我担心这里的解决方案会非常明显，但是我在执行 Devise wiki 上的说明时遇到了麻烦（https://github.com/plataformatec/devise/wiki/How-To%3a-Allow-users-to-编辑他们的帐户而不提供密码）
我正在使用 Rails 4。在关注 wiki 之后，我仍然收到“当前密码不能为空”。这是我的设置。非常感谢任何帮助！
REGISTRATIONS_CONTOLLER.rb
class RegistrationsController < Devise::RegistrationsController
def update
@user = User.find(current_user.id)
successfully_updated = if needs_password?(@user, params)
@user.update_with_password(devise_parameter_sanitizer.for(:account_update))
# Rails 3: @user.update_with_password(params[:user])
else
# remove the virtual current_password attribute update_without_password
# doesn't know how to ignore it
params[:user].delete(:current_password)
@user.update_with_password(devise_parameter_sanitizer.for(:account_update))
# Rails 3: @user.update_without_password(params[:user])
end
if successfully_updated
set_flash_message :notice, :updated
# Sign in the user bypassing validation in case his password changed
sign_in @user, :bypass => true
redirect_to after_update_path_for(@user)
else
render "edit"
end
end
private
# check if we need password to update user data
# ie if password or email was changed
# extend this as needed
def needs_password?(user, params)
user.email != params[:user][:email] ||
params[:user][:password].present?
end
