Mastering Flask

Connecting to and querying databases can be verbose 

We have a universal connection. But now we need to create an API to make the queries. 

We have a universal connection and have set up a universal query interface. Let's start reading data. 

Data is rarely isolated. We need a way to match the records of relationship A to the records of relationship B in such a way that a record in relationship A can link to multiple records in relationship B, but a record in B is linked to only one record in A. 

We need a way to match relationship A and relationship B in such a way that a record in relationship A can link to multiple records in relationship B and vice versa. 

How can SQLAlchemy represent the more complex queries that can be created in SQL?

Jinja provides an easy way to replace values in an HTML document, but to structure dynamic pages, our Jinja templates need control logic. 

Creating secure forms that cover all of the validation issues in web forms involves a lot of boilerplate code. 

Many of our routes contain common attributes. We need an easy way to share this attributes between them. 

Our app is getting larger. We need a way to split our app.py file into multiple files. 

Our site is fully functional, but we can't have any user-added content, such as comments, without a user system. 

In this video, we're going to cover how to handle encrypted passwords. 

In this video, we're going to make our new login system accessible to users from the frontend. 

In this video, we are going to add functionality to our app that allows us define where each user can and cannot go. 

The aim of this video is to cover a basic overview of RESTful APIs. 

In this video we're going to create REST API using Flask-RESTful. 

Our app needs a way for maintainers of the site to edit and administer the site from the Web. We will provide this functionality with Flask Admin. 

The only way to create new data in the database currently is to use the shell interface. We need an administrator interface to add data from the Web. 

Currently, in all the places where movie posters or actor pictures should be, there are placeholder images. Let's fix that with Flask Admin. 

When developing the app, we don't have a way of viewing the internals of Flask without a lot of print statements. 

Currently, our app renders a template every time a page is loaded, even though the data on the page doesn't change that often. 

One easy way to speed up page load times is to concatenate our CSS and JS files in one file each. But this process can be tedious to do manually. 

Some functions or features in our application are too slow to run in the same process as our Flask server. 

Now that Celery is set up, we need to understand how to send it commands. 

Now that we understand how Celery works and how to give it a task, we will apply this knowledge for something practical. 

Our application has a lot of code in it now; we need to make sure that our code isn't buggy without manually testing every change. 

Now that we understand how unit tests work, let's build some tests for our SQLAlchemy models. 

We now understand how to use the unittest library; next, we need to understand Python's test client. 

Now that we are testing a lot of our application, we need a way to easily know what parts of our application are not being tested.
