Django template variable string as html
I've written a small view which contains some html embedded into one of the list arrays. When I use that list item in a template, the data is interpreted by the template as a literal string rather than html.

Keep input order of ModelMultipleChoiceField with Select2MultipleWidget
I have a many-to-many field in my model and I am using a Select2MultipleWidget to search values for input, but after selected the values are being sorted alphabetically as it seems.

Django - on checking checkbox add model to M2M relationship

Redirect Login Form To SSO Depending On Email Domain
As a bit of a hobby I am making a site where I want users to be able to login with site credentials or a SAML SSO (Azure AD, but maybe some other SSO providers in the future). I am using Django for the project. I am planning to create a second page which handles SSO (I am planning on using django-saml2-auth to facilitate that). However, to make it slightly easier for users I want to redirect them automatically to the page if they input user@example.org into the username field. People using SSO would only come from that domain and would be expected to use SSO to login. As some users would still need to login with regular credentials I don't want to force SSO using django-saml2-auth. I've seen quite a few services do this and I am thinking a little bit of JavaScript is all I need (as no sensitive/important/critical information is being transferred it shouldn't be bad if it is client side) to redirect them to the SSO page. Would any of you be able to point me in the right direction on this? Sorry if there is a question like this already - I couldn't find one. -
Django - Dependant Dropdown Filter without using ForeignKeys
Is there a way in Django to create a dependant dropdown menu without uisng ForeignKeys? Lets say I have the following model: class CSV4(models.Model): var1 = models.CharField(max_length=100) var2 = models.CharField(max_length=100) var3 = models.CharField(max_length=100) var4 = models.CharField(max_length=100) var5 = models.CharField(max_length=100) var6 = models.CharField(max_length=100) var7 = models.CharField(max_length=100) var8 = models.CharField(max_length=100) var9 = models.CharField(max_length=100) So var2 should be dependant on what was selected in var1 and so on. I tried this in my filters.py and the filter works, it is just not dependant: class CSVFilter(django_filters.FilterSet): entries = CSV.objects.values_list('var1', flat = True).distinct() var1_choices = [(e, e) for e in entries] #print("e" , var1_choices ) var1= django_filters.ChoiceFilter(choices = var1_choices ) entries = CSV.objects.values_list('var1', flat=True).distinct() var2_choices = [(e, e) for e in entries] var2= django_filters.ChoiceFilter(choices=var2_choices ) var3= CSV.objects.values_list('var3', flat=True).distinct() var3_choices = [(e, e) for e in entries] var3= django_filters.ChoiceFilter(choices=var3_choices ) var4= CSV.objects.values_list('var4', flat=True).distinct() var4_choices = [(e, e) for e in entries] var4= django_filters.ChoiceFilter(choices=var4_choices ) And in the template: <form method="POST"> {% csrf_token %} {{ filter.form }} <button type="submit">Search</button> </form> <ul> {% for i in filter.qs %} <li> {{ i.var1}} - {{ i.var2}} - {{ i.var3}} - {{ i.var4}} <a href = "{% url 'appp:edit_results' i.id %}"> <button>Edit</button> </a> </li> {% endfor %} </ul> So I have … -

Django 2 Reference multiple users into one Model
I'm working on a project using Python(3.7) and Django(2) in which I have multiple models using the User model.

Django: get id of object with only one field
I've a model Cart that has 2 fields, I'd rather change these 2 fields and keep only date_added. Right now I cannot do it because I use the cart_id field to create the Cart object and extract it's id: cart_id and date_added class Cart(models.Model): cart_id = models.CharField(max_length=100) date_added = models.DateField(auto_now_add=True) class Meta: db_table = 'Cart' ordering = ['date_added'] def __str__(self): return self.id In my view.py, I'm just creating the Cart object with the cart_id field as Random. This only to create this object and after that, obtain it's id, to replace "Random" with the id of the Cart recently created. This is not DRY at all. cart = Cart.objects.create(cart_id="Random") cart_id = cart.id How can I avoid this unnecessary step? -
Django project students will add new template files and fix permissions automatically
I am currently making a Django website for my school. On the website, students will have their own web pages linked on the main site that only they can access. My question is, therefore, the best way to approach this so that only people with access can access the students' web page. The biggest problem with this is that students will have a different amount of template files. My goal is to do this automatically so that they never have to add something in the source code when adding new web pages. I have something right now that is using groups and checking if a certain student has the correct group that goes with it and using URL dispatcher to do it automatically. Current url: -
