Hello,
I am trying to make a category selection for an upload file so that a
category can be selected according to the file being uploaded. The model
and
upload is set up and I am able to select a category from upload.
The problem is: I am making an ‘add a category’ form handled by ajax
from
the upload view. From the set up I have given below, I am able to add a
category but can’t retrieve a selection field through Ajax. It gets
added
upon refresh. Please review the setup below:
In upload/new.rhtml view:
Upload form (excerpt):
<%= render :partial => 'categories/select' %>
<%= submit_tag :Create %>
<% end -%>Add category: <%= form_remote_tag :url => {
:action => ‘create_ajax’,
:controller => ‘categories’},
:loading => “new Effect.Appear(‘indicator’, {
duration: .3 })”,
:complete => “new Effect.Fade(‘indicator’, {
duration:
.3 })”,
:html => {
:id => “category_ajax_form”} %>
<%= text_field “category”, “title” %>
<%= submit_tag :Create %>
In categories/_select.rhtml partial:
<%= collection_select(“category”, @category, Category.find(:all), “id”,
“title”) %>
And lastly, in controller, categories_controller.rb
def create_ajax
@category = Category.new(params[:category])
if @category.save
replace_html render_partial ‘categories/select’
else
render category_path(@post), :layout => false
end
end
Thanks in advance. I am sure there is a way out.
