Not working with empty formName() and one column

[olegbaturin]

Here you consider that Model::formName() returns not empty string. As a result input names look like "[attribute][index]" because here you consider that prefix can't be empty.

How to reproduce the issue? In other words, post the code snippet to reproduce the issue

[olegbaturin]

class MyForm extends \yii\base\Model

public function formName()
{
    return '';
}

[olegbaturin]

Use example for single column. Or set the name for only one column the same as the attribute name. See this condition.

Any suggestions on how to fix it? 😄 Throw an exception if form name is empty?

[olegbaturin]

formName() CAN return empty string! It's just a prefix for input name. With prefix name will be "MyForm[email]" (by default), without it - "email".

Any suggestions on how to fix it?

Always return default prefix and check this condition here. So this name will be "'[' . $this->name . '][' . $index . ']'" or "'[' . $index . ']'"
I think.

Do you accept a PRs?

[unclead]

I would rephrase - at the moment I only rely on PR 😄

[unclead]

@olegbaturin so will you make a PR or it was a rhetorical question? 😄

I'll have some time to this fix in the next week or so.
