How To Pass Argument Name As A Parameter?

I have this code: hobbies2 = form.cleaned_data.pop('hobbies2') PersonneHobby.objects.filter(personne=obj).delete() for pk_str in hobbies2: try: hobby = TagTraduit.objec

Solution 1:

You could do it with an arbitary number of keyword-arguments (**) and insert calculated additional parameters inside the function:

def update_field(field, update_this, **kwargs):
     ...
     kwargs[update_this] = TagTraduit.objects.get(pk=int(pk_str))
     p = field.objects.create(**kwargs)
     ...

this allows you to call it like that:

update_field(PersonneHobby, 'hobby', personne=obj)
update_field(PersonneProgramme, 'programme', personne=obj)

Solution 2:

You can do this:

def update_field(..., field_name):
   ...
   tag = TagTraduit.objects.get(pk=int(pk_str))
   p = PersonneProgramme.objects.create(**{'personne': obj, field_name: tag})

Solution 3:

I will go with what @MSeifert said. If you want whatever you have written to work, I mean with positional arguments alone.

def f(a,b,c):
    a.func(b=b,c=c)# this is perfectly legal

But the better way to go about it is,

deff(a, **kwargs):
    a.func(**kwargs)  # kwargs is passed as a dict. **kwargs is# unpacking it into key1=val1, key2=val2, ...
