Using Kotti side-by-side with another Pyramid app

[Andreas Jung]

Hi there,

here is my scenario: I am currently rewriting the produce-and-publish.com website

using Pyramid where the main part of the application is already implemented

with some views and interactive features using Twitter Bootstrap. Now I want to maintain

some editorial content through a CMS (Kotti) and aggregate the content in order to show it up

inside my own main application.

Is 

http://kotti.readthedocs.org/en/latest/developing/as-a-library.html

the right way using Kotti as a "secondary" application besides my own "primary" application?

If yes then I have a slightly problem with the pipeline configuration. I get the following error

sucmac:pp-demo ajung$ ../bin/pserve development.ini

Is there anything I am missing or am I on the wrong trail? Or is there a better way

integration two different Pyramid applications into one? What I don't want is using 

Kotti as a "primary" app and rewriting my own code in order to make it work with Kotti.

The right way of using Kotti as a separate WSGI app completely would
be to use something like Paste#urlmap [1], so the two apps would map
to different URLs. (Your app might map to /, Kotti to /cms.)

You should then be able to pull content from Kotti using
kotti.DBSession and display it in your app.

Using the 'as-a-library' approach that you link to is really
equivalent to writing a Kotti add-on (but having a little more
control), so it's not what you want apparently.

[1] http://pythonpaste.org/deploy/#composite-applications

The problem with your specific configuration is that it defines two
"main" entry points for the app: "[app:main]" and "[filter:main]". If
you were to use a single app and integrate with Kotti (which you say
you want to avoid), you'd merge your "[app:main]" and "[app:myapp]"
into one.

But using Paste#urlmap, as discussed above, your configuration should
look something like this:

[composite:main]
use = egg:Paste#urlmap
/ = pp
/cms = kotti

[app:pp]
use = egg:pp-demo
# ... Your app's configuration

[pipline:kotti]
pipeline =
fanstatic
kotti-app

[filter:fanstatic]
use = egg:fanstatic#fanstatic

[app:kotti-app]
use = egg:kotti
# ... Kotti configuration

# ... and then [server:main] and the rest ...

Using the urlmap approach seems to the right path but there is still one thing missing.

I am get to the "Welcome to Kotti" page through /cms but I can not get to the Login page which is /wired

to /edit. 

My configuration is:

[composite:main]

use = egg:Paste#urlmap

/ = mainapp

/cms = kotti

[app:mainapp]

use = egg:pp-demo

pyramid.reload_templates = true

pyramid.debug_authorization = false

pyramid.debug_notfound = false

pyramid.debug_routematch = false

pyramid.default_locale_name = en

pyramid.includes = 

[app:kotti]

use = egg:kotti

sqlalchemy.url = sqlite:///%(here)s/Kotti.db

#mail.default_sender = yourname@yourhost

kotti.configurators = kotti_tinymce.kotti_configure

kotti.site_title = My Kotti site

kotti.secret = qwerty

#[filter:fanstatic]

#use = egg:fanstatic#fanstatic

#[pipeline:main]

#pipeline =

#   fanstatic

#  kotti

[server:main]

use = egg:waitress#main

host = 0.0.0.0

port = 6548

and the initialization code is:

from pyramid.config import Configurator

default_settings = {

    'pyramid.includes': 'myapp myapp.views',

    'kotti.authn_policy_factory': 'myapp.authn_policy_factory',

    'kotti.base_includes': (

        'kotti kotti.views kotti.views.login kotti.views.users'),

    'kotti.use_tables': 'orders principals',

    'kotti.populators': 'myapp.resources.populate',

    'kotti.principals_factory': 'myapp.security.Principals',

    'kotti.root_factory': 'myapp.resources.Root',

    'kotti.site_title': 'Myapp',

}

def main(global_config, **settings):

    """ This function returns a Pyramid WSGI application.

    """

    settings2 = default_settings.copy()

    settings2.update(settings) 

    config = Configurator(settings=settings2)

    config.add_static_view('static', 'static', cache_max_age=3600)

    config.include('pyramid_mailer')

    config.add_route('home', '/')

    config.scan()

    return config.make_wsgi_app()

What is missing here?

Hi Andreas!

What do you mean about not getting the login page? Are you refering to
'login' button on the "Welcome to Kotti" page itself?
If so then that is an hard coded link that is editable. There you'll
need to modify it to '/cms/edit'

That "Login" link was wrongly pointing to an absolute path. I've
fixed it here:


https://github.com/Pylons/Kotti/commit/973949b6bd24449d25f027b062d35e4aad36befe

Note that this is just the sample initial page though, so you can hit
"edit" and fix the link yourself. (Or remove the page altogether.)
You can always go to the log in by appending /edit to any URL.

I've also found a related bug with the "brand" link that pointed to
"/" instead of ${application_url}. Fixed here:

Thanks...one last thing....the Kotti pages have not styles.

My configuration is (copied from the Kotti checkout):

[composite:main]

use = egg:Paste#urlmap

/ = mainapp

/cms = kotti

[app:mainapp]

use = egg:pp-demo

pyramid.reload_templates = true

pyramid.debug_authorization = false

pyramid.debug_notfound = false

pyramid.debug_routematch = false

pyramid.default_locale_name = en

pyramid.includes = 

[app:kotti]

use = egg:kotti

sqlalchemy.url = sqlite:///%(here)s/Kotti.db

#mail.default_sender = yourname@yourhost

kotti.configurators = kotti_tinymce.kotti_configure

kotti.site_title = My Kotti site

kotti.secret = qwerty

[filter:fanstatic]

use = egg:fanstatic#fanstatic

#

[pipeline:main]

pipeline =

    fanstatic

    kotti

[server:main]

use = egg:waitress#main

host = 0.0.0.0

port = 6548

The [pipeline:main] does not seem to work with my setup:

LookupError: Ambiguous section names ['composite:main', 'pipeline:main'] for section 'main' (prefixed by 'app' or 'application' or 'composite' or 'composit' or 'pipeline' or 'filter-app') found in config /Users/ajung/sandboxes/zopyx.pyramid.ppdemo/development.ini

What must be fixed here?

Hey Andreas!

From Paster docs you may use ``filter-with`` configuration variable.

So instead of ``pipeline:main`` section you should add the following
option inside ``app:kotti`` section:

filter-with = fanstatic

I've tested it by defining a single kotti app on ``composite:main`` but
I'm not sure if it collides with your app.

Nuno

[Daniel Nouri]

You need to rename the pipeline to something else. 'main' (the main
entry point) is already taken by 'composite'.

Try renaming [app:kotti] to [app:kottiapp], and rename [pipeline:main]
to [pipeline:kotti]. Inside of [pipeline:kotti], refer to 'fanstatic'
and 'kottiapp' (instead of 'kotti').

This should work if everyone plays nice (fanstatic?). The
[composite:main] will point /cms to the pipeline including fanstatic,
instead of merely the Kotti WSGI app.

The styles still do not show up.

Codes base:

https://github.com/zopyx/zopyx.pyramid.ppdemo

WSGI configuration:

https://github.com/zopyx/zopyx.pyramid.ppdemo/blob/master/development.ini

Is there something in the configuration code to be added for Kotti?

https://github.com/zopyx/zopyx.pyramid.ppdemo/blob/master/ppdemo/__init__.py

I promise to document this integration of Kotti with a different application

when I got it working :-)

fair enough. ;-)

I cloned your repo, only added the line mentioned by Nuno before and
have styles working as expected. The complete config now looks like
this (only relevant lines):

--------8<--------schnipp--------8<--------

[composite:main]
use = egg:Paste#urlmap
/ = mainapp

/cms = kottiapp

[app:mainapp]
use = egg:pp-demo

[app:kottiapp]

use = egg:kotti
sqlalchemy.url = sqlite:///%(here)s/Kotti.db

kotti.configurators = kotti_tinymce.kotti_configure
kotti.site_title = My Kotti site
kotti.secret = qwerty

filter-with = fanstatic

[filter:fanstatic]
use = egg:fanstatic#fanstatic

[pipeline:kotti]
pipeline =
fanstatic
kottiapp

[server:main]
use = egg:waitress#main
host = 0.0.0.0
port = 6548

--------8<--------schnapp--------8<--------

Followup: you can even drop the complete [pipeline:kotti] section when
using the filter-with config option.

Andreas

An alternative approach could be to reference the [pipeline:kotti]
section in your urlmap (instead of [app:kottiapp]):

[composite:main]
use = egg:Paste#urlmap
/ = mainapp
/cms = kotti

Sorry for the noise - I should have completed my research before
sending the answer to the list in first place…

True. Or you point [composite:main] to the pipeline ('kotti') and not
to the app ('kottiapp'), which is what I tried to say:

[composite:main]
use = egg:Paste#urlmap
/ = mainapp
/cms = kotti

Important to include fanstatic one way or the other.

That said, filter-with seems more compact. I guess we should change
our standard INIs to use it.
