Is there a way to customize authentication views that are included in URLConf?
In Django 3.0 documentation, it is said that the easiest way to implement authentication views is to just "include the provided URLconf in django.contrib.auth.urls in your own URLconf". Is there a way to modify some attributes of these class-based views without explicitly referencing them? For example, if I want to modify the extra_context attribute of the LoginView, is it obligatory to handle it as documented: from django.contrib.auth import views as auth_views from datetime import datetime urlpatterns = [ path('accounts/login', auth_views.LoginView.as_view(extra_context={'title':'Log In', 'year':datetime.now().year})), ] or is there a shortcut for modifying this view in the included URLConf? -

custom css switch does not run javascript function
I have a custom switch in CSS that I am using in a template for django. I am loading the javascript file properly but when I go to use the switch I don't get the expected result. The expected result is that the background would change colour this does not work using the switch. I added a button into the template to see if the button would work which it did, javascript file: function myFunction() { var element = document.body; element.classList.toggle("dark-mode"); } HTML switch this does nothing: <div class="onoffswitch" style="position: fixed;left: 90%;top: 4%;" onclick="darkMode()"> <input type="checkbox" name="onoffswitch" class="onoffswitch-checkbox" id="myonoffswitch" onclick="darkMode"> <label class="onoffswitch-label" for="myonoffswitch"> <span class="onoffswitch-inner"></span> <span class="onoffswitch-switch"></span> </label> </div> HTML button that does do what is expected. <button onclick="darkMode()">Toggle dark mode</button> CCS if this is causing the problem: .onoffswitch { position: relative; width: 90px; -webkit-user-select:none; -moz-user-select:none; -ms-user-select: none; } .onoffswitch-checkbox { display: none; } .onoffswitch-label { display: block; overflow: hidden; cursor: pointer; border: 2px solid #000000; border-radius: 20px; } .onoffswitch-inner { display: block; width: 200%; margin-left: -100%; transition: margin 0.3s ease-in 0s; } .onoffswitch-inner:before, .onoffswitch-inner:after { display: block; float: left; width: 50%; height: 30px; padding: 0; line-height: 30px; font-size: 16px; color: white; font-family: Trebuchet, Arial, sans-serif; font-weight: bold; box-sizing: border-box; … -

Inheritance from an AbstractUser based Model in django 2.7
I have a Custom User Model extending the AbstractUser and it works fine. But now i want to create another Model that is extending my Custom User Model like this in models.py: class CustomUser(AbstractUser): phone = models.CharField(max_length=10, null=False, unique=True) town = models.CharField(max_length=25, null=False) class DeleveryPerson(CustomUser): code = models.CharField(max_length=10, null=False, unique=True) The problem is that the table DeleveryPerson is created with just the field "code" when I expected it to also have fields coming from the CustomUser model. So how can i achieve that kind of inheretane between CustomUser and DeleveryPerson. Thk! -

How can i import my data frame from pandas in my template , i work with django, in order to display some éléments to user
I started a projet in django and i have some question. I have in my computer 100 files tab extension, and each one contains between 20,000 and 50,000 rows and 53 columns. That is an very big quantity of data. I implemented a template which will display to the user the name of the different columns, and so the user will check the name of the columns he wants to keep. After having selected these columns, on the server side, I have to recover these columns in each of the 100 files. Next, consider that each file corresponds to a vector, and that the elements of the vector correspond to different columns. Thus, When the user has selected the columns he wanted, this vector will correspond to an entry in a machine learning algorithm (for the moment, the choice of the algorithm does not interest me). What is the best way (in terms of complexity) to use my data (the 100 files), read it, merge columns, and more ..., in my django project? What I have done so far: _I have recovered my files in the form of dataframe using the pandas library. In this form and thanks to this … -
