The art of efficiently mass-producing entries

Question

The art of efficiently mass-producing entries

For my application, I need users to answer 50 questions. These questions are retrieved through a web service along with their corresponding answers, all assigned to a unique ticket number.

The challenge is in displaying and saving the user's choices. What would be the best practice in this scenario?

I am using TypeScript and Angular for development.

Currently, I have set up a table with 50 rows, each containing a dropdown list for answering a question. The questions are pre-fetched and displayed in the dropdowns.

However, I am struggling with accessing and identifying which questions the users have answered and saved within these 50 records.

My goal is to save all responses at once if all are answered, or individually if needed (although it might not be an ideal solution due to transaction autonomy concerns).

I attempted to use formGroup for the table but encountered issues.

Perhaps my approach with the table structure is incorrect?

Any assistance on this matter would be greatly appreciated!

When considering user experience and project requirements, there are important factors to keep in mind.

For users answering multiple questions, constantly clicking on dropdowns and waiting for answers can be frustrating. To improve this, it's recommended to fetch all questions and related answers in a single http call from the web service and display them in a table or another suitable element.

On the other hand, if users only require a few answers, your current approach is effective. Using Angular with Reactive Forms and FormArray makes it simple to implement. A sample implementation could look like this:

<div *ngFor="let question of questions">
  <button (click)="questionsUnfoldedMap[question.id]">Fold/Unfold</button>
  <p>{{ question.title }}</p>
  <app-related-questions *ngIf="isQuestionUnfolded()" 
                         [relatedAnswers]="relatedAnswersMap[question.id]"
                         (questionAnswered)="onQuestionAnswered(question.id, $event)">
  </app-related-questions>
</div>

In this code snippet, you maintain a map to track folded/unfolded questions and another map to store related answers. When a user answers a question, the data is stored in a form array to be submitted to the server later.

Consider sending all data in a single http call to the web service to streamline the process, especially if all questions will be answered. This avoids making numerous calls to the server for each question.

Thank you for your response. I believe displaying all 50 questions at once is the most optimal solution, with each question having approximately 2-5 answers in a dropdown list.

Here is what I have implemented in HTML:

<div class="row justify-content-center">
    <div class="col-8">
        <form name="editForm" novalidate (ngSubmit)="submit()" #editForm="ngForm">
            <h2 id="jhi--entry-heading">Create or edit an Entry Test</h2>
            <div class="table-responsive" *ngIf="Questions">
                <table class="table table-striped">
                    <thead>
                        <tr jhiSort [(predicate)]="predicate" [(ascending)]="reverse" [callback]="reset.bind(this)">
                            <th jhiSortBy="id"><span>ID</span>
                                <fa-icon [icon]="'sort'"></fa-icon>
                            </th>
                            <th jhiSortBy="name"><span>Question</span>
                                <fa-icon [icon]="'sort'"></fa-icon>
                            </th>
                        </tr>
                    </thead>
                    <tbody infinite-scroll (scrolled)="loadPage(page + 1)" [infiniteScrollDisabled]="page >= links['last']" [infiniteScrollDistance]="0">
                            <tr *ngFor="let Question of Questions ;trackBy: trackId; let i = index;">
                            <th scope="row">{{Question.id}}</th>
                            <td>{{Question.name}} {{Question.description}}</br>
                                      <select class="form-control" id="answerid">
                                        <option disabled hidden [value]="selectUndefinedOptionValue">-- select --</option>
                                        <option *ngFor="let answer of Question.answers; let j = index;" [value]="answer.id">{{answer.description}}</option>
                                    </select>
                            </td>
                        </tr>
                    </tbody>
                    <div>
                        <button type="button" id="cancel-save" class="btn btn-secondary" (click)="previousState()">
                            <fa-icon [icon]="'ban'"></fa-icon>&nbsp;<span>Cancel</span>
                        </button>
                        <button type="submit" id="save-entity" [disabled]="editForm.form.invalid || isSaving" class="btn btn-primary">
                            <fa-icon [icon]="'save'"></fa-icon>&nbsp;<span>Save</span>
                        </button>
                    </div>
        </form>
    </div>

The table functions properly as it retrieves data from the service and allows selection from the drop-down list. However, I am unsure how to access individual records in the table from TypeScript. My goal is to retrieve the selected answer along with its related question. Is there a way to obtain the entire table as one object?
