can't convert Symbol into String
It seems like you are trying to use strong paramaters. You get this error cannot convert symbol into string because you have not configured the strong_parameters. So by default you cant use require on params with symbols.
Configure strong parameters as follows:
1.) Add gem 'strong_parameters' to your gemfile and bundle it.2.) Include Restrictions to you model as follows. include ActiveModel::ForbiddenAttributesProtection to your model.3.) Disable white listing in application confiuration(config/application.rb) config.active_record.whitelist_attributes = falseSee the documentation for more details on configuring.
Now your code should work.
If anyone is using Mongoid, you can fix this issue by adding the following to an initializer:
Mongoid::Document.send(:include, ActiveModel::ForbiddenAttributesProtection)
Add gem 'strong_parameters' to the gem file and run >bundle install in command promptRefresh the browser.
