Issues with view function and form inclusion

Using Django Mystery Errors
1

Hello!

I have two app in my project where I want to render the the query from a certain view from app 1 to another template inside app 2. I hope it makes sense.

I’ve done some research and one way is to render the query from app 1 in a template in app 1 and then include it, using {% include “template path” %}, inside a template in app 2 where it is supposed to be displayed.

My question is, is this really the correct way?

I tried this technique for a random text and it was displayed in my template in app 2. However, the actual view function is not rendered.

Is there something wrong in the logic?

I have made sure that there are instances of User, Room and Comment in the database so the bug must raise from the view function, I believe.

View:

def room_comments(request, room_id):
    room = get_object_or_404(Room, id=room_id)
    comments = Comment.objects.filter(room=room).order_by("-date")

    if request.method == "POST":
        form = CommentForm(request.POST)
        if form.is_valid():
            comment = form.save(commit=False)
            comment.room = room
            comment.member = request.user
            comment.save()

            return HttpResponseRedirect(reverse("main_app:roomdetail", args=[room_id]))
    else:
        form = CommentForm()

    context = {"comments": comments, "form": form, "room": room}
    return render(request, "main_app/roomspage_roomdetail.html", context)

URL

from django.urls import path, include
from . import views

app_name = "messages_app"

urlpatterns = [
    path("<int:room_id>/", views.room_comments, name="room_comments"),

]

Model:

class Comment(models.Model):
    room = models.ForeignKey(
        Room, on_delete=models.CASCADE)
    member = models.ForeignKey(
        Member, on_delete=models.CASCADE, null=True)

    body = models.TextField(max_length=150, blank=False)
    comment_date = models.DateTimeField(auto_created=True)

    def __str__(self):
        return str(self.body[0:20])

Template in app 1:

{% block content %}

    {% for comment in comments %}
        {{comment.body}}
    {% endfor %}

    <form action="#" method = "POST">
        {% csrf_token %}
        {{form}}
    </form>
{% endblock content %}

I appreciate all tips!

You want to change your perspective and how you’re thinking about this.

The user submits a request for a URL.

That request is mapped to a view.

That view can execute queries, perform other functions, and render templates.

When that view is finished, it then returns an HttpResponse.

Where that code and those templates reside is pretty immaterial. Any view may render any template.

The views do the work. Views are not rendered. Views do the rendering. The templates are just data used by the view to help create (usually) an HTML page.

Hello!

Excuse my missuse of terminology. I’ve read through the documentation for URLs and views and I’ll try to be more concise in my use of Django terminologi in the future.

I appreciate if you guide me on how I can display the resulting query rendered by a view in app 1 (messages app) in another template in app 2 (main app).

The two apps have different URLs in the root directory:

urlpatterns = [
    path("admin/", admin.site.urls),
    path("home/", include("main_app.urls")),
    path("messages/", include("messages_app.urls")),
]

Whenever I make a request to the URL in app 1, the request is mapped to a view function in app 1 and the executed query are displayed in a template using messages/(instance id), in the URL. But I want to render all the messages that the view function render in a template located in app 2.
