迁移Django遇到的问题记录

经验部分

兼容性测试

python -Wd manage.py runserver
python -Wa manage.py runserver

一共有四类：

第一类：RemovedInDjango20Warning: on_delete will be a required arg for ForeignKey in Django 2.0

第二类：RemovedInDjango20Warning: Old-style middleware using settings.MIDDLEWARE_CLASSES is deprecated. Update your middleware and use settings.MIDDLEWARE instead.

第三类：RemovedInDjango20Warning: assignment_tag() is deprecated. Use simple_tag() instead

第四类： ImportWarning: Not importing directory

这些警告主要是升级到2.0要修复的问题，暂不处理

框架部分

The problem is that one of your applications (foo.app.scripts) imports 
models in its top-level __init__.py. This is not supported; for an 
explanation, you can read

解决方案：

修改apps.py文件

# 移动到函数内部
# from role.models import RoleType, UserRole

def app_ready_handler(sender, **kwargs):
    print 'init builtin roles and user roles data'
    from role.models import RoleType, UserRole
    try:
        RoleType.init_builtin_roles()
        UserRole.init_builtin_user_roles()
    except Exception as e:
        print 'init builtin roles and user roles data exception: %s' % e

django-smart-autoregister 不兼容1.11

Compatibility

Tested with Django 1.4, 1.5, 1.6, 1.7, 1.8

Tested with Python 2.7, 3.3, 3.4 and PyPy

# models中没有get_app方法

models.get_app

# https://github.com/bmihelac/django-cruds/issues/3
# Latest supported Django is 1.11

解决方案：

TODO：

fork django-smart-autoregister，并修改兼容1.11（干脆先注释了吧，不影响主功能）

Use of patterns is deprecated since django 1.8. See docs. You can use plain lists now.

https://docs.djangoproject.com/en/1.10/releases/1.10/#features-removed-in-1-10

Support for calling a SQLCompiler directly as an alias for calling its quote_name_unless_alias method is removed.
The cycle and firstof template tags are removed from the future template tag library.
django.conf.urls.patterns() is removed.
Support for the prefix argument to django.conf.urls.i18n.i18n_patterns() is removed.

解决方案：

修改用到patterns的urls.py

# 修改前
from django.conf.urls import patterns, url

urlpatterns = patterns(
    'misc.views',
    url(?developer/article/1421534/r&),
    url(?developer/article/1421534/r&),

    url(?developer/article/1421534/r&),
    url(?developer/article/1421534/r&),
)

# 修改后

from django.conf.urls import url

from misc import views

urlpatterns = [
    url(r'^upload_file/$', views.upload),
    url(?developer/article/1421534/r&),
    url(?developer/article/1421534/r&),

Django 1.10 no longer allows you to specify views as a string (e.g. 'myapp.views.home') in your URL patterns.

The solution is to update your urls.py to include the view callable. This means that you have to import the view in your urls.py. If your URL patterns don't have names, then now is a good time to add one, because reversing with the dotted python path no longer works.

解决方案：

# 全局生效：不推荐生产环境使用
urlpatterns += [
    # wiki上传图片404也可以这样简单解决：路由层面不复用MEDIA_URL，后者只用来生成url，比如可以自定义prefix为SITE_URL
    url(r'^media/(?P<path>.*)$',
        'django.views.static.serve', {'document_root': settings.MEDIA_ROOT}),
]

修改为

from django.views import static

# 全局生效：不推荐生产环境使用
urlpatterns += [
    # wiki上传图片404也可以这样简单解决：路由层面不复用MEDIA_URL，后者只用来生成url，比如可以自定义prefix为SITE_URL
    url(r'^media/(?P<path>.*)$',
        static.serve, {'document_root': settings.MEDIA_ROOT}),
]
