You've got a really nice knack from explaining things clearly in simple and straight forward language. Thanks very much for you tutorials. Great work.

[@CodersTape]

Thanks

[@axeman2638]

@@CodersTape ,Thank you, I've been following your Laravel tutorial series, I think it's better than the laracasts tbh. Better structure and logical flow from concept to concept and more clearly explained. The laravel documentation is pretty opaque as well and I've not found it of as much help as your stuff. Cheers, keep it up.

[@Chmelewsky]

this is one of the best laravel tutorials i've seen. subscribed!

[@dopplereffect7325]

Please I want to thank you for all the tutorials you have put on KZbin ,the way you explain is great. What you put here is the best of all I have had before. Udemy courses cost a lot in my currency ,having this kind of content here for free I what I can't describe, thanks personally you been of great help to me ,keep going ahead

[@pavanobhan1105]

You are awesome. I was having hard time understanding the relationship concepts through documentations. After watching your video, now I have crystal clear idea on relationships. Thanks a lot. Subscribed.

[@JiteshDhamaniya]

You are a hell of teacher mate. kudos to your efforts. on side note - in this tutorial you said "able" as in imageable is reserved and you must use it, which I believe is not the case. you can really use any name as far as you using same function name in morph model. Like If you using nice as function name for returning return $this->morphTo(); you can then use column name accordingly like nice_id and nice_type and this would work too. public function nice() { return $this->morphTo(); } and then you use nice_type and nice_id, in place of imageable_type and imageable_id.

[@feranmiafrica9528]

Just when I've thought I've know all in laravel this came up.. Victor thank you for your efforts in making us how we are today... May you continue to grow in knowledge, wealth and in good health 😍 like if you love VICTOR

[@CodersTape]

Thanks! All the best!

[@colinrdixon]

puts it all into perspective!! super appreciate you for this video.

[@RecklessCoder]

Great Video! Only thing I'm missing is the Relation::morphMap which can be configured in the boot method of the AppServiceProvider. That way the namespaces won't show up in the database like 'App\\User' but for instance as 'user'. That way, when a model gets moved to another namespace you don't have to write migrations, but just change it namespace in the AppServiceProvider.

[@CodersTape]

That's a good point but to be honest I have never had to move a model from their original namespace. Did you have a need to move a model's namespace in a project?

[@RecklessCoder]

Coder's Tape yes. Currently I’m working on very large projects. Very often we move models from the models-namescape to modules where they belong. The morphMap then comes in handy

[@CodersTape]

@@RecklessCoder that sounds like a great use case.

he scripted before and maybe done this at least once(or not) depending of how complex is the concept. I don't like that personally but he explains so well the concepts, a lot bettern than me, but i don't script anything.

​@@ProgrammingwithPeter yes, he saved a lot of time for watchers, you should learn about this, just personal opinion 😁

[@ProgrammingwithPeter]

@@hieunguyenac4675 I know that he saved a lot of time for the viewers, but i just don't like this style, i always tried to find someone who builds real projects, even if it takes a lot more time, i can learn more and see the flow of developing, that's why i'm doing it right now myself. But, there are more people that prefer scripted . It's not my style. But again, I'm doing a different thing, he teaches you concepts, i build projects

Mistake is the key of understanding when ever you did mistake in things you will understand that more than the others, that’s why every programmer should learn how to solve mistakes which in the language call debugging. And I am a programmer as well but I love to do some mistakes when coding just to disturb my brain 🧠

Can you please guide and build a similar video on the business model of "User", "Address" and "Company" tables. Scenario here is that 1. an address can belong to a user and at the same time belongs to a Company, 2. a company can have many branch address and 3. a user can have many billing address (like an amazons many shipping address). In an market place there are many user so a users can be a vender with business address and user can have an non-business address who does not belong to a company and is a buyer in that marketplace. Requesting you to please structure it. As this is three way relationship explanation needed. I believe this video will be very help full to me and to many others. !!!!!

[@patrickgomes2261]

I think having different tables when you have a big website would be better to maximize the time... Imagine searching in a table with comments from posts, videos and other things all together... Of course you can take based on the type but even though I think it would take more time than a separated table

[@sumitwadhwa8823]

excellent video. btw, performance-wise, what is more suggestible as the application grows: polymorphic or multiple association tables?

[@Patrickdaawsome]

Do you have a suggestion on keeping order of images of a One-to-Many relationship? Let's say a post usually has a header and footer image. Would you add an incrementing integer column and use code to check it 1 or 2 (like an enum) or would you have a better way to implement this?

[@graceresourcecentre1200]

Thank you for this tutorial , just follow-up question this type of relationship is reliable enough? vs the common relationship practice ?

[@milospetkovic9927]

Great video/tutorial! I have a question regarding a database query performance. The database column "imageable_type" can't be used as foreign key to an appropriate table because it's used for different models. How it will work in case of many database records when foreign key/index is missing? Is it better to have a separate image table for each model in that case?

[@SabinSipai]

first of all thank you for explaining so beautifully. Can i ask how do you fetch the data according to tags? i.e. show video according to tags and show post according to same tag? Thank you for making this video

[@kisstamas6675]

hi! thank you for that video it is awesome! I have some question: What if that morph tables (comments, images, tags.) contains a lot of records? Does the queries will be run slowly? Thanks

[@ronssijei]

What about creating a history of user's payments and visitor's visits? Is the morphing a right way to do it?

[@josibee]

At 8:25, if you run $user->image()->create(['url' = > 'profile.jpg']); you will have more images for the user. How do you make a constraint that no record should be created for the user if one already exists?

[@SethSetiadha]

When is the best time kr what case is best practice to use polymorphic?

[@md.imrulhasan8757]

In 8:50 You said, "So this image can not belong to more than one 'User'.". What does it mean? Is it mean a profile picture with a unique URL can not be used by more than a user? I query it. But it creates a unique image URL with two users. Do you clear me out?

[@ehSamurai3483]

So if 2 tables is related to one table, we create a polymorphic relationship right?

[@SaranshDhingra]

Hi! Great Videos :) Can you also include a video related to "Creating a custom queue driver", like instead of using DB/SQS/RabbitMQ we use filesystem or something else. I have a use case that I need to create one using STOMP from Amazon Mq, but there is no proper documentation on how to create one. Not even a package that works properly.

[@vahidabedi9534]

Tnx for your great videos. I have one question. What is the advantage of using polymorphism over using the scenario below: images table: -post_id -user_id ... (and we fill just one of the id columns based on use case)

[@stevenstraker5105]

This is another way of doing it, however, this requires specifying a column for individual relation. Polymorphism allows for dynamic relationships, so the database doesn't require changing each time a a new relationship type is added

[@mememedia4788]

Hi, What's the best way to create custom functions/helpers/library in Laravel?. Where can I write codes for reusable functions such as SMS notifications and other API calls to use in multiple controllers. If possible please make a video about it.

[@codingstuff8305]

Hi Victor. Just a question for being sure... If my models are in a dedicate folder name Models for example do I have to put the full name space of a relationship declaration?

Yes. Or you’ll have to import the class up top with a use statement.

Hey guys, please assist me on the following: I have 3 models namely User, Lecturer and Student I want Student and Lecturer to extend from the User model. Is it something like Student and Lecturer belongTo User ?

[@JiteshDhamaniya]

Relationship is about Join in SQL.

[@stevenstraker5105]

I know this is quite late, but just in case (and for anyone else coming along), what you're referring to is class inheritance, rather than database relationships. Relationships would be more like a Student and their Classes, rather than a Student being a type of User, if that makes sense.

[@christiansenmarcus]

Excelents videos Victor, I have a question a litle bit diferent, how to handle the laravel version upgrade in your app?, suposse you have large app maked in laravel 5.5 and now you want to use laravel´s version 6

[@CodersTape]

When upgrading from version to version, you will need to follow each guide and make the necessary changes from 5.5 to 5.6 and then from 5.6 to 5.7 and so on. There’s also a service called Laravel Shift which does the upgrade pretty automatic for you but it costs money. Might be worth looking into it.
