Rails validating full_name

由 江枫思渺然 提交于 2019-12-03 07:38:25
问题 Hey... how would you validate a full_name field (name surname). 回答1: Consider names like: Ms. Jan Levinson-Gould Dr. Martin Luther King, Jr. Brett d'Arras-d'Haudracey Brüno Instead of validating the characters that are there, you might just want to ensure some set of characters is not present. For example: class User < ActiveRecord::Base validates_format_of :full_name, :with => /\A[^0-9`!@#\$%\^&*+_=]+\z/ # add any other characters you'd like to disallow inside the [ brackets ] #

Why is moment.js allowing date with one digit year when using strict parsing?

由 女生的网名这么多〃 提交于 2019-12-01 23:42:05
I am using moment.js to parse a date. http://momentjs.com/docs/#/parsing/string-format/ This is to validate and convert the date to a format required by my database. In my testing I encountered this input date '6-4-3' which should not be valid with the given format. moment('6-4-3','YYYY-MM-DD',true).isValid(); //returns true The resulting date in the moment object is "Mon Apr 03 0006 ...". When I call isValid, it returns true. I think it should consider this date invalid because it has too few digits in the input for each part of the format string. I added a regex.test in my code to ensure

DataGridView Validation & Changing Cell Value

由 为君一笑 提交于 2019-11-30 06:31:12
问题 I would like to manipulate a cell in my DataGridView when it is validating so that if the user enters a value that is not valid for the database, but is easily converted to valid data, the program will change the value to an appropriate one.

Here is my code: private void unit_List_2_GroupsDataGridView_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) { Console.WriteLine

由 南笙酒味 提交于 2019-11-28 05:15:14
I use C#. I have a Windows Form with an edit box and a Cancel button. The edit box has code in validating event. The code is executed every time the edit box loses focus.

How to make HTML input tag only accept numerical values?

由 僤鯓⒐⒋嵵緔 提交于 2019-11-26 11:39:48
I need to make sure that a certain <input> field only takes numbers as value. The input is not part of a form. Hence it doesn't get submitted, so validating during submission is not an option.
