redturtle.volto

This is an helper package that setup a RedTurtle's Plone site ready to work with Volto.

python version ci Coverage downloads License

Features

Content-types

  • News Item and Event can only contain Links, Images and Files

Blocks

volto.blocks behavior is enabled by default for these content-types:

  • Document
  • News Item
  • Event

There are also some adapters registered for IBlockSearchableText to index some common blocks.

Links

There is a custom adapter for TextLine field that return the proper widget for remoteUrl.

Custom blocks transformers

There are custom transformers for serializer and deserializer to better manage resolveuids.

If a block refers to some internal content, on deserialization we only store its UID, and in serialization we "expand" informations with the summary-serialized content.

@context-navigation endpoint

plone.restapi's @navigation endpoint always return the navigation tree from the site root.

There is a @context-navigation endpoint that returns the contextual navigation tree:

> curl -i http://localhost:8080/Plone/folder?context-navigation -H 'Accept: application/json'

This is the result:

{
    '@id': 'http://localhost:8080/Plone/folder',
    'items': [
        {'@id': 'http://localhost:8080/Plone/folder/folder-a',
            'description': '',
            'title': 'Folder A'},
        {'@id': 'http://localhost:8080/Plone/folder/folder-b',
            'description': '',
            'title': 'Folder B'},
        {'@id': 'http://localhost:8080/Plone/folder/folder-c',
            'description': '',
            'title': 'Folder C'}
    ]
}

By default only first level is shown. You can pass an expand.navigation.depth parameter to set the depth:

> curl -i http://localhost:8080/Plone/folder?context-navigation?expand.navigation.depth=2 -H 'Accept: application/json'

And this is the result:

{
    '@id': 'http://localhost:8080/Plone/folder',
    'items': [
        {
            '@id': 'http://localhost:8080/Plone/folder/folder-a',
            'description': '',
            'items': [
                {
                    '@id': 'http://localhost:8080/Plone/folder/folder-a/folder-aa',
                    'description': '',
                    'title': 'Folder AA',
                },
                {
                    '@id': 'http://localhost:8080/Plone/folder/folder-a/folder-ab',
                    'description': '',
                    'title': 'Folder AB',
                },
            ],
            'title': 'Folder A',
        },
        {
            '@id': 'http://localhost:8080/Plone/folder/folder-b',
            'description': '',
            'title': 'Folder B',
        },
        {
            '@id': 'http://localhost:8080/Plone/folder/folder-c',
            'description': '',
            'title': 'Folder C',
        },
    ],
}

@site-search endpoint

This endpoint works exactly like @search but take care of types not searchable settings.

@sitemap-settings

Endpoint that returns sitemap settings for anonymous users (that can't access registry entries).

Returns a data structure like this:

{
    'depth': 3,
}

@search endpoint

We customized @search endpoint for that bug: plone/plone.restapi#1066

@querystring-search endpoint customization

If we are searching only for Event types, do a special search using get_events method to search events: that method handle recurrences and avoid wrong results.

Otherwise, perform a default querystring-search.

Disallow bot indexing

There is a custom viewlet that add a <meta> tag in the <head> section to prevent bot indexing.

For reference: https://developers.google.com/search/docs/advanced/crawling/block-indexing?visit_id=637489966041845317-1328107746&rd=1

Restapi Search Limits

Search results length is limited to 500 items by default, but you can change this limit using the environment variable REDTURTLE_VOLTO_MAX_LIMIT_SEARCH

Patches

Products.PortalTransforms

See plone/Products.PortalTransforms#43

There is a monkeypatch to apply that changes.

Events recurrence

There is a monkeypatch for Events recurrences that fix their duration.

If it works well, we can make a pr in p.a.event.

There is another monkeypatch for Events recurrences to change the default behavior of start index serializer. Now it keeps all dates even if the single date is already passed.

Respect locally allowed types on paste

Disallow paste items that are not allowed into destination folder.

DateTime field serializer/deserializer

Customized these adapters to correctly set effective and expires dates.

Without this change, these dates will be stored with UTC hour and not with the current timezone's hour because behavior's setter/getter strip timezone from the value.

With this patch we will send to the setter the date with already localized hour, so even if the setter strip timezone info, we are going to save the correct date.

Default ISerializeToJsonSummary adapter

This is a patch for backward compatibility for old volto templates that need a full image scales object.

Authentication Header

There is a custom event handler for IPubStart that set authorization bearer header from auth_token cookie. For details see the pull-request.

This patch is not enabled by default. You need to set an environment variable to true: PROXY_BEARER_AUTH.

Conditionally search for similar if nonexistent site path passed

plone.app.redirector.FourOhFourView.search_for_similar method patched to return an empty list if the REDTURTLE_VOLTO_ENABLE_SEARCH_FOR_SIMILAR environment variable is set.

New Criteria

There is one new criteria for Collections and Listing blocks that search on exclude_from_nav index.

Caching controlpanel

After installation the caching control panel is populated with custom policies while caching is globally enabled by default. Please, set the caching proxies properly.

@vocabularies permissions

According to new plone.restapi implementation, @vocabularies endpoint will check some permissions to make a vocabulary available or not.

We patched PERMISSIONS variable in __init__ file to allow Keywords vocabulary to be available for anonymous users.

Reference: plone/plone.restapi#1258 (comment)

RamCache in tersecaching

We disabled ramcache for tersecaching (plone.app.caching.terseCaching.plone.content.dynamic.ramCache) because it seems not correctly purged when there are more instances and a content has been modified.

We need to check why it's not purged and fix it.

Template overrides

RSS.pt Template

There is a customization of the Products.CMFPlone.browser.syndication.templates.RSS.pt template to add enclosure tag to feed items. A record has also been added to the registry to be able to set the miniature to be displayed with the RSS item. This record is named redturtle.volto.rss_image_miniature

Fix internal links

There is a view @@fix-links that will check internal links into blocks and fix some links that refs to a staging or local development environment.

Find blocks

There is a view @@find-blocks that will return contents that have at least one block of the given type.

Find broken links

There is a view @@find-broken-links that will return a csv file with a list of contents with broken internal links in blocks.

Stringinterp adapters

There is a new stringinterp adapter that can be used for example in content rules: {volto_url}

This adapter will remove "/api" from the content's absolute_url.

Sitemap.xml.gz view customization

There is a custom view sitemap.xml.gz that will return a sitemap.xml.gz file.

This is a copy of the original view from plone.app.layout.sitemap.sitemap

The only difference is that:

  • we restrict level of depth to plone.sitemap_depth registry setting (default 3)
  • we add content modified in the last week

With Volto, for serve this file, we need to add a line like this in apache config:

RewriteRule ^/+(sitemap.xml.gz) http://127.0.0.1:8080/VirtualHostBase/https/%{SERVER_NAME}:443/Plone/VirtualHostRoot/$1 [L,P]
