Ok, so I've decided to modify the source code in trytond, basically what I've done is create a new file named *modeljsonapi.py* in which I have a class that inherits from *ModelStorage, *in this new class I override the CRUD methods, in the *read *method I call my json API by using the requests<http://docs.python-requests.org/en/latest/index.html>module, from the HTTP json response I build the dictionaries to be returned, in all of the CRUD methods I also call the parents CRUD (based on the *ModelSQL*implementation). Then I created a module, which has an *Order *model, this model inherits from my new model type, *ModelJSONAPI* and declares a couple of fields, the module itself is registered correctly, I created a tree view for the Order model and expected to see the data (the tree view is rendered correctly) from the JSON API, how ever the model's read method isn't called as I've added logging statements to no avail, my assumption is that to determine if the read method will be called, trytond first searches for a list of (infered from the read method's signature) since there are no Order records the database it simply doesn't call it, am I correct?, Am I lost on my path? Thank you for your time. Regards, Tristian. -- [email protected] mailing list
