    <p>So I have some code:</p> <pre><code>signature = hmac.new( key=AWS_SECRET_ACCESS_KEY, msg=string_to_sign, digestmod=hashlib.sha256).digest() </code></pre> <p>That runs perfectly on my own computer (has python 2.6.1). However, when I run this code on my server (Python 2.4.3) I get the following:</p> <pre><code> /home/MYUSERNAME/public_html/Foo.com/cgi-bin/foo.py 66 key=AWS_SECRET_ACCESS_KEY, 67 msg=string_to_sign, 68 digestmod=hashlib.sha1).digest() 69 70 # Base64 encode the signature digestmod = &lt;built-in function openssl_sha256&gt;, hashlib = &lt;module 'hashlib' from '/usr/lib/python2.4/site-...shlib-20081119-py2.4-linux-i686.egg/hashlib.pyc'&gt;, hashlib.sha1 = &lt;built-in function openssl_sha1&gt;, ).digest undefined /usr/lib/python2.4/hmac.py in new(key='xR6MsC/+Vc2xkd0YYbER0meR/IkWEU', msg='GET\necs.amazonaws.com\n/onca/xml\nAWSAccessKeyId=A...CommerceService&amp;Timestamp=2010-07-03T18%3A56%3A48', digestmod=&lt;built-in function openssl_sha1&gt;) 103 You can now feed arbitrary strings into the object using its update() 104 method, and can ask for the hash value at any time by calling its digest() 105 method. 106 """ 107 return HMAC(key, msg, digestmod) global HMAC = &lt;class hmac.HMAC&gt;, key = 'xR6MsC/+Vc2xkd0YYbER0meR/IkWEU', msg = 'GET\necs.amazonaws.com\n/onca/xml\nAWSAccessKeyId=A...CommerceService&amp;Timestamp=2010-07-03T18%3A56%3A48', digestmod = &lt;built-in function openssl_sha1&gt; /usr/lib/python2.4/hmac.py in __init__(self=&lt;hmac.HMAC instance&gt;, key='xR6MsC/+Vc2xkd0YYbER0meR/IkWEU', msg='GET\necs.amazonaws.com\n/onca/xml\nAWSAccessKeyId=A...CommerceService&amp;Timestamp=2010-07-03T18%3A56%3A48', digestmod=&lt;built-in function openssl_sha1&gt;) 40 41 self.digestmod = digestmod 42 self.outer = digestmod.new() 43 self.inner = digestmod.new() 44 self.digest_size = digestmod.digest_size self = &lt;hmac.HMAC instance&gt;, self.outer undefined, digestmod = &lt;built-in function openssl_sha1&gt;, digestmod.new undefined AttributeError: 'builtin_function_or_method' object has no attribute 'new' args = ("'builtin_function_or_method' object has no attribute 'new'",) </code></pre> <p>I know the obvious response is to just update Python on my server, but my host has to do that and I don;t know how long it'll take. I'm just curious if this is a common/known issue on 2.4.3 or if something else is going on.</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.
