Hi,
I have a tabular (it’s a form actually) with text_fields and buttons.
I wanted to diplay a particular row when a button is set to ‘yes’.
Everything’s working fine except, that my new row is diplayed at the top
of the array and not where I want. I can do page.add_html/delete and
specify bottom, but I don’t understand why my snippet doesn’t work.
Any idea?
Used to programming in Ruby? |
<%= radio_button :form,:ruby,:yes, :onclick =>
remote_function(:url => {:controller => '/my_controler', :action
=>'my_action', :ruby => 'yes'}, :method => :post)%> |
<%= radio_button :form,:ruby,:yes, :onclick =>
remote_function(:url => {:controller => '/my_controler', :action
=>'my_action', :ruby => 'no'}, :method => :post)%> |
<%= render :partial => 'yes' %>
And the partial yes:
<% if @ruby -%>
bla bla bla ../.. |
<% end -%>
With the rjs
page.replace_html ‘my_id’, :partial => ‘yes’
Thanks!

Hi Pierre,
This looks perfectly correct to me. I do something similar but with an
unordered list, and div’s around each of the
lines. replace_html
cleanly replaces just the line I want to change. I wonder if it is just
a bug related to tables. I almost never use a table anymore now that
I’ve learned css.
best of luck,
jp
Thanks for your reply.

I have the same snippet for lists too and it works actually.

Maybe. I’m waiting for other replies before going deeper in this problem
to see where’s the bug. I’m wondering if it is due to the ‘form’ fields.

Actually, I have an application displaying a whole bunch of data (think
of
thousands rows/columns of structured data). So tabulars are perfect for
me

<%= render :partial => 'yes' %>
the above is not valid html. applying your partial, it’s even more
invalid.

that’s not going to work and your browser will screw up the rendering,
but you already know that.
try:
<%= render :partial => 'yes' -%>
And the partial yes:
<% if @ruby -%>
bla bla bla ../.. |
<% end -%>
rjs stays the same
keep in mind the # of td’s in your partial should be the same as the
rest of the table, or have a colspan attribute.

It’s not a bug with tables. Ajax works on XHTML DOM elements. Tables
use a
different DOM. The explanation of the situation is on MSDN. If you’re
going to use Ajax, you’re either going to use CSS, or you’re going to
end up
with some very ugly code because
's can’t be updated / replaced. If
you
really need to use tables, the best way I’ve heard of is to replace your
structure with
It seems you can do a page.replace on a
. I haven’t tried it.
My
recommendation is to bite the bullet and learn a little CSS. You can
use
absolute positioning on an to get the table effect very easily,
your
code will be lots cleaner, and you can style the result in ways you’ll
never
be able to with a table. OTOH, I hear the XHTML DOM is going to be
extended
and CSS3.x is going to include tables. If you can wait
Best regards,
Bill

It works! Thanks a lot!

Actually the colspan was already there

Unfortunately, it doesn’t work either :’( I will forget about this AJAX
trick.

You’re probably right, but at this point on I don’t have the time to
learn
CSS and replace the 200 tables of my application
Maybe in the RC2…

I’m pretty sure my customers can’t wait!
Thanks for your explanation,
