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




restart the server again - rails say that for every gem add restart me pls 

11. With Rails 7 this error is coming now a days after signup -

this error :: 

undefined method `user_url' for Devise SessionsController:create

to resolve this error go to devise.rb and add this below line anywhere in devise .rb :: 

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

after this restart the server and sign up again




12. 

if not found then webpacker also install ::

nvm install v14.10.1

bundle exec rails webpacker:install 

OR

bundle add webpacker

rails webpacker:install




Note :: After this Change in devise.rb of the get action :: definately you should restart the

server then Sign out function will start work and this changes is done after the error of sign

out working not properly
