Is there a way to use Rails model for validation only without interaction with the database?
Would I generate model using console and use it with Active Record validations?
I'm trying to use it to validate a CSV import, use Model validations, process then output back in another CSV format.
This is done without database interaction but I thought for validation, using Model would be a good way to be less error prone.
Look into ActiveModel
E.g. specifically for validations (taken from the above docs)
class Person
include ActiveModel::Validations
attr_accessor :first_name, :last_name
validates_each :first_name, :last_name do |record, attr, value|
record.errors.add attr, 'starts with z.' if value.to_s[0] == ?z
end
end
person = Person.new
person.first_name = 'zoolander'
person.valid? # => false
Yes you can do this, Lets suppose you have a Person class, than you can do this:
class Person
attr_accessor :name, :age
include ActiveRecord::Validations
include ActiveModel::Validations
validates_presence_of :name
end
