This page is designed to give a brief overview of IVLE, from a users point of
25
view (including administrator and lecturer users). Here we assume that you
26
have :ref:`set up a fresh copy of IVLE <ref-install>` and :ref:`installed the
27
sample data <sample-data>`. This page refers to the sample data specifically.
28
If you are just using an existing installation of IVLE, it might still make a
29
bit of sense, but your mileage may vary.
31
We will take the tour in three stages: first as a student, then as a lecturer,
32
and finally as an administrator.
37
Begin by logging into IVLE as a student (username: 'studenta', password:
43
You will see the IVLE home screen, which displays the subjects you are
44
enrolled in, and your files for each subject. Along the top is the blue bar
45
which is always visible in IVLE. Clicking the IVLE logo always returns you to
48
The user "studenta" is enrolled in several subjects, and has several files
49
already in her Subversion repository, but they aren't immediately accessible.
51
First, click all of the "Checkout" buttons, to check out the Subversion
52
repositories. Now you can explore the sample files, for example, in the
55
Go into the "stuff" directory and left-click the file "hello.py". This will
56
open the build-in text editor, which lets you modify the file. Along the top,
57
there is a button marked "Serve". Clicking this will *run* the Python code as
58
a CGI application -- this should open a new window which reads "Hello,
59
world!". You can also click "Run", which will run the program in the built-in
60
Python console (which pops up from the bottom of the screen). This will be
61
much uglier, printing the CGI output.
63
* "Serve" runs Python programs as CGI applications, showing their web output.
64
* "Run" runs Python programs as command-line applications.
66
Note that you can also use the console at the bottom of the screen as a
67
generic Python console, whenever you wish.
69
You can also serve other files, such as HTML files (try "Welcome to
70
IVLE.html"). This will just present them as normal web pages.
72
Files also have full Subversion histories. If you click on a file in the file
73
view (such as "hello.py"), and go to More Actions -> Subversion -> View Log,
74
you will see the history of a file, and be able to "select" then view a "diff"
75
of the file. If you edit a file, you need to commit it (More Actions ->
76
Subversion -> Commit). If you create a new file (More Actions -> Directory
77
actions -> New file), you need to add it (More Actions -> Subversion -> Add),
83
This student has already completed a project, and is ready to submit it. Go
84
into the Intermediate Ivle -> mywork directory. Select "phase1.html" and
85
choose More Actions -> Publishing -> Submit. This takes you to the Submit
88
Choose to submit to Phase 1, and click Submit Project. You should see a page
89
telling you the submission was successful, with a link to "verify". Verify
90
shows you exactly which files were submitted, and their contents at the time
91
of submission (if the files have changed since then, you'll still see the
92
submitted version). You should verify after each submission -- you can verify
93
any submitted project from the subject page.
95
If you go into the Intermediate Ivle -> group1 directory, you will be able to
96
make a group submission to Phase 2 (which is a group project). Note that the
97
Phase 3 submission has already closed.
98
Also note that the file here ("phase2.html") was edited by studenta and
99
studentb collaboratively, as you can see in the project's revision log.
104
Click on Intermediate Ivle -> Subject Home from the home screen (or, from the
105
IVLE pulldown menu, choose Subjects and select Intermediate Ivle). There is
106
one worksheet, Worksheet Basics. Clicking this takes you to the worksheet,
107
where students are challenged by Python questions.
109
After reading the worksheet, attempt the simple programming question, which is
110
to write a factorial program.
112
A sample solution follows::
124
First, click Submit, and note that the system automatically runs some test
125
cases, all of which fail. Now paste the solution to :func:`fac` (but not
126
:func:`main`). Clicking Submit again shows some test cases pass, but not all.
127
Finally, paste the solution to :func:`main`, and click Submit again. This
128
time, you will pass the test.
130
Note that you can also click "Run", and it will execute your solution in the
131
Python console. This doesn't cost you an "attempt", nor does it run the test
132
cases. It just lets you test it out for yourself before making an official
135
Back on the subject page, you will notice that the exercise appears complete,
136
and you have been awarded some marks.
141
Log into IVLE as a lecturer (username: 'lecturer', password: 'password'). Many
142
of these things are also possible as a tutor (try username: 'tutor', password:
145
Being a lecturer or tutor is a per-subject privilege, so it only applies to
146
certain subjects. All of your special powers are under the subject home for
147
the subjects you are a tutor in. Note that everything a lecturer can do, an
148
admin can also do, for all subjects in the system.
150
Click "Intermediate IVLE - Subject home". From here, you will see largely the
151
same view as a student, but with more buttons. "Change details" allows you to
152
modify the subject properties. "Enrol users" allows you to add existing IVLE
153
users as students or tutors of the subject you are teaching (this is currently
154
an irreversible action).
159
Click "Manage projects" to go to the project management screen. Note that the
160
3 projects are grouped into "Solo projects" (projects submitted by each
161
individual student) and "Group projects". Try adding a new Solo project, by
162
clicking on "Add a new project" within that box. The fields should be fairly
166
You can't currently edit or delete a project after it has been created.
168
Group projects are complicated by what we call "project sets". A "project set"
169
is a set of group projects where the student groups are the same throughout.
170
For instance, you will see Phase 2 and Phase 3 inside the same project set
171
box. This means students will get into groups of 3 to submit Phase 2, and then
172
the same group will submit Phase 3.
174
Clicking "Manage groups" lets you put students into groups for a given project
177
Click "Add a new project set" and enter a group size of 6. Then, create a
178
project in the new set. Each student must get into a new group for each
179
project *set*. Note also that the groups will share a Subversion repository
180
for all projects in a set, but if you create a new set, the students will have
181
to start using a new repository.
183
Usually, the hassle of getting into new groups and creating new repositories
184
means that you will want to create just two project sets for a subject: one
185
for solo projects, and another for group projects.
190
Lecturers and tutors can view any student or group's project submission, using
191
an external Subversion client. As submissions are really just Subversion
192
commits, you can examine a student's work by simply checking out the correct
193
revision of the repository.
195
From the offering page, click "View submissions" under the project of interest.
196
This takes you to a page which lists the latest submissions from every student
197
(presumably you will just see the submission made by "studenta" earlier in
198
this tour). Next to each submission is a command line, beginning with
199
``svn co``. For instance, you might see the line::
201
svn co --username lecturer -r7 http://svn.ivle.localhost/users/studenta/ivle-102/phase1.html
203
Paste this line into a command-line (or, if you use a GUI Subversion client,
204
use the username, revision and URL given). Subversion will likely prompt for a
205
password. For the sample data, this password is "password", but in general, it
206
will **not** be your normal IVLE password. You can learn your Subversion
207
password by opening a Console in IVLE and typing::
210
ivle.config.Config()['user_info']['svn_pass']
212
This will check out the student's work into the current directory, to inspect.
214
You can also try to check out the group submission from Phase 2.
217
It is currently not possible to check out a single file (not a directory)
218
submission using the instructions given. Instead, run ``svn cat``, and
219
redirect the output into a file.
221
Managing worksheets and exercises
222
---------------------------------
224
Return to the subject home page. Click "Manage worksheets". On this page, you
225
will see all of the worksheets for the subject. Here you can edit worksheets,
226
add new ones, and re-order them. You can also edit any worksheet from its own
229
To get an idea of what a worksheet looks like in edit mode, click the edit
230
action (pencil) next to "Worksheet Basics".
232
* The "URL name" is the name of the worksheet as it appears in URLs.
233
* The "Assessable" checkbox will make the exercises in the worksheet count
234
towards each student's worksheet mark, if checked. Uncheck it for
235
informational worksheets.
236
* The "Format" selection controls the format used to write the worksheet in
237
the box below. Leave it on "reStructuredText" unless you have a reason not
240
Now, you can edit the worksheet content in reStructuredText. The existing text
241
briefly explains this format. See `A ReStruecturedText Primer
242
<http://docutils.sourceforge.net/docs/user/rst/quickstart.html>`_ for a full
243
guide. Note that the exercises themselves are not in the worksheet. They are
244
separate resources, which can be shared across subjects. Exercises can be
245
embedded with a line like this::
247
.. exercise:: factorial
249
Click "Manage exercises" to see the exercises (in the sample data, just
250
"factorial"). An exercise is a very complex thing, due to the fact that it
251
runs automated testing on the student code. The details are outside the scope
252
of this tour. Hopefully, you can figure out how they work by examining the
253
existing "factorial" exercise.
255
If you are game enough, create a new worksheet from scratch. If you are
256
*really* game, create a new exercise for your worksheet.
258
An administrator's view
259
=======================
261
Log into IVLE as an admin (username: 'admin', password: 'password').
263
Administrator users in IVLE have significant privileges. Note, however, that
264
for technical reasons, admins cannot read or write other users' files. This
265
requires root access on the machine IVLE is installed on.
267
Firstly, pull down the IVLE menu (top-left). There is an additional item for
268
admins -- the "Users" page. This lists all users with an account in IVLE.
269
Clicking on a username takes you to the user's profile page. Try it with the
272
The profile page is exactly the same as the user himself would see it, but
273
with a few more buttons on the side. "Change password" is the same as the
274
user's own "Change password" page. However, "Reset password" is a special
275
admin page which lets you change a user's password without knowing the old
276
one. "Administer user" also lets you change administrative settings for the
277
user, such as their full name (more formal than display name, which the user
278
themselves can change) and student ID. You can also add/remove admin status
279
for, or disable/enable (i.e., ban from IVLE) any user (except yourself, of
280
course -- that could be bad).
283
Use this with care. Making a user an admin gives them complete control over
284
the system. They could even revoke *your* admin rights!
286
Admin users also enjoy the same privileges as lecturers, for all subjects on
287
the system. In addition, admins can enrol users in a subject as lecturers
288
(this is the only way to become a lecturer). Go to the subject page for
289
"Advanced IVLE" and enrol the user "lecturer" as a Lecturer in the subject.
294
Unfortunately, there are still a few tasks which admins need to do which
295
haven't been implemented in the UI for the IVLE web application. These tasks
296
are available as command-line scripts which can be run by someone with root
297
access on the machine IVLE is installed on. They are gradually being migrated
298
over to proper UI features in IVLE itself.
300
Details on these scripts can be found in :ref:`ref-admin-scripts`.
