Hi there, I’m a compete Rails n00b and trying to understand how this thing works so any help is greatly appreciated. I created a table using migrations, so far so good. My view shows the list and I can add new records. Now I forgot one column so I added it by creation a new migration file with an add\_column. Raked this migration and checked the database, it’s there. When I go to my listing web-page the listing is updated BUT, when I click the New link on this page the input forms still show the old structure and my newly added column doesn’t show up. I tried to do this without migrations (manually in the database), restarted Apache, restarted MySQL, migrated to version 0 and back and it still doesn’t show up. What am I missing here? Many thanks! ---

Could show your view code, and your controller code? Stephan ---

Well those scaffold just get you started. They are not really designed to continually reflect on your database structure. After you generate them you are expected to maintain them yourself. This is not a limitation, it’s designed to make you move past that featureless ugly scaffold and into wherever you want to go. So to add that new field to your forms, you need to add the view code for it. As you can see in your new.rhtml file, it render the partial called “form”. Look in that same folder for a file named “\_form.rhtml” because that is what is being rendered. Copy one of the existing form field declarations and change the field name its accessing. ---

Yes! Thanks, have been looking for this for days and never got to the \_form.rhtml. Doh! I can see it new, off course you don’t need the duplicate code in the edit.rhtml and new.rhtml so this makes sense. Thanks Alex, this hold me back from going on, thanks to you I found the motivation again. ---

Sure I can. This is the blog\_admin\_controller which I didn’t change: * * * class BlogAdminController \< ApplicationController def index list render :action =\> ‘list’ end # GETs should be safe (see [URIs, Addressability, and the use of HTTP GET and POST](http://www.w3.org/2001/tag/doc/whenToUseGet.html)) verify :method =\> :post, :only =\> [:destroy, :create, :update], :redirect\_to =\> { :action =\> :list } def list @blogpost\_pages, @blogposts = paginate :blogposts, :per\_page =\> 10 end def show @blogpost = Blogpost.find(params[:id]) end def new @blogpost = Blogpost.new end def create @blogpost = Blogpost.new(params[:blogpost]) if @blogpost.save flash[:notice] = ‘Blogpost was successfully created.’ redirect\_to :action =\> ‘list’ else render :action =\> ‘new’ end end def edit @blogpost = Blogpost.find(params[:id]) end def update @blogpost = Blogpost.find(params[:id]) if @blogpost.update\_attributes(params[:blogpost]) flash[:notice] = ‘Blogpost was successfully updated.’ redirect\_to :action =\> ‘show’, :id =\> @blogpost else render :action =\> ‘edit’ end end ## def destroy Blogpost.find(params[:id]).destroy redirect\_to :action =\> ‘list’ end end And my view code, I suppose you mean the new.rhtml as this is the page that isn’t updated. The edit function also shows the outdated table structure. * * * # New blogpost \<% form\_tag :action =\> ‘create’ do %\> \<%= render :partial =\> ‘form’ %\> \<%= submit\_tag “Create” %\> \<% end %\> ## \<%= link\_to ‘Back’, :action =\> ‘list’ %\> Many thanks!
