![]() ![]() In fact, SQLite is perfectly capable of handling quite big applications. And it doesn't need an External Database Server, so it will be perfect for learning. Python has integrated support for SQLite, it is a single file read and processed from Python. Remember that SQLite is a simple database in a single file?įor most of the tutorial I'll use SQLite for the examples. > 100% Successfully installed sqlmodel pydantic sqlalchemyĪs SQLModel is built on top of SQLAlchemy and Pydantic, when you install sqlmodel they will also be automatically installed. # (env ) $$ python -m pip install sqlmodel ![]() In very short, a virtual environment is a small directory that contains a copy of Python and all the libraries you need to run your code.Īnd when you "activate" it, any package that you install, for example with pip, will be installed in that virtual environment. If you don't know what that is, you can read the official tutorial for virtual environments, it's quite simple. When writing Python code, you should always use virtual environments in one way or another. If you don't have a valid Python version installed, go and install that first. If you have different versions and python3 is not the latest, make sure you use the latest version you have available. ![]() Nice! This works □ Python 3.9.0 // In this case, we would continue using python3.9 instead of python3 Oh, no, this one is not available □ command not found: python3.10 $ python3.9 -version This is too old! □ Python 3.5.6 // Let's see if python3.10 is available $ python3.10 -version Let's check with just python3 $ python3 -version What I normally do is that I create a directory named code inside my home/user directory.Īnd inside of that I create one directory per project. Please go ahead and create a directory for the project we will work on on this tutorial. You can learn a lot more by running some examples and playing around with them than by reading all the docs here. Running the examples is what will really help you understand what is going on. Using it in your editor is what really shows you the benefits of SQLModel, seeing how much code it saves you, and all the editor support you get, with autocompletion and in-editor error checks, preventing lots of bugs. It is HIGHLY encouraged that you write or copy the code, edit it, and run it locally. Run the code ¶Īll the code blocks can be copied and used directly (they are tested Python files). So you can come back and see exactly what you need. It is also built to work as a future reference. This tutorial shows you how to use SQLModel with all its features, step by step.Įach section gradually builds on the previous ones, but it's structured to separate topics, so that you can go directly to any specific one to solve your specific needs. SQLModel uses type annotations for everything, this way you can use a familiar Python syntax and get all the editor support possible, with autocompletion and in-editor error checking. If you need a refresher about how to use Python type hints (type annotations), check FastAPI's Python types intro.
