[GeoNode-devel] GeoNode Project: Timeout updates Layer with new ManyToManyField in ResourceBase

[Giambattista Mameli]

Hi guys,
I developed a custom GeoNode Project implementing a M:M relationship on the
ResourceBase table

Here the steps:

1) model creation of the new table

class DomainArea(models.Model):
    identifier = models.CharField('Domain Area name', max_length=255,
unique=True)
    description = models.TextField(default='')
    gn_description = models.TextField(
        'GeoNode description', default='', null=True)
    is_choice = models.BooleanField(default=True)

    def __unicode__(self):
        return u"{0}".format(self.gn_description)

    class Meta:
        ordering = ("identifier",)
        verbose_name_plural = 'Domain Areas'

2) add the relation between the ResourceBase table and the new created table

        domainarea = models.ManyToManyField(
            DomainArea,
            related_name='resourcebase_domainarea',
            blank=True)
        ResourceBase.add_to_class('domain_area', domainarea)

3) Add the function to handle the new value in the admin panel

admin.site.register(DomainArea)

All the steps work good, Django creates the new table with all the
relationship and I can handle via admin panel both values and associations
between domain areas and Layers/Docs/Maps.

The problem is when I modify these values.

After the first association, all the updates go wrong (timeout, even with a
very long timeout set).

This is the error message:

Any help will be greatly appreciated
