I'm trying to set up a many to many relationship, but when I save the model
I get "TypeError: 'layer_set' is an invalid keyword argument for this
function".
In class Experiment(Job) I declare the model with:
layer_set = models.ManyToManyField(LayerSet, blank=True, default =
"default layer")
In class ExperimentForm(forms.Form) I assign input with:
layer_set =
forms.ModelMultipleChoiceField(queryset=LayerSet.objects.all(),
widget=forms.CheckboxSelectMultiple, required = False)
In my views.py:
if request.method == "POST":
form = ExperimentForm(request.POST, request.FILES)
if form.is_valid():
experiment = Experiment(**form.cleaned_data)
experiment.owner = request.user
experiment.save()
The problem is occurring in experiment = Experiment(**form.cleaned_data).
The constructor for this is:
def __init__(self, *args, **kwargs):
kwargs = _append_type(kwargs)
super(Experiment, self).__init__(*args, **kwargs)
I believe the problem lies in super() trying to find a layer_set in
Experiment, which doesn't exist since layer_set needs to be a 2nd table that
points to Experiment and LayerSet. So far my best guess is that in views.py
I need to add something like:
if form.is_valid():
temp_layer_set = form.cleaned_data['layer_set'] <-----
del form.cleaned_data['layer_set']
<-----
experiment = Experiment(**form.cleaned_data)
experiment.owner = request.user
experiment.save()
(something to save temp_layer_set to its own table) <-----
But at this point I have no idea how to actually save the temp_layer_set. It
doesn't have its own class or anything so I can't call
experiment_layer_set.save().
