Body
I have has_and_belongs_to_many association between two models. I made use of collection_select to represent the other model in this association in a form. When I tried to deselect options in collection_select, collection_select doesn't post its empty value and, thus, it doesn't let ActiveRecord pass any update clause to the database. e.g. Parameters are like; When onptions selected; Parameters: {"name_of_model"=>{"name"=>"de2", "other_model_ids"=>["1", "3"]} When none selected; Parameters: {"name_of_model"=>{"name"=>"de2" } Does anyone know a workaround for this?

Guidance

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
