ActiveAdmin: how to leave user password unchanged?
Devise provides an update_without_password
method that you can use when updating a user if no password is entered. Using that method, you can customize the update method in your ActiveAdmin users controller.
def update
@user = User.find(params[:id])
if params[:user][:password].blank?
@user.update_without_password(params[:user])
else
@user.update_attributes(params[:user])
end
if @user.errors.blank?
redirect_to admin_users_path, :notice => "User updated successfully."
else
render :edit
end
end
The Devise Wiki has more information about this method if your interested.
You don't really need to mess at all with Devise's registration controller, you can just ignore empty password fields inside ActiveAdmin's resource controller:
ActiveAdmin.register User do
controller do
def update
model = :user
if params[model][:password].blank?
%w(password password_confirmation).each { |p| params[model].delete(p) }
end
super
end
end
end
You need to evaluate password and password_confirmation in the if statement, to apply the validations on "password_confirmation", eg for my case:
#app/admin/user.rb
controller do
def update
if params[:user][:password].blank? && params[:user][:password_confirmation].blank?
params[:user].delete("password")
params[:user].delete("password_confirmation")
end
super
end
end
#app/model/user.rb
validates :name, :email, presence: true
validates :password, :password_confirmation, presence: true, on: :create
validates :password, confirmation: true
This allows me to validate password presence only when I create a new user and update without changing his password.
This work for me, I hope this is helpful.
