RawPostDataException: You cannot access body after reading from request's data stream
I am hosting a site on Google Cloud and I got everything to work beautifully and then all of the sudden I start getting this error.. 01:16:22.222 Internal Server Error: /api/v1/auth/login/ (/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/core/handlers/exception.py:124) Traceback (most recent call last): File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/core/handlers/exception.py", line 39, in inner response = get_response(request) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/core/handlers/base.py", line 249, in _legacy_get_response response = self._get_response(request) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/core/handlers/base.py", line 187, in _get_response response = self.process_exception_by_middleware(e, request) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/core/handlers/base.py", line 185, in _get_response response = wrapped_callback(request, *callback_args, **callback_kwargs) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/views/decorators/csrf.py", line 58, in wrapped_view return view_func(*args, **kwargs) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/views/generic/base.py", line 68, in view return self.dispatch(request, *args, **kwargs) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/rest_framework/views.py", line 474, in dispatch response = self.handle_exception(exc) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/rest_framework/views.py", line 434, in handle_exception self.raise_uncaught_exception(exc) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/rest_framework/views.py", line 471, in dispatch response = handler(request, *args, **kwargs) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/authentication/views.py", line 42, in post data = json.loads(request.body) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/rest_framework/request.py", line 359, in __getattribute__ return getattr(self._request, attr) File "/base/data/home/apps/s~crs-portal/1.395605052160854207/lib/django/http/request.py", line 263, in body raise RawPostDataException("You cannot access body after reading from request's data stream") RawPostDataException: You cannot access body after reading from request's data stream I have no clue what this means, and endless googling has not solved my case in anyway..

django - resizing horizontal filter for group admin page
I'm trying to resize the horitontal filter for default group admin page because it is too small. Here is what I've tried: admin.py: class GroupAdmin(admin.ModelAdmin): filter_horizontal = ('permissions',) class Media: js = ('js/group_admin.js',) admin.site.unregister(Group) admin.site.register(Group, GroupAdmin) group_admin.js: $(function() { $("#id_permissions_from").css("height", 600); $("#id_permissions_from").css("overflow", "scroll"); $("#id_permissions_to").css("height", 600); $("#id_permissions_to").css("overflow", "scroll"); }) It's not resizing and is not showing any javascript error. If I run the javascript above in the console it works fine; so there must be something wrong with the order of javascripts getting loaded. I'm using django 1.8. Any ideas? -
Submenu refuses to open on click. Why?
I'm trying to have a left side navigation bar where by default categories are listed and upon clicking on a category, the subcategories are shown under it (in a sort of expanding sub-menu). I'm working in Django and relevant portions of my code are below. When I include the JS code, none of the links on the page work and when I exclude it, all the subcategories for all categories are shown by default. I need only categories to be shown by default and upon clicking on any, the respective subcategories be shown. What am I missing here? JS CODE: at the bottom of the page, loaded after the footer: {% block theme_script %} <script src="{% static "pinax/js/theme.js" %}"></script> <script> $(function(){ $(".nav-collapse88").hide(); $(".nav-collapse89 a").click(function(e){ e.preventDefault(); $(".nav-collapse88", $(this).parent()).slideToggle(); }); }) </script> {% endblock %} My HTML: <ul class="catindexlist catlistcat nav-collapse89"> {% for category in catindexlisted %} <div class="catindexlistitem"><li class="category-name" style="font-weight:600;padding-right:20px;"><a href="">{{category.name}}</a></li></div> <div class="nav-collapse88"> <ul style="padding:0px;"> {% for forum in category|forumindexlistbycat %} <div class="catlistforum"><li style="padding-right:10px;"><a href="{{ forum.get_absolute_url }}">{{forum.name}}</a></li></div> {% endfor %} </ul> </div> {% endfor %} </ul> All who answer will win a magical Pony!

Django does session.flush() expire the database session entry?
According to the Django documentation here request.session.flush() Deletes the current session data from the session and deletes the session cookie. (django.contrib.auth.logout() function calls it) But does it also automatically expire the session entry inside the database table? Because if it doesnt, I think that might cause an unnecessary build up of non-usable but non-expired sessions inside the table. -
PYTHONPATH - pyvenv & django
I created a virtual environment using pyvenv at ~/Developer/environments/eg. I printed out the sys.path and I'm concerned as to why the lib folder for the environment is listed after the global lib folder. Shouldn't pyvenv be putting it before it so that it doesn't touch the global one? >>> import sys >>> print(*sys.path,sep='\n') # this one makes sense because the 1st eg is the pyvenv, the second eg is the django workspace /Users/myself/Developer/environments/eg/eg /usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/python35.zip /usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/python3.5 /usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/python3.5/plat-darwin /usr/local/Cellar/python3/3.5.0/Frameworks/Python.framework/Versions/3.5/lib/python3.5/lib-dynload # shouldn't this one be above the previous ones? /Users/myself/Developer/environments/eg/lib/python3.5/site-packages If I'm importing an app or package, why would I trust it to find my environment package before the global one if it's listed after? -

Is it possible to submit a form with angular and with html
I need to authenticate my django app as well as the angular app that is used within it. The service backend uses django rest framework OAuth. I have tried sharing session variables but they seem to be different sessions. It seems the only way is to create a login form that kicks off an angular ng-submit in addition to regular form submit which will authenticate the django app. Are there any examples of this available? Is this even a good idea? -

Django dumpdata uses the display value of a field where choices is set instead of the smallintfield key
I have an abstract object which is defined as Person object. I have several descendants. On one descendant Staff, I have a smallintfield (designation) that has a choices set to a tuple defined as: DESIGNATION_CHOICES = ( (MEDTECH, 'Medical Technologist'), (PATHOLOGIST, 'Pathologist'), ) Where MEDTECH and PATHOLOGIST are numeric constants. When I do a ./manage.py dumpdata on the app, the designation field will get the value 'Medical Technologist' instead of the key value MEDTECH. Does anyone have any idea how I can resolve this? -
How to configure Visual Studio Code to debug Django app in a virtualenv?
I would like to have possibility to do a debugging of Django application in Visual Studio Code. I have a virtualenv, made a change in launch.json file that look like this: { "name": "Django", "type": "python", "request": "launch", "stopOnEntry": true, "pythonPath": "${workspaceRoot}/.venv/bin/python2.7", "program": "${workspaceRoot}/mysite/manage.py", "args": [ "runserver" ], "debugOptions": [ "WaitOnAbnormalExit", "WaitOnNormalExit", "DjangoDebugging", "RedirectOutput" ] }, put several break points in the code and run it. Unfortunately, the execution is not stopped on the line with break points. I tried the same without virtualenv and everything worked perfectly. Please, point out what I am doing wrong here. -
How to add change-related and add-related widgets on the right of Grappelli autocomplete widget in Django admin?
The default widget for the ForeignKey model field looks like a <select> html element with change-related (a pencil) and add-related (a plus sign) buttons on the right. How can I instead use Grappelli autocomplete widget and still have a pencil and a plus sign on the right of the widget? -
Server rendering in python/ruby/php then attach react.js in client
I'd like to try react.js. Most examples seem to suggest server api + reactjs rendering or server rendering via node/reactjs + reactjs rendering on client I'd like to have two templates, one server and one client because I think maintaining node+reactjs on server is a hassle and cause performance degrade. If I render html on server with jinja2 (or whatever server template language other than reactjs), would it be possible to attach reactjs component to the rendered html? Doesn't react add special id and key attributes to divs that are hard to create with jinja2 (or any template language) ? -
Gunicorn, no module named 'myproject
I'm installing a previously built website on a new server. I'm not the original developer. I've used Gunicorn + nginx in the past to keep the app alive (basically following this tutorial), but am having problems with it here.

How to translate docker-compose.yml to Dockerrun.aws.json for Django
I am following the instructions at https://docs.docker.com/compose/django/ to get a basic dockerized django app going. I am able to run it locally without a problem but I am having trouble to deploy it to AWS using Elastic Beanstalk. After reading here, I figured that I need to translate docker-compose.yml into Dockerrun.aws.json for it to work. The original docker-compose.yml is version: '2' services: db: image: postgres web: build: . command: python manage.py runserver 0.0.0.0:8000 volumes: - .:/code ports: - "8000:8000" depends_on: - db and here is what I translated so far { "AWSEBDockerrunVersion": 2, "volumes": [ { "name": "db" }, { "name": "web" } ], "containerDefinitions": [ { "name": "db", "image": "postgres", "essential": true, "memory": 256, "mountPoints": [ { "sourceVolume": "db" "containerPath": "/var/app/current/db" } ] }, { "name": "web", "image": "web", "essential": true, "memory": 256, "mountPoints": [ { "sourceVolume": "web" "containerPath": "/var/app/current/web" } ], "portMappings": [ { "hostPort": 8000, "containerPort": 8000 } ], "links": [ "db" ], "command": "python manage.py runserver 0.0.0.0:8000" } ] } but it's not working.

how to get session or cookie value set in django, php, ruby in angular?
I am trying to get a session and/or cookie value I set in django (although I don't see this being different across other languages like php or ruby).

How can I select all two-row couples that match on a field in django?
I'm working with latest Django version and fail at creating a join filter, selecting two primary keys of the same table, using value equality on a field in that model. I have a table called Model, and it contains a field called Data. Each Model is associated with a File, similar to the following: class Model(models.Model): file = models.ForeignKey(File, related_name='models') data = models.TextField() I would like to implement a function that receives two File.ids: source_file and target_file. The function should return a list of two-tuples of two Model.ids: source_model and target_model. The first Model.id should be related to the first file (source_file) and the second Model.id should be related to the second file (target_file). The two Model objects are required to have the same value in Model.data. If there's a source_id without a target_id or vice-versa, they should be omitted from the returned list. For exmple, lets say I have the following Model table: | id | file_id | data | |----|---------|------| | 10 | 1 | a | | 11 | 2 | a | | 12 | 3 | a | | 13 | 1 | b | | 14 | 2 | c | | 15 | … -
Django: 400 Error with Debug=False and ALLOWED_HOSTS=["*"]
I'm trying to run a relatively simple Django server on python 3.5.3 on an Ubuntu DigitalOcean droplet. I'm using a Gunicorn server with nginx. The server runs fine when DEBUG=True in settings.py. But when I set it to False, I get a 400 error when trying to visit the page. I tried setting ALLOWED_HOSTS to ['*'], but I still get the same error. I've looked on a lot of forums and many questions on SO but none of the solutions have worked. -

Default instance for Django model

Django-channels fails on Travis-CI

Setting up a result backend (rpc) with Celery in Django
I am attempting to get a result backend working on my local machine for a project I'm working on but I am running into an issue. Currently I am trying to create a queue system in order for my lab to create cases. This is to prevent duplicate sequence numbers from being used. I am already using Celery for our printing so I figured I would create a new Celery queue and use that to handle the case. The front-end also needs to get the results of the case creations to display the case number that was created. http://docs.celeryproject.org/en/latest/getting-started/first-steps-with-celery.html#rabbitmq I was following the above tutorial on getting my Celery configured.

Django psql full text search not matching un-stemmed word
I'm running Django 1.10.1 against Postgres 9.4. My staging server and dev environments have psql servers at version 9.4.9 and production is an RDS instance at 9.4.7. It seems like my SearchVectorField is not storing the search configuration given in production, though it is in staging and dev, and it seems to be either a version thing (unlikely, given the version difference and that it also worked on 9.3 in staging/dev) or the fact that production is on RDS instead of local on the server. I'm using a custom configuration for full-text search which looks like this: Token | Dictionaries -----------------+----------------------- asciihword | english_stem asciiword | english_stem email | simple file | simple float | simple host | simple hword | unaccent,english_stem hword_asciipart | english_stem hword_numpart | simple hword_part | unaccent,english_stem int | simple numhword | simple numword | simple sfloat | simple uint | simple url | simple url_path | simple version | simple word | unaccent,english_stem Unaccent is installed in both environments, and works in both environments. I'm storing the search data in a django.contrib.postgres.search.SearchVectorField on my Writer model. That column is updated with the following search vector: (SearchVector('first_name', 'last_name', 'display_name', config='unaccent', weight='A') + SearchVector('raw_search_data', config='unaccent', weight='B')) And, …
