Curd of odoo basic development (add, delete, check, change)

Introduction to the environment

• odoo edition ：odoo 13
• python edition ：3.7.3
• odoo Environment below 12 edition , Some operation methods need to add specific decorators ( Such as ：@api.multi), higher than odoo12 The version can define the operation just like the normal method .

Operation introduction

Add data ：

• Sample code ：

    @api.model
    def create(self, vals_list):
        res = super(EpidemicRecord, self).create(vals_list)
        return res

• Parameter interpretation ：
• vals_list： Dictionary type , When adding data , When the data has not been saved to the database , Data is saved here , Dictionary key Is the model field name , Dictionary value Is the field value of the model .vals_list[‘ Field name ’]= field value
• res： After successful creation , That is, the data has been saved to the database . Returned data record set .res. Field name = field value
• super( Model class name ,self). The first parameter is the model class name , Not the model name .
• Trigger this method when you click Save , Instead of triggering this method when you click Create .
• Creation does not trigger ：
  
• Triggered on save ：
  

Modifying data ：

• Sample code ：

    def write(self, vals):
        res = super(EpidemicRecord, self).write(vals)
        return res

• Parameter interpretation ：
• self： As object , Metadata of the dataset currently being modified , It can be multiple pieces of data
• vals： Is dictionary type , The data of the field we modified ,key For field name ,value Is the field value
• res： The return value is of boolean type , Modified return successfully True, Modification failure returns False
• When creating a record to save , Only execute create Method , Don't execute write Method , Just after modifying the data , Save data before execution write Method , And create Method will be executed only once when it is created .
  

Delete data ：

• Sample code ：

    def unlink(self):
        res = super(EpidemicRecord, self).unlink()
        return res

• Parameter interpretation ：
• self： Data set of current operation
• Delete all records in the current dataset , And returns a Boolean value ,true Delete successful ,false Delete failed .
• You can override this method , To achieve false deletion , Instead of deleting directly from the database .
• Batch deletion ：
  
• Single delete ：
  

Find data ：

• self.browse(ids) Method ,ids It's a list
• self.search(domain, order=‘id’, limit=1) Method ,domain Yes query criteria , limit Take before limit individual ,order sort order
