Airbrake throwing error "pybrake - ERROR - strconv.ParseInt: parsing "None": invalid syntax"
I'm trying to use the Airbrake logger in a Django project following the steps described in https://github.com/airbrake/pybrake#django-integration. I've configured my LOGGING setting like so: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'handlers': { 'airbrake': { 'level': 'ERROR', 'class': 'pybrake.LoggingHandler', } }, 'loggers': { 'lucy_web': { 'handlers': ['airbrake'], 'level': 'ERROR', 'propagate': True, } } } Then, in a particular file in the lucy_web hierarchy called lucy_web/lib/session_recommendation.py, I have the following test function: import logging logger = logging.getLogger(__name__) def log_something(): logger.error("Logging something...") However, if I try to call this function from the Django shell, pybrake itself logs an error: strconv.ParseInt: parsing "None": invalid syntax Here is the full sequence of commands: (venv) Kurts-MacBook-Pro-2:lucy-web kurtpeek$ python manage.py shell Python 3.6.4 (v3.6.4:d48ecebad5, Dec 18 2017, 21:07:28) Type 'copyright', 'credits' or 'license' for more information IPython 6.3.1 -- An enhanced Interactive Python.

how to get only results in many to many relationship in django
I have the following relationships: class Customer(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) class Post(models.Model): customer = models.ForeignKey('common.Customer', mentions = models.ManyToManyField('common.Customer',related_name='mentions') I want to get all of the users that are mentioned in a post. I'm thinking something like this: customer = Customer.objects.get(user=request.user) posts = Post.objects.filter(mentions__in=customer).order_by('-created_at') Is this close to what I'm trying to accomplish? -
How to remove a form from formset
views.py formset = ComparisonScoreFormSet(initial=[ {'comparison': comparison} for comparison in Comparison.objects.all() ]) I initialized a formset with initial values.

How to use Airbrake's pybrake Django integration?
I'm trying to apply the Django integration steps described for pybrake, a Python exception notifier for Airbrake. The Django project contains several apps, one of which is called lucy_web. In my setttings, I've defined the AIRBRAKE setting like so: AIRBRAKE = dict( project_id=os.getenv('AIRBRAKE_API_KEY'), project_key=os.getenv('AIRBRAKE_PROJECT_ID'), environment=os.getenv('AIRBRAKE_ENVIRONMENT', default='production'), root_directory=os.path.dirname(os.getcwd())) The LOGGING setting is: LOGGING = { 'version': 1, 'disable_existing_loggers': False, 'filters': { 'require_debug_true': { '()': 'django.utils.log.RequireDebugTrue', } }, 'handlers': { 'console': { 'level': os.environ.get('LOG_LEVEL', 'ERROR'), 'filters': ['require_debug_true'], 'class': 'logging.StreamHandler', }, 'airbrake': { 'level': 'ERROR', 'class': 'pybrake.LoggingHandler', } }, 'loggers': { 'django.db.backends': { 'level': os.environ.get('LOG_LEVEL', 'ERROR'), 'handlers': ['console'], }, 'lucy_web': { 'handlers': ['airbrake'], 'level': 'ERROR', 'propagate': True, } } } Note that I've replaced the key 'app' in the README by 'lucy_web', the name of one of the apps in the project. Now, as I understand from Python's logging documentation (https://docs.python.org/3/library/logging.html), any Logger object with a name like 'lucy_web.foo.bar' should propagate to the 'lucy_web' logger and get handled by its handler, which is defined above to be the pybrake.LoggingHandler. To test this, I tried the following test in lucy_web/tests/test_airbrake.py: import os import logging import pybrake from django.test import SimpleTestCase logger = logging.getLogger(__name__) class AirbrakeTest(SimpleTestCase): def test_1(self): notifier = pybrake.Notifier( project_id=os.getenv('AIRBRAKE_PROJECT_ID'), project_key=os.getenv('AIRBRAKE_PROJECT_KEY'), environment='production', root_directory=os.path.dirname(os.getcwd())) … -
Restrict access to a part of a template to users that is part of a group using Class based views. Django 2.0
I want to restrict users in certain groups from accessing parts of the HTML template. I have a class based view that looks like this: Views.py class PostListView(ListView): model = BlogPost paginate_by = 10 template_name = 'main/mysite.html' With function based views I can restrict access on a template based on someones group using request.user.groups.filter(name='GROUP_NAME').exists() from In Django, how do I check if a user is in a certain group? I tried changing my view.py and HTML template like this: views.py class PostListView(ListView): model = BlogPost paginate_by = 10 template_name = 'main/mysite.html' def dispatch(self, request): in_group = request.user.groups.filter(name='GROUP_NAME').exists() return in_group HTML TEMPLATE .... {% if in_group %} some code here shows up if user belong to group {% endif %} .... This will give me the correct display when the user is not a member of the group, but when they are a member of the correct group I get an attribution error: Exception Type: AttributeError at /mysite Exception Value: 'bool' object has no attribute 'get' -
Django many-to-many relationship doesn't return set object

CircleCI not picking up environment variable defined in run step?
I'm trying to run CircleCI tests for a Django project in which the manage.py determines the version of settings.py to apply (development.py, staging.py, or production.py) from an environment variable, ENV_ROLE. Previously, ENV_ROLE was set to default to development if not defined, but I'm in the process of changing it so that Django instead throws an ImproperlyConfigured error if it is not defined. In order to make the tests pass, I need to define the ENV_ROLE environment variable in our CircleCI test environment. Following https://circleci.com/docs/2.0/env-vars/#setting-an-environment-variable-in-a-step, I've added the following to the run step: - run: environment: ENV_ROLE: development However, I am still getting this error from CircleCI: #!/bin/bash -eo pipefail cd lucy-web source venv/bin/activate python manage.py compilescss --verbosity 0 python manage.py collectstatic --clear --no-input --verbosity 0 flake8 python manage.py test Traceback (most recent call last): File "/root/lucy/lucy_web/lucy-web/env.py", line 5, in <module> ENV_ROLE = os.environ['ENV_ROLE'] File "/usr/local/lib/python3.6/os.py", line 669, in __getitem__ raise KeyError(key) from None KeyError: 'ENV_ROLE' During handling of the above exception, another exception occurred: Traceback (most recent call last): File "manage.py", line 4, in <module> from env import ENV_ROLE File "/root/lucy/lucy_web/lucy-web/env.py", line 8, in <module> "No 'ENV_ROLE' environment variable is defined.

Django runserver doesn't respond on browser despite port on 'LISTEN'
I have stumbled on this issue that I have no clue how to resolve. When I run python manage.py runserver, I open http://127.0.0.1:8000/ on my browser, which shows the following result: enter image description here I tried all the solutions proposed on StackOverflow for similar problems. I tried running python manage.py runserver 0.0.0.0:8000 but it didn't change anything. I checked my port was listening using sudo nmap -sT -O localhost and the result was this: enter image description here but when running netstat -anv, I get this: enter image description here I even tried killing it using sudo lsof -t -i tcp:80 then kill -9 xxxx (with xxx being the pid). All my proxies are deactivated (see below) so I have no clue what's going. enter image description here I have been trying to resolve this issue for the past two days. I am a beginner in Django and would like to know what is going on. I have been reading all threads on the website but haven't found a solution that suits me. I am looking forward to your answer.

Django migrations file missing
I have a Django project where I have an app 'create'.The 'showmigrations' are correct and app works fine. But I could not find the latest 0006_XXXX.py file to add and push to subversion(GIT). I tried faking back to the previous migration(0005_XXXX) and then 'migrate' to latest migration '0006_XXXX'. I can see 'Applying create.0006_XXXXX... OK' message in output. But the 0006_XXXX.py file is not getting created in 'create/migrations' directory. Any idea why the file is not created? -
Djagno: upload csv file and stays in memory
I'm trying to build a web app using Django where the user will upload some csv file, possibly a big one. Then the code will clean the file for bad data and then user can use it to make queries with clean data. Now I believe whenever a user will make a query, the whole code will run again which means it will start cleaning again and so on. Question: Is there any way that once the csv data in clean, it stays in memory and user can make queries to that clean data? import pandas as pd def converter(num): try: return float(num) except ValueError: try: num = num.replace("-", '0.0').replace(',', '') return float(num) except ValueError: return np.nan def get_clean_data(request): # Read the data from csv file: df = pd.read_csv("data.csv") # Clean the data and send JSON response df['month'] = df['month'].str.split("-", expand=True)[1] df[df.columns[8:]] = df[df.columns[8:]].astype(str).applymap(converter) selected_year = df[df["Departure Datetime: Year (YYYY)"] == 2015] data_for_user = (selected_year.groupby( by="route").sum().sort_values(by="revenue").to_json() return JsonResponse(data_for_user, safe=False) -

Django template language unpacking a dict
I have a dictionary passed (as part of another object) to the django template language. The object, called 'poll' has attributes self.text and self.votes, where the former is a string, and the latter is a dict. The dict, looks like this: {'a1': 45.92422502870264, 'a2': 53.50172215843857} I am trying to list each label, with its accompanying number, using the following: {% for l, x in poll.votes %} <p>{{ l }} {{ x }}</p> {% endfor %} Django responds with Exception Type: ValueError Exception Value: Need 2 values to unpack in for loop; got 3. I tried .iteritems - The docs explain that .iteritems is not the correct way to do this, but they don't explain what the correct way is. -
Django multiple database error
I have one Django project that contains a database with data that I need for another database. So, I found some code online and start using it. However, even the code is wrong or I’m doing it wrong. I’m guessing the latter. The database “reservation” is the “external’ database. I made models for those tables in the Django project which is going to import the data. I also give class Meta in the other database in “reservation”. The migration gave no errors and I did do: python manage.py migrate --database=reservation. I tried to get data from the “external’ database, however I keep getting the error: “no such table: res_room”. This is my settings file: DATABASES = { 'default': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'), }, 'reservation': { 'ENGINE': 'django.db.backends.sqlite3', 'NAME': os.path.join(RES_DIR, 'db.sqlite3'), } } #Define the database manager to setup the various projects DATABASE_ROUTERS = ['app.router.DatabaseAppsRouter'] DATABASE_APPS_MAPPING = {'res': 'reservation'} This is my router: from django.conf import settings class DatabaseAppsRouter(object): def db_for_read(self, model, **hints): print("Facebook") print(model) """"Point all read operations to the specific database.""" if model._meta.app_label in settings.DATABASE_APPS_MAPPING: return settings.DATABASE_APPS_MAPPING[model._meta.app_label] return None def db_for_write(self, model, **hints): """Point all write operations to the specific database.""" if model._meta.app_label in settings.DATABASE_APPS_MAPPING: return settings.DATABASE_APPS_MAPPING[model._meta.app_label] … -
Python Relative Imports "Above Top Level"
This is my directory structure src\ dirCode\ dirSubCode\ test.py Django\ DjangoApp\ Home\ views.py From within views.py I'm trying to import a class (let's call it Main) from test.py. The line in test.py is simply from dirCode.dirSubCode.test import Main and I'm getting a ModuleNotFoundError when I try to run the server. I printed out the os.sys.path and the second entry points to 'src\' while the first entry is simply ''. Since this is not the only app from where I'm going to need to call "external" code I'm trying to avoid hard-coding sys.path.insert(0,'path\to\src\dirCode\dirSubCode\') if that would even work. I've tried looking through documentation, looking at other StackOverflow questions, etc. but I'm at a loss as to how to do this. I've tried going into the src\Django\DjangoApp\Home directory and just running a python console and simply trying to import the class but it's giving me the same error. One odd development that I'm running into is that when I try to run it from the Anaconda Prompt (yes, I'm running Windows) it doesn't work but when I run the file in PyCharm it does work. If that helps provide some insight as to what might be going on I'd appreciate the help. -

Using Ajax change state of a clicked button
I am building a page in a Django project which has multiple comments each of which can be liked/unliked with a button next to the text. So the page has multiple like/unlike buttons. The buttons display fine when the page is loaded, and I can use Ajax to send data to Django and update my database which works fine, and I can return data back to the Ajax success function. What I can't work out is - how can I update the status of the actual button which was clicked. I am able to update the status of all of the buttons together on the page as per the code below (pointless I know!), but can't see how I reference the clicked button. I've tried passing and then returning the button id which I can display in an alert, but not sure if this is what I should be using or where I go from here?

Django on_delete SET_NULL not working
I have models set up like so: class User email = models.EmailField(unique=True) class Store owner = models.ForeignKey(User, null=True, on_delete=models.SET_NULL) My expectation is that the on_delete=models.SET_NULL means that if a User is deleted, the Store will not be deleted. However, this suspicion is not confirmed by my tests (see below). Can someone help explain my misunderstanding? And yes, I did run migrations before doing my tests! This first test tests whether the deletion of a Store leads to the deletion of a User, which should not be the case. This test passes as expected. def test_delete_store(self): self.store.delete() with self.assertRaises(Store.DoesNotExist): Store.objects.get(pk=self.store.pk) self.assertEqual(User.objects.get(pk=self.user.pk), self.user) The following test tests whether the deletion of a user leads to the deletion of the store.
