Django Tutorial: Models, Admin Integration & Dynamic HTMX Updates—Python Fullstack Web Development—7

In this video, you’ll learn how to build the backend and user interface for creating, managing, and interacting with custom movie lists. In this video, we cover: 🔹 Custom Models (models.py) Build a UserList model to let users create multiple movie lists and a ListItem model to store individual movies. 🔹 Setting Up Relationships Use ForeignKey and on_delete=models.CASCADE to establish one-to-many relationships between user lists and list items. Ensure data integrity when a user or list is deleted. 🔹 Admin Integration Register the new models in Django’s admin panel for easy management. Use Django’s TabularInline to manage list items directly from the admin interface. 🔹 Dynamic Forms with HTMX Create forms using htmx attributes (hx-get, hx-post, hx-target) to add movies to lists without reloading the page. Handle form validation and display errors dynamically. 🔹 Conditional Rendering & Access Control Use Django template tags to conditionally display edit and delete options only to list owners. Protect routes with @login_required to restrict access to authenticated users. and more... 🔗 Github Links: Starting Code ( if you would like to code along ): https://github.com/PikoCanFly/Django-and-HTMX-Course-Series-Movie-Spot/tree/part-6 Final Code ( for your reference ): https://github.com/PikoCanFly/Django-and-HTMX-Course-Series-Movie-Spot/tree/part-7 ⏱ Chapters: 00:00 - Objective the functionality we'll add to our Django Website 00:16 - Why will use HTMX in this project 00:31 - Other things we will learn - How to add protected routes in Django Website to keep non authenticated users out 00:55 - What we are working with 01:14 - Bootstrap and HTMX 01:23 - What are Django Models | models.py 01:49 - Foreign Key Relationships (Defining UserList Model) 02:55 - Verbose Name + on_delete = models.CASCADE 03:11 - Character Field + Max Length 03:30 - Date Field ; automatically save creation date ( auto_now_add=True ) 03:47 - Creating List Item model ;Many to One Relationship with UserList Model 05:43 - String Method in Django Models `__str__` 06:52 - Update Database : Make migrations and Run Migrations 07:52 - Register Models in Admin Site ( admin.py ) 10:33 - django Admin's Tabular Inline - Adding List Items to User Lists Inlines 11:45 - Adding a new none Nullable Field to Django Model 14:19 - Create a place for users to browse their list ( User's Hub / Profile ) - Define Profile View 15:04 - Make it so that unauthenticated users can't get to profile page ( @login_required ) - Login Required Decorator 16:46 - Profile Page Template ( profile.html ) 17:12 - Map to Profile View 17:50 - check if route is indeed protected and unauthenticated users get redirected 18:18 - Get a hold of user lists and pass them to template ( add to context dictionary ) 18:48 - Loop through User Lists in profile.html 19:27 - Capitalize Username ( Django's capfirst Template Filter ) 20:31 - Create Add List Button 20:46 - Create List Form ( forms.py ) 21:22 - Subclass ModelForm class and link Form to Model with class Meta 22:06 - Make Form Appear Dynamically on Button Click with HTMX 22:41 - Make get request on button click with htmx ( hx-get ) 23:11 - swap inner contents of div ( hx-swap and hx-target ) 23:48 - Define Create List View & pass in form 24:20 - Create a partial template for Create List form 25:39 - Create Path to Create Form View ( urls.py ) 26:15 - Testing our Add to List Button 26:30 - Add type submit button to Create List Form 27:13 - Have the form make a post request create list view, and dynamically update the list ( why use htmx : hx-post ) 28:03 - Create User Lists Partial Template and take utilize htmx's swap strategy to dynamically update content 29:10 - Django's include tag 29:54 - Add hx-target and hx-swap htmx attributes to create list form 31:21 - Project against CSRF attacks ( add CSRF Token to Post Requests ) 30:30 - In views.py get users input, check if form is Valid, and save list to Database assigned to the logged in user 31:48 - Display Updated User Lists 32:40 - If form is invalid - return the form again with error ( status = 400 ) 33:01 - Testing our form 33:52 - Finally discovering that Prettier ( my html formatter VSC extension ) messed up my Django template 34:01 - Add Bootstrap Styling to our Page ( styling the user lists list ) 35:12 - Add Delete List Button and style it with Bootstrap 35:43- styling form with Bootstrap 37:11 - Dynamically Dismiss the form on Submit 38:28 - If user is authenticated display link to profile page in navbar 40:42 - Test if link works 41:00 - Final Remarks Join this channel to get access to perks: https://www.youtube.com/channel/UC8NoIbiu78iGMnh_xezgx8A/join #django #FullStack #HTMX
