Serializing a dictionary that is not a model in Django restframework

I have read a few answers and posts about serializing an dictionary . But I still can't get it to work. Here is the problem. I do some data processing in django app , and it returns this dictionary (It has information about a quiz):

{101: {'subject': 'General-Intelligence', 'topics': ['Coding Decoding', 'Dice & Boxes', 'Statement & Conclusion', 'Venn Diagram', 'Mirror and Water Image', 'Paper Cutting and Folding', 'Clock/Time', 'Matrix', 'Direction', 'Blood Relation', 'Series Test', 'Ranking', 'Mathematical Operations', 'Alphabet Test', 'Odd one out', 'Analogy'], 'num_questions': 25, 'creator': 'Rajesh K Swami'}}

I want to serialize this dictionary. So what I have done is created a class for this dictionary. ie.

class PsudoTests:

def __init__(self,body):
self.body = body

Also a serializer:

class PsudoTestSerializer(serializers.Serializer):
body = serializers.DictField()

Now in api view :

class TestListView(generics.ListAPIView):
def get_serializer_class(self):
serializer = PsudoTestSerializer
def get_queryset(self):
me = Studs(self.request.user)
tests = me.toTake_Tests(1) # this method brings in the above dictionary that i want to serialize
p_test = PsudoTests(tests) #this creates an instance of class created above

return p_test

Now when i go to the url there is a key error:

"Got KeyError when attempting to get a value for field body on serializer PsudoTestSerializer.\nThe serializer field might be named incorrectly and not match any attribute or key on the dict instance.\nOriginal exception text was: 'body'."

Why use threads in Python?

I just learned about the GIL and from the looks of it, it appears even if we use threads in python, our program will take the same time if we just use a single thread due to GIL. If that's the case, using threads for performance isn't really the ideal use case in python, so why use it?

Pyforms: Embedding a pyplot into a pyForm using ControlMatplotlib

I have come across the ControlMatplotlib control, however I cannot for the life of me figure out how to pass the pyplot to this control.

There is little to no example code for the use of this control and the docs don't have example code.

Any insight is greatly appreciated.

[AF] Does anyone use webtest? If so, why use it over flask's built-in test client?

I've been learning unit/integration testing following [sloria/cookiecutter-flask](https://github.com/sloria/cookiecutter-flask) as an example. I know this approach is opinionated, but does anyone know what value webtest brings over flask's built-in test client? I'm relatively new to flask but I suspect that the author simply prefers using webtest (perhaps since it's a more general tool).

Allowing user to add details to flask-mail message

So I have a modal on my site from which I want my user to be able to enter their email, hit submit, and then the app to message me with the users email. So far I've got the site sending a message but I'm unsure how to get the users email into the message. Any help would be much appreciated.

My code for sending the email

@app.route('/sendmail/', methods=['POST','GET'])
def send_mail():
try:
#emaiil = request.form['email']
msg = Message("Access request",
sender="SENDING_EMAIL",
recipients=["MY_EMAIL"])
msg.body = "Users email is"
mail.send(msg)
flash('Request sent!')
return redirect(url_for('main'))
except Exception, e:
return(str(e))

My modal for which the user enters their email

<div class="modal-body">
<p>Password can be obtained from somewhere</p>
<form action="{% print url_for('send_mail') %}" class ="form- inline" method="post">
<input type = "email" class = "form-control" placeholder="Email" name = "email">
<a href="/sendmail" class ="btn btn-default">Submit</a>
<button type="button" class="btn btn-secondary" data- dismiss="modal modal2">Close</button>
</form>

The modal is called from here

@app.route("/", methods=['POST','GET'])
def main():
return render_template('main.html')
