Django: Slow query set to retrieve the order in which the specified tags are mostly included
I would like to get the so-called similar posts, but for some reason the following query set is For some reason, the following query set takes a long time.

django API view for javascript Ajax request
Let's say I have a Chart demo class Chart(models.Model): data = models.TextField() I store and load data in format of JSON, manipulate data and tries to render a chart on frontend. User case can be: user use app interface to generate data, upload it data is uploaded to backend and stored within an Chart instance use detail view and a redirect url to illustrate the result def chartDetailView(request, pk): chart = Chart.objects.get(pk=pk) return render(request, 'chart/chart.html', {'data': chart.data}) there are many website that allows costume JS request, for example, Web: how to redirect to a CodePen or JsFiddle with information filled?. since the static page only requires a data context to perform functionality, is there a way I can build an Ajax for javascript to open a new tab for the view? I mean, to code a view which can be requested by anchor link, form, Ajax or fetch with data passed in by JS, and return a static page. (no Chart instance stored) sorry the question may seems ignorant to you, I have learned little about rest framework. I will be very grateful for any suggestion you make. any source to look at. -
How to default language - error in changing it - Django
I have been struggling for quite a while with translation in django. I want to set a default language that is being set everytime user access the website (in a new session). I have studied django documentation, and I found the following algorithm: First, it looks for the language prefix in the requested URL. This is only performed when you are using the i18n_patterns function in your root URLconf. See Internationalization: in URL patterns for more information about the language prefix and how to internationalize URL patterns. Failing that, it looks for a cookie. The name of the cookie used is set by the LANGUAGE_COOKIE_NAME setting. (The default name is django_language.) Failing that, it looks at the Accept-Language HTTP header. This header is sent by your browser and tells the server which language(s) you prefer, in order by priority. Django tries each language in the header until it finds one with available translations. Failing that, it uses the global LANGUAGE_CODE setting. So I am trying to set the language prefix in the requested URL. I have configured my app as follows: settings.py MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'django.contrib.messages.middleware.MessageMiddleware', 'django.middleware.clickjacking.XFrameOptionsMiddleware', 'crm.middleware.RequestMiddleware', ] ....

Button type "submit" doesn't let bootstrap modal to open but type="button" doesn't fulfill my need
I have a web page in which there is an input field. And below is an edit button. When I enter some text in the input field and press the edit button, a modal pops up and there is an input field in it also. I want to pass the text from the first input field to the input field in the modal window. But then a problem arises. The modal window only opens when the edit button has type="button". But this type="button" doesn't submit the text input to the backend when I click the edit button. It submits the text to the backend when I use button type="submit", but then the modal doesn't open because the page reloads.

Django - Create random dummy data for testing that doesn't break the test suite
I'm trying to think of a way to create random test data of a certain model type for running python manage.py test. So for example if I have a model Post like below. model.py class Post(models.Model): uuid = models.UUIDField(primary_key=True) created = models.DateTimeField('Created at', auto_now_add=True) updated_at = models.DateTimeField('Last updated at', auto_now=True, blank=True, null=True) creator = models.ForeignKey( User, on_delete=models.CASCADE, related_name="post_creator") body = models.CharField(max_length=POST_MAX_LEN, validators=[MinLengthValidator(POST_MIN_LEN)]) some sort of library that'll generate this with random body, random creator from user table would be nice. I tried factory boy, but when the test DB rolls back the DB after a test function it seems to rollback factory boy created dummy data as well even if it's declared in setUpTestData function. This rollback process causes a constrain error since the original data no longer exists. What's a good library or way to create dummy data for Django testing that doesn't break the test suite? dummy_factory.py class PostFactory(DjangoModelFactory): class Meta: model = Post creator = factory.Iterator(User.objects.all()) body = factory.Faker('text') Note: Another option is to just create a function let's say make_dummy_post that uses Post.objects.create() and randomly samples a User and users factory boy to generate body, but I feel like there's a better way to do it … -

Pytest-xdist does not honour settings.DATABASES (or I am doing something wrong)
I am trying to use pytest-xdist for running parallel tests. It works and I see improved performance. To improve further more, I wanted to provide it multiple databases by using django_db_modify_db_settings_xdist_suffix I override that functions in my conftest.py. Since I have four workers, I created four databases manually. Then I use conftest to modify the settings.DATABASES to test for DBNAME against DBNAME_ I verified that my settings.DATABASES has changed and is correct. But the queries are still going to old db DBNAME (which is no longer in my settings.DATABASES) What could be going wrong? Do I need to make any other change? Or change in conftest.py fixture is enough? Thanks in advance for any help or direction. -
DJANGO PARENT AND CHILD CLASS DEFINITION
I actually defined a child class that would inherit the same attributes from the parent class. I also registered the models because I needed to work with them through the admin site just to ensure they work as intended. On accessing the child class at the Django's admin site, the error message displayed; Exception Type: TypeError Exception Value: init() missing 3 required positional arguments: 'content', 'topic', and 'date_added' This was my syntax: class Topic_SON(Topic_SHIM): """A class that models research topics related to Nursing Sciences (NS).""" def __init__(self, topics, date_added): """Initializes attributes from the parent class""" super().__init__(topics, date_added) class Content_SON(Content_SHIM): """A class that models research topic contents related to NS.""" def __init__(self, content, topic, date_added): """Initializes attributes from the parent class""" super().__init__(content, topic, date_added) I feel my approach to defining the child class isn't good enough.

python selenium chromedriver high CPU usage on parallel execution

I'd like to know how can I significantly decrease high CPU usage because even if I run 5 scans at a time the CPU usage still hits more than 50%?

Django Admin page outdated? showing nonexistent model
My django admin page is still showing a model I used to have. I have deleted this model in the code, Then I updated the imports / serializers and registered the new model I made to admin: admin.site.register(watcher_item_tracker_db) and then ran python .\manage.py makemigrations python .\manage.py migrate I have also tried: python manage.py migrate --run-syncdb However, when I go to the admin page for django I can still see the old model I used to have, and I cannot see the new model. Whenever I click on the old model that should not be there, I get this error: OperationalError at /admin/jobs/selenium_watcher_item_db/ no such table: jobs_selenium_watcher_item_db Request Method: GET Request URL: http://10.0.0.233:8000/admin/jobs/selenium_watcher_item_db/ Django Version: 3.1.1 Exception Type: OperationalError Exception Value: no such table: jobs_selenium_watcher_item_db There is no mention of "selenium_watcher_item_db" in my code anywhere after I replaced it with the new item, I tried everything I could think of other than restarting. -
