Problem with Delete Link?

When I click on the delete link I created, it doesn't do anything (even the flash[:notice] part) in the controller. Am I not calling the .delete? part correctly? The POST part works as I can add tips.

Link:

<%= link_to "Delete", :controller => "/admin", :action => "tips", :id => t.id, :method => :delete, :confirm => "Are you sure?"开发者_JS百科 %>

Admin Controller

def tips
  @tips = Tip.all
  if request.post?
    tip = Tip.new(params[:geek_tips])
    if tip.save
      flash[:notice] = "Saved!"
      redirect_to :action => "tips"
    else
      flash[:notice] = "Error!"
    end
  elsif request.delete?
    tip = Tip.find_by_id(params[:id])
    tip.delete!
    flash[:notice] = "Delete Message"
    redirect_to :action => "tips"
  end
end


Design issues aside, I think that your :method option is being interpreted as a query param. Can you see "method" in the URL if you hover on the link?

If so, try...

<%= link_to "Delete", {:controller => "/admin", :action => "tips", :id => t.id}, :method => :delete, :confirm => "Are you sure?" %>

Note the braces around the part that defines the URL of the request.

Regarding the design: Any time you have multiple actions in one controller method there is probably a design issue. In this case, instead of using one admin controller method to do multiple tips actions I would consider making a dedicated tips_controller controller to map to your Tip model.

If you used RESTful routes, that is, in config.rb you set...

map.resources :tips

...then you could use the create and destroy methods in your tips_controller for creating and deleting your tips respectively.
