I found a solution.
My fault was, that there where two validations with the same name --> "def validate".
In found in the rails api the solution:
I have only to rename the validation blocks an then trigger the validations with
" validate :block_name"
Here are my new tbl_banks.rb entries:
validate :valid_gueltig_ab validate :valid_gueltig_bis
# Date as textfield with virtual attributes
# date text_field gueltig_ab def gueltig_ab_string if gueltig_ab gueltig_ab.strftime('%d.%m.%Y') end end
def gueltig_ab_string=(gueltig_ab_str) if gueltig_ab_str != '' self.gueltig_ab = Date.strptime(gueltig_ab_str, '%d.%m.%Y') else self.gueltig_ab = gueltig_ab_str end
rescue ArgumentError @gueltig_ab_invalid = true end
def valid_gueltig_ab errors.add(:gueltig_ab, "Datumsformat muss TT.MM.JJJJ sein") if @gueltig_ab_invalid end
# date text_field gueltig_bis def gueltig_bis_string if gueltig_bis gueltig_bis.strftime('%d.%m.%Y') end end
def gueltig_bis_string=(gueltig_bis_str) if gueltig_bis_str != '' self.gueltig_bis = Date.strptime(gueltig_bis_str, '%d.%m.%Y') else self.gueltig_bis = gueltig_bis_str end
rescue ArgumentError @gueltig_bis_invalid = true end
def valid_gueltig_bis errors.add(:gueltig_bis, "Datumsformat muss TT.MM.JJJJ sein") if @gueltig_bis_invalid end
end
