如何以django格式将上下文数据作为dict/list/any格式传递给另一个文件？

Question

在我的项目中，我试图对用户选择的汽车进行评论。在django应用程序中，我希望将上下文字典中的数据传递给另一个scrape.py文件。代码：

models.py

class SelectCar(models.Model):
    BRANDS = (
        ('BMW','BMW'),
        ('MR','Mercedes')
    )
    brand = models.CharField(max_length=30,
                  choices=BRANDS,
                  default="BMW")
    CAR_MODELS = (
        ('X1','X1'),
        ('X2','X2'),
        ('X3','X3')

    )

    car_model = models.CharField(max_length=30,
                  choices=CAR_MODELS,
                  default="X1")

forms.py

from .models import SelectCar

class SelectCarForm(forms.ModelForm):
  
    class Meta:
        model = SelectCar
        fields = '__all__'

scrape.py，在这里，我希望导入上下文数据，并在if- chain链中为特定的car选择url。例如，如果选择的汽车是本田惊奇，上下文应该导入到scrape.py，以便我能够选择url。

import requests
from bs4 import BeautifulSoup
"""import context here in some way"""

def happyScrape():

    """here, import the context and choose url based on chosen car
    if car is Honda amaze, choose url for honda amaze and so on.
    example- if brand is honda and model is amaze, 
    """
    url = 'https://www.carwale.com/honda-cars/amaze/user-reviews/'\
   


    headers = {'User-Agent': 'Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/47.0.2526.106 Safari/537.36'}
    cw_result = requests.get(url, headers=headers)

    cw_soup = BeautifulSoup(cw_result.text, 'html5lib')



    scrapeList  =[] 

    #scrape code here, stored in scrapeListHTML

    for data in scrapeListHtml:
        scrapeList.append(data.text)


    with open(r'./scrape/scrapeListFile.txt', 'w') as f:
        for item in scrapeList:
            # write each item on a new line
            f.write("%s\n" % item)

views.py

from .forms import SelectCarForm
def ScrapeView(request):

    
    context = {}
    context['SelectCarForm'] = SelectCarForm()
    
    if request.method == 'POST' and 'run_script' in request.POST:
        from .scrape import happyScrape

        happyScrape()       
        
    return render(request, "scrape.html", context)

编辑通过将数据以品牌的形式传递给happyScrape()本身，car_model解决了这个问题。

在context函数中传递来自happyScrape()的特定数据。

在scrape.py中

def happyScrape(data):

   # use this data here
   ...

在views.py中

def ScrapeView(request):

   ...
   
   happyScrape(<data_from_context>)
   
   ...
