Flask Routing and Views Lab

Learning Goals

Build and run a Flask application on your computer.
Manipulate and test the structure of a request object.

Key Vocab

Web Framework: software that is designed to support the development of web applications. Web frameworks provide built-in tools for generating web servers, turning Python objects into HTML, and more.
Extension: a package or module that adds functionality to a Flask application that it does not have by default.
Request: an attempt by one machine to contact another over the internet.
Client: an application or machine that accesses services being provided by a server through the internet.
Web Server: a combination of software and hardware that uses Hypertext Transfer Protocol (HTTP) and other protocols to respond to requests made over the internet.
Web Server Gateway Interface (WSGI): an interface between web servers and applications.
Template Engine: software that takes in strings with tokenized values, replacing the tokens with their values as output in a web browser.

Instructions

This is a test-driven lab. Run pipenv install to create your virtual environment and pipenv shell to enter the virtual environment. Then enter the server/ directory and run pytest -x to run your tests. Use these instructions and pytest's error messages to complete your work in the server/ directory. If you prefer working in a Flask environment to running your application as a script, remember to configure it with the following commands from the server/ directory:

$ export FLASK_APP=app.py
$ export FLASK_RUN_PORT=5555

Instructions begin here:

Design a Flask application that carries out basic Python functions using routing and views.
Your index() view should be routed to at the base URL with /. It should Contain an h1 element that contains the title of this application, "Python Operations with Flask Routing and Views".
A print_string view should take one parameter, a string. It should print the string in the console and display it in the web browser. Its URL should be of the format /print/parameter.
A count() view should take one parameter, an integer. It should display all numbers in the range of that parameter on separate lines. Its URL should be of the format /count/parameter.
A math() view should take three parameters: num1, operation, and num2. It must perform the appropriate operation on the two numbers in the order that they are presented. The included operations should be: +, -, *, div (/ would change the URL path), and %. Its URL should be of the format /math/<num1>/<operation>/<num2>.

Once all of your tests are passing, commit and push your work using git to submit.

python-p4-routing-and-views-lab's Issues

\n not actually working with Flask

Canvas Link

https://learning.flatironschool.com/courses/6201/assignments/234459?module_item_id=549423

Concern

The test for count() gives us an AssertionError unless we use a for loop and add \n to the end of each iteration, but Flask is still displaying everything on a single line when \n is used.
I had to look it up, but using
instead of \n does place each element on a new line, though it won't pass the test.

Additional Context

No response

Suggested Changes

Either explain why we would use newline with \n despite it not actually working when we go to the route, or use
in the test.

math() not working as described

Canvas Link

https://learning.flatironschool.com/courses/6201/assignments/234459?module_item_id=549423

Concern

The instructions tell us that:

Its URL should be of the format /math/<num1><operation><num2>.

It isn't possible for this to work, since anything we enter after "/math/" will be read as only a single input. It will need to be

/math/<num1>/<operation>/<num2>

Since we've just started this phase and have very little idea of why that is the case, it makes it really difficult to understand why the tests aren't passing and why we're getting errors.

Additional Context

No response

Suggested Changes

Correct it to say that the URL should be of the format /math/<num1>/<operation>/<num2>

Clarification on print_string() printout

Canvas Link

https://learning.flatironschool.com/courses/6259/assignments/233457?module_item_id=547379

Concern

README Line 52: It may be helpful to specify that the console printout that is part of the functionality we’re adding for print_string() will appear within the terminal that’s running the server when the server restarts.

I was looking for it in the browser console…

Formatting error

Canvas Link

https://learning.flatironschool.com/courses/6209/assignments/234544?module_item_id=549606

Concern

One of the view functions has an incorrect instruction. Here is the original instruction:

"A math() view should take three parameters: num1, operation, and num2. It must perform the appropriate operation on the two numbers in the order that they are presented. The included operations should be: +, -, *, div (/ would change the URL path), and %. Its URL should be of the format /math/num1 operation num2"

Additional Context

No response

Suggested Changes

URL formatting is incorrect based on the tests provided. It should instead be:

/math/num1/operation/num>

The backslashes are missing.

Requested Formatting Difference Between Tests and Deliverables

Canvas Link

https://learning.flatironschool.com/courses/6560/assignments/243002?module_item_id=571674

Concern

In display of the README at the link, it is not correctly displaying the requested format in the markdown version of itself. In the raw README on line 62 and in the tests at lines 48-51 it's asking for the route to include slashes between the parameters. The site itself is displaying that incorrectly.

Additional Context

Example code does not work for two digit math operations

Canvas Link

https://learning.flatironschool.com/courses/6267/assignments/236255?module_item_id=554210

Concern

/math/ will interpret num2 to only be last digit, so then operation would be e.g.
20div10 : num1:20, operation:div1, num2:0

fix: use
/math/
for the route

Additional Context

No response

Suggested Changes

fix: use
/math/
for the route
