Hey all, im not sure where to set a default value if a textfield is empty? For now i do it in the controller, and check if the submitted parameter is blank. But this seems not to be the best solution... Thanks for your help! -- Posted via http://www.ruby-forum.com/.

Do you want a newly created row in the database to have a default value if none is specified? If so, thats where the default value goes. Do you need some sort of default value when processing some sort of logic that the form is the input source for? Then the default value should go somewhere close to where the logic is happening.
I simple want to set a default email address if the user has no one entered. -- Posted via http://www.ruby-forum.com/.

If a user has no e-mail address, just leave the field blank rather than polluting it with bogus data. Or is there something I don''t understand here?

But if the user dont want this behavior he can leave the field blank and we save our no-reply email address... :) -- Posted via http://www.ruby-forum.com/.

Just leave the e-mail field blank in the DB, and use something like @user.email || default_email where you need it in your app. Right now, you are saving bogus data to your DB -- and what happens if your no-reply address changes?

If you want a record of each message exactly as it went out -- including the no-reply address used *at the time*, even if it''s obsolete -- then you should save the default address to the DB. In almost any other case, this behavior is Plain Wrong. (Yes, that''s a technical computer science term. :) ) Best, -- Marnen Laibow-Koser http://www.marnen.org marnen-sbuyVjPbboAdnm+yROfE0A@public.gmane.org -- Posted via http://www.ruby-forum.com/.
It sounds like you want the default value to act sort of like a label, if so here''s a little snippet I''ve used previously that works very nicely. http://codesnippets.joyent.com/posts/show/478 Then format your input like this... <%= form.text_field :email, :value => "fake-Jbz+COfnBihBDgjK7y7TUQ@public.gmane.org" onclick => "clickclear(this, ''fake-Jbz+COfnBihBDgjK7y7TUQ@public.gmane.org'')" onblur => "clickrecall (this,''fake-Jbz+COfnBihBDgjK7y7TUQ@public.gmane.org'''')" %> Just be sure that the 3 values here are all identical.

If it''s important to have the same value in 3 places, then it should be set only once and referred to (in a variable, or with a higher level abstraction). It is *never* OK to have the same literal value in 3 places like this.
