Overview

Example Usage

  1. Require the lib: require 'fotolia'

  2. Get a new instance of the base class: fotolia = Fotolia::Base.new :api_key => 'AAAAA'

    Note: You may also use the shortcut Fotolia.new.

  3. Search for some media: search_results = fotolia.search :words => 'nitpick'

    search_result now contains an array of Fotolia media containing the word 'nitpick' somewhere. Note that the array won't have more than 50 items per default as Fotolia limits the number of media returned (the max is 64). However, the array is extended in some ways as it is not a plain Array object, but a SearchResultSet instead. So you can call search_results.total to get the total number of all results or search_results.next_page to get the next set of results. See SearchResultSet for more information.

    Each medium is represented by the class Fotolia::Medium, so check its documentation for further info.

  4. Get all representative categories in root level (Fotolia has two types of categories, representative and conceptual ones. Each root category may have children and grand-children): r_cats = fotolia.representative_categories

    This gives you an array of all root-level representative categories. You may get the children of the first cat by calling r_cats.first.children

    You can fetch a category's media by calling r_cats.first.media Note that this method takes the same options hash as parameter as Base#search.

  5. You may change the language used in all returns of Fotolia's API. Default is :en_us. Also available are :en_uk, :fr, :de, :es, :it, :pt_pt, :pt_br, :jp and :pl. To use one of them, pass the initializer of Base an Fotolia::Language instance:

    fotolia = Fotolia.new :api_key => 'A...', :language => Fotolia::Language.new(:de)

    Category names, tags and some other items will be returned in German now. If it's not translated, it's Fotolia's fault, not this gem's ;-)

  6. Get a Fotolia medium by its ID

    You may use the :media_id option of Base#search, but calling

    medium = Fotolia::Medium.new fotolia, :id => 12334567

    is just more intuitive. The class will try to fetch all missing data from Fotolia. You should catch CommunicationErrors when using any medium object generated this way as an of those will be raised if the given media id is unknown to Fotolia.

  7. Login a user and get its galleries and add a medium to the first.

fotolia.login 'username', 'password' galleries = fotolia.logged_in_user.galleries medium = Fotolia::Medium.new fotolia, :id => 12345678 medium.add_to_user_gallery galleries.first fotolia.logout
