Answer 1

to nowy czek w szynach 4. Dlaczego używasz taką starą wersję opracować (i dlaczego jest rc?). wystarczy użyć najnowszej wersji poprzez umieszczenie

gem "devise", "~> 3.0.3" 

w Gemfile

Answer 2

ArgumentError: The provided regular expression is using multiline anchors (^ or $), 
which may present a security risk. Did you mean to use \A and \z, 
or forgot to add the :multiline => true option? 

występuje ten błąd przy próbie aktualizacji z poprzedniej wersji szyny do szyny 4.0.0.

Sprawdzanie Regexp dla validates_format_of. Jeśli nie spodziewasz się danych przychodzących wieloliniowych, musisz zastąpić wszystkie "^" przez "\ A" i wszystkie "$" przez "\ z". Jeśli oczekujesz ciągów wielowierszowych, po prostu podaj opcję multiline: true.

Źródło: http://dev.mensfeld.pl/2013/07/upgrading-to-rails-4-0-from-rails-3-2-test-case-part-ii-assets-models/

Nie wiesz od konkretnego powodu dla błędu, ale chciałbym spróbować opracować aktualizację do najnowszej wersji, która obsługuje szyny 4.0.0.

Answer 3

Używanie^i $ nie jest bezpieczne, ponieważ $ dopasowuje \ n (nowa linia zwinięta), która może wprowadzić wiadomość e-mail, na przykład "test123@example.com \ n < skrypt>/* ... */</script>”

http://edgeguides.rubyonrails.org/active_record_validations.html#format

Więc jeśli używamy^i $, aby dopasować koniec lub początek wyrazu to powyższe może przekazać filtr i złośliwego kodu mogą być przekazywane przy użyciu wiadomości e-mail weszła.

Możemy też użyć/A,/option Z do specfy początek i koniec linii, zamiast^i $, albo możemy ustawić: multilinii opcję prawdziwej

np: sprawdza: zawartość, format: {z:/^ Tymczasem $ /, multiline: true}
