    <p>Here is a quick Python script which downloads a Youtube video. No bells and whistles, just scrapes out the necessary urls, hits the generate_204 url and then streams the data to a file:</p> <pre><code>import lxml.html import re import sys import urllib import urllib2 _RE_G204 = re.compile('"(http:.+.youtube.com.*\/generate_204[^"]+")', re.M) _RE_URLS = re.compile('"fmt_url_map": "(\d*[^"]+)",.*', re.M) def _fetch_url(url, ref=None, path=None): opener = urllib2.build_opener() headers = {} if ref: headers['Referer'] = ref request = urllib2.Request(url, headers=headers) handle = urllib2.urlopen(request) if not path: return handle.read() sys.stdout.write('saving: ') # write result to file with open(path, 'wb') as out: while True: part = handle.read(65536) if not part: break out.write(part) sys.stdout.write('.') sys.stdout.flush() sys.stdout.write('\nFinished.\n') def _extract(html): tree = lxml.html.fromstring(html) res = {'204': _RE_G204.findall(html)[0].replace('\\', '')} for script in tree.findall('.//script'): text = script.text_content() if 'fmt_url_map' not in text: continue # found it, extract the urls we need for tmp in _RE_URLS.findall(text)[0].split(','): url_id, url = tmp.split('|') res[url_id] = url.replace('\\', '') break return res def main(): target = sys.argv[1] dest = sys.argv[2] html = _fetch_url(target) res = dict(_extract(html)) # hit the 'generate_204' url first and remove it _fetch_url(res['204'], ref=target) del res['204'] # download the video. now i grab the first 'download' url and use it. first = res.values()[0] _fetch_url(first, ref=target, path=dest) if __name__ == '__main__': main() </code></pre> <p>Running it:</p> <pre><code>python youdown.py 'http://www.youtube.com/watch?v=Je_iqbgGXFw' stevegadd.flv saving: ........................... finished. </code></pre>

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.
