Rendering Error with Devise and Mobylette

问题

I am using Mobylette with Devise on my Rails 4 app.

When I try to sign up, sign in, or reset my password on my mobile device I get this error:

ActionController::MissingRenderer (No renderer defined for format: mobile)

Has anyone else had this issue?

I've tried setting up a fallback chain

mobylette_config do |config|
  config[:fallback_chains] = {
    mobile: [:mobile, :html]
  }
end

and adding this to the devise initializer

config.navigational_formats = ['*/*', :html, :mobile]

But continue to get the renderer error.

Any recommendations would be awesome, still new to mobile formatting.

回答1:

Please modify

config/initializers/devise.rb

config.navigational_formats = [:"*/*", "*/*", :html, :mobile]

回答2:

Solved the issue with the following..

created an initializer and added this:

ActionController::Responder.class_eval do
  alias :to_mobile :to_html
end

along with Preshant4020's suggestion

config.navigational_formats = [:"*/*", "*/*", :html, :mobile]

in the devise initialize and got it to work with no issues.
