), AuditItem(audit=instance,item=item8,kategori=item8.kategori.kategori), AuditItem(audit=instance,item=item9,kategori=item9.kategori.kategori), AuditItem(audit=instance,item=item10,kategori=item10.kategori.kategori), AuditItem(audit=instance,item=item11,kategori=item11.kategori.kategori), AuditItem(audit=instance,item=item12,kategori=item12.kategori.kategori), ] AuditItem.objects.bulk_create(audit_mie) is there an easier way besides the method above? if not, then I stick with it, by creating objects in each item id which is approximately 130 (currently) and I will group it into 8 (currently) bulk_create() method. I am stuck here, if anyone can help this to make it easier, I am very, very Thank you -
Recommendations for possible feed algorithms?
I am currently tasked with creating an algorithm that delivers a continuous flow of posts to the end user via an endless scrolling mechanism. There are some obvious answers (e.i. display posts via date created and show them chronologically). However, this has some major drawbacks (e.i. depending on the timezone, some posts will get burried while others get all the attention arbitrarily). What are some alternative ways (with coding examples) to implement an algorithmic feed? Any resources/blog posts would be greatly appreciated. -
ModelAdmin - how to inline model to another model view using intermediate relation table using foreign key
I want to make able to edit (add or delete) film work persons (actors, writers, director). I have the following models: class FilmWork(models.Model): id = models.UUIDField(primary_key=True, db_column='id', default=uuid.uuid4) title = models.CharField(_('название'), max_length=255) class Meta: db_table = 'film_work' managed = False class Person(models.Model): id = models.UUIDField(primary_key=True, db_column='id', default=uuid.uuid4) full_name = models.TextField(_('полное имя'), max_length=255) class Meta: db_table = 'person' managed = False class FilmWorkPerson(models.Model): id = models.UUIDField(primary_key=True, db_column='id', default=uuid.uuid4) film_work = models.ForeignKey(FilmWork, models.DO_NOTHING, blank=True, null=True, related_name='film_work_person') person = models.ForeignKey(Person, models.DO_NOTHING, blank=True, null=True, related_name='person') role = models.CharField(_('роль'), max_length=50, choices=PersonRole.choices) class Meta: db_table = 'film_work_person' unique_together = (('film_work', 'person', 'role'),) managed = False Now I don't know how to show 'full_name' and 'role' fields on the FilmWorkAdmin(admin.ModelAdmin) - I found that Inline could help, but since I have intermediate table FilmWorkPerson which has ForeignKey field pointing to FilmWork, I can display 'role', but 'full_name' seems unaccessible in any way. Since it is not ManyToMany but ForeignKey I can not use 'through' I can't use fields lookup like 'person__full_name' since it is available in QuerySets filters only(?) I can not directly inline Person from FilmWorkAdmin since there are no direct connection between FilmWork and Person (did I miss some reverse lookup tool?) I don't believe … -

How can I serve a stand-alone static app through Django
We're using django for authentication, user management, site content etc, but we have a JS tool that needs to be behind django auth as well. The tool is an html page that pulls in a couple dozen static files through relative paths in the html page (src="./someJSfile.js"). The problem is I can't figure out how to serve the html file through django but keep the relative paths intact. I can create an apache alias to that directory so that the relative paths are intact, but then the html is served through apache and bypasses auth. I would like to be able to have the html file served through a django view so that auth works, and also keep the static files in the same directory. Is there some apache magic where I can have the html served through django but have the static served through apache using an alias, while keeping the html and static in the same directory? Thanks in advance -

Persistent "[Errno 61] Connection refused" error in Django

Deploy Web Application Nuxtjs/Django/PostgreSQL
Right now I'm developing a website base on Nuxt as the Frontend and Django as the backend with a PostgreSQL database, I'm a little new to this field but I'm not sure how exactly to deploy and host my app, I've been looking at AWS Services to do it, like using Lightsail or just deploy everything on an ES2 instance to save money instead of deploying each element on a different server, the problem with the last option is that it wont be able to scale, in case in the future the visits to the site increase. I really appreciate some recommendation or orientation about how I could do it this easy, cheap and scalable. -
How to pass multi optional URL parameters in django?
How to pass multi optional URL parameters? For example I want pass 2 params: my_color and my_year, but they are optional, so may be none of them will be passed, may be both, or may be only one. Currently in urls.py I have : urlpatterns = [ re_path(r'^products/(?P<my_color>.*)/(?P<my_year>.*)$', some_view), ] This obviously is not correct and works only if both of them are passed. What would be correct solution? P.S. I found answers when only one optional parameter needs to be pass, but not figured out how to do same for few parameters. Also it seems "multiple-routes option" is not solution in this case ? -
Passing data from Django views to vue instance as JSON object
I have the following Django view method, being used to send information over to some Vue.js frontend code in details.html. I am basically wondering how do I send over the data to the vue template. How do I do JSON dumps? I think that is what I am messing up here. def works(request): heading_info = Heading.objects.order_by('-name')[:1] welcome_info = Welcome.objects.order_by('-title')[:1] skills_info = Skill.objects.order_by('position')[:5] projects_info = Project.objects.order_by('name')[:10] items = [] items.append({'heading_info':heading_info, 'welcome_info':welcome_info, 'path':path, 'path2':path2, 'skills_info':skills_info,'projects_info':projects_info}) # context = {} # context["items_json"] = json.dumps(items) context = {'heading_info':heading_info, 'welcome_info':welcome_info, 'path':path, 'path2':path2, 'skills_info':skills_info,'projects_info':projects_info} return render(request, 'home/details.html', context) And here is my html where I am trying to access this data. <script type='text/javascript'> var data = {{ projects_info|safe }}; </script> <div id="app"> [[projects_info_vue]] {% comment %} #Passing array as vue data.

In django serializer response, how to get rid of absolute path (media_url prefix) for FileField?
I have used a models.FileField() in my model and I have created a simple ModelSerializer and CreateAPIView for it. As I am using AWS S3, when posting a file, I receive Json response that includes MEDIA_URL as prefix of filename i.e.: { "id": 32, "file": "https://bucket.digitaloceanspaces.com/products/capture_a50407758a6e.png" } What i would like to achieve instead is to either keep only a file name: { "id": 32, "file": "capture_a50407758a6e.png" } or to be able to change the prefix to some other: { "id": 32, "file": "https://google.com/capture_a50407758a6e.png" } The change should only be visible in Json response and and the database entry. The S3 details should be still sourced as they are from settings.py. Hope it makes sense. Let me know if anyone has any idea as I'm only able to find solution for providing full/absolute path.

How to add images to individual model boxes?
So the problem am trying solve is how can I add images to separate model boxes? For example if I were to press on the Toyota Tacoma I would only see pictures of Toyota Tacoma and if I pressed on the Ford F-150 I would only see pictures of the Ford F-150.

Please share any idea in which direction to go. -

All of them are one to one relations. Here is my user serializer: class UserSerializer(serializers.HyperlinkedModelSerializer): profile = UserProfileSerializer(required=True) garden = GardenSerializer(read_only=True) gardener_profile = GardenerProfileSerializer(read_only=True) class Meta: model = CustomUser fields = ['id', 'url', 'username', 'email', 'first_name', 'last_name', 'password', 'groups', 'profile', 'garden', 'gardener_profile'] extra_kwargs = {'password': {'write_only': True}} And here are the models: class CustomUser(AbstractUser): email = models.EmailField(unique=True) class UserProfile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='profile') address = models.CharField(max_length=255) country = models.CharField(max_length=50) city = models.CharField(max_length=50) zip = models.CharField(max_length=5) class Garden(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) grass = models.DecimalField(max_digits=6, decimal_places=2) terrace = models.DecimalField(max_digits=6, decimal_places=2) class GardenerProfile(models.Model): user = models.OneToOneField(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) salary = models.DecimalField(max_digits=6, decimal_places=2) contract = models.FileField(null=True, blank=True) class WorkingHours(models.Model): gardener_profile = models.ForeignKey(GardenerProfile, related_name='working_hours', on_delete=models.CASCADE) weekday = models.IntegerField(choices=WEEKDAYS) from_hour = models.TimeField() to_hour = models.TimeField() class Meta: ordering = ('weekday', 'from_hour') unique_together = ('weekday', 'gardener_profile') -
