3,630 PointsGot it!
I had to add the method to the controller
def index
@statuses = Status.all
@status = Status.new
end

If you post your code I should be able to help you. I just need more info on what you are trying to do. :)
Lisa Rossiter
3,630 PointsOk so as an example the below is index.html.erb which prints out my statuses. I want the new status form to be on this page through a partial.
<%= render 'new_status' %>
<% @statuses.each do |status| %>
But I would also like to move the devise sign up form onto my homepage. Would I for the devise new registration form do a route:
root to: "devise/registrations#new"
and code my website homepage into that view. This might be covered later on in the tutorial but I was just wondering.
Michael Williams
8,074 PointsSo if you are trying to make "devise/registrations#new" your root you would just do root 'devise/registrations#new' in 'config.routes.rb'. For the partial you need to put it into a _form.html.erb file in your layouts folder then render 'form' on the root page.
I hope that makes sense :) Let me know if that doesn't answer the question!

3,630 PointsNot quite I get this error if I include a partial in the index.html.erb
undefined method `model_name' for NilClass:Class
Michael Williams
8,074 PointsDid you change your routes.rb file to:
root 'devise/registrations#new'
then create a '_form.html.erb' in layouts folder
and add the form code in the 'form.html.erb'? like
<%= form_for(@example) do |f| %> . . . <% end %>
if you have and that isn't working post the full error message and what you have done.
Lisa Rossiter
3,630 PointsIf we start again. I want to first add the new status form into index.html.erb the page that outputs statuses. Forget about devise for now.
<%= render 'form' %>
<% @statuses.each do |status| %>
My route has only this in it
root to: "statuses#index"
It is outputting the following error.
undefined method `model_name' for NilClass:Class
This comment form doesn't allow me to upload files. Really appreciate your help.
Michael Williams
8,074 PointsHmmm.... It looks like your <%= render 'form' %> is correct. I don't know why it would be throwing an undefined method error. Do you have a git hub account? I could look at your whole code on there.
Michael Williams
8,074 PointsSweet.
Michael Williams
8,074 PointsWait, you didn't put @status = Status.new in your index did you?
Lisa Rossiter
3,630 PointsNo in the status controller?
Thanks for your help Micheal
