Using custom fonts in TinyMCE API for editor in django admin
I am trying to use TinyMCE API in Django admin for blog post editing. It is working flawlessly. However, now I want to add custom fonts to my editor. As per tinymce documentation for adding custom fonts i have followed all steps but still cannot figure out what is wrong. Step-1: Add fonts as per menu option admin/base.html: font_formats:"Andale Mono=andale mono,times; ........ ; Montserrat = Montserrat , sans-serif",` Step-2: Import fonts in tinymce admin/base.html: {% extends "admin/base.html" %} {% load static %} {% block footer %} tinymce.init({ .... content_css: "{% static "TinyMCE/style.css" %}", content_style:"@importurl('https://fonts.googleapis.com/css2family=Montserrat:ital,wght@0,400;0,600;1,400&display=swap');", .... {% endblock %} TinyMCE/style.css @import url('https://fonts.googleapis.com/css2family=Montserrat:ital,wght@0,400;0,600;1,400&display=swap'); snapshot: the custom font is added in the dropdown menu 'Monstserrat' Step3: Import the font on the page admin/base.html {% block extrahead %} <style> @import url('https://fonts.googleapis.com/css2?family=Montserrat:ital,wght@0,400;0,600;1,400&display=swap'); * {font-family : 'Montserrat', sans-serif;} </style> {% endblock %} snapshot: the custom font changes in dropdown from fallback font to 'Monstserrat' Step4: Import the font on any published pages I am using tailwind in my project and my default font is Monstserrat which is perfectly working over the site style.css @import url('https://fonts.googleapis.com/css2?family=Montserrat:ital,wght@0,400;0,600;1,400&display=swap'); body{ font-family: Montserrat, sans-serif; } Problem: Although i see the custom font 'Montserrat' in the dropdown on tincymce editor but when … -
Reach django user from javascript template
I'm following Corey Shafer's django guide and I have run into some problems he doesn't cover. I'm trying to make profiles that are visible to everyone but only editable by the user itself. In my views.py I have a boolean "editable", and this part is working. However, I can't get that boolean to my js file... Code below. const button = document.getElementById("button"); button.addEventListener("click", () => { const form = document.getElementById("form"); var bool = {{ user.profile.editable }}; if(form.style.display == "none" && bool){ form.style.display = "block"; }else{ form.style.display = "none"; } }); When I inspect it in the browser it gives me a syntaxError because I'm using '{'. And here is the code from my views.py: @login_required def profile(request, username): user = User.objects.get(username=username) Profile.objects.get_or_create(user=request.user) editable = False if request.method == "POST": user_form = UserUpdateForm(request.POST, instance=request.user) profile_form = ProfileUpdateForm(request.POST, request.FILES, instance=request.user.profile) if user_form.is_valid() and profile_form.is_valid(): user_form.save() profile_form.save() messages.success(request, f"Profile successfully updated!") return redirect("profile") else: user_form = UserUpdateForm(instance=request.user) profile_form = ProfileUpdateForm(instance=request.user.profile) context = { "user_form": user_form, "profile_form": profile_form } if request.user == user: editable = True return render(request, "users/profile.html", context) Any help would be much appreciated.

Why can't I save my form data into a model db?
When I try to save the info inputted into the form, I get the ValueError: Cannot assign "<class 'auctions.models.User'>": "Listing.user" must be a "User" instance. I think that this may be because the model field Listing.user is a foreign key between the Listing model and the User model. Even when I change Listing.user = User to Listing.user = User() (includes brackets), it returns the ValueError: save() prohibited to prevent data loss due to unsaved related object 'user'. So how do I add who the current user is to the model field Listing.user? models.py: class User(AbstractUser): pass class Listing(models.Model): ... user = models.ForeignKey(User, on_delete=models.SET_NULL, null=True) views.py: def save_new(request): if request.method == 'POST': form = NewListing(request.POST) if form.is_valid(): obj = Listing() ... obj.user = User # this returned the first ValueError # obj.user = User() - this returned the second ValueError obj.save() return HttpResponseRedirect('/') -

¿Cómo comparar cada uno de los elementos de una lista con ellos mismos?
Tengo una lista en Python lista = [1,2,3,4,5,6,7,8,9] Quiero recorrer la anterior lista , pero en cada iteración comparar esa iteración con todos los demás elementos de la misma lista (incluyendo al valor de la iteración actual) para realizar una consulta a la base de datos y verificar si existe un valor , de lo contrario regresaría cero (0) suponiendo que estamos iterando en la lista: para la primera iteración que es el 1 ahí se debe iterar de nuevo todos los elementos de la misma lista para realizar unas comparaciones y la consulta mencionada anteriormente , y así seguido con la iteración 2, 3, 4 etc. Lo ideal es que esas comparaciones no llenen la memoria RAM o se ponga lento el programa, ya que estoy trabajando con Django 4. por eso no he intentado realizar bucles for Agradezco cualquier aporte que me ayude a solucionar este problema.
