Partials and Models

Hi, I have a partial that needs to output the database data,

In partial:

<% for user in @users %>

 NoMethodError in Users#create_user

Showing users/_user_list.html.erb where line #1 raised:

You have a nil object when you didn''t expect it!
You might have expected an instance of Array.
The error occurred while evaluating nil.each

So does that mean the variable @users from the class User is unavailable
in my partial? If so, how do I bring it into context?

Thanks!

Re: Partials and Models

In your *controller* action, instanciate the @users instance variable,
eg:

@users = User.find(:all)

Alternatively, pass this through when you include the partial, eg:

<%= render :partial => ''some_partial'', :locals =>
{:all_users =>
@users} -%>

..and use
<% for user in all_users %>
in your partial

Re: Partials and Models

Mmmm.. I still seem to be getting the same error message.

This is my controller create_user
  def create_user

    @user = User.new(params[:user])
      if @user.save
        render :update do |rjs|
          rjs.replace_html :userlist, :partial =>
''user_list''
          flash[:notice] = "User was added successfully"
        end
      else
        redirect_to_index("<font
color=''red''>Error</font>")
      end
  end

view:
<div id="userlist">
</div>

partial:
<% for user in @users %>

        <tr class="<%= cycle(''odd-row'',
''even-row'') %>">
          <td class="cell"><%= truncate(user.email, 15)
%></td>
          <td class="cell"><%= truncate(user.password, 10)
%></td>
            <td class="actions">
                <%= link_to ''View'', user %></td>
            <td class="actions">
                <%= link_to ''Edit'', edit_user_path(user)
%> </td>
            <td class="actions">
                <%= link_to ''Remove'', user, :confirm =>
''Are you sure?'',
:method => :delete %></td>
        </tr>

            <div id="<%= user.email %>">
              <tr class="row-details" style="display:
none;">
                <td>sdf</td>
              </tr>
            </div>

<% end %>


Anything stand out as an error?

Thanks!

That''s a very non-standard name. "create" is the usual name
for the
method that does this.

You still haven''t initialized @users. (Did you see Phil''s
response?)
You''re using an uninitialized variable in the view. It can''t
read your
mind :-) If you want it to contain an array of User objects, you have
to assign it the array.
