python - 如何修改数据库管理器中的重复表单？

Question

我想在这个表单中添加一些可以从 Odoo 中的数据库管理器访问的其他字段

数据被发送到这个 Controller :

@http.route('/web/database/duplicate', type='http', auth="none", methods=['POST'], csrf=False)
def duplicate(self, master_pwd, name, new_name):
    try:
        if not re.match(DBNAME_PATTERN, new_name):
            raise Exception(_('Invalid database name. Only alphanumerical characters, underscore, hyphen and dot are allowed.'))
        dispatch_rpc('db', 'duplicate_database', [master_pwd, name, new_name])
        return http.local_redirect('/web/database/manager')
    except Exception as e:
        error = "Database duplication error: %s" % (str(e) or repr(e))
        return self._render_template(error=error)

但是表单是纯html，所以我不能继承和修改任何模板:

<!-- Duplicate DB -->
<div class="modal fade o_database_duplicate" role="dialog">
    <div class="modal-dialog">
        <div class="modal-content">
        <div class="modal-header">
        <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">&times;</span></button>
        <h4 class="modal-title">Duplicate Database</h4>
        </div>
        <form id="form-duplicate-db" role="form" action="/web/database/duplicate" method="post">
            <div class="modal-body">
            {{ master_input() }}
            <div class="form-group">
                <label for="name" class="control-label">Database Name</label>
                <input id="name" type="text" name="name" class="form-control" required="required" readonly="readonly"/>
            </div>
            <div class="form-group">
                <label for="new_name" class="control-label">New Name</label>
                <input id="new_name" type="text" name="new_name" class="form-control" required="required" pattern="{{ pattern }}" title="Only alphanumerical characters, underscore, hyphen and dot are allowed"/>
            </div>
            </div>
            <div class="modal-footer">
            <input type="submit" value="Continue" class="btn btn-primary pull-right"/>
            </div>
        </form>
        </div>
    </div>
</div>

我找到了呈现此 html 的 python 代码

class Database(http.Controller):

    def _render_template(self, **d):
        d.setdefault('manage',True)
        d['insecure'] = odoo.tools.config.verify_admin_password('admin')
        d['list_db'] = odoo.tools.config['list_db']
        d['langs'] = odoo.service.db.exp_list_lang()
        d['countries'] = odoo.service.db.exp_list_countries()
        d['pattern'] = DBNAME_PATTERN
        # databases list
        d['databases'] = []
        try:
            d['databases'] = http.db_list()
            d['incompatible_databases'] = odoo.service.db.list_db_incompatible(d['databases'])
        except odoo.exceptions.AccessDenied:
            monodb = db_monodb()
            if monodb:
                d['databases'] = [monodb]
        return env.get_template("database_manager.html").render(d)

我是否应该修改此代码以使用其他模板？或者有其他更合适的解决方案吗？

直接在web模块中修改原来的代码是唯一的办法吗？有没有办法通过继承 web 模块来改变所有这些行为？

Answer 1

当然，您可以通过自定义模块来完成。首先您必须根据需要定义自己的 html 模板，然后必须重写呈现 html 文件的 Controller 。

您可以引用以下代码重写 Controller 。

from odoo.addons.web.controllers.main import Database  # importing base controller class

class MyDatabase(Database):
    def _render_template(self, **d):
       d.setdefault('manage',True)
       d['insecure'] = odoo.tools.config.verify_admin_password('admin')
       d['list_db'] = odoo.tools.config['list_db']
       d['langs'] = odoo.service.db.exp_list_lang()
       d['countries'] = odoo.service.db.exp_list_countries()
       d['pattern'] = DBNAME_PATTERN
       #additional parameters if any
       d['databases'] = []
       try:
           d['databases'] = http.db_list()
           d['incompatible_databases'] = odoo.service.db.list_db_incompatible(d['databases'])
       except odoo.exceptions.AccessDenied:
           monodb = db_monodb()
           if monodb:
               d['databases'] = [monodb]

       return env.get_template("your_modified_template.html").render(d)  #render your modified html template.
