I can answer the jsi18n part: This is to do with loading translations for the javascript used in Admin. That is, this is loaded because there is <script type="text/javascript" src="/admin/jsi18n/..." /> in the loaded page somewhere. Why the model is initialized twice? Try: import pdb; pdb.set_trace() in the __init__ and you will see why that happens. - Anssi -- You received this message because you are subscribed to the Google Groups "Django users" group.
