Below is my code snippet that deletes a record from a table.
async deleteTodo(id: number) {
this.todosRepository.delete(id);
}
I am trying to figure out how to handle messages during the deletion process.
For instance, if a user provides an identifier for a record that doesn't exist, I would like to display the message "record not found." Similarly, I want to handle any errors that occur during the deletion process.
.delete function does not include an entity existence check in the database.
To verify if a record exists, you can use the select method and then check the result.
For instance:
const data = await this.todosRepository
.createQueryBuilder("todos")
.where('todos.id= :todelid', { id: todelid })
.getOne();
if (data.length == 0) {
return "No record found.";
} else {
return "Record found.";
}
