Rails 4 nil or empty argument with two forms creating new -


I have two forms to create a new image. I want them to go to both_image_path, but with the @image variable.

gets this error: 
  The first argument in the form is zero or below Can not be   
 one form:  
  & lt;% = form_for @image, url: new_sm_image_path (@image). F | & Gt%;   
 Other:  
  & lt;% = form_for @image, url: new_lrg_image_path (@image) do | F | & Gt%;   
 My route:  
  get "/ sm_image": "image # new_sm", like: "new_sm_image", "/ lrg_image", get For: "images # new_lrg", as such: "new_lrg_image"   
 My index.html.erb has two buttons:  
   & Lt;% = link_to 'lrg_image', id: "new_button"%>    
 
 
 set the example variable  @image  in your controller's action Are rendering these forms are currently  @image  is zero, therefore you get an error because the first argument in the form  can not be included in the vacuum or may be empty .  
 According to the comment,  
  I have two buttons in my index.html.erb which link_   for the routes I've found 
 You are implementing your ideas in the form of the   new_sm  and  new_lrg  in two functions:  @image .
