Question

我想从django视图调用带有参数的python脚本。 python脚本存储在子文件夹中（参见附图）。

基本上我有一个输入表单，想要使用该表单中的输入数据调用crawl.py。表格数据应存储在变量＆＃34; production_number＆＃34;在crawl.py。

view.py

from .forms import CustomerForm, LoginForm
from .models import Orders

from .ERPProgramm.crawl import crawlmain

def newOrders(request):

if request.method == 'POST':
    form = CustomerForm(request.POST)
    if form.is_valid():
        formdata = form.cleaned_data['product_ID']

        # call crawl.py with paramter formdata 

        return HttpResponseRedirect('/customer/newOrders')

crawl.py

import db
import sys
import requests
import json
from datetime import datetime

def query(resource):
    r = requests.get('http://11.111.11.11:8080/webapp/api/v1/' + resource,
        headers={'AuthenticationToken': '11111-11111-1111-1111-11111'}
    )
    return r


costumer_id = 1
production_number = formdata

d = query('productionOrder/?productionOrderNumber-eq={}'.format(production_number)).json()

session = db.Session()

costumer = session.query(db.Costumer).get(costumer_id)

if 'result' in d and len(d['result']) > 0:
    r = d['result'][0]
    order = db.Order()
    try:
        order.article_id = r['articleId']
        order.amount = r['targetQuantity']
        order.create_date = datetime.fromtimestamp(r['createdDate'] / 1000)
        order.start_date = datetime.fromtimestamp(r['targetStartDate'] / 1000)
        order.end_date = datetime.fromtimestamp(r['targetEndDate'] / 1000)
    except NameError as e:
        sys.exit('Error {}'.format(e.what()))

    article_number = r['articleNumber']
    d = query('article/?articleNumber-eq={}'.format(article_number)).json()

    if 'result' in d and len(d['result']) > 0:
        r = d['result'][0]
        article_image_id = r['articleImages'][0]['id']
        order.price_offer = r['articlePrices'][0]['price']

        r = query('article/id/{}/downloadArticleImage?articleImageId={}'.format(order.article_id, article_image_id))

        order.article_image = r.content
    else:
        print('No result for article with number', article_number)

    costumer.orders.append(order)

    session.add(costumer)
    session.commit()
else:
    print('No result for production order with article number', article_number)

如何从django视图调用crawl.py？

Answer 1

你可以check this 在您的情况下，您需要找到准确的文件路径来执行此操作，您需要在settings.py中找到基础目录中的路径，将其导入view.py。

settings.py

# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
FILE_DIR = os.path.abspath(os.path.join(BASE_DIR,'/Customer/ERPProgram')

views.py

import sys
sys.path.insert(0, os.path.join(settings.FILE_DIR))
import crawl
