Django+pyecharts realizes movie data analysis visualization

In the previous article, pyecharts realizes the visualization of movie data analysis and has realized the visualization of pyecharts. This article mainly implements Django combined with pyecharts to make a small visual website/system.
I wrote it with Sublime Text on the Centos7 virtual machine, you can do whatever you want.

Create a python virtual environment

I am using Python 3.6.8, as long as you are not Python2 or older, it should work fine.
Go to the directory where you store the python virtual environment, mine is/home/xwk/Desktop/python_vens

[xwk@forpython ~]$ cd Desktop/python_vens/
[xwk@forpython python_vens]$ pwd
/home/xwk/Desktop/python_vens
[xwk@forpython python_vens]$ python3 -V
Python 3.6.8

Create a bookspython virtual environment called

[xwk@forpython python_vens]$ python3 -m venv books

What should I do if I find that I created the wrong name? The movie visualization I made should be created. movies
If you have installed the pip library and don’t want to reinstall it one by one, execute

导出已安装的pip库的名称及版本
pip freeze > requirements.txt

重新创建好虚拟环境后，根据导出的库的名称及版本重新安装
pip install -r requirements.txt

To delete the created wrong environment, just delete the virtual environment directory books, be careful not to delete the wrong one.

[xwk@forpython python_vens]$ rm -rf books/

Recreate moviesthe virtual environment named

[xwk@forpython python_vens]$ python3 -m venv movies

Enter the virtual environment

[xwk@forpython python_vens]$ cd movies/
[xwk@forpython movies]$ source ./bin/activate
(movies) [xwk@forpython movies]$ 

Exit the virtual environment

(movies) [xwk@forpython movies]$ deactivate 
[xwk@forpython movies]$

This is just a demonstration, how to enter and exit the virtual environment, the code needs to enter the virtual environment to run.
Re-enter the virtual environment

[xwk@forpython movies]$ source ./bin/activate
(movies) [xwk@forpython movies]$

Install the required python library

pip install django
pip install pyecharts
pip install pandas
pip install pymysql

pip should automatically install the relevant dependent packages, check the installed packages

(movies) [xwk@forpython movies]$ pip list

Different versions of libraries may have different codes. For example, Django, if you are not the above version, if there is an error in the code, you can search and modify it yourself. This is not difficult, because you are definitely not the only one who has encountered similar problems.

Create a Django project

Go to the directory where you store the python virtual environment, mine is/home/xwk/Desktop/python_projects

(movies) [xwk@forpython movies]$ cd /home/xwk/Desktop/python_projects
(movies) [xwk@forpython python_projects]$

Create a Django project called movies

django-admin startproject movies

(movies) [xwk@forpython python_projects]$ cd movies/
(movies) [xwk@forpython movies]$ ls
manage.py  movies

Configure the mysql database, you can create a named database according to your needs movies. This article mainly uses pandas, and mysql is only needed by django. You can also import csv files into mysql, and use sql statements to query.

mysql> create database movies;
Query OK, 1 row affected (0.00 sec)

(movies) [xwk@forpython movies]$ pwd
/home/xwk/Desktop/python_projects/movies/movies
(movies) [xwk@forpython movies]$ ls
asgi.py  __init__.py  __pycache__  settings.py  urls.py  wsgi.py

Configure the files in this directory settings.pyand change DATABASESthe content to:

DATABASES = {
    
    
    'default': {
    
    
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'movies',
        'USER': 'root',
        'PASSWORD': 'root',
        'HOST': 'localhost',
        'PORT': '3306',
    }
}

__init__.pyAdd to this directory

import pymysql
pymysql.install_as_MySQLdb()

Create a Django application

Create a movies_pyechartsDjango application named
Go to this directory

(movies) [xwk@forpython movies]$ pwd
/home/xwk/Desktop/python_projects/movies
(movies) [xwk@forpython movies]$ ls
manage.py  movies

(movies) [xwk@forpython movies]$ python ./manage.py startapp movies_pyecharts

(movies) [xwk@forpython movies]$ cd movies
(movies) [xwk@forpython movies]$ ls
asgi.py  __init__.py  __pycache__  settings.py  urls.py  wsgi.py

Edit settings.pythe file
to add to INSTALLED_APPS'movies_pyecharts',

(movies) [xwk@forpython movies]$ cd ../movies_pyecharts/
(movies) [xwk@forpython movies_pyecharts]$ ls
admin.py  __init__.py  models.py  tests.py
apps.py   migrations   templates  views.py

Edit (or create new if not) urls.pyfile

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index),
]

(movies) [xwk@forpython movies_pyecharts]$ cd ../movies
(movies) [xwk@forpython movies]$ ls
asgi.py  __init__.py  __pycache__  settings.py  urls.py  wsgi.py

Edit urls.py(note the directory switch)

from django.contrib import admin
from django.urls import path, include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('movies_pyecharts/', include('movies_pyecharts.urls')),
]

movies_pyechartsFirst create a new templatesfolder under the folder
and place the pyecharts template in pyecharts.render.templates for specific location reference ( /home/xwk/Desktop/python_vens/movies/lib/python3.6/site-packages/pyecharts/render/templates)

Copy to the newly created templates folder
and copy the obtained data files to movies_pyechartsthe folder

Open it now http://127.0.0.1:8000/movies_pyecharts/, and you can see the graph!

It's just a page and I try to add pages.

Add more visualization pages

editmovies_pyecharts/urls.py

from django.urls import path
from . import views

urlpatterns = [
    path('', views.index,name='index'),
    path('director/',views.director,name='director'),
]

Add the following code to movies_pyecharts/views.py :

def director(request):
    Director = data['导演'].value_counts()[0:11].reset_index()
    Director.rename(columns={
    
    "index": "导演", "导演": "电影数量"}, inplace=True)
    pie = (
        Pie(init_opts=opts.InitOpts(theme='light'))
        .add(
            series_name='电影类型',
            data_pair=[list(z) for z in zip(
                Director['导演'].to_list(), Director['电影数量'].to_list())],
            radius=["40%", "75%"],
        )
        #     .set_colors(["blue", "green", "yellow", "red", "pink", "orange", "purple"])
        .set_global_opts(
            title_opts=opts.TitleOpts(
                title="导演及电影数量",
                subtitle='TOP10',
                title_textstyle_opts=opts.TextStyleOpts(
                    font_family='Microsoft YaHei',
                    font_weight='bold',
                    font_size=22,
                ),
            ),
            legend_opts=opts.LegendOpts(
                pos_left="left",
                pos_top="center",
                orient='vertical',
                is_show=True
            ),
            toolbox_opts=opts.ToolboxOpts(
                is_show=True,
                pos_left="right",
                pos_top="center",
                feature={
    
    "saveAsImage": {
    
    }}
            )
        )
        .set_series_opts(label_opts=opts.LabelOpts(formatter="{b}: {c}"))
    )
    return HttpResponse(pie.render_embed())

That's it for the Open http://127.0.0.1:8000/movies_pyecharts/director/

Add More Pages method, I won't add any more.

If you want to change the title of the page,
change the code similar to the following

Bar(init_opts=opts.InitOpts(height='700px', theme='light',page_title ='上映年份及电影数量'))

For more configuration, refer to pyecharts official website documentation
. Django is very powerful. The visualization I made is just an introduction.
