odoo V10开发文档（第二章：高级视图）

tree view

decoration-{ name }
可以根据值来改变字段的显示，$name可为bf (font-weight: bold), it (font-style: italic)或其他bootstrap样式如danger, info, muted, primary, success,warning

<tree string="Idea Categories" decoration-info="state=='draft'"
    decoration-danger="state=='trashed'">
    <field name="name"/>
    <field name="state"/>
</tree>

editable
取值为top或bottom,不需要跳转到form可以直接编辑字段

日历视图

日历视图的属性：color,date_start,date_stop

#models.py 更改
from datetime import timedelta
end_date = fields.Date(string="End Date", store=True,
        compute='_get_end_date', inverse='_set_end_date')
@api.depends('start_date', 'duration')
def _get_end_date(self):
    for r in self:
        if not (r.start_date and r.duration):
            r.end_date = r.start_date
            continue

        # Add duration to start_date, but: Monday + 5 days = Saturday, so
        # subtract one second to get on Friday instead
        start = fields.Datetime.from_string(r.start_date)
        duration = timedelta(days=r.duration, seconds=-1)
        r.end_date = start + duration

def _set_end_date(self):
    for r in self:
        if not (r.start_date and r.end_date):
            continue

        # Compute the difference between dates, but: Friday - Monday = 4 days,
        # so add one day to get 5 days instead
        start_date = fields.Datetime.from_string(r.start_date)
        end_date = fields.Datetime.from_string(r.end_date)
        r.duration = (end_date - start_date).days + 1
    
#view.xml 更新
 <!-- calendar view -->
<record model="ir.ui.view" id="session_calendar_view">
    <field name="name">session.calendar</field>
    <field name="model">openacademy.session</field>
    <field name="arch" type="xml">
        <calendar string="Session Calendar" date_start="start_date"
                  date_stop="end_date"
                  color="instructor_id">
            <field name="name"/>
        </calendar>
    </field>
</record>
<record model="ir.actions.act_window" id="session_list_action">
    <field name="name">Sessions</field>
    <field name="res_model">openacademy.session</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form,calendar</field>
</record>

重启更新后session列表多了一个日历视图模式，视图中对session日期包含的日期会自动高亮区分

搜索视图

搜索视图的field元素包含一个domain表达式，也可用filter_domain属性来定义，在表达式内self代表用户输入值；
视图还可定义filter元素设定默认搜索条件，该元素需包含domain和context属性中的一个，domain属性为当前搜索添加限定规则，context可通过group_by来对字段进行分组
例：添加一个筛选按钮用于选择当前用户负责的课程，一个分组按钮将课程按负责人分组

#views.xml 修改
<record model="ir.ui.view" id="course_search_view">
    <field name="name">courses.search</field>
    <field name="model">openacademy.courses</field>
    <field name="arch" type="xml">
        <search>
            <field name="name"/>
            <field name="description"/>
            <filter name="my_courses" string="My Courses"
                    domain="[('responsible_id', '=', uid)]"/>
            <group string="Group By">
                <filter name="by_responsible" string="Responsible"
                        context="{'group_by': 'responsible_id'}"/>
            </group>
        </search>
    </field>
</record>

<record model="ir.actions.act_window" id="course_list_action">
    <field name="name">Courses</field>
    <field name="res_model">openacademy.courses</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form</field>
    <field name="context" eval="{'search_default_my_courses': 1}"/>
    <field name="help" type="html">
        <p class="oe_view_nocontent_create">Create the first course
        </p>
    </field>
</record>

<menuitem id="course_menu" name="课程"
                  parent="openacademy_menu"
                  action="course_list_action"/>

图表视图

1.图表视图可将数据进行聚合显示，使用graph元素来定义，一共有4种显示模式，Bar- 柱形图、Line -线状图、pie -扇形图
2.视图的field可以通过type属性来定义数据展现,row指数据总计（默认）、measure指数据估值

示例：将课程的参与人数用图表展示

#models.py
attendees_count = fields.Integer(
        string="Attendees count", compute='_get_attendees_count', store=True)
@api.depends('attendee_ids')
    def _get_attendees_count(self):
        for r in self:
            r.attendees_count = len(r.attendee_ids)

#views.xml
<record model="ir.ui.view" id="openacademy_session_graph_view">
    <field name="name">openacademy.session.graph</field>
    <field name="model">openacademy.session</field>
    <field name="arch" type="xml">
        <graph string="Participations by Courses">
            <field name="course_id"/>
            <field name="attendees_count" type="measure"/>
        </graph>
    </field>
</record>
 <record model="ir.actions.act_window" id="session_list_action">
    <field name="name">Sessions</field>
    <field name="res_model">openacademy.session</field>
    <field name="view_type">form</field>
    <field name="view_mode">tree,form,calendar,gantt,graph</field>
</record>

kanban视图

kanban视图用于显示待力任务，生产工序等，以卡片的形式进行显示，根元素是kanban

添加一个按课程分组的session kanban

#models.py添加
color = fields.Integer()

#views.xml添加
<record model="ir.ui.view" id="view_openacad_session_kanban">
    <field name="name">openacad.session.kanban</field>
    <field name="model">openacademy.session</field>
    <field name="arch" type="xml">
        <kanban default_group_by="course_id">
            <field name="color"/>
            <templates>
                <t t-name="kanban-box">
