    <p>I'm trying to use the map of nginx, but the results aren't what I expect.</p> <p>This is what I have:</p> <pre><code>map $uri $new { default ""; ~*/cc/(?P&lt;suffix&gt;.*)$ test.php?suffix=$suffix; } location ~ [a-zA-Z0-9/_]+$ { proxy_pass http://www.domain.com:81/$new; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } </code></pre> <p>When I go to www.domain.com/cc/abc, I see this in the logs</p> <pre><code>2012/03/29 17:27:53 [warn] 3382#0: *33 an upstream response is buffered to a temporary file /var/cache/nginx/proxy_temp/5/00/0000000005 while reading upstream, client: 1.2.3.4, server: www.domain.com, request: "GET /cc/abc HTTP/1.1", upstream: "http://1270.0.0.1:81/test.php?suffix=$suffix", host: "www.domain.com" </code></pre> <p>The $suffix isn't replaced.</p> <p>But when I do this:</p> <pre><code>map $uri $new { default ""; ~*/cc/(?P&lt;suffix&gt;.*)$ $suffix; } location ~ [a-zA-Z0-9/_]+$ { proxy_pass http://www.domain.com:81/$new; proxy_set_header X-Real-IP $remote_addr; proxy_set_header Host $host; proxy_set_header X-Host $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } </code></pre> <p>And now, when I go to go to www.domain.com/cc/abc, the logs show me this:</p> <pre><code>2012/03/29 17:29:39 [warn] 5916#0: *26 an upstream response is buffered to a temporary file /var/cache/nginx/proxy_temp/2/00/0000000002 while reading upstream, client: 1.2.3.4, server: www.domain.com, request: "GET /cc/abc HTTP/1.1", upstream: "http://1270.0.01:81/abc", host: "www.domain.com" </code></pre> <p>So, when the rewrite contains a string including the variable, it isn't replaced. But if it only contains the variable, it will work.</p> <p>What am I doing wrong?</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.
