rails partial passing variable does not work

Question

I have this: view:

confirmations.each do |c|
  <%= render "form", confirmation: c %>
end

partial:

<%= simple_form_for @confirmation do |f| %>
    ...

Rails for some reason gives me this error:

NoMethodError in Rosters#show

undefined method `model_name' for nil:NilClass

highlighting the line in the above partial.

NoMethodError in Rosters#show

undefined method `model_name' for nil:NilClass

It should be <%= simple_form_for confirmation do |f| %> not <%= simple_form_for @confirmation do |f| %> as your variable is confirmation not @confirmation

In other files I have <%= render "form", confirmation: @c %> and it works

@DrevanTonder It all depends on existence or access of @confirmation. Does the error resolved?

@DrevanTonder Then you should accept my answer and BTW read more about local variables and instance variables in Ruby.
