I have a running instances which shows the site properly on aws. what's included to run the site are django, nginx, uwsgi with elastic ip I have created an image of the instances. Launch the instance which now I have a second instance which is the same as the first one. The second instance just have normal floating ip. When I input the ip into the browser, I was expecting to see my site too else just a long loading until it timeout since I didn't do any configurations in site-available yet. Anyways, I was then able to see only the nginx welcome page. I went to the site-available, put the ip into server_name, also I setup a dns for a subdomain name. After the changes, I restarted uwsgi. I tried using ip and subdomain on browser, but still showing the nginx welcome page. There isn't even an error. Does someone have any idea why or advice what I do try? They are both the same settings, shouldn't it work properly? P.S. I then tried moving the elastic ip from first instance to the second instance...I used the domain of first instance in browser...then my site pops up not the … -

Django Rest Framework: Patching a OneToOneField
I need help with a PATCH request using Django rest framework. I have a User model that inherits from AbstractBaseUser which has 2 fields: name and email. The email field is unique. Then I have a DojoMaster model that has a OneToOne relationship with the User model: models.py class DojoMaster(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) phone = models.BigIntegerField() username = models.CharField(max_length=100, unique=True) country = models.ForeignKey(Country, on_delete=models.CASCADE) I am able to POST a "dojomaster" to the application. Let's say the "dojomaster" POST looks like this: POST payload { "user": { "name": "XYZ", "email": "xyz@mail.com", "password": "2He$8Mv*" }, "phone": 2685211, "country": 575, "username": "iAmXyZ" } Now the "dojomaster" wants to change some of these details, so a PATCH request is sent: PATCH payload { "user": { "name": "XYZ", "email": "xyz24@mail.com", #change email "password": "p@55w0rd" #change password }, "phone": 3972925, #change phone number "country": 575, "username": "iAmXyZ" } To achieve this, I created the following in my serializers.py: class UserSerializer(serializers.ModelSerializer): class Meta: model = User fields = ('name', 'email', 'password') class DojoMasterUpdateSerializer(serializers.ModelSerializer): user = UserSerializer(required=True) def update(self, instance, validated_data): user_data = validated_data.pop('user') user = User.objects.update(**user_data) instance.user = validated_data.get('user', user) instance.username = validated_data.get('username', instance.username) instance.phone = validated_data.get('phone', instance.phone) instance.country = Country.objects.get( country=validated_data.get('country', instance.country) ) … -
Changing Tableau display name of Django model fields
I have been using Django ORM with Tableau reports without many issues, by providing the label for the fields explicitly. E.g. my_field = models.CharField("A Better Looking Name", max_length=500) So the above shows up in Tableau reports as "A Better Looking Name". However, when using the contenttype framework, I am unable to provide the labels for field columns: object_id = models.TextField('Give whatever name here it does not work') content_type = models.ForeignKey(ContentType, ...) my_field = GenericForeignKey("content_type", "object_id") I have tried providing verbose_name for object_id, renaming my_field, etc. None of them translate to a changed label in the PostgreSQL database (and hence in Tableau). Note that I am NOT attempting to label these for Admin etc, so short_description is not of use here. Any input on how to use "A Better Looking Name" for the generic ID in Tableau would be appreciated. -

Issue With Same Inbox Subject as Multiple Objects
I'm using this Django Messages package. Messages in the inbox with the same subject keeps showing up more than once depending on the number of times a sender and the recipient receives messages. I want a situation whereby messages with the same subject will only show up once in the inbox and not twice or thrice. Kindly check the attached image for what I mean. I've looked into the code and I did this message_list = Message.objects.inbox_for(request.user).values('subject').distinct() But still not working. -
Django assign score to the field based on the choice and calculate the sum of field scores
I am new to django and have been breaking my head for last couple of days over this problem. So I have something similar in models.py: class RType(models.Model): rtype_name = models.CharField(max_length=10, verbose_name="Severity", default = "") rtype_score = models.IntegerField(max_length=10, verbose_name="Severity Score", default = "") def __str__(self): return self.rtype_name class Environment(models.Model): environment_name = models.CharField(max_length=100, verbose_name="Environment") environment_sensitivity = models.ForeignKey(RType, on_delete=models.CASCADE, blank=True, null=True, verbose_name="Environment sensitivity", default = "") def __str__(self): return self.environment_name class UserGroup(models.Model): user_group_name = models.CharField(max_length=100, verbose_name="User Group") user_group_sensitivity = models.ForeignKey(RType, on_delete=models.CASCADE, blank=True, null=True, verbose_name="User Group sensitivity", default = "") def __str__(self): return self.user_group_name class Subject(models.Model): name = models.CharField(max_length=500, verbose_name="Subject", blank=True) question1 = models.ManyToManyField(UserGroup, verbose_name="User group", default="", blank=True) question2 = models.ManyToManyField(Environment, verbose_name="Environment", default="", blank=True) r = ?? Here are some things I want to achieve: Sum rtype_scores for each question (question1, question2) even if there are multiple choices Count number of choices made in question1 Make other calculations like / * + - on inputs from question, question and count results Store the outcome of calculations in r Is this even possible or am I doing everything incorrectly? -
Set testing options while django doctesting
Following these posts, I have managed to run my doctest within django with: # myapp/tests.py import doctest def load_tests(loader, tests, ignore): tests.addTests(doctest.DocTestSuite()) return tests Then running: python manage.py tests However, since I am used to test my (non-django) scripts with the simple command: py.test --doctest-modules -x I am now quite confused about: testing procedure not stopping after first failure (my good'ol -x) (so I get flooded with results and I need to scroll back all the way up to the first problem each time) option # doctest: +ELLIPSIS not being set by default. How do I set this kind of options from this django load_tests() hook? -

How to save user id to inline models in Django admin?

BaseInlineFormSet methods don't support this. -

routeParams keep returning empty dictionary
i'm using django/angular and trying to retrieve the 1234 parameter in url in http://localhost:8000/dashboard/1234.

Showing current user instance in edit profile form
So I have this view which displays my UserProfileForm. As far as I can tell the logic of what's going on makes sense. It should (1) automatically pull the profile info from the currently logged in user and (2) save it when submitted. The only problem is that it does neither of those two things. I have looked around SO for how to do this as well as some other tutorials but it still won't do the trick. The view: def editProfileView(request): if request.method == 'POST': form = UserProfileForm(request.POST, instance=request.user) if form.is_valid(): form.save() return redirect('users:explore') else: form = UserProfileForm(instance=request.user) args = {'form':form} return render(request, 'users/userprofile_edit_form.html', args) Not sure how relevant seeing the form itself is but this is what it looks like: class UserProfileForm(forms.ModelForm): first_name = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) profile_pic = forms.ImageField(widget=forms.FileInput(attrs={'class':'form-control mb-3'}), required=False) location = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) title = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) user_type = forms.ChoiceField(choices=USER_TYPE_CHOICES) website = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) about = forms.CharField(widget=forms.Textarea(attrs={'class':'form-control mb-3'})) twitter = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) dribbble = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) github = forms.CharField(widget=forms.TextInput(attrs={'class':'form-control mb-3'})) class Meta: model = UserProfile fields = ( 'first_name', 'profile_pic', 'location', 'title', 'user_type', 'website', 'about', 'twitter', 'dribbble', 'github' ) -

Connection Pooling across several processes in Pymongo
I'm a rather new to Pymongo and Mongodb itself and right now i'm working on a Django based project that uses a process to perform some cruds on a Mongodb instance we are using PyMongo and since this is web application many instances might be running at the same time so my questions is about the connection pool setup. what's the best practice to use the Pymongo keeping in mind performance for this specific case: connection pool? At the beginning we had a new instace of Pymongo created: MongoClient(host, port, maxPoolSize=200) every time the endPoint was called. i understand that every instance is using it's own connection Pool but when you have many instances running..do you have multiple connections pool per Mongodb instance? So we came with a modification and now instead creating new instances we just use static method which actually serves the connection method and this is shared across all of the PyMongo instances being invoked is this a good solution or is it better the first one (instance per call) or is there another option that i should follow?? I would appreciate the comments or suggestions from other guys more experienced in this matter. Thanks in advanced … -

getting error: 'Each option setting in configuration file must be a map ' while deploying django app in EBS
I am trying to deploy a django application in EBS. I am following the aws tutorial but I'm unable to deploy. The error says: 'ERROR: Each option setting in configuration file reclutapp_project/.ebextensions/django.config in application version app-db14-180308_133135 must be a map. Update each option setting in the configuration file.'

I've also tried this with no success. I've also checked indentation and format. I've also tried with json format getting the same error. I've deleted elastickbeanstalk config file and created a new environment, but nothing seems to work. I assume the problem relies on the config file format, but I'm using both yalm and json compatible formats. I am using Django 2.0 and Python 3.6 environment. Any suggestions? -
