AttributeError: module 'django.db.models' has no attribute 'get_models'
why am i getting issue when calling for get_model() function? Here is what I am trying to do @classmethod def get_content_models(cls): """ Return all Package subclasses. """ is_content_model = lambda m: m is not Package and issubclass(m, Package) return list(filter(is_content_model, models.get_models())) This used to work before but now after updating to new django, it's throwing an error. How can this be resolved? -

How to interpret this parsing error of the image variable that was rendered in the django template in heroku?
The error says (ImageFieldFile' object is not subscriptable) I wanted to call an image url using an image variable in the html django templates. I thought it was a date-util version error as i have been seeing other users recommend using date-utl version 1.5 which heroku only works with even after deprecating the date-util 2.8 to v 1.5 it still didnt work. SyntaxError at / invalid syntax (parser.py, line 158) this is where the error occured src="{{ tweet.user.profile.image.url }}" Error was this SyntaxError at / invalid syntax (parser.py, line 158) Request Method: GET Request URL: https://meawesometwitterapp.herokuapp.com/ Django Version: 2.2.2 Exception Type: SyntaxError Exception Value: invalid syntax (parser.py, line 158) Exception Location: /app/.heroku/python/lib/python3.7/site-packages/botocore/credentials.py in , line 27 Python Executable: /app/.heroku/python/bin/python Python Version: 3.7.3 Python Path: ['/app/.heroku/python/bin', '/app', '/app/.heroku/python/lib/python37.zip', '/app/.heroku/python/lib/python3.7', '/app/.heroku/python/lib/python3.7/lib-dynload', '/app/.heroku/python/lib/python3.7/site-packages'] Server time: Mon, 29 Jul 2019 09:32:44 +0000 I cant intepret the error in the production heroku django app -

Change admin form name for overridden User
I've overridden the standard django User by extending AbstractUser. Now this all works fine, but for some reason I can't make the admin display "Profiles" (the name of the model now set in settings.AUTH_USER_MODEL instead of "Users". This is my code for admin.py for the profiles app from django.contrib import admin from django.contrib.auth.admin import UserAdmin from django.contrib.auth.forms import UserChangeForm from .models import Profile class ProfileChangeForm(UserChangeForm): class Meta(UserChangeForm.Meta): model = Profile verbose_name_plural = "Profile" class ProfileAdmin(UserAdmin): form = ProfileChangeForm # fieldsets = UserAdmin.fieldsets + ((None, {"fields": ("some_extra_data",)}),) fieldsets = UserAdmin.fieldsets admin.site.register(Profile, ProfileAdmin) I'd figured there should be some Meta setting I can put in here, but after significant amounts of googling I can't find anything. I'm sure this is a simple answer - could somebody point me in the right direction? I've tried setting "name" and "verbose_name", but no joy. At the end of the day, I could live with this, as it's just the admin interface, but it's bugging me ... -

gunicorn keeps rebooting it's worker when Django is starting Python project
I am running a web-based project with a data science focussed backend which is hosted on a Microsoft Azure cloud server. Large deep learning models need to be loaded and initialized when Django starts the project. I am running the project through an nginx server which communicates to the Django server through gunicorn. If I run the project on the same Azure cluster through Django alone (not using nginx or gunicorn) it initializes and starts just fine. However, when I run it on nginx through gunicorn, one of the workers keeps rebooting as the project is starting up (it takes maybe ~2 mins to initialize. Here is the output from the gunicorn command when I try to start the Django project: user@host:/home/libor/libor_transition/libor_transition_api$ sudo gunicorn --pythonpath="$(pwd)" --log-level=DEBUG -t 1000 libor_transition_api.wsgi:appli> [2019-07-29 08:43:44 +0000] [33808] [DEBUG] Current configuration: config: None bind: ['127.0.0.1:8000'] backlog: 2048 workers: 1 worker_class: sync threads: 1 worker_connections: 1000 max_requests: 0 max_requests_jitter: 0 timeout: 1000 graceful_timeout: 30 keepalive: 2 limit_request_line: 4094 limit_request_fields: 100 limit_request_field_size: 8190 reload: False reload_engine: auto reload_extra_files: [] spew: False check_config: False preload_app: False sendfile: None reuse_port: False chdir: /home/libor/libor_transition/libor_transition_api daemon: False raw_env: [] pidfile: None worker_tmp_dir: None user: 0 group: 0 umask: 0 initgroups: False … -

Overwriting nested serializer's create method throws TypeError: create() got multiple values for keyword argument
I want to send data to my API. My data structure is nested. So I am trying to overwrite the create method following the docs and SO. When sending data it gives me the following error: TypeError: create() got multiple values for keyword argument 'graph' My data structure looks like this: { "project": "project1", "name": "Graph1", "description": "Graph belongs to Projekt1", "nodes": [ { "id": 2, "name": "Node1 of Graph 1", "graph": 3 } ] } Her is what I am trying in my serializer (which is pretty standard I assume): class GraphSerializer(serializers.ModelSerializer): nodes = NodeSerializer(many=True) class Meta: model = Graph fields = ('project', 'name', 'description', 'nodes', ) def create(self, validated_data): nodes_data = validated_data.pop('nodes') graph = Graph.objects.create(**validated_data) print(graph) for node_data in nodes_data: Node.objects.create(graph=graph,**node_data) return graph The error is in the for loop. When I debug though and print graphit give me back just one Graph (Graph1). So I don't understand why I should get a multiple values error.

django 2.2.3-Django 404 error ('Page not found') after runserver

Using the URLconf defined in tweetme.urls, Django tried these URL patterns, in this order: ^admin/ ^static/(?P<path>.*)$ The empty path didn't match any of these.

Return data based on model flag for OnetoOne Nested Serializer
I am using a nested serializer for onetoone mapping for a model offer. But i want the nested serializer to only return data if the fllag in the model instance of nested serializer is set to true. I guess to_representation will not work here as it will receive an object instance rather than queryset. Model : class Offers(models.Model) : brand = models.CharField(max_length=100,blank=True,null=True) hospital = models.OneToOneField('hospital.Providers',to_field='hospital_id',on_delete=models.SET_NULL, related_name='hospital_offer',blank=True,null=True) validity = models.PositiveIntegerField(default=0) terms = models.CharField(max_length=500,blank=True,null=True) discount = models.PositiveIntegerField(default=0) logo = models.CharField(max_length=100,blank=True,null=True) active = models.BooleanField(default=True) created_date = models.DateTimeField(auto_now_add=True) Serializer : class ProviderOffersSerializer(serializers.ModelSerializer) : class Meta : model = Offers fields = ('brand','id') class ProviderSerializer(serializers.ModelSerializer): hospital_offer = ProviderOffersSerializer(read_only=True) network = NetworkSerializer(read_only=True) class Meta: model = Providers fields = ('hospital_id','hospital_name','hospital_offer','pincode','network') Now ProviderSerializer should return data for offer only if active is True.

How to override the field value for modelformset in CreateView?
I use different qwerysets for modelformset of the same model. The first filter for grouping values from queryset I define in forms.py class SkillCreateFrameworkForm(SkillBaseCreateForm): def __init__(self, *args, **kwargs): super(SkillCreateFrameworkForm, self).__init__(*args, **kwargs) self.fields['technology'].queryset = Technology.objects.filter(group__name="Framework") class SkillCreatePLanguageForm(SkillBaseCreateForm): def __init__(self, *args, **kwargs): super(SkillCreatePLanguageForm, self).__init__(*args, **kwargs) self.fields['technology'].queryset = Technology.objects.filter(group__name="Programming language") The next step is to filter out the values that are already bound to the user being edited. To do this, in get_context_data I get a list of all the technologies that the user already has. employee_current_technology = Technology.objects.filter(skill__employee__id=self.kwargs['pk']) get_context_data def get_context_data(self, **kwargs): context = super(SkillTestCreateView, self).get_context_data(**kwargs) employee_current_technology = Technology.objects.filter(skill__employee__id=self.kwargs['pk']) context['formset_framework'] = SkillFrameworkFormSet() context['formset_planguage'] = SkillPLanguageFormSet() context['tech_group'] = Techgroup.objects.all() return context How do I now apply a filter to context['formset_framework'] that excludes technologies that the user already has?
