laravel-collect | laravel collect （用于收藏功能的扩展包）

Hi I have a lot of Eloquent queries in foreach loops all over my app and I am trying to avoid this practice where possible.

Example:

i'm fetching data from database and want to make dropdown list with one value selected by default

i tried this Laravel-5 how to populate select box from database with id value and name value

but nothing happen

my view file:

I want to remove some attributes from the final result and found this here Get only specific attributes with from Laravel Collection

This works for the top level but what is need is to remove some attributes from a related item say user has one access_card and access_card have some long text details as one of its attribute.

i want to remove that attribute from final result. Is is possible with the method mentioned in link?

Laravel's Collection class (v5.5) has a sortBy() method that sorts everything similar to if you had used a SQL ORDER BY statement, except there is one striking difference: a relational database will put NULL values at the end when sorting ascending (or at least PostgreSQL does), but Laravel's sortBy() method puts NULL values first.

So how do I get those NULL values to be sorted last instead of first when using the Collection::sortBy() method? PLEASE NOTE: I cannot change the database query itself! MY ONLY OPTION is to sort the Collection itself within PHP. I absolutely cannot do this at the database level in my situation.

There is a similar question on Stack Overflow here but the solution OP found was kind of a hack and does not work in my situation, because I need it to work for varchars.

NOTE: I realize sortBy() accepts a Closure for the first argument but there is zero explanation in the documentation about the arguments this closure receives (which "key" is $key?), nor does it explicitly say what the closure is supposed to return in order to determine the sort order. (I'm assuming it should return an integer representing the order, but I do not know how to make that work for me with multiple NULL values.)

I wish to make searchable box using Jquery Select2.js in Laravel-Collective code.

This is when before adjust select2.js

I am a newbie in Laravel Development.

I want to display JSON Beautify Formatted Result on the WEB Page.
