Rails - Jul 2006 - Still struggling with data flow ...

Hello,

The following view:

    <%= start_form_tag %>
      Enter term to find
      <p>
        <%= text_field_tag :name, params[:name] %>
      </p>
        <%= link_to "Find",  { :action =>
''find_term''} %>
    <%= end_form_tag %>

does not appear to pass back the value of :name to the action:

  def find_term
      term = Term.find_by_name(params[:name])
      if term
        redirect_to :controller => "term", :action =>
"show", :id =>
term.id
      else
        flash[:notice] = "Unable to find the term: #{term}"
      end
  end

The notice printed is:

     Unable to find the term:

How do I pass back the value of the inputted variable to the controller? 
''elp!

The problem you have is you are putting a link in to form, expecting that to
post the form. Try this...

replace your start_form_tag with <%= start_form_tag :action =>
''find_term''
%>
and then repalce your link_to call with <%= submit_tag
''Find'' %>
