Vue.js: Using prerendered html as template for parent and child components

hope this fix your issue I'm currently rendering all the html server-side and I'm trying to get vue to use this html as the $el for the following two components. As far as I understand from the lifecycle diagram, this should work. , You are missing inline-template
code :
<mod-sidebar class="sidebar" inline-template>

python flask: custom 404 child template only renders parent template's html file

python flask: custom 404 child template only renders parent template's html file

I hope this helps you . My home.html works just fine. I made my child template, the 404 custom error page inherit the home.html file. However, when I run it, the error page inherits the home.html without rendering the rest of the html on the 404.html. What am I doing wrong? , Think you forgot to add the {% block %} tags in your home.html
code :
<!Doctype html>
<html>
<head>
{% block title %}
<title>Katherine Low's Blog</title>
{% endblock %}
<style>
.menu {
    text-align: center;
    font-size: 1em;
    margin: 10%;
}
.button {
  display: inline-block;
  width: 20%;  
  height: 20%;
}
#current_page {
    text-decoration: underline;
}
a {
    text-decoration: none;
    color: black;
}
a:hover {
    text-decoration: underline;
}
a:active {
    text-decoration: underline;
}
</style>
</head>
<body>
{% block body %}

<div class="menu">
    <div class="button" id="current_page"><a href="http://localhost:5000/blog/" />BLOG</div>
    <div class ="button"><a href="http://localhost:5000/about/">KATHERINE LOW</a></div>
    <div class="button"><a href="http://localhost:5000/projects/">PROJECTS</a></div>
</div>

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script>
  window.jQuery || document.write('<script src="{{
  url_for('static', filename='jquery.js') }}">\x3C/script>')</script>
<script type="text/javascript"> 
  $(document).ready(function(){
    $('.button').hover(
      function(){
        $('#current_page').css("text-decoration", "none");
      }, function() {
        $('#current_page').css("text-decoration", "underline");
      }
    );

  });
{% endblock %}
</script>
</body>
</html>
How to share parent HTML between two child Angular2 components?

it helps some times Angular is a "Single Page Application" framework. For example you if you had a login page your code might look something like this:
code :
<html>
  <body>
    <header-component/>
    <login-component/>
  </body>
</html>
<html>
  <body>
    <header-component/>
    <profile-component/>
  </body>
</html>
Changing a child components state changes the parent components props

To fix this issue Parent component is a header , Javascript object are assigned by reference so when you do
code :
constructor(props) {
    super(props);
    this.state = {
      object: props.object,
      hidden: props.hidden,
    };
}
this.setState((prevState) => {
  const object = { ...prevState.object };
  object[key][subkey] = value;
  return { object };
});
object[key][subkey] = value;
  const object = { ...prevState.object,
                      [key]: {
                          ...prevState[key],
                          [subkey]: { ...prevState[key][subkey]}
                      }
                   };
  object[key][subkey] = value;

wish of those help I ended up using @AngularInDepth's approach. The first one didn't work for me since I couldn't find context, but the second one did. I was trying to do the same thing, but instead of adding the 'instance' of the component in an array, I was pushing the entire (this.container.createComponent(comp)) in an array which was causing problems for me.

around this issue I have to objects named Service with a child Requirements. What im trying to achieve is, First Filtering the service object and and displaying it and below of it display count of requirements. something like in below image. which shows the Service and count of Requirement associated to the Services, and also displaying Total count of requirements with status = 'Verified' , So based on your models and what you want to achieve:
template
code :
<table>
  {% for service in services %}
    <tr>
      <td>{{ service.services }}
        <ul>
          <li>Total Requirements Count = {{ service.requirements_set.count }}</li>
          <li>Total Verified Count = {{ service.get_verifed_req_count }}</li>
        </ul>
      </td>
    </tr>
  {% endfor %}
</table>
class Service(models.Model):
    service = models.CharField(null=False, max_length=254)
    company = models.ForeignKey(Company_Data, on_delete=models.CASCADE)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    def get_verifed_req_count(self):
        return self.requirements_set.filter(reqdoc_status='Verified').count()


class Requirements(models.Model):
    Requirements = models.CharField(null=False, max_length=254)
    file = models.CharField(null=False, max_length=254)
    services = models.ForeignKey(Service, on_delete=models.CASCADE)
    status = models.CharField(null=False, max_length=254)
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)
def test_one(request):
    comp_id = request.session['comp_id']
    service = service.objects.filter(company_id=comp_id)
    context = {'services': service}
    return render(request, 'test1.html', context)
