'React is not defined' when installing component library that I'm trying to create using Rollup and React
I'm trying to create a React component library. I'm using Rollup for bundling the files. I'm generating build folder then running npm pack to get a .tgz file of the library. Then I'm installing that file in another project using file:filename.tgz and npm install. But when I run the server it shows me ReferenceError: React is not defined.

Django app with Azure AD account identity provider deployment to Azure Web app service fails
Background I am trying to deploy a Django web app with Azure AD as the account identity provider to Azure Web app services following the Microsoft tutorial. My app is registered on the Azure AD portal. It works well in development on localhost. Problem However, when i deploy it to Azure Web app services, it fails because it requests a redirect URI starting with http while Azure AD requires that any non localhost server must have a redirect URI starting with https. Specifically, it requests a redirect URI as http://myapp.com/auth/redirect. But, i am only allowed to register URI https://myapp.com/auth/redirect in Azure AD. This problem was addressed in a related Stackoverflow question The solution given was to "Run server with ./manage.py runserver_plus --cert /tmp/cert localhost:8000". This works great on localhost, but i am having trouble deploying it to Azure web app service. My deployment file stored in .github/workflows/deploy_on_<myapp>.yml has the deploy job defined as follows: deploy: runs-on: ubuntu-latest needs: build environment: name: 'Production' url: ${{ steps.deploy-to-webapp.outputs.webapp-url }} steps: - name: Download artifact from build job uses: actions/download-artifact@v2 with: name: python-app path: . - name: 'Deploy to Azure Web App' uses: azure/webapps-deploy@v2 id: deploy-to-webapp with: app-name: 'fno-calculator' slot-name: 'Production' publish-profile: ${{ secrets.AZUREAPPSERVICE_PUBLISHPROFILE_<secret> … -

How to use autocomplete-light with taggit?
What's suggested in the documentation doesn't work, so it can be assumed that no documentation exists. I tried what it suggests: models.py from django.db import models from taggit.managers import TaggableManager class SomeModel(models.Model): name = models.CharField(max_length=200) tags = TaggableManager() def __str__(self): return self.name views.py from dal import autocomplete from taggit.models import Tag class TagAutocomplete(autocomplete.Select2QuerySetView): def get_queryset(self): # Don't forget to filter out results depending on the visitor ! if not self.request.user.is_authenticated(): return Tag.objects.none() qs = Tag.objects.all() if self.q: qs = qs.filter(name__istartswith=self.q) return qs which doesn't work and results in an empty query set with an authenticated user. To be fixed, Tag.objects has to be changed to SomeWorkingModel.objects. Followed by registering endpoints: path( 'some-model-autocomplete/$', SomeModelAutocomplete.as_view(), name='some-model-autocomplete', ), which works fine when reversed or queried in browser. Then I place a TagField in the form: tags = TagField(label='', widget=TaggitSelect2('some-model-autocomplete')) and in the template, I include these at the end <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js"> </script> {{ form.media }} The result: a useless, large text area in the middle of the form that doesn't do or respond to anything. I don't care if a solution exists in assembly language as long as it works and it can be proven it works with this setup, suggestions for alternatives … -
