Rails - how to create sample record in rails?

Question

I tried these (tried in model file and in controller file):

record1 = Model.new("something", "something2", "something3")
record1.save

Nothing happened.

Tried to create record in seeds.rb file:

Model.create!(name => "something")

Then I get error:

wrong number of arguments (3 for 0..1)

But my table has three columns...

Then I tried to roll back migration and enter inside migration file like this:

record1 = Model.new(name: "somethingk", name2: "something2", name3: "something3")
record1.save

It migrated, but still schema did not create any records. So what is the way to create sample records in rails? I'm using rails 4.

Answer 1

The right way is using the seeds (db/seeds.rb):

Model.create!({:name1 => "something", :name2 => "something"})

The argument must be an hash (which is a single argument), probably you wrote something different for mistake
