Django Form - Override standard validation message from within custom validator function

DRF APIClient Delete data arrives in request.data, not request.query_params
I use DRF's APIClient to write automated tests. And while is was writing the first delete test, I found it very strange that the data passed through arrived in request.data, while if I use Axios or Postman, it always arrives in request.query_params. Any explanation as to why this is, and preferably a method to use APIClient.Delete while the data arrives in query_params would be great! My test: import pytest from rest_framework.test import APIClient @pytest.fixture() def client(): client = APIClient() client.force_authenticate() yield client class TestDelete: def test_delete(client): response = client.delete('/comment', data={'team': 0, 'id': 54}) And my views from rest_framework.views import APIView class Comments(APIView): def delete(self, request): print(request.query_params, request.data) >>> <QueryDict: {}> <QueryDict: {'team': ['0'], 'id': ['54']}> Looked into DRF's APIClient. Feeding towards params doesn't seem to help. The delete method doesn't seem to have direct arguments that could help as well. So I'm a bit stuck. -
I am not getting expected result when I am multiplying price with quantity
I am working on a billing application. When I need to generate a bill, I open the CREATE form and I enter the quantity and price of two items. The quantity, price and total of both the items are stored in the django. suppose i want to change the quantity in Bill then i have made a similar form i call edit form. So when I edit the quantity and price of both the items in the edit form, then the first item's multiplication is getting correct but the second item's multiplication is getting wrong.

Strange behaviour when rendering X-Axis ticks
I'm rendering a chart with matplotlib through panda's df.plot() method, but somehow the tick labels on the X-Axis seem to be messed up. There seems to be a layer of numeric text above my "real" tick labels. I have no idea where this comes from. Strangely enough, this only happens in our production and staging environment, not in dev. Maybe it also has to do with gunicorn or django's dev server. Has somebody made this experience before? Here's the plot result: and this is the output when I clear the ticks with .set_xticks([], []): Here's a portion of my code, there's some abstraction but I think it should be understandable. self.data is a pandas dataframe. It outputs base64-encoded png data: class Line(ChartElement): def draw(self): self._plot = self.data.plot(kind='line', color=self.colors) self._rotation = 'vertical' self._horizontalalignment='center' # self._plot.set_xticks([], []) # ... class ChartElement(): # ... def base64(self): self.draw() figfile = BytesIO() if not self._plot: raise ValueError("Plot not generated.") if self._legend: self._plot.legend(self._legend, **self._legend_args) #plt.legend(self._legend, loc='upper center', bbox_to_anchor=(0.4, .05), ncol=5, fancybox=False, prop={'size': 6}) plt.setp(self._plot.get_xticklabels(), rotation=self._rotation, horizontalalignment=self._horizontalalignment, fontsize=8) self._plot.set_ylabel(self.y_title) self._plot.set_xlabel(self.x_title) #plt.figure() fig = self._plot.get_figure() fig.autofmt_xdate() if self.size and isinstance(self.size, list): fig.set_size_inches(inch(self.size[0]), inch(self.size[1])) fig.savefig(figfile, format='png', bbox_inches='tight') figfile.seek(0) figdata_png = base64.b64encode(figfile.getvalue()) plt.clf() plt.cla() plt.close('all') plt.close() return figdata_png.decode('utf8') -

I'm trying to find a way to make them go to different pages/views according to their different domains. I went through https://docs.djangoproject.com/en/4.0/ref/contrib/sites/ Sites documentation and am still stuck. The view that I'm trying to make work is this: def my_view(request): # current_site = request.get_host current_site = Site.objects.get_current() if current_site.domain == 'example2.com': html = "<html><body>Hello World at Example2 two</body></html> " + "current_site.domain=" + current_site.domain Site.objects.clear_cache() return HttpResponse(html) pass elif current_site.domain == 'example.com': html = "<html><body>Hello World at Example1 one</body></html> " + "current_site.domain=" + current_site.domain Site.objects.clear_cache() return HttpResponse(html) pass else: html = "<html><body>Hello World</body></html> " + "current_site.domain=" + current_site.domain Site.objects.clear_cache() return HttpResponse(html) pass I also tried changing the domain like below(It was done within a python shell within a pipenv shell), however it doesn't change it automatically by the domain address and will set it permanently to whichever one I saved: ((django-todo-react) ) ➜ backend git:(master) ✗ ./manage.py shell Python 3.7.0 (v3.7.0:1bf9cc5093, Jun 26 2018, 23:26:24) [Clang 6.0 (clang-600.0.57)] on darwin Type "help", "copyright", … -
What are the risk for Secret KEy in Django?
I have a question regarding Django and Secret Key. Unfortunately, I've did a commit to a public repositary with secret key visible. Then I got a message: GitGuardian has detected the following Django Secret Key exposed within your GitHub account. I then immediatelly deleted this repo from my github but still worried if something can happen to me. The app was just hello world on my localserver. I red some articles that it is very dangerous but I am not sure if someone can hack me by this. Can you advise? Thanks. -
