    <h2>Note</h2> <p>The below answer is <em>not</em> applicable to requests v0.13.0+. The asynchronous functionality was moved to <a href="https://github.com/kennethreitz/grequests" rel="noreferrer">grequests</a> after this question was written. However, you could just replace <code>requests</code> with <code>grequests</code> below and it should work.</p> <p>I've left this answer as is to reflect the original question which was about using requests &lt; v0.13.0.</p> <hr> <p>To do multiple tasks with <code>async.map</code> <em>asynchronously</em> you have to:</p> <ol> <li>Define a function for what you want to do with each object (your task)</li> <li>Add that function as an event hook in your request</li> <li>Call <code>async.map</code> on a list of all the requests / actions</li> </ol> <p>Example:</p> <pre><code>from requests import async # If using requests &gt; v0.13.0, use # from grequests import async urls = [ 'http://python-requests.org', 'http://httpbin.org', 'http://python-guide.org', 'http://kennethreitz.com' ] # A simple task to do to each response object def do_something(response): print response.url # A list to hold our things to do via async async_list = [] for u in urls: # The "hooks = {..." part is where you define what you want to do # # Note the lack of parentheses following do_something, this is # because the response will be used as the first argument automatically action_item = async.get(u, hooks = {'response' : do_something}) # Add the task to our list of things to do via async async_list.append(action_item) # Do our list of things to do via async async.map(async_list) </code></pre>

    1. CONice idea to have left your comment : due to compatibility issues between latest requests and grequests (lack of max_retries option in requests 1.1.0) i had to downgrade requests to retrieve async and I have found that the asynchronous functionality was moved with versions 0.13+ (https://pypi.python.org/pypi/requests)

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.
