dashboard添加可编辑字段

在tables.py中添加如下代码：

class UpdateRow(tables.Row):
    ajax = True

    def get_data(self, request, instance_id):
        project_info = api.nova.server_get(request, instance_id)

        return project_info

class UpdateCell(tables.UpdateAction):
    def allowed(self, request, instance, cell):
        policy_rule = (("identity", "identity:update_project"),)
        return True
    def update_cell(self, request, datum, instance_id,cell_name, new_cell_value):
     # inline update project info
        instance_obj = datum
         # updating changed value by new value
        setattr(instance_obj, cell_name, new_cell_value)
        api.nova.server_update(request,instance_id,name=instance_obj.name) //from openstack_dashboard import api
        return True

在定义字段的部分做如下修改：

name = tables.Column("name", verbose_name=_("Name"),form_field=forms.CharField(max_length=64),update_action=UpdateCell)   //form_field也是新加的，同时要：from horizon import forms

class Meta:类中新加

row_class = UpdateRow  //引用上面的UpdateRow
