虽然有很多类似的问题,但我已经搜索了好几个小时但仍无法修复它.

Env rails 3.0.9 ruby​​ 1.9.2 devise 1.4.2

我使用以下命令更改了默认登录网址:

 5   resources :users
 6   devise_for :users, :path => "", :path_names => { :sign_in => 'login', :sign_out  
     => 'logout', :password => 'secret', :confirmation => 'verification', :unlock =>
     'unblock', :registration => 'register', :sign_up => 'cmon_let_me_in' }

$sqr->execute();
while(my @row = $sqr->fetchrow_array()) {
  my $dup_name = $row[0];
  $dup_name = formatHtml($dup_name);
    my $sqr2 = $conn->prepare("select id, unit_id from author where name = '$dup_name'");
    $sqr2->execute();

    my %fir_name_hash = ();
    while(my @row2 = $sqr2->fetchrow_array()) {
        my $author_id = $row2[0];
        my $unit_id = $row2[1];
        my $fir_name = …
