How to create multiple records from array in Rails Console

Question

I want to create 7 categories in production, so I have an array for them:

categories = ["Industrial & Loft","Nórdico","Moderno","Clásico","Contemporaneo","Exótico","Rustico","Landing"]

I want to loop through the array in rails console, and create a new category for each of the items, but this wont work:

categories.each { |category| category.new}

It says: NoMethodError: undefined method `new' for "Industrial & Loft":String

What am I missing? Thanks

you can call .new method only on class and class should start with capital `Category — Rahul Dess

If Category is one of your model classes, then you need to capitalize it and then assign the value of the categories item to one of the model elements (such as name in my example):

categories.each { |c| Category.new(name: c)}

Edit: But remember that "new" doesn't save a record, so you might want to use create, which is new & save combined:

categories.each { |c| Category.create(name: c)}
