Question

Just tried writing a simple validates_presence_of in my model, and when the errors try to render, it calls this :

Template is missing

Missing template posts/create with {:locale=>[:en, :en], :handlers=>[:builder, :rjs, :erb, :rhtml, :rxml, :haml], :formats=>[:html]} in view paths "/Users/johnsmith/Sites/shwagr/app/views"

Errors don’t have seperate views in Rails3 do they? I thought that was Rails magic..

Curious if anyone had this problem, or knew how to make it correctly validate.

My Model:

validates_presence_of :category, :name, :url

My Controller:

def new
  @post = Post.new

  respond_to do |format|
    format.html # new.html.erb
    format.xml  { render :xml => @post }
  end
end


def create
  @post = Post.new(params[:post])
  if @post.valid? && current_user.posts << @post
    respond_to do |format|
      if @post.save
        format.html { redirect_to(@post, :notice => 'Post was successfully created.') }
        format.xml  { render :xml => @post, :status => :created, :location => @post }
      else
        format.html { render :action => "new" }
        format.xml  { render :xml => @post.errors, :status => :unprocessable_entity }
      end
    end
  end
end

Update

Interesting, I ‘touch app/views/posts/create.html.haml’, and now it removed the error and instead loads that page instead. But why would it? Or more importantly, how can I make it just redirect back to the new_post_path(@post) like it should?

If your

if @post.valid? && current_user.posts << @post

line returns false, no render() or redirect_to() is called. Rails’ default behavior then is to render the view with the same name as your method. That would be create.BUILDER.FORMAT.

Try to remove the line. Use this code instead:

@post = current_user.posts.new(params[:post])
respond_to do |format|
  if @post.save
    ...

Or write an else case with

render :action => "new"
