减少Flask-Admin中列的大小

Question

有没有办法限制ModelView列的大小(长度/宽度)？我正在使用WYSIWYG编辑器,这会创建非常长的文本,因此使得ModelView的列非常长.

这是它的样子的图片.查看最后一列的右侧.它甚至比屏幕截图所能处理的还要长.

Answer 1

不显示列(通过排除):

class MyView(ModelView):

    column_exclude_list = ('description')

不显示列(通过包含):

class MyView(ModelView):

    column_list = ('rating', 'category_id', 'year', 'stock', 'image')   

重新格式化列:

class MyView(ModelView):

     def _description_formatter(view, context, model, name):
        # Format your string here e.g show first 20 characters
        # can return any valid HTML e.g. a link to another view to show the detail or a popup window
        return model.description[:20]

    column_formatters = {
        'description': _description_formatter,
    }
