Page Management

Page Management

You need the page’s access token to manage your page.
Your (an user’s) access token doesn’t work here.

See this official document for more details.

Settings

# Get an access token of page.
page = FbGraph::Page.new('FbGraph').fetch(
  :access_token => USER_ACCESS_TOKEN,
  :fields => :access_token
)

# List of all *enabled* settings
page.settings

# Ask each setting is enabled or disabled
page.users_can_post?        # => boolean
page.users_can_post_photos? # => boolean
page.users_can_tag_photos?  # => boolean
page.users_can_post_videos? # => boolean

# Enable each setting
page.users_can_post!        # => boolean
page.users_can_post_photos! # => boolean
page.users_can_tag_photos!  # => boolean
page.users_can_post_videos! # => boolean

# Disable each setting
page.users_cannot_post!        # => boolean
page.users_cannot_post_photos! # => boolean
page.users_cannot_tag_photos!  # => boolean
page.users_cannot_post_videos! # => boolean

# You can enable/disable settings like this too.
page.enable!(:users_can_tag_photos)
page.disable!(:users_can_tag_photos)

Tabs

# Get an access token of page
page = FbGraph::Page.new('FbGraph').fetch(
  :access_token => USER_ACCESS_TOKEN,
  :fields => :access_token
)

# List of all installed tabs (includes wall & info tabs)
tabs = page.tabs

# Install a tab
tab = page.tab!(:app_id => APP_ID_YOU_WANT_TO_INSTALL)

# Update an existing tab
tab.update(
  :custom_name => 'Custom Name',
  :position => 1
)

# Uninstall a tab
tab.destroy

Publish / Schedule Page Posts

page = FbGraph::Page.new('FbGraph').fetch(
  :access_token => ACCESS_TOKEN,
  :fields => :access_token
)

posts = page.promotable_posts

posts.publishable? # => boolean
posts.schedulable? # => boolean
posts.scheduled?   # => boolean

# Schedule (or Re-schedule) Post
posts.first.schedule!(7.day.from_now) # => true or raise exception

# Cancel Current Post Schedule
posts.first.unschedule! # => true or raise exception

# Publish Immediately
posts.first.publish! # => true or raise exception

NOTE:
Unpublishing posts is not allowed.
This means that once you published a page post accidentally, you have to ask the page owner to unpublish it manually.
And of course, you can’t schedule already published posts.
