lizard-map 1.87

Core concept: workspaces

A workspace item is something that can be displayed on a map. A workspace is a collection of workspace items that is actually displayed.

Every session gets its own workspace. (There is a possiblity of adding extra workspaces, but that isn’t used yet in one of our sites, so it isn’t fully thought-out yet).

A workspace item needs to know how to display itself, how to search for items when you click on the map and more. To get that to work for arbitrary map sources, you need to configure an adapter. The adapter has a layer() method for returning a mapnik layer, a search() method for searching and so on.

• You register an adapter as a so-called “setuptools entrypoint” under a specfic name.

• When you add a workspace item, you pass in the adapter name and an optional snippet of json to configure the adapter.

The workspace item keeps track of this adapter and its configuragion and uses it to generate maps, for searching, etc.

Collages

A workspace item often results in multiple areas or points. If you click on such a point, you normally get a popup with extra information. If you want to compare a couple of those information “snippets”, you can place them in your workspace’s collage.

Clicking the collage gives a popup with all the collected information popups in that single popup.

Interaction

Included is quite some javascript for workspace interaction. Potential workspace items can be drag/dropped into a workspace to add them. Workspace items can be reordered. You can drag them to the trash.

Dependencies

Almost all dependencies are listed in our setup.py, so they get pulled in automatically. Not all of them install as good as eggs, though. You might be better off installing them system-wide with your OS’s own packaging system.

You can force buildout to use system-wide installed packages with the osc.recipe.sysegg recipe. An example config:

[buildout]
...
parts =
    sysegg
    ...

[sysegg]
recipe = osc.recipe.sysegg
force-sysegg = true
eggs =
    PIL
    matplotlib
    simplejson
    pyproj

Development installation

The first time, you’ll have to run the “bootstrap” script to set up setuptools and buildout:

$> python bootstrap.py

And then run buildout to set everything up:

$> bin/buildout

(On windows it is called bin\buildout.exe).

You’ll have to re-run buildout when you or someone else made a change in setup.py or buildout.cfg.

The current package is installed as a “development package”, so changes in .py files are automatically available (just like with python setup.py develop).

If you want to use trunk checkouts of other packages (instead of released versions), add them as an “svn external” in the local_checkouts/ directory and add them to the develop = list in buildout.cfg.

Tests can always be run with bin/test or bin\test.exe.

External dependencies

The dependencies for a full website that uses lizard-map are best expressed as ubuntu/debian package dependencies: build-essential, python2.6-dev, apache2, libjpeg-dev, python-imaging, python-matplotlib, python-mapnik, python-scipy, libapache2-mod-wsgi, python-gdal, spatialite-bin, python-pysqlite2, python-pyproj.

Site integration

The following steps has to be done in order to use the lizard_map/workspace concepts.

• Install lizard-map somewhere. (Add ‘lizard-map’ in your setup.py: install_requires)

• Add ‘lizard_map’ to your settings.py: INSTALLED_APPS.

• Add ‘lizard_map.context_processors.processor.processor’ to your settings.py’s TEMPLATE_CONTEXT_PROCESSORS. REQUIRED for all map related functionality.

• Add an entry in your urls.py:

  (r'^map/', include('lizard_map.urls')),

• On your page, include the following parameters:

  • javascript_hover_handler (popup_click_handler)

  • javascript_click_handler (popup_hover_handler)

  • date_range_form

  • workspaces

Example view:

from django.shortcuts import render_to_response
from django.template import RequestContext

from lizard_map.daterange import DateRangeForm
from lizard_map.daterange import current_start_end_dates
from lizard_map.workspace import WorkspaceManager


def homepage(request,
             javascript_click_handler='popup_click_handler',
             javascript_hover_handler='popup_hover_handler',
             template="lizard_shape/homepage.html"):
    """
    Main page for Shape.
    """

    workspace_manager = WorkspaceManager(request)
    workspaces = workspace_manager.load_or_create()
    date_range_form = DateRangeForm(
        current_start_end_dates(request, for_form=True))

    return render_to_response(
        template,
        {'javascript_hover_handler': javascript_hover_handler,
         'javascript_click_handler': javascript_click_handler,
         'date_range_form': date_range_form,
         'workspaces': workspaces},
        context_instance=RequestContext(request))

Example template:

{% extends "lizard_map/wms.html" %}
{% load workspaces %}

{% block subtitle %} (page name) {% endblock %}

{% block sidebar %}

<div id="iconbox" class="sidebarbox sidebarbox-stretched iconlist">
  <h2>Apps</h2>
  <ul>
      <li>
        <a href="/address/" class="lizard-map-link">
          <img src="{{ STATIC_URL }}lizard_ui/app_icons/meetgegevens.png" />
          <div>App</div>
        </a>
      </li>
  </ul>
</div>

{% for workspace in workspaces.user %}
  {% workspace workspace %}
{% empty %}
No workspace
{% endfor %}

{% endblock %}

• Add this view to your views.py:

  (r’^$’, ‘mapdemo.views.homepage’),

• Start testing by running syncdb.

• Add and configure background maps by loading “background_maps” fixture.

• Start dev server.

Settings

Some default date range settings can be set in settings.py. All settings are optional:

START_YEAR = 2000  # Defaults to today - 7 years
END_YEAR = 2010  # Defaults to today + 3 years.

# Define default period 1..5
# From daterange.py:
# PERIOD_DAY = 1
# PERIOD_TWO_DAYS = 2
# PERIOD_WEEK = 3
# PERIOD_MONTH = 4
# PERIOD_YEAR = 5
# PERIOD_OTHER = 6

DEFAULT_PERIOD = 5  # Defaults to 1

# If DEFAULT_PERIOD = 6, define these
DEFAULT_START_DAYS = -20  # Defaults to -1000
DEFAULT_END_DAYS = 1  # Defaults to 10

1.87 (2011-06-17)

• Re-enabled custom y tick locator amount selection.

• Showing the table now looks at the table belonging to the button by means of a wrapper div, which is more reliable.

1.86 (2011-06-16)

• Added bare try/except around wms workspace layer looping to prevent the function to crash.

• Added transparency_slider to context variables. From now on the transparency_slider is enabled by default.

• Use updated krw shapefiile.

• Use different open street map.

1.8 (2010-08-30)

• Bugfix for when no statistics are available.

1.7 (2010-08-27)

• Graph and collage popups now use the “regular” jquerytools popup instead of the OpenLayers in-the-map popup. Visually cleaner, clearer and prettier. And easier to maintain and to get right.

• Various visual fixes.

• Deleting a workspace item also deletes the corresponding snippets.

• Added color pulldown for collage view settings (instead of requiring you to know the internal matplotlib color code names :-) )

1.6 (2010-08-26)

• Animation slider and name-hover are now also working in the default workspace view.

• Name hover is now placed just to the lower right of the cursor. This way you can still click on the item you hovered above instead of your click being blocked sometimes by the hovering name.

1.5 (2010-08-26)

• Added tooltips with name when hovering over clickable map items.

• Layout improvements for popups and tables.

• Added dateperiods: calculate periods for use in graphs.

• Added styling for popups.

1.4 (2010-08-23)

• WorkspaceCollageSnippetGroup’s name was a TextField (=multiline) instead of a simple CharField. Oracle stores a TextField as a “NCLOB” and has some restrictions on them (no index, no .distinct()). Anyway, this blew up on an oracle-using installation. Fixed now.

• Removed double value_aggregate() method from base adapter: the extra one raised a NotImplemented error and overshadowed the real method.

1.3 (2010-08-18)

• Requiring our dependencies that must be installed with system eggs. We use the osc.recipe.sysegg in our own buildout to grab them from the system. A sample config is included in the readme.

• Implemented snippet groups. Snippet groups group similar snippets in a collage.

• Removed site-specific breadcrumbs.

• Refactored collage view. One can now edit graphs in the collage view. The graph-only editor has been removed.

• Added an animation slider for showing map layers at specific points in time. Only shown when there are workspace items that support it.

• Removed graph-properties that were stored in the session.

• Passing extra ‘request’ keyword argument to all adapter layer() methods. Warning: This needs refactoring in all adapters. Advance warning: we’ll probably refactor the adapters to get the request in their __init__() method later on.

1.1 (2010-07-16)

• Changed json decode behaviour: keys are now strings, not unicode.

1.0 (2010-07-15)

• Added global graph settings.

0.10 (2010-06-22)

• Popup (upon map click) shows popup when nothing’s found.

• More feedback (hourglass pointer and so).

0.9 (2010-06-18)

• Fixed wms.html’s javascript code: long live jslint!

• Not emptying the temp workspace anymore: it was happening too often. Now it isn’t happening often enough, though. Will be fixed later.

0.8 (2010-06-18)

• Using lizard-ui’s new css/javascript blocks.

• Copied charts from krw here.
