mapping

问题 I have a function which triggers children checkboxes once main checkbox is checked, and all these checkboxes are mapped from JSON. The main checkboxes (Highest level) and all of its children checkboxes (2nd level) under them are shown on click and its working great, what I am trying to display is the children of those children of the main checkboxes (3rd level) on clicking the 2nd level items. Basically to show all three orders under each other on check, and add the 3rd order to my current

问题 I am attempting to use Dapper to map to my DTO: public class MyDto { public int Id { get; set; } public string Code { get; set; } public IDictionary<string, object> AdditionalColumns { get; set; } } I can have an instance of MyDto populate the first two properties based on convention, but I'm not sure how to tell Dapper to map all remaining columns into the dictionary. connection.Query<MyDto>("Get_Something", commandType: CommandType.StoredProcedure, param: parameters); The stored procedure

问题 The code below contains an array.map function what is the function of term and i and where was it gotten from, and what does the array.map and the onchange do import React, { Component } from 'react'; class Apps extends Component { componentDidMount() { } iLikeFunctions() { console.log('yay functions'); } render() { var array = ['here','we','go']; var no = 'yes'; const display = 'My Name'; return ( <div> <p>{display}</p> <hr /> <input type="text" onChange={this.iLikeFunctions} /> <table>

问题 Is there any way to specify in a fluent nhibernate mapping file a way to only conditionally pull values into a business entity? My current mapping snippet is: HasMany(m => m.GroupUsers) .Table("GroupUsers") .KeyColumns.Add("UserEntityId") .Inverse() .Cascade.All(); Ideally, I'd like to have this (which compiles but throws a runtime error that gu isn't defined): HasMany(m => m.GroupUsers) .Table("GroupUsers") .KeyColumns.Add("UserEntityId") .Where(gu => gu.DeleteDate == null) .Inverse()

问题 I have a Dozer mapping with a custom converter: <mapping> <class-a>com.xyz.Customer</class-a> <class-b>com.xyz.CustomerDAO</class-b> <field custom-converter="com.xyz.DozerEmptyString2NullConverter"> <a>customerName</a> <b>customerName</b> </field> </mapping> And the converter: public class DozerEmptyString2NullConverter extends DozerConverter<String, String> { public DozerEmptyString2NullConverter() { super(String.class, String.class); } public String convertFrom(String source, String

问题 I want to put/wrap images to 3D objects. To keep things simple and fast, instead of using(and learning) a 3D library I want to use mapping images. Mapping images are used in such a way: So you generate the mapping images once for each object and use the same mapping for all images you want to wrap. My question is how can I generate such mapping images (given the 3D model)? Since I don't know about the terminology my searches failed me. Sorry if I am using the wrong jargon. Below you can see a

问题 Why would the map method mutate the original array when its initial purpose is to create a new array ? I have an array of object which I pass to a pure function which in turn maps the given array and return a new one. Then I notice that the original array was also changed.. I understand the concept that Object in Js are passed by reference and all but still cant quite grab why would the implementation of map would mutate the original array, kinda beats the purpose IMO. var initialArray = [ {
