Migration?

Hello, I am fairly new to rails, and I keep having an error in my migrations, cant mass assign protected attributes… it does not show what attribute is mass assigned, just shows the file that has the problem… here is the file any help would be greatly appreciated!!

class Subjects < ActiveRecord::Migration

def self.up

create_table :subjects do |t|

t.column :name, :string

end

Subject.create :name => “Physics”

Subject.create :name => “Mathematics”

Subject.create :name => “Chemistry”

Subject.create :name => “Psychology”

Subject.create :name => “Geography”

end

def self.down

drop_table :subjects

end

end

Thanks!

try add Project.reset_column_information before Subject.create

try add `Project.reset_column_information` before Subject.create

Or even Subject.reset_column_information

Don't use migrations to set data, use seeds for that if you must. Using
migrations can lead to inabilities to rollback if need be.

The exceptions to this are cases where model relationships or default
values need to be set to have the application work. Your example is not
such a case.
