I have a form that holds multiple inputs... Within the request.POST, I'm looping through all of the input values. But I'd like to store them within a variable.. How do I do that?
for key, value in request.POST.items():
print(key, value) # how can I store instead of print?
How can I store all values in a python array/dict/whatever?
You have couple of ways to store the POST data in a local variable. The question is: why would you want to do that when you have access to request.POST anyway?
# Note: all keys and values in these structures are strings
# easiest, but immutable QueryDict
d = request.POST
# dict
d = dict(request.POST.items())
# array
a = list(request.POST.items()) # list of key-value tuples
a = request.POST.values() # list of values only
These variables will only live for the current request-response cycle. If you want to persist any of the data beyond that, you would have to store them to the database. Moreover, I recommend using a django form to handle POST data. That will take care of validation, type-casting, etc. for you.
dict is most easily converted to JSON string via json.dumps(d). .values() does include hidden inputs!This might not directly answer your question, but I don't recommend accessing request.POST directly since you already had a form. Form is good that it abstracts away a lot of the raw data that you need to handle by encapsulating them in the form object, so I would suggest check the form itself for data:
form = YourForm(request.POST or None)
if form.is_valid():
field1_value = form.cleaned_data['field1']
field2_value = form.cleaned_data['field2']
django doc has examples about how to access form fields like I did.
Also, if you want to get a copy of mutable dict object same as request.POST, you could do:
post_copy = request.POST.copy()
request.POST which could be very painful.json.loads(json_string) to convert json string to python dict(like a hash in js).docs.python.org/2/library/json.htmljson.dumps(dict), or just use a shortcut JSONResponse in django: docs.djangoproject.com/en/1.9/ref/request-response/…
mydict = request.POST? ormydict = request.POST.copy()
