I generated controller and view as.
"script/generate controller home index"
Tried to make a form .Edited the index method in home controller and
added follwoing stuff inside
<%= form_for @home do |f| %>
<%= f.label :first_name %>:
<%= f.text_field :first_name %><br />
<%= f.label :last_name %>:
<%= f.text_field :last_name %><br />
<%= f.submit %>
<% end %>
Then started the server But it didnt generate form.Am i missing
anything(i hope so).Should anything be added in index.html.erb file in
home view?Or else?Using rails 3.0.7.I Have read the form generation
tutorils but could not understand lot.So asking here.

Amrit Pal Pathak

In the browser do View > Page Source or similar (dependant on browser). Colin -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Is that correct? Did you really work right through it, examining the code generated by the scaffolding, making sure you understood everything there, and experimenting with small changes to make sure you understand what is going on? If so then I cannot understand how you do not know that code that generates a form for display in the browser must go in one of the view files. *Please* work through the getting started guide again and make sure you understand it. That way will save us all a lot of time. Once you have worked through that guide then find a more complex one (I think I recommended the free-to-use-online one at railstutorial.org previously) and work through that.
