for a delete button next to the image in the views, i think you can achieve
it using A built in helpers.
e.g. not tested
in views for delete button
{{=SPAN(A(I(_class='icon-remove'), callback=URL('function_callback',
args=image.id)),
delete='tr', _title='Remove Image' % p.name, _class='btn btn-danger'))}}
in view for ajax form
<form id="myform">
<input type="file" name="image" id="image"><br>
<input type="submit" />
</form>
<script>
jQuery('#myform').submit(function() {
ajax('{{=URL('function_callback')}}',
['image'], ':eval');
return false;
});
</script>
and in controllers :
def function_callback():
record = db.person(request.args(0)) or redirect(URL('index'))
form = SQLFORM(db.image, record)
if form.accepts(request, formname = None):
return DIV("Image uploaded")
elif form.errors:
return TABLE(*[TR(k, v) for k, v in form.errors.items()])
