Ruby and rjs

Rails
1

Hi all…

Can we write ruby code directly in an rjs file?

I have to replace a div with

<%= text_field “ciclass”, “name”, “size” => 20, “value” => @class_name,
:readonly => “readonly” %>
<%= hidden_field “ci”, “ci_class”, “value” => @class_id %>

For doing this i’ve to write the above code in a partial file and
update the div as follows in the rjs file as shown below:

page.replace_html “div_name”, :partial => “partial_file_name”

I was looking for a simpler way so that i can avoid writing a partial
file for the above 2 lines.

Is there any way to write the above code directly in rjs file?

Please help

Thanks

rjs files themselves might be overkill. I have never needed to do
anything but
this, straight out of a controller:

render :update do |rjs|
rjs.replace_html “div_name”, :partial => “partial_file_name”
end

(The variable that’s usually called ‘page’ I renamed to ‘rjs’, because
the
Interthing already has too danged many variables in it called ‘page’.)

And I would not hesitate to write a two-line partial. But you might get
by with
an inline:

rjs.replace_html “div_name”, :inline =>
“<%= text_field ‘ciclass’, ‘name’, :size => 20,
:value => #{@class_name},
:readonly => “readonly” %>
<%= hidden_field ‘ci’, ‘ci_class’, :value => #{@class_id} %>”

Instead of stomping out an entire div (and possibly twitching the user’s
keyboard focus) can’t you just update those fields’ values directly?

Hi…

I solved the problem by writing a 2 line partial file and rendering it
in rjs file.

I tried to update those field values alone directly. I have some other
fields in the form. So when i select their value, the above updated
value is not shown.

So i did it this way
