Trying to COPY adjacent folder into Docker image but copies the entire folder over
I have a directory structure like the following: project-root/ api/ docker/ Dockerfile ... src/ auth/ contact/ settings/ asgi.py settings.py urls.py wsgi.py manage.py client/ docker/ Dockerfile nginx.conf src/ App.js index.js In my API Dockerfile I'm trying to just copy src in to /app. However, I keep getting the entire api directory. What I expect to see is: app/ auth/ contact/ settings/ asgi.py settings.py urls.py wsgi.py manage.py This stage is the only one where src is copied over. The python-base and builder-base are either env vars or application dependencies. FROM python-base as production COPY --from=builder-base $VENV_PATH $VENV_PATH RUN chmod +x . /opt/pysetup/.venv/bin/activate COPY ../src /app WORKDIR /app CMD ["gunicorn", "-b", ":5000", "--log-level", "info", "config.wsgi:application", "-t", "150"] I've tried COPY ../src /app, COPY ./src /app, COPY src /app. How should I copy over just the src to app in this project structure? -
Need help iterating through each row in SQLite DB to render to html template
I'm using the Django framework with SQLite DB. I'm using SQL queries in my views.py and connecting that data to render on the frontend in my dashboard.html template. I'm having trouble iterating through each row in my database table 'scrapeddata'. When I view the dashboard, the data being rendered is all bunched up together in one div. I'm hoping to get each row in the database to render in one div each. I tried placing a for loop in my views.py but when I do that, I only get one row from the database rendered on dashboard.html. Any help is appreciated, thank you. views.py: def dashboard(request): connection = sqlite3.connect('db.sqlite3') cursor = connection.cursor() col1 = '''SELECT companyname FROM scrapeddata ORDER BY companyname ASC''' cursor.execute(col1) companyname = cursor.fetchall() col2 = '''SELECT name FROM scrapeddata''' cursor.execute(col2) name = cursor.fetchall() col3 = '''SELECT portfolio FROM scrapeddata''' cursor.execute(col3) portfolio = cursor.fetchall() people_data = [] data = { 'companyname': companyname, 'name': name, 'portfolio': portfolio } people_data.append(data) connection.close() if request.user.is_authenticated: return render(request, 'dashboard.html', {'people_data':people_data}) else : return redirect('/login') dashboard.html: Here's the for loop in the template. {% for data in people_data %} <div> <p>{{ data.companyname }}</p> <p>{{ data.name }}</p> <p>{{ data.portfolio }}</p> </div> {% endfor %} -
Django passing a variable through the path, causing path repetitions. how to get out of that loop?
I know this is an armature question but here goes. I have a url path as follows: path('projects/<s>', PL.projects), and i pass a string from the html template by putting it into an herf tag like so projects/some_string. this works once but then the base url changes to <ip>/projects/some_string. so when i try to excite the path to pass a string in that domain then I get an error as the url is now <ip>/projects/projects/some_string. how do i set it up so that i can pass as many strings as possible as many times as possible without having to clean my url in the browser everytime. Thanks for the help. -
Get cumulative running sum with group by in django orm
I have a table of two (relevant) columns. table: Transaction columns: transaction_date, amount I would like to get the cumulative amount for each month. So, for each month, get the sum of transactions from the beginning to that point in time. In PostgreSQL I would do something like this: SELECT date_trunc('month', transaction_date::date) AS formatted_transaction_date, SUM(SUM(amount)) OVER (ORDER BY date_trunc('month', transaction_date::date) ROWS UNBOUNDED PRECEDING) AS cumulative_transaction_amount FROM transaction GROUP BY date_trunc('month', transaction_date::date); I am trying to do the same in Django Orm. The closest I have gotten is this: Transaction.objects.values( formatted_transaction_date=TruncMonth('transaction_date') ).annotate( cumulative_transaction_amount=Window( expression=Sum('amount'), order_by=TruncMonth('transaction_date').asc(), frame=RowRange(start=None, end=0), ), ) This however throws an error: django.db.utils.ProgrammingError: column "transaction.amount" must appear in the GROUP BY clause or be used in an aggregate function I understand that the Django query I am executing is not identical to the PostgreSQL query. The PostgreSQL query runs SUM(SUM(amount)), while the Django query translates simply to SUM(amount). However, I was unable to find the syntax of Django to achieve same result. What am I doing wrong? -
One database with multiple django projects
I have two django projects connecting to same database. One of them is using authentication with custom user model and is working fine. Now i have to secure second project and use user authentication. It will be more or less similar to what we are using in first project. I tried creating models in second project but i think it is conflicting with already existing django tables. My question is how can we have two separate projects, each having their own django tables (auth and other). Till now i have tried and i am getting following error ValueError: The field admin.LogEntry.user was declared with a lazy reference to 'app.customuser', but app 'app' doesn't provide model 'customuser'. -

django coverage not covering the urls despite writing specific tests for the urls

Django - PermissionRequiredMixin - Return a 'permission_denied_message' in current View, instead of a 403 Page?
Django version 3.0.5 I want to use the PermissionRequiredMixin in my View to display a banner message the same way I would with the SuccessMessageMixin. For example, if a user attempts to delete an object and they do not have permissions, the permission_denied_message would essentially be treated as an error message an displayed in the current view as a banner message. Is that even possible? the code that I currently have does not work - it always redirects to the 403 page. see below: class DocDeleteView(PermissionRequiredMixin, SuccessMessageMixin, DeleteView): model = SlateDoc success_url = reverse_lazy('slatedoc-list') success_message = "SlateDoc was deleted!" permission_required = ('slatedoc.delete_slatedoc') raise_exception = True permission_denied_message = "Permission Denied" def delete(self, request, *args, **kwargs): if self.has_permission() is False: messages.error(self.request, self.permission_denied_message) else: self.object = self.get_object() self.object.soft_delete() messages.success(self.request, self.success_message) return HttpResponseRedirect(self.get_success_url()) -

redirect doesn't convert special characters correctly on redirect in django
I have a page in my django app that requires authentication. If the user hits mydomian/my_page the view will evaluate if the request is authenticated. If authenticated the request will get routed to the right html page (my_page.html). If the request is unauthenticated the request will be routed to the login page with a redirect: class MyView(View): def get(self, request): user = request.user context = { 'username': user.username } if user.is_authenticated and user.is_staff: return render(request, 'path/to/my_page.html', context) logout(request) return redirect('/admin/login?next=/my_page') This worked pretty well, when an unauthenticated user hit mydomain/my_page it will get routed to mydomain/admin/login/?next=/my_page and once authenticated it will get routed to mydomain/my_page with will serve path/to/my_page.html. Now I updated to the latest django version and the rerouting changed: When an unauthenticated request hits my page it gets rerouted to this url mydomain/admin/login/?next=/admin/login%3Fnext%3D/my_path. Once the login happens on that page, the page gets rerouted to mydomain/admin instead of mydomain/my_page. Then when I call mydomain/my_page it gets routed to the right page (since the request is authenticated). I tried replacing the redirect with return HttpResponseRedirect((('/admin/login?next=/my_page').encode('utf-8'))) but didn't work. I also couldn't find anything in the django docs on if and how the changed the redirect method. Any ideas? -

how to iterate multiple lists in django template

If you need more info I can give you.And also if you have another better way than this please let me know.

Django upload and read vcard object - loosing my mind
I am trying to let users of my Django app upload vcards through a form, parse those vcards on the fly and then serve some of the content back to the front-end without storing the vcards on server.
