    <p>i am trying to use set function in appengine, to prepare a list with unique elements. I hit a snag when i wrote a python code which works fine in the python shell but not in appengine + django</p> <p>This is what i intend to do(ran this script in IDLE):</p> <pre><code>import re value=' r.dushaynth@gmail.com, dash@ben,, , abc@ac.com.edu ' value = value.lower() value = list(set(re.split('^\s*|\s*,+\s*|\s*$', value))) if (value[0] == ''): value.remove('') print value </code></pre> <p>The desired output is(got this output in IDLE):</p> <pre><code>['dash@ben', 'abc@ac.com.edu', 'r.dushaynth@gmail.com'] </code></pre> <p>Now when i do something equivalent in my views.py file in appengine :</p> <pre><code>import os import re import django from django.http import HttpResponse from django.shortcuts import render_to_response # host of other imports also there def add(request): value=' r.dushaynth@gmail.com, dash@ben,, , abc@ac.com.edu ' value = value.lower() value = list(set(re.split('^\s*|\s*,+\s*|\s*$', value))) if (value[0] == ''): value.remove('') return render_to_response('sc-actonform.html', { 'value': value, }) </code></pre> <p>I get this error while going to the appropriate page(pasting the traceback):</p> <pre><code>Traceback (most recent call last): File "G:\Dhushyanth\Google\google_appengine\lib\django\django\core\handlers\base.py" in get_response 77. response = callback(request, *callback_args, **callback_kwargs) File "G:\Dhushyanth\development\AppengineProjects\trunk_sanjhachoolha\sandbox\dushyanth\sanjhachoolha\views.py" in add 148. value = list(set(re.split('^\s*|\s*,+\s*|\s*$', value))) File "G:\Dhushyanth\development\AppengineProjects\trunk_sanjhachoolha\sandbox\dushyanth\sanjhachoolha\views.py" in list 208. return respond(request, None, 'sc-base', {'content': responseText}) File "G:\Dhushyanth\development\AppengineProjects\trunk_sanjhachoolha\sandbox\dushyanth\sanjhachoolha\views.py" in respond 115. params['sign_in'] = users.create_login_url(request.path) AttributeError at /sanjhachoolha/acton/add 'set' object has no attribute 'path' </code></pre> <p>on commenting out:</p> <pre><code>#value = list(set(re.split('^\s*|\s*,+\s*|\s*$', value))) </code></pre> <p>I get the desired output in the appropriate webpage:</p> <pre><code>r.dushaynth@gmail.com, dash@ben,, , abc@ac.com.edu </code></pre> <p>I am sure the list() is the root of my troubles. CAn anyone suggest why this is happening. Please also suggest alternatives. The aim is to remove duplicates from the list.</p> <p>Thanks</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
