flask-examples's Introduction

Flask Examples

Example applications for Flask beginners.

Installation

First, you need to clone this repository:

git clone [email protected]:greyli/flask-examples.git

Or:

git clone https://github.com/helloflask/flask-examples.git

Then change into the flask-examples folder:

cd flask-examples

Now, we will need to create a virtual environment and install all the dependencies:

python3 -m venv venv  # on Windows, use "python -m venv venv" instead
. venv/bin/activate   # on Windows, use "venv\Scripts\activate" instead
pip install -r requirements.txt

How to Run a Specific Example Application?

Before run a specific example application, make sure you have activated the virtual enviroment.

For example, if you want to run the Hello application, just execute these commands:

cd hello
flask run

Similarly, you can run HTTP application like this:

cd http
flask run

The applications will always running on http://localhost:5000.

Example Applications Menu

Hello (/hello): Say hello with Flask.
HTTP (/http): HTTP handing in Flask.
Templates (/templates): Templating with Flask and Jinja2.
Form (/form): Form handing with Flask-WTF (WTForms), File upload and integrating with Flask-CKEditor, Flask-Dropzone.
Database (/database): Database with Flask-SQLAlchemy (SQLAlchemy).

flask-examples's Issues

Upgrade to Python 3.8 for hello program

Here's the last part of the stack trace I think time.clock isn't working for Python 3.8

File "c:\users\rskov\appdata\local\programs\python\python38\lib\site-packages\mako\compat.py", line 145, in
time_func = time.clock
AttributeError: module 'time' has no attribute 'clock'

Remove `$ ` from README's commands

Hi,

I just cloned the repository by following the instructions. I am a bit annoyed by the $ character you added at the beginning of each code block. I suggest removing the $ prefix on all lines. This would make it easy to copy-paste, especially for multi-line commands.

EDIT: if the $ is here to express it must be run from a command line, I would suggest writing a small phrase at the beginning, like: "Open your terminal and run the following commands:"

And thanks for the repository, I need to learn about flask, this is a good start to look at your examples.

Error during run with venv (jsmin / use_2to3 is invalid.)

Python 3.10.6

Invalid package

Hi!

requirements.txt lists mako==1.1.13 as a dependency - this version simply doesn't exist on pypi. Works like a charm after changing this to any valid version.
Also, werkzeug is outdated and fails on Python3.9; updating its version to werkzeug==0.15.5 helps.

Cheers,

Can you help me run this project by identifying the part that is wrong?
I tried to set up this example.
