In the form field you are saving from, you write the form field value and then an empty space where the input value goes sort of like "form.cleaned_data.get("field name", " "). The second blank ""is the empty space where the field value goes. The claned_data is django's internal form validator. That sounds confusing so I'll give an example
This is what your views would look like
from django.shortcuts import render
from sample.models import Test
from sample.forms import TestForm
def Example(request):
if request.method == 'POST':
form = TestForm(request.POST)
if form.is_valid():
testmodel = Test()
testmodel.modelfield1 = form.cleaned_data.get('formfield1','')
testmodel.modelfield2 = form.cleaned_data.get('formfield2','')
testmodel.save()
return render(request, 'sample/nextpage.html')
else:
form =TestForm
context_data = {'form':form}
return render(request, 'sample/testformpage.html', context_data)I'm not sure I understand what you're saying here, but I don't think this is right. cleaned_data is a dictionary, and so the second argument to get is a default value to use if there is no value corresponding to the key. So, in your example, if there's no value for "formfield1" in cleaned_data, it would return a string with a space in.
This is probably not what you want to do. cleaned_data will always contain values for declared form fields, so the only way the default would be used is if you've made a mistake in specifying the key (for instance, if there's a typo and you've written 'formfeild1' instead of 'formfield1'). If you've made that kind of mistake, you don't want the program to continue using a single space instead of the valid data (you'll lose data) - you want the program to report that there's something wrong.
So I think you should probably use
form.cleaned_data['formfield1']
I just tried your solution with cleaned_data["formfield1"] instead of cleaned_data("formfield1","") and it didn't work for me, it came back with the following error message when I submitted the form:
>'builtin_function_or_method' object is not subscriptable
I think you have to have the empty quotes after the form field and I think that's what's capturing the user input
so here "form.cleaned_data("formfield1","") seems to be telling django the form name and then the second field is where the associated user input goes which is then passed to the model.
Works also with models with m2m fields with Form.save_m2m().
