    <p>I'm sure this is a completely obvious beginner question, but trying to find answers to beginner Ruby questions on google is turning out to be an exercise in futility.</p> <p>Anyway, suppose I have a database table that looks like this:</p> <pre><code>MyMessage ================== int :id string :from string :to string :messagetext </code></pre> <p>Now, if I need to expose a URL that takes in querystring params in the form of:</p> <blockquote> <p><a href="http://mysite.com/?sender=alice&amp;receiver=bob&amp;message=Hello" rel="nofollow noreferrer">http://mysite.com/?sender=alice&amp;receiver=bob&amp;message=Hello</a></p> </blockquote> <p>What is the best way to map the querystring params to my model?</p> <p>Right now, I'm just doing it by brute force inside the controller:</p> <pre><code>@sender = params[:sender] @receiver = params[:receiver] @message = params[:message] @mymessage = MyMessage.new @mymessage.from = @sender @mymessage.to = @receiver @mymessage.messagetext = @message @mymessage.save </code></pre> <p>My guess is that I should be able to create a class representing this type of querystring request, i.e.</p> <pre><code>class Request attr_accessor :from attr_accessor :to attr_accessor :message end </code></pre> <p>Then use some RoR magic to create the <code>Request</code> object from the <code>params</code> and then more magic to create a method that maps the <code>Request</code> object to the <code>MyMessage</code> object.</p> <p>Any suggestions? Does this make sense at all?</p>

    1. COThis is covered in pretty much every one of the 'my-first-Rails-app' tutorials. Have you done one?

    2. COYes, I've done about four of them. Are you sure you understand the question? If you can post a link showing a tutorial where I missed this, I'll happily delete the question. I think I can do it through update_attributes, but the question is marked 'newbie' for a reason.

    3. COYes, I did create the sample apps. None of them seem to address creating custom classes and mapping them to a generic Model, though. Not trying to be a jerk either, but do you understand that the Model/DB had different field names/properties than what's being passed in via the querystring?

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.
