Django导入类来自models.py [英] Django Import Class From models.py
本文介绍了Django导入类来自models.py的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
使用这样的文件夹结构:
library /
-django.wsgi
-manage .py
-static /
- 我的静态文件
-library /
--__init__.py
--models.py
- settings.py
--urls.py
--views.py
--wsgi.py
--templates /
---我打算存储的地方我所有的模板
如何在我的views.py中导入一个在models.py中定义的类?
我尝试过:
import models.class
from models import class
from projectname.models import class
from projectname import models.class
从项目导入类
但是对于所有这些我得到无效的语法错误
views.py
from django.core.context_processors import csrf
from django导入重定向,从django.contrib.auth导入验证
,从django.contrib.auth.decorators导入login_required
从django.contrib.auth.models导入用户
from django.http import HttpResponse
from django.contrib import message
from django.template import RequestContext,loader
from django.contrib.auth import logout
从library.models import 7DTagmap
models.py
$ _ code从__future__导入unicode_literals
从django.db导入模型
class 7DTagmap(mo dels.Model):
id = models.IntegerField(primary_key = True)
tag_id = models.CharField(max_length = 50L)
st_tag_id = models.IntegerField()
class Meta :
db_table ='7d_tagmap'
错误:
无效语法(views.py,第11行)
异常类型:SyntaxError
异常值:无效语法(views.py,第11行)
解决方案
使用:
from library.models import MyClass
你应该很好:)
(基本结构是< app> .models import< ModelName> $中的 c $ c>)
更新:
问题是(几乎! )肯定你的模型以'7'开头 - 把它改成一个字母,一切都会很好,我(几乎!)肯定:)
Using a folder structure like this:
library/
-django.wsgi
-manage.py
-static/
--all my static files
-library/
--__init__.py
--models.py
--settings.py
--urls.py
--views.py
--wsgi.py
--templates/
---where i plan to store all my templates
How can i import a class in my views.py that is defined in models.py?
I've tried:
from . import models.class
from models import class
from projectname.models import class
from projectname import models.class
from project import class
But for all those i get invalid syntax errors
views.py
from django.core.context_processors import csrf
from django.shortcuts import redirect, render
from django.contrib.auth import authenticate, login
from django.contrib.auth.decorators import login_required
from django.contrib.auth.models import User
from django.http import HttpResponse
from django.contrib import messages
from django.template import RequestContext, loader
from django.contrib.auth import logout
from library.models import 7DTagmap
models.py
from __future__ import unicode_literals
from django.db import models
class 7DTagmap(models.Model):
id = models.IntegerField(primary_key=True)
tag_id = models.CharField(max_length=50L)
st_tag_id = models.IntegerField()
class Meta:
db_table = '7d_tagmap'
error:
invalid syntax (views.py, line 11)
Exception Type: SyntaxError
Exception Value: invalid syntax (views.py, line 11)
解决方案
use:
from library.models import MyClass
and you should be good to go :)
(the basic structure is from <app>.models import <ModelName>
)
update:
the problem is (almost!) certainly that your model begins with '7' -- change it to a letter character, and all will be well, I'm (almost!) sure :)
