Tutorial is right to the point, focused. I am practicing all example given in angular js in your channel. Writing each one and trying out myself. Thanks for sharing them.
While trying out these examples in this video I noticed couple of items being overlooked
1. In app8 module search string 'studentName' was not referred any where. May be it was intended to use a text box with ng-model having 'stedentName' to filter by user input
2. While saying about filters (weatherFilter) in app8 module, speaker should have gone back to app8 module to refer how filters are added (linked) to module.

Thanks Derek for all the efforts, I sincerely appreciate it.

In 39:23 you add an extra '});' that breaks the code
you also forget to mention to inject the weather filter to the module in exam8.js file

These are some of the best tutorials I have found on AngularJs! Thank you so much for these!

To everyone trying to follow,
at 19:27, if you try to click on "Save" and it keeps refreshing and the list gets back to just one user. I spent almost 2 hours trying to figure it out and it turns out when you auto fill forms in visual studio code or any text editor for that matter and it gives you empty strings attribute there is a potential error. I DELETED THE EMPTY ACTION = "" attribute and it worked :(

Thank you so much btw,

Sorry if this has been covered already... but the custom filter only seems to work when it's part of the app8 module. If assigned just under angular.module ("weatherFilters") context, I get an dependency injection error thrown by angular. What am I missing here? Otherwise, *amazing* tutorials -- all of them! Thanks, Derek! Huge fan.

Many thanks Derek

27:32 App 7

// Create an instance of the parent controller
 childCtrl.child = $controller('mainCtrl', {});

So why would he reference the parent controller as a child of the childCtrl? I am confused by this example.

[mralextacy]

Good tutorial. One thing I dont understand, why do you have two controllers with the same name? Would this method work if the two controllers named differently?

[vikaschauhan]

this tutorial is very useful for me big thanks to derek,
one more thing in this tutorial the last practice of whether filter i got an error

[belmiris]

You make it look easy... too easy. Thank you for the tutorial!

[adrianmobley]

This is just what I needed. I've been looking for good videos on form validation in Angular 1.x

Hello Derek,
At 34:42, you mention 'studentName' as filter. Looks like you forgot to consider it as ng-model

[JanneRoos]

At 40:00, why is the filter set up the way it is? Why do you have a function that returns the value of another function that returns a boolean? Why not have the first function return a boolean? I've tried this and couldn't get it to work, but the question is why? Great tutorials nonetheless, very informative!

[sachittandukar]

Amazing tutorial!
Will you please consider making tutorial for angular 2?

[Klivdx]

Great tutorial as usual, I wish you can do another with advanced techniques and best practices, such as avoiding $scope soup, etc..

Thank you!
