Rails 3 validate presence of many columns with custom messages -



Rails 3 validate presence of many columns with custom messages -

is there way specify many validations more concisely?

validates :col_a, :presence => {:message => 'col_a cannot blank'} validates :col_b, :presence => {:message => 'col_b cannot blank'} validates :col_c, :presence => {:message => 'col_c cannot blank'}

i'd settle generic message if had to.

you can give multiple field names validator

validates :col_a, :col_b, :col_c, :presence => true

you can specify multiple validators in same line.

validates :col_a, :col_b, :col_c, :presence => true, :numericality => true

the total error message contain field name. don't need add together field name prefix. if want utilize custom message then:

validates :col_a, :col_b, :col_c, :presence => {:message => "empty value found"}

Accessing MATLAB's unicode strings from C -

Accessing MATLAB's unicode strings from C - how can access underlying unicode info of matlab strings through matlab engine or mex c interfaces? here's example. let's set unicode characters in utf-8 encoded file test.txt, read as fid=fopen('test.txt','r','l','utf-8'); s=fscanf(fid, '%s') in matlab. now if first feature('defaultcharacterset', 'utf-8') , c engevalstring(ep, "s") , output text file utf-8. proves matlab stores unicode internally. if mxarraytostring(enggetvariable(ep, "s")) , unicode2native(s, 'latin-1') give me in matlab: non-latin-1 characters replaced character code 26. need getting access underlying unicode info c string in unicode format (utf-8, utf-16, etc.), , preserving non-latin-1 characters. is possible? my platform os x, matlab r2012b. addendum: documentation explicitly states "[mxarraytostring()] supports multibyte encoded characters...
