I am currently working on django. I created 4 classes in models.py, one of
them is ReactionMeta class. This class has 62 columns, which defined as
below:
class Reactionsmeta(models.Model):
id = models.ForeignKey('Reactions', db_column='id', primary_key=True,
max_length=255, on_delete=models.CASCADE)
name = models.CharField(max_length=255, blank=True, null=True)
metabolite1 = models.ForeignKey('Metabolites', db_column='metabolite1',
blank=True, null=True,
on_delete=models.CASCADE)
stoichiometry1 = models.CharField(max_length=255, blank=True, null=True)
metabolite2 = models.ForeignKey('Metabolites', db_column='metabolite2',
blank=True, null=True,
on_delete=models.CASCADE, related_name='+')
stoichiometry2 = models.CharField(max_length=255, blank=True, null=True)
metabolite3 = models.ForeignKey('Metabolites', db_column='metabolite3',
blank=True, null=True,
on_delete=models.CASCADE, related_name='+')
stoichiometry3 = models.CharField(max_length=255, blank=True, null=True)
metabolite4 = models.ForeignKey('Metabolites', db_column='metabolite4',
blank=True, null=True,
on_delete=models.CASCADE, related_name='+')#...
Some of the reactions, may have 6 metabolites, like 2a + b + c -> 3d + e + f
however, some of reactions may only have 2 metabolites and stoichiometries,
like a -> 2c
which means there is no value of this reaction in
metabolite3,4,5,6...columns and stoichiometry 3,4,5,6...columns.
In that case, how can I only display the Charfield with data while
undisplay those Charfield with no value in django-admin?
