BaseView
所有的view都必须继承自BaseView：
复制代码 代码如下:
class BaseView(name=None, category=None, endpoint=None, url=None, static_folder=None, static_url_path=None)
name: view在页面上表现为一个menu（超链接），menu name == 'name'，缺省就用小写的class name
category: 如果多个view有相同的category就全部放到一个dropdown里面（dropdown name=='category'）
endpoint: 假设endpoint='xxx'，则可以用url_for(xxx.index)，也能改变页面URL（/admin/xxx）
url: 页面URL，优先级url > endpoint > class name
static_folder: static目录的路径
static_url_path: static目录的URL
anotheradmin.html:
{% extends 'admin/master.html' %}
{% block body %}
Hello World from AnotherMyAdmin!<br/>
<a href="{{ url_for('.test') }}">Click me to go to test view</a>
{% endblock %}
import os
import os.path as op
from flask import Flask
from flask.ext import admin
from flask.ext.admin.contrib import fileadmin
# Create flask app
app = Flask(__name__, template_folder='templates', static_folder='files')
# Create dummy secrey key so we can use flash
app.config['SECRET_KEY'] = '123456790'
# Flask views
@app.route('/')
def index():
return '<a href="/admin/">Click me to get to Admin!</a>'
if __name__ == '__main__':
# Create directory
path = op.join(op.dirname(__file__), 'files')
try:
os.mkdir(path)
except OSError:
pass
# Create admin interface
admin = admin.Admin(app)
admin.add_view(fileadmin.FileAdmin(path, '/files/', name='Files'))
# Start app
app.run(debug=True)

FileAdmin是已经写好的的一个view，直接用即可：
复制代码 代码如下:
class FileAdmin(base_path, base_url, name=None, category=None, endpoint=None, url=None, verify_path=True)
base_path: 文件存放的相对路径
base_url: 文件目录的URL
FileAdmin中和ActionsMixin相关代码如下：
class FileAdmin(BaseView, ActionsMixin):
def __init__(self, base_path, base_url,
name=None, category=None, endpoint=None, url=None,
verify_path=True):
self.init_actions()
@expose('/action/', methods=('POST',))
def action_view(self):
return self.handle_action()
# Actions
@action('delete',
lazy_gettext('Delete'),
lazy_gettext('Are you sure you want to delete these files?'))
def action_delete(self, items):
if not self.can_delete:
flash(gettext('File deletion is disabled.'), 'error')
return
for path in items:
base_path, full_path, path = self._normalize_path(path)
if self.is_accessible_path(path):
try:
os.remove(full_path)
flash(gettext('File "%(name)s" was successfully deleted.', name=path))
except Exception as ex:
flash(gettext('Failed to delete file: %(name)s', name=ex), 'error')
@action('edit', lazy_gettext('Edit'))
def action_edit(self, items):
return redirect(url_for('.edit', path=items))
@action()用于wrap跟在后面的函数，这里的作用就是把参数保存起来：
def action(name, text, confirmation=None)
def wrap(f):
f._action = (name, text, confirmation)
return f
return wrap

name: action name
text: 可用于按钮名称
confirmation: 弹框确认信息
init_actions()把所有action的信息保存到ActionsMixin里面：
# 调试信息
_actions = [('delete', lu'Delete'), ('edit', lu'Edit')]
_actions_data = {'edit': (<bound method FileAdmin.action_edit of <flask_admin.contrib.fileadmin.FileAdmin object at 0x1aafc50>>, lu'Edit', None), 'delete': (<bound method FileAdmin.action_delete of <flask_admin.contrib.fileadmin.FileAdmin object at 0x1aafc50>>, lu'Delete', lu'Are you sure you want to delete these files?')}
class MyModelView(BaseModelView):
column_formatters = dict(price=lambda v, c, m, p: m.price*2)
登入後複製
或者在Jinja2模板中使用宏：
from flask.ext.admin.model.template import macro
class MyModelView(BaseModelView):
column_formatters = dict(price=macro('render_price'))
# in template
{% macro render_price(model, column) %}
{{ model.price * 2 }}
{% endmacro %}
登入後複製
回调函数模型：
def formatter(view, context, model, name):
# `view` is current administrative view
# `context` is instance of jinja2.runtime.Context
# `model` is model instance
# `name` is property name
pass
