django安装xadmin及问题解决
作者:angfulin
环境:
- Windows 10 专业版
- pycharm pro 2020.3
- django 3.2.1
- xadmin 选django2的版本
一,安装
这里我选择从 GitHub 安装:
pip install git+https://github.com/sshwsfc/xadmin.git
结果如下:
Successfully installed
defusedxml-0.7.1
diff-match-patch-20200713
django-crispy-forms-1.11.2
django-formtools-2.3
django-import-export-2.5.0
django-reversion-3.0.9
et-xmlfile-1.1.0 future-0.18.2
httplib2-0.9.2
markuppy-1.14
odfpy-1.4.1
openpyxl-3.0.7
pyyaml-5.4.1
six-1.16.0
tablib-3.0.0
xadmin-0.6.1 xlrd-2.0.1
xlwt-1.3.0
二,注册 xadmin:
'xadmin',
'crispy_forms',
'reversion',
crispy_forms与reversion是xadmin的依赖包,使用上面的命令会自动安装。
三,配置 URL:
其余代码
from xadmin.plugins import xversion import xadmin xversion.register_models() xadmin.autodiscover() urlpatterns = [ 其余代码 path('xadmin/', xadmin.site.urls), ]
四,数据迁移并创建超级用户
五,收集media
python manage.py collectstatic
六,运行项目,解决错误
运行项目,出现下面的报错:
1,ImportError: cannot import name ‘six’ from ‘django.utils’
在 site-packages 目录中找到 six.py 文件,将它复制到 django/utils 目录下。
运行项目,出现下面的报错。
2,No module named ‘django.core.urlresolvers’
有博客说是:
因为Django 3.x 已经把django.core.urlresolvers模块的内容迁移至django.urls中
将:
from django.core.urlresolvers import reverse 改为: from django.urls import reverse
这个错误多次出现,直接按上面的方法处理。
运行项目,出现下面的报错。
3,ImportError: cannot import name ‘python_2_unicode_compatible’ from ‘django.utils.encoding’
将: from django.utils.encoding import python_2_unicode_compatible, smart_text 改为: from django.utils.encoding import smart_text from six import python_2_unicode_compatible
运行项目,出现下面的报错。
4,ImportError: cannot import name ‘pretty_name’ from ‘django.forms.forms’
将: from django.forms.forms import pretty_name 改为: from django.utils import formats, six
运行项目,出现下面的报错。
5,ModuleNotFoundError: No module named ‘django.contrib.staticfiles.templatetags’
将: from django.contrib.staticfiles.templatetags.staticfiles import static 改为: from django.templatetags.static import static
运行项目,出现下面的报错。
6,TypeError: init() missing 1 required positional argument: ‘on_delete’
这个错误多次出现,直接在字段中添加:
on_delete=models.CASCADE
运行项目,出现下面的报错。
7,TypeError: init() takes 1 positional argument but 6 were given
将: forms.Field.__init__(self, required, widget, label, initial, help_text, *args, **kwargs) 改为: forms.Field.__init__(self)
运行项目,出现下面的报错。
8,ImportError: cannot import name ‘login’ from ‘django.contrib.auth.views’
将: from django.contrib.auth.views import login 改为: from django.contrib.auth.views import LoginView as login 将: from django.contrib.auth.views import logout 改为: from django.contrib.auth.views import LogoutView as logout
随之而来的同文件下的改动:
注释掉 class LoginView(BaseAdminView) 与 class LogoutView(BaseAdminView) 的 get 方法中 defaults 字典的 'current_app': self.admin_site.name, 修改 class LoginView(BaseAdminView) 与 class LogoutView(BaseAdminView) 的 get 方法中 return 为 return login.as_view(**defaults)(request) 与 return logout.as_view(**defaults)(request)
运行项目,出现下面的报错。
9,ImportError: cannot import name ‘FieldDoesNotExist’ from ‘django.db.models.fields’
先安装 django-advanced-filters,
再:
将: from django.db.models.fields import FieldDoesNotExist 改为: from django.core.exceptions import FieldDoesNotExist
运行项目,出现下面的报错。
10,ImportError: cannot import name ‘QUERY_TERMS’ from ‘django.db.models.sql.query’
将: from django.db.models.sql.query import LOOKUP_SEP, QUERY_TERMS 改为: from django.db.models.sql.query import LOOKUP_SEP, Query
同文件下,将:
if len(parts) > 1 and parts[-1] in QUERY_TERMS: 改为: if len(parts) > 1 and parts[-1] in Query:
运行项目,出现下面的报错。
11,ModuleNotFoundError: No module named ‘requests’
安装requests
运行项目,出现下面的报错。
12,ImportError: cannot import name ‘FieldDoesNotExist’ from ‘django.db.models’
将: from django.db.models import FieldDoesNotExist, Avg, Max, Min, Count, Sum 改为: from django.core.exceptions import FieldDoesNotExist from django.db.models import Avg, Max, Min, Count, Sum
运行项目,出现下面的报错。
13,ImportError: cannot import name ‘password_reset_confirm’ from ‘django.contrib.auth.views’
将: from django.contrib.auth.views import password_reset_confirm 改为: from django.contrib.auth.views import PasswordResetConfirmView
运行项目,出现下面的报错。
14,AttributeError: ‘Settings’ object has no attribute ‘MIDDLEWARE_CLASSES’
在 language.py 中修改:
将: if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE_CLASSES: 改为: if settings.LANGUAGES and 'django.middleware.locale.LocaleMiddleware' in settings.MIDDLEWARE:
运行项目,出现下面的报错。
15,ImportError: cannot import name ‘SKIP_ADMIN_LOG’ from ‘import_export.admin’
将: from import_export.admin import DEFAULT_FORMATS, SKIP_ADMIN_LOG, TMP_STORAGE_CLASS 改为: from import_export.admin import DEFAULT_FORMATS,ImportMixin,ImportExportMixinBase
七,访问xadmin
创建超级用户后,运行项目,访问http://127.0.0.1:8000/xadmin/,
16,AttributeError: ‘Media’ object has no attribute ‘add_css’
将: def vendor(*tags): 改为: def vendor(*tags): media = Media() css = {'screen':[]} js = [] for tag in tags: file_type = tag.split('.')[-1] files = xstatic(tag) if file_type == 'js': # media.add_js(files) js.extend(files) elif file_type == 'css': # media.add_css({'screen': files}) css['screen'] += files # return media return Media(css=css, js=js)
运行项目,出现下面的报错。
17,ImportError: cannot import name ‘javascript_catalog’ from ‘django.views.i18n’
将: def i18n_javascript(self, request): if settings.USE_I18N: from django.views.i18n import javascript_catalog else: from django.views.i18n import null_javascript_catalog as javascript_catalog return javascript_catalog(request, packages=['django.conf', 'xadmin']) 改为: def i18n_javascript(self, request): # if settings.USE_I18N: # from django.views.i18n import javascript_catalog # else: # from django.views.i18n import null_javascript_catalog as javascript_catalog from django.views.i18n import JavaScriptCatalog # return javascript_catalog(request, packages=['django.conf', 'xadmin']) return JavaScriptCatalog.as_view(packages=['django.conf', 'xadmin'])(request)
访问http://127.0.0.1:8000/xadmin/。
点击左侧 Revisions 出现下面的报错。
18,AttributeError: ‘DateTimeField’ object has no attribute ‘rel’
将: if isinstance(field.rel, models.ManyToOneRel): 改为: if isinstance(field.remote_field, models.ManyToOneRel):
这个错误会在第一次点击左边的所有导航内容时出现,只需将 rel 改为 remote_field 就行。
点击主页的“添加小组件”按钮时,出现下面报错。
19,TypeError: render() got an unexpected keyword argument ‘renderer’
将 xadmin\views\dashboard.py WidgetTypeSelect类中: def render(self, name, value, attrs=None): 改为: def render(self, name, value, attrs=None, renderer=None):
或者
将/lib/site-packages/django/forms/boundfield.py中as_widget的return的最后一个参数注释掉。
OK! 暂时到这里吧,后面遇到问题再在下面补充。
之所以在 django3.2.1 中使用 xadmin 会出现这么多报错,是因为 xadmin 针对 django 进行开发的版本最多到 djang 2,后面 xadmin 成为一个完全的前端框架,对 django 的专门支持不如以前了。
八,问题补充
20,‘ManyToOneRel’ object has no attribute ‘to’
将: self.add_url, (_('Create New %s') % self.rel.to._meta.verbose_name), name, 改为: self.add_url, (_('Create New %s') % self.rel), name,
21,‘Media’ object has no attribute ‘add_js’
将xadmin/util.py的: def vendor(*tags): media = Media() for tag in tags: file_type = tag.split('.')[-1] files = xstatic(tag) if file_type == 'js': media.add_js(files) elif file_type == 'css': media.add_css({'screen': files}) return media 改为: def vendor(*tags): css = {'screen': []} js = [] for tag in tags: file_type = tag.split('.')[-1] files = xstatic(tag) if file_type == 'js': js.extend(files) elif file_type == 'css': css['screen'] += files return Media(css=css, js=js)
22,AttributeError: module ‘django.db.models’ has no attribute ‘FieldDoesNotExist’
报错文件:venv/lib/python3.8/site-packages/xadmin/views/list.py:
我暂时无法解决!!
23,AttributeError: ‘ForeignKey’ object has no attribute ‘rel’
参考问题 18。
24,AttributeError: ‘CharField’ object has no attribute ‘rel’
参考问题 18。
25,AttributeError: ‘ManyToManyField’ object has no attribute ‘rel’
参考问题 18。
26,Exception: Relate Lookup field must a related field
将 xadmin\util.py的:
return (hasattr(field, 'rel') and field.rel != None) or is_related_field(field) 修改为: return (hasattr(field, 'remote_field') and field.remote_field != None) or is_related_field(field)
27,AttributeError: ‘set’ object has no attribute ‘get_field_names’
28,TypeError: get_deleted_objects() takes 3 positional arguments but 5 were given
将: deletable_objects, model_count, perms_needed, protected = get_deleted_objects( queryset, self.opts, self.user, self.admin_site, using) 改成: deletable_objects, model_count, perms_needed, protected = get_deleted_objects( queryset, self.user, self.admin_site)
29,AttributeError at /xadmin/xadmin/userwidget/4/delete/ type object ‘xadminuserwidgetAdmin’ has no attribute ‘has_delete_permission’
这个问题在我删除已存在的”用户小组件“时出现。
直接注释掉报错处:
# if not admin_site._registry[model].has_delete_permission(request, obj):
# perms_needed.add(opts.verbose_name)
30,IndexError: list index out of range
将: input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).replace('/><input', '/>\n<input').split('\n') if ht != ''] 改为: input_html = [ht for ht in super(AdminSplitDateTime, self).render(name, value, attrs).split('/><') if ht != ''] input_html[0] = input_html[0] + "/>" input_html[1] = "<" + input_html[1]

建议还是别用django-xadmin了,Simple UI、grappelli 它们不更香吗?
