Simple Password Confirmation using Django Forms (v1.10)
I need to implement a very simple password confirmation in Django that will allow the user to enter a value in an input field. Template <form class="form-inline" method="POST" action="{% url 'details' %}"> {% csrf_token %} {{ form.tact_password }} {{ form.tacttime }} <br> <button type="submit" class="btn btn-outline-primary" value="submit">Submit </button> </form> Forms.py from django import forms class TactForm(forms.Form): tact_password = forms.CharField(widget=forms.PasswordInput( attrs = { 'class' : 'form-control mb-2 mr-sm-2 mb-sm-0', 'placeholder' : 'Enter Password:', 'id' : 'inlineFormInput' } ),label='Tact Password', max_length=100) Let's say my predefined password is HelloWorld, and I would like the user to be able to submit the form if his password matches HelloWorld. Many questions I found like this, involve checking two different input fields and seeing if they match, which is a different scenario. Can a similar method be used or is there a more efficient way? -

Cloud Text Editor
I am relatively new for world of web-based-coding and I got a long-term project to build a software which is a web-based text editor. Later, this software will use a db that will be built and used to be read and stored to. I looked some guides to build such software but lack of clues. Preferably, I want to use powerful (or at least a good start for learning web service) frameworks for front-end and back-end (if this is needed). I've looked for Angular , Symfony , and Django. I'm looking for a suggestion or critics or advices, where should I start from, in order to build this software. I appreciate for the help. Thank you very much. -

Building a geographical location filter app in Django
I would like to create a market place like app with Djano as the backend server, where users can buy/sell items. In the app I would like have to a feature related to geographic region of a user. Such as, to filter out items in a given specific miles of radius. Example use case: User uploads an item, get the gps cordinates from their mobile and store in db. User can search item, also filter to only get items in X miles radius. For this feature I have looked at GeoDjango. But it seems like I need to extend the postgresql database to use it, also by using the postgis engine. I have also looked at the Haversine formula for nearby queries. There is also an option for multiple database support. But I have some initial doubts before proceeding and your insights would really help me alot. Could you please help me with this queries: I will have to store user data and some other data including the geo location.

List Serializer multiple object creation
My Models class User(models.Model): id = models.AutoField(primary_key=True) email = models.EmailField() class Lawyer(models.Model): user = models.OnetoOneField(User) class Session(models.Model): name = models.CharField() lawyer = models.ForeignKey(Lawyer) I am trying to create multiple objects with a list serializer for Session table, From the appside they don't have the id of lawyer but has the email of each lawyer. How can I write a listserializer where I can take the following json input and use email to fetch lawyer to store multiple session objects? The json input sent will be like [ { "name": "sess1", "email": "lawyer1@gmail.com", }, { "name": "sess1", "email": "lawyer1@gmail.com", }, ]
