Administrate: uninitialized constant Administrate::Generators::InstallGenerator::DashboardManifest

Hi :smiley:

When I run the installer for Administrate, I get the following error:

Is anyone else getting this error? I get this error even on a totally new Rails application, so it should be pretty easy to reproduce.

I was also getting this error. i deleted the lines it added in my routes then ran spring stop and the generator again and this time it worked.

But after installing for 10 times now its working, the reason? i don't know u.u

Hi, I'm having the same problem. Did you figure this out?
When I do: rails generate administrate:install

I get this error:
`block (2 levels) in

Reading some of the blogs about this, it seems that it might be related to spring gem or HABTM relationships which are defined incorrectly. I'm not sure if there is a suggested solution. Have you figured out how to fix this?

Thanks

Well when you "rails generate administrate:install" the routes appear in the config/routes.rb file, and those line generate the error. So, i "rails generate administrate:install" and then removed that lines from config/routes.rb file like 10 times, maybe is what you are saying (the spring gem) or something more complicated.

Xosmond on 23 Jan 2016

But don't you need the routes for the gem to work? It put these lines in my routes file:

namespace :admin do
DashboardManifest::DASHBOARDS.each do |dashboard_resource|
resources dashboard_resource
end

root controller: DashboardManifest::ROOT_DASHBOARD, action: :index

end

Are you saying the solution is to delete all of this?

MincePie on 23 Jan 2016

Im saying that you should delete them and try to install administrate again(when you install it again the routes will appear again on the routes file), then test if it works. I did many times.

I was also getting this error. i deleted the lines it added in my routes then ran spring stop and the generator again and this time it worked.

thanks Quintin - that worked for me too

MincePie on 23 Jan 2016

Yes that makes sense, spring always causing problems

Xosmond on 23 Jan 2016

DISABLE_SPRING=1 rails generate administrate:install works. thanks.

Works for me too! Thanks :smiley:

frabrunelle on 24 Jan 2016

Worked for me too. Thank you.

I ran into this issue as well. Turns out I had my rails server running when I tried to run the install command. Removed the routes, shutdown the server, and ran it again without issue.
