Added fetchField function to Selection

[foxycode]

I don't understand why fetchField wasn't added to Selection earlier. I am missing it here every day. Hope this will be accepted.

I wanted to create some tests for Selection too, but I can't get existing tests running. Testers show me this: http://i.imgur.com/13EzLhg.png But I am sure that I have pdo installed and enabled.

@foxycode You need to set php.ini http://tester.nette.org/#toc-vlastni-php-ini

What about select($column) before fetch?

[foxycode]

@dg Makes sense, but shouldn't be then select added to fetchPairs too? And it will probably not work for int column key which is default for fetchField function.

[dg]

ActiveRow supports indexed keys?

[foxycode]

As I see, it does not. So I can add select() as you proposed and make $column without default value. Or I can try to update ActiveRow to support indexed keys. What would you like reather?

[dg]

ActiveRow should not support indexed keys. $column default value can be NULL to allow $table->select('xx')->fetchSingle() too.

@JanTvrdik Thanks

[foxycode]

@dg Let me know if this is sufficient. I'll try to write some test then.

[foxycode]

Updated and with test.

[foxycode]

@dg What should I do to push this further?

[dg]

Thanks. Can you change commit message to Selection: added fetchField().

[foxycode]

@dg Changed and rebased from current master

[dg]

Thanks!

[foxycode]

@dg Glad to contribute. Hope you plan new release early :)
