Customize Form - Links Table

The links table in the Customize Form Doctype is used to define relationships between the current Doctype and other Doctypes. Each row in the links table represents a link or relationship. Here is an explanation of the individual fields in the links table and their usage:

1. link_doctype

• Description: Specifies the target Doctype to which the link is created.
• Use: Define the Doctype that the current Doctype should reference or interact with. For example, linking a Sales Order to a Customer Doctype.

2. link_fieldname

• Description: The fieldname in the current Doctype used for the link.
• Use: Identifies the field in the current Doctype that establishes the link to the specified Doctype. For example, a customer field in a Sales Order links to the Customer Doctype.

3. group

• Description: Categorizes the link under a specific group.
• Use: Organize links into groups for better readability or functionality, especially when dealing with complex Doctypes.

4. hidden

• Description: Indicates whether the link should be hidden from the user interface.
• Use: Hide links that are not directly relevant to the user but are used in backend processes or automation.

5. idx

• Description: Specifies the sequence number of the link in the list.
• Use: Controls the order in which links are displayed in the links table.

Examples of Usage:

1. Linking a Sales Invoice to a Customer:

   • link_doctype: Customer
   • link_fieldname: customer
   • Use: Establish a relationship where a Sales Invoice references the Customer Doctype.

2. Linking a Task to a Project:

   • link_doctype: Project
   • link_fieldname: project
   • Use: Ensure every Task is associated with a specific Project.

3. Hidden Link for Backend Use:

   • link_doctype: User
   • link_fieldname: owner
   • hidden: Checked
   • Use: Track the user who created the document without displaying it to others.

4. Grouped Links for Better Organization:

   • link_doctype: Item
   • link_fieldname: item_code
   • group: Inventory
   • Use: Group item-related links together in the interface.

These fields allow you to define and manage the relationships between Doctypes, enabling smooth data integration and automation across modules.
