使用Django搭建一個基金模擬交易系統(tǒng)教程

更新時間：2019年11月18日 15:09:47 作者：Luzaofa

今天小編就為大家分享一篇使用Django搭建一個基金模擬交易系統(tǒng)教程，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

親手教你如何搭建一個基金模擬系統(tǒng)（基于Django框架）

第一步：創(chuàng)建項目、APP以及靜態(tài)文件存儲文件夾

django-admin startproject Chongyang
django-admin startapp Stock # Chongyang文件夾里面操作

在chongyang項目創(chuàng)建statics和templates兩個文件夾

第二步：配置Setting.py文件

INSTALLED_APPS = [
 'django.contrib.admin',
 'django.contrib.auth',
 'django.contrib.contenttypes',
 'django.contrib.sessions',
 'django.contrib.messages',
 'django.contrib.staticfiles',
 'Stock' # 添加自己的APP名
] 

TEMPLATES = [
 {
 'BACKEND': 'django.template.backends.django.DjangoTemplates',
 'DIRS': [os.path.join(BASE_DIR, 'templates')], # 靜態(tài)文件夾地址（必須配置）
 'APP_DIRS': True,
 'OPTIONS': {
  'context_processors': [
  'django.template.context_processors.debug',
  'django.template.context_processors.request',
  'django.contrib.auth.context_processors.auth',
  'django.contrib.messages.context_processors.messages',
  ],
 },
 },
]

# 數(shù)據(jù)庫配置（使用默認(rèn)sqlite） 
DATABASES = {
 'default': {
 'ENGINE': 'django.db.backends.sqlite3',
 # 'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),
 'NAME': os.path.join(BASE_DIR, 'StockDB.db'),
 }
 }

LANGUAGE_CODE = 'zh-hans' # 漢語
TIME_ZONE = 'Asia/Shanghai' # 時區(qū)

STATIC_URL = '/static/'  # 靜態(tài)文件配置
STATICFILES_DIRS = [
 os.path.join(BASE_DIR, 'statics'), # 具體的路徑
 os.path.join(BASE_DIR, 'templates'),
]

第三步：運行項目

python manage.py runserver 0.0.0.0:8000

到目前為止，你已經(jīng)創(chuàng)建了一個擁有極其龐大功能的web網(wǎng)站，后續(xù)只需激活相應(yīng)的服務(wù)即可

url.py # 路由配置文件
views.py # 功能實現(xiàn)文件
admin.py # 后臺管理文件
model.py # 數(shù)據(jù)庫創(chuàng)建文件

第四步：具體項目配置

在配置好前面設(shè)置后直接在相應(yīng)的文件里復(fù)制如下代碼運行項目即可

1、models.py

from django.db import models
import uuid

# 基金經(jīng)理數(shù)據(jù)表
class Fund_Manger(models.Model):
 name = models.CharField(max_length=20)
 age = models.IntegerField()
 entry_time = models.CharField(max_length=20)
 def __str__(self):
 return self.name

# 股票信息數(shù)據(jù)表
class Stock(models.Model):
 stock_name = models.CharField(max_length=20)
 code = models.CharField(max_length=10)
 def __str__(self):
 return self.code

# 交易系統(tǒng)表
class Trading(models.Model):
 name = models.CharField(max_length=20)
 time = models.DateTimeField()
 code = models.CharField(max_length=10)
 number = models.IntegerField()
 price = models.CharField(max_length=10)
 operate = models.CharField(max_length=10)
 total_price = models.CharField(max_length=20)

# 清算數(shù)據(jù)表
class Fund_pool(models.Model):
 time = models.DateTimeField()
 total_pool = models.CharField(max_length=30)
 oprate_people = models.CharField(max_length=10)
 people_num = models.IntegerField()
 def __str__(self):
 return self.total_pool

2、url.py

from django.contrib import admin
from django.urls import path
from django.conf.urls import url
from Stock import views

urlpatterns = [
 path('admin/', admin.site.urls),
 url(r'^$', views.index),
 url(r'^data_entry/$', views.data_entry, name='data_entry'),
 url(r'^add_fund_manger/$', views.add_fund_manger),
 url(r'^add_stock/$', views.add_stock),
 url(r'^check$', views.check_index, name='check'),
 url(r'^trading/$', views.check),
 url(r'^trading_success/$', views.trading),
 url(r'^fund_pool/$', views.Fund_pool_, name='fund_pool'),
 url(r'^account/$', views.Account)
]

3、views.py

from django.shortcuts import render

# Register your models here.
class Fund_MangerAdmin(admin.ModelAdmin):
 list_display = ('name', 'age', 'entry_time')

class StockAdmin(admin.ModelAdmin):
 list_display = ('stock_name', 'code')

class TradingAdmin(admin.ModelAdmin):
 list_display = ('name', 'time', 'code', 'number', 'price', 'operate', 'total_price')

class Fund_PoolAdmin(admin.ModelAdmin):
 list_display = ('time', 'total_pool', 'oprate_people', 'people_num')

admin.site.register(Fund_Manger, Fund_MangerAdmin)
admin.site.register(Stock, StockAdmin)
admin.site.register(Trading, TradingAdmin)
admin.site.register(Fund_pool, Fund_PoolAdmin)

  </form>
 </div>
</center>
</body>
</html>

第六步：創(chuàng)建表結(jié)構(gòu)，創(chuàng)建超級管理員，運行項目即可

python manage.py makemigrations
python manage.py migrate
python manage.py createsuperuser
python manage.py runserver 0.0.0.0:8000
