I am trying to make google map api 3 markers using users' locations in Geodjango, and i encounter Internal Server Error 500 in rendering the google map and markers. On the CMD console , i get TypeError: 'GeoQuerySet' object is not callable. Can you please suggest a solution and explain the cause for the exception?

I am trying to pass a queryset as a JSON object: structure=Fund.objects.all().values('structure').annotate(total=Count('structure')).order_by('-total') However, querysets aren't Json Serializable therefore, I modified my code: from django.core import serializers structure=serializers.serialize('json',Fund.objects.all().values('structure').annotate(total=Count('structure')).order_by('-total')) But I get this error: AttributeError: 'dict' object has no attribute '_meta' and this is my queryset: <QuerySet [{'total': 106, 'structure': 'Corp'}, {'total': 43, 'structure': 'Trust'}, {'total': 2, 'structure': 'OM'}, {'total': 0, 'structure': None}]> -

Ordenate django query by user
I'm trying to retrieve the objects that some user created and show in my API, but i need to ordenate this objects by this user. If use order_by('created_by') the queryset will be ordenate by user's id (not necessarily the id that i want, but descending order), the firsts results must be the Opportunity that my user created followed by the others. I thought this could resolve, but q lost the ordenation with union: def get_queryset(self): user = self.request.user q_all = Opportunity.objects.all().exclude(created_by=user.id) q_user = Opportunity.objects.filter(created_by=user.id).exclude(archived=True) q = q_user | q_all return q -

Django Autocomplete Light List Object has no Attribute Queryset
Please look at my edit at the end of my code as well. I'm attempting to implement django-autocomplete-light (dal) for a single field. Following the tutorial, I turn up this error: 'list' object has no attribute 'queryset'. I have seen this question: django-autocomplete-light error = 'list' object has no attribute 'queryset'. It did not resolve my issue. Why is this error occurring? What can I do to combat this? I have two models: class Entity(models.Model): entity = models.CharField(primary_key=True, max_length=12) entityDescription = models.CharField(max_length=200) def __str__(self): return self.entityDescription class Action(models.Model): entity = models.ForeignKey(Entity, on_delete=models.CASCADE, db_column='entity') entityDescription = models.CharField(max_length=200) action = models.CharField(max_length=50) def __str__(self): return '%s' % self.entity I have a model form: class ActionForm(ModelForm): class Meta: model = Alert fields = '__all__' widgets = { 'entityDescription': autocomplete.ModelSelect2(url='eda') } I have a view: class EntityDescriptionAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): qs = Entity.objects.all() return qs I have a urls.py: urlpatterns = [ url( r'^eda/$', views.EntityDescriptionAutocomplete.as_view(), name='eda', ), ] Thank you for any insight you all might have. Edit: I changed... widgets = { 'entityDescription': autocomplete.ModelSelect2(url='eda'), } ...to... widgets = { 'entityDescription': autocomplete.Select2(url='eda'), } ...this allowed my page to render, but the autocomplete field is an empty dropdown. Why is it empty? -

Installing django also creates migrations
To make a long story short: when I install django it comes with migrations that I deleted in the past. Here is what I do: $ mkvirtualenv foo $ (foo) pip install django Collecting django Using cached Django-1.11.5-py2.py3-none-any.whl Collecting pytz (from django) Using cached pytz-2017.2-py2.py3-none-any.whl Installing collected packages: pytz, django Successfully installed django-1.11.5 pytz-2017.2 Now when I look in the directory where the venv is created I can see migrations in the default django apps (admin, user, ect.) I also see migrations in a brand new project. This problems started after I tried to reset my migrations. I deleted the migrations from each app and dropped all the tables. Then I removed the migrations in the venv, while doing this I accidentally removed a django app. The missing app forced me to uninstall and install django. Even when I tell pip not to use the cache --no-cache-dir, I still get the migrations. -

Release Celery lock when transaction is committed
I use a Celery task in my Django project with a lock as described in this article. It works great, but my task creates an object and I don't want that the lock was released before the object is committed in the database.

Properly reach Google Cloud SQL via proxy on Bitbucket Pipelines
Whats the proper way to proxy a Cloud SQL Database into Bitbucket Pipelines? I have a Google Cloud SQL Postgres Instance (And also tried a MySQL DB). Opening all ports to connections allows bitbucket pipelines to properly deploy my Django based Google App Engine Project, based off this example pipeline - https://github.com/GoogleCloudPlatform/continuous-deployment-bitbucket/blob/master/bitbucket-pipelines.yml However, when I try to limit the access to the Cloud SQL instances and use cloud_sql_proxy instead, I can properly deploy locally, but Bitbucket will always fail to find the SQL Server My bitbucket-pipelines.yml looks something like this: - export CLOUDSDK_CORE_DISABLE_PROMPTS=1 # Google Cloud SDK is pinned for build reliability.

When I add() to a ManyToMany relationship, does it replace the previous records?
I'm creating a set of view for an app that adds and edits teams and volunteers. Volunteers can take part of as many teams as they wish, and a few of them are set as team leaders. Due to the need for flexibility of the process (I guess), I've left both items as separated (I'm open to suggestions on this, though!) and I'm trying to set consistency on the views. For example, I want to make sure that every time I add a team leader on one view, they are also enrolled as a team member. class Team(models.Model): team_name = models.CharField(max_length=30, null=True, blank=True) leaders = models.ManyToManyField(Volunteer, related_name='leaders', blank=True) enrolled = models.ManyToManyField(Volunteer, related_name='enrolled', blank=True) class Volunteer(models.Model): name = models.CharField(max_length=30) I have a view on which I'm doing just this. After saving the form, I take each of the leaders and add them to the enrolled field. However, when I add them, I find that the previous values of enrolled on the field has been replaced by the new values I added. I could just save the previous values in a variable and reapply, but is it supposed to work this way? class TeamUpdate(LoginRequiredMixin, UpdateView): form_class = TeamCreateForm model = Team def … -

Django: How is <classname>_set attribute created in models.Model subclass?
In Django, I can have a model Question and a model Choice: class Question(models.Model): ... def __str__(self): return self.question_text class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) ... def __str__(self): return choice_text I can then do this: >>>q = Question(question_text = 'How are you?', pub_date = timezone.now()) >>>q.choice_set.all() <QuerySet []> The q.choice_set, according to my understanding, accesses the set of Choice objects in our database which refer to q by their foreign key.

Create Permission without a ContentType model

pushing django migrations into source control
I've deployed my Django application for a while now, but all this time I've kept migrations out of souce control. What I did was run makemigrations and migrate twice-- once in development, and once in production. So now how can I seamlessly put my migrations into source control? Theoretically the migrations should be the same (given my models.py files haven't changed), but how would I go about matching my migrations up without accidentally overriding something? -

Below is all 3 models, Data that gets sent and my view logic Payfast model class PayFastOrder(models.Model): # see http://djangosnippets.org/snippets/2180/ __metaclass__ = readable_models.ModelBase # Transaction Details m_payment_id = models.AutoField(primary_key=True) pf_payment_id = models.CharField(max_length=40, unique=True, null=True, blank=True) payment_status = models.CharField(max_length=20, null=True, blank=True) item_name = models.CharField(max_length=100) item_description = models.CharField(max_length=255, null=True, blank=True) amount_gross = models.DecimalField(max_digits=15, decimal_places=2, null=True, blank=True) amount_fee = models.DecimalField(max_digits=15, decimal_places=2, null=True, blank=True) amount_net = models.DecimalField(max_digits=15, decimal_places=2, null=True, blank=True) # The series of 5 custom string variables (custom_str1, custom_str2...) # originally passed by the receiver during the payment request. custom_str1 = models.CharField(max_length=255, null=True, blank=True) custom_str2 = models.CharField(max_length=255, null=True, blank=True) custom_str3 = models.CharField(max_length=255, null=True, blank=True) custom_str4 = models.CharField(max_length=255, null=True, blank=True) custom_str5 = models.CharField(max_length=255, null=True, blank=True) # The series of 5 custom integer variables (custom_int1, custom_int2...) # originally passed by the receiver during the payment request. custom_int1 = models.IntegerField(null=True, blank=True) custom_int2 = models.IntegerField(null=True, blank=True) custom_int3 = models.IntegerField(null=True, blank=True) custom_int4 = models.IntegerField(null=True, blank=True) custom_int5 = models.IntegerField(null=True, … -
I'm wondering what I can do to improve this full-text search code in my Django app
The code works such as it is, but I'm have feeling I'm building the query incorrectly. def search_results(request): terms = request.GET['search_terms'].split() vector = SearchVector('title', 'subtitle', 'header_image', 'header_image_caption', 'excerpt', 'body', 'tags__name',) query = SearchQuery('') for term in terms: query = query | SearchQuery(term) results = Article.objects.annotate(search=vector).filter(search=query).order_by('-pub_date',).distinct('pub_date',) return render(request, 'etherblog/search_results.html', context={'articles': results, 'terms': terms}) Also getting this error triggered by search engines I believe: File "/home/danjewett/webapps/ether/ether/etherblog/views.py" in search_results 102. terms = request.GET['search_terms'].split() File "/home/danjewett/webapps/ether/etherenv/lib/python3.5/site-packages/django/utils/datastructures.py" in __getitem__ 85. raise MultiValueDictKeyError(repr(key)) Exception Type: MultiValueDictKeyError at /search_results/ Exception Value: "'search_terms'" Request information: USER: AnonymousUser -
DjangoRestFramework with Oracle an no id field
I'm trying to get Django Rest Framework (3.6.4) running with a simple model. However, the model does not contain an ID field so I'm getting django.db.utils.DatabaseError: ORA-00904: "HCM_JOBS"."ID": invalid identifier The PK is going to be a composite of three fields in the model. I tried setting a custom id field in my serializer via class HcmJobsSerializer(serializers.HyperlinkedModelSerializer): id = serializers.ReadOnlyField(source="HcmJobs.position") class Meta: model = HcmJobs fields = '__all__' but I still get the same ORA-00904 error from it trying to get an id field. Most of what I've found on StackOverflow has been on how to deal with the id field, not how to deal with not having one. I don't have control over the tables themselves so I can't add in an id field. Any idea how I can use the framework without an ID field?
