How to fix 500 Internal Server Error in Django application?
I want to deploy a Django application but I have got an 500 Internal Server Error.

Custom save method in model form
I have a discussion about this code. I think it works, but someone else says it doesn't work. Actually I can't test it but I don't understand why this should not work. The discussion: Person A: "I'm not sure what your question is, but your custom save logic will never be called, because you always pass commit=False" Me: "I think this should work or did i misunderstood something? Because after t = transaction_profile.save(commit=False) he is calling t.save() and the save() method has commit=True as a default value" Person A: "No. Look at what your save method returns: obj, which is an instance of the model. So t.save() calls the model save, not the form one." views.py def checkout_page(request): session_order_id = request.session['order_id'] if request.POST: transaction_profile = TransactionProfileModelForm(request, request.POST) if transaction_profile.is_valid(): t = transaction_profile.save(commit=False) t.save() else: transaction_profile = TransactionProfileModelForm(request) forms.py from orders.models import Order class TransactionProfileModelForm(forms.ModelForm): email_confirm = forms.EmailField() class Meta: model=TransactionProfile fields = [ 'email', 'email_confirm', 'address_line_1', 'address_line_2', 'city', 'country', 'postal_code', 'state' ] def __init__(self, request, *args, **kwargs): self.request = request super(TransactionProfileModelForm, self).__init__(*args, **kwargs) def save(self, commit=True): obj = super(TransactionProfileModelForm, self).save(commit=False) if commit: obj.save() request = self.request session_order_id = request.session['order_id'] o = Order.objects.get(order_id=session_order_id) o.transaction_profile = obj o.save() return obj -
how to get field type in forms.py (not in template) Django
I want to get a specific field type in the forms.py, so I can add to that fields group a specific CSS class. In my models.py I have multiple CharField, DateField and others like BigIntegerField, etc., and I want to ask for that. Here's my code: forms.py class MyForm(forms.ModelForm): def __init__(self, *args, **kwargs): super(MyForm, self).__init__(*args, **kwargs) for field in self.fields: if type(field) == CharField: #Here's the problem self.fields[field].widget.attrs.update({ 'class': 'form-control'}) class Meta: model = MyModel fields = '__all__' I can't do it one by one because I have many fields in my model. Any ideas how can I do that? Thanks a lot. -
Add Font Awesome icon with label_tag
How do I add a Font Awesome icon like <i class="fa fa-calendar"></i> to the following {{form.date.label_tag}} which uses widget_tweaks? I know generally you'd just do it like this <h2><span>Add<i class="fa fa-plus"></i></span></h2> but I haven't had any luck. -
iterating over a queryset and replacing foreign keys with their related objects django rest framework
I have the following models: class STUser(AbstractBaseUser): email = models.EmailField(unique=True) name = models.CharField(max_length=255) ... class VenuePermissions(models.Model): user = models.ForeignKey(STUser, on_delete=models.CASCADE) venue = models.ForeignKey(Venue, on_delete=models.CASCADE, blank=True, null=True) ... class Venue(models.Model): name = models.CharField(max_length=100) description = models.CharField(max_length=1500, null=True, blank=True) ... I am then prefetching the related venuepermission objects to a STUser object in a view class VenueUserList(APIView): def get(self, request, *args, **kwargs): objects = STUser.objects.prefetch_related('venuepermissions_set').all() ... Then I want to take the returned query set and replace the venue FKs with their objects. for item in objects: for permission in item_venuepermissions_set: permission_venue = Venue.objects.get(pk=permission_venue) print(repr(objects)) ... return Response({}) but my approach is clearly wrong. how do I properly access a field of a queryset and change its value? As you can see I need to do it twice. Once to access the current objects permission_set and again to access that permission_set venue field and override it. I do not want any of this changing the database. This is just to return the values. -
How to sum only selected rows from a list

Django makemigrations gives exception after I changed the type of a field to a custom type
I had something like this class modelEmployee(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True) employee_image = models.ImageField(upload_to='images/',null=True,blank=True,default='images/') Then I replaced the employee_image with this type instead class modelEmployee(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, null=True, blank=True) employee_image = Base64Field() I got the Base64Field from here.Thats what it looks like class Base64Field(models.TextField): def contribute_to_class(self, cls, name): if self.db_column is None: self.db_column = name self.field_name = name + '_base64' super(Base64Field, self).contribute_to_class(cls, self.field_name) setattr(cls, name, property(self.get_data, self.set_data)) def get_data(self, obj): return base64.decodestring(getattr(obj, self.field_name)) def set_data(self, obj, data): setattr(obj, self.field_name, base64.encodestring(data)) However after changing the type and running makemigrations. I get the error Traceback (most recent call last): File "/Users/admin/Development/foo/virtual/lib/python3.5/site-packages/django/db/models/options.py", line 566, in get_field return self.fields_map[field_name] KeyError: 'employee_image_base64' Any suggestions on how I can fix this ? -
Sessions Django: Daphne + Uwgsi
I am currently deploying a django project using channel 2.x with uwgsi for http requests and daphne for background tasks. Daphne by itself is running correctly as well as uwgsi. Configuration for both is the following: location /stream { # daphne server running on port 8001 so we set a proxy to that url proxy_pass http://0.0.0.0:8001; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Host $server_name; } # These requests are handled by uwsgi location / { include uwsgi_params; uwsgi_pass unix:/run/uwsgi/app/project/socket; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # Make the following two variables accessible to the application: uwsgi_param SSL_CLIENT_VERIFY $ssl_client_verify; uwsgi_param SSL_CLIENT_RAW_CERT $ssl_client_raw_cert; } All background workers are preceded by /stream. All endpoints server via / and /stream are protected. When login in and accesing endpoints such as /api/v1/resource it correctly returns the data but when triggering tasks via /stream I get permission denied (403). Debugging this behavior I have come to the conclusion that sessions are not persisted among Daphne and Uwsgi. How can I achieve sessions to be shared between them? -
Group by select related objects django, django rest framework
I have the following models: class STUser(AbstractBaseUser): email = models.EmailField(unique=True) name = models.CharField(max_length=255) companyname = models.CharField(max_length=200, blank=True, null=True) ... class VenuePermissions(models.Model): user = models.ForeignKey(STUser, on_delete=models.CASCADE) venue = models.ForeignKey(Venue, on_delete=models.CASCADE) signupvaildatestring = models.CharField(max_length=200, blank=True, null=True) ... And I wanted to create a query that gets all the venuepermissions but instead of a user pk and a venue pk it returns the user and venue objects. here is the view and serializer I am using a generic class VenueUserList(ListAPIView): serializer_class = VenueUserListSerializer queryset = VenuePermissions.objects.select_related('user').select_related('venue').filter(signupvaildatestring=None) class VenueUserListSerializer(serializers.ModelSerializer): user = UserSerializer() venue = VenueSerializer() class Meta: model = VenuePermissions fields = ('user', 'venue', 'isvenueviewer', 'isvenueeventplanner', 'isvenueadministrator') now this returns all the venue permissions but if a user has multiple venues they have a permission on the view will return multiple objects of that user. so user with pk of 1 has three venues they have permissions on. You will see a 3 full venuepermission objects with user of pk 1 I would like to group these venuepermissions by user. I know the django ORM command is annotate https://simpleisbetterthancomplex.com/tutorial/2016/12/06/how-to-create-group-by-queries.html https://docs.djangoproject.com/en/1.11/topics/db/aggregation/#aggregating-annotations but I am not sure how to add that to my query. -

Django server in a Docker
I'm starting to develop an application with a Django back-end, and I wish to do it inside a Docker. I almost managed to do it, but I'm still having an issue. Currently I have two containers running : The first one contains my django app and the complete command is python3 manage.py runserver 0.0.0.0:8000 and the second one is hosting my database. My docker-compose.yml file is this one : version: '3' services: db: image: mysql:5.7 environment: MYSQL_ROOT_PASSWORD : root MYSQL_DATABASE : ml_gui back: build: ./back/ command: python3 manage.py runserver ports: - "8000:8000" depends_on: - db and my django settings concerning the database is : DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': 'ml_gui', 'USER': 'root', 'PASSWORD': 'root', 'HOST': 'db', 'PORT': '3306', 'OPTIONS': { 'init_command': "SET sql_mode='STRICT_TRANS_TABLES'", }, 'TEST': { 'CHARSET': 'utf8', 'COLLATION': 'utf8_general_ci', }, }, } The probleme is, when I do requests outside of the container (I've tried in my browser, with curl and with POSTMAN) on localhost:8000, I have no answer. But, when I do the same request inside the container with curl, it works. So my question is, how could I make those requests work from outside of the containers ? Thanks in advance -

How do I set up a development environment that is identical to the pythonanywhere production environment?
I'm trying to set up a development environment that is identical to the pythonanywhere live (production) environment. I uploaded a basic test site an discovered I have to change a few settings when I upload which I would definitely forget to do sometime. Ideally what i'd like to do is run a script from my command line that would create a fresh development environment for me to work with that completes all the setup tasks in one go, for example; set up a virtual environment, install all dependencies. My questions are: What do I need to set up? I'm working with django, so far I would have; set up virtual environment, install all dependencies (django and all the other things i would normally work with), potentially create all my project files and set up databases (if i didn't want a blank slate) Can someone point me in the right direction to find out how to do this? Thanks in advance. -

I have the following models: models.py class Tipo_mundo(models.Model): nome_tipo_mundo = models.CharField(max_length=80) descricao_tipo_mundo = models.TextField(max_length=600) class Mundo(models.Model): nome_mundo = models.CharField(max_length=80) descricao_mundo = models.CharField(max_length=200) atividades = models.ManyToManyField(Atividade, through='Jornada', related_name='mundos') tipo_mundo = models.ForeignKey(Tipo_mundo, on_delete=models.DO_NOTHING, related_name='mundos') and i want to put Mundo inside the Tipo_mundo admin edit page. As an inline to add as many Mundo's as i want. Refering to the list of Mundos already created. I want to create and edit just like a normal inline when i put admins like: admin.py class MundoInline(admin.StackedInline): model = Mundo extra = 1 class TipoMundoAdmin(admin.ModelAdmin): form = TipoMundoModelForm list_display = ('nome_tipo_mundo', 'descricao_tipo_mundo') inlines = [MundoInline,] i get: do not want it i want: something like this how can i do this??? -
ReactJS is no Rendering Component
I took this all from this example. Creating a React Login Page So I cannot take any credit. However, this page works fine. I am trying to retro fit it to pushing a React Video Player page. My code is as follows (Snippet from Axios Post): if (response.status == 200) { console.log("Login successfull"); var videoPlayer = []; this.setState( {isLoggedIn : true }); videoPlayer.push(<Videoplayer appContext={self.props.appContext} parentContext={this} />); self.props.appContext.setState({loginPage: [], videoPlayer: videoPlayer}); The existing code was this: var uploadScreen=[]; uploadScreen.push(<UploadScreen appContext={self.props.appContext}/>); self.props.appContext.setState({loginPage: [], uploadScreen: uploadScreen}) My code does not render the VideoPlayer Page and that code is from the standard example at this github ReactJS Video Player I have a feeling that it has to do with Context but I don't know enough about React or how to debug this using the Chrome tools. My backend is Django. I'm almost thinking of going back to using Jquery so I can get pages at least functioning but wanted to try and learn React. Any help would be great. The code above is just testing code so I could get some thing functional.
