build fail :(

[antonkomarev]

It's not completely failing. Laravel 5.4 is working. The main goal of this PR is add automated Laravel 5.4 testing. Return support of Laravel 5.3 and lower will be the next step.

[jampack]

so the main package is now 5.4 compatible? or is it dev-master that supports 5.4

[antonkomarev]

https://travis-ci.org/proengsoft/laravel-jsvalidation/jobs/251770946

[antonkomarev]

Only dev-master is supporting Laravel 5.4. And it's not supporting any older Laravel versions.

let me update and check i pray the array validation has been fixed magically

[antonkomarev]

@akkhan20 sure! I've just finished this PR. Waiting that all Travis jobs comple and ready for merge. We are waiting to have success result for Laravel 5.4 tests only!

[jampack]

the package is not generating the js rule for var.* => 'min:5|max:15' where as when i dug in previously reported issues i see the package owner stating that this issue has been fixed and functional in latest package

[jampack]

the rule in laravel is like:
'description' => 'required|min:30:max:500', 'tasks.*' => 'min:10|max:65500'

but the rule generated in js is:
rules: {"description":{"laravelValidation":[["Required",[],"Description is required",true],["Min",["30:max:500"],"Description too short(minimum 30 characters)",false]]}} })

@akkhan20 You'd better place it in proper issue: #253
