[Erp5-dev] Programatically rendering documents

[Jacek Medrzycki]

Hi.

When I call an ERP5 object, I get the html representing the rendered
view of the object. The code is similar to the following:

obj = portal.restrictedTraverse(object_path)
html_repr = obj()

and here html_repr contains html code.

It works for almost all Portal Types, except for Payment Transaction, in
which case html_repr is like following:
http://localhost/erp5/accounting_module/9/view?portal_status_message=Accounting%20Transaction%20Line%20added.&selection_index:int=0&selection_name=

This looks like a kind of redirect. The "portal_status_message" part
sugggests that Transaction Line was created and, indeed, it was! But
why? Shouldn't a object_view action be called when an object is called?
Why the Transaction Line is beeing created? No object_view action
creates Transaction Line, as I see. How can I render programatically the
Payment Transaction?

TIA
Jacek

This behaviour is not garanteed. For example, File behaves differently.
You can not rely on the fact that obj() will render the default view of
an object.
Use instead
obj.view()

BTW, using abbreviations is not conformant to ERP5 naming conventions.

obj -> object
html_repr -> html_representation

Please refer to naming conventsion for explanation.

No idea for this one. Anyway, calling __call__ is not the appropriate way.
Can you please try view() instead. Based on the results, I may search
for you what is going on.
