Question

如何在python中调用另一个函数内的函数（不在另一个函数中编写函数）。

class OrderDetails(Document):
  def validate(self):

    # Remove duplicates
    found={}
    #global nfound
    i=-1
    #msgprint(_("00000"))
    #msgprint(_(found))
    #frappe.errprint(found)
    for selected in self.adding:
        i=i+1
        if selected.selected in found:
            #frappe.throw(_("Duplicate {0}").format(i))
            self.adding[found[selected.selected]].quantity = self.adding[found[selected.selected]].quantity + self.adding[i].quantity
            self.adding[i].quantity = 0
            self.adding[i].selected = 'product-04'
            return edit_quantity_on_hand(selected.selected)

        if selected.selected not in found:
            found[selected.selected] = i
            return edit_quantity_on_hand(selected.selected)


    q='product-04'
    frappe.db.sql("DELETE FROM `tabAdd to Order` WHERE selected = (%s);" ,(q))



  def edit_quantity_on_hand(data):
    quantity_on_hand_f = frappe.db.get_value("Product Details", data, "quantity_on_hand")
    product_name_f = frappe.db.get_value("Product Details", data, "product_name")
    if quantity_on_hand_f - self.adding[found[data]].quantity < 0:
        frappe.throw(_("Quantity on Hand {0} is less than orderd amount ").format(quantity_on_hand_f))

    else :
        quantity_on_hand_f = quantity_on_hand_f - self.adding[found[data]].quantity
        frappe.db.sql("Update `tabProduct Details` Set quantity_on_hand = (%s) Where product_name =(%s); ",(quantity_on_hand_f, product_name_f))

如何使用args在“validate（）”函数中调用“edit_quantity_on_hand（）”？

Answer 1

由于您尚未将edit_quantity_on_hand指定为静态方法，因此需要将其作为具有self.edit_quantity_on_hand的实例方法引用。此外，该函数需要一个包含实例本身的参数 - 它具有此功能，但此时它是data。请改用def edit_quantity_on_hand(self, data):。

有帮助吗？

def execute(func_name, *args, **kwargs):
    return func_name(*args, **kwargs)

Python在另一个函数中调用一个函数
