I'm trying to login with the default activeadmin email - admin@example.com and password - password but when i click login i get the error
`wrong number of arguments (2 for 1)`
# POST /resource/sign_in
def create
self.resource = warden.authenticate!(auth_options)
set_flash_message(:notice, :signed_in) if is_flashing_format?
sign_in(resource_name, resource) #ERROR SHOWING AT THIS LINE
yield resource if block_given?
respond_with resource, location: after_sign_in_path_for(resource)
end
May i know what's going wrong ? This is the error i got in my terminal

回答1:
You've said you are using both devise and clearance in your app. Both gems handle authentication, and conflict with each other.
In particular, clearance defines a sign_in method that takes only one parameter:
https://github.com/thoughtbot/clearance/blob/8d3958eb5fdc9b762df4788fd81793801940b754/lib/clearance/authentication.rb#L33
While devise defines one that takes two:
https://github.com/plataformatec/devise/blob/b786c384d54a6365bdc6c0cf6068dc5325a301a9/lib/devise/controllers/sign_in_out.rb#L30
You should either remove clearance or devise from your app, as they perform the same task.

Replace
sign_in(resource_name, resource)
with
sign_in(resource)
