Hello @salmanaligeek thanks for the report.

Indeed I can confirm that we added a function that is not supported in all Laravel versions that we support in CRUD. I see you are using Laravel 6. Sorry for the trouble, we will try to come up with a solution as soon as possible.

I think we can port that function back to L6 by using macros.

ping @tabacitu

Str::of does not exist in Laravel 6.

I think an easy fix is to add a macro in case it doesn't exist:

//GeneratorsServiceProvider.php

//check if method `of` exists in Str class, if not register it

Str::macro('of', function (..) {
// replicate laravel code for `of` function
})

What do you think ?

Best, Pedro

[tabacitu]

Ouch! Yeah we probably forgot we support L6 too... sorry @salmanaligeek !

Seems like this has happened in this commit https://github.com/Laravel-Backpack/Generators/commit/8597e4eed25d7b8d5fd8c07ef0cb9ed3ac37eb44 - when @promatik fixed stuff, he also started using the Fluent Helpers. I didn't notice it in my review, sorry. It would have been fine if we dropped support for L6 right then and there, but now that we have tagged versions with L6 support and Str::of()... we're forced to fix it and keep L6 support.

I don't think adding a Macro would be an easy way out... I expect it's not as easy as that to add Fluent Strings to L6.

I think our best bet is to rewrite those bits to no longer use the Fluent String Helpers, but normal String Helpers. Even though the code would be uglier, it'll support L6-L8 and fix the problem.

@tabacitu

I've just had a grip on this, and the macro part is just that easy:

// notice `off` because I am in a version where `of` is available
if(class_exists('\Illuminate\Support\Str') && !method_exists('\Illuminate\Support\Str', 'off')) {  
            \Illuminate\Support\Str::macro('off', function($string) {
                return new \Illuminate\Support\Stringable($string);
            });
        }

Problem is that in L6 there is no \Illuminate\Support\Stringable class. So yeah, in this specific scenario is better to just write with other Str functions, otherwise the macro would be just fine! :)

I will assign myself to this and fix it.

Thanks, Pedro

[promatik]

My bad, sorry 🙃

@pxpm I did the mess, I fix it 😅 the PR is here; https://github.com/Laravel-Backpack/Generators/pull/116

$nameTitle = Str::of($name)->afterLast('\\');
$nameKebab = $nameTitle->kebab();
$nameSingular = $nameKebab->replace('-', ' ');
$namePlural = $nameSingular->plural();

This was so beautiful 🤷‍♂️

@Keanhor2 I think in that migration you have a typo, and instead of $table->string() you have written $table->strong().

[tabacitu]

Strong columns are the best!

Sorry @Keanhor2 that has nothing to do with this thread. If you think it's Backpack-related, open a different issue. But it looks to me like it's got nothing to do with Backpack, but VueJS/Laravel. Cheers!
