    <p>I feel like I'm missing something very, very fundamental, so, to avoid tearing out more hair, I come here to ask why p1, p1t and p1t2 are getting modified on with "hand = newgame.view p1". I don't even know why p1 is getting modified, so yeah I'm totally baffled here. Any help would be tremendously appreciated. </p> <pre><code># encoding: utf-8 class Cards def view hand x = 0 hand.each do |card| if card[0] == 's' card[0] = '♠' elsif card[0] == 'd' card[0] = '♦' elsif card[0] == 'h' card[0] = '♥' elsif card[0] == 'c' card[0] = '♣' else #nil end hand[x] = card x = x + 1 end prettyhand = '' hand.each do |card| prettyhand = prettyhand + card[0] + card[1] + ' ' end return prettyhand end#view end#Cards ########### deck = 0 up = 0 p1 = 0 p2 = 0 newgame = Cards.new p1 = [["c", "4"], ["s", "4"], ["d", "q"], ["c", "8"], ["s", "5"], ["s", "q"], ["h", "3"], ["c", "10"]] p1t = [] p1t2 = [] hand = '' p1.each do |card| p1t.push card end p1t.each do |card| p1t2.push card end p '----------------------------------' p 'fresh p1:' p p1 p p1t p p1t2 hand = newgame.view p1 p 'unfresh p1:'#why is this changing?? p p1 p p1t p p1t2 p '----------------------------------' </code></pre> <p>output:</p> <pre><code>"----------------------------------" "fresh p1:" [["c", "4"], ["s", "4"], ["d", "q"], ["c", "8"], ["s", "5"], ["s", "q"], ["h", "3"], ["c", "10"]] [["c", "4"], ["s", "4"], ["d", "q"], ["c", "8"], ["s", "5"], ["s", "q"], ["h", "3"], ["c", "10"]] [["c", "4"], ["s", "4"], ["d", "q"], ["c", "8"], ["s", "5"], ["s", "q"], ["h", "3"], ["c", "10"]] "unfresh p1:" [["♣", "4"], ["♠", "4"], ["♦", "q"], ["♣", "8"], ["♠", "5"], ["♠", "q"], ["♥", "3"], ["♣", "10"]] [["♣", "4"], ["♠", "4"], ["♦", "q"], ["♣", "8"], ["♠", "5"], ["♠", "q"], ["♥", "3"], ["♣", "10"]] [["♣", "4"], ["♠", "4"], ["♦", "q"], ["♣", "8"], ["♠", "5"], ["♠", "q"], ["♥", "3"], ["♣", "10"]] "----------------------------------" </code></pre>

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.
