Hi,
I think you have a misconception in your model. What you need is a many to
many relation so it does not matter how many metabolites each Reaction has.
I am not so fimilar with Chemistry. So each stoichiometry belongs to
exactly one metabolite?
if yes you could create an additional Model call it for example
StoichiometryMetabolite which has three fields:
stoichiometry = models.CharField(max_length=255, blank=True, null=True)
metabolite = models.ForeignKey('Metabolites', on_delete=models.CASCADE)
reaction = models.ForeignKey('Reactionsmeta', on_delete=models.CASCADE
In your admin.py you have to create an InlineAdmin for
StoichiometryMetabolite:
class StoichiometryMetaboliteInline(admin.StackedInline):
model = StoichiometryMetabolite
extra = 6
Than you have to add it to your inlines in your Reactionsmeta admin
inlines = [StoichiometryMetaboliteInline
Everytime you have numbered columns in your model you should consider
refactor it since it is not good database design.
