This link currently does not exist. Should we add it per project?
https://github.com/kurniawano/d2w_mini_projects/blob/master/mp_calc/DeployEB.md

Or have a folder for common md documents?

Some students cannot get the correct link (not recursive problem) when running flask run on Vocareum, they are not redirected to the right page and results in 404. Only some students faced this problem, TAs cannot find a solution or pinpoint the exact issue, need to investigate

Socket.io on client-side code polls 'https://proxy.vocareum.com/socket.io/?EIO=3&transport=polling&t={ data }' instead of 'https://proxy.vocareum.com/hostip/{ voc_ip }:{ voc_port }/vocproxy/{ voc_token }/socket.io/?EIO=3&transport=polling&t={ data }', hence fails to form connection to server when running through Vocareum proxy.

I realised my tests didn't pass but I was unfamiliar with jupyter notebook ><
In[*] <--- means the code is still running - I thought since i clicked through, that means the code passed already

That being said I think it can be very misleading

expr2 = EvaluateExpression("(1+2 *4-  3)* (7/5 * 6)")
assert expr2.evaluate() == 36 #3rd test

Based on the instructions is possible to iterate through self.expr directly which will likely cause issues. It will look like when you finally pass the first 2 cases, then 3rd case which causes the [*] may appear like you also passed

expression = self.insert_space()
tokens = expression.split()

I propose that we could mention the need to do this (below) somewhere in the instructions! And perhaps just a note to students unfamiliar to jupyter like me that [*] doesn't mean pass ><

before cloning, remove the cd Download command as it does not apply in vocareum. Remove the other references to Downloads folder.

I’ve encountered this bug after copying in the new code for init, forms, middleware, models and routes .py files.

Specifically when I logout, the URL becomes “https://vocproxy-1-48.us-west-2.vocareum.com/proxy/5000/proxy/5000/login?next=%2Fproxy%2F5000%2Findex”, containing 2 “/proxy/5000”s rather than 1. As a result, when I log in again it gives the error message:

Not Found
The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.

When I remove the second “/proxy/5000”, it works and I am logged in.

How can I fix this issue? Thanks.

The Readme.md and the https://data-driven-world.github.io/2023/projects/sorting-app describe Pipfile.lock present in mp_sort after cloning but there is no such file in the repo.

Unix/MacOS

cd d2w_mini_projects/mp_sort
ls

The last command should output the following:

Readme.md       
application.py
Pipfile
**Pipfile.lock**
app

This is done locally on MacBook Pro with Google chrome.

mp_sort

Assignment For Exercise 2.

Search the internet to find out how to create a Text Input field and enter the code in the line indicated. Replace that line with the correct tag and code for Text Input. Name the text input numbers. You may want to also specify some default values to appear in the text input.

MP 2 does not modify clientside.py so we can just give the javascript file.

Hi prof,

Noticed that for all the mini projects, the first instruction is always to clone the repo using

$ git clone https://github.com/kurniawano/d2w_mini_projects.git

However, it seems that the repo on your account is not as updated as the one at https://github.com/Data-Driven-World/d2w_mini_projects.git.

Should the repo to clone be the one in Data-Driven-World instead?

Line 50 and line 54 in routes.py of mp_calc can be reduced to a single line.

as follows:

mini-project 1, windows users and mac users (edited), attention:
if pipenv install doesn't work, try python -m pipenv install,
similarly for pipenv shell, try python -m pipenv shell

at one point you are told to type this command, note that this is only if/when you are trying out the process in Vocareum, not on Windows/Mac
export PATH='/voc/work/.local/bin':$PATH

Should we include a section that includes stuff like

1. ModuleNotFoundError: No module named 'flask_bootstrap'? Or just can't run flask/use transcrypt?

• Are you in your virtualenv ? source virtenv/bin/activate

2. The app doesn't change even though I make changes to the code?!?

• If you made changes to files in app/static
  Did you run python -m transcrypt -b target.py <-- target being file you are transpiling
• What you want is hot-reloading
  You can run export FLASK_ENV=development before flask run
  or flask run --reload --debugger

Typo under https://github.com/Data-Driven-World/d2w_mini_projects/blob/master/mp_calc/Readme.md#brief-overview-of-flask-project-structure

Quoted:

• In the last line, render_template('users.html', title='Users', users=usernames), we pass the variable username to be used in the users.html using some jinja templating under the name users.

Correction:

Variable name should be usernames instead of username

At Exercise 1:

The first line {% extends "base.html" %} inherits the base.html for some of the common elements such as the navigation bar, importing certain scripts, and CSS files. The javascript which we will transalte translate from the file serverlibrary.py is imported in the last few lines of base.html.

Allow different ordering when sorting based on the second element in the jupyter notebook. See #65.
