Update/Edit from list views

[ChristopheB]

Hi,

I'd like to have an edit button in front of each row of my list.
Even after googling a lot I can't find out to properly do it.

I am trying the following starting from the generated method but cannot find how to handle the version number (e.g. locking).

List view:

<g:each in="${internalNoteInstanceList}" var="item">
		<tr>
			<td>
				<a href="${createLink(controller:'internalNote',action:'update',id:''+item.id)}">
					<g:img dir="images" file="edit.png" />
				</a>
			</td>

Controller:

    def update(Long id, Long version) {
        def internalNoteInstance = InternalNote.get(id)
        if (!internalNoteInstance) {
            flash.message = message(code: 'default.not.found.message', args: [message(code: 'internalNote.label', default: 'InternalNote'), id])
            redirect(action: "list")
            return
        }

        if (version != null) {
            if (internalNoteInstance.version > version) {
                internalNoteInstance.errors.rejectValue("version", "default.optimistic.locking.failure",
                          [message(code: 'internalNote.label', default: 'InternalNote')] as Object[],
                          "Another user has updated this InternalNote while you were editing")
                render(view: "edit", model: [internalNoteInstance: internalNoteInstance])
                return
            }
        }

        internalNoteInstance.properties = params

        if (!internalNoteInstance.save(flush: true)) {
            render(view: "create", model: [internalNoteInstance: internalNoteInstance])
            return
        }

        flash.message = message(code: 'default.updated.message', args: [message(code: 'internalNote.label', default: 'InternalNote'), internalNoteInstance.id])
        redirect(action: "show", id: internalNoteInstance.id)
    }

Hi,

Try something like this, you should be able to access it by item.version:

def update = {
    def internalNoteInstance = InternalNote.get(params.id)

Then in your view you pass them like this:

    <g:createLink controller="internalNote" action="update" params="[id: '${item.id}', version: '${item.version}]"/>
