map that has already been displayed in the browser. (If this is the first invocation, it will refer to the default extent.) 046 old_extent = mapscript.rectObj() Line 047 defines the default extent as an array. The values of the array elements are the extent coordinates specified in the mapfile. On first invocation, this is the extent that will be saved on the web page as a hidden variable. Subsequent invocations will assign current values to the coordinates. Line 048 defines the maximum extent of the map the MapScript zoomPoint() method employed in the following code won t zoom out farther than this. This extent should also equal the extent specified in the mapfile, or else strange behavior will occur. 047 extent = (-180.0, 0.0, -60.0, 90.0) 048 max_extent = mapscript.rectObj(-180.0, 0.0, -60.0, 90.0) Line 051 creates a CGI object referenced by parms. As mentioned previously, the CGI method FieldStorage() is used to retrieve form values. 051 parms = cgi.FieldStorage() Line 054 creates a new mapObj map based on the contents of the mapfile specified previously (i.e., third.map). The extent of this map is the extent specified in the mapfile, and the layers rendered are those for which the STATUS is on or default. 054 map = mapscript.mapObj(map_path+map_file)

Lines 057 and 058 determine whether the script has been invoked by a form or not. All the code up to this point is executed every time the script runs, and default values have been assigned to most variables. If the script has been invoked by the form, then the CGI method parms.getfirst() will return the value of its argument string. The block of code following the if statement will then be executed. 057 if (parms.getfirst('img.x') and parms.getfirst('img.y')) \ 058 or parms.getfirst('refresh'): If the script hasn t been invoked by a form, the if conditional will evaluate to False and execution will drop through to Line 142 without executing any conditional code. Let s assume that this is the first invocation so that execution falls through. Line 142 creates a unique identifier for the various images associated with this map by formatting a random number as a six-digit string. Lines 143 through 148 define file names and URLs for the map image, the reference map image, and the legend image. 142 143 144 145 146 147 148 map_id = str(random.randrange(999999)).zfill(6) image_name = "pythird" + map_id + ".png" image_url="/tmp/" + image_name ref_name = "pythirdref" + map_id + ".gif" ref_url="/tmp/" + ref_name leg_name = "pythirdleg" + map_id + ".png" leg_url="/tmp/" + leg_name

Listing 3-35. Adding an association and validations to app/models/release.rb class Release < ActiveRecord::Base belongs_to :movie validates_presence_of :movie_id, :format, :released_on end In the controller, you ve got some work to do. First, you ll want to restrict release management (like user, person, and movie management before) to administrators only though anyone should be able to view the complete list. Since you ll need to select movies when creating or editing a release, you ll also need to add code to make sure that information is available to the views. Listing 3-36 shows the update. Listing 3-36. Updating app/controllers/releases_controller.rb class ReleasesController < ApplicationController before_filter :require_admin, :except => [:index] # ... # GET /releases/new # GET /releases/new.xml def new @movies = Movie.find(:all, :order => 'title').map {|m| [m.title, m.id]} @release = Release.new respond_to do |format| format.html # new.html.erb format.xml { render :xml => @release } end end # GET /releases/1/edit def edit @movies = Movie.find(:all, :order => 'title').map {|m| [m.title, m.id]} @release = Release.find(params[:id]) end # ... end Of course, adding the code to the controller leads to updating the autogenerated views to make use of them in your new and edit forms (which, to keep your code DRY, you may want to extract into a partial); Listing 3-37 shows the changes.

Note Reference map image types can only be in GD-based formats: GIF, PNG, and JPEG. Furthermore, the image type of the output image must be the same as the input image type specified in the REFERENCE object. Reference maps also ignore the image type specified in the IMAGEFORMAT object.

Line 151 uses the draw() method to create the map image. Finally, the map image is saved by the imageObj method save(). Lines 155 through 160 perform similar steps for creating and saving the reference map and legend images. 151 152 155 156 159 160 image=map.draw() image.save(img_path + image_name) ref = map.drawReferenceMap() ref.save(img_path + ref_name) leg = map.drawLegend() leg.save(img_path + leg_name)
