Laravel Eloquent: Deeper Relationships with One Query

If you work with a project that has multiple levels of hasMany relationships, you can use hasManyThrough instead, or one of a few packages I will show in this video.

[@martinh4982]

Hi Povilas,
In Eloquent is it possible to join to an arbitrary sql statement? For example, say I have a User model and I want to create a UserStats relationship. However UserStats is not a table, but a sql statement that computes stuff like last_login, number_of_posts, up_votes etc. The only way I've found to do this so far is with a database view that I manage with migrations, but was wondering if this could be done purely in Laravel.

[@GergelyCsermely]

Thanks

[@ChangeYourLifeForever]

by this video you can understand the principle of has_many and belongs_to in other languages and frameworks also

[@shofada]

Thanks or putting this together. If you had a page that needs to display say for every employee, the country, city and shop, what might the query look like?

[@AbdulMajeedShehzad]

Thank you for the great video, I've a question for this scenario. is it a good practice to use keys in deep relations ? for example in employees table we add country_id to avoid complex queries when working on reporting. I've been looking for this answer for quite a long time

[@kauandouglas]

Up

[@javieru5871]

Feel you bro, done the same: usign foreign keys to those deep deep relationships

[@ilyasabdut]

what package did you used to showing relation and through text in the model?

[@akintandavid2500]

Thanks for this how can i learn more about eager loading

[@Formula7Driver]

What if we want to update data? I have a Sales Order, with Items, and each item has a list of Operation IDs to produce the item

[@arashpirhadi1326]

great video thanks. :)
but i think in some situation like this performance will drop after 2 joins and more.
I mostly using DB facade for retrieving data from database.

[@LaravelDaily]

Yes, for complex queries raw queries are still the best.

[@insider-analyst]

composer require staudenmeir/belongs-to-through:"^2.5"
not installing on laravel 8

[@taghreedomer6208]

really helped me with retrieving data, but what about insert data? is it possible to do so?

[@patihuuu6288]

What about A -> many to many -> B belongs to -> X, is possible using this package to access X from model A ?

[@TechITWorld]

Could you make one video of belongstomany with three level deep query with where condition (with the last one)?

[@jimishukurow2286]

royal like from me!

[@dApoTB]

Thanks for your videos! Could you please do one about constructing relationships between tables that are in different databases and connection names to those tables cannot be hard coded. E.g.: User table is in DB1, Post table is in DB2 and Comment table is in DB3. Can we construct a relationship here? Thanks!

[@SonsParaRelaxar]

It will work the same, the only thing you will have to do is overwrite the connection variable inside of the model.

[@Ayvengo21]

All the time i see that orm magic like this I'm asking myself does it worth it or maybe some escaped sql would be way easier to read and write. Because sql knowledge could be transferred between projects while knowledge of specific orm might be problematic.

[@razin223]

You do not show how to set search filter with "with" relation and its deep level with multiple column. Can you do that?

[@NazmulHaqueroton]

Sir, @LaravelDaily If i want to add another table: shop_branches fields: 1) id 2)shop_id 3) shop_branch_name
then how i define relationship to access: shop_branch_name

[@salimtheone]

how can we select only some attributes of the second table?

[@erikgratz5539]

@ 8:00 you are showing off the functionality of `hasManyDeep` to associate employees with their countries. Could this also be achieved with an additional `hasManyThrough` definition? Where it is defined as `hasManyThrough(Employee::class, Shop::class)` ? Or do those methods not chain well / is this strictly better for performance?

[@yogeshwarbarai9686]

what ide setup you use ? It looks so good and to the point

[@LaravelDaily]

Phpstorm default

[@titon9688]

how to query with scope to show id 1 from shop ?

[@ugayashan8659]

Great content, can you make a video on user referral system using laravel Eloquent

[@ramdhannugraha99]

how to get all data of that relationships not through some. ex all countries, and all cities and all shop in 1 query, i wanna make tree.. pls advice sir

[@johnerrolprincipe8992]

Hi, I watched your video about function's return type, is there any documentation about the full list of return types? Thank you!

[@LaravelDaily]

Any PHP variable type or PHP/Laravel class could be a return type. There's no list.

[@adityas2753]

how to get limited relationship data with using laravel and mongo db please give me solution thank you
