With my observation, I would say you should remove default
value you added to the your foreign fields from (for example):
$table->integer('thnajrn_id', 10)->unsigned();
To:
$table->integer('thnajrn_id')->unsigned();
PS: With a similar experience, I know presently this works with one of the projects I work with in Laravel 5.2.*
Hope this helps :)
When you use $table->integer('thnajrn_id', 10)->unsigned()
; this means your setting the second parameter as true which represents AutoIncrement
try
table->integer('thnajrn_id')->length(10)->unsigned();
When you use $table->unsignedBigInteger('account_id')->nullable();
you can still get this same error, since nullable()
produces a default value can produce that same error. So always leave your foreign key empty, neither nullable
or default(0)
