Is it possible to monitize a blog on heroku's hobby account?
Is it possible to monetize a blog on Heroku's hobby account? Is it ideal for such purposes? I have one on the free tier & I'm not sure about upgrading. Better yet, what hosting service is most suitable (affordability, efficiency) for a Django blog expecting web-traffic? -
Invoice template: render html table "Discount" column only if any item has a discount
Disclaimer, I haven't worked with Django or Python before, so any help/guidance is appreciated. I'm working on a quote/invoice template using Jinja/Django syntax. A quote has multiple line items, some of which may have a discount on them. I'd only like to render the "Discount" column in the html table if any one of the items has a discount on it. The trouble I am having is figuring out if any one item has a discount (either dollar or percent), and telling the template to render or not render that html conditionally as a result. This is a simplified array/list of line item data available: lineItems=[ {acv=64000.0 discount= discount_percentage= price=64000 quantity=1 name=Item One id=0} {acv=44000.0 discount=1500 discount_percentage= price=64000 quantity=1 name=Item One id=1} {acv=2000.0 discount= discount_percentage= price=64000 quantity=1 name=Item One id=2} ] At first I thought to create a global "hasItemDiscount" variable, and then use a for loop to iterate through the list items and update the global variable if any had a discount value than 0. Something to this effect: {% set hasItemDiscount = false %} {% for item in lineItems %} {% if item.discount > 0 or item.hs_discount_percentage > 0 %} {% set hasItemDiscount = true %} {% endif … -

How to paginate data from external api in Django?
I query external news api with Django. The api returns the total_results and by default 20 articles.Example response is in https://newsapi.org/docs/endpoints/top-headlines My Django view is def index(request): #default values us and general country = 'us' category = 'general' if request.method == "POST": try: country = request.POST['country'] category = request.POST['category'] except: #in case user does not choose country and/or category return HttpResponseRedirect(reverse("index")) news_request = requests.get(f"https://newsapi.org/v2/top-headlines?country={country}&category={category}&apiKey={env('API_KEY')}") news = json.loads(news_request.content) return render(request, "news/index.html", {"news":news}) Is there a way to paginate these kind of data? -
Install Django package via pip into another package (site-packages) instead of the main project
Let's say I have a project, ProjectA. In ProjectA, I installed the following package via PIP pip install wiki to embed a wiki system on my web page: https://pypi.org/project/wiki/ All wiki system files are stored in /Users/{my_username}/.virtualenvs/{my_virtualenv_name}/lib/python3.9/site-packages/wiki/ so when I want to do some modification, I have to do it in the path specified above (which I don't know if it is good practice). For now there has been no problem in modifying the templates, but the wiki will be used in an intranet, that means that I have to protect the files (especially the images) so that if a user wants to access an image, for example: http://projecta.com/img.png, the user has to be previously logged in to view that image. There are packages to protect media, like this one. The thing is, for that to take effect, I need to modify the models on my wiki (which are in a completely separate location from ProjectA) and replace ImageField with ProtectedImageField. My question is, how can I install (via pip) the django-protected-media package for wiki (previously installed via pip) instead of for ProjectA? Or, in other words, how can I install the package 'django-protected-media' and use it in 'wiki' instead … -

Django view with two forms not posting one
Im trying to use one form to get data for two different models, to do so, I changed my create view get_context_data function like this: class tarea_crear(CreateView): template_name = "crud_tareas/tarea_crear.html" form_class = tareaForm success_url = reverse_lazy('tareas:crear-tarea') def get_context_data(self, **kwargs): context = super(tarea_crear, self).get_context_data(**kwargs) context['form'] = {'audiosForm':audiosForm,'tareaForm':tareaForm} return context This allowed me to call both forms on my template, like this: (Dont worry, I remembered the crfs tag and the form) {{form.tareaForm.as_p}} {{form.audiosForm.as_p}} <input type="submit" value="Crear Tarea"> I also needed to validate some informationfrom the first form, and I did it like this in the view: def form_valid(self, form): titulo = form.cleaned_data['titulo'] if not any(i.isdigit() for i in titulo): return super(tarea_crear, self).form_valid(self, form) return super(tarea_crear, self).form_invalid(self, form) The problem is that when I do the POST of the form, only the first half of the data is actually sent, I know this because I cant call form.cleaned_data['audios'] in the view without getting an error. Any idea how to handle a View with two forms? -
Get previous and next Child objects in ordered Parent queryset (where Children can also be parents)
Say I'm trying to build a library of Books. A Book can have many Chapters. A Chapter can also have many Chapters. (For example, if you look at the Tables of Contents for Les Miserables, you'll see that Les Miserables is divided into volumes, the volumes are divided into books, and the books are divided into chapters. So for our purposes, "Les Miserables" is our Book model and its volumes, books, and chapters are our Chapter model.) What is the best way (or any way!) to generate the correct "previous" and "next" object for any given Chapter? I've decided to use Single Table Inheritance proxy models as outlined in this article: class Text(models.Model): type = models.CharField(max_length=255) title = models.CharField(max_length=255) body = models.TextField(blank=True, null=True) parent = models.ForeignKey( "self", related_name="children", default=None, blank=True, null=True, on_delete=models.CASCADE, ) order = models.IntegerField(blank=True, null=True) def __init__(self, *args, **kwargs): super(Text, self).__init__(*args, **kwargs) # If we don't have a subclass at all, then we need the type attribute to match # our current class. if not self.__class__.__subclasses__(): self.type = self.__class__.__name__.lower() else: subclass = [ x for x in self.__class__.__subclasses__() if x.__name__.lower() == self.type ] if subclass: self.__class__ = subclass[0] else: self.type = self.__class__.__name__.lower() class Meta: ordering = ["order", "pk"] … -
Page blocked by logged in user
My django site authenticates the user using firebase in the login page, which then redirects them to the "home/" (pick.html) after successful login.

Django Reverse Match when using AJAX

Sudden AWS ECS PermissionError for Django Collectstatic Command
I have an AWS ECS Task that runs a Django (Python) app and a Proxy for static files. Django has a command called collectstatic that copies all the static files into the shared folder that will be served by the proxy. I have been running this setup for a few months without any problems, but around 17 March 2021 I noticed that my deployment was not updating my website. Looking at my Django app logs I saw the error: PermissionError: [Errno 13] Permission denied: '/vol/web/static' I didn't make any configuration changes recently and after a week of experimentation, debug and frustration I noticed that a few other people from the same course that I followed to create this setup started having the exact same issue at the same time (basically a week ago). At this time my only guess would be that something must have changed within AWS itself, but I'm not sure what to look for. Any suggestions will be appreciated, thanks! -
Django - why am i not authenticated after logging in from Axios/AJAX?
I'm building a separated VueJS/Django app where Django will communicate with the Vue frontend using JSON. In order to be able to use the standard session authentication and django-allauth i will deploy the two apps on the same server and on the same port. Here is my problem: after i log in from the Vue app using Axios, i don't receive any response but i notice that a session is created on the db, so i'm assuming that i'm getting logged in. But if i try to reach and endpoint that prints request.user.is_authenticatedi get False, and request.user returns Anonymous, so i'm not logged in anymore. How can i solve this? Here is my Axios code: bodyFormData.append('login', 'root'); bodyFormData.append('password', 'test'); axios({ method: "post", url: "http://127.0.0.1:8000/accounts/login/", data: bodyFormData, withCredentials: true, headers: { "Content-Type": "application/json" }, }) .then(function (response) { //handle success console.log(response); }) .catch(function (response) { //handle error console.log(response); }); I think Django-Allauth supports AJAX authentication on its urls, but i don't understand how to make it return something and how can my Vue app stay authenticated once i submit the Axios form. Any advice is welcome! -

Django boolean annotate returning duplicates
I have the following models: class Institution(models.Model): pass class Headquarter(models.Model): institution = models.ForeignKey(Institution, related_name='headquarters') class Audit(models.Model): headquarter = models.ForeignKey(Headquarter, related_name='audits') And the following query (basically, if an institution has at least one audit then has_visits must be true: Institution.objects.annotate( has_visits=models.Case( models.When(headquarters__audits=None, then=False), default=True, output_field=models.BooleanField() ) ) The problem is that if an institution has 2 audits then the queryset returns duplicate rows. I imagine it has something to do with the joins at the SQL level but I'm not sure how to correct it. I found this answer but I don't think OuterRef is what I'm looking for in my situation. What's the right way to accomplish this?
