title: Accessing json object array and showing in Angular 4
body: <p>I have object that consists of fields, other objects and arrays and it looks like this</p>
  
  <p>Now, in my html, I access data for aaType, adjust etc.</p>
  
  <pre><code>&lt;div class="flexdirectioncolumn"&gt;
      &lt;div class="flex50"&gt;
          &lt;label class="label-prop-a"&gt; Name &lt;/label&gt;
          &lt;div&gt;
              &lt;input #name type="text" value={{entity.name}} (keyup.enter)="changeName(name.value)" /&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="flex50"&gt;
          &lt;label&gt; AaType &lt;/label&gt;
          &lt;div&gt;
              &lt;input #aaType type="text" value={{entity.aaType}} (keyup.enter)="changeAaType(aaType.value)" /&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="flex50"&gt;
          &lt;label&gt; Adjust &lt;/label&gt;
          &lt;div&gt;
              &lt;input #adjustableInput type="checkbox" value={{entity?.adjust}} (keyup.enter)="changeAdjust(adjustInput.value)" /&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="flex50"&gt;
          &lt;label&gt; System &lt;/label&gt;
          &lt;div&gt;
              &lt;input #systemInput type="text" value={{entity?.system}} /&gt;
          &lt;/div&gt;
      &lt;/div&gt;
      &lt;div class="flex50"&gt;
          &lt;label&gt;{{entity.creat.rule}}&lt;/label&gt;
          &lt;div *ngFor="let param of entity.creat.parameters"&gt;
              &lt;label&gt;{{param}}&lt;/label&gt;
              &lt;input type="text" value={{param.value}} /&gt;
          &lt;/div&gt;
      &lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I managed to show creationInfo.rule that you can see in my html.</p>
  
  <p>Now there is 2 questions that is bothering me:</p>
  
  <ol>
  <li>For some reason, I can't access parameters array so I can use ngFor to create them all.</li>
  <li>How can I show my label and input in ngFor div in a way that label will generate parameters name (like "departure-angle") and value in input to show "13"?</li>
  </ol>
