identity

问题 I'm trying to add a column to the identity (asp net core) RoleClaims table but I find content just to extend the roles and users classes and not to RoleClaims. Could someone help with examples or point out content. 回答1: You would need to create a new class to extend the RoleClaim . Here is an example of how to do it if your key type is string : public class ApplicationRoleClaim : IdentityRoleClaim<string> { public virtual ApplicationRole Role { get; set; } } You can add whatever new

问题 Why does the following happen with Python's lambdas (in both Python 2 and 3)? >>> zero = lambda n: n is 0 >>> zero(0) True >>> zero = lambda n: n is 0.0 >>> zero(0.0) False 回答1: The most common Python implementation store a number of small integers as "constant" or "permanent" objects in a pre-allocated array: see the documentation. So, these numbers can be recongized as identical objects using the is operator. This is not done for floats. If you were to compare the numbers using the equality

问题 Why do ranges which are initialized with different values compare equal to one another in Python 3? When I execute the following commands in my interpreter: >>> r1 = range(0) >>> r2 = range(2, 2, 2) >>> r1 == r2 True The result is True . Why is this so? Why are two different range objects with different parameter values treated as equal? 回答1: The range objects are special: Python will compare range objects as Sequences . What that essentially means is that the comparison doesn't evaluate how
