* Penciling in a Default Spaces section
This delivers two primary things:
1. Extracting shared policy examples
2. Providing a functioning skeleton for toggling on the
"limit_post_creation_to_admins" feature.
Important is that once merged, it would be possible for this code to
"leak" out. But how that leaks out is also how you can test that the
feature works.
First, to orient, there is a constraint for a new route. That
constraint checks if the feature flag exists (e.g. has been explicitly
enabled or explicitly disabled). In other words, at this point, you
can't accidentally enable the feature via the UI. But once you have
enabled the feature, you can then toggle the feature on and off.
So, to test this in the browser:
1. Pull down this branch
2. Run `rails runner "FeatureFlag.disable(:limit_post_creation_to_admins)"`
3. Startup your the web server.
4. Login as an administrator
5. Goto /admin/content_manager/spaces
a. Bask in the glory of a plain HTML form
6. With another browser, login as another non-admin user
7. Go to /settings/extensions, you should see a section Publishing from RSS.
8. Now with the admin's session, update the form to turn on
"limit_post_creation_to_admins"
9. Back to the non-admin browser, refresh /settings/extensions, you
should no longer see the section Publishing from RSS.
Note: I have not included an admin menu item as that is related to and
dependent on some refactors I'm working on (see forem/forem#16888 and
forem/forem#16847). So a bit of "security through obsurity"
Note: In the future, once we resolveforem/forem#16490, we'll start
toggling the "Create a Post" button.
Note: I am not including Cypress tests nor request tests for this
feature because the implementation details related to the testing via
that approach are a little too volitale.
