Optionnal message labels

Some javascript is used in the demo frontend to format the messages label: templates/instant/event_class_format.js.

Some css classes are defined in instant/static/instant.css. To customize:

{
'default' : 'mq-label mq-default',
'important' : 'mq-label mq-important',
'ok' : 'mq-label mq-ok',
'info' : 'mq-label mq-info',
'debug' : 'mq-label mq-debug',
'warning' : 'mq-label mq-warning',
'error' : 'mq-label mq-error',
'object created' : 'mq-label mq-created',
'object edited' : 'mq-label mq-edited',
'object deleted' : 'mq-label mq-deleted',
}

Default icons (using font-awesome):

{
'default' : '<i class="fa fa-flash"></i>',
'important' : '<i class="fa fa-exclamation"></i>',
'ok' : '<i class="fa fa-thumbs-up"></i>',
'info' : '<i class="fa fa-info-circle"></i>',
'debug' : '<i class="fa fa-cog"></i>',
'warning' : '<i class="fa fa-exclamation"></i>',
'error' : '<i class="fa fa-exclamation-triangle"></i>',
'object edited' : '<i class="fa fa-pencil"></i>',
'object created' : '<i class="fa fa-plus"></i>',
'object deleted' : '<i class="fa fa-remove"></i>',
}
