Thanks colin,
what i am trying to do,
*branches_controller*
*
*
class BranchesController < ApplicationController
def branch
@branch = Branch.new
end
def create
@branch = Branch.new(params[:branch])
@name = "vishnu"
end
end
*branch.html.erb*
<h4> new <%=@name %> </h4>
<%= form_for(@branch) do |f| %>
<%= f.submit "Save" %>
<%end%>
if i have to get @name in branch.html.erb, i have to define that branch
action in BranchesController, am i correct...?. So in this application all
the main function done in create action in BranchesController. In that way
how to get that values in branch.html.erb
