• Incorrect parsing response from feign client

  I have a simple Feign client:

  @FeignClient(
  serviceId = "${com.service}",
  fallbackFactory = AccountFeignServiceClient.AccountFallBackFactory.class)
  public interface AccountFeignServiceClient {
  
    @GetMapping("/users/{id}")
    ResponseEntity<AccountDto> getUser(@PathVariable("id") String id);
  }
  

  Method in another server:

  @GetMapping(value = "/users/{id}")
  ResponseEntity<?> getUser(@PathVariable(value = "id") String id) {
    return ok(...);
  }
  

  Problem is that AccountDto have only null fields. After debag I found the following reason for this behavior. If i get the response in in feign client of type string it will be like:

  {"headers":{},"body":{"id":"d267294f-d4b2-493b-9829-63ece48922e9"},"statusCode":"OK","statusCodeValue":200}
  

  But if i get the response of type ResponseEntity<?> i will get this:

  You can see it have double body and i have no ideas why. With type ResponseEntity<?> i expect response like:

  
• Find an object in Hibernate without id

  I'm using Spring. I have a user table.

  When a person logins to the system, he sends me his credentials (i.e. username and password).

  I stored my users in database with "incremental generated uid" (i.e. userid is primary key).

  I also stored the username password etc. in the database. What I need to do is, when the user connects to the Rest connection, I need to check whether the database has this user or not. If he exists, then I need to check if passwords are matching. And I need to do that checking by username, rather than uid

  I dont have session or anything at all in my program (Or as far as I know, I didn't write any session or sessionfactory in my code at all)

  My repository class:

  public interface UserRepository extends JpaRepository<User, Long>{
  }
  

  My user DAO

  @Service
  public class UserDAO {
  
      @Autowired
      UserRepository userRepository;
  
      public User findByUsername(String username)
      {
          //what to write here
  
      }
  }
  

  I've looked up this solution but as I stated above, I don't have session.

• How can i add the data in a object and in other object insert the info in an array?

  I would like to know if this is correctly done, I want to insert the data of the attributes of the material object in a list. In the function of the material object, I give value to the material attributes and then add this data in a list that will do so in the library function.

  I want to give value to an object and add its values ​and be able to show the result of the list

  Also when I print the list the message that comes out is this [<__ main __. Material object at 0x03994ED0>]

• Calculator.java Review And Opinions

  Here's A Java Calculator Program I Just Made Recently, But It Doesn't Meet My Expectations! I Want It In A More Convenient Way Like It Has 6 Classes And Some Exclamation Marks, I Wanna Get A+ So Please Help Me!

  1) Can I loop the codes so after displaying the answer, It runs the code again? 2) Can I somehow decrease the number of classes and the length of codes? 3) Can I clear screen in the console like in C++, So it should display a separate view for the Intro and the answer?

  Here's The Code:

• Mongoose Populate with Express, not working in production (Heroku)

  This is a MERN app, hosted on github, and it works perfectly on localhost. Unfortunately, it does not work on Heroku.

  The issue is the API request, it must return an object and populate an array of OIDs (see Department Model). API request is working. I'm getting the data from MLab, but it doesn't populate... instead returns: "surveys":[]

  API File

  router.get('/department_data/:d_oid', function(req, res) {
       Department.findOne({_id: req.params.d_oid}).populate("surveys").exec(function(err,doc){
            if(err) throw(err)
            res.send(doc)
       })
  });
  

  Department Model

  **Department Model**
  var mongoose = require("mongoose");
  var Schema = mongoose.Schema;
  
  // Create the survey schema
  var departmentSchema = new Schema({
  
    department_name: {

      trim: true,
      required: true
    },

  departmentSchema.index({ department_name: 1, created_by: 1}, {unique: true});

• Selecting City based on Country in React

  In my project Country is hard coded and I want to select States based on selected country.

  stateList is an arraycollection to store all the states.

  Now by this code I'm displaying all the states.

  But I actually need the states based on the selected country.

  What should be the function to do it using the given piece of code?

  PS : stateList is populating from db
• Django Admin - Prepopulate field and set readonly

  i want to set a field (current user) in a model automatically when an object gets created or is being updated and make it readonly, so the user can not change it:

  In order to prepopulate the field:

  @admin.register(Model)
  class ModelAdmin(admin.ModelAdmin):
      list_display = ('field_1', 'user')
  
      def get_form(self, request, obj=None, **kwargs):
          form = super(ModelAdmin, self).get_form(request, obj, **kwargs)
          form.base_fields['user'].initial = request.user
          return form
  

  This works, but when i then want to make the field readonly using:

  readonly_fields=('user', )
  

  the app crashed with error:

  KeyError at /admin/api/model/add/
  'user'
  

  Can anybody help me out and explain how i can reach my goal using django admin?

  thanks!
