Rails - Jul 2006 - Weird issue with editing data.

Hi all.

Ive got a small CRUD app that is giving me some weird isuses.

If I add/create an entry that works fine, the data goes into the db. I
can later show the data, but when I edit it, no data is displayed in the
form for me to edit.

Here is the bits from the controller.

 def new
    @kb=Knowledgebase.new
  end

  def create
    @kb= Knowledgebase.new(params[:kb])
    if @kb.save
      flash[:notice] = ''New knowledge base article created.''
      redirect_to :action => ''index''
    else
      render :action =>''new''
    end
  end

  def list
    @kb_pages, @kb = paginate :knowledgebase, :per_page => 10, :order =>
"created_on DESC"
  end

  def show
    @kb = Knowledgebase.find(params[:id])
  end
  def edit
    @kb = Knowledgebase.find(params[:id])
  end

  def update
    @kb = Knowledgebase.find(params[:id])
    if @kb.update_attributes(params[:kb])
      flash[:notice] = ''Knowledge Base article was successfully
updated.''
      redirect_to :action => ''show'', :id => @kb
    else
      render :action => ''edit''
    end
  end


Here is the edit.rhtml and partial

<%= start_form_tag :action => ''update'', :id => @kb
%>
  <%= render :partial => ''form'' %>
  <%= submit_tag ''Edit'' %>
<%= end_form_tag %>
<br />

<%= error_messages_for ''knowledgebase'' %>
<!--[form:knowledgebase]-->
<p><label for="kb_title">Title</label><br/>
<%= text_field ''kb'',
''title''%></p>
<p><label for="kb_short_description">Short
Description</label><br/>
<%= text_field ''kb'', ''short_description'',
:size => "90"  %></p>
<p><%=text_area ''kb'', ''details'',
:cols=>"90" %></p>
<!--[eoform:knowledgebase]-->

and from the development.log file when I request to edit the entry

Processing KnowledgebaseController#edit (for 192.168.0.134 at 2006-07-27
13:06:05) [GET]

Any insights as to why the data is never grabbed from the db? Ive
confirmed its there, and it does show with a show request.



Many thanks

Jonathan

Hi Jonathan,

I don know what thing brought u this kind of error but one thing I''ve
been
able to see is in the edit.rhtml view (or maybe u hadn''t copy well from
your
code ).

*def edit
   @kb = Knowledgebase.find(params[:id])
end*

@kb = one line from your knowledgebase table...so in edit.rhtml u should do
*:id => @kb.id*

*Here is the edit.rhtml and partial

<%= start_form_tag :action => ''update'', :id => @kb
%>
<%= render :partial => ''form'' %>
<%= submit_tag ''Edit'' %>
<%= end_form_tag %>
<br />
*Hope this works...
