A linked view of the test database is placed at the bottom of this page. A link to the method reference is provided at the end of the description.

1. Preparation (instance → self.instance → NotionCache, create_client → create_client(notion_token, wait: 0.1))

   require "notion_ruby_mapping"
   
   include NotionRubyMapping
   
   token = ENV["NOTION_API_TOKEN"]
   database_id = "c37a2c66e3aa4a0da44773de3b80c253" # ENV["DATABASE_ID"]
   NotionCache.instance.create_client token
   
   

2. Retrieve a database (find → self.find(id, dry_run: false))

   db = Database.find database_id
   => 
   #<NotionRubyMapping::Database:0x0000000104f6cb10
   

3. Obtain properties (properties → properties → PropertyCache)

   title_property = db.properties["Title"]
   => #<NotionRubyMapping::TitleProperty:0x0000000106f7d288 ...
   
   select_property = db.properties["SelectTitle"]
   => 
   #<NotionRubyMapping::SelectProperty:0x00000001055b3320 ...
   

4. Query database without filter (query_database → query_database(query = nil, dry_run: false) → List)

   all_pages = db.query_database
   => 
   #<NotionRubyMapping::List:0x0000000106f9c890 ...
   

5. Count all_pages (Enumerable → each { |item| ... } → self each → Enumerator)

   all_pages.count
   => 6
   

6. Obtain all page title (Enumerable → each { |item| ... } → self each → Enumerator, title → title → String)

   all_pages.map(&:title)
   => ["", "JKL", "MNO", "DEF", "GHI", "ABC"]
   

7. Query database with filter (query_database → query_database(query = nil, dry_run: false) → List, filter_equals → , ascending → ascending(property) )

   select3_pages = db.query_database select_property.filter_equals("Select 3").ascending(title_property)
   => 
   #<NotionRubyMapping::List:0x000000010889ef28 ...
   

8. Count select3_pages (Enumerable → each { |item| ... } → self each → Enumerator)

   select3_pages.count
   => 2
   

9. Obtain select3_pages title (Enumerable → each { |item| ... } → self each → Enumerator, title → title → String)

   select3_pages.map(&:title)
   => ["ABC", "MNO"]
   

10. Obtain the first page (Enumerable → each { |item| ... } → self each → Enumerator)

    abc_page = select3_pages.first
    => 
    #<NotionRubyMapping::Page:0x0000000108494860
    

11. Obtain the multi_select_names of the page (properties → properties → PropertyCache, multi_select_names → multi_select_names → Array)

    abc_page.properties["MultiSelectTitle"].multi_select_names
