How to run existing ruby on rails project in linux - ruby-on-rails

Question

I have an existing ruby on rails project on my desktop (Moovit). now i want to run this existing project on my linux. but i can't seem to run it. i dont know if im doing it right. i transferred it to my root folder then i run this code rails new Moovit -s i dont know if this is correct? It's not working and when i checked on my browser. it says hello world . the Moovit project is a website. I've created a backup in case of trouble. I also go to Moovit folder then rails s but it's not working. I also run bundle install but still not working. How should I do it?

Your bundle is complete! Use `bundle show [gemname]` to see where a bundled gem is installed.
cd Moovit
rails -s

also how should i run it on my specific ip address? it seems that on my /var/www/html/ there's an index.html which says hello world. and my ruby on rails project is on root folder. I'm really lost. I thought when just running those commands will make it available to my server?

Answer 1

Go to /config/initializers/wrap_parameters.rb, comment out the previous codes and try this code
ActiveSupport.on_load(:action_controller) do
include ActionController::ParamsWrapper
wrap_parameters format: [:json] if respond_to?(:wrap_parameters)
end

Answer 2

Follow Bellow Instruction:
cd project_name
bundle install
rails s
Also which version of rails do you use for project.
Please add config/initializers/wrap_parameters.rb and the restart your server.
ActiveSupport.on_load(:action_controller) do
if self == ActionController::Base
wrap_parameters :format => [:json]
end
end
