Administrate: Cannot run rails generate administrate:install

[nguyen7thai]

Hi All,

I'm trying gem administrate but I encounter the problem when running the command generate administrate:install.

As I investigated, the problem is because of this lines of code in namespace.rb:

def resources
    namespace_controller_paths.uniq.map do |controller|
      controller.gsub(/^#{namespace}\//, "").to_sym
    end
end

Its returned value includes the symbol that is created from empty string :"" .
Does anyone encounter this error?

Here's the backtrace:

I opened this issue 4 days ago. Long story short, it seems to occur when you try to install it but don't have models.

Thank you @coisnepe

[gotjosh]

I just got this one as well! Came here looking for a possible contribution and this guy nailed!

[iammac360]

I already created some models but it still throws an error block in class_name': undefined methodcamelize' for nil:NilClass (NoMethodError)

[iammac360]

I think I got it, I just deleted the

namespace :admin do
root to: "#index"
end

that was generated earlier, after that, it works!

[roadt]

this is another fix i think related. it tries not touch rotues.rb at all. when not valid resources are found. #649

[nickcharlton]

Closing as this should be fixed with #713. Please open an issue if that's not the case!
