How do I make a text field accept only numeric values? If I press a letter or a symbol, the text field should not be filled, it should only allow numbers.
Is there a rails way to do this?

You can use the <input> tag with attribute type='number'. This input field allows only numerical values. You can also specify the minimum value and maximum value that should be accepted by this field.
To limit an HTML input box to accept numeric input, use the <input type="number">. With this, you will get a numeric input field. After limiting the input box to number, if a user enters text and press submit button, then the following can be seen “Please enter a number.”
Use number_field_tag, this will generate a HTML5 number field
