adding a caption by a form field?

[Adam Spiers]

Two of my ActiveScaffold-controlled models have fields which I have configured to be edited via <textarea>, and they are intended to receive Markdown-formatted text, so I wish to provide a link to http://daringfireball.net/projects/markdown/syntax at the top or bottom of the <textarea> in the #edit form.  How can I do this with ActiveScaffold?  I couldn't find anything in the docs; maybe I missed it.

Thanks,

Adam

You could set description, something like
conf.columns[:markdown_column].description = '<a
href="http://daringfireball.net/projects/markdown/syntax"
target="_blank">markdown syntax</a>'.html_safe

Thanks! That works ... but it also tries to insert the same
HTML into the <th> for that column in the #list action, which
causes serious HTML syntax / validation errors. Any ideas?

you can override render_column_heading

the link without using column.description
