        For example, if you want to show price multiplied by
        two, you can do something like this::

            class MyModelView(BaseModelView):
                column_formatters = dict(price=lambda v, c, m, p: m.price*2)

        or using Jinja2 `macro` in template::

            from flask_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 %}

        The Callback function has the prototype::

            def formatter(view, context, model, name):
                # `view` is current administrative view
                # `context` is instance of jinja2.runtime.Context
                # `model` is model instance

        Dictionary of value type formatters to be used in the list view.

        By default, three types are formatted:

        1. ``None`` will be displayed as an empty string
        2. ``bool`` will be displayed as a checkmark if it is ``True``
        3. ``list`` will be joined using ‘, ‘

        If you don‘t like the default behavior and don‘t want any type formatters
        applied, just override this property with an empty dictionary::

            class MyModelView(BaseModelView):
                column_type_formatters = dict()

        If you want to display `NULL` instead of an empty string, you can do
        something like this. Also comes with bonus `date` formatter::

            from datetime import date
            from flask_admin.model import typefmt

            def date_format(view, value):
                return value.strftime(‘%d.%m.%Y‘)

            MY_DEFAULT_FORMATTERS = dict(typefmt.BASE_FORMATTERS)

                column_type_formatters = MY_DEFAULT_FORMATTERS

        Type formatters have lower priority than list column formatters.

                # `view` is current administrative view

        如果要显式指定排序时要使用的字段/列,可以使用元组:
            class MyModelView(BaseModelView):
                column_sortable_list = (‘name‘, (‘user‘, ‘user.username‘))

                    ‘name‘, (‘user‘, (‘user.first_name‘, ‘user.last_name‘)))

        使用SQLAlchemy模型时,可以使用模型属性而不是字符串: :
            class MyModelView(BaseModelView):
                column_sortable_list = (‘name‘, (‘user‘, User.username))

        You can use tuple to control ascending descending order. In following example, items
        will be sorted in descending order::

            class MyModelView(BaseModelView):
                column_default_sort = (‘user‘, True)

        If you want to sort by more than one column,
        you can pass a list of tuples::

                    }
                }
    
        Or with SQLAlchemy backend like this::
    
            class MyModelView(BaseModelView):
                form_ajax_refs = {
                    ‘user‘: QueryAjaxModelLoader(‘user‘, db.session, User, fields=[‘email‘], page_size=10)
                }
    
        If you need custom loading functionality, you can implement your custom loading behavior
        in your `AjaxModelLoader` class.

        List of rendering rules for model creation form.
    
        This property changed default form rendering behavior and makes possible to rearrange order
        of rendered fields, add some text between fields, group them, etc. If not set, will use
        default Flask-Admin form rendering logic.
    
        Here‘s simple example which illustrates how to use::
    
            from flask_admin.form import rules
    
            class MyModelView(ModelView):
                form_rules = [
                    # Define field set with header text and four fields
                    rules.FieldSet((‘first_name‘, ‘last_name‘, ‘email‘, ‘phone‘), ‘User‘),
                    # ... and it is just shortcut for:
                    rules.Header(‘User‘),
                    rules.Field(‘first_name‘),
                    rules.Field(‘last_name‘),
                    # ...
                    # It is possible to create custom rule blocks:
                    MyBlock(‘Hello World‘),
                    # It is possible to call macros from current context
                    rules.Macro(‘my_macro‘, foobar=‘baz‘)
