    <p>If I have an object like:</p> <pre><code>d = {'a':1, 'en': 'hello'} </code></pre> <p>...then I can pass it to <code>urllib.urlencode</code>, no problem:</p> <pre><code>percent_escaped = urlencode(d) print percent_escaped </code></pre> <p>But if I try to pass an object with a value of type <code>unicode</code>, game over:</p> <pre><code>d2 = {'a':1, 'en': 'hello', 'pt': u'olá'} percent_escaped = urlencode(d2) print percent_escaped # This fails with a UnicodeEncodingError </code></pre> <p>So my question is about a reliable way to prepare an object to be passed to <code>urlencode</code>.</p> <p>I came up with this function where I simply iterate through the object and encode values of type string or unicode:</p> <pre><code>def encode_object(object): for k,v in object.items(): if type(v) in (str, unicode): object[k] = v.encode('utf-8') return object </code></pre> <p>This seems to work:</p> <pre><code>d2 = {'a':1, 'en': 'hello', 'pt': u'olá'} percent_escaped = urlencode(encode_object(d2)) print percent_escaped </code></pre> <p>And that outputs <code>a=1&amp;en=hello&amp;pt=%C3%B3la</code>, ready for passing to a POST call or whatever.</p> <p>But my <code>encode_object</code> function just looks really shaky to me. For one thing, it doesn't handle nested objects.</p> <p>For another, I'm nervous about that if statement. Are there any other types that I should be taking into account? </p> <p>And is comparing the <code>type()</code> of something to the native object like this good practice? </p> <pre><code>type(v) in (str, unicode) # not so sure about this... </code></pre> <p>Thanks!</p>

    1. COit should be `u'olá'` instead of `u'óla'`...

    3. COjust a thought on your last sentence: it should be `if isinstance(v, unicode)` rather than `if type(v) in ...`, also no need to match str as it does not need encoding

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.
