Calling new on the db string name
Ok so i have the string "Product".
table_name = "Product"
I cant do
table_name.new
undefined method `new
So i was trying to f开发者_运维问答ind a work around like this
table_name = table_name.downcase.pluralize
name = ActiveRecord::Base.connection.tables.select { |t| t == table_name }.first
name.new
I am not sure this will work but even if it does it looks like a hack, any ideas to clean this up
If you want to avoid calling eval
you can also do
"product".camelize.constantize.new
try this:
(instance_eval table_name).new
