I would like to use a select box to display and edit a boolean model
attribute. I realize that perhaps checkboxes or radio buttons are a
more idomatic way to do this in html but I would like to use a select
box.
What I want to do is to map the selected value in the box to the
existing value of the attribute when the form displays. I am having
trouble figuring out how do to this and the examples I can find are
not explicit enough for me to discern how this is done, or if it is
possible.
I have discovered that if one prefaces the select with the form
partial variable 'f' then one gets a series of obsure errors about an
undefined 'merge' method, while removing this and going with a bare
select call avoids the problem and otherwise seems to work. Odd, but
there it is.
Consequently, presently the structure looks something like this:
</b><br />
<%= select :is_invoicable,
[
['Yes', 'true' ],
['No', 'false' ],
],
{}, # select options
:id => 'select_is_invoicable',
:size => 1,
:title => 'May invoices be issued in this currency?'
-%>
</p>
What I want to accomplish, of course, is to have the current value of
is_invoicable (true or false) used to set the selected attribute of
the option to either Yes or No as appropriate. I nonetheless want
both options available in the drop down. I cannot seem to hit upon
the exact syntax to do this and the examples in the options_for_select
api do not provide me with much guidance. From them I gathered that
this would work:
],
currency_detail.is_invoicabe.to_s, # select options
:id => 'select_is_invoicable',
But that produces this in the view:
<select id="is_invoicable_YestrueNofalse"
name="is_invoicable[YestrueNofalse]">
<option value="false">false</option></select>
When what I was looking for was this:
<select id="select_is_invoicable" name="currency
[is_invoicable]" size="1"
title="May invoices be issued in this
currency?">
<option value="true">Yes</option>
<option selected="selected" value="false">No</option></
select>
I would really appreciate guidance on how this is done.
