            </h2>
            <p>There were problems with the following fields:</p>
                <ul>
                <% object.errors.full_messages.each do |message| %>

                <li><%= message %></li>
                <% end %>
                </ul>
            </div>
    <% end %>

This my _micropost_form.html.erb

<%= form_for(@micropost) do |f| %>


<%= render 'shared/error_messages', :object => f.object %>

<div class="field">
    <%= f.text_area  :content %>
    </div>
<div class="=actions">
    <%= f.submit "Submit" %>

    </div>
<%end%>

This is _fields.html.erb

<%= render 'shared/error_messages'%>
<div class="field">
    <%= f.label :name %><br/>
    <%= f.text_field :name%>

</div>


<div class="field">
    <%= f.label :email %><br/>
    <%= f.text_field :email %>

</div>


<div class="field">
    <%= f.label :password %><br/>
    <%= f.password_field :password %>

</div>


<div class="field">
    <%= f.label :password_confirmation, "Confirmation" %><br/>
    <%= f.password_field :password_confirmation %>

</div>

Answer 1

I think you need to go to the file that is calling the _error_messages partial and simply make sure you're calling it using the following:

  <%= render 'shared/error_messages', object: f.object %>

This is because you're adding the hidden field tag.

Answer 2

I had this issue as well, to fix it I didn't adjust the code from Michael's example, I just moved the _fields.html.erb partial from the views/users folder to the views/shared folder. Once in the shared folder it seemed to accept objects from both controllers. Hope this helps.

Answer 3

This is still an issue in the latest version of the book as of this posting.

Earlier in the book the fields for user related forms were refactored and put in a partial _fields.html.erb where the shared/error_messages was rendered.

The users/new and users/edit files don't need to be modified, as stated in the book, and instead the only part that needs to be modified is _fields.html.erb to pass object: f.object to shared/error_messages

Answer 4

Errors 2 through 15 have a simple fix: your _fields.html.erb is missing some code on the first line. The entire line should read:

app/views/layouts/_fields.html.erb   
<%= render 'shared/error_messages', object: f.object %> #object: f.object allows the form variable to 
                #access the associated object.

Unfortunately I can't do anything with the rest of your errors since your relevant code isn't attached.
