Hello,
The gist of this is that I'm trying to move an item from one partial to another, and the item disappear when I delete it from the first partial, and have that item appear in the second partial instantly. Just moving a listing from one partial to another, without rerendering the entire page. Simple, right? Can't figure it out.
I have two partials (lists) on a page (index).
Each partial gets drawn, paginated, from this part of my index controller:
def index
@listing_pages, @listings = paginate(:listings, :conditions => ["search_term_id = ? and deleted = '0'", id], :order => 'position', :per_page => 50) @deleted_listing_pages, @deleted_listings = paginate(:listings, :conditions => ["search_term_id = ? and deleted = '1'", id], :order => 'updated_at DESC', :per_page => 5)
end
Both partials work, and paginate correctly. I've put the code for them below.
When I click a button, I want a listing's "deleted" column in the database to update from 0 to 1, then update the _deleted_listings.rhtml partial, so that the "deleted" listings shows up in the "deleted_listings.rhtml" partial.
I have an action in my controller called "update_deleted" that does just this, and it works in the database. I have a partial called update_deleted.rjs that looks like this:
page.replace_html "deleted_web_listing", :partial => "deleted_listings"
And it does not work. Help! I can't figure it out. When I do this:
page.replace_html "deleted_listing", '<div>replacement text</div>'
I see "replacement text" in the right place. But when I put the partial name in there, I get an error that suggests that my partial _deleted_listings.rhtml is not picking up the right parameters to render properly, though it renders fine when called from the page index.rhtml.:
ActionView::TemplateError (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) on line #2 of app/views/ admin/_deleted_listings.rhtml: 1: <div id="deleted_web_listing" class="left_column_listing"> 2: <% for listing in @deleted_listings %> 3: <div id="deleted_item_<%=listing.id %>" class="box_left"> 4: <div class="x_image"> 5: <%= link_to_remote(image_tag("restore.gif", :size => "44x13", :border => "0" ),
