Xadmin-自定義字段支持實時編輯

# 需要顯示的列
list_display = ['fbm_display']

# 實時編輯功能
    list_editable = ['reason_one', 'low_price', 'artificial_confirm_stock_no_fbn'] 

# 因為這個字段后期要加一些顯示的邏輯，所以需要自定義，但是又希望能支持實時編輯 

def fbm_display(self, row): 

　　return row.artificial_confirm_stock_no_fbn 
 
fbm_display.short_description = '補FBM'

1. 修改models

class Goods(models.Model):
    '''
    商品表
    '''
   
    artificial_confirm_stock_no_fbn = models.IntegerField(verbose_name='人工海外補貨', default=-1)
   
# 在表中添加一個函數，函數名要跟自定義字段的名字相同
    def fbm_display(self):
        return 'artificial_confirm_stock_no_fbn'

2 修改 xadmin/util.py

def lookup_field(name, obj, model_admin=None):
    opts = obj._meta

    try:
        f = opts.get_field(name)
    except models.FieldDoesNotExist:
        # For non-field values, the value is either a method, property or
        # returned via a callable.
        if callable(name):
            attr = name
            value = attr(obj)
        elif (
                model_admin is not None
                and hasattr(model_admin, name)
                and name not in ('__str__', '__unicode__')
        ):
            attr = getattr(model_admin, name)
            value = attr(obj)
        else:
            if is_rel_field(name, obj):
                parts = name.split("__")
                rel_name, sub_rel_name = parts[0], "__".join(parts[1:])
                rel_obj = getattr(obj, rel_name)
                if rel_obj is not None:
                    return lookup_field(sub_rel_name, rel_obj, model_admin)
            attr = getattr(obj, name)
            if callable(attr):
                value = attr()
            else:
                value = attr
        f = None
        # 目的是為了傳回字段
        if hasattr(obj, name):
            field = getattr(obj, name)()
            opts = obj._meta
            f = opts.get_field(field)
        # 添加完畢
    else:
        attr = None
        value = getattr(obj, name)
    return f, attr, value

 

 

3.修改 xadmin/plugins/editable.py

  def result_item(self, item, obj, field_name, row):
        # 將list_display中的自定義字段名 跟 list_editable中的字段名綁定
        model_fields = [f.name for f in self.opts.fields]
        if hasattr(self.model, field_name) and field_name not in model_fields:
            field_name = getattr(self.model, field_name)(self)
        # 添加完畢
        if self.list_editable and item.field and item.field.editable and (field_name in self.list_editable):

            pk = getattr(obj, obj._meta.pk.attname)
            field_label = label_for_field(field_name, obj,
                                          model_admin=self.admin_view,
                                          return_attr=False
                                          )

            item.wraps.insert(0, '<span class="editable-field">%s</span>')
            item.btns.append((
                                     '<a class="editable-handler" title="%s" data-editable-field="%s" data-editable-loadurl="%s">' +
                                     '<i class="fa fa-edit"></i></a>') %
                             (_(u"Enter %s") % field_label, field_name,
                              self.admin_view.model_admin_url('patch', pk) + '?fields=' + field_name))

            if field_name not in self.editable_need_fields:
                self.editable_need_fields[field_name] = item.field

        return item
