undefined method for nil class when rendering partial

I'm trying to run this code and it returns me

undefined method `image' for nil:NilClass

But the syntax and the code seems to be good.

index : 

 - @recipes.each_slice(4) do |recipes|
  .row
    - recipes.each do |recipe|
      .col-md-3
         %h4.modal-title= recipe.title
         .modal-body
            = render :partial =>'show', :locals => {:recipe => @recipe}

_show:

.main_content
  #recipe_top.row
    .col-md-4
      = image_tag @recipe.image.url(:medium), class:"recipe_image"

You have wrong implication in code:

instead of :recipe => @recipe use :recipe => recipe and then in show partial just use recipe instead of @recipe

Or

in index define @recipe = recipe and use @recipe in show.

Try this, Just replace your instance variable @recipe when passing in locale because you already done eaching on it and gets local variable recipe so pass that in your locale and then call like this in your show page.

 recipe.image.url(:medium)

Change your code to:

= render :partial =>'show', :locals => { :recipe => recipe }

Since you don't have a instance variable @recipe, but a local variable recipe defined in the line recipes.each do |recipe|.
