How to automate mutations in graphene with apscheduler
I am setting up a schedule template to create an event to notify users to do a stock count periodically. I could do this by calling an instance of the model inside the scheduler but my mutation auto-creates an event that is linked to the schedule. Here's my mutation class: class CreateStockCountTemplate(graphene.Mutation): stock_template = graphene.Field(StockCountTemplateType) success = graphene.String() class Arguments: product_ids = graphene.List(graphene.Int, required=True) event_type = graphene.Int(required=True) assigned_user_ids = graphene.List(graphene.String, required=True) designated_user_ids = graphene.List(graphene.String, required=False) outlet_id = graphene.Int(required=True) scheduled_time = graphene.String(required=True) frequency = graphene.Int(required=False) @login_required @user_permission('Manager', 'Admin') def mutate(self, info, **kwargs): template_instance = StockCountTemplate() template_fields = stock_counts.get_template_fields(**kwargs) schedule = kwargs.get('scheduled_time') with SaveContextManager(template_instance)as stock_tempalate: scheduled_time = make_aware(parser.parse(schedule)) event_type = setattr( stock_tempalate, 'event_type', kwargs['event_type']) description = 'Stock count on auto scheduling' event = Event( start_date=scheduled_time.date(), end_date=scheduled_time.date() + timedelta(days=7), start_time=scheduled_time.time(), end_time=scheduled_time.time(), event_title=f'Stock count', description=f'{description}', event_type=event_type) stock_tempalate = stock_counts.add_fields_to_template( template_instance, **template_fields ) event.save() stock_tempalate.event = event stock_tempalate.save() to_email = stock_tempalate.assigned_users.values_list( 'email', flat=True) email_stock_template = 'email_alerts/stocks/stock_email.html' subject = 'Stock counts alert' context = { 'scheduled_time': datetime.strftime( stock_tempalate.scheduled_time, "%d-%b-%Y"), 'by': str(info.context.user.email), 'template_type': 'Stock counts', 'small_text_detail': 'Hello, you have been assigned to carry' ' out stock counts' } send_mail = SendMail(email_stock_template, context, subject, to_email) send_mail.send() message = SUCCESS_RESPONSES[ "creation_success"].format("Stock count template") return CreateStockCountTemplate( stock_template=stock_tempalate, success=message) And in … -

How to setup docker-compose, pytest, Selenium Driver and geckodriver/chromedriver correctly
I am testing my django app with pytest. Now I want to use Selenium for system tests. I am also using docker so to execute my tests I do docker-compose -f local.yml run django pytest When I try to use Selenium I get the message that 'geckodriver' executable needs to be in PATH.. I read many questions here on SO and I followed the instructions. Yet, I think my path can't be found because I am executing everything in a docker-container. Or am I mistaken? I added the geckodriver path to my bash-profile by checking my path with: which geckodriver. The result of this is:/usr/local/bin/geckodriver Then I added this to my profile and when I type echo $PATH I can see this: /usr/local/bin/geckodriver/bin:. So I assume all is set correctly. I also tried setting it manually doing: self.selenium = webdriver.Firefox(executable_path=r'/usr/local/bin/geckodriver') Since I still get the error I assume it has sth to do with docker. That's why my specific question is: How can I setup the PATH for geckodriver with pytes, selenium and docker-compose? Any help or hint into the right direction is very much appreciated! Thanks in advance! Here is my docker-compose file as requested: FROM python:3.6-alpine ENV PYTHONUNBUFFERED … -

Why can't I get the API data using django again?
Alright, I have a web app I'm developing locally, part of the app uses cryptocompare, well contrary to my previous experience on using API in Django(because previously i've been able to get data from cryptocomapare through there API) I couldn't even print the data to the console not to talk of template, I have even checked different other means of doing this in python on youtube and blogs but I don't seem to miss anything too(at least as far as I'm concern, but technically speaking something is wrong). I have done the following creating the app in Django; I have the app in the settings/installed-app I have my api key linked accordingly(at least as far as I can understand) The crypto code is like so for the Django import requests def cryptos(request): api_rqt = requests.get( 'https://min-api.cryptocompare.com/data/v2/news/?lang=EN&api_key={my-app-key) api = json.loads(api_rqt.content) print(api_rqt) context = {'api': api} template = 'home.html' return render(request, template, context) <div> {% for api in api.Data%} <h4><a href="">{{api.title}}</a></h4> <h5>By <a href=""></a> <label>|</label> <i>{{api.published_on}}</i></h5> <p>{{api.body}}</p> <a href="{{api.url}}" target="_blank" class="btn btn-secondary"> Read More ...</a> {% endfor %} </div> I expect the output to show me news summary from cryptocompare but nothing is shown. And my Django server is running very well. -

Generate form classes in Django

Handling related models in DRF and getting the right swagger docs for it

What is the value of self._db by default in Django?
