Python Django - Passing in multiple parameters to Factory during testing
I'm currently working on a practice social media app. In this app, current users can invite their friends by email to join the app (specifically, joining a 'channel' of the app, like Discord). For this project, I'm working on functionality where a user will get an error if they try to invite someone who is already in the app (meaning people who are already in the app's database). I'm working on unit tests that ensures the error messages pop up when users are detected as already existing. I managed to get my first scenario working, but I'm a bit stumped for the second one. Here is a file that is central to both tests. factories.py class ChannelFactory(factory.django.DjangoModelFactory) class Meta: model = Channel id = int name = str class CurrentUserFactory(factory.django.DjangoModelFactory) class Meta: model = CurrentUser user_email = user_email channel = models.ForeignKey(Channel) Scenario #1 (currently working) - one new user is invited to join the app but already exists in the app's database test_forms.py from tests.factories import ChannelFactory, CurrentUserFactory @pytest.mark.django_db def test_that_current_user_cannot_be_reinvited(email, error_message): """user that is already in the specific channel cannot be reinvited""" email = "user@test.com" error_message = "user@test.com already exists in this channel" # I am not specifying the … -

What does django's Manager.create() method do?
I was poking around in the rest_framework trying to figure out how it works, and came across a call to Model.objects.create(), but I can't for the life of me find the create() method for django model managers in the docs or the source code. It looks to be dynamically generated. What does it do, exactly? Where can I find its code? If I wanted to override it, what would my implementation have to do? I found this question but it only says to call the super().create() method. -
Django crispy form is not posting or view is incorrect
I am currently working on a note/comment system. It is intended to work as adding notes to each individual projects. For example, you set up a "Project" and there is a note or comment sections intended for adding updates to the project. Here is my view.py for updating the project.

Django to Droplet: Failed to load resource: the server responded with a status of 500 (Internal Server Error)
I am getting Internal Server Error while setting up GNINX... On both the domain and on the droplet IP: Failed to load resource: the server responded with a status of 500 (Internal Server Error) Correct response was give by: curl --unix-socket /run/gunicorn.sock localhost also sudo systemctl status gunicorn works as expected Gunicorn bind als worked on both the droplet IP and the domain. There is just something going on with GNINX. So I gues it has something to do with the file settings. Tried to reinstall the Droplet multiple times, Tried different settings and groups already, Nothing seems to work. -
How to implement sending a command from a page to Django via SSH?
How to implement sending a command from a page to Django via SSH? It is necessary that the page has a button that, when clicked, sends a command via SSH to the Ubuntu virtual machine. Good afternoon.

How to Run an ML model with Django and Celery

custom error handler django when using django-hosts
I have a system that has deployed django-hosts, all is working fine. Until now I have been handling 404 and 500 errors for production by utilizing the neat trick of just placing files 500.html and 404.html in the root of the templates folder. This very nicely handles these errors in production (debug=False). However, now I want to get a little more creative with my error handling messaging and feedback to the user. I have other projects where I have created a custom view for the error handling. e.g. def custom_error_500(request, exception=None): print ('error 500 ') #For debugging to verify view is being processed. return render(request, "errors/500.html", status=500) and then set this parameter at the bottom of the urls.py (appname is 'main') handler500 = 'main.errorviews.custom_error_500' This all works very nicely in a project that does NOT use django-hosts. The advantage of creating the custom view is that the context is past to the RequestContext to the template, whereas by default not the case (see reference). Now, I know with django-hosts here is magic going on in the way urls.py are processed for each host. Could this be the reason why?. I tried placing the hander500 setting in all the possible urls.py … -

How does Python "mysqlclient/MySQLdb" know where to find "libmysqlclient?"

Django passing context in JsonResponse
I am developing a webpage with filters to filter the results on the page. A Ajax is called, which sends the filters to my Django back-end. The results are filtered and the data should be passed back to the front-end. So now I need to pass my results of the models with context to the front-end. This leads to some problems. My Ajax: $(document).on('change', '#test-form', function (e) { e.preventDefault() var tags = []; $('input[name="tags[]"]:checked').each(function(i){ return tags[i] = $(this).val(); }); $.ajax({ type: 'POST', cache: false, url: "{% url 'core:jobSearch_nosearch' %}", data: { tags: tags, csrfmiddlewaretoken: $('input[name=csrfmiddlewaretoken]').val(), }, success: function(data) { console.log('yey') console.log(data) } }); }); Here my View: from django.core.serializers.json import DjangoJSONEncoder from django.utils.functional import Promise class LazyEncoder(DjangoJSONEncoder): def default(self, obj): if isinstance(obj, Promise): return str(obj) return super().default(obj) def jobSearch(request, **search): companies = Company.objects.all() if request.method == 'POST': ads = Ad.objects.all() search_job = request.GET.get('search') if search_job: ads = Ad.objects.filter(title__contains=search_job) tag_filter = request.POST.getlist('tags[]') for tag in tag_filter: print(tag) ads = ads.filter(tag__name=tag) print(ads) context = {'companies': companies, 'ads': ads} # context = {'companies': list(companies)} # context = {'msg': 'Success'} # return JsonResponse(serialize('json', ads, cls=LazyEncoder), safe=False) return JsonResponse(context) else: ads = Ad.objects.all() context = {'companies': companies, 'ads': ads} return render(request, 'core/jobSearch.html', context) As you … -

Heroku app successfully deploying, but receiving application error when loading site , please help to fix it
My logs don't indicate any errors as far as I can tell, but I'm receiving the following error when loading the site: An error occurred in the application and your page could not be served. If you are the application owner, check your logs for details. You can do this from the Heroku CLI with the command heroku logs --tail Below you can find the logs.

Impossible export django-parler translated fields with the common comand dumpdata
Is there any way to dump and load data with a TranslatableModel because with the common python manage.py dumpdata app.Organization -o fixtures/organizations.json Django command translated fields do not appear in the file. models.py: class Organization(TranslatableModel, Entity): translations = TranslatedFields( name = models.CharField(verbose_name=_("Name"), max_length=200), description = RichTextField(verbose_name=_("Description"), blank=True, null=True, config_name='default') ) status = models.CharField(verbose_name=_("Status"), max_length=50), organizations.json: [ { "model": "app.organization", "pk": 1, "fields": { "status": "Active" } }, { "model": "app.organization", "pk": 2, "fields": { "status": "Active", } } ] Any idea ? Thanks in advanced.
