I wanted to know to to use the PointField widget that is automatically generated from a Django form.
I am using the generic views for this (CreateView)
This is what my model looks like.
from django.contrib.gis.db import models
class Post(models.Model):
title = models.CharField(max_length=60)
text = models.CharField(max_length=255)
location = models.PointField(geography=True, null=True, blank=True)
objects = models.GeoManager()
The form is then automatically generated for me and I just call it in my view. As such:
{{ form.as_p }}
This is the output of that piece of code.
<form method="post">
<input type='hidden' name='csrfmiddlewaretoken' value='wVZJIf7098cyREWe3n3jiZinPdbl8nEe' />
<p><label for="id_title">Title:</label> <input id="id_title" maxlength="60" name="title" type="text" /></p>
<p><label for="id_text">Text:</label> <input id="id_text" maxlength="255" name="text" type="text" /></p>
<p><label for="id_location">Location:</label> <style type="text/css">
#id_location_map { width: 600px; height: 400px; }
#id_location_map .aligned label { float: inherit; }
#id_location_div_map { position: relative; vertical-align: top; float: left; }
#id_location { display: none; }
.olControlEditingToolbar .olControlModifyFeatureItemActive {
background-image: url("/static/admin/img/gis/move_vertex_on.png");
background-repeat: no-repeat;
}
.olControlEditingToolbar .olControlModifyFeatureItemInactive {
background-image: url("/static/admin/img/gis/move_vertex_off.png");
background-repeat: no-repeat;
}
</style>
<div id="id_location_div_map">
<div id="id_location_map"></div>
<span class="clear_features"><a href="javascript:geodjango_location.clearFeatures()">Delete all Features</a></span>
<textarea id="id_location" class="vSerializedField required" cols="150" rows="10" name="location"></textarea>
<script type="text/javascript">
var map_options = {};
var options = {
geom_name: 'Point',
id: 'id_location',
map_id: 'id_location_map',
map_options: map_options,
map_srid: 4326,
name: 'location'
};
var geodjango_location = new MapWidget(options);
</script>
</div>
</p>
<input type="submit" value="Create" />
</form>
In the head tags I import an OpenLayers script from http://cdnjs.cloudflare.com/ajax/libs/openlayers/2.13.1/OpenLayers.js
However, the page will not show anything for the pointfield. (The other fields work just fine).
In chromedevtools it shows this error
Uncaught ReferenceError: MapWidget is not defined
For this line of code
var geodjango_location = new MapWidget(options)
Basically I want to know if there is someother javascript library I should be linking to or am I missing something else?
I've looked through the documentation on GeoDjango forms, but don't know what else to try https://docs.djangoproject.com/en/dev/ref/contrib/gis/forms-api/

The SRID is an integer specifier that corresponds to the projection system that will be used to interpret the data in the spatial database. [3] Projection systems give the context to the coordinates that specify a location.
GeoDjango is an included contrib module for Django that turns it into a world-class geographic web framework. GeoDjango strives to make it as simple as possible to create geographic web applications, like location-based services. Its features include: Django model fields for OGC geometries and raster data.
Add this to the head section:
<head>
{{ form.media }}
