How do I go to Admin Panel right after installing Rails Admin

[waseem ahmad]

Dear all,

I installed rails_admin in my rails 3.2 application as documented in the Readme. I'm using devise with all the default configurations. When prompted for name of the user model, I gave it admin_user.

I started my server and when I try to go to http://localhost:300/admin, I'm redirected to my application's root_path. This makes a little sense as I have am not signed in as an admin user in my application. And that is because I have not yet created any admin users in my application. My questions are:

1. How do I create an admin user for my application?

And once I have created this user, since going to /admin redirects me to /, I have my second question.

2. How do I sign into admin section of my application using admin user created in first question?

Thanks!

Usually http://0.0.0.0:3000/users/sign_in or http://0.0.0.0:3000/admin_users/sign_in will sign you in, then you shouldn't be redirected anymore.

There is a sign up link there, or you can go to http://0.0.0.0:3000/admin_users/sign_up

Somehow `$ rails g rails_admin:install` did not generate AdminUser model. I tried doing it again and it generated AdminUser model and related migration file. I ran the migration. That also put a `devise_for :admin_users` in my `routes.rb`. So far so good.

Now when I try to go to http://localhost:3000/admin_users/sign_up or /admin_users/sign_in or /admin, I am stuck in an infinite redirection. Following is part of my server logs:

lol

Rails engine router is beeing a little greedy!

It matches '/admin_users/sign_in'

to RailsAdmin Engine :: '_users/sign_in' which you're not authorized to see.

I see 2 solution: use a different URL scope for RailsAdmin, or a different user name.

I will go with the first one. Thanks for all your help.

On a side note perhaps this quirk should be documented in the README. I'm happy to send a pulll request. But not before weekend.

You can edit the wiki, there is a https://github.com/sferik/rails_admin/wiki/Known-issues section, it will only take a minute.

This StackOverflow post helped me solve this bug: http://stackoverflow.com/questions/16448233/no-route-found-even-though-there-is-that-route-specified-in-routes-rb-railsadm

Here is the solution from the post:

rescue_from CanCan::AccessDenied do |exception|
  redirect_to main_app.root_path, :alert => exception.message
end
