gii/model --tableName=prefix_* generates classnames from the full table name instead of from the matching characters as indicated by --help

[lennartvdd]

What steps will reproduce the problem?

1. Make sure the default db Connection does not have tablePrefix set.
2. Create two or more tables with some prefix, for example: prefix_some_model, prefix_another_model
3. run the command ./yii gii/model --tableName=prefix_*

What's expected?

Two new classes, named: SomeModel and AnotherModel

What do you get instead?

Two new classes, named PrefixSomeModel and PrefixAnotherModel

yii\gii\generators\model\Generator::generateClassName() generates classnames by matching the following patterns:

        $patterns[] = "/^{$db->tablePrefix}(.*?)$/";
        $patterns[] = "/^(.*?){$db->tablePrefix}$/";
        if (strpos($this->tableName, '*') !== false) {
            $pattern = $this->tableName;
            if (($pos = strrpos($pattern, '.')) !== false) {
                $pattern = substr($pattern, $pos + 1);
            }
            $patterns[] = '/^' . str_replace('*', '(\w+)', $pattern) . '$/';
        }

When $db->tablePrefix is empty, this results in an array containing three patterns of which the first two would both be /^(.*?)$/ and the third /^prefix_(\w+)$/. Since patterns are matched in the order in which they appear in the array, the prefix pattern would never match.

Solution would be to check if $db->tablePrefix is empty and not set or change the order of the patterns.

Sounds like clearly a bug. Do you have time for a pull request fixing it?

@samdark i'm think need fix hint or add optional key for switch mode because you cant select more than one model without cutting prefix
