Adding a date to a date attribute in active record












0















I am trying to add a date of birth to each patient in my database and having issues adding a date to the dob attribute on each patient. When I add for ex. Patient.first(dob: "01/25/1990") I get an error reading no implicit conversion of Integer into Hash. Any ideas on how I would do so?



 create_table "patients", force: :cascade do |t|
t.string "first_name"
t.string "last_name"
t.integer "age"
t.date "dob"
t.datetime "created_at", null: false
t.datetime "updated_at", null: false
end


When I seeded my database, my dob field was nil



I have also tried Patient.first(dob: Date.parse('31-12-2010')) and still get the same error.

  • @WaynePhipps I've actually tried that already doing Patient.first(dob: Date.parse('31-12-2010'))

You have two problems:





  1. first doesn't take query arguments.

  2. Your date format is ambiguous.


The first finder method looks like:




first(limit = nil)

Find the first record (or first N records if a parameter is supplied). If no order is defined it will order by primary key.




You want to use find_by as your .where(...).first shortcut.



And to avoid ambiguity with your dates, you should use Date objects or ISO-8601 formatted strings (i.e. YYYY-MM-DD) inside the application and leave the supposedly "human friendly" formats for the very edges.



You want to say:



Patient.find_by(dob: '1990-01-25')
