Improperly configured regex in pinax.wiki.urls?

[jcugley]

django.core.exceptions.ImproperlyConfigured: "^wiki\(?P<slug>[^/]+)/$" is not a valid regular expression: unbalanced parenthesis at position 20

Not sure why it's getting the error, because I'm not smart enough.

Installed exactly as instructed; Am I doing something wrong?

[grahamu]

@jcugley If you provide a bit more of the stack trace perhaps I can help. Searching all Pinax apps on github I do not find a URLpattern anywhere close to yours.

Are you using the latest pinax-wiki, v1.0.1, published to PyPi on Jan 23, 2018? https://pypi.python.org/pypi/pinax-wiki

For sure "^wiki\(?P<slug>[^/]+)/$" is an invalid pattern. Here's an online analysis: https://regexr.com/3kmca.

[jcugley]

@grahamu I think this is the code in question:

This is the file I think the error is coming from: https://github.com/pinax/pinax-wiki/blob/master/pinax/wiki/urls.py

The code is: url(os.path.join(binder.root, r"(?P<slug>[^/]+)/$"), page, {"binder": binder}, name=binder.page_url_name)

It should be the latest since I only installed it today using pinax start --dev wiki mysite

[grahamu]

@jcugley please show me the "wiki" portion of your urls.py. Perhaps you put in a backslash instead of a forward slash after "^wiki" in that pattern? Double-check against https://github.com/pinax/pinax-wiki/blob/master/README.md#installation urlpattern guidance.

[grahamu]

Oh, now I see you edited your comment to add the use of "pinax" CLI tool. You did not add the urls manually.

Yep, you've discovered a bug... not in pinax-wiki but in pinax-starter-projects, "wiki" branch.

[grahamu]

@jcugley thanks for helping debug this... in your urls.py, try

path("", include("pinax.wiki.urls", namespace="pinax_wiki"))

in place of

path("", include("pinax.wiki.urls"))

This is an oversight in pinax-starter-projects. pinax-wiki urls are namespaced, and namespace="pinax_wiki" should be there.

If you verify proper operation with that change I'll publish the fix to pinax-starter-projects. If this doesn't resolve your issue I'll dig in deeper myself.

[jcugley]

@grahamu still getting the same error when I make that change?

my urlpatterns are:

urlpatterns = [ path("", TemplateView.as_view(template_name="homepage.html"), name="home"), path("admin/", admin.site.urls), path("account/", include("account.urls")), path("", include("pinax.wiki.urls", namespace="pinax_wiki")), ]

[grahamu]

@jcugley Please try one more change if you don't mind. It looks like the path() first argument, an empty string, should be "wiki/".

path("wiki/", include("pinax.wiki.urls", namespace="pinax_wiki")),

If this does not fix your issue, please post the full error stack trace as a gist on https://gist.github.com/. Thanks for helping!

[jcugley]

@grahamu that was one of the things I tried as well, however, I'm still getting this error:

[grahamu]

@jcugley What causes the error to appear? Are you trying to see a specific page? Anything to help me isolate the cause would be helpful, thanks.

[jcugley]

@grahamu Can't even run the server, so py manage.py runserver and py manage.py migrate both trigger it.

[grahamu]

Thanks for that feedback @jcugley. I just built a "wikitest" project using pinax-cli as you did. python manage.py migrate worked fine and python manage.py runserver worked fine, albeit with an error when I hit the localhost:8000 page. I found a bunch of errors with templates in the starter project, and an error with pinax-wiki templatetags. It's obvious pinax-wiki and the wiki starter project are not yet up to Django 2.0 standards as these problems are caused by Django deprecations and url namespacing. However, I did not see the same URL issue you reported.

pinax-wiki is not part of the official Pinax 18.01 distribution and pinax-starter-projects doesn't include "wiki" as a supported project, mainly because pinax-wiki has no tests which would catch this sort of problem. That just the nature of immature software, but I apologize for your problems and will do my best to get this working. Thanks for working with me to solve this for you and others.

[grahamu]

@jcugley I've updated and fixed both pinax-wiki and pinax-starter-projects "wiki" branch. Please delete your current mysite project, or at least start again in a new location.

$ pinax start --dev wiki mysite
$ cd mysite
$ pip install -r requirements.txt
$ python manage.py migrate
$ python manage.py runserver

You should see a "Project Wiki" homepage when you browse to localhost:8000.

[jcugley]

@grahamu just did a completely fresh install, now with pinax-wiki-1.0.2 and got exactly the same error... I'm so confused, I'm following all the steps.

[grahamu]

@jcugley are you using virtualenv or pipenv to isolate your development environments?

Perhaps you can join us in Pinax Slack (https://pinax.slack.com) on the #pinax-wiki channel where we can delve into your issues more easily. Ping me there and we'll see what is happening with your setup.

[jcugley]

@grahamu virtualenv with pip, that's not the same as pipenv right?

I think you need to send me a slack invite for that right?

[grahamu]

@jcugley anyone can join Pinax Slack! Hundreds of devs already members. We can talk venv stuff there.

[jcugley]

@grahamu I'm new to slack, how exactly do I join? I'm getting this message when I try to access pinax.slack.com via email login:

"You requested a magic link for logging in to pinax.slack.com. Unfortunately, this email address isn't currently associated with that workspace."

also get this message on the pinax.slack.com page:

"Don't have an account on this workspace yet? Contact the workspace administrator for an invitation"

[grahamu]

@jcugley sorry about my poor earlier directions. Browse to http://slack.pinaxproject.com/ as seen on the bottom of the Pinax project home page. That will get you access to https://pinax.slack.com.
