[英]TypeError: int() argument must be a string, a bytes-like object or a number, not 'TextInput'
I am developing a Kivy password generator.我正在开发一个 Kivy 密码生成器。 The user is required to input a number (digit) into the app for password generate depending on how many characters are intended.
用户需要在应用程序中输入一个数字(数字)以生成密码,具体取决于预期的字符数。 Then, the app will generate a random character from the randint, finally, the output will be displayed into the output entry for a copy to the click board.
然后,应用程序会从 randint 中生成一个随机字符,最后,output 将显示到 output 条目中,以便复制到点击板。 Following are my code:

How to resolve?如何解决?
Try changing pw_length in your password()
function to:尝试将
password()
function 中的 pw_length 更改为:
pw_length = int(self.root.ids.input_entry.text or 0)
input_entry is a TextInput which can't be converted to an int. input_entry 是无法转换为 int 的 TextInput。 I think you want to convert its value (
input_entry.text
) to an int, not the widget itself.我认为您想将其值 (
input_entry.text
) 转换为 int,而不是小部件本身。 To do that, change the pw_length =...
line in password()
method as above.为此,如上更改
password()
方法中的pw_length =...
行。
When you use something like self.root.ids.some_name
(or, self.ids.some_name
) you are supposed to access aweak reference of the named ( some_name
) widget from root
(or, some class).当您使用类似
self.root.ids.some_name
(或self.ids.some_name
)的东西时,您应该从root
(或某个类)访问命名( some_name
)小部件的弱引用。
Now to get an attr.现在得到一个attr。 of that proxy widget you can go as usual using '.'
该代理小部件的您可以像往常一样使用“。” go。 syntax ie like
self.root.ids.some_name.prop
(or, self.ids.some_name.prop
).语法即
self.root.ids.some_name.prop
(或self.ids.some_name.prop
)。
Here, self.root.ids.output_entry
is a TextInput
instance.这里,
self.root.ids.output_entry
是一个TextInput
实例。 So to access any of its properties you can do something like, self.root.ids.output_entry.prop_name
.因此,要访问它的任何属性,您可以执行类似
self.root.ids.output_entry.prop_name
的操作。 With this I modified password
method as,有了这个,我修改了
password
方法,
def password(self):
self.root.ids.output_entry.text = ''
input_text = self.root.ids.input_entry.text
# Bellow you will handle user-input. You can use try-except or if-else or whatever that suits. I just implement a simple one.
if input_text: # Means non-empty string.
pw_length = int(input_text)
else: # Raise Error or warn user via a message.
pw_length = 0
my_password = ''
for x in range(pw_length):
my_password += chr(randint(33, 126))
self.root.ids.output_entry.text = my_password
Don't forget to apply the required changes (as described above) wherever necessary.不要忘记在必要时应用所需的更改(如上所述)。
first the text field has to be limited to support only integers by adding the input_filter: "int"
首先,必须通过添加
input_filter: "int"
将文本字段限制为仅支持整数
TextInput:
id: input_entry
text: ''
multiline: False
font_family: 'Helvatica'
font_size: 24
pos_hint: {'x': .8, 'y':4.5}
size_hint: (2, .4)
halign: "center"
focus: True
color: 'black'
input_filter: "int"
