自动化监控系统(三) 搭建xadmin做网站后台

Django有个自带的admin后台，不过界面不怎么好看，这里我用xadmin

我的python版本是3.5，可以使用支持py3的xadmin：https://github.com/sshwsfc/xadmin

xadmin部署步骤：

1、把xadmin整个目录拷贝到项目里面

2、需要安装的依赖包：

django~=1.9.0
django-crispy-forms~=1.6.0
django-reversion~=2.0.0
django-formtools==1.0
future==0.15.2
httplib2==0.9.2
six==1.10.0

3、注册xadmin：

把xadmin,crispy_forms,reversion注册到install_apps里面，然后再添加xadmin的url配置就可以了。

import xadmin

urlpatterns = [
    url(r'^xadmin/', xadmin.site.urls),
]

4、使用django的命令行工具生成xadmin数据表，然后创建管理后台的超级用户：

分别执行makemigrations和migrate

 创建管理后台的超级用户

 

接着输入email和passwd就可以登陆了。

英文界面不怎么友好，改成中文（我英语不好）

 在settings里修改配置：

#LANGUAGE_CODE = 'en-us'
LANGUAGE_CODE = 'zh-hans'

# TIME_ZONE = 'UTC'
TIME_ZONE = 'Asia/shanghai'

USE_I18N = True

USE_L10N = True

#这里是指定默认时间，如果为True，则写进数据库的时间是utc时间，需要改成False
USE_TZ = False

 很明显，我在monitor app的model里创建的表在这里没显示，因为xadmin的使用，首先需要对model进行注册，才能在后台管理中进行操作。

1、在app里创建py文件：adminx（必须这个名称）

2、导入xadmin和models里的类，格式如下：

#!/usr/bin/env python
# _*_ coding:utf-8 _*_
__author__ = "BIGNI"
__date__ = "2017/4/9 21:08"

import xadmin

from django import forms

from  monitor import models
# Register your models here.

# from django.contrib.auth.admin import UserAdmin

    """A form for creating new users. Includes all the required
    fields, plus a repeated password."""
    password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
    password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)

    class Meta:
        model = models.UserProfile
        fields = ('email','name')

    def clean_password2(self):
        # Check that the two password entries match
        password1 = self.cleaned_data.get("password1")
        password2 = self.cleaned_data.get("password2")
        if password1 and password2 and password1 != password2:
            raise forms.ValidationError("Passwords don't match")
        return password2

    def save(self, commit=True):
        # Save the provided password in hashed format
        user = super(UserCreationForm, self).save(commit=False)
        user.set_password(self.cleaned_data["password1"])
        if commit:
            user.save()
        return user


class UserChangeForm(forms.ModelForm):
    """A form for updating users. Includes all the fields on
    the user, but replaces the password field with admin's
    password hash display field.

    password = ReadOnlyPasswordHashField(label="Password",
        help_text=("Raw passwords are not stored, so there is no way to see "
                    "this user's password, but you can change the password "
                    "using <a href="password/">this form</a>."))

    class Meta:

    def clean_password(self):
        # Regardless of what the user provides, return the initial value.

        return self.initial["password"]

xadmin.site.register(views.BaseAdminView,BaseSettings)
xadmin.site.register(views.CommAdminView,GlobalSettings)

遇到的问题：

1、

ManyToManyField类型的字段，在xadmin里只显示了一个选项框。解决方法：

在定义的类中，加上这个字段，其中templates对应字段名称，效果如下  style_fields = {'templates': 'm2m_transfer'}
