Framework: DEFAULT value in table migration cannot be executed if it is a function

[digirew]

When i specify a function name as a table column default, this is wrapped into quotes so when executed the function isn't run, its saved as a string.

This gives an error fortunately because UUID col can't have a default string value of this type.

Schema::create('products', function(Blueprint $table)
        {
            $table->uuid('id')->default('gen_random_uuid()')->primary('products_pkey');
            $table->string('name')->nullable();
            $table->string('max_projects')->nullable();
            $table->timestamps();
            $table->softDeletes();
        });

Try with DB::raw:

 $table->uuid('id')->default(DB::raw('gen_random_uuid()'))->primary('products_pkey');

You can't use a function as a default value in MySQL. It has to be a constant. To generate a UUID, you'd have to either use a trigger or do it manually.

gen_random_uuid() is a Postgre function.
