Building my first web app (Part Three)

Building my first web app – part three

Okay, I haven’t done any work on this since spending most of Sunday working through a strange bug that caused a few issues. Mostly, I had failed to do two things:

1. Set up the database correctly – I had to run the create app function. 
2. I had called the parameters in some of the functions the wrong names (actually, I had got them around the wrong way)

Building my first web app – part four

So, I have now successfully created the basics of my web app. It has a facility for log in, it restricts web pages to only people who are logged in, and I have added a shopping list function. The next step is to add a to do list function. Again, I would like, at some point in the future, to be able to have different categories, and perhaps even a sortable or searchable function, but that’s beyond the scope of this app. In the meantime, the time has come to add the to do list function. Here’s what I need to do:

1. Create a new route in the main.py.
2. Actually this will be a few routes – update, delete, post.
3. Make sure that this route conforms to the password decorator.
4. Create the html page.
5. Add the link to the page in the navigation bar on the main page. 
6. Create the database using SQL
7. Make the database live
8. Make it all work

Base this on my to do list that I’ve already created. 

Just to remember what I’ve got to do

Configuring my environment

1. Set up virtual environment in dropbox/keith/technology/python_projects/elsinore

source elsinore/bin/activate

2. Configure flask:

export FLASK_APP=project

export FLASK_DEBUG=1

3. Run the app

flask run

Setting up the navigation bar

• Inside templates, in the base.html file, I added this. 

  {% if current_user.is_authenticated %}

         <a href=”{{ url_for(‘main.todo’) }}” class=”navbar-item”>

             To do

         </a>

     {% endif %}
