Ruby on Rails Tutorial Part 9 - Validation & Error Messages

[@TumblingPenguin]

It's crazy how clear and helpful some people are and how utterly confusing and frustrating others can be. I wonder how often people give up learning something, thinking it's too hard, when really it's just terrible teachers making things seem much harder than they are... You, sir, made this seem incredibly simple and, as a result, I learned a lot and feel confident that I can learn more. Thank you very much!

[@JayBowles]

I agree - this is by far the best tutorial I've come across. If you did another series I would happily pay for it.

[@jhunter34]

This is the best tutorial for rails I have found. I was hoping you were going to get into other data models to show how you define the relationships, but I really appreciate what you've done here. Thanks!

[@dealloc]

I've always wanted to learn Ruby but never really got to it. Your videos makes it painless and I now realize that it's easier than I thought. I already do a lot of other languages, but RoR just makes making applications and websites easy and fast. Thank you, Andrew - I hope you upload more videos :-)

[@codemaker38]

At first I had thought that RoR is so complex that its makes me lazy to study it, but with your tutorial its makes me wanting more to dive on it. Thanks =)

[@MegaKittenzz]

Hi, I just completed the series and I just wanted to thank you for the videos! They're super awesome!! I've tried to learn rails several times and I was always frustrated but now I understand the basics thanks to your effort!

[@Burkaz0id]

Thanks for these videos, they actually helped me understand RoR much better than one of the book tutorials :)

[@Iain0101]

Andrew, thanks for posting this series. I have followed through your CakePHP and Rails tutorials and find them easy to get started with.

[@nikinjain1]

Thanks a lot, These videos helped me understand RoR much better than few of the famous books

[@ammsa7]

Thank you very much for this series! I wish it was longer, please do more tutorials on ruby on rails, your tutorials are clear and easy to understand :)

[@mjhamm1975]

I just watched all 9 videos and they were extremely helpful. Thanks for the time and effort. Cant wait until you finish some more of them.

[@thusithaniroshan]

If I found these tutorials before one week I will definitely complete my assignment . but it really useful for future studies. really learnt a lot about Ruby on Rails. how MVC works and many more things . two thumbs up dude. keep up the good works. this is good for non scaffolding users. gives deep explanation. really great stuff. (y)

[@9vg80zm4lybt0kb]

Hey Andrew, fantastic series. You should really have a site dedicated to these videos and a donation button, I'd gladly pay for more.

Thanks for a great tutorial series! Like the other viewers have mentioned, it would be really great to see the 10th video.

[@PowderkegHQ]

Keep the tutorials coming! These are great. Would love to learn more about version control and security, too. Thanks, Andrew!

[@willandheidi]

Thanks so much! This is the best beginner Ruby on Rails screencast series I've watched. Are you planning to do more Rails screencasts???

[@adebcfc885]

Excellent quick, concise and very well explained tutorial - Andrew, you should be writing books mate!

[@rodd91]

thanks a lot. helped me finished my homework in 2022. spent days trying to get the error message for blank fields. 😂

[@andrewperk]

Hey no problem. Glad it helped, even after all these years haha.

[@DillonBenson93]

[@abhilashreddy]

[@avattathil]

Andrew, This series has been very help full. Thank you.

[@majestade2345]

Great videos!!!! I just finished all 9 tutorials and it was great!!!! I fallowed some tutorials.... but i always ended up with error that i don't know how to solve.... in here i had some minor issues (strong_parameters) but it was not that hard to solve! Hope to see video 10 and more videos explaining how to add and connect more resources!!!!

[@andrewperk]

@Burkaz0id You're welcome, I'm happy they were helpful. I'll be working on the rest of the series this weekend. So I should have a few more videos up with in a week.

[@gaganremba]

All tutorial is awesome. please upload 10 tutorials

[@tonato911]

Thank you for the videos, but i would have liked to have seen the ten part, to see how the DRY principle was applied to the new and the update methods. Anyways thank you so much, by this videos I was able to see what RaR is about, thanks! ( :

[@vukky]

Thank for the tutorials, it really helped my to start with RoR. Hope you make more lessons soon. Cheers

[@FreeNextGen]

great vidoes, would like to see more RoR stuff with different kinds of projects.

[@SergioBarreracoding]

Great RoR tutorial! Thank you Andrew for sharing your knowledge!!

[@nguyenong1567]

thank you andrewperk! pls make more Rails tutorials

[@yanmyoe]

Thank you so much Andrew. Now I got basic knowledge in ROR. !!!

[@Royals189]

I cannot like these videos enough!

[@andrewperk]

@mjhamm1975 Its called snippets, you enable it in plugins under preferences, then under tools you can edit and add new snippets.

[@MrKarvalhovsky]

Great video tutorials! I hope you upload more... Thank you Sir!

[@andrewperk]

@tonato911 I'm sorry I haven't had the time to make more videos and complete the series. A few things you could do to dry this code out would be using partials for the new and edit forms, a partial for the form errors, and by using a before_filter to declare the @post = Post.find(params[:id]) on the show, edit, update, and destroy actions, then you could remove this variable declaration from each action to remove code duplication. Thanks for watching.

[@laylock]

These tutorials have helped me SO MUCH. Thank you!

[@tommy88c]

Thanks for the all vid they ware really helpful but can you tell me what plugins do you use in your gedit? Especially the one that colors ruby better and the one that fill the rest of the html code.

[@tinodefaultino6732]

hey Andy! many thanks man for the videos.. really cool stuff to get started with ROR :)

[@nikhilfadnis8009]

[@stepsalin]

[@edgargutierrez9434]

Where are we on vid number 10 Andrew? Great vids!

[@RafaelDias496]

You'll have to part 10 of the Ruby on Rails tutorial ?

[@JosephWeinerE]

Very helpful thanks! One think on rails 2.0.0 I commented out this line #attr_accessible :url, :name url and name are the two fields I am using on my form, you would have :title and :content Don't know why rails was barking at me but I take out that line and it works!

[@JosephWeinerE]

Also my form, created by my scaffolding, automatically put out error messages as soon as I added the validation, didn't need to write the code.

[@aigulimadildayeva8348]

gr8 video, thanx! Maybe I am mistaken, but this will not work without configuring posts_controller. So I would also add following command: def create @post = Post.create(post_params) if @post.valid? redirect_to posts_path else render new_post_path end end

[@dasten123]

EXCELLENT tutorial, really!!!!

[@mjhamm1975]

What is the plugin you are using with gedit to autocomplete the html? thanks for the help.

[@annabortsova]

same here, thanks again !

[@gadamson12]

How would you require a login to create, update, and destroy posts?

[@derSchmidi]
