Ruby On Rails 3 submit form AJAX update results in div
I am stuck; I did a search and I can't find a pointer on how to get this project to work. I have a form on my index.html.erb as:
<html> <head>
<title>Ajax List Demo</title> <h1>Listing posts</h1>
<%= javascript_include_tag "prototype" %> </head> <body>
<h3>Add to list using Ajax</h3>
<% form_tag ( :remote=>true, :update => 开发者_运维知识库'my_list', :action => :list , :method=>:post, :format =>:xml ) do %>
Enter the url:
<%= text_field_tag 'url' ,'', :size => 80 %>
<%= submit_tag "Find" %>
<% end %>
<div id="my_list"><%= render :partial => 'profiles/list' %></div> </body> </html>
Now I have a div with this called my_list. When I submit the form I want my partial _list.html.erb (inside profiles dir, tried home dir too) to update with the results of list.
My home controller has this method:
def list
puts "here!!!!"
reader = Reader.new
@profiles = reader.processURL(params[:url])
render :partial=>'profiles/list', :locals => { :profiles => @profiles}
end
I end up getting this error:
ActionView::MissingTemplate (Missing partial profiles/list with {:locale=>[:en, :en], :handlers=>[:rjs, :builder, :rhtml, :rxml, :
erb], :formats=>[:xml]} in view paths "C:/Users/....tree/app/views"):
app/controllers/home_controller.rb:22:in `list'
Rendered C:/Ruby187/lib/ruby/gems/1.8/gems/actionpack-3.0.0/lib/action_dispatch/middleware/templates/rescues/missing_template.erb
within rescues/layout (1.0ms)
Could anyone help me or send me in the right direction to understand how to update a div rendering via Rails on form submit? Thanks again.
First of all I am getting ajax to render(@homepages) in index.html.erb via index.js.erb OK, but my search to update @homepages is not working.
In your javascript_include_tag you missed out rails.js which I think handles the ajax request. javascript_include_tag :defaults would have done all that for you plus some others that you do not need. Providing you are not using jquery you need prototype and rails.js as a minimum.
I do not think the format of this form_tag is correct:
<% form_tag (:remote=>true, :update => 'my_list', :action => :list , :method=>:post, :format =>:xml) do %>
The first value after the "(" should be the item_path, then the conditions :action => :list.
:method => post should take you to the create or new action.
:update => 'my_list' would be done in the list.js.erb using javascript (prototype)
The code for jquery and prototype is similar, but slightly different (see Railscast 205)
Why format xml in the form_tag, put it in the controller "list" mine is:
respond_to do |format|
format.html # index.html.erb
format.xml { render :xml => @homepages }
format.js
end
Don't sure if you can get away with 'url' should not it be :url you might be able to use either.
When I was getting the missing template it was because it was looking for a search.html.erb file. In your case it is looking for a list.html.erb.
