ruby on rails - Difference in ways to call partials? -

-
i assuming applies other things well, i've noticed in tutorials i've gone through far. basically, difference between: <%= render :partial => "shared/warning" %> and <%= render partial: "shared/warning" %> the syntax hash literal in ruby is: { key => value } the key can object, including symbol , eg. { :foo => "bar" } using symbol keys in hash became popular, , idiomatic in ruby in ruby 1.9 optional syntax added hash created symbol keys, , there on following precisely equivalent above: { foo: "bar" } update further specific use case, ruby allows drop {} s when passing hash argument method (as being able drop () s), following equivalent: foobar( { foo: "bar" } ) foobar( foo: "bar" ) foobar foo: "bar" foobar :foo => "bar"

sorting - Using linux sort on multiple files -

-
is there way can run following command linux many files @ once? $ sort -nr -k 2 file1 > file2 i assume have many input files, , want create sorted version of each of them. using like for f in file* sort $f > $f.sort done now, has small problem if run again, if not sort files again, create file1.sort.sort go file1.sort. there various ways fix that. can fix second problem creating sorted files thate don't have names beginning "file": for f in file* sort $f > sorted.$f done but that's kind of weird, , wouldn't want files named that. alternatively, use more clever script checks whether file needs sorting, , avoids both problems: for f in file* if expr $f : '.*\.sort' > /dev/null : no need sort elif test -e $f.sort : sorted else sort -nr -k 2 $f > $f.sort fi done

sql - How check if the sum of the values of two columns, in the same row have exactly 100 as result in mysql -

-
i have problem in mysql (phpmyadmin).. should want check if values of 2 columns 100… example have table | blablabla | blablabla | value1 | value2 | and user want add values(bla, bla, 20, 30).. 20 , 30 can't added in table because 20+30<>100.. code is: alter table `partita` check (`100` = (select (`possesso_palla_casa`+`possesso_palla_ospite`) `partita`)) but naturally wrong.. how can do? thank all!!! as commented mysql doesn't support check constraint. per mysql documentation says: the check clause parsed ignored storage engines you should rather use before insert trigger alternative below delimiter // create trigger sumcheck_before_insert before insert on bla_table each row begin if (new.value1 + new.value2 <> 100) signal sqlstate '45000' set message_text = 'can not insert data'; end if end; // delimiter ;
