Introduction
Enterprise
This slide discusses how to delete or clear records in an Odoo
17 one2many field. We'll achieve this by adding a button
named "Delete Records." Clicking this button will delete all
associated one2many records.

Enterprise
Add button
● To add the button, I've included the following code in
the XML view
<form>
<header>
<button string="Delete Record" type="object"
name="action_delete_record"/>
</header>
</form>

Enterprise
Define the button function
● In the corresponding python file define the function as
follows
def action_delete_record(self):
self.line_ids = [Command.unlink(line.id)
for line in self.line_ids]

Enterprise
Now upgrade the module and on clicking the button all the
one2many records will be deleted
We can also do this by making use of unlink method
In this case change the function as follows
def action_delete_record(self):
self.line_ids.unlink()

Wizards are very useful for creating a good user experience. In all businesses, interactive sessions are most beneficial. To improve the user experience, wizards in Odoo provide an interactive session. For creating wizards, we can use transient models or abstract models. This gives features of a model class except the data storing. Transient and abstract models have permanent database persistence. For them, database tables are made, and the records in such tables are kept until they are specifically erased.

Lab Steps STEP 1: Login Form 1. In order to do this lab, we need to assign a primary key to the tblUserLogin table. This will allow us to modify the user login table from our Manage Users form that we will create later. Go to Windows Explorer and open the PayrollSystem_DB.accdb. Set the UserID as the Primary key and save the table. Close the database. 2. Open Microsoft Visual Studio.NET. 3. Click the ASP.NET website named PayrollSystem to open it. 4. Create a new Web form named frmLogin. 5. Add the ACIT logo to the top of the frmLogin page. Do not hyperlink the logo. 6. Under the login controls, you will see Login. Drop the Login control onto the form. Set the properties of the login control as follows: Property Value DestinationPageUrl frmMain.aspx TitleText Please enter your UserName and Password in order to log in to the system. 7. Highlight everything in the form, then click Format, Justify, Center. Save your work. 8. Go to the Solution Explorer, right-click on frmLogin, and left-click on Set As Start Page. Then run the website to check if the Web form appears correctly. If you receive an error, add the following code to the web.config file right above the </configuration> line: <appSettings> <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" /> </appSettings> STEP 2: Login Check 9. Create a new DataSet called dsUser. Use the table tblUserLogin as the database table for this dataset. Do this in the same way that you added datasets in the previous labs. 10. Open the clsDataLayer and add the following function: // This function verifies a user in the tblUser table public static dsUser VerifyUser(string Database, string UserName, string UserPassword) { // Add your comments here dsUser DS; OleDbConnection sqlConn; OleDbDataAdapter sqlDA; // Add your comments here sqlConn = new OleDbConnection("PROVIDER=Microsoft.ACE.OLEDB.12.0;" + "Data Source=" + Database); // Add your comments here sqlDA = new OleDbDataAdapter("Select SecurityLevel from tblUserLogin " + "where UserName like '" + UserName + "' " + "and UserPassword like '" + UserPassword + "'", sqlConn); // Add your comments here DS = new dsUser(); // Add your comments here sqlDA.Fill(DS.tblUserLogin); // Add your comments here return DS; } 11. Double-click on the login control that you added. Add the following code to the login control Authenticate event handler: // Add your comments here dsUser dsUserLogin; // Add your comments here string SecurityLevel; // Add your comments here dsUserLogin = clsDataLayer.VerifyUser(Server.MapPath("PayrollSystem_DB.accdb"), Login1.UserName, Login1.Password); // Add your comments here if (dsUserLogin.tblUserLogin.Count < 1) { e.Authenticated = false; return; } // Add your comments here SecurityLevel = dsUserLogin.tblUserLogin[0].SecurityLevel.ToString(); // Add your comments here switch (SecurityLevel) { case "A": // Add your comments here e.Authenticated = true; Session["SecurityLevel"] = "A"; break; case "U": // Add your comments ...
