I'm studing a forum and when I create a Topic I have a _form.html.erb relative a file inside follow directory

#app/views

new.html.erb _form.html.erb .... ....

the snippet controller to create a new topic is the follow

#app/controllers/topics_controller.rb

def create     @topic = Topic.new(params[:topic])     if @topic.save       @topic = Topic.new(:name => params[:topic][:name], :forum_id => params[:topic][:forum_id])

        if @post.save         flash[:notice] = "Successfully created topic."         redirect_to "/forums/#{@topic.forum_id}"         else         render :action => 'new'         end     else      render :action => 'new'     end   end

No need create only 2 simple line in the follow file

#app/controllers/topics_controllers

def new

@topic = Topic.new @post = Post.new

end

def create def create     @topic = Topic.new(params[:topic])     if @topic.save       @topic = Topic.new(:name => params[:topic][:name], :forum_id => params[:topic][:forum_id])       @post = Post.new(:content => params[:post][:content], :topic_id => Topic.first.id)         if @post.save         flash[:notice] = "Successfully created topic."         redirect_to "/forums/#{@topic.forum_id}"         else         render :action => 'new'         end     else      render :action => 'new'     end   end
