Django Regex Field letter and Numbers only
原标题:Django RegexField Letters and Numbers only

我需要一个 d沟,只接受信件和号码,而别无选择。 我曾尝试过这一点,但做了大量工作:

myfield = forms.RegexField(label=("My Label"), max_length=31, regex=r [a-zA-Z0-9] ,
        error_message = ("This value must contain only letters and numbers."),

我不赞成使用定期表达。 你们能否告诉我,我在这里做了什么错误,如何纠正?

问题回答

regex=r [a-zA-Z0-9]

页: 1

你们是否想一多封信? 然后重复使用

regex=r [a-zA-Z0-9]+

经常说几句。 请谈一下“语言表达方式”

regex=r ^[a-zA-Z0-9]+$ ,

只接受信函和编号,至少需要一个文号

你们的意思是“做不到工作”? 你们是否更具体?

我可以发现的“error”是,它只接受一个单一的果园。 您在<代码>regex的论点中再次出现重复。 结尾处添加<代码>*或+(详见python sre模块文件。
