HELP -- I'm missing something

Rails
1

in application controller

@upcomingevents = Event.all

in application layout

<% @upcomingevents.each do |upcomingevent| %>
<%= upcomingevent.name %>
<% end %>

there are events… but i get an error of

ActionView::TemplateError (undefined method `each’ for nil:NilClass)
on line #77 of app/views/layouts/application.html.erb:
74: <%= content_tag :p, msg, :class => key, :id => key -%>
75: <% end -%>
76:
77: <% @upcomingevents.each do |upcomingevent| %>
78: <%= upcomingevent %>
79: <% end %>

It would guess that Event.all returned nil. Did you mean to say
Event.find(:all) ?

In this sort of situation where one cannot see the cause of the
problem by inspection I use ruby-debug to break into the controller
and the view to check the value of variables. This usually gives
useful clues.

I;ve tried both ways of selecting the data… and the log shows select

  • from events… and doing the find in the console works fine.

Drrr make a function… and call it with a before filter…

In recent versions of Rails, those two are equivalent. (Of course, we
don’t know what version the OP is using…)

Well since Event.all should have returned an array and not thrown an
error, my guess is there is a problem with your model/database. Go
into the terminal and open up a session using script/console, at the
prompt enter Event.all and see what it returns…
