in a rails habtm, can't remove final item?
davev opened this issue · 5 comments
don't know if this is BSM or Rails, but if there is only one associated record, if you click "remove" and save the form, the corresponding record in the join table is NOT removed. works perfectly until you get down to the edge case of only one record left. also works correctly if you remove that record and add another before saving. ideas? tia.
Please try to sort out if this this is a bsmSelect defect, provide a standalone script showing the defect and I'll look into this.
it's not BSM. i've duplicated the same behavior in Rails, (with Formtastic) using a regular multi-select dropdown. thanks.
figured out the answer - it's because multiselects aren't submitted by browser if no options are selected.
it's good you have solved your issue and thanks for giving feedback.
Yes, it's a "native behavior". But you can solve this problem easily.
When none of the check boxes are selected, nothing is submitted. So you must add this hidden field at the end of form (example)
<%= hidden_field_tag "user[company_ids][]" %>
