Hi
I have two date fields in table start_date and end_date .There data
type are datetime. Now in the view I am accepting values of them as
text fields like And I am following RailsCast 32
<%= f.text_field :start_date_string, :value => '''',
:maxlength => 50
%><img src="../images/calendar.png" alt="Calendar"
/>
<%= f.text_field :end_date_string, :value => '''',
:maxlength => 50 %><img
src="../images/calendar.png" alt="Calendar" />
And in my model
validates_presence_of :start_date
def start_date_string
start_date.to_s(:db)
end
def start_date_string=(start_date_str)
self.start_date = Time.parse(start_date_str)
end
def end_date_string
end_date.to_s(:db)
end
def end_date_string=(end_date_str)
self.end_date = Time.parse(end_date_str)
end
But my problem is validates_presence_of :start_date is not working
Even if I dont give any values to start date it does not show any error
message. Please help
Thanks in advance
Tom

Please helpWhen you say it is not working, what exactly is not working? Two things should happen if the validate fails, firstly the record should not get saved to the database and secondly an error message should be made available. You have said that you are seeing no message but is the record getting saved or not? How are you showing the error message? An error here could be the explanation for not seeing the message. Have you tried using ruby-debug to break into your controller and see what is happening when you submit? If you do not know how to do this have a look at the rails guide on debugging at http://guides.rubyonrails.org/.

The OP had an issue with validations, yours is showing an error.

Above it has a newline after :formdate_string, as it shows the %> on line 85. Could that be part of the problem I wonder?

It wasn''t the new line, but that difference was well spotted. I found it... makes sense now... ArgumentError... it wasn''t getting passed an argument for a new form. The form worked for the edit action when the field was populated. I needed to initialize the formdate field with a value. So I added this to the "new" action of the controller. eg. def new @contract = Contract.new @contract.formdate = Time.now.localtime.strftime("%Y-%m-%d") end Would you say this is good practice? or could I do it better elswhere or with different code?
