Mysql2::Error: Incorrect date value: '--- !ruby/hash:ActiveSupport::HashWithIndifferentAccess -


i moved sqllite mysql (recreated same workspace mysql right beginning. did not migrations).

the code worked sqllite erroring out mysql. how database.yml looks like:

development:   adapter: mysql2   database: dev   username: root   password:    host: localhost   pool: 5

my code takes in date through date select in view:

<%= date_select(:dob, nil, :use_short_month => true, :start_year => time.now.year - 100,                        :end_year => time.now.year, :order => [:day, :month, :year]) %>

the model looks this:

t.string   "firstname" t.string   "lastname" t.string   "email" t.string   "password" t.date     "dob"

but insert through following code in controller fails:

@user.dob = params[:dob]

this error get:

mysql2::error: incorrect date value: '--- !ruby/hash:activesupport::hashwithindifferentaccess (1i): '2013' (2i): '4' (3i): '18' ' column 'dob' @ row 1: insert `users` (`email`, `created_at`, `dob`, `firstname`, `lastname`, `password`, `personalemail`, `updated_at`) values ('abc@xyz.com', '2013-04-18 15:46:26', '--- !ruby/hash:activesupport::hashwithindifferentaccess\n(1i): \'2013\'\n(2i): \'4\'\n(3i): \'18\'\n', 'abc', 'xyz', 22, null, 'ab4d8d2a5f480a137067da17100271cd176607a1', '2013-04-18 15:46:26')

i had googled quite extent couldnt find references this. appreciate leads or on this.

the problem multiparameter thing. rails date_select helper generates 3 dropdowns pass 3 different parameters controller. if use mass assignment in controller, rails magically converts these 3 values 1 date value. (quite old) blog post shows way without mass-assignment: http://www.springenwerk.com/2008/05/set-date-attribute-from-dateselect.html but, post rather old, , there could(!) better way now

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
