rails: "unknown action" message when action is clearly specified
- by john
hi,
I had hard time to figure out why I've been getting "unknown action" error message when I was do some editing:
Unknown action
No action responded to 11. Actions: bin, create, destroy, edit, index, new, observe_new, show, tag, update, and vote
you can see that Rails did mention each action in the above list - update. And in my form, I did specify action = "update".
I wonder if some friends could kindly help me with the missing links...
here is the code:
edit.rhtml
<h1>Editing tip</h1>
<% form_tag :action => 'update', :id => @tip do %>
<%= render :partial => 'form' %>
<p>
<%= submit_tag_or_cancel 'Save Changes' %>
</p>
<% end %>
_form.rhtml
<%= error_messages_for :tip %>
<p><label>Title<br/>
<%= text_field :tip, :title %></label></p>
<p><label>Categories<br/>
<%= select_tag('categories[]', options_for_select(Category.find(:all).collect {|c| [c.name, c.id] }, @tip.category_ids), :multiple => true ) %></label></p>
<p><label>Abstract:<br/>
<%= text_field_with_auto_complete :tip, :abstract %></label></p>
<p><label>Name: <br/>
<%= text_field :tip, :name %></label></p>
<p><label>Link: <br/>
<%= text_field :tip, :link %></label></p>
<p><label>Content<br/>
<%= text_area :tip, :content, :rows => 5 %></label></p>
<p><label>Tags <span>(space separated)</span><br/>
<%= text_field_tag 'tags', @tip.tag_list, :size => 40 %></label></p>
