    <p>I am learning to user <code>PostgreSQL</code> and <code>Django</code> together in Ubuntu 11.10, and I have found that I need to switch to the user I created when I installed PostgreSQL (<code>"postgres"</code>) in the Terminal (via <code>"sudo su postgres"</code>) in order to create and then access databases to work with in Django. Unfortunately, the <code>"postgres"</code> user doesn't have file writing privileges on my local file system, so when I try to do certain things like add model objects to the database that have an image field, I'm blocked. But if I switch to my normal Ubuntu user name in the Terminal and try to access my admin site on Django's dev server, I get an error like this:</p> <pre><code>OperationalError at /admin/ FATAL: Peer authentication failed for user "postgres" Request Method: GET Request URL: http://127.0.0.1:8000/admin/ Django Version: 1.3.1 Exception Type: OperationalError Exception Value: FATAL: Peer authentication failed for user "postgres" Exception Location: /usr/local/lib/python2.7/dist-packages/django/db/backends/postgresql_psycopg2/base.py in _cursor, line 140 Python Executable: /usr/bin/python Python Version: 2.7.2 </code></pre> <p>I'm trying to read up on the PostgreSQL docs to give my normal user access to the databases I've created for my Django projects, but I can't figure it out because I don't understand the relationship between PostgreSQL roles/users and Ubuntu users. Could someone please explain to me how I can give my normal Ubuntu username access to my databases in PostgreSQL? I will probably need a specific list of instructions as I've tried to piece it together using the PostgreSQL docs and I'm totally lost.</p>

    2. COIt's not clear what you're really trying to do here. If an object is managed by the database engine, you normally want to access that object through your database connection, not directly. What are you trying to do when you get this error?

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.
