Can't Save a new object even though the request parameters are correct

What is the datatype that you have set for the date_of_birth column? If it’s date-time, then you can try convert the string into Date object first and then store the parsed value in database.

My form fails with the error Mysql2::Error: Column 'date_of_birth' cannot be null. However the Request Parameters have a value for date_of_birth, so i'm not sure whats going on. Request:

{"utf8"=>"✓", "authenticity_token"=>"3njnNBX4VgoV32kau3OALfhdIP00Bq78we6EKD7OXHo=", "pilgrim"=>{"surname"=>"Lorem", "first"=>"Ipsum", "middle"=>"Lorem", "aka"=>"Lorem", "title"=>"Mrs. ", "address"=>"111 Mockingbird Lane", "city"=>"City", "state"=>"CA", "email"=>"loremipsum@gmail.com", "telephone"=>"889-279-2727", "nationality"=>"USA", "passport_number"=>"123455", "expiration"=>"06-15-2015", "date_of_birth"=>"06-15-1086", "jordan"=>"yes", "room"=>"Share", "leader"=>"Group Leader", "price"=>"4000", "deposit"=>"500", "trip_id"=>"44", "balance"=>"3500"},

"commit"=>"Save"}

Here's a gist with the form and controller code that's causing the issue. https://gist.github.com/4429457

Is this valid?

"date_of_birth"=>"06-15-1086",

??

It was what i put in. It’s probably not entirely valid, but i haven’t put that type of validation into the form yet.

What shows up in your log?

I'm just curious how it works, and how your model is set up. Entering a date value of "06-15-1086" into mysql gives a 0 date. Assuming that's MM-DD-YYYY, mysql needs YYYY-MM-DD unless you do some other munging. (Plus, I'm curious about a birth year 1000 years ago...)

If i was going to put the date into the correct format, would i do it within the controller or the model?

If you consider that a valid form of date (which it is), then doing the manipulation to make it work in the model should go in the model, notably using a before_save hook.

OTOH, if you accept any sort of string in that field, you will probably need to validate it's contents before passing it off to the model, and that should go in the controller.

OTOOH, put it where it makes the most sense to you.

ok. thanks.
