当我按下其他表单中的按钮时，表单不显示

如何解决当我按下其他表单中的按钮时，表单不显示

在odoo13中，我创建了一个从另一个视图打开表单的按钮。 但是当我按下那个按钮时，表格没有显示。 这是我的文件： 在clients.py中，我使用了一种创建按钮的方法。 clients.py：

    from odoo import fields,models,api

class client(models.Model):
    _name = 'test13_client'
    _description = 'Clients'

    ceva = fields.Char('Email: ')
    name = fields.Char(string='Name',required=True)
    age = fields.Integer('Age: ')
    phone = fields.Integer('Phone: ')
    email = fields.Char('Email: ')
    addres = fields.Char('Addres: ')
    active = fields.Boolean(default=True)

    tickets_ids = fields.Many2many('test13_ticket',string = 'Tickets:')

    def method_name(self):
        view_id = self.env.ref('roulette.view_tickets_form').id
        context = self._context.copy()
        return {
            'name':'TicketsForm','view_type':'form','view_mode':'tree','views' : [(view_id,'form')],'res_model':'test13_ticket','view_id':view_id,'type':'ir.actions.act_window','res_id':self.id,'target':'new','context':context,}

和我想要的view.xml：

<odoo>
    <record id="action_tickets" model="ir.actions.act_window">
        <field name="name">Tickets</field>
        <field name="res_model">test13_ticket</field>
        <field name="view_mode">tree,form</field>
    </record>
    <menuitem id="menu_tickets" parent="menu_clients_app" name="Tickets" sequence="10"
              action="action_tickets"/>

    <record id="view_tickets_tree" model="ir.ui.view" >
        <field name="name">Tickets</field>
        <field name="model">test13_ticket</field>
        <field name="priority" eval="16"/>
        <field name="arch" type="xml">
            <tree>
                <field name="tickets_id"/>
            </tree>
        </field>
    </record>

    <record id="sequence_self_service" model="ir.sequence">
        <field name="name">Self Service</field>
        <field name="code">self.service</field>
        <field name="active">TRUE</field>
        <field name="prefix">ID</field>
        <field name="padding">6</field>
        <field name="number_next">1</field>
        <field name="number_increment">1</field>
    </record>

    <record id="view_tickets_form" model="ir.ui.view" >
        <field name="name">TicketsForm</field>
        <field name="model">test13_ticket</field>
        <field name="priority" eval="16"/>
        <field name="arch" type="xml">
            <form>
                <header>

                </header>
                <sheet>
                    <field name="active" invisible="1"/>
                    <widget name="web_ribbon" title="Archived" bg_color="bg-danger" attrs="{'invisible': [('active','=',True)]}"/>
                    <center>
                        <p style="font-size:50px">
                            <field name="text" readonly="1"/>
                        </p>
                    </center>
                    <group>
                        <group>
                            <field name="price" widget='monetary' options="{'currency_field': 'currency_id'}" string="Bet price:"/>
                        </group>
                        <group>
                            <field name="number_1"/>
                        </group>
                    </group>
                </sheet>
            </form>
        </field>
    </record>
</odoo>

当我按下我创建的按钮时，什么也没发生。 PS：我是编程的开始。
