ruby - Uploading a pdf to rails using paperclip not working -

i using paperclip upload pdf's db. pdf isn't uploaded db, creates blank entry, so:

      2.1.0 :001 > yearlyguide.last          yearlyguide load (1.4ms)  select  "yearly_guides".* "yearly_guides"   order       "yearly_guides"."id" desc limit 1                 => #<yearlyguide id: 2, pdf_file_name: nil, pdf_content_type: nil, pdf_file_size: nil, pdf_updated_at: nil, start: nil, end: nil, created_at: "2014-06-09 14:10:50", updated_at: "2014-06-09 14:10:50">  

my controller looks this:

   def new @yearguide = yearlyguide.new 

end

 def create @yearguide = yearlyguide.create if @yearguide.save   redirect_to '/'  else   render 'new' end 

end

and model this:

   class yearlyguide < activerecord::base has_attached_file :pdf     validates_attachment :pdf, content_type: { content_type: "application/pdf" }     end 

my new.html.erb this:

     <%= bootstrap_form_for(@yearguide, layout: :horizontal, label_col: "col-sm-2", control_col: "col-sm-10") |f| %> 

<%= f.date_select :end %>  <%= f.file_field :pdf, help: "ensure images minimum 400x400px"  %> <%= f.submit "add event", class: "btn btn-primary" %> 

why isn't file being uploaded? missing? there erros code?

rails 3

def create   @yearguide = yearlyguide.new(params[:yearly_guide])   if @yearguide.save     redirect_to '/'    else     render 'new'   end end 

rails 4

def create   @yearguide = yearlyguide.new(yearly_guide_params)   if @yearguide.save     redirect_to '/'    else     render 'new'   end   end  def yearly_guide_params   params.require(:yearly_guide).permit(:pdf) end 

in short you're using .create passing no parameters, because you've got if @yearguide.save want new. if want create sub in create in answer above - leaving params part.
