Declarative Panels Not Being Loaded

[Antony Owino]

Hello,

Struggling get to panels executed, i.e. Pyramid renders None instead of panel content. I have the following code in myapp/__init__.py

@event_source

def configure_panels(config):

config.include("pyramid_layout")

@event_source

def configure_views(config):

...

# adds cornice

config.include("cornice")

# adds panels

config.include("pyramid_layout")

from . import panels

config.include("myapp.panels.dashboard")

config.scan(panels)

from . import views

config.scan(views)

def main(global_config, **settings):

"""This function returns a Pyramid WSGI application."""

with Configurator(settings=settings) as config:

# Core view and layout related

...

configure_views(config)

configure_panels(config)

...

Which is supposed to load views and panels but the panels are not executed. 

What works is manually adding a panel in myapp/panels/dashboard/__init__.py i.e.:

def includeme(config):

"""Configure dashboard panels."""

config.include("pyramid_layout")

# !!! This does not work

# I have an empty __init__.py in the panels/dashboard module

config.scan("myapp.panels.dashboard")

# Manual panel addition (only this works)

config.add_panel(

"myapp.panels.dashboard.dashboard.test_panel",

name="test_panel",

renderer="string",

)

I'd really prefer adding the panels declaratively. Thank you all in advance.

You don't show the @panel_config but assuming it's within the boundaries of one of your calls to config.scan() then the issue is that pyramid's "scan" function by default scans for "pyramid" decorators and pyramid_layout registers its decorators under the "pyramid_layout" category. This means you should adjust your scan for panels to include that category:

    config.scan("myapp.panels", categories=("pyramid", "pyramid_layout"))

See https://github.com/Pylons/pyramid_layout/blob/202a291bbb947e7f5c43c5216878331987508f05/pyramid_layout/panel.py#L36 and https://docs.pylonsproject.org/projects/pyramid/en/latest/api/config.html#pyramid.config.Configurator.scan.

Ah, thanks so much, that worked like a charm!! Good to know I can pass
in a tuple to Venusian - I missed that while stepping through the
debugger earlier. And thank you for the references.
