How to import python module into a dictionary?
This is more a Django specific question, let's say I have settings/base.py as below: DATABASES = {...} SECRET_KEY = '1234567' And I would like to import this into my development.py, but as a dictionary, something like: from .base import * as base_dict #wrong syntax here # adjust database connection base_dict['DATABASES'] = {...} # merge to development.py merge_dict_to_settings(base_dict) I tried base.__dict__ but it contains a lot more stuff than I needed. -
Django settings when using pgbouncer
I have a Django website with Postgresql backend, for which I'm utilizing pgbouncer for db connection pooling (transaction mode). The application and the DB reside on separate servers (1 server each). I have installed pgbouncer on the application server. My question is: what should the config be in settings.py? Note that I'm using Unix sockets for connecting to pgbouncer. My current settings.py contains: DATABASE_URL = 'postgres://user1:pass1@host:5432/db1' DATABASES = { 'default': dj_database_url.config(default=DATABASE_URL) } Relevant sections of pgbouncer.ini are: [databases] db1 = host=xx.xxx.xxx.xxx port=5432 dbname=db1 listen_addr = * listen_port = 6432 auth_type = md5 unix_socket_dir = /var/run/postgresql pool_mode = transaction max_client_conn = 200 default_pool_size = 300 userlist.txt contains: "user1" "pass1" Note: I'm using a legacy Django version, where pgbouncer is my best option for db connection pooling. -

change timezone in mod_wsgi on openshift
I deployed a django application on openshift and I'm running it in productive mode. When I look at the logs (python.log) in $OPENSHIFT_LOG_DIR I see messages from my django app and the apache server/mod_wsgi. These two sources use different format of their messages - I know I can change the log format of my django application to use the same format as the apache log, but the two sources are also using different time zones. The django application runs in Berlin/Europe time zone whereas the apache log messages uses Eastern Standard time. This makes it uncomfortable to read the logs: 195.195.195.12 - - [25/Oct/2016:15:14:09 -0400] "GET /favicon.ico HTTP/1.1" 404 85 "-" ... 195.195.195.12 - - [25/Oct/2016:15:14:09 -0400] "GET /favicon.ico HTTP/1.1" 404 85 "-" ...

How to get datetime without Django modifying time?
Django 1.9 / Postgres 9.4 - I have a model datetime field called date_ending. When I get the datetime with my_item.date_ending it gives me date and time that is different than what I see when I access the database directly. I set settings.py: TIME_ZONE = 'UTC' USE_I18N = False USE_L10N = False USE_TZ = False This should get django out of changing timezone stuff, correct? Basically I want Django to not touch timezones at all. Also, this might be something completey different... when I save a model with a datetime field and date field. The date is different thna dthe datetime. datetime_ = datetime.datetime.utcnow() datetime_date_ = datetime_.date() MyModel.objects.create( datetimefield=datetime_, datefield=datetime_date_, ).save() My database: datetimefield | datefield -------------------------------+----------------- 2016-11-04 18:23:18.407671-07 | 2016-11-05 ????

Django/DjangoTables2/Matplotlib - Displaying an MPLD3 graph and a Django Tables in a Django template?
I'm fairly new to Django, so bear with me please. I have made two different "apps": One that makes an MPLD3 graph and one that makes a DjangoTable. My original intention was to get both on the same page using a template. However, I do not know how to make it so that both are displayed on the same webpage. In my MPLD3 urls.py, I call a method called "display", which returns an HTTP response. In my DjangoTable urls.py, I call a method called "makeTable", which returns the following line of code: render(request, 'template.html', {'HEK_Observations': models.HEK_Observations.objects.filter(noaaNmbr=noaaNmbr)}) I'm confused because my understanding is that every webpage created calls a single methods to be run. I don't know how to call two methods in urls.py to create a single webpage that displayed both. Can somebody please explain to me the best way to accomplish this? For reference, here is the condensed version of my views.py for my Django Table: from django.shortcuts import render from interactive_table import models def makeTable(request): return render(request, 'template.html', {'HEK_Observations': models.HEK_Observations.objects.filter(noaaNmbr=noaaNmbr)}) Here is the condensed version of my views.py for my MPLD3 graph: Here is my urls.py for my Django Table: from django.conf.urls import url from . import views … -

How to get admin inline name?
I have 2 inlines with the same model. class UsersInlineAdmin(GenericTabularInline): model = CTSportsToCriterias class TeamsInlineAdmin(GenericTabularInline): model = CTSportsToCriterias class CTSportsToCriterias(models.Model): user_use = models.BooleanField(verbose_name=_('is available to users?'), default=False) team_use = models.BooleanField(verbose_name=_('is available to teams?'), default=False) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() content_object = GenericForeignKey() criteria_group = models.ForeignKey(CriteriaGroups, verbose_name=_('criteria group')) When I remove an item from one inline, django automatically removes this item from another inline, because according to the Django docs, the code: def save_formset(self, request, form, formset, change): for obj in formset.deleted_objects: ... provides model's object. Because in my case the model can have some options (user_use\ team_use), is it possible to get inline names in save_formset in order to do something like: if (inline_name == 'UsersInlineAdmin' and not obj.team_use) or \ (inline_name == 'TeamsInlineAdmin' and not obj.user_use): obj.delete() ? -

How should I implement corporate accounts on the web-site?
I have already ready WEBsite with user authentication. I need to implement corporate accounts functional, so that users of this account can go to the link corporate_account_name.main_domain.com and saw the same site as in main_domain.com only this version especially for them. How to do it and where to dig? (or at least a list of technologies, frameworks): One code for all subdomains? Create separate database for each subdomain? At the same time you need to access data from main_domain to all subdomains and vice versa (subdomain -> main_domain). It is likely that the code may need to update the long migration of the database data. It is necessary that in this case all the subdomains not froze until the updated one of the bases. The server on apache. This restart apache every time you create a business account is not possible. Corporate accounts creates on the web interface main_domain.com (automatically), like a standard user registration. Do not manually! It is desirable for django. -
Django Rest Framework ViewSets: Include arbitrary context content in Response
How does one initialize the Response() with additional arbitrary content across all ViewSet methods, without overriding each method individually? Use Case: I would like to include arbitrary content (in this case a Form object along with the serialized results in a Rest Framework ViewSet Response. I know that if I override an individual ViewSet method (such as list) this is easy enough: def list(): serializer = FooSerializer() context = { 'form': BarForm(), 'data': serializer.data } return Response(context) I also know that I can populate the serializer with additional context using the get_serializer_context() method here class FooSerializer(serializers.ModelSerializer): ... def get_serialzier_context(self): context = {'form': BarForm()} return context And that does indeed get passed to the serializer I also know that I can override the to_representation() method on the Serializer class, and use my arbitrary context to further manipulate serialized data at the instance level, but that's not what I want. I have also explored the use of the get_renderer_context() method as described here, but that hasn't borne fruit yet. I have even looked to the rest_framework/pagination.py code, as it injects 'previous', 'next', and 'count' attributes into the context: def get_paginated_response(self, data): return Response(OrderedDict([ ('count', self.page.paginator.count), ('next', self.get_next_link()), ('previous', self.get_previous_link()), ('results', data) ])) … -

Twitter api requests after social-auth Django
I am working on simple django project to show list of followers of logged in user. I have 'Log in with Twitter' button on my page. It works correctly, user is logged in and after auth it redirect to page with 'Welcome John Doe'.

Followers screen names: abc, microsoft,john21,bill21 Right now i am just showing logged user full name. Question: How can i quickly use logged user auth token and key to send API requests to get follower ids? Or what is the easiest way to send and receive info from API using already logged in user? Only way i did Twitter api handling before was using this code: import twitter api = twitter.Api(consumer_key='consumer_key', consumer_secret='consumer_secret', access_token_key='access_token', access_token_secret='access_token_secret') but right now i don't know how extract consumer key and consumer_secret since he's authorised.

Webpack: Loading Codesplit Chunks from S3 Using Django Storage
I am using django storages to serve my static files from s3, and am in the process of moving them all into a webpack bundle. This works well with django-webpack-loader which doesn't care where django finds the bundle. My problem is that when I start to define split points using require.ensure, the bundle attempts to download the chunk using a relative path, instead of the s3 bucket, because webpack's codesplitting feature is agnostic to django storage. Is there a way to inject custom logic for fetching the chunks on demand? I'm not above hard coding my s3 bundle address into the config file, but nothing I've tried so far has worked. -

Django Rest Framework ModelSerializers - Handling create and update
I have some models in my Django database. Each model is created or updated through the DRF API. As a result, I have serializers (for every model) that handle the create, update and partial_update on the models. A main part of the handling includes the following action: def handle(): if created: model.owner = request.user model.other_fields = other fields model.save() else: model.other_fields = other fields model.save() Additionally, I need to create log entries whenever a model is saved, with request.user. Log.objects.create(user=request.user, model=model, created=timezone.now()) I cannot use signals to create log entries, as the post_save signal does not have the request object. How should I handle this? Should I create a custom signal and send it every time I create or update a model? Should I call a function in serializer's create and update to log the model?
