i want to set default value for one2many tree view here are my tables

class EstimationModel(models.Model):
        employee_id = fields.Many2one('res.users',string="Assign to",tracking=1)
        project_detail_ids = fields.One2many('project.details', 'estimation_id', string="Project Details")
        technology_id = fields.Many2one('technology.info',string="Technology Name",tracking=1)
        tag_ids = fields.Many2many('project.tag', string="Project Tags",store=True)
 

class ProjectDetails(models.Model):
    module_name = fields.Char(string="Module Name")
    hours = fields.Float(string="hours",related='task_id.hours',readonly=False)
    task_notes = fields.Text(string="Notes",related='task_id.task_notes',readonly=False)
    task_id = fields.Many2one('add.task', string='Module Name..')
    total_hours = fields.Float(string="Total hours",tracking=1)
    estimation_id = fields.Many2one('estimation.info', string="estimation")
    name = fields.Text(string='Notes', required=False)
    category_id = fields.Many2one('project.category',string='Category Name')

 
class AddTask(models.Model):
    technology_id = fields.Many2one('technology.info',string="Technology Name",tracking=1)
    tag_ids = fields.Many2many('project.tag', string="Project Tags")
    module_name = fields.Char(string="Module Name")
    hours = fields.Float(string="hours")
    total_hours = fields.Float(string="Total hours",tracking=1)
    estimation_id = fields.Many2one('estimation.info', string="estimation")
    name = fields.Text(string='Notes', required=False)
    notes = fields.Char(string='Add Notes')
    task_notes = fields.Text(string='Add Notes')

To set a default value for the project_detail_ids field in the EstimationModel model, you can use the default attribute in the field definition. For example, if you want to set the default value of project_detail_ids to be all the records in the AddTask model that have a technology_id value of 1, you can use the following code:

class EstimationModel(models.Model):
    # existing code here
    project_detail_ids = fields.One2many(
        'project.details',
        'estimation_id',
        string="Project Details",
        default=lambda self: self.env['project.details'].search([('task_id.technology_id', '=', 1)])
    )

This will set the default value of the project_detail_ids field to be all the project.details records that have a task_id value with a technology_id value of 1.

If you want to set the default value of the project_detail_ids field to be all the records in the AddTask model, you can use the following code instead:

class EstimationModel(models.Model):
    # existing code here
    project_detail_ids = fields.One2many(
        'project.details',
        'estimation_id',
        string="Project Details",
        default=lambda self: self.env['add.task'].search([])
    )

This will set the default value of the project_detail_ids field to be all the add.task records in the database.

Note that in both cases, the default value is a lambda function that searches for the relevant records in the database. This allows the default value to be dynamic and depend on the current context. For example,
