Answer 1

Description is not an attribute of Job model/table and still you are using it in your form_for that's why it's giving undefined method description.

Answer 2

You haven't got a description on your job model. Run this command in your console:

rails g migration add_description_to_jobs description

'add_description_to_jobs' creates the migration file itself, and 'description' will create a string field 'description'. If you said 'description:integer' it would instead create it as an integer, but you won't need that in this instance.

Answer 3

What I can see is you are using simple simple_form_for with @job, and in the code you have

f.input :description, label: "Job Description"

So this error means your @job object is not having "description" attribute, which you have used with f.input, please check for that.
