import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'first_project.settings')

import django
django.setup()

#FAKE POP SCRIPT
import random
from first_app.models import Topic, AccessRecord, Webpage
from faker import Faker

fakegen = Faker()
topics = ['Search', 'Social', 'Market', 'News', 'Games']

def add_topic():
    t = Topic.objects.get_or_create(top_name = random.choice(topics))[0]
    t.save()
    return t
def populate(N=5):

    for entry in range(N):
        #Get the topic for the entry
        top = add_topic()
    
        #Create the fake data for that entry
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()
    
        #Create the new webpage entry
        webpg = Webpage.objects.get_or_create(topic = top,url = fake_url, name = fake_name)[0]
    
        #Create a fake access record for that webpage
        acc_rec = AccessRecord.objects.get_or_create(name = webpg, date = fake_date)[0]
    
        if __name__ == '__main__':
            print("populating script!")
            populate(20)
            print("populating complete!")

代码执行但不执行任何操作。我已经尝试卸载faker并再次安装,安装旧版本,我也尝试使用pip和anaconda安装,但这些都不起作用。我会感激任何帮助。

的缩进 if __name__ == '__main__': 是错误的。正确的方法是在 populate 功能如下:

import os
os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'first_project.settings')

import django
django.setup()

#FAKE POP SCRIPT
import random
from first_app.models import Topic, AccessRecord, Webpage
from faker import Faker

fakegen = Faker()
topics = ['Search', 'Social', 'Market', 'News', 'Games']

def add_topic():
    t = Topic.objects.get_or_create(top_name = random.choice(topics))[0]
    t.save()
    return t
def populate(N=5):

    for entry in range(N):
        #Get the topic for the entry
        top = add_topic()
    
        #Create the fake data for that entry
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()
    
        #Create the new webpage entry
        webpg = Webpage.objects.get_or_create(topic = top,url = fake_url, name = fake_name)[0]
    
        #Create a fake access record for that webpage
        acc_rec = AccessRecord.objects.get_or_create(name = webpg, date = fake_date)[0]
    
if __name__ == '__main__':
    print("populating script!")
    populate(20)
    print("populating complete!")

使用进行测试 minimal-reproducible-example 它的工作原理是:

from faker import Faker

fakegen = Faker()

def populate(N=5):
    for _ in range(N):
        #Create the fake data for that entry
        fake_url = fakegen.url()
        fake_date = fakegen.date()
        fake_name = fakegen.company()
        print(fake_url, fake_date, fake_name)

if __name__ == '__main__':
    print("populating script!")
    populate(20)
    print("populating complete!")

输出

populating script!
