rails partial passing param got empty variable

Question

I try to pass a param to a partial in view

controller

def addMovie
  @movies = Movie.all
  @vid = Movie.new
end

view

<%= render partial: "shared/videoList", videoList: :movies %>

partial stored in app/views/sharead

<% if @videoList.present? %>
    <% @videoList.each do |movie| %>

videoList is empty ... why?

try render 'shared/videoList', :locals => { videoList: @movies} — chaitanya

problem is that '@movies' is empty. ... I tried <%= Movie.all.inspect %> in view ... works fine ... but the @movies is empty ... — Felix

Access the variable using videoList and not @videoList,

<% if videoList.present? %>
    <% videoList.each do |movie| %>

also, you need to pass the variable like this

<%= render 'shared/videoList', videoList: @movies %>

Hope that helps!

thanks. but then I got this error: 'undefined local variable or method `videoList' for'

but in database there are entries

Check if the @movies variable is empty or not!
