    <p>This is how method <code>authenticate_or_request_with_http_basic</code> and in general how HTTP authentication works. <code>authenticate_or_request_with_http_basic</code> can be reworded as: "First try to authenticate and if not authenticated, request for authentication". The source code of this method is as follows:</p> <pre><code>def authenticate_or_request_with_http_basic(realm = "Application", &amp;login_procedure) authenticate_with_http_basic(&amp;login_procedure) || request_http_basic_authentication(realm) end </code></pre> <p>So what happens. When you first hit the URL that invokes this action, this <code>authenticate_or_request_with_http_basic</code> returns HTTP response 401 Unauthorized. The browser understands this is a request for authentication and shows you a dialog to enter username and password, and then resends the request for the same URL but includes your credentials into request headers. You filter is hit again, and this time method <code>authenticate_or_request_with_http_basic</code> sees that there are authentication headers in the request and authorises you successfully. And the browser will send these auth headers on each following request to this domain (until you close the browser).</p> <p>So if you need just test it several times you can close and reopen browser. I believe using only these methods it is impossible to ask for authentication and authenticate on every request because when the application gets request from browser with Auth headers it can not tell whether this is request immediately after authentication request, or these are headers preserved before.</p> <p>But this can be somehow accomplished using cookies or value stored in session.</p>

    1. COthank you so much for your answer, but i don't understand how to use request_http_basic_authentication(realm). what's realm? how i can control the inserted nickname and password? i would to write something like this: authenticate_or_request_with_http_basic do |nick, pass| nick == user.nickname and pass == user.password end but using request_http_basic_authentication(realm)

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.
