问题 FindOrCreate is suppose to either find or create based on the arguments you give it.

问题 I have some jquery in my view file where I want to take all of the values of the individual fields with the name, discoverySource . The solution thanks to some help from a stack user was to use the lodash module and then map the array into individual values to be appropriately used for my sequelize BulkCreate function.
