I don't think you really want that check on the model itself (i.e. in
the table) as from the sounds of it, you want the checkboxes to be
able to select multiple records for a particular action. What I have
done for a similar situation (I won't post the full code as it's quite
ugly), was something like this:
<form name="form_update_letters" #link this to a custom controller
action>
<div class="checkbox-controls">
<checkbox-controls form-name="form_update_letters" />
</div>
<table-plus fields="...">
<append-controls:>
<p param="checkbox">
<em>Select for action:</em>
<table-checkbox with="&this" />
</p>
</append-controls:>
<submit-button with="&'SelectToPrint'" /> # I used multiple
submits with different values to trigger different actions
</tabble-plus>
<div class="checkbox-controls">
<checkbox-controls form-name="form_update_letters" />
</div>
</form>
the helper tags I wrote:
<def tag="table-checkbox" attrs="checked">
<input class="table-checkbox" type="checkbox"
name="&this.class.to_s.downcase + '[]'" id="&this.class.to_s.downcase
+ '[' + this.id.to_s + ']'" value="&this.id.to_s" checked="&checked" /
>
</def>
<def tag="checkbox-controls" attrs="form-name">
<span param="label">Selections:<br /></span>
<span param="invert"><%= link_to_function "Invert",
"toggleCheckboxes(document.#{form_name}.getElements())" %></span>
<span param="clear-all"><%= link_to_function "Clear",
"clearCheckboxes(document.#{form_name}.getElements())" %></span>
<span param="set-all"><%= link_to_function "Check All", "fields =
document.#{form_name}.getElements(); clearCheckboxes(fields);
toggleCheckboxes(fields)" %></span>
</def>
<def tag="submit-button">
<input type="submit" name="submit" value="&this.titleize" />
</def>
Feel free to use as is if it helps. Basically, adds a regular
checkbox named after the item. Submitting I grabbed the submit value
which is the name and called different actions in the controller:
def update_letters
keys = params[:letter] unless params[:letter].nil?
case params[:submit]
when "Set As Spam"
...
After looking back at this, it seems there isn't a clean, simple way
to do this design pattern. Honestly, I'm not sure how one would even
go about adding that to hobo. Maybe a tweaked lifecycle or lifecycle
like pattern could do it? Then table-plus or another tag could create
the checkbox and a link for each mass assignment action.
