Unable to run Selenium tests for a Django app using Selenium docker services in GitLab-CI
Whenever I run my Selenium tests in GitLab-CI, I get a WebDriverException from Selenium. I've tried two different set ups, both of which run fine locally using Docker, but neither of which work in CI. Using Selenium Grid in CI, when I try to set up the remote driver I get the message Error forwarding the new session Empty pool of VM for setup Capabilities {acceptInsecureCerts: true, browserName: firefox, marionette: true, moz:firefoxOptions: {args: [-headless]}} Using standalone Firefox, I seem to be able to set up the remote driver, but when I run the tests I get Reached error page: about:neterror?e=dnsNotFound&u=http%3A//runner-dzqg9xmx-project-57-concurrent-0%3A38153/news/&c=UTF-8&f=regular&d=We%20can%E2%80%99t%20connect%20to%20the%20server%20at%20runner-dzqg9xmx-project-57-concurrent-0. If anyone can point me at a working GitLab-CI configuration that uses Selenium docker images as services, or tell me what's wrong with my configurations below, I'd be grateful. Using Selenium Grid Selenium Grid would be my preferred method because it would make it easier for us to run tests in multiple browsers. base/tests/utils.py I set up my tests using this base class. class SeleniumTestCase(LiveServerTestCase): host = os.environ('HOSTNAME') @classmethod def setUpClass(cls): super().setUpClass() options = webdriver.FirefoxOptions() options.headless = True cls.browser = webdriver.Remote( 'http://selenium-hub:4444/wd/hub', webdriver.DesiredCapabilities.FIREFOX, options=options, ) .gitlab-ci.yml test: stage: test image: $CMS_IMAGE_NAME variables: HUB_HOST: selenium-hub HUB_PORT: 4444 START_XVFB: 'false' services: - … -

Filtering for entities that have equal related entities
I'd like to build a queryset that finds balls with equal attributes. 2 models exist: Ball | id | name | +----+----------+ | 1 | Neptun | | 2 | Speedy | | 3 | Highway | BallAttribute | id | ball_id | key | value | +----+--------------------+-------+ | 1 | 1 | color | blue | ← | 2 | 1 | size | xxl | ← | 3 | 2 | color | blue | | 4 | 2 | size | xl | | 5 | 3 | color | blue | ← | 6 | 3 | size | xxl | ← The equal attributes are marked with a ←. So in the end, I'd like to get the balls Neptun and Highway in return (Speedy is not selected because size is different, and all attributes are required to be equal). Please keep in mind that the required attribute keys and values are not known, so solutions like these are not possible: Ball.objects.filter( balls__key="color", balls__value="blue" ).filter( balls__key="size", balls__value="xxl" ) How can I build such a queryset with Django? -
Why HTTP response returns 2 codes
This is a django project, a very simple one indeed, i got a question about the response code of the HTTP header. I am running it on localhost. # URL Patterns in the Project folder. urlpatterns = [ path('blog/', include(blog.urls)), ] # URL Patterns in the blog folder. urlpatterns = [ path('index/', blog.views.index, name='blog_index'), path('about/', blog.views.about, name='blog_about') ] Everything runs fine but the shell response is: [21/Aug/2019 21:15:54] "GET /blog/index/ HTTP/1.1" 200 144 The question is about the HTTP Header response 200 144 After playing with urllib a bit i used to think that headers send only 1 response code 200 OK For some reason django sends 2 codes 200 OK 144 Corresponds with HTTP 404. # Reference https://developer.twitter.com/en/docs/basics/response-codes.html -

How to troubleshoot Django web app connection to Teradata?
Can anyone please help me to troubleshoot this? A new Unix server is setup as test environment for an existing production django web app/server. On the test server I can pull data using bteq, but the web app doesn't (i.e. the json data doesn't populate. Everything else looks fine). All the configuration/settings are the same as the production server. I tried below steps in the production server and it returned with data, but in the test server I got the error. python manage.py shell >>> from project_web.shared_functions import teradata_con >>> import json >>> import pandas as pd >>> sql = """select distinct rgn_num, rgn_nm from RLDMPROD.SITE_HIER;""" >>> pd.read_sql(sql, teradata_con()) Error: python: libltdl/ltdl.c:1197: try_dlopen: Assertion `filename && *filename' failed.

Custom 404 and 500 pages in django with -> DEBUG = True
I want to present the sample of my website to a client and it isn't quite finished yet but it is very important for me to hide the errors and to not show my codebase which django does if a server error occurs in development mode. Like so - Django depicting what went wrong Also I cannot turn DEBUG = False as in that case the media files aren't displayed as they are currently being served locally. Which won't be served if DEBUG = False. So is there a way to serve media files locally with DEBUG = False or to display custom 404 and 500 pages with DEBUG = True. -

Why does Django run server hang when using docker-compose up?
When I run docker-compose up, Django starts to load. It goes thru the about four steps. After it does a system check and identifies (0 issues), it stops at displaying the current date and time.

creating navigation based on models with foreign keys
I'm having trouble finding a solution, or even where to look for a solution to this, and am a beginner with Django. I'd like to create a dynamic navigation for a project I'm working on. from django.db import models from tinymce import models as tinymce_models class League(models.Model): name = models.CharField(max_length=50) description = tinymce_models.HTMLField() crest = models.ImageField(upload_to='league-crests/', default=0) def __str__(self): return self.name class Club(models.Model): name = models.CharField(max_length=50) description = tinymce_models.HTMLField() crest = models.ImageField(upload_to='club-crests/', default=0) league = models.ForeignKey(League, on_delete=models.CASCADE, default=0) def __str__(self): return self.name Basically I'd like a top level nav called "Leagues" with a dropdown list of all leagues saved in the database. For each league i'd like a second level dropdown with the clubs in each league. I've been googling around but haven't found anything pointing me in the right direction. -

Django routing - The empty path didn't match any of these
Very basic question and I was surprised I wasn't able to find an answer. I'm just starting looking at django and did an out-of-box intallation. Created a project and created an app. The default content of urls.py is very simple: urlpatterns = [ path('admin/', admin.site.urls), ] And if I open the django site home page, I get the content with a rocket picture. However, like I said, I have created another app in the project, let's say called 'bboard'. And I have created a simple 'hello world' function in bboard/views.py def index(request): return HttpResponse('Hello world') to enable it for access through browser, I have modified the original urls.py file in the following way: from bboard.views import index urlpatterns = [ path('admin/', admin.site.urls), path('bboard/', index), ] This way I can access localhost:port/admin and localhost:port/bboard URLs, but if I try to open the home page with localhost:port now, I get Page not found error. Using the URLconf defined in samplesite.urls, Django tried these URL patterns, in this order: admin/ bboard/ The empty path didn't match any of these. if I comment out the second item in urlpatterns list, everything works. So why does the additional pattern impact this and what needs to … -

Django tutorial part 3 - bad link or directory structure
I'm doing the tutorial at: https://docs.djangoproject.com/en/2.2/intro/tutorial03/ It says to make a templates directory under the polls application (which is under 'mysite'), such that I have a tree that looks like this: mysite settings.py urls.py wsgi.py polls migrations templates polls index.html views.py models.py admin.py apps.py tests.py urls.py manage.py In the template they want me to write: {% if latest_question_list %} <ul> {% for question in latest_question_list %} <li><a href="polls/{{ question.id }}/">{{ question.question_text }}</a></li> {% endfor %} </ul> {% else %} <p>No polls are available</p> {% endif %} The page loads, but if I click the link it wants to take me to 'localhost:8000/polls/polls/1' and that does not exist. There are one too many '/polls' Question is, was the template directory supposed to go one level higher, under mysite? or should be not have '/polls' in the hyperlink? Despite their little explanation, I do not understand why we'd want to have 'polls/templates/polls'. It seems to me that we can tell it is polls if it is under polls already. -

Django Tempus Dominus TimePicker Format
When I submit a form after picking a time using the django-tempus-dominus TimePicker widget, I receive no error, but the form is not saved to the database, and does not show up in the admin page. I receive a visual browser indication that something is incorrect with my TimeFields. I can successfully create a new form from the admin page, and only see the issue when submitting from my form page. I'm not sure whether this is an issue with the 'format' of the TimePicker widget in my forms.py, an issue with my TIME_INPUT_FORMATS in my settings.py, or something else. If I use a DateTimeField with a DateTimePicker widget for start_time and end_time, and change the 'format' in my widget to 'YYYY/MM/DD hh:mm: A', instead of using a TimeField with a TimePicker widget, the form works correctly, and when submitted, can be viewed from the admin page.
