odoo controller 继承

方式一：

继承基类，直接重写方法

from odoo.addons.web.controllers.main import Export

class PsExport(Export):
    @http.route('/web/export/get_fields', type='json', auth="user")

 def get_fields(self, model, prefix='', parent_name= '', import_compat=True, parent_field_type=None, parent_field= None, exclude=None): 

 return XXX

方式二：

Monkey Patch – – python运行时动态改变类的方法

例1:

from odoo.addons.web.controllers.pivot import TableExporter

@http.route('/web/pivot/export_xls', type='http', auth="user")
def export_xls(self, data, token):
    return XXX

TableExporter.export_xls = export_xls

例2:

fields_view_get_origin = models.BaseModel.fields_view_get

@api.model
def fields_view_get(self, view_id=None, view_type='form', toolbar=False, submenu=False):
    res = fields_view_get_origin(self, view_id=view_id, view_type=view_type, toolbar=toolbar, submenu=submenu)
    if view_type == 'form' and self.env['ir.module.module'].search_count(
            [('name', '=', 'rul'), ('state', '=', 'installed')]):
        base_model = res.get('base_model')
 fields_ids = self.env['ir.model'].search([('model', '=', base_model)])
        doc = etree.XML(res['arch'])
        for fields_id in fields_ids.fields_ids:
            xpath = "//field[@name='%s']" % fields_id.name
            if doc.xpath(xpath):
                node = doc.xpath(xpath)[0]
                node.set('required', '1')
                setup_modifiers(node, res['fields'][fields_id.name])
        res['arch'] = etree.tostring(doc, encoding='unicode')
    return res

models.BaseModel.fields_view_get = fields_view_get
