Odoo：如何检查模块是否已安装？

Question

I want to inherit form view in XML to set invisible some fields but sometime I will not install that module.

How to solve this?

Answer 1

You can add this code to the model of the view you want to modify:

@api.depends()
def _compute_module_x_installed(self):
    for record in self:
        module = self.env['ir.module.module'].search([
            ('name', '=', 'the_module_name')
        ])
        if module and module.state == 'installed':
            record.update({
                'module_x_installed': True,
            })

module_x_installed = fields.Boolean(
    compute='_compute_module_x_installed',
    string='Is X installed?',
)

That way you'll have a field which will indicate you whether the module is installed or not.

Answer 2

You can also achieve the current status of the module with the help of ir_module_module database table.

ir.module.module model Odoo create a new database table which named is ir_module_module where we can search the status of our module through SQL Query using Pgadmin Tools

select state from ir_module_module where name='Your_module_name(technical_name)';

If we get the result is ' installed ' in out query it means our module is installed in our database.
