hi, i have a question about partial templates. there is a table - Topics, it has one field - Title. there is a text_field form with button, and a partial template under the form. they are in the same template. the partial can display Titles which is already in the Topics table. user enter a string in the form, click the button. the string will save as Title in Topics table. the partial will display all the data from the Topics table, including the string which user just entered. i have been thinking all day, but can''t find a solution. can someone help, give me a solution. thanks very much! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

What I have done is to wrap my partials inside of divs with an id value ''name_of_div_where_partial_is''. I used the form_remote_tag helper to add to the list without reloading the whole page. Then you can do one of two things: 1) In the method that is called when you hit the submit button you save the new Title and then quary to get the old titles and the new title. Then, you should have the partial already set-up so that variable is being used to dsiplay the title in that partial. Add the :update option to the form_remote_tag and it should update without reloading the whole page: <%= form_remote_tag :update => ''name_of_div_where_partial_is'', . . . %> or, 2) In the method that gets called when you hit the submit button you can use the render method with the :update attribute. So something like: render :update do |page| page.replace_html ''name_of_div_where_partial_is'', :partial => ''name_of_partial'' end What this does it is says to redisplay the partial in the div overwriting the html currently there. I use the second way to update a group of two lists that I have on a single page, where I remove one item from a list that then automatically gets added to the second list of removed stuff.

i created a highlight.rjs file, which including highlight javascript code. the highlight code needs to know which is the new entered object. so i transfered the new object''s id to it. View: <%= javascript_include_tag :defaults %> <% remote_form_for :user, :url => {:action => :highlight, :id => @user}, :update => ''name_of_div_where_partial_is'' do |f| %> <%= f.text_field :name %> <%= submit_tag "Add" %> <% end %> <div id = ''name_of_div_where_partial_is''> <%= render(:partial => "show", :collection => @users) %> </div> Controller: def index @user = User.new(params[:user]) if request.post? @user.save end @users = User.find(:all) end def highlight @user = User.find(params[:id]) end loading the index page, it works well. but after i enter a new name, click submit, partial shows "Couldn''t find User without an ID". the user ID didn''t transfer to the highlight method -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
