Hello, I have a price field that I validate of numbers. How can I default a 0.0 value? Regards, Frank Rocco farocco-PkbjNfxxIARBDgjK7y7TUQ@public.gmane.org
If you set the default in the database, ActiveRecord should automatically use it. On Tue, 6 Dec 2005, Frank Rocco wrote:> Hello, > > I have a price field that I validate of numbers. > How can I default a 0.0 value?
i''m developing a simple content management app in rails where users can
create content in the browser. i''d like to give them the ability to
"tag" content with multiple keywords. so on the form where they are
creating/editing content there is a text field called tag_tags[] where
they can type in space-seperated tags.
i have 3 tables: pages, tags, and pages_tags. i pre-populated tags with
3 records just to test things out.
if a user enters a pre-existing tag in the field, a record gets added to
the pages_tags table appropriately. however, if the user enters a tag
that doesn''t already exist, i''d like to add a record to tags,
and then
add a record to pages_tags with the new tag_id.
here''s my update method in pages_controller.rb
----------------------
def update
@page = Page.find(params[:id])
a = @params[:tag_tags].to_s
ta = a.split('' '')
ta.each{|t|
tg = Tag.find(:all, :conditions => ["tag = ?", t])
@page.tags << tg
}
if @page.update_attributes(params[:page])
flash[:notice] = ''Page was successfully updated.''
redirect_to :action => ''list'', :id => @page,
:section_id =>
@page.section_id
else
render :action => ''edit''
end
end
------------------------
i''ve tried doing a
if tg.nil?
@nt = Tag.create(t)
@nt.save
@page.tags << nt
end
but that doesn''t add a record to the tags table.
any ideas? i am only a few weeks into rails so i am probably missing
something obvious!
thanks!
