Python dict_values ([...]) is not JSON serializable [duplicate]
This question already has an answer here: Specializing JSON object encoding with python 3 1 answer I'm trying to get up and running with an API that already works for some others (who, of course, I can't consult right now). I get an error for one specific endpoint: TypeError: dict_values([ {'unregistered_users': 2, 'group_name': 'a', 'registered_users': 9, 'total_users': 11}, {'unregistered_users': 0, 'group_name': 'b', 'registered_users': 4, 'total_users': 4}, {'unregistered_users': 0, 'group_name': 'c', 'registered_users': 4, 'total_users': 4}, {'unregistered_users': 4, 'group_name': 'd', 'registered_users': 5, 'total_users': 9}, {'unregistered_users': 0, 'group_name': 'e', 'registered_users': 7, 'total_users': 7}, {'unregistered_users': 0, 'group_name': 'f', 'registered_users': 7, 'total_users': 7}]) is not JSON serializable From what I can tell, this is valid JSON, and there's no reason why it shouldn't be serializable.

Django query to compare two foreignkey fields?

Pinax project does not load any static file in pythonanywhere server
I have a pinax account project working fine in my local environment and I want to deploy it to a serve. When I try it to do it, it happens the same problem as if I install the pinax account project in the pythonanywhere server, the website shows everything but it cannot access any static file.

I tried to do it manually and with pinax-cli as well I also modified my WSGI: path = '/home/manolodewiner/mysite' os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings' In my local environment it works perfect, so what could be the problem? -
Django model doesn't show on admin panel when created through Celery
I am creating some dynamic Django models through a celery process. When I created these models without using celery, they appeared on the admin panel, but when I ran the process through celery, the models do not appear on the admin page. I know the model are created because when I run makemigrations after, it does recognize the newly created models. My code is something like this: signals.py @disable_for_loaddata def email_change(sender, instance, **kwargs): from email.tasks import update_email update_email.delay(instance.pk) tasks.py @shared_task def update_email(id): from email.views import save_email save_email(id) views.py def save_email(id): from email.models import EmailType instance = EmailType.objects.get(pk=id) model = type(instance.__str__(), (Email,), attrs) admin.site.register(model, admin_opts) reload(import_module(settings.ROOT_URLCONF)) clear_url_caches() call_command('makemigrations') call_command('migrate') Can anyone point out why this makes the model not show up on the admin panel? -

Django- getting a list of foreign key objects

I have tried: children = ParentModel.objects.values_list('child', flat=True) However this returns a list of ChildModel ids, rather than the full objects.

How to send an object back to Django view and access it by indexing
In my HTML I have an object data .Data was originally retrieved from a SQL query in Django in views.py and passed on to the HTML using render() data looks like this data1= { 0:{ pk:1, model:"binaryQuestionApp.painting", fields: {title:'Pearl',artist:"vermeer"}, }, 1:{ pk:2, model:"binaryQuestionApp.painting", fields: {title:'Sand',artist:"vermeer"}, } } I use the following JS so send data back to views.py (I create csrftoken using this question) function post_data() { var postdata = { 'data': data, 'csrfmiddlewaretoken': csrftoken }; $.post('', postdata); // POST request to the same view I am now }; Now, data is being send back to the server, but I'm having trouble accessing it. I have this in my views.py if request.method == 'POST': data = request.POST # so far it works. But i can not index like this: print(data[0]['pk'] # instead I need to index it strangely, like this: print(data['data[0][pk]']) # note the entire key is a string How can I send data to Django so that i can access it in views.py using data[0]['pk']? -
Django-import-export can't import MultiSelectField Checkbox
I am using django-import-export in an app of my web project. my class.py file is the following: class Article(models.Model): siret = models.CharField(max_length=16) newspaper = models.CharField(max_length=200) writer = models.CharField(max_length=1000) TOPIC_TYPE = ( ('Sport', 'Sport'), ('Food', 'Food'), ('Business', 'Business'), ('Music', 'Music'), ('Art', 'Art'),) topics = MultiSelectField(choices = TOPIC_TYPE) Note that topics is a MultiSelectField. In admin.py I simply followed the django-import-export tutorial, hence: class ArticleResource(resources.ModelResource): class Meta: model = Article exclude = ('is_true', ) class ArticleAdmin(ImportExportModelAdmin): resource_class = ArticleResource admin.site.register(Article, ArticleAdmin) The issue while importing data is as you guess with the "topics" variable. I first exported an xlsx file to see the way this variable is exported. This is literally how: siret ... topics ----------------------------------- 0000068591590 ... Music, Art 0000068591595 ... Business, Beauté 0000068591600 ... Art The issue, is with data importing. I simply tried to import back the above exported file, by changing "siret" numbers. Once imported, in the admin interface, I was surprised, Django laughed at me by selecting only the first topic for each article in the available CheckBoxes (only Music for 0000068591590, only Business for 0000068591595). Hence I tried to import through: Music, Art (as exporting way) ['Music','Art'] [Music, Art] 'Music', 'Art' However It's not working. Ty -
Customizing django admin, should I be editing the files under site-packages or should I be overriding?
I started my project using the typical django-admin startproject mysite command. When I jump to method in visual studio on admin functions/methods I notice it brings me to the python environment site-packages, where all of the admin code resides. Should I be editing the code in these files or overriding them in other areas of my application?

Command silk_clear_request_log doesn't delete anything
I am running Silk on my staging server. I want to clear space in this database, so I run the following command. ../../bin/python manage.py silk_clear_request_log --settings ServiceName.settings.staging I expect to see output that it deletes things, but I don't get any output. After a few seconds, the prompt returns. No data is cleared in the database. What could be causing this behavior? How would I start debugging this issue? -
Django : Multiple column form not being saved to the database
I am new to django so please pardon me if this sounds ridiculous. I have gone through the django docs and all similar questions but i cant seem to figure it out.I have a form that takes in the marks of multiple exams of multiple students in the form of a table( using datatables). What I basically need is, for a table to be displayed, which will show the values currently present in the database but which can be edited and saved again. And although the entire table is displayed, editing only few of the table cells should also be allowed. In the table , the roll numbers of the students are from the database and since those don't change I am not passing them to the forms . The problem I face is ,though there isn't any error, the form.is_valid() returns true but form.save() doesn't save the values to the database. What i suspect the problem to be is that it probably doesn't know the roll no. pertaining to the row of data that its received and thus cannot place it in the database. I don't really know the mistake. Help will be deeply appreciated. Thank you. html form … -
Django ORM query guidance
My model includes a company, pub_date, and report_type fields. I have written two model methods: num_prev_covered and is_active and created a model manager. num_prev_covered: every new 'open' report is an increment of 1 is_active: if 'open' report has been created, but no 'close' report Model methods cannot be used in Django query filters (Django, query filtering from model method) Question: How do I write a query that performs the same functionality as the is_active method?
