Heroku deployment missing files from git
I'm having problems with a deployment in Heroku. My app uses Django and React so when I deploy the server runs Webpack to concatenate all the javascript. The deploy fails because it says there is a file missing, if I run webpack locally with the same version it runs perfectly. The thing is that the file is in the repository, if I clone the repo from Github the file is there and I can make it run. I tried both deploying from my local repo and straight from Github. This is not the first time I've deployed this app to Heroku and it worked before so I know the configuration is not a problem. The file that heroku is missing has been created after the last deploy I'm quite inexperienced with Heroku so I will be thankful for a way to investigate this problem. Thanks! -
Docker in Django 2.0 and Postgresql not working (Windows 10 Home)
I've been following this tutorial and I made some modifications, because I'm using virtualenv instead of pipenv, so I'll be using a requirements.txt file to manage the dependencies. https://wsvincent.com/django-docker-postgresql/ Dockerfile: # Pull base image FROM python:3.6-slim # Set environment varibles ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 # Set work directory RUN mkdir /code WORKDIR /code # Install dependencies RUN pip install --upgrade pip ADD requirements.txt /code/ RUN pip install -r requirements.txt # Add project ADD . /code/ docker-compose.yml: version: '3.6' services: db: image: postgres:10.1-alpine # volumes: # - postgres_data:/var/lib/postgresql/data/ web: build: . # command: python /code/manage.py migrate --noinput command: python /code/manage.py runserver 0.0.0.0:8000 # volumes: # - .:/code ports: - 8000:8000 environment: - SECRET_KEY=changemeinprod depends_on: - db volumes: postgres_data: After running: (dfb_mb_docker) C:\Projects\dfb_mb_docker>docker-compose run web python /code/manage.py migrate --noinput I had this error: Starting dfbmbdocker_db_1 ... done python: can't open file '/code/manage.py': [Errno 2] No such file or directory That's why I commented out the volumes.

How to make ImageField returns relative path?
I don't know why, but my ImageFields return full URL pathes. I use this custom FileStorage: class ASCIIFileSystemStorage(FileSystemStorage): def get_valid_name(self, name): return str(uuid.uuid4()) + '.' + name.split('.')[-1] And simple ModelSerializers (from django rest framework) without overwriting smth. What can be the reason of those behaviour? I need relative URLs. -
When and where do I create configurable custom groups in Django without running in "no such table: auth_group" on startup?
I'm still learning and working on an existing Django app (v1.10.) for which I am trying to switch existing custom groups to making them dynamically configurable, so that the app can be used in different contexts. I have an ini file, which includes my dynamic groups: ; Custom groups and permission settings [platform_group_list] TEAM = policy_team LEAD = policy_team_lead [platform_group_value_list] TEAM = Policy Team Member LEAD = Policy Team Lead which I parse in settings.py: PLATFORM_GROUP_LIST = raw_parser.items("platform_group_list") PLATFORM_GROUP_VALUE_LIST = raw_parser._sections["platform_group_value_list"] The original app created groups and permissions inside migrations. I commented out the part there as it kept throwing errors regarding missing permissions and thought that maybe it would be better to do this in admin.py since this is where the groups "belong". So I have: # admin.py (removed custom permissions, not relevant atm) from django.contrib import admin from django.contrib.auth.admin import UserAdmin as BaseUserAdmin from django.contrib.contenttypes.models import ContentType from django.contrib.auth.models import Group, Permission, User from django.contrib.auth import models as auth_models from django.core.exceptions import ObjectDoesNotExist from django.conf import settings from django.utils.translation import ugettext as _ from account.models import SignupCodeResult from .models import UserConfig # BACKCOMPAT # add staff to the backcompat groups and vice versa, then remove the # backcompat … -

Get Django CMS plugin information from Haystack search results
My search results page needs to display information about the Plugins where the query was found, too. I found this question with a similar problem, but I don't only need the contents, I need to know stuff about the plugin - i.e. what's it called, where it is on the page and stuff. Basically I would like a reference to the plugin where the query was located, but I can only find information about the page and title. I haven't been able to find it anywhere on the SearchQuerySet object and in the vicinity - also coming up empty in the documentation for Haystack. Is it possible and how? Stack I'm using: Elasticsearch 2.4, django-haystack 2.8, aldryn-search 1.0 (for CMS indexing). -
Django debugger-tool - How to avoid duplicate querys in for loop in this case
thank you in advance for your answers. How can I avoid duplicating querys ?, if I go through only 6 products it takes 50ms (6 querys duplicated), but when I try to go through 7000 products it takes too long (7000 duplicated querys), there is some way of caching all the products so that you have to do a query every time we go through the for loop, or should go through the loop in another way.

Question mark not recognized with path function
I'm working on a django web app. I'm trying to implement a search field that would "communicate" with the url. I want from http://127.0.0.1:8000/contract/ that when I enter an id in the search field, it redirects me to http://127.0.0.1:8000/contract/id . The problem is that when using the search field, it redirects me to http://127.0.0.1:8000/contract/?search=id which is not really a problem. But when I try to define the urlpattern, it doesn't 'recognize' the question mark in the url. The consequence being that I can't access to the right template. urlpatterns = [ path('?search=<id_contract>/', app_views.view_contract), path('', app_views.contract, name='my_contract'), ] I see two possible solutions : either I would try to find a way to remove that question mark, but I haven't really found where to do it so I would much appreciate your help! Second option consists in using regex but what I've tried so far didn't work : re_path(r'.+\?.*'+'search'+'(?P<id_contract>)/$' Thank you for your help. -

How to send pk in header body of PUT request instead of changing the API end point url

In Django, how can I make session work if the view function has a csrf_exempt decoration?
I'm using Django as restful APIs and found that session doesn't work if a view has a csrf_exempt decoration.

However, if there isn't csrf_exempt, it works: def scorer_login(request): request.session['username'] = 'test_username' How can I fix it? -

django class-based view unexpected keyword argument
I had a legacy code: my url: url(r'^check_unique_username/(?P<field_value>(.*?){1,150})/$', auth.views.check_unique_username, name='check_unique_username'), my view: def check_unique_username(request, field_value): return HttpResponse(check_unique_filed_value(request, "username", field_value)) which works perfectly with localhost:8000/check_unique_username/myusername but now I want to make it class-based: url: url(r'^check_unique_username/(?P<field_value>(.*?){1,150})/$', auth.views.CheckUniqueUsername.as_view(), name='check_unique_username'), view: class CheckUniqueUsername(APIView): def get(self): return HttpResponse(CheckUniqueFieldValue.check_uniqueness("username", self.request.get('username'))) that raises TypeError: get() got an unexpected keyword argument 'username' what should I do? tnx -
No module named 'django' in conda virtualenv
I hadnt any python installed globally,just miniconda. Then created a virtualenv(conda) and installed django there. Now when I do "django-admin.py startproject projectname" (anaconda prompt,under created virtualenv) first it asked how to open that file & I set it to default python of miniconda ("C:\Users\1\Miniconda3\python.exe").Then it shows: Traceback (most recent call last): File "C:\Users\1\Miniconda3\envs\Work_manager\Scripts\django-admin.py", line 2, in <module> from django.core import management ModuleNotFoundError: No module named 'django' sys.path of that virtualenv: ['', 'C:\\Users\\1\\Miniconda3\\envs\\Work_manager\\python36.zip', 'C:\\Users\\1\\Miniconda3\\envs\\Work_manager\\DLLs', 'C:\\Users\\1\\Miniconda3\\envs\\Work_manager\\lib', 'C:\\Users\\1\\Miniconda3\\envs\\Work_manager', 'C:\\Users\\1\\Miniconda3\\envs\\Work_manager\\lib\\site-packages'] django-admin.py is located at "C:\Users\1\Miniconda3\envs\Work_manager\Scripts" & its shebang is "#!C:/Users/1/Miniconda3/envs/Work_manager\python.exe".
