Eloquent Polymorphic Relations: Properly Explained

One video from my course "Eloquent: Expert Level": laraveldaily.teachable.com/p/...
Polymorphic relations are one of the most difficult concept to understand for junior developers, and I tried to do it with a real-life example.

[@redward4383]

Thank you so much, i had this kind of issue,but wasn't aware that these relationships actually exist, you've explained it very well.

[@kevinnacario359]

Thank you so much!!! Was able to get the point of Polymorphic right of the bat. Definitely worth it. Hoping I could take your course but it seems its too expensive for me at the moment.

[@VadimBesedin]

As always - great explanation with examples. Thank you

[@reesss4]

This is by far the best explanation I have seen! Thank you!

[@shafqatalinawaz6218]

Thanks for sharing. I now understand perfectly how to use polymorphic relationships.

[@heitorferreira964]

Thank you, your explanation save my day, I was very confused at beginning and I watched this lesson and debug many times until got the trick how it works under the hood.

[@Hiltaku]

Thanks! Love the example. Makes the concept very easy to understand

[@wtalkie]

Great explanation as always. You're the go-to channel for anything laravel-related.

[@andywong2244]

i was able to get the concept behind polymorphism at the 1st 3 minutes of your explanation Povilas! you teach very well!

[@georgenikou]

Really well explained, thank you very much for this!

[@sofiatopalidi9403]

Thank you :)

[@anissmarrouch282]

i was confused on this i am doing it in rails its different code wise but im assuming its the same concept thank you for the video and for the excellent explanation

[@opentech5972]

That mechanical keyboard sound, satisfying.

[@asatbekxalimjonov4005]

amazing

[@vitaminabe]

thank you, very informative!

[@windigo000]

cool. 👍 i just can't bring myself to liking this aproach. one-too-many sleepless nights with slow db without keys. :) but it might have it's uses.

[@shubhamsahuSD]

Got it

[@ashique12009]

Nicely explained. So if we have 3 tables like posts, products and images then we can make polymorphic relationship to bring data in optimized way. This can be done if we create two photo tables one is for post_photos and another is product_photos but for polymorphic relation we can reduce one table here. Thanks.

[@andywong2244]

well said brother!

[@adnanasad4674]

Thanks, I have one question how will we reserve it means Photo::get() and It should fetch relationship data from relevant table example post or product.

[@SalmanMemon_Sam]

best

[@WaheedSindhani]

How do we retrieve all data with relations.

[@mikeendsley8453]

Excellent video… you just saved my butt! Do you have any Udemy courses?

[@PovilasKorop]

Thanks Mike. Not on udemy, but on teachable - see laraveldaily.teachable.com

[@NMND.]

AAAARGH SO BRIGHT! x_x

[@VadimBesedin]

But if my Models should have only one photo per record, having regular BelongsTo would be totally enough. Am I right? Posts ---id ---text ---image_id Users ---id ---name ---image_id Images ---id ---filename Or there are still advantages to use Polymorphic Relations in this case?

[@PovilasKorop]

If you have only those models strictly, then yes, your structure is good. But if in the future you're planning to have, for example, Comments with image_id or something else with image_id, polymorphic structure would allow you to achieve those new fields without changing any structure of DB cause you would reuse the same images database table.

[@twentxx]

Thanks very much, but this video not include Factories and Seeders

You are the best teacher ! From russia. putin-juilo

[@nahueljj]

how to update? i have Polymorphic tags, and i can store success but i cant update fine, the result contact the tags,for example #hello #word and i add , #one.. the result in my input is #hello #word #one #hello #word #one my code.. $tags_name = explode(' , ' , $request->tags_name); foreach($tags_name as $tag_name) { $post->tags()->attach(Tag::updateOrCreate(['name'=>$tag_name])); }

[@PovilasKorop]

What is the error that you're getting? Maybe you shouldn't to ->attach() but instead create things manually, like PostTag::create('taggable_id' => $post_id) ... etc? (not sure what your polymorphic model is called, assumg PostTag)

[@nahueljj]

Hi, thx for the answer, My problem is that I don't think I'm using the most optimal solution to update the registry, since I'm removing the tags with dettach and then adding them again ... es.stackoverflow.com/questions/418957/como-hacer-un-update-en-una-tabla-polimorfica,

[@PovilasKorop]

@@nahueljj I think it's fine.
