Django的Admin界面和Flask的后臺管理都是用于管理應用程序數據和用戶的功能。雖然它們有一些相似之處,但它們是基于不同的Python Web框架構建的。在這里,我將向您展示如何優化Django Admin界面以及增強Flask后臺管理。
優化Django Admin界面:
templates/admin
的文件夾,然后將您的自定義模板放入其中。接下來,在您的admin.py
文件中,設置render_template
屬性以使用您的自定義模板。from django.contrib import admin
from django.shortcuts import render
class MyModelAdmin(admin.ModelAdmin):
render_template = 'admin/my_model_change_form.html'
admin.site.register(MyModel, MyModelAdmin)
pip install django-crispy-forms
),然后在您的settings.py
文件中添加crispy_forms
到INSTALLED_APPS
和CRISPY_TEMPLATE_PACK
。最后,在您的admin.py
文件中,使用crispy_forms.admin. crispy_form_for_model
替換form
。from django import forms
from crispy_forms.helper import FormHelper
from crispy_forms.layout import Submit
from django.contrib import admin
from myapp.models import MyModel
class MyModelForm(forms.ModelForm):
class Meta:
model = MyModel
fields = '__all__'
def __init__(self, *args, **kwargs):
super(MyModelForm, self).__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.add_input(Submit('submit', 'Save'))
class MyModelAdmin(admin.ModelAdmin):
form = MyModelForm
admin.site.register(MyModel, MyModelAdmin)
增強Flask后臺管理:
pip install flask-admin
),然后在您的app.py
文件中導入并初始化Flask-Admin。from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_admin import Admin
from myapp.models import MyModel
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///my_database.db'
db = SQLAlchemy(app)
admin = Admin(app, name='My App', template_mode='bootstrap3')
admin.add_view(ModelView(MyModel, db.session))
if __name__ == '__main__':
app.run()
templates/admin
的文件夾,然后將您的自定義模板放入其中。接下來,在您的app.py
文件中,設置template_mode
屬性以使用您的自定義模板。from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_admin import Admin
from flask_admin.contrib.sqla import ModelView
from myapp.models import MyModel
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///my_database.db'
db = SQLAlchemy(app)
admin = Admin(app, name='My App', template_mode='bootstrap3')
admin.add_view(ModelView(MyModel, db.session, template_mode='my_custom_template'))
if __name__ == '__main__':
app.run()
pip install flask-security
),然后在您的app.py
文件中導入并初始化Flask-Security。from flask import Flask
from flask_sqlalchemy import SQLAlchemy
from flask_admin import Admin
from flask_security import Security, SQLAlchemyUserDatastore, UserMixin, RoleMixin, login_required
from myapp.models import MyModel, MyUser, MyRole
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///my_database.db'
app.config['SECRET_KEY'] = 'mysecretkey'
db = SQLAlchemy(app)
roles_users = db.Table('roles_users',
db.Column('user_id', db.Integer(), db.ForeignKey('user.id')),
db.Column('role_id', db.Integer(), db.ForeignKey('role.id')))
class MyUser(db.Model, UserMixin):
id = db.Column(db.Integer, primary_key=True)
email = db.Column(db.String(255), unique=True)
password = db.Column(db.String(255), nullable=False)
active = db.Column(db.Boolean())
confirmed_at = db.Column(db.DateTime())
roles = db.relationship('MyRole', secondary=roles_users, backref=db.backref('users', lazy='dynamic'))
class MyRole(db.Model, RoleMixin):
id = db.Column(db.Integer, primary_key=True)
name = db.Column(db.String(80), unique=True)
description = db.Column(db.String(255))
user_datastore = SQLAlchemyUserDatastore(db, MyUser, MyRole)
security = Security(app, user_datastore)
admin = Admin(app, name='My App', template_mode='bootstrap3')
admin.add_view(ModelView(MyModel, db.session))
if __name__ == '__main__':
app.run()
通過這些方法,您可以優化Django Admin界面并增強Flask后臺管理。
