问题 I am having troubles with pushing selected checkboxes into the table. I have three tables - Employees , Projects and EmployeeProject . For one Employee I want to be able to choose multiple projects. I already created a create view with inputs for name of the employee and checkboxes of the projects. How can I send data to the EmployeeProjects table? So I could display it later. My models: public class Employee { [Key] public int Id { get; set; } public string FirstName { get; set; } public

问题 I have built up a project and deployed it in iis server and the web.config file looks like, <?xml version="1.0" encoding="UTF-8"?> <configuration> <system.webServer> <rewrite> <rules> <rule name="about" stopProcessing="true"> <match url="^about$" /> <action type="Rewrite" url="/about.html" /> </rule> <rule name="contact" stopProcessing="true"> <match url="^contact$" /> <action type="Rewrite" url="/contact.html" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Folder

问题 i want to have default value in my form which should be current user's choice. For example, user chooses to give 5 for a movie and he should see 5 in form until he changes it. views.py class MovieDetailView(FormMixin, DetailView): model = Movie template_name = 'main/detail_movie.html' context_object_name = 'movie' form_class = RateForm def get_context_data(self, **kwargs): context = super(MovieDetailView, self).get_context_data(**kwargs) context['form'] = RateForm(initial={'movie': self

问题 Why vector[n] = val doesn't give segmentation fault or changes the vector data, right before reserving an empty vector. Check this example: #include <iostream> #include <vector> int main() { std::vector<int> temp; temp.reserve(8); temp[0] = 1; temp[3] = 3; //why no attribution??? temp[7] = 1; temp[8] = 3; //why no segmentation fault??? std::cout << temp.size(); for(auto&a: temp){ //because the attribution didn't work, no loop needed std::cout << a; } return 0; } Also, why the operator []

问题 I am trying to export my stored procedure to a .csv file using BCP. It does give me a output file in .CSV but it does not print column name. Below is the script.

问题 So, I was attempting to use the following example: https://github.com/agiratech/angular4-reactive-form-exercise2/ However, when I implement it, and submit my form, no errors show anywhere on the screen. Below you will find all associated code that I can think of that relates. I'm looking for how to get the errors to show on the screen. I'm fairly new to Angular 4, so any help would be appreciated. pages.module.ts import ... import { FormsModule, ReactiveFormsModule } from '@angular/forms';
