Modules[ویرایش]

خطای اسکریپتی: پودمان «convert/tester» وجود ندارد.

پودمان:Team appearances list is invoked by {{Team appearances list}} to display a ویکی‌پدیا:شیوه‌نامه/دسترسی‌پذیری showing the years a specified team participated in a specified competition. Each year of attendance is wikilinked to a corresponding article, while years the team did not compete (absences) are shown as disabled.

The names of the competition and team must be specified. Optionally, information for a competition can be defined in پودمان:Team appearances list/data, and team information can be included:

  • begin_year – The first year to be shown.
  • end_year – The last year to be shown.
  • Years the team did not attend the competition.

If begin_year or end_year are defined for a team, they set default values that can be overridden with parameters in the template.

If a team is defined for a particular competition, any absent years in the templace call are ignored (instead, the absences defined in the data module are used).

پودمان:Team appearances list/show is used for testing. It shows the results for all competition/team pairs defined in the data module. The results are displayed at Module talk:Team appearances list/show.

Changes should be performed in the sandbox modules, using the following for testing:

  • {{Team appearances list/sandbox}} – Uses the sandbox main and data modules.
  • Module talk:Team appearances list/show – Results for all competition/team pairs defined in the sandbox data module.

Errors[ویرایش]

Parameters provided by the template are validated using the following rules.

Always:
    competition   required : non-empty string
    team          required : non-empty string

If competition is defined in data module:
    begin_year    optional : number from 1800 to 2100 inclusive
    end_year      optional : as above (and end_year >= begin_year)
else:
    begin_year    required : as above
    end_year      optional : as above
    interval      required : number from 1 to 30 inclusive

An invalid parameter causes an error to be displayed and places the page in the hidden category رده:صفحه‌های دارای خطاهای اسکریپتی.
