    <p>I am trying to make a query which I haven't been able to yet. My permanent view function is following:</p> <pre><code>function(doc) { if('llweb_result' in doc){ for(i in doc.llweb_result){ emit(doc.llweb_result[i].llweb_result, doc); } } } </code></pre> <p>Depending on the key, I filter the result. So, I need this key. Secondly, as you see, there is a for loop. This causes identical tuples in the result. However, I also need to do this for loop to check everything. In here, I just want to know how to eliminate identical tuples?</p> <p>I am using couchdb-python. My related code is:</p> <pre><code>result = {} result['0'] = self.dns_db.view('llweb/llweb_filter', None, key=0, limit = amount, startkey_docid = '000000052130') result['1'] = self.dns_db.view('llweb/llweb_filter', None, key=1, limit=amount) result['2'] = self.dns_db.view('llweb/llweb_filter', None, key=2, limit=amount) </code></pre> <p>As it is understood from key values, there are three different types of keys. I thought that I can extend the 'key' with [doc._id, llweb_result]. I need a key like [*, 2], but I don't know it is possible. Then, use reduce function to group them. This will definitely work, but at this time the problem is how to make a selection query by using only the values [0,1,2]. </p> <p>Edited in 16.08.12</p> <p>Example for 'llweb_result' property of a couchdb record:</p> <pre><code>"llweb_result": { "1": { "ip": "66.233.123.15", "domain": "domain.com", "llweb_result": 1 }, "0": { "ip": "66.235.132.118", "domain": "domain.com', "llweb_result": 1 } } </code></pre> <p>there is only one domain name in one record, but ther could be multiple ips for it. You can consider the record as a dns packet.</p> <p>I want to group records depending on llweb_result (0,1,2). I will do a selection query for them(e.g. I fetch records which contains '1'). But for the example above, there will be two identical tuples in the result.</p> <p>Any help will be appriciated. </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.
