Checkboxes

Rails
1

in the mean time i am using a checkbox like this :

<input type="checkbox" name="var[car]" <%= var.car ?  'checked' : ''

unless @var == nil %> />

but i am sure there is something better than this in rails like
<%= checkbox_tag ‘var’, ‘car’, :checked => true %>

but this is not working
any help

thanks

…thank but aside from that the checkbox to be checked if @var.car
(which is type tinyint1 in mysql) is true and unchecked if false. how do
i make that behaviour? i saw something like :checked => true but it
didn’t really worked. haven’t found anything in wiki either

thanks again

If you set the below in your controller, that should do what you
require.

@var.car = 1

yes, but i do not want all the checkboxes to be checked but if there is
someone who sees this information in ‘edit’ - depends when he was
created and if someone set car = 1 - then the checbox will be
automaticly checked (like the html tag # this is a checked box
thanks again

Does this do what you need?

<%= check_box_tag “var[car]”, @var.car, 1 %>

this work perfect:

<%= check_box “page”, “sent”, :checked => @page.sent %>

thanks for your help!
(sent is tinyint boolean)

Assuming ‘car’ is an integer value, where 0 is unselected and 1 is
selected, the
following should do:

<%= check_box :var, :car %>

If it’s, let’s say, a ‘yes’/‘no’ string, do something like this:

<%= check_box :var, :car, {}, ‘yes’, ‘no’ %>

then checked status is already automatically determined by calling
@page.sent, which is expected to return 0 (unchecked) or a non-zero
integer (checked). If you change the above to :checked => 0, you’ll
still find that the box is unchecked unless @page.sent returns 0.

s/unchecked/checked/ on last line.

I believe the :checked spec is ignored. If you just do:

<%= check_box “page”, “sent” %>

then checked status is already automatically determined by calling
@page.sent, which is expected to return 0 (unchecked) or a non-zero
integer (checked). If you change the above to :checked => 0, you’ll
still find that the box is unchecked unless @page.sent returns 0.
