Help! I am so close.
Here’s the thing, I am committed to ding it this way for a number of
reasons. I have inherited a codebase that was done pretty well, and I
can’t really be reinventing the wheel over and over.
What we have here is a relatively simple image upload partial, that is
attached to a separate edit form. The whole thing works fine, except
for a strange javascript error that I only see in Firebug. It says
this:
GET http://localhost:3000/highlights/73/highlight_images/new
(754ms)prototype.js (line 1223)
loc is not defined
[Break on this error] Action Controller: Exception caught</
title>
create_image (line 3)
ok stay with me here - I configured the highlight_image as a sub-
resource of highlights. I found out that uploads cannot happen
remotely, so that is why this is one of the only straight upload
utilities in the entire app. When I leave out the ‘responds to parent’
call at the bottom of the controller method, everything is fine but I
end up with a modal overlay and a spinning upload widget (ie,
create_image.rjs does not run). The upload does run correctly,
however.
now, if i put the responds to parent call back in, the rjs runs, the
modal overlay goes away, the html gets replaced correctly but then I
have the above error. It is as if, after rendering the create_image
method it has to keep going and render something else, so the render
to parent calls the create_image.rjs correctly but keeps going like a
runaway train.
Any ideas? Is there something I can put at the bottom of my
create_image.rjs to keep it from continuing after it renders itself
correctly?
thanks!
code below:
Here is the whole controller create method,
highlight_images_controller.create_image:
def create_image
@facebook_id = params[:facebook_id]
if params[:highlight_image][:uploaded_data].blank?
success = true
@blank_data = true
#@highlight = Highlight.find(params[:highlight_id])
else
@h = Highlight.find(params[:highlight_id])
@h.cleanup_images!(@h.id)
success = false
begin
@highlight_image =
HighlightImage.create(params[:highlight_image])
@highlight = Highlight.find(@highlight_image.highlight_id)
if @highlight_image.save
#success = true
end
success = true
rescue => ex
flash[:notice] = "There was a problem uploading your
HighlightImage photo. Please try again."
logger.error “Error occured while uploading a HighlightImage
for highlight #{params[:highlight_image][:highlight_id]}:
#{ex.message}”
logger.error ex.backtrace.join(“\n”);
end
end
respond_to do |format|
format.js do
if success
responds_to_parent { render :action =>
“create_image.rjs” }
end
end
end
end
Here is the view calling it:
_upload_image_form.rhtml:
<% form_for :highlight_image,
:url => url_for(:highlight_id =>
@highlight.id, :action => ‘create_image’),
:html => { :multipart => true, :target =>
‘upload_frame’ } do |form| %>
<%= form.file_field :uploaded_data %>
<%= form.hidden_field :highlight_id, :value => @highlight.id %>
<% end -%>
And here is the rjs call:
create-image.rjs:
page.call ‘closeCurrentOverlay’
unless @blank_data
page.replace_html “display_highlight_image”,
display_highlight_image(@highlight)
end
Here is the routing:
(from routes.rb)
map.resources :highlights do |highlight|
highlight.resources :highlight_images, :controller=>‘highlights/
highlight_images’
end
