Hi,
I have a form with a field name brand as :
<input type=''text'' name=''brand''>
now, using ajax I have to check if it is still available.
I am trying :
<%= link_to_remote "Check if it is available",
:update => ''avail'',
:url => ''check_brand''
%>
Now how do I pass the value of the field ''brand'' as as
argument to the
''check brand'' on server ?
Thanks.

i think you need the :with => ''#{brand}'' option.
<%= link_to_remote "Check if it is available",
:update => ''avail'',
:url => ''check_brand'',
:with => ''#{brand.id}''
%>

or :with => ''brand = #{brand.id}''
then you can check for params[:brand] in your controller.

Put the input into a form. Then either submit the form with form_remote_tag etc, or...

The above won''t work for a list of reasons. (Sorry, Jake, but the newbs need the list, to learn what to avoid!) Ruby won''t interpret single-quoted strings ''#{}'' as anything but strings containing literal hatches, braces, etc. That needed double quotes "" to invoke the sting #{embedding} system. Next, if brand.id existed, it would resolve at Ruby time, not at Ajax time, after a user changes the field. There might be some way to with=> a JavaScript string that fetches the field value into a named parameter, but I would just go with with => ''Form.serialize("my_form_id")''. -- Phlip http://c2.com/cgi/wiki?ZeekLand <-- NOT a blog!! --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This is what is in controller :
def check_brand
brand=params[''brand'']
textbrand = Textbrand.look_by_textbrand(brand)
if textbrand.nil?
# valid
render :text=> ''It is available.''
else
render :text=> ''It is already taken.''
end
end
and this is in view :
<tr>
<td height="26" colspan="3"
valign="top">
<input onfocus="this.value='''';"
id=''brand'' maxlentgh=15
name="brand" type="text" value="(max 15 chars)"
class="c11">
</td>
<td colspan="3"/>
</tr>
<tr>
<td height="24" colspan="3"
valign="top">
<%= link_to_remote "Check if it is available",
:update => ''avail'',
:url => ''check_brand'',
:with => ''brand=#{brand.id}''
%>
</td>
<td colspan="3"/>
</tr>
<tr>
<td height="3"/>
<td colspan="5"/>
</tr>
<tr>
<td id=''avail'' width="38%"
rowspan="2" colspan="3"
class="c16"></td>
<td height="16"/>
<td colspan="2"/>
</tr>
And it is not working. Any help is greatly appreciated.

Still, none of the above ideas work. The field is in a form but I don''t need to submit the form now. Just check availability and go ahead with the rest of the form. -- Posted via http://www.ruby-forum.com/. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

<%= link_to_remote ''check'' ,
:update => ''avail'',
:url => {:action => ''check_brand''} ,
:with =>"''brand=try''"
%>
This works with the hardcoded value of try. But how do I put the value
of field ''brand''.

Rm Rm wrote:> The field is in a form but I don''t need to > submit the form now. Just check availability > and go ahead with the rest of the form.I haven''t seen the controller / view code you''re using to render the form but, based on what you''ve posted, I assume you''re iterating through a collection of records and rendering a table row for each one using something like @brands.each do |brand| ... end If that''s the case, then in the view code you''d use ... <%= link_to_remote("Check if it is available", :url => {:action => ''check_brand'', :id => brand.id}, :update => ''avail'') %> and in the check_brand action you''ll need to change to brand = params[:id] Note that this will get you to the point where the code in the controller gets executed. However, the update in the browser will not happen correctly if my assumption above about iterating through a collection is correct, given the code you''ve shown so far. DOM elements have to have unique IDs. It looks to me like each row in your table is going to have a <td> with an id=''avail''. Another source of potential difficulty will be your use of tables for layout. I think the <td> can be updated, but can''t remember for sure. I''ve quit using tables because of all the hacks and workarounds needed to use them with ajax. hth, Bill --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

This worked !! Thanks to all of you . And a big thanks to
''Ajax on Rails'' by Scott Raymond which actually had an example
similar
to my problem.
