an excelente tutorial bro you illuminated my mind thank you so much

[@FririkurEllefsen]

Thanks for the tip about using the ForElse loop and "empty". I will rewrite some of my code and use those instead of numerous IF's

[@codewithdary]

Yes, it helps a lot!

[@kemal6039]

If you're having "Foreign key constraint is incorrectly formed" error, do these : 1 - On the migration file, change the type of your foreign key to unsignedBigInteger from unsignedInteger 2 - Make sure the table that foreign key belongs, is being migrated before the table(s) with foreign key. You can accomplish this by renaming its migration file, for example change the "2022_" in the start of the name to "2001_"

So much easier to understand, thanks. To build on your example of cars and car_model how would you automatically insert default 'name' with lastid create from cars table?

[@sirbangalot569]

It's funny how I tried looking up adding foreign keys online and would always get an error...them booom💥 I do your tutorial and it works. Good work man, can't thank you enough

Always good to read that! Thank you for your kind words man!

[@agafonovas]

Love your videos man 😮

[@codewithdary]

Thank you

[@tech-trials]

At the end of this video i used '{{ $model->model_name }}' and it worked for me dunno if thats cuz i used a separate migration for carModels instead of adding it into the cars migration

[@codewithdary]

You can’t access arrays with the access operator [->]. It only applies to objects. But you can use the brackets to access an array. It just depends on how you pull out data from your database. If you var_dump your array, you can see what if it's an array/object/collection

Hey, lets say we wanna insert to the carModel table, do we have to create the controller for it aswell? Or is there another laravel magic to make this easier? Great tutorial btw!

[@codewithdary]

Depends on what you want to do with the carModel, but in most cases nope.

Hi Dary thanks for the amazing videos about laravel. I have been facing something I don't know how to write the query in Laravel for it. I have two tables (users & user likes) users has two columns( id, name ) and user_likes has two columns ( user_id, liked_user), how can return all the users in users table except those users that the user has already liked them in Laravel? Please! for example: user 1in users table, liked user number 2 & 4. he can see all the users except user 2 & user 4. and so on for the other users. Please help

[@chukwuebukaohaji5285]

Hello Dary, nice video. I followed everything you did word for word (though different names etc) but I keep getting an error "Invalid argument supplied for foreach()". Please help out..

Yes!

[@rajabhishek2936]

Nice video

[@codewithdary]

Very nice

[@JohnSmith-zl8rz]

what's the goal to "protected" the table and the "primary key"?

[@codewithdary]

the property or method can be accessed within the class and by classes derived from that class

Hey guys ! I have a question about the tables, basiclly I have a table let's say its about countries.... to insert the name of the country and population, and i also have a table that has more detail about that specific country (president,size). Here is the problem, i made a form to insert the president name and the size in the table with the details, but the foreign key here is the id of the first table...how can i make tell the form or to the controller that i dont want to let anyone to insert the id, and also to let laravel know that the id of the countri is in the url and i dont have to insert it i hope you guys understend, also... sorry for my bad english.

[@mariuszdabrowski307]

what if I want to create a new car model with the form. I have to get car_id from somewhere. my idea is to create a private variable in the controller. I set its value in the store (id) method but if I check its value in another method I wrote storeModel (). then its value is null. help please

[@codewithdary]

One way of inserting related table is using relations as: $user = User::create($user_inputs); $xyz = $user->xyz()->create($xyz_inputs); It will automatically fills the user_id in the xyz table.

Hello, nice video, i wanted to ask you, if you could make a video how to synchronize data from checkboxes to database (i have issue when i want to insert an array of values into database from checkboxes, i want to automatically delete the unchecked checkboxes values from database) i was trying to search for it but couldnt find any solution, thank you for reading this.

Thanks for the idea!

[@carlfranz6805]

Um. How do we get to the 'show' function? I keep getting a 404 not found. [edit] Never mind, fixed it, although I didn't figured it out (this is, I've no idea how I fixed it). I'm getting better at debugging this mess, I guess.

[@codewithdary]

Keep working on it, debugging is such an important topic when it comes to coding!
