Script creates a project with the MVC pattern
=============================================
.. versionadded:: 1.0.0
.. seealso::
`MVC pattern <https://en.wikipedia.org/wiki/Model–view–controller>`_
.. rubric:: Use a clean architecture for your applications.
.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/preview-mvc.png
:align: center
Use a clean architecture for your applications. KivyMD allows you to quickly
create a project template with the MVC pattern. So far, this is the only
pattern that this utility offers. You can also include database support in
your project. At the moment, support for the Firebase database
(the basic implementation of the real time database) and RestDB
(the full implementation) is available.
Project creation
----------------
Template command::
kivymd.create_project \\
name_pattern \\
path_to_project \\
name_project \\
python_version \\
kivy_version
Example command::
kivymd.create_project \\
MVC \\
/Users/macbookair/Projects \\
MyMVCProject \\
python3.10 \\
2.1.0
This command will by default create a project with an MVC pattern.
Also, the project will create a virtual environment with Python 3.10,
Kivy version 2.1.0 and KivyMD master version.
.. note::
Please note that the Python version you specified must be installed on your
computer.
.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/mvc-base.png
:align: center
Creating a project using a database
-----------------------------------
.. note::
Note that in the following command, you can use one of two database names:
'firebase' or 'restdb'.
Template command::
kivymd.create_project \\
name_pattern \\
path_to_project \\
name_project \\
python_version \\
kivy_version \\
--name_database
Example command::
kivymd.create_project \\
MVC \\
/Users/macbookair/Projects \\
MyMVCProject \\
python3.10 \\
2.1.0 \\
--name_database restdb
This command will create a project with an MVC template by default.
The project will also create a virtual environment with Python 3.10,
Kivy version 2.1.0, KivyMD master version and a wrapper for working with
the database restdb.io.
.. image:: https://github.com/HeaTTheatR/KivyMD-data/raw/master/gallery/kivymddoc/mvc-database.png
:align: center
.. code-block:: python
class DataBase:
def __init__(self):
database_url = "https://restdbio-5498.restdb.io"
api_key = "7ce258d66f919d3a891d1166558765f0b4dbd"
.. note::
Please note that `database.py` the shell in the `DataBase` class uses the
`database_url` and `api_key` parameters on the test database (works only in read mode),
so you should use your data for the database.
Create project with hot reload
------------------------------
Template command::
kivymd.create_project \\
name_pattern \\
path_to_project \\
name_project \\
python_version \\
kivy_version \\
--use_hotreload
Example command::
kivymd.create_project \\
MVC \\
/Users/macbookair/Projects \\
MyMVCProject \\
python3.10 \\
2.1.0 \\
--use_hotreload yes
After creating the project, open the file `main.py`, there is a lot of useful
information. Also, the necessary information is in other modules of the project
in the form of comments. So do not forget to look at the source files of the
created project.
Create project with responsive view
-----------------------------------
When creating a project, you can specify which views should use responsive
behavior. To do this, specify the name of the view/views in the
`--use_responsive` argument:
Template command::
kivymd.create_project \\
name_pattern \\
path_to_project \\
name_project \\
python_version \\
kivy_version \\
--name_screen FirstScreen SecondScreen ThirdScreen \\
--use_responsive FirstScreen SecondScreen
The `FirstScreen` and `SecondScreen` views will be created with an responsive
architecture. For more detailed information about using the adaptive view, see
the `MDResponsiveLayout <https://kivymd.readthedocs.io/en/latest/components/responsivelayout/>`_
widget.
Others command line arguments
=============================
Required Arguments
------------------
- pattern
- the name of the pattern with which the project will be created
- directory
- directory in which the project will be created
- name
- project name
- python_version
- the version of Python (specify as `python3.9` or `python3.8`) with
- which the virtual environment will be created
- kivy_version
- version of Kivy (specify as `2.1.0` or `master`) that will be used in the project
Optional arguments
------------------
- name_screen
- the name of the class which be used when creating the project pattern
When you need to create an application template with multiple screens,
use multiple values separated by a space for the `name_screen` parameter,
for example, as shown below:
Template command::
kivymd.create_project \\
name_pattern \\
path_to_project \\
name_project \\
python_version \\
kivy_version \\
--name_screen FirstScreen SecondScreen ThirdScreen
- name_database
- provides a basic template for working with the 'firebase' library
- or a complete implementation for working with a database 'restdb.io'
- use_hotreload
- creates a hot reload entry point to the application
- use_localization
- creates application localization files
- use_responsive
- the name/names of the views to be used by the responsive UI
.. warning:: On Windows, hot reloading of Python files may not work.
But, for example, there is no such problem in macOS. If you fix this,
please report it to the KivyMD community.
