local and global site manager, adapter and utility questions
by Tamer Higazi 11 Jun '13

11 Jun '13

Hi people! I have worked out so far the ZCA tutorial, and there are certain things for me not clear. 1. What is the difference between a global and a localSiteManager from the zope.component package?! How do I have to understand that a "globalSiteManager" resists in memory, and a localSiteManager is persistent ?! Could somebody of you explain it to me?! 2. What is the difference between an adapter and a utility ?! I register an adapter as well the same way as I do with a utility, and I query those 2 as well. But what's the point there?! For answering my questions, I would kindly thank you. Tamer

Problem with ZPsycopgDA and unicode-output
by Marcel Klapschus 15 May '13

15 May '13

I got a problem regarding the Database Output via ZPsycopgDA Adaptor in Zope 2.9: 1. My PostgresDB is encoded in UTF-8 2. My Z Psycopg 2 DB Connector is set to UTF-8 However the output of my db over the connector is somehow wrong encoded: An Example: In my utf-8 db it says: "Bitte auswählen" The db connector, however returns the following: print repr(dbstring) 'Bitte ausw\xc3\xa4hlen' As you can see, it looks like correct unicode, but in fact the leading "u" is missing and a check with instance(dbstring, unicode) returns FALSE! So actually it seems to give me an ordinary string but no real unicode-string! My Question: Is there any way to setup ZPsycopg2 DB Connector to return real unicode-strings from my DB? Regards Marcel
