coveralls doesn't recognize token when dockerized django app is run in TravisCI, but only from pull requests
I'm getting this error from TravisCI when it tries to run a Pull Request coveralls.exception.CoverallsException: Not on TravisCI. You have to provide either repo_token in .coveralls.yml or set the COVERALLS_REPO_TOKEN env var.

How to get two distinct objects from the same view function in django according to the requirements?
I have 3 models in Django which are like: class Category(models.Model): name = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) class Subcategory(models.Model): name = models.CharField(max_length=100) slug = models.SlugField(max_length=100, unique=True) class Product(models.Model): name = models.CharField(max_length=200, unique=True) category = models.ForeignKey(Subcategory, on_delete=models.CASCADE, related_name='products') slug = models.SlugField(max_length=150, unique=True) The view function which I want to modify currently looks like this: def product_list(request, category_name): subcategory = get_object_or_404(Subcategory, slug=category_name) subcategory_name = subcategory.name product_list = subcategory.products.all() context = { 'name':subcategory_name, 'product_list':product_list, } return render(request, 'products/product_list.html', context) In one of my html templates each category is displayed along with the subcategories under it. If anyone clicks on the category name instead of the subcategory under that category name, I want the views function to display all the products which come under that category and not just one subcategory under that given category. I can create a separate view to do that but I want to know if there's a way to do that in the same view function. -

How exactly does CASCADE work with ManyToMany Fields in Django
Im Wondering how exactly does CASCADE work with ManyToMany Fields in Django. A short example: class Project(Model): name = TextField(null=False) class Job(Model): projects = ManyToManyField(Project, on_delete=CASCADE, null=False) name = TextField(null=False) As you can see I have a ManyToManyField here. So basically a Project can have mutiple Jobs and a Job can belong to Multiple different Projects. What I want is that a Job is automatically deleted only when all Projects it belongs to are deleted. Does CASCADE work like that in this scenario? -

Visualize link has been clicked or not
I'm currently working on a web app in which I would like to display to the user whether they have visited the link already or not. The code that displays the links is fairly simple, as seen below. <ul> <li><a href="http://google.com">google</a></li> <li><a href="http://facebook.com">facebook</a></li> <li><a href="http://amazon.com">amazon</a></li> </ul> What I would like is to visualize that a link has been clicked by just adding a checkmark, or something along those lines, to the right of the link. How would I go about doing that? I'm working with Django for this project so a Django-specific solution would be great. -
npx create-react-app command does not work, returns ES module error instead
Here is the command that I ran to try to create a React app and the resulting error log. I have been able to successfully run it three times before with the command $ npx create-react-app, but now every time that I run it, it does not work and instead returns an error related to ES modules. I have been experimenting with many ways to integrate React with Django, but I don't think that I edited any core files in doing so that would have caused this error. I am completely new to React and Node.js so any advice would be greatly appreciated. npx: installed 99 in 7.591s Must use import to load ES Module: /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/is-promise/index.js require() of ES modules is not supported. require() of /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/is-promise/index.js from /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/run-async/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules.

Efficient way of avoiding adding duplicate entries to Django model
I've read quite a few posts on how to make a Database/Model unique in Django and it all seems to work. However, I do not see any posts discussing an efficient way of avoiding adding duplicate entries to a database. My model looks like this: # from app.models class TestModel(models.Model): text = models.TextField(unique=True, null=True) fixed_field = models.TextField() The way I currently avoid adding duplicate entries without getting an error is as follows. # from app.views posts = ["one", "two", "three"] fixed_field = "test" for post in posts: try: TestModel(text=post, fixed_field = fixed_field).save() except IntegrityError: pass If I would not do this I would get an IntegrityError.

I would like to generate django.po files but when I'm trying to use this command: docker-compose run web python3 manage.py makemessages -l en I got this error: CommandError: Can't find msguniq. Make sure you have GNU gettext tools 0.15 or newer installed. Meanwhile, when I directly access to my container, it works: (Here, ad2b13f2fe87 is the ID of my django-container) docker exec -it ad2b13f2fe87 bash root@ad2b13f2fe87:/code# gettext --version gettext (GNU gettext-runtime) 0.19.8.1 ... root@ad2b13f2fe87:/src# python3 manage.py makemessages -l en processing locale en Can someone explain me what the issue is? Thank you. -
