Key Error in form.cleaned_data

2019-08-08 Thread Mei B 
I'm using a formset, and i'm trying to iterate through all the cleaned 
data except I keep getting a Keyerror no matter what field I try..

for form in formset:
   data = form.cleaned_data
   name = data["name"]

--->  KeyError: "name"

class VariableForm(forms.Form):
name = forms.CharField()
default = forms.CharField(required=False)

Formset = formset_factory(
VariableForm,
can_delete=True,
extra=1,
)

What is wrong with my code?

I can even print(data) and it outputs:
 {'DELETE': False, 'name': 'PATH', 'default': '/opt/tests'}

I can even do, for key, value in data.items(): and output
delete false
   name PATH

Re: How to customize AdminWidget FilteredSelectMultiple?

2019-07-23 Thread Mei B 
I figured out how to customize what I want by editing SelectFilter2.js, 
located in /admin/js/SelectFilter2.js
My question now is, how do I get django to look at this new 
SelectFilter2.js instead of the original?
I thought I would pop it in my_app/static/admin/js/ but that doesn't seem 
to be working.

How to customize AdminWidget FilteredSelectMultiple?

2019-07-22 Thread Mei B 
I'm trying to use the admin widget FilteredSelectMultiple, I can get it to 
render on my page, but I want to customize it a bit more.

I want to change the labels from available/chosen, change the size, and 
reorder the boxes (have chosen be on the left) How do I go about doing that?

Order_by ManyToMany relation?

2019-06-05 Thread Mei B 
I have a form for a model that contains a ManyToMany relationship to model 
B.
By default, manytomany relationship on forms are SelectMuliple and orders 
them by alphabetical.
How can I order by if they already have a relation?

In my forms.py

class FormA(forms.ModelForm):
class Meta:
model = models.A

def __init___(self, *args, **kwargs):
  super(FormA, self).__init__(*args, **kwargs)
  self.fields["b"].queryset = models.B.objects.order_by(???)

If model B has objects: "a, a1, a2, b, b2"
And model A has a many to many relationship with B's "a, a2, b2"
How can I order the objects so it'll show "a, a2, b2, a1, b" on the form?

Legacy DB: ID is null when .save or .create

2019-05-17 Thread Mei B 
I'm using a legacy DB with postgres. In one of my models:

class case(models.Model):
 id = models.AutoField(primary_key=True)
 case_id = models.ForeignKey(.)
 user_id = models.ForeignKey(...)

When I'm saving or creating a new case object, I always get "null value in 
column 'id' violates not-null"

How do I get this to auto-increment?
