Python syntax error without traceback?
I'm using django mongodb for a gym application website that I'm building for fun as my first web development project. I've just installed PyMongo, Django MongoDB, and I've created some models: from django.db import models from djangotoolbox.fields import ListField, EmbeddedModelField class Person(models.Model): name = models.CharField(max_length=200) class Workout(models.Model): date = models.DateTimeField('workout date') person = models.ForeignKey(Person, on_delete=models.CASCADE) lifts = ListField(EmbeddedModelField('Lift')) cardio = ListField(EmbeddedModelField('Cardio')) def __str__(self): return str(self.date) class Lift(models.Model): name = models.CharField(max_length = 200) #e.g. bench press, squat, deadlift, ... sets = models.ListField() # Stores a list of reps, each element corresponding to a set def __str__(self): return str(self.name) class Cardio(models.Model): name = models.CharField(max_length = 200) #e.g. running, cycling, etc. distance = models.IntegerField() #In metres. duration = models.IntegerField() #In minutes def __str__(self): return str(self.name) Now, I would like to start the shell to try to save some data.

Django Heroku and postgresql
I am new to publishing django apps on heroku. I have read their tutorials and figured I would start simple by modifying their template django project. So far everything was good. Then I made an app as one does, made a model and ran python3 manage.py makemigrations my_app python3 manage.py migrate and things seemed ok. I then pushed to heroku and there were no immediate complaints. However, now when I try to make save a new model I get the error: ProgrammingError at /my_app/ relation "my_app_myappmodel" does not exist LINE 1: INSERT INTO "my_app_myappmodel" ("field1", "field2", "field3") VALUES... odd... So I run this locally and everything works fine. I have tried cleaning my migrations, faking my migrations, squashing my migrations, etc (as other S.O. posts suggest) Nothing works. What is up and how do I fix it? -
Django model filter and do distinct by name
I have two models category class Category(models.Model): parent = models.ForeignKey() name = models.CharField(max_length=250) name parent ------- ------- vehicle 0 car 1 motorcycle 1 truck 1 bicycle 1 fff 0 .... Brand name category ---- --------- BMW car BMW truck BMW bicycle toyota car mercedes car mercedes truck someThing fff .... I want to create a queryset of Brand that is filtered by vehicle and to be distinct by name. so I can create a form in my template that will have a drop down filter with all the brands related to vehicle categories with no duplicate of names name category ---- --------- BMW car toyota car mercedes truck Is there any option to do it in a simple way,or do I need to write a function for that? I saw an example Select DISTINCT individual columns in django? but it returns a ValuesQuerySet and I need a QuerySet, and I prefer not to use ().distinct('someItem') that is supported only on PostgreSQL. -
Replacing django-admin default logo
I have generated a django-admin for my app and I can access the dashboard. But it contains a logo that says "django admin". I want to change it to my own custom logo. How can I do that? I have tried adding a base.html file to admin directory and tried to override but for some reason it's not working. It's code is as follows: {% extends "admin/base.html" %} {% load theming_tags %} {% load staticfiles %} {% block blockbots %} {{ block.super }} {# Using blockbots ensures theming css comes after any form media and other css #} {% render_theming_css %} <style type="text/css"> #header #branding h1 { background-image: url("bootstrap_admin/img/logo-140x60.png"); } </style> {% endblock %} {% block branding %} <a href="{% url 'admin:index' %}" class="django-admin-logo"> <!-- Django Administration --> <img src="{% static "bootstrap_admin/img/logo-140x60.png" %}" alt="{{ site_header|default:_('Django Admin') }}"> </a> {% endblock branding %} How can I achieve what I'm trying to? -

attempt to create queryset with filters at runtime does not return rows but SQL looks fine
Django 1.11.5 I am trying to build a query set with a chain of filters at runtime def query_cache(self, object: ObjectType, filters: List[MutableMapping] = None) -> QuerySet: filters = filters or [] object_name = object.value q = Cin7Cache.objects.filter(object_type=f"'{object_name}'") for f in filters: q = q.filter(**f) return q I get a queryset that always evaluates to no rows. The sql generated is fine. If I run it on postgresql, I get the rows I want SELECT "voga_cin7cache"."object_uniqueID", "voga_cin7cache"."object_type", "voga_cin7cache"."last_modified", "voga_cin7cache"."jdata" FROM "voga_cin7cache" WHERE ("voga_cin7cache"."object_type" = 'orders' AND ("voga_cin7cache"."jdata" -> 'createdDate') > '"2017-09-09"'); I can produce the same SQL with this: result_query = Cin7Cache.objects.filter(object_type='orders').filter(jdata__createdDate__gt='2017-09-09') and in this case, the result_query is not empty. The query in this case is: SELECT "voga_cin7cache"."object_uniqueID", "voga_cin7cache"."object_type", "voga_cin7cache"."last_modified", "voga_cin7cache"."jdata" FROM "voga_cin7cache" WHERE ("voga_cin7cache"."object_type" = orders AND ("voga_cin7cache"."jdata" -> 'createdDate') > '"2017-09-09"') it's not exactly the same: in the where clause, string constant 'orders' is not quoted the second time, but both give the same result set when evaluated in the postgresql console. WHen I inspect the queryset object, in the non-working case I have _result_cache = [] and in the second example, the working one, the query set has _result_cache=None Why is my first query set empty? -

Django celery and rabbitmq doesn't work until restart
I have problem with django, celery and rabbitmq. I use celery to send messages to FCM devices, but problem is that celery doesn't run that FCM command for sending messages, until I restart celery server. And when I restart celery, and try again, still same, I need to restart it again after every action. Example code: from __future__ import absolute_import, unicode_literals from celery import shared_task # firebase cloud messaging from fcm.utils import get_device_model Device = get_device_model() @shared_task def send_firebase_message(json, **kwargs): response = Device.send_msg(json, **kwargs) return response This is simple code, so this Device.send_msg doesn't fire until I restart celery server. Anyone got any solution for this? What can be the problem? -

Unit test in Django dont see correct redirect url for successfull login?
In my Django project I create custom admin page (NOT admin from Django). I have 2 login pages. One for admin, second for other users. Here below you can see urls.py file for admin.

How to differentiate cloned elements in jQuery and add events to cloned elements
I am trying to make deck builder. I want have this functionality, if I click on a card it shows in deck section, counter goes up. When I click on a card in deck section counter goes down and when it zero card disappears from deck section. My problem is how to differentiate cloned elements from original and how to add event to elements I am cloning. This is my JS script: $(".bronze").mouseup(function(e){ if (e.which === 1) { var counter = parseInt($(this).find(".bronze_counter").text(), 10) var card_name = $(this).attr("class").replace("bronze ", "") if (counter < 3) { counter += 1 $(this).find(".bronze_counter").text(counter); if (counter == 1){ $(this).clone().appendTo(".deck"); } else { $(".deck ." + card_name).find(".bronze_counter").text(counter); } } } }); And my template: <h3>Current Deck</h3> <div class="container deck"> </div> <div class="container"> {% for card in cards %} <span class="bronze {{ card.name | cut:'\'' | cut:' '}}"> <span><img src="{{ card.thumbnail_link }}" style="width:5%"> [</span> <span class="bronze_counter">0</span> <span>/3] </span> </span> {% endfor %} </div> Further I need to somehow save this deck in database. I was thinking about getting card names plus counter of each card and saving them in database. Am I digging a hole under myself? Thanks in advantage! Tomek Argasiński -

Wrong hyperlinks of Django Rest Framework with complex stack using SSL, AWS Load Balancer, Nginx and Gunicorn
I can't find out how to correctly set up nginx so my hyperlinks in API build by DRF are correct. My current configuration for nginx is: upstream web { ip_hash; server web:8000; } # portal server { listen 8000; server_name localhost; location / { proxy_set_header Host $host:$server_port; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header X-Forwarded-Proto $scheme; proxy_pass http://web/; } } nginx is running inside a container exposing port 8000 and maps it into internally running gunicorn (also in a container) also on 8000. So when I spin up the whole docker machinery, I can nicely access localhost:8000/api and links are rendered OK. Even when I access it using different domain (e.g. if I set in /etc/hosts: 127.0.0.1 mytest.com), the URL and port get passed correctly to the DRF and links are rendered as expect. But this service must sit behind AWS Load Balancer with certificate using SSL. Hostname on this LB is set otherdomain.com and it redirects traffic to the machine where the above nginx is run using HTTP on port 8000. Then, when try to access it using https://otherdomain.com/api, links are rendered as http://otherdomain.com:8000/api/ <- hence wrong scheme (http instead https) and wrong port (8000 instead of 80/443).

Case WHEN to fetch data from different model when data is not zero
I have a simple model like this: class Payments(models.Model): dt=models.DateField() payer=models.IntegerField(default=0) If a member pays for himself, payer=0. But sometimes his support group (there are many groups) can pay for him/her and when that happens, the payer holds the ID of the support group. I didn't want to implement a relationship here. Now I want to list payments made but when payer>0, to get name of the subgroup that actually paid for the member. data=Payments.objects.filter(**build_filters['filters']).annotate(support_group_name=Case(When(payer__gt=0, then=Value('support group name goes here'), default=Value(''), output_field=CharField())).values('support_group_name','id','dt') I already have a function that use from various locations which returns name of a support group provided with id.
