Hi all, I have a table with link_to_remote on each row that changes the status of the object represented by that row. I was wondering if it is possible to use the :update flag to update a <tr>? When I tried it the results just get stuffed into the first column with the rest of the columns blank. Thanks, Andy
Use the link_to to update a div and put the div(''s) around the
objects you want to update - regardless of whether they''re
TR''s or
other.

At least I''ve never gotten it to work. If there is some trick to make it work I''d like to hear about it.

I think that I have come across something similar whaen using Insertion.Bottom(). I think it has something to do with using innerHTML on tables in IE, using document.createElement() worked for me, though it made the code rather more complicated.

If there is some trick to make it work I''d like to hear > about it.You don''t need to use a <div>, just give your element to be updated an ID, and you''re good to go. The update parameter will update any DOM object with the matching ID. From api.rubyonrails.com: link_to_remote(name, options = {}, html_options = {}) Returns a link to a remote action defined by options[:url] (using the url_for format) that’s called in the background using XMLHttpRequest. The result of that request can then be inserted into a DOM object whose id can be specified with options[:update]. This is the same for form_remote_tag etc. In response to the original poster: I would guess that the reason your results are all appearing in the first column is that you forgot to put enough <td> tags and so on into the partial you are rendering with your link_to_remote call. You need to have it generate the HTML for everything inside the <tr> tags you are trying to update, which will include every <td> in that row. If you''re trying to update just one <td>, give that an ID instead and leave the rest of the row as it is. I reckon that should solve it. ~Dave -- Dave Silvester Rent-A-Monkey Website Development Web: http://www.rentamonkey.com/
Thanks all. I''ve resolved the problems I had with the result of the update going into a single cell. The problem was due to my action rendering a partial with a bug in it. It contained the element with the ID that I was updating (in my case the <tr id=>) when it shouldn''t have. And by following http://dev.rubyonrails.com/ticket/2137, now I have a table that contains edit links that changes a row into a form with save links that redisplay the row after the update is saved.
