Why is my project no longer updating when I write new code?
I have a react / django app. The django side hosts a sqlite database, and react displays its content as the front end. When I run the command python manage.py runserver it is hosted locally on port 8000. My specific problem is manifest when I make edits to my React code. Even after refreshing the page and restarting the server, my front-end still remains as it was before I had edited the code and saved. I have no errors, or warnings. The only way I seem to be able to make it work is by pushing to GitHub and then cloning the repository on my system again. Would anyone be able to help me understand my dilemma? (Please let me know if my question is not to par with the guidelines of Stack Overflow, this is my first time) -
Pass an argument back and forth between two templates in Django
I have an app that returns information from an API request to the user based on their search request. Lets call this template A. They can then click on a link at the bottom of the page which brings them to a "More games like this" page, template B, that uses the same API, but a different endpoint to display similar games. I want the user to be able to then click on any of the suggested game's titles and be brought back to template A, without having to do a search, and the page display the relevant information for the game that was clicked on. I have tried using url routing, such as {% url 'vgSearch' result.name %} in the href of the link to return the user back to template A. Then pass the result.name argument back through the original template A view. But I'm totally stumped on how to have it "catch" that information and display the API results. This is what I have: views.py def search(request, name=None): if request.method == 'POST': raw_result = request.POST.get('search') space_result = raw_result.replace(' ', '-') dot_result = space_result.replace('.', ' ') qmark_result = dot_result.replace('?', ' ') back_result = qmark_result.replace('/', ' ') colon_result = … -

Unable to serve static .gz file (MIME type ('application/octet-stream') is not executable)
I have a Django app, with a React frontend. I'm using compression-webpack-plugin to compress my js file. Here is my webpack configuration: const CompressionPlugin = require('compression-webpack-plugin'); module.exports = { entry: path.resolve(__dirname, "./assets/index.js"), output: { path: path.resolve(__dirname, "assets/bundles"), filename: "[name].js", publicPath: "/static/bundles/", }, plugins: [ new CompressionPlugin({ deleteOriginalAssets: true, }) ] }; This generates a file main.js.gz in my /static/bundles/ directory. In my Django settings, I've set the following: STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' When I go to /, the following HTML page is served: {% load static %} <!DOCTYPE html> <html> <body> <div id="app"> <!-- React --> </div> </body> <script src="{% static "/bundles/main.js.gz" %}"></script> </html> On my dev environment, I can see main.js.gz being loaded But on my prod environment, the content-type changes to application/octet-stream And in my console I get the error: Refused to execute script from 'https://my-website.com/static/bundles/main.js.gz' because its MIME type ('application/octet-stream') is not executable, and strict MIME type checking is enabled. I'm not sure what steps I can take here for the file to be recognized as a .gz or .js file -

So everything was working good the follow buttons were following a user, the following count on the profile was displaying the number of people a user follows, but there was one thing that was not working and it was the follower count. To add this I created a add_follower definition on a signals.py file but as soon as I did that The follow/unfollow button was not working due to a internal server 500 error, so after some investigation I realized that the 500 error was happening because there is this error DoesNotExist at /accounts/follow/username User matching query does not exist.

In Django, how do you update all objects when creating a new one with generic.CreateView?
I'm trying to create a model with an "order" field that automatically updates whenever a new object is created. (Later, I want to update it when you drag table rows around as well.) I started following this tutorial, but I'm stuck in trying to use the manager to actually create the object. This is my simplified code: # models.py class Entry(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=200) owner = models.ForeignKey( get_user_model(), on_delete=models.SET_NULL, null=True, blank=True ) order = models.IntegerField(default=1) objects = EntryManager() class EntryManager(models.Manager): def create(self, **kwargs): instance = self.model(**kwargs) with transaction.atomic(): results = self.filter( owner = instance.owner ).aggregate( Max('order') ) current_order = results['order__max'] if current_order is None: current_order = 0 value = current_order + 1 instance.order = value instance.save() return instance #views.py class EntryCreateView(LoginRequiredMixin,generic.CreateView): model = Entry fields = ['name'] def form_valid(self, form): form.instance.owner = self.request.user return super().form_valid(form) success_url = reverse_lazy('home') When I create a new Entry object here, I get something with an empty order field. Do I need to call the manager directly somehow? Thanks in advance! -

I'm trying to build a small BBS-like app in Django, and I want to be able to restrict users from deleting posts more than 30 minutes old. However, I can't get the datetime comparison to work in the template engine. Here is a snippet of my views: context = { ... "message_time" : datetime.utcnow() + relativedelta(minutes=-30) } And here is the django template in the html: {% if request.session.userid == post.user.id and post.created_at >= message_time %} <form action="/wall/message/{{ post.id }}/delete" method="POST"> {% csrf_token %} <button type="submit">Delete</button> </form> {% endif %} For some reason, the delete button doesn't appear with this snippet, however it works without it (i.e. the message id/session id functionality is fine). I've tried using different combos of relativedelta +/- 30 minutes, created_at greater/less than message_time, but nothing seems to work. -
Django: prevent readonly forms handling
Is there a way to prevent handling of readonly fields in a Django Form? I need to show the value to the user but if he inspect and change the value it is migrated to database on submit, how can I prevent that? This is the way I create the form (it's a formset actually): NotasFormSet = modelformset_factory(Nota, extra=0, form=FormularioCalificaciones) formset = NotasFormSet(queryset=Nota.objects.filter(materia=materia)) for form in formset: form.fields['trimestre1'].widget.attrs['readonly'] = not cierre_t1 form.fields['trimestre2'].widget.attrs['readonly'] = not cierre_t2 form.fields['trimestre3'].widget.attrs['readonly'] = not cierre_t3 form.fields['nota_final'].widget.attrs['readonly'] = not cierre_nf Template rendering: <form method="POST"> {% csrf_token %} {{ formset.management_form }} {% for form in formset %} {{ form.instance.alumno.user.get_full_name }} <br> {{ form }} <br><br> {% endfor %} <button type="submit">Calificar</button> </form> -
