Typescript type RequireSome<T, K extends keyof T> removing undefined AND null from properties

由 為{幸葍}努か 提交于 2021-02-20 02:59:29
问题 RequireSome type from another, very simialar question. This question is similar but it should not be a duplicate since here we want to also remove null as well as undefined from properties. Maybe the name shouldn't be Require but something like NonNullable or of this kind. The goal of this type is to specify which fields from a type should not be undefined or null, and return their types without undefined and null. type Question = { id: string; answer?: string | null; thirdProp?: number |

Required field in Django model not mandatory?

由 大城市里の小女人 提交于 2020-08-07 06:17:39
问题 I have the following Django model: class Customer(models.Model): email = models.EmailField(unique=True) In my testcase, I instantiate it without an e-mail. class CustomerTestCase(TestCase): def test_that_customer_can_be_created_with_minimum_data(self): customer = Customer.objects.create() print(customer.__dict__) I expect it to raise an error, but it creates a record with an empty field email . The same thing happens if I explicitly say null=False and blank=False . Instead, it just prints the

Form inputs in modal not showing as required

由 风流意气都作罢 提交于 2020-05-14 02:32:54
问题 I've read through some related articles without any luck of solving my own issue of getting form fields to appear as required. Perhaps the problem lies outside but I wanted to share in case it highlights a unique case. This is a class assignment viewable in entirety here, it allows the user to add new trains to a schedule and update a Firebase DB. For this I used Bootstrap for the styles and also a modal pop-up that contains the form to create the new train. Everything works well, except that

How do I make radio buttons, select boxes, and checkboxes required fields in a form?

由 笑着哭i 提交于 2019-12-13 05:59:35
问题 I've set up my code so that it would require all the fields within the form, but for some reason it's only applying to input types of text, email, and password. So my question is how can I get the radio buttons, select boxes, and checkbox to also be required fields within the form? Here's my code: <form action="" method="post"> <ul id="register"> <li> <input type="text" name="first_name" placeholder="First Name"> </li> <li> <input type="text" name="last_name" placeholder="Last Name"> </li>

How to validate values instantly, but check for required only on full submit?

由 大城市里の小女人 提交于 2019-12-04 16:44:39
I am currently adding validation to a form. There are two things to check: The correctness of the value itself (e.g. if it is a positive integer or valid email) and whether all required fields were filled in. However, if by some means ( f:ajax or IceFaces partialSubmit attribute) I make the validation for type correctness happen at once (e.g. when the field loses focus), it will also check the required attribute in this same step. In most cases this is no problem, as the user already entered a value and is likely to correct it rather than go back to a blank field. However, in the case where he

Is it possible to configure a required field to ignore white space?

由 。_饼干妹妹 提交于 2019-11-30 06:17:38
问题 The required attribute in HTML5 is very handy: <input type="text" required> But it still allows users to enter white space only. Is there an HTML-only solution to this? 回答1: Use the pattern attribute combined with the required attribute. And be sure to include a title attribute as well, since most browsers insert the title text into the validation pop-up bubble. <input required pattern=".*\S+.*" title="This field is required"> The .*\S+.* pattern requires at least one non-whitespace character
