Have you considered using a database activity with require approval enabled and never actually approving any entry? This should have the same effect you're trying to produce, namely, each student would be able to see only his/her entries and the teacher would see them all. I haven't tried it myself yet so if you try it please let me know if it works.

Why don't you simply upload all files to the course Files and then csv the file names to the database (into a text field) and set the view templates to display the links?

I may have an indirect solution for that.

Suppose you have four groups. You create four quiz assignments, one for each group. The quiz should be set up such that one needs only to answer a simple question to get 100%. All students should take the quiz of their group and answer correctly.

In the gradebook you hide these four quiz items and add a grade item for the assignment. You set the formula of the grade item to

=||assignment-group1||*0.00+||assignment-group2||*0.00+||assignment-group3||*0.00+||assignment-group4||*0.00

Then you mark the assignments. Now suppose group 1 scored 75%, group 2 - 84%, group 3 - 100% and group 4 - 92%. You go back to the grade item and update the formula to

=||assignment-group1||*0.75+||assignment-group2||*0.84+||assignment-group3||*1.00+||assignment-group4||*0.92

This should assign each student the grade his/her group got for the group assignment.

Hope this works for you.

For preventing editing you you can remove the ##edit## link from the list and single templates (although editing may still be accessed via the url if the user figures it out).

For allowing only one post you can set the 'Maximum entries' field in the database settings to 1.

Hope this helps

You should enable the RSS for the database in the database settings by selecting a number of RSS articles to show (up to 50 without hacking the code) and then you should be able to see in the database page an icon which you can click to open the feed in your browser.
