Cannot Render Entries to Page

I'm making a simple blog for myself in Django, but having a strange issue. I have a simple model as shown below:

Entry:
    - title
    - content

This is the template I'm currently using:

{% for entry in context.entries %}
<div class="row">
    <div class="col-xl-2 col-lg-2 col-md-2 hidden-sm hidden-xs"></div>
    <div class="col-xl-8 col-lg-8 col-md-8 col-sm-12 col-xs-12">
    <div class="entry">
        <div class="header">
            <table>
                <tr>
                    <td class="title"><h2>{{ entry|title }}</h2></td>
                    <td class="datetime">01.01.2016 00:00:00</td>
                </tr>
            </table>
        </div>
        <div class="content">
            {{ entry|content }}
        </div>
        <div class="footer">
            <a href="#">#some</a>
            <a href="#">#tag</a>
            <a href="#">#right</a>
            <a href="#">#here</a>
        </div>
    </div>
    <div class="col-xl-2 col-lg-2 col-md-2 hidden-sm hidden-xs"></div>
    </div>
    </div>
{% endfor %}

However, I'm getting TemplateSyntaxError on the {{ entry|content }} line, which is strange.

views.py file:

import json, termcolor
from django.shortcuts import render
from django.http import HttpResponse
from .models import *

# Create your views here.
def index(request, page="1"):
    page = int(page)
    context = {
        "title": "Erdin's Blog",
        "entries": []
    }

    entries = Entry.objects.all()
    r_entries = entries[::-1]
    del entries
    interest = [page*10-10, page*10]

    context["entries"].extend(r_entries[interest[0]:interest[1]])

    print(termcolor.colored(context["entries"][0].content, "green"))

    return render(request, "home.elms.html", context)

Further Investigation

I already have a single entry on database. I also checked if it's queried correctly into database with sqliteman. Assuming I named this single entry as entry variable, I called entry.id, entry.title and entry.content and printed out to terminal, that was successful. There's no problem on database.

Environment

A Complete Edit

I currently realized the problem was completely different. I called {% for entry in context.entries %} but I already called context into template, so the engine was looking for a context key inside context dictionary.

Since I solved my own problem, I'm writing here for the sake of other users having same problem.

Since I returned a render in views.py as below:

render(request, "home.elms.html", context)

The template should call for dictionary inside the context as:

{% for entry in entries %}

not:

{% for entry in context.entries %}

The | syntax is for template filters. To get the model values in the template there is a dot notation:

{{ entry.title }}
{{ entry.content }}

Note that the reason why {{ entry|title }} did not throw any errors is that there is a built-in title template filter. But there is no content template filter - this is why you see the error on the line containing {{ entry|content }}.
