Rails - Jul 2006 - Howto: Check_box with a variable (no model)

Hi,

I would like to put a checkbox on a form where the input field is a
variable rather than a field in a model.

The normal way (with a model) would be:

<%= check_box(''client'', ''accept'', {},
"1", "0")  %>

But since accept is a variable @accept and model client will not be
there, how do I make a check box work?

Regards,

Paul

Generally, you would use the same helper, but with _tag appended. So in 
this case, check_box_tag. It is detailed here : 
http://api.rubyonrails.com/classes/ActionView/Helpers/FormTagHelper.html#M000500
(well, the documentation is pretty sparse on this particular helper - 
but you should be able to figure it out.

Hi Pail, I hope this helps but this is how we did it:

<% $findrecord.each do |$findrecord| %>
<%
$array = TableRecords.find_by_sql(["select * from table_records where id 
= ?", $findrecord.id])

$recordrow = $array[0]
$recordid = $recordrow.id.to_s
$recordemail = $recordrow.email%>
<br /><%= check_box ("checker", "#{$recordid}", {},
"yes", "no")
%>&nbsp;&nbsp;<%=$recordemail%>
<% end %><br>

thanks,

Bing

Oops,

obviously I wasn''t reading the premise quite clearly, well, just have 
the check_box make a loop as many times as you want and you can pass a 
variable into the second field on the check_box helper.

I hope that was of any help.

thanks,

Bing

I think using check_box_tag would be a LOT easier, but that is just me :)

Hi,

Thanks for the help. I used check_box_tag and it worked just fine.

When I need a user to tick a "terms & conditions" checkbox, I use
a
check_box helper but in the model do ''validates_acceptance_of
:terms''
even though terms is not a field in the database.

I realise you don''t have a corresponding model, but thought
I''d throw this in.
