ForeignKey relationship on two fields which are unique together
I'd like to make a relationship like so in django: class ColorModel(models.Model): article = models.ForeignKey(ArticleModel, to_field='name', on_delete=models.CASCADE) color = models.CharField(max_length=10) class Meta: unique_together = ('article', 'color') class TaillesModel(models.Model): article = models.ForeignKey(ColorModel, on_delete=models.CASCADE) color = models.ForeignKey(ColorModel, on_delete=models.CASCADE) size = models.CharField(max_length=10) quantity = models.IntegerField() So each article has multiple colors, and each of those colors has multiple sizes in different quantities. However, this gives me those errors: Reverse accessor for 'TaillesModel.article' clashes with reverse accessor for 'TaillesModel.color'. HINT: Add or change a related_name argument to the definition for 'TaillesModel.article' or 'TaillesModel.color'. front.TaillesModel.color: (fields.E304) Reverse accessor for 'TaillesModel.color' clashes with reverse accessor for 'TaillesModel.article'. HINT: Add or change a related_name argument to the definition for 'TaillesModel.color' or 'TaillesModel.article'. I don't understand what related_name is supposed to be set to here. Thanks in advance for your help. -
Trouble Uploading files with Django Rest Framework GenericViewSet class
I know there are lots of questions with answers about uploading files with Django but none of the ones I have read have helped me. Many answers say I need to get my uploaded files from request.FILES but I have seen answers saying that's deprecated. Django Rest Framework 3: Uploading files without request.FILES. Anyways here is my code: My model: class DamagePhoto(models.Model): ... omitted for brevity ... damage = models.ForeignKey(Damage, related_name='photos', on_delete=models.CASCADE) photo = models.ImageField(max_length=256, upload_to=get_image_path, blank=True, null=True) side = models.CharField(max_length=16, choices=choices) My view: class VehicleDamagePhotoViewSet(mixins.ListModelMixin, mixins.CreateModelMixin, mixins.RetrieveModelMixin, mixins.UpdateModelMixin, mixins.DestroyModelMixin, viewsets.GenericViewSet): serializer_class = DamagePhotoSerializer queryset = DamagePhoto.objects.all() lookup_field = 'uid' lookup_url_kwarg = 'uid' lookup_value_regex = '[0-9a-f-]{36}' ordering_fields = ['modified', ] ordering = ['modified'] def get_serializer_context(self): print(f"get_serializer_context() called. request.FILES is {self.request.FILES}.") return {'request': self.request} def get_damage(self, damage_uid): return Damage.objects.get(uid=damage_uid) def get_queryset(self): return self.queryset.filter(damage__uid=self.kwargs['damage_uid']) def perform_create(self, serializer): print(f"preform_create() called request.FILES is {self.request.FILES}.") return serializer.save(damage=self.get_damage(self.kwargs['damage_uid'])) The serializer: class DamagePhotoSerializer(serializers.ModelSerializer): @transaction.atomic def create(self, validated_data, *args, **kwargs): request = self.context['request'] print(f"serializer create request.FILES is {request.FILES}.") return super(DamagePhotoSerializer, self).create(validated_data=validated_data, *args, **kwargs) class Meta: model = DamagePhoto fields = ('__all__') The part of my unit test that fails: url = reverse("vehicle:damagephoto-list", kwargs={'damage_uid': new_damage.uid}) image_path_1 = '/Users/red/myproject/test_data/photos/test_image.jpg' file_ob = {'photo': ('test_image.jpg', open(image_path_1, "rb"))} data = { 'file': file_ob, … -
Django as backend for React native mobile app, How can we authenticate users with social media signup?
Using Django Rest framework we can support mobile apps, for websites Django can authenticate users based on social media using Allauth library. When user signup with Facebook ,a new tab opens and authenticate user with permission. How can we do this for mobile apps ? I think Standard packages like AllAuth wont support it. I do not need the codes, but any guidance will be useful -
How can I update multiple models using Django's class based views?
I have seen similar questions but the question was not explained in a way that explains my current scene. I have this in my models.py: class CustomUser(AbstractUser): USER_TYPE = ((1, 'HOD'), (2, 'Staff'), (3, 'Student')) user_type = models.CharField(default=1, choices=USER_TYPE, max_length=1) class Student(models.Model): course = models.ForeignKey( Course, on_delete=models.DO_NOTHING, null=True, blank=False) admin = models.OneToOneField(CustomUser, on_delete=models.CASCADE) gender = models.CharField(max_length=1, choices=GENDER) address = models.TextField() profile_pic = models.ImageField(upload_to='media') session_start_year = models.DateField(null=True) session_end_year = models.DateField(null=True) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now_add=True) In my forms.py, I have this: class StudentForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(StudentForm, self).__init__(*args, **kwargs) for visible in self.visible_fields(): visible.field.widget.attrs['class'] = 'form-control' class Meta: model = Student fields = ['course', 'gender', 'address', 'profile_pic', 'session_start_year', 'session_end_year'] widgets = { 'session_start_year': DateInput(attrs={'type': 'date'}), 'session_end_year': DateInput(attrs={'type': 'date'}), } class CustomUserForm(forms.ModelForm): email = forms.EmailField(required=True) first_name = forms.CharField(required=True) last_name = forms.CharField(required=True) password = forms.CharField(widget=forms.PasswordInput) widget = { 'password': forms.PasswordInput() } def __init__(self, *args, **kwargs): super(CustomUserForm, self).__init__(*args, **kwargs) for visible in self.visible_fields(): visible.field.widget.attrs['class'] = 'form-control' def clean_email(self): if CustomUser.objects.filter(email=self.cleaned_data['email']).exists(): raise forms.ValidationError("The email is already registered") return self.cleaned_data['email'] class Meta: model = CustomUser fields = ('first_name', 'last_name', 'email', 'username', 'password', ) help_texts = {'username': None} I created a form using this context: context = {form': [CustomUserForm(), StudentForm()]} Now, I am trying to … -

Django Flatpage Catchall URLConf and Name for `url` Templatetag
I've gone back and forth between these two flatpage URL patterns: urlpatterns += [ # path('about', views.flatpage, {'url': '/about'}, name='about'), re_path(r'^(?P<url>.*)$', views.flatpage), ] When using the explicit path, I can use the name in my templates like so: <a href="{% url 'about' %}">About</a> But when using the catchall, I can't figure out whether this is possible. I've got quite a few flatpages (maybe a dozen or more, and I'll likely add more later), so having the catchall is an attractive option. However, I really like being able to use the url templatetag. Can I get the best of both worlds? -
Restart Apache in Lightsail Terminal
As I found a blocker in one approach to make a Django app production ready I've gone with a different approach documented here. In particular, this question is about this step where it says «Restart Apache for the changes to be taken into effect» and has the following associated command sudo /opt/bitnami/ctlscript.sh restart apache Thing is, ctlscript.sh isn't in that folder but in /opt/bitnami/stack. Then, when running in that forder sudo ctlscript.sh restart apache I get this error sudo: ctlscript.sh: command not found The file is there so I thought it would be something related with permissions (as pointed here). So, ran The script is in the right folder, so the problem points to incorrect permissions. sudo chmod 755 ctlscript.sh but running the command to restart Apache got me into the same "command not found" error. -
Django do not reload fixture for some test cases
For every test class I generated base .json fixture with data. It is pretty clear and fast way, because I do not need to spent time to generate data. Any additional data I can generate with factories directly in test. class ProfileViewTests(MyProjectTestCase): fixtures = [os.path.join('compiled', 'test_companies_and_users.json')] def test1(self): pass def test2(self): pass The issue that the loading of some fixtures is takes up to 15 sec., because they creating a huge piece of test data environment. And now 70% of time I'm wasting to loading fixtures after every test case. The upside is because when we update objects we do not need care about flushing this data, but downside that time is increasing with every test. I can move some data to setUpTestData, but revisit all this data for all this tests is almost impossible. My question is there a decorator to say some tests cases do not reload fixtures, if they not modify data. @do_not_flush_data_from_database_for_next_test_case_from_this_class def get_users_test(self): pass Or any other way to speed up this -
Django user authentication not working on every subpage
i have strange (and probable simple) problem with user authentication in Django. I added to base.html file this code: {% if user.is_authenticated %} <p>{{user.get_username}} is logged in</p> <a href="{% url 'logout' %}">logout</a> {% else %} <p>You are not logged in!</p> <a href="{% url 'login' %}">login</a></a> {% endif %} Then i added this line to every other template: {% extends "base.html" %} It looks good because every subpage display this lines of code, unfortunately sometimes is displaying code when user is authenticated and sometimes where he is not authenticated.For example when i switch between two subpages once i get information that user with his login is logged, on this second webpage i get information that i am not logged in and when i come back to that first subpage i am again authenticated... How could i change it? What could be a problem? my views about login: def login_user(request): login_user = {} login_user.update(csrf(request)) return render_to_response('login.html', login) def auth_view(request): username = request.POST.get('username', '') password = request.POST.get('password', '') user = auth.authenticate(username=username, password=password) if user is not None and user.is_active: auth.login(request, user) return redirect('loggedin') else: return HttpResponseRedirect('invalidlogin') def logged_in(request): return render_to_response('loggedin.html', {'user': request.user}) and my 'login' urls: path('login', views.login, name='login'), path('authorized', views.auth_view, name='authorized'), path('loggedout', … -

migrate django model primary key UUID field to CharField
I need to change the id field size on an oracle database to support storing longer id's. By default using the UUIDField in django creates a table with varchar field of 32 bytes but we now need it to store ids generated by uuid.uui4 and of supplied id's of character lengths up to 80. What is the least hacky way to do this in django so that the migrations are consistent across environments while keeping foreign key relationships in other models? class CurrentModel(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) class desiredModel(models.Model): id = models.CharField(max_length=80, primary_key=True, default=uuid.uuid4) -

Wagtail V2 API force HTTPS for the html_url and detail_url
I am currently developing a portfolio website that has a Django + Wagtail backend to manage the content in a React frontend that talks to each other through Wagtail V2 API and Django-Rest-Framework. I am currently running into an issue where I am able to get the pages from the API, but when my frontend tries to load individual page details the Wagtail v2 API is sending the detail_url as a http url where my nginx setup requires https. I have looked all over the wagtail documentation and stackoverflow for the answer to forcing the detail_url to be a https url but I cannot find the answer or documentation anywhere, nor do I know where to start. What part is causing the http? Is it Django, Wagtail or Rest-Framework? And how do I get it to be https This is what my JSON code looks like from the backend { "meta": { "total_count": 2 }, "items": [ { "id": 3, "meta": { "type": "pages.HomePage", "detail_url": "http://dylan.primic.com/api/v2/pages/3/", "html_url": "http://dylan.primic.com/", "slug": "home", "first_published_at": "2020-09-29T14:58:50.272668Z" }, "title": "Home" }, { "id": 4, "meta": { "type": "pages.AboutPage", "detail_url": "http://dylan.primic.com/api/v2/pages/4/", "html_url": "http://dylan.primic.com/about-me/", "slug": "about-me", "first_published_at": "2020-09-29T15:00:10.624868Z" }, "title": "About Me" } ]} Any help will … -

I'm having a problem on sending a ManyToManyField from a model to a dictionary using the model_to_dict() Below is my code models.py from django.db import models from django.forms import model_to_dict from app_1.models import * class Stuff(models.Model): thing_1 = models.CharField(max_length=100, null=True, blank=True) thing_2 = models.ManyToManyField(OtherStuff, blank=True, related_name="thing") def toJSON(self): item = model_to_dict(self) item['thing'] = self.thing.toJSON() return item When I run a query and load my Stuff model, I get the following error: from app_2.models import * s = Stuff.objects.get(pk=1) # here is where I send my model to a dictionary s.toJSON() Traceback (most recent call last): File "<input>", line 1, in <module> File "P:\test\app\app_2\stuff\models.py", line 10, in toJSON return item AttributeError: 'ManyRelatedManager' object has no attribute 'toJSON' I've come across multiple ways of sending a ManyToManyField to a dictionary, however, none of them use the model_to_dict(). I'd like to use this method due to it's simplicity of usage. -
page is loading very slow
Hi there I have a page and it is loading very slow. I had a very similiar question but this time I guess it requires another solution. I use django for my website and it has some jquerry in the template however I guess that the issue can be on the views. I will post my views and if it is neccessary my templates. Thank you in advance. views.py from django.shortcuts import render import openpyxl def index(request): wb=openpyxl.load_workbook('ders.xlsx') ws=wb.active context_lectures=[] context_lecture=[] context_select=[] for i in range(ws.max_row): day=ws.cell(row=i+1,column=6).value a=0 for j in range(len(day)): if day[j].isupper() and j!=0 and a!=j: day=day[:j]+' - '+day[j:] a=j+3 hour=ws.cell(row=i+1,column=7).value b=0 for k in range(len(hour)): if k%9==0 and k!=0: hour=hour[:k+b]+' - '+hour[k+b:] b+=3 lectures=ws.cell(row=i+1,column=2).value[:4] lecture=ws.cell(row=i+1,column=2).value select=ws.cell(row=i+1,column=1).value+' | '+ws.cell(row=i+1,column=2).value+' | '+ws.cell(row=i+1,column=3).value+' | '+ws.cell(row=i+1,column=4).value+' | '+day+' | '+hour if lectures in context_lectures: pass else: context_lectures.append(lectures) if lecture in context_lecture: pass else: context_lecture.append(lecture) if select in context_select: pass else: context_select.append(select) return render(request,'index.html',{'context_lectures': context_lectures,'context_lecture':context_lecture,'context_select':context_select}) and I would also ask where should I deploy my xlsx file. I didn't found a solution so I deployed it on the main project folder where manage.py is. -
Twilio with Django
I am trying to use Twilio with Django. I have followed this tutorial and it works properly. I am now trying to apply that within my own project. I've taken a copy of package.json into my project's root directory and I've run npm install to set up the node_modules directory. I have also copied the get_token and call views as is. Something is going wrong in the JS because I can see the get_token call but not the call call (if you know what I mean). My call button is an exact copy of the example project and when I click it I get the following error: Received an error from MediaStream: Object { info: {…} } twilio.min.js:99:91242 error http://127.0.0.1:8000/static/twilio.min.js:99 onerror http://127.0.0.1:8000/static/twilio.min.js:99 _initializeMediaStream http://127.0.0.1:8000/static/twilio.min.js:99 makeOutgoingCall http://127.0.0.1:8000/static/twilio.min.js:99 connect http://127.0.0.1:8000/static/twilio.min.js:99 accept http://127.0.0.1:8000/static/twilio.min.js:99 (Async: promise callback) accept http://127.0.0.1:8000/static/twilio.min.js:99 connect http://127.0.0.1:8000/static/twilio.min.js:99 callCustomer http://127.0.0.1:8000/static/prospecting/js/browser-calls.js:106 onclick http://127.0.0.1:8000/?page=3:1 My Twilio settings have been checked, double checked and triple checked. I believe them to be correct. -
