Error trying to save DateTime object in DataBase

Hello I am having trouble with datetime objects, I had the "good" idea of making a form, asking for the parameters of DateTime and then give this object to the Database, apparently this is not the way.

I have this error: wrong number of arguments (2 for 1)

And this is what I tried:

I have a model like this       datetime :when       string :where A view like this <% form_tag exams_path do %>   <p>     Place:<br/>     <%= text_field_tag 'place' %>   </p>   <p>   Date and Hour:<br/>   Day: <%= text_field_tag 'day', nil, :size => 4, :maxlength => 2 %><br/>   Month: <%= text_field_tag 'month',nil, :size => 4, :maxlength => 2 %><br/>   year: <%= text_field_tag 'year', nil, :size => 4, :maxlength => 4 %><br/>   Hour: <%= text_field_tag 'hour', nil, :size => 4, :maxlength => 2 %><br/>   Minute: <%=text_field_tag 'minute',nil, :size => 4, :maxlength => 2%><br/>   </p>   <p>     <%= submit_tag 'Save' %>   </p> <% end %> And a controller like this     @fecha = DateTime.new(params[:year].to_i, params[:month].to_i, params[:day].to_i, params[:hour].to_i, params[:minute].to_i)     @exam = Exam.new(DateTime.now, params[:place])     if @exam.save       redirect_to exams_path     else       render :action => 'new'     end

Thanks for your help.

And a controller like this @fecha = DateTime.new(params[:year].to_i, params[:month].to_i, params[:day].to_i, params[:hour].to_i, params[:minute].to_i) @exam = Exam.new(DateTime.now, params[:place])

Assuming Exam is an activerecord object you should be passing a hash of attributes (eg :foo => params[:foo], :bar => params[:bar], whereas you are passing 2 arguments

I didn't understand your solution Fred, thanks a lot for your post. I solved my problem by saving in the database each element of the date as integers, then I read this elements and I build my DateTime element.

I was just saying that you've passed two parameters to Exam.new rather than a hash of options. Fred
