Is there a reason that you are using ZPsycopgDA instead of ZPygresqlDA? You should set the two environments up identically. > But still when I import my project’s source code (i.e. .zexp file) from > live to dev m/c all the code is imported successfully except it gives > errors in Pygresql_Database_Connection & OpenFlow. > > For Pygresql_Database_Connection & Openflow it gives error as ‘This > object from PygresqlDA product is broken’ & ‘This object from OpenFlow > product is broken’ respectively. > If you are importing a zexp that contains a ZPygresqlDA connection and the ZPygresqlDA product is not properly installed, you will indeed have broken objects - that would apply to ZPsycopgDA too, of course. If you want to use the imported objects, you must have the same products installed (at the same versions). I don't know anything about ZPygresqlDA (or OpenFlow, for that matter), but I've had similar problems with ZPsycopgDA, so the following may be of some help: - First, is your DA correctly installed? Take a look at the Control Panel in the ZMI, and scroll down to the DA itself - does it have a "broken product" icon? If so, this may be because the associated python-level product (which would be Psycopg itself in the case of ZPsycopgDA) is not correctly installed. N.B. You may have to install libpq-dev to compile it. Second, is the DA actually usable? Even if it appears installed properly in the Control Panel, it's worth testing by setting up a new connection to your database. If you have a good setup, and the error is still thrown, you would still need to zap the old product's connection and replace it with the new product's equivalent, of course Formally, you are on your own importing a zexp file into a target environment that differs from the source environment. If the above does not help, then I'd go back and make the necessary changes to make them match before spending a lot of time on this.
