Could not find engine name for tgext.admin.templates.bootstrap_form_layout

[Neil Ablang]

Hello,

I am having trouble with the built-in admin facilities for turbogears 2.3.2

I followed the following steps in setting up

1. virtualenv --no-site-packages zigbee

2.cd zigbee

3.source bin/activate

4.pip install tg.devtools

5.gearbox quickstart zigbee

6. cd zigbee/

7. python setup.py develop

8.  gearbox setup-app
9. gearbox serve

I have the following error when trying to edit a user once logged in as manager, and using the admin tool.

Below is the error:

The debugger caught an exception in your WSGI application. You can now look at the traceback which led to the error.

To switch between the interactive traceback and the plaintext one, you can click on the "Traceback" headline. From the text traceback you can also create a paste of it. For code execution mouse-over the frame you want to debug and click on the console icon on the right side.

You can execute arbitrary Python code in the stack frames and there are some extra helpers available for introspection:

• dump() shows all variables in the frame
• dump(obj) dumps all that's known about the object
• ctx the context of the failed request

Which engines is your project using? Check in app_cfg.py that engines and default_engine are one of mako, jinja or genshi. Those are the only one supported by the admin.

Also check that you have the latest version of tgext.crud and tgext.admin, try to update them to be sure you have the last one.

Did you also check that tgext.admin and tgext.crud are updated to the last version?  There was a release with missing template files on pypi due to errors during packaging. It got removed but It might be that you installed that one

[Neil Ablang]

Hi Alessandro,

Where to download the newest version for files  tgext.admin and tgext.crud? I m using pip /easy_install to fetch my files for now

BR,

Neil

[Alessandro Molina]

Yes it's right to download it from pypi. Just check you have the latest version

Pointing out that tw2 seems to have issues loading template from egg installed as zip files, so make sure you have tgext.admin installed as a directory egg or using pip, otherwise ToscaWidgets might have issues finding the template.
