Russel:
Thanks for your attention. I send you an example
Assuming the model:
class Tab1(models.Model):
data1 = models.CharField(maxlength=10)
data2 = models.CharField(maxlength=50)
data3 = models.BooleanField(default=False)
data4 = models.ManyToManyField('self', null=True, blank=True,
filter_interface=models.HORIZONTAL, related_name='docrel',
limit_choices_to={'data3__exact': True})
After filling data, I have next result:
--------------------------------------------------------------------------
Data1 Data2 Data3 Data4
--------------------------------------------------------------------------
Boss Maria X Fredo, Pepe, Sue
Boss Jose X Anthony, Carla
Boss David X Robert,Mike
Employee Fredo Maria
Employee Pepe Maria
Employee Carla Jose
Employee Anthony Jose
Employee Sue Maria
Employee Robert David
Employee Mike David
But some steps before, Assuming I created the first five records only,
screen for creation of Carla will show:
Data2 ->: Carla
Data4 ->:Choice Maria, Jose or David (only 3 are shown in data4
because of the Data3 field condition where X is true)
After completion of data fill, If for example, instead of Fredo, I
change to Frido, the final result will be:
----------------------------------------------------------------------
Data1 Data2 Data3 Data4
----------------------------------------------------------------------
Boss Maria X Pepe, Sue
Boss Jose X Anthony, Carla
Boss David X Robert,Mike
Employee Frido
Employee Pepe Maria
Employee Carla Jose
Employee Anthony Jose
Employee Sue Maria
Employee Robert David
Employee Mike David
The relation of Frido to Maria and Maria to Frido (symmetrical=True by
default) dissapeared!! It is important to say that Data2 is not primary
key.
That is my problem.
Very, very best regards
