Where can I get a mod_wsgi.so file?
I've spent the past 3 days trying to install mod_wsgi. After finding out that it was a more complex process on Windows, I decided to do it with Linux, but I still haven't figured out how to install it into my Apache/Xampp server because I can't find any .so files in the latest release for mod_wsgi. My httpd.conf file is already configured and ready to load the module but for obvious reasons doing sudo /opt/lampp/lampp start yields Starting XAMPP for Linux 5.6.30-0... XAMPP: Starting Apache...fail. httpd: Syntax error on line 523 of /opt/lampp/etc/httpd.conf: Syntax error on line 11 of /opt/lampp/apache2/conf/httpd.conf: Cannot load /usr/lib/apache2/modules/mod_wsgi.so into server: /usr/lib/apache2/module /mod_wsgi.so: cannot open shared object file: No such file or directory XAMPP: Starting MySQL...ok. because there's no file there. So where do I actually get said file? I've seen some of them on older websites, but I'm reluctant to use them because of compatibility issues or those versions of the module having less features and fixes. -
How to annotate a distinct Count over multiple relationships in Django?
Given a model that has more than one kind of connection to a related model (I will call the "parent" model), how could I annotate a queryset with a count of parent model objects that are linked through either connection without counting duplicates? Example model definitions Consider an Article model that has 2 links to a parent Publication model that are very similar in meaning. from django.db import models class Publication(models.Model): pass class Article(models.Model): publication = models.ForeignKey(Publication, related_name='publications') owner = models.ForeignKey(Publication, related_name='owned_articles') Objective I want to serve a page that is a list of publications. A business requirement is that the number of articles that the publication wishes to take credit for are shown (these publications prefer a generous metric for counting). An article is considered part of the organization if either the "owner" or "publication" field points to it, but no articles should be counted more than once for a single publication. An article may be included in the count of 2 publications if publication points to a different object than owner. I don't want to execute a query for every publication in the list. The problem with Count annotations here Publication.objects.annotate(Count('publications'), Count('owned_articles')) would be trivial. Then I will … -
Using ajax in django to update image with matplotlib

Django template tag inside HTML input tag (value attribute)
Is there any way for template tags of the {% %} sort to work in the <input type="submit"> HTML tag? For instance, imagine the variable text contains You're cool :-), and I have a custom template tag that turns :-) into the corresponding custom emoji I've designed. Then, the following wouldn't work, would it: <input type="submit" name="text" value="{% emoticons %}{{ text }}{% endemoticons %}"> I understand I can also use <button type="submit" name="text">{% emoticons %}{{ text }}{% endemoticons %}</button>, but a button fundamentally doesn't overflow elegantly to the next line like regular text does, hence I'm trying to avoid it. Anyone got a neat workaround to this? Much appreciated. -
Django, how to pass variable to exception middleware?

django runserver startup using local settings when production was identified in .env file
I created a new project with cookiecutter django. I set the environment variable DJANGO_READ_DOT_ENV_FILE=True (setting it to False also causes the .env file to be read btw. I think that python assumes that the environment variable of True is a string not bool). In the .env file there is the following line: DJANGO_SETTINGS_MODULE=config.settings.production When I run python manage.py runserver I get the following output: Loading : /home/bucket/src/b2b/.env The .env file has been loaded.

How to continue testing/adding to django project after deployment

Wagtail CMS Snippet Model Objects Based on Boolean Object
I am using Wagtail CMS for a local restaurants new site and Snippets for creating their menu items. They, like many restaurants, offer similar items on lunch and dinner menus, but typically at different price points. I've created a simple model for them to add menu items and two boolean fields (lunch, dinner). Instead of offering all the fields for every menu item inputed, I'd like to do display panels based on the menu selected, i.e. if lunch == True display these panels... Below are my model Snippets; any help is greatly appreciated. Thank you.

Django cannot insert duplicate key value NULL
I need to allow NULL in enc_id, but if values are not null, I need those values to be unique.

I've recreated my DB just in case and it still raises the integrity error. I'm running Django 1.10 and MS SQL Server 10. Any ideas? -
Getting a Django project up and running on AWS
I am very new to web development in general, even though I have some background in computer science. I have been having an issue getting my (very basic) Django project running on a webpage online (non-locally). I am using Amazon Web Services(AWS) with an EC2 instance running Ubuntu. I am trying to get the Django project running with a combination of nginx, supervisor, and gunicorn. I tried following this tutorial, but ran into issues when binding gunicorn to my IP address (specifically, I run into an invalid address error and I am not sure what exactly my AWS IP address is) + when running nginx I would get a 502 gateway error. I feel like this is a relatively simple task that I am struggling an immense amount with. Any help would be appreciated! -
django error on migration: "There is no unique constraint matching given keys for referenced table
So I have seen that a lot of these kinds of questions have popped up (few answered) and none in a Django aspect that I saw. I am confused why I am getting the error, I am guessing i am missing something on my field decorator or what not in my model definition. Here are the two models... (one abbreviated).

supervisord refuses to run command as user (always runs as root)
For some reason, supervisor refuses to start the command as user - it always runs it as root - and this is an issue for me since I am activating a virtualenv and running commands specific to that particulat virtualenv. So, my conf looks like so: [program:site] command = /home/some/virtual/env/dir/run/start.sh user = foo stdout_logfile = /home/some/etc/supervisor/logs/logging.log redirect_stderr = true environment=LANG=en_US.UTF-8,LC_ALL=en_US.UTF-8 stopsignal=KILL killasgroup=true autostart=true start.sh looks like so: #!/bin/bash cd source /home/foo/some/virtual/env/bin/activate cd /home/foo/.ve/dj_solar/dj_solar/ SOCKFILE01=/home/some/etc/supervisor/site.sock exec /home/some/virtual/env/bin/gunicorn -b unix:$SOCKFILE01 site.wsgi:application -w 2 -k gevent --worker-connections=2000 exit 0 when I inspect the log, I see: start.sh: line 2: cd: /root: Permission denied which means this is still running as root. I am totally baffled by this. I start supervisor as root. The even weirder part is that the above code works totally fine on my local machine, but shows me the above log on a server. I have run out of ideas... :(( -
Binding a FormSet in a ModelForm in Django
I'm writing an app for managing health care plans which manages things like Allergies, Diabetes, etc. I have a form that I can successfully create new records with, but I'm running into problems when it comes to updating that data. My problem is that I'm not sure how to bind my formsets to the saved data when the UpdateView is opened. My current strategy is to follow the answer found here, but I'm not sure if it's the right one in this context.

Django migration breaks with Postgres 9.6
I have upgraded version of Postgres to 9.6. It doesn't accept UTC as value for timezone and throws following error. ERROR: invalid value for parameter "TimeZone": "UTC" Django's (1.9.2) python manage.py migrate fails as it executes SET TIME ZONE 'UTC'; There is a thread about this which says restarting postgres instance will resolve, but it does not.

Connect django-user-accounts to already existing users
I've installed and added django-user-accounts to an existing project as wanted an easy way to set up things like user account pages and the ability to request a new password etc. After setting it up there now is a new section in the admin panel called "ACCOUNTS".

Django find relationship "route" between two Vertexes in a Network
This is mostly a logical question, but the context is done in Django. In our Database we have Vertex and Line Classes, these form a (neural)network, but it is unordered and I can't change it, it's a Legacy Database class Vertex(models.Model) code = models.AutoField(primary_key=True) lines = models.ManyToManyField('Line', through='Vertex_Line') class Line(models.Model) code = models.AutoField(primary_key=True) class Vertex_Line(models.Model) line = models.ForeignKey(Line, on_delete=models.CASCADE) vertex = models.ForeignKey(Vertex, on_delete=models.CASCADE) Now, in the application, the user will be able to visually select TWO vertexes (the green circles below) The javascript will then send the pk of these two Vertexes to Django, and it has to find the Line classes that satisfy a route between them, in this case, the following 4 red Lines : Business Logic: A Vertex can have 1-4 Lines related to it A Line can have 1-2 Vertexes related to it There will only be one possible route between two Vertexes What I have so far: I understand that the answer probably includes recursion The path must be found by trying every path from one Vertex untill the other is find, it can't be directly found Since there are four and three-way junctions, all the routes being tried must be saved throughout the recursion(unsure … -
What is the correct http verb for Django REST partial_update
Im trying to perform partial update in DRF using angular $http. In my DRF model viewset i override the partial_update function (server side). def partial_update(self, request, pk=None): instance = self.get_object() serializer = self.serializer_class(instance, data=request.data, partial=True) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_200_OK) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) In the client side angular handle the user request. $http.patch('/api/my_viewset_url/1', data); But i got this response Method Not Allowed (PATCH): /api/my_viewset_url/1 When using $http.get() request with DRF model viewset list(self, request) it works well for getting a list same goes for $http.post() with def create(self, request) for creating object and $http.put() with def update(self, request) for updating object. What's wrong? or what is the correct http verb for partial_update in DRF model viewset -

Django exception middleware: TypeError: object() takes no parameters

Installing TinyMCE on Django (And using it on forms)
Hi Im trying to install TinyMCE on a Django project and Im totally lost about static files, MEDIA, and the world itself. I want to use TinyMCE in one of the fields of a form: class MovieForm(forms.ModelForm): class Meta: model = Movie fields = ['title', 'language', 'description'] widgets = { 'languages': forms.SelectMultiple(), 'description': TinyMCE({'cols':80, 'rows':30}), } I installed django-tinymce pip install django-tinymce Then I added it to the installed apps INSTALLED_APPS = ( ... 'tinymce', ... ) And then added the urls in my project urls.py urlpatterns = patterns('', ... (r'^tinymce/', include('tinymce.urls')), ... ) Great. So what do I do next? I read the Configuration part on http://django-tinymce.readthedocs.io/en/latest/installation.html#configuration but I dont get it. Should I add TINYMCE_JS_URL = os.path.join(MEDIA_URL, "path/to/tiny_mce/tiny_mce.js") to my project settings.py? Where do I put tiny_mce.js? Should I configure MEDIA_URL somewhere?

Multi-tenant issue using django-rest-framework
We have an issue to make a multi-tenancy SaaS application using Django and django-rest-framework. We would like to route to the correct database according to the url, and using django-rest-framework serializers. But with django-rest-framework, we cannot specify the database we want to save to with serializers. We are able to request data by overriding the get_queryset method, and with the using(<database>) function. class SomeSerializer(serializers.ModelSerializer): def get_queryset(self): return SomeModel.objects.using(self.database) If we want to save an instance to a custom database, we cannot use ModelSerializer, we have to write each serializer using the Serializer class. We can make a pull request to add the option to django-rest-framework Multiple databases support #65 - django-rest-framework Or, we can do something similar to this snippet : Database Routing by URL, it's quite old (2010) but still working. But we are not very comfortable with the idea of using the local thread to transfer variables. How do we do this properly in 2017 ? Are there other options ? -
