rails-admin

问题 I needed this myself, so here it is QA-style: By default, Rails Admin shows a model's default_scope. How do I get it to show every model completely unscoped? 回答1: Approach 1 If you only need to list the records you can use the scopes method to control which records are returned. The first array element is the default, so if you add the following to your initialiser: list do scopes [:unscoped] end you will see all records. Approach 2 If you want to do more than list models you can create a

问题 Using rails_admin for a very basic Rails 4 application. However, whenever I open up the dashboard (mounted at '/admin'), I do not see the edit, show, or delete link buttons for each of my records. Interestingly, if I manually go to the show or edit routes (i.e. /admin/ products /1 or /admin/ products /1/edit) the page shows up just fine and works as expected. Is there a configuration to turn these links on? Thanks for your help. 回答1: I figured it out! It turned out to be a conflict with

问题 I'm trying to install the Rails Admin Gem using Sorcery for authentication instead of Devise. Rails admin does provide a hook that you can use to attach your own authentication method. Here is the example they provide in their docs (using warden): config.authenticate_with do warden.authenticate! :scope => :admin end config.current_user_method { current_admin } I'm guessing that inside the block I need to reference the before_filter that Sorcery uses to authenticate users, which would be

问题 My app is Rails 4.1 with rails_admin 0.8.1. I want to create custom action that only shows articles that belong to logged in user. If I were using regular Rails scaffolding I would just create a new action in articles controller and tell it to use index view. I registered the action properly in rails_admin.rb so it shows up.
