Here’s what I’ve got now as the invoice list part of my form:

f.subform(:items, {:grid=>true, :labels=>["#", "SKU", "Name", "Price Ea.", "Shp.", "Disc.", "Tax"]}) do
f.input(:quantity, :size=>6)
f.input(:sku_id, :size=>8)
f.input(:name, :size=>70)
f.input(:price, :size=>8)
f.input(:shipping, :size=>8)
f.input(:discount, :size=>8)
f.input(:salestax, :size=>8)
f.tag(:td) <<f.tag(:a, :href=>'deleteitem?id=') << “Delete”
end

It would have been nice to do
f.input(:name, :label=>”Name”)
but I don’t have a problem with the individual inputs’ labels being ignored when :grid is true.

Now, you said earlier

I've pushed a couple new commits that will make :labels=>nil or :labels=>[] not add a header row.

That’s not the problem. There’s STILL an “Items” header floating on top of the column header row. Or, rather, there’s a caption there. Neither :caption=>”” nor :attr=>{:caption=>””} would banish the damn thing.

But my key query for this message is the last line.

f.tag(:td) <<f.tag(:a, :href=>'deleteitem?id=') << “Delete”

What’s missing is the bit I need to put after id=

That would be the primary key for the item. How do I access that? My existing solution is to once again process the XML after the form is built. I find the hidden that contains the ID, and build the link with that value:

row.elements.each("//[@name]"){|zed| if zed.attributes['name'].match(/id$/) then row.children.last.add_element(pit(:td){link('deleteitem?id=' + zed.attributes['value'] ){'Delete'}}) end }

This will be harder with Forme since I don’t get back the subform as an array with one row per array element; I’ll have to first detect and isolate each row before extracting the ID and adding the delete link.

Or I could . . . .?

Agreed, but it's not really possible to do that, at least if you use the
block form (they could theoretically be pulled out of the :inputs option if
you provide an options hash).

Now, you said earlier

:legend=>nil should do that.

row.elements.each("//[@name]"){|zed| if
zed.attributes['name'].match(/id$/) then
row.children.last.add_element(pit(:td){link('deleteitem?id=' +
zed.attributes['value'] ){'Delete'}}) end }

You can access the object for the form via f.obj. I'd use the following
form here:

f.tag(:td){f.tag(:a, {:href=>"deleteitem?id=#{f.obj.id}")}, ['Delete']}

This will be harder with Forme since I don’t get back the subform as an
array with one row per array element; I’ll have to first detect and isolate
each row before extracting the ID and adding the delete link.

f.obj will change inside the subform block, so the above code should work
correctly.

Thanks,
Jeremy

That didn’t work. {puzzled}

"undefined local variable or method `f’"

Looks like the syntax was a little off, but this should work:

f.tag(:td){f.tag(:a, {:href=>"deleteitem?id=#{f.obj.id}"}, ['Delete'])}

I don't really understand why you got the error message you did, though,
unless f isn't referencing the current Forme::Form object. I'm assuming
you are running this inside a "Forme.form(obj, ...) do |f| ... end" block.

Thanks,
Jeremy

I was. I’m just a doofus. I’d used single quotes, thus inhibiting the #{xxx} expansion.
