  • grid.html
  • parameters
    • categories : categories_list = __get_categories(user) code:

    ## return the category list with the tasks info
    def __get_categories(user):
      categories = Category.objects.all() 
      for cat in categories:
        task_list = []
        for task in cat.activitybase_set.all():   
          task.is_unlock = is_unlock(user, task)
          task.is_pau = is_pau(user, task)
          task_list.append(task)
        cat.task_list = task_list
    return categories

• Task page
  • task.html
  • parameters:

    "task"        : activity object
    "type"        : is event or not
    "pau"         : is pau
    "approved"    : is approved
    "form"        : input form for the task
    "question"    : activity question if any
    "member_all"  : number of person completed the task
    "member_floor": number of person of the floor completed the task

• Events
  • events.html
  • parameters:
    • events = get_available_events(user)

def get_available_events(user):
  """Retrieves only the events that a user can participate in."""
  events = Activity.objects.exclude(
    activitymember__user=user,
  ).filter(
    type='event',
    pub_date__lte=datetime.date.today(),
    expire_date__gte=datetime.date.today(),
  ).order_by("priority", "title")
  return events # Filters out inactive activities.

• Unlocking (in init.py)

def is_unlock(user, task):
  """determine the unlock status of a task by dependency expression"""
  expr = task.depends_on
  if expr == None or expr == "":
    return False
  
  expr = expr.replace("completedAllOf(", "completedAllOf(user,")
  expr = expr.replace("completedSomeOf(", "completedSomeOf(user,")
  expr = expr.replace("completed(", "completed(user,")
  expr = expr.replace("afterPublished(", "afterPublished('"+task.name+"'")

  allow_dict = {'completedAllOf':completedAllOf,
                'completedSomeOf':completedSomeOf, 
                'completed':completed,
                'afterPublished':afterPublished,
                'True':True,
                'False':False,
                'user':user,
               }

  return eval(expr, {"__builtins__":None}, allow_dict)
