javascript - Odd behaviour when attempting to delete/destroy a user -

i'm coming across odd behaviour when seek delete user project in rails.

briefly, have link in view allows admin user delete user:

<%= link_to 'delete user', user, :method => :delete, :confirm => "are sure?" %>

and here code in user controller:

# delete /users/1 # delete /users/1.json def destroy @user = user.find(params[:id]) @user.destroy respond_to |format| format.html { redirect_to users_url } format.json { head :no_content } end end

however, while user deleted, popup "are sure?" box appears twice, , next error appears:

activerecord::recordnotfound in userscontroller#destroy couldn't find user id=xxx

where "xxx" user id has been deleted.

doing bit of searching, people have suggested way javascript loaded in project, , perchance conflict jquery (i using jquery-rails gem). however, application.html.erb file seems fine:

<%= stylesheet_link_tag "application","http://ajax.googleapis.com/ajax/libs/jqueryui/1.8/themes/smoothness/jquery-ui.css" %> <%= stylesheet_link_tag "application", :media => "all" %> <%= javascript_include_tag "application" %> <%= csrf_meta_tags %>

as application.js file:

//= require jquery //= require jquery_ujs //= require jquery-ui //= require_tree .

so, i'm not sure why happening - first time i've encountered error.

anyone point me in right direction?

thanks!

you have 1 of library loading jquery twice. happened me before, think activeadmin @ time had different jquery dependency , jquery loaded twice , doubled calls.

your user error because user has been deleted sec time, can't find it.

javascript jquery ruby-on-rails
