This QueryDict instance is immutable

Question

I have a Branch model with a foreign key to account (the owner of the branch):

class Branch(SafeDeleteModel):
    _safedelete_policy = SOFT_DELETE_CASCADE
           


        

Answer 1

As you can see in the Django documentation:

The QueryDicts at request.POST and request.GET will be immutable when accessed in a normal request/response cycle.

so you can use the recommendation from the same documentation:

To get a mutable version you need to use QueryDict.copy()

or ... use a little trick, for example, if you need to keep a reference to an object for some reason or leave the object the same:

# remember old state
_mutable = data._mutable

# set to mutable
data._mutable = True

# сhange the values you want
data['param_name'] = 'new value'

# set mutable flag back
data._mutable = _mutable

where data it is your QueryDicts
