Reading from a file and displaying into a table on the web app.

[Ravi Hemnani]

Hey,

I am trying to build an interface using django. This way i am learning django as well.

So i have completed web-poll tutorial and i tried something on my own.

My problem, 

I have a file with following content.

# Stats

total_connections_received:2

total_commands_processed:1

instantaneous_ops_per_sec:0

rejected_connections:0

expired_keys:0

evicted_keys:0

keyspace_hits:0

keyspace_misses:0

pubsub_channels:0

pubsub_patterns:0

latest_fork_usec:0

# Keyspace

db0:keys=6,expires=0

Now, i want to display the above content in a table from on the web interface.

Following is my directory structre where mysite is the root app and polls is the secondary app.

7 directories, 29 files

following is my polls/templates/polls/table.html

{% if line %}

    <table style="width:300px">

    {% for x in line  %}

        <tr>

            <td>{{ x }}</td>

        </tr>

    {% endfor %}

    </table>

{% else %}

    <p>No polls are available.</p>

{% endif %}

following is my polls/views.py

from django.shortcuts import get_object_or_404, render

from django.http import Http404, HttpResponse, HttpResponseRedirect

from polls.models import Choice, Poll

from django.core.urlresolvers import reverse

from django.template import RequestContext, loader

from django.views import generic

from django.core.files import File

def table(request):

        with open('/home/ravi/python/temp.txt', 'r') as f:

                for line in f:

                        context = {'line': line}

                return render(request, 'polls/table.html', context)

when it the url, 

http://127.0.0.1:8000/polls/table

I get the following output,

d

b

0

:

k

e

y

s

=

6

,

e

x

p

i

r

e

s

=

0

but i want the output as each line of the file as a row in the table. 

Any help.

Here you are ovwewriting 'content' on every iteration. When the loop exits, only the last line in the file will be in context. You want something like this instead:

def table(request):
with open('/home/ravi/python/temp.txt', 'r') as f:

context = {'lines': f.readlines()}

Hey, 

Sorry to reply so late. I figured that thing out and i was able to send the results into a table successfully. 

Thanks for the help :D
