Need to DRY views for a global menu

Rails
1

Hi All,

I’ve got a bunch of views for Vendors and Users, e.g. app\views\vendors
\index.html.erb:

Listing vendors

        <div id="menu">
<%= link_to 'Vendor', :controller=>'vendors',
           :action=>'index'  %>  &nbsp;
<%= link_to 'User', :controller=>'users',
           :action=>'index'  %>  &nbsp;
  </div
  <br/>

<% @vendors.each do |vendor| %>

[snip]

I pasted the div “menu” into all the views. When I change that menu,
I’ve got to change all of them. Pretty bad, eh?

I’ve also got that menu in app\views\layouts\menu.html.erb.

Can I replace the div I pasted in manually with some kind of “include”
referencing that .erb? I tried a bunch of ways to no avail.

Thanks in Advance,
Richard

Nickname Qbname
<%=h vendor.nickname %>

you need to use ‘templates’ but this is rather elemental and suggests
that you need to check out more basic tutorials or possibly AWDWROR
(Agile Web D. With Ruby on Rails)

Hi Craig,

Thanks for your response.

You’re spot on. This is my first “real” Rails app (for my son who
runs a couple of private schools). So I’d like to get this working in
a timely but correctly implement fashion.

Following your link, I modified my working module app\views\vendors
\index.html.erb as follows

h1>Listing vendors

        <div id="menu">
<%= link_to 'Vendor', :controller=>'vendors',
           :action=>'index'  %>  &nbsp;
<%= link_to 'User', :controller=>'users',
           :action=>'index'  %>  &nbsp;
  </div
  <br/>

       <%= render "shared/menu" %>
  <br/>

[snip]

I left in my working menu div and hoping my menu.html.erb or menu.erb
files in app\views\shared will be invoked.

Sadly, I got:
ActionView::MissingTemplate in Vendors#index

Showing app/views/vendors/index.html.erb where line #11 raised:

Missing template shared/_menu.erb in view path app/views

Extracted source (around line #11):

8: </div
9:

10:
11: <%= render “shared/menu” %>
12:
13:


14:

Can you spot where I erred?

Again, thanks in advance for any guidance you may offer.

Best wishes,
Richard

it’s telling you exactly what the problem is…

Missing template shared/_menu.erb in view path app/views
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

OK Craig,

I got it: I missed the _ in the name. Problem solved. Thank you very
much for your help.

Best wishes,
Richard

Thanks again, Craig.

I saw and understood and tried to respond to that message. Following
is the a session in a Command Window on my Win-XP/SP3 system that seem
to provide the alleged missing code:

I know the message said “menu.erb” but I thought it might not be up-to-
date with Rails 2.3.5, which I running, along with Ruby 1.8.6.

If you’re up to another look at this, I’d be in your debt.

Best wishes,
Richard
