A DocField defines a property (or a field) of a DocType. You can define the column name, label, datatype and more for DocFields. For instance, a ToDo doctype has fields description, status and priority. These ultimately become columns in the database table tabToDo.


The DocField stores meta-data about the field. Some of them are described below.

        "label": "Description",     // the value shown to the user (Form, Print, etc)
        "fieldname": "description", // the property name we refer in code, also the column name
        "fieldtype": "Text Editor", // the fieldtype which also decides how to store this value
        "reqd": 1                   // whether this field is mandatory
        "label": "Status",
        "fieldname": "status",
        "fieldtype": "Select",
        "options": [
        "label": "Priority",
        "fieldname": "priority",
        "fieldtype": "Select",
        "options": [                // list of options for select
        "default": "Low"            // the default value to be set
        "label": "Completed By",
        "fieldname": "completed_by",
        "fieldtype": "Link",
        "options": "User",
        "depends_on": "eval: doc.status == 'Closed'", // the condition on which this field's display depends
        "collapsible": 1,
        "collapsible_depends_on": "eval:doc.status!='Closed'", // determines if a Section Break field is collapsible
        "fieldname": "sb_details",
        "fieldtype": "Section Break",
        "label": "Details"
        "fieldname": "amount",
        "fieldtype": "Currency", // Currency field
        "label": "Amount",
        "non_negative": 1, // determines whether this field value can be negative
        "options": "INR",

Similar to the depends_on property which determines whether a field will be displayed or not, in Version 12 we have introduced two new properties:

  • mandatory_depends_on: If this condition is satisfied, the field will be mandatory.
  • read_only_depends_on: If this condition is satisfied, the field will be read only.

Frappe comes with more than 30 different fieldtypes out-of-the-box. These fieldtypes serve a variety of use-cases. Learn more about Fieldtypes.
