Macports died with an error

Error: Unable to open port: invalid command name "livecheck.type"
livecheck.type seems to be a new command in Macports 1.8.0. Upgrading to Macports 1.8.0 solves the problem.

To upgrade use

sudo port selfupdate


Dont forget you’ll need to install Xcode or you’ll get this error message

configure: error: in `/opt/local/var/macports/sources/rsync.macports.org/release/base':

<% form_for(@post) do |f| %>

    <%= f.label :title %><br />
    <%= f.text_field :title %>

    <%= f.label :source %><br />
    <%= select_tag :source,  options_for_select([ "Dog", "Cat") %>

    <%= f.submit 'Create' %>

<% end %>

I finally got this to work by using;

1

<%= f.select(:source, options_for_select({ : Dog =>'Dog',:Cat =>'Cat'} %>

If you put the options in a hash then they will be output in a random order, to output the options in a chosen order they need to be put into an array, this left me with the following code.

View

1
2

<%= f.label :source %><br />
<%= f.select(:source, options_for_select(@source)) %>

Controller

1

@source = [['Dog'],['Cat'],]

This is the index.html file and jQuery code, its pretty simple, I was just testing that I could get a valid connection, then parsing the XML within artist-list and outputting anything that has the XML tag name

One question that might arise from looking at this code is why the url is hosted at warez-dnb, jQuery wont let you import XML from a remote web host, it has to be from the local server, i’ve written an extremely simple PHP function that will query musicbrainz and copy the result it gets to host it locally.

<?php
// Set your return content type
header('Content-type: application/xml');

// Website url to open
$daurl = 'http://musicbrainz.org/ws/1/artist/?type=xml&name=' . $_GET["name"];

// Get that website's content
$handle = fopen($daurl, "r");

// If there is something, read and return
if ($handle) {
    while (!feof($handle)) {
        $buffer = fgets($handle, 4096);
        echo $buffer;
    }
    fclose($handle);
}
?>
