supportsSchemaTransactions() is not a core method.

[kashtanoff]

this method used in laravel/framework/src/Illuminate/Database
/Migrations/Migrator.php

i have problem from this commit https://github.com/laravel/framework/commit/7a35d728582bdf33a335f82a37cb4bf52cb598d2#diff-a66c98fc0ca13ef8851970c40f8342d1

Hi @kashtanoff ! Facing the same issue you're having, I dug into the framework a bit and replaced
$grammar = $connection->getSchemaGrammar();
(rather, added) with this:
if (is_null($grammar = $connection->getSchemaGrammar())) { $connection->useDefaultSchemaGrammar(); $grammar = $connection->getSchemaGrammar(); }
you should be able to use rollback after doing so.
I know it's hacky as of the moment(and that it should be fixed in the future) but it worked for me.

Hope I helped you out on this! 😀

@kashtanoff do a composer update now, they fixed it already 😀

I'm using latest version 5.3.19 but I'm still facing this problem when using a custom connection (mongodb) in my migration class.

I've used jenssegers/laravel-mongodb as my mongodb package.
Before upgrading to the 5.3 it works fine but now after upgrading to 5.3 when I try to migrate my mongodb connection migrations class, the following error occurred:

PHP Fatal error:  Call to a member function supportsSchemaTransactions() on null in /private/var/www/laravel/vendor/laravel/framework/src/Illuminate/Database/Migrations/Migrator.php on line 378

class CreateLogTable extends Migration {
    protected $connection = 'mongodb';
    public function up() {}
}

@ellej16 #15892
$connection->getSchemaGrammar() still is null!

Can anyone help me please?

+1 to @ahmadazimi. Rolled back to Laravel v5.3.18, which works.

[ellej16]

Hi @dondencker and @ahmadazimi , As far as I checked jensessegers/laravel-mongodb's source code, it's missing a few key methods/attributes introduced by this particular PR: https://github.com/laravel/framework/pull/15780 . If I remember correctly, one of those are: getSchemaGrammar() and useDefaultSchemaGrammar() on Connection.php (With this being the culprit behind your troubles).

As @dondencker has pointed out rolling back to v5.3.18 works, that could be the easiest route to take, though if you can contact/make a pull request for laravel-mongodb to keep it up to date that'd be lovely.

Cheers!

FatalErrorException in MediaController.php line 23:
Call to a member function store() on null

Showing this issue when i try to store my image to folder.

[ellej16]

Hi @OmarFaruque , I think you should post that somewhere else, this specific thread is for migration files not being rolled back (and the current topic being laravel-mongodb encountering the same issue).
Oh, and do post your code/ snippet of the code being encountered for your issue wherever you plan on taking that issue.

Hope you find the answer to your problem!

Thanks @ellej16 for your replay, my problem Also solved.
