form.validate_on_submit()和form.validate()之间的区别 [英] Difference between `form.validate_on_submit()` and `form.validate()`
问题描述
form.validate_on_submit()
和form.validate()
有什么区别?
在 Flask WTF文档中,作者使用了form.validate_on_submit()
.该代码有效.当我用form.validate()
替换form.validate_on_submit()
时,我发现行为没有区别.我在源代码中找不到form.validate_on_submit()
,但是我设法找到form.validate()
代码.
In the Flask WTF docs, the author uses form.validate_on_submit()
. The code works. When I substitute form.validate_on_submit()
with form.validate()
, I see no difference in behavior. I couldn't find form.validate_on_submit()
in the source, but I managed to find form.validate()
code.
推荐答案
validate_on_submit()
是is_submitted() and validate()
的快捷方式.
来自源代码,行89,如果提交的表单是活动请求,并且方法是POST,PUT,PATCH或DELETE,则is_submitted()
返回True.
From the source code, line 89, is_submitted()
returns True if the form submitted is an active request and the method is POST, PUT, PATCH, or DELETE.
通常来说,它用于路由可以接受GET和POST方法并且您只想对POST请求进行验证的情况.
Generally speaking, it is used when a route can accept both GET and POST methods and you want to validate only on a POST request.
