Package struct

Concepts

Database app_label

If OPENGRAPH_META_APP_LABEL would be found in django.conf.settings it will be used as prefix each db model name, exclude TwitterCards models, which use TWITTER_CARD_META_APP_LABEL

Universal page attributes:

Class methods:
  • og_name(cls)
    • Returns the OpenGraph scope name, which was set at the class initialization
  • og_properties(cls)
    • Returns the OpenGraph scope properties, which was set at the class initialization
Methods:
  • og_metadata(self)
    • Returns the Generator[Tuple[str, str]] with collected meta information. Empty fields will not be included to that selection.
  • og_name(self)
    • Return Generator[str] (wrapped metadata), which present as Iterable HTML DOM based meta tags

Universal subpage attributes

Class OGSubpage (source) is a parent of each page class, excluding the OGWebPage. It determines ForeignKey field page, which links to OGWebPage object associated for present data. It proxied two properties of the page

  • url
  • title

, to the main OGSubpage scope

Universal music attributes

Arguments *args and **kwargs will be transfer to selected object instance constructor without any modification.

Class methods:
Database fields:
  • ForeignKey audio: The audio file (source) associated with the page
    • URLField url: Contains video's url. (og:audio)
    • CharField type: Contains MIME type of the video. (og:audio:type)
    • URLField secure_url: Contains video's alternate url to use if the webpage requires HTTPS. (og:audio:secure_url)

Product classification

Model OGProductPage uses predefined values of the Google's taxonomy classification. It is a big document (~5.5k lines) with the deep enclosing and inheritance of the categories. So, that module support each element of the taxonomy, but not used all of them by default. Project setting's variable OPENGRAPH_PRODUCT_TAXONOMY_DEPTH defines level of the enclosing, which will be presented by root class Categories (source) (2 by default). It means, that second enclosing of the category (for example: OGProductPage.Categories.AnimalsAndPetSupplies.LiveAnimals) cannot contain any subcategory and would be final. If OPENGRAPH_PRODUCT_TAXONOMY_DEPTH is equal 0, it is means, that there is no any enclosing limits.

Note: List of the categories, which are contained into the current Taxonomy instance (source) can be got by the method of that instance categories(self)

You can use the setting's variable OPENGRAPH_PRODUCT_TAXONOMY_BASE for the defining the root category of your current project. For example, if your project is used for the cloth sale, it can be sensible to set the OPENGRAPH_PRODUCT_TAXONOMY_BASE = 'ApparelAndAccessories.Clothing'. It excludes the non-contextual values from the choices of OGProductPage.category.

Setting's variable OPENGRAPH_PRODUCT_TAXONOMY_FILEPATH can be used for the linking of custom taxonomy file, instead of builtin taxonomy.json, for the categories tree build

Boolean setting's variable OPENGRAPH_PRODUCT_TAXONOMY_FULLNAME (False by default) determines the name of category entity, which would be present at the choices property. fullname reflects the tree, in contrast of the name

Currency code

Model OGPrice (source) uses a part of logic the Product classification in the currency defines. It has support two variables: OPENGRAPH_PRODUCT_CURRENCY_FULLNAME and OPENGRAPH_PRODUCT_CURRENCY_FILEPATH with same logic. So if you want to limit list of currencies in your project, creation project-specific currency.json is a simple way to do it
