Sheet

The first time a Sheet is saved in a Class, the corresponding instance of the class is then link to the Sheet through the .wclass attribute. This allow to use some methods such as delete() or save() without any argument.
The instance of Class is also link to a Sheet obtained through Class.getitem() or Sheet.get().

Instantiation

To get a Sheet instance, you have two possibility. You can either create a new instance, or get one from the WIMS server.

To create a new instance :

from wimsapi import Sheet

sheet = Sheet("Title", "Description")

Sheet can also take a lot of optionnal argument:

Sheet(title, description, expiration=None, sheetmode=0, weight=1, formula=2, indicator=1, contents="")

Where:

  • title - (str) name of the sheet (defaults to "sheet n#")
  • description - (str) description of the sheet (defaults to "sheet n#")
  • expiration - (str) expiration date (yyyymmdd) defaults to one year later
  • sheetmode - (str) the mode of the sheet:
    • 0 : pending (default)
    • 1 : active
    • 2 : expired
    • 3 : expired + hidden
  • weight - (int) weight of the sheet in the class score (default to 1), use 0 if you want this sheet's score to be ignored.
  • formula - (str) How the score is calculated for this sheet (0 to 6, default to 2)
    • 0 : Very lenient: maximum between percentage and quality.
    • 1 : Quality is not taken into account. You get maximum of grade once all the required work is done.
    • 2 : Quality has only slight effect over the grade.
    • 3 : More effect of quality.
    • 4 : To have a grade of 10, you must gather all required points (100%) without making any error (quality=10).
    • 5 : Unfinished work is over-punished.
    • 6 : Any mistake is over-punished.
  • indicator - (str) what indicator will be used in the score formula (0 to 2, default to 1)
  • contents - (str) the contents for the multi-line file to be created. The semicolons (;) in this parameter will be interpreted as new lines. Equal characters (=) must be replaced by the character AT (@). There is no check made, so the integrity of the contents is up to you only! (defaults to "")"""

To get an instance from the WIMS server, you can use either of the following class method :

Sheet.get(wclass, qsheet)

Where :

  • wclass is an instance of Class which the Sheet belong to.
  • Sheet is the identifier corresponding to the sheet.

or

c.getitem(qsheet, Sheet)

Where :

  • c is an instance of Class which the Sheet belong to.
  • qsheet is the identifier corresponding to the sheet.
  • Sheet the Sheet class.

Saving

Any changes made to a Sheet instance can be reflected on the WIMS server with the method save() :

from wimsapi import Class, Sheet
c = Class.get("https://wims.unice.fr/wims/wims.cgi", "myself", "toto", 9999, "myclass")
s = Sheet.get(c, "qsheet")
s.firstname = "Newname"
s.save()

If the Sheet has been instantiated through its constructor, and not with one of the get method, and has not been saved yet, you will need to provide a Class which had already been saved on the server.

c = Class.get("https://wims.unice.fr/wims/wims.cgi", "myself", "toto", 9999, "myclass")
s = Sheet("qsheet", "lastname", "firstname", "password", "mail@mail.com")
s.save(c)

To add an Sheet to a Class, you can also use c.additem(sheet).

c = Class.get("https://wims.unice.fr/wims/wims.cgi", "myself", "toto", 9999, "myclass")
s = Sheet("qsheet", "lastname", "firstname", "password", "mail@mail.com")
c.additem(s)

In fact, c.additem(sheet) will call sheet.save(c), therefore if a same sheet is added to multiple classes through s.save(c) or c.additem(s), future call to s.save() will only save changed on the last Class the Sheet has been saved to.

c = Class.get("https://wims.unice.fr/wims/wims.cgi", "myself", "toto", 9999, "myclass")
c2 = Class.get("https://wims.unice.fr/wims/wims.cgi", "myself", "toto", 8888, "myclass")
s = Sheet("qsheet", "lastname", "firstname", "password", "mail@mail.com")

c.additem(s)
s.save(c2)
s.firstname = "Newname"
s.save()  # Only save changes on c2

Reloading an instance

To reflect server-side changes on an instance of Sheet, use refresh() :

s.title = "Old"
c.save(s)

s2 = c.getitem(s.qsheet, Sheet)

s2.title = "New"
s2.save()

s.institution # "Old"
s.refresh()
s.institution # "New"

Deleting

To delete an already saved Sheet s from a Class c, you have a lot possibility:

  • s.delete()
  • Sheet.delete(c, s)
  • Sheet.delete(c, "qsheet") where "qsheet" == s.qsheet
  • c.delitem(s)
  • c.delitem("qsheet", Sheet) where "qsheet" == s.qsheet

Check if a sheet exists in a WIMS class

To check whether Sheet u is in a Class c, you have once again a lot of possibility:

  • Sheet.check(c, s)
  • Sheet.check(c, "qsheet") where "qsheet" == s.qsheet
  • c.checkitem(s)
  • c.checkitem("qsheet", Sheet) where "qsheet" == s.qsheet
  • s in c

All of these methods return True if the sheet exists in the class, False otherwise.

More Data

Once the Sheet has been saved you can acceed the additionnal fields infos and wclass which is the instance of Class this sheet is saved on:

c = Class.get("https://wims.unice.fr/wims/wims.cgi", "myself", "toto", 9999, "myclass")
s = Sheet("Title", "Description")
c.additem(s)

s.wclass == c # True

c.infos
