问题 I'm using rails_admin in an app and I'm getting an unexpected error. In a certain model, I have a field called *_status_id. When trying to edit that model in rails_admin, I get this error: undefined method `*_statu_id' Obviously, rails_admin thinks my resource is plural, when it is not. Is there a way of letting Rails/rails_admin know how to use this resource properly? 回答1: "status" has an irregular plural; one which Rails doesn't know about automatically. In config/initializers/infelctions

问题 How do you implement authentication with the rails_admin gem when you are not using devise e.g. you have rolled your own authentication? 回答1: In config/initializers/rails_admin.rb include a config.authenticate_with block and place your authentication logic there. It should raise an exception if the user is not authorised to use rails_admin. Here is a simple example: RailsAdmin.config do |config| config.authenticate_with do raise 'You must be admin' unless signed_in? && current_user.admin? end

问题 When a user in my app isn't an admin user i want to only let them see the fields that they have ownership of. Is there a so set can :see or something like that on a per field basis so that it displays just the fields that that use "can see", or should I have an ability called can :oversee to state that they can see everything instead. I suppose it's much easier to just check if the user is admin or not in rails admin, so where set rails admin to only pull the current user's records. 回答1: With

问题 When I go to a paper_trail history page in rails_admin, I see User objects in the User column ( #<User:0x007f59a9... ). Is there a way to configure this to use one of the User attributes? I thought I could use object_label_method but I don't seem to be having any luck. Update: I thought this was purely a display issue but paper_trail is actually storing Strings like #<User:0x007f59a9... in the whodunnit column of the versions table rather than IDs. I have overridden user_for_paper_trail in

问题 I am developing an app in Rails 3, currently I use Devise as the login and Rails_admin as the admin panel with Paper_trail tracking all changes made by 'user' model... Problem is I have two user models, User and Admin. So a line of code in rails_admin.rb (initiliazer) to setup Paper_trail to track history: config.audit_with :paper_trail, User Is there any way to have paper_trail monitor changes made by both User and Admin, or can it only follow one model? I notice that even when it is set

问题 I am trying to filter the the data to be exported in the csv file that rails admin will generate but I want to only export data for a particular email so that no other users can export another person's data. Is there a way to do this? 回答1: You will have to implement your own export action to do this. I won't be that hard since you can just copy paste the existing one found in https://github.com/sferik/rails_admin/blob/master/lib/rails_admin/config/actions/export.rb In your own project root
