STUDENT DIRECTORY

This is a project I worked through over the first two weeks at Makers Academy. In its various forms, it allows you to enter and view a list of students enrolled on the course. Because I was bad at version control, each new chunk has its own file. The most important file is 'directory-week-2.rb', as it has all the main functionality, but if you want to know more about the other files, well, here's what they can do and how.

directory.rb

This was the introduction to the project.

$ ruby directory.rb

It asks you to enter all the names, one by one, before letting you end by entering a blank name. It then prints out the names of the students. Simple.

Please enter the names of the students

Alex (january cohort)
Overall, we have 6 great students

directory-challenges.rb

Once we'd completed the main functionality, we were then set additional challenges. Some of these were slightly contradictory, which is why there's so much text commented out (again, I promise I know better now). They included not using puts, implementing various filters, adding additional information, grouping by cohort and implementing your own version of chomp. Many of these were completed pairing with @plawtr. In its current form, it simply groups all the students by cohort and works a little as follows:

$ ruby directory-challenges.rb

First, it'll present a menu, asking you whether you want to enter students, print students or exit. Press '1', '2' or '9' to get the corresponding option. If you hit '1' you'll be asked to enter a student's name as before, but you'll also get various other fields to fill in, too. Again, submit an empty name to end the process. When you subsequently hit '2', you'll see all the names you entered, grouped by cohort. '9' will exit everything.

I was working on a way to give options to activate various filters in the menu (all the actual functionality's there), but apparently never got round to finishing it.

typos.rb

This was a challenge to correct typos in a document without consulting Google. Seems to be working.

directory-week-2.rb

OK, now, this version has everything working properly. You can select various filtering options, the code's much nicer and you can also save to and load from a students.csv file.

$ ruby directory-challenges.rb

So, we start with a new menu. '1' works much as before. '2' shows all the students. '3' shows all the students grouped by cohort, as was the default in the previous version. '4' will ask you for a letter to filter by, before showing only the students whose names begin with that letter. '5' saves the current list of students to (and creates if necessary, I think) a file named 'students.csv'. '6' will load a list of students from that file if it exists. '9' will exit, as usual.

1. Input the students
2. Show the students
3. Show the students listed by cohort
4. Show students filtered by the first letter of their name
5. Save the list to students.csv
6. Load the list from students.csv
9. Exit

Which should leave students.csv looking like:

I also worked on a version of this with @CrowdHailer (based on his first week code), but I think all the main functionality we added together was later incorporated here. Still, that can be found (here)[https://github.com/NotTheUsual/Student-Directory-1]
