如何从请求 GET 数据创建记录(表单未通过验证)
How to create a record from request GET data (form does not pass the validation)
当我尝试从“GET”请求中插入记录时,我很困惑
我会尽量解释我想做什么。
我正在创建一个应用程序来盘点资产。
我的数据库中有 3 个 table。
我有一个主要 table 叫做
注册我公司所有资产的固定资产(“ActFijo”)。
另一种调用Inventory("Inventario"),它存储每个库存的名称
和另一个电话 Inventory_detail ("Inventario_detalle"),其中存储了被统计的详细信息或资产,以验证设备或家具没有在该位置被盗.
从主要 table ("ActFijo") 我必须搜索家具或资产并将其存储在详细信息 table ("Inventario_detalle")
我很困惑,我不知道如何处理 GET 请求,然后在一个请求中执行 POST 全部操作
我是否必须在 GET 请求中分批编写代码,然后 POST?
或者我可以在 GET 请求中执行所有操作吗?
这是我目前的代码
不知道行不行,求指导
例如我的代码没有通过表单验证。
if form.is_valid():
我正在尝试打印,但我没有看到任何验证错误,它没有打印任何东西
print(form.errors)

我相信您在表单上没有看到任何验证错误,因为对于 GET 请求,您没有传递任何内容。你传递给表单的唯一东西是模型实例,你在它上面 运行 form.is_valid 这是没有意义的。您根本不需要使用表格。请改用它。
