What type files should be put into .gitignore file in Django project
From my other post, I know the __pycache__ should be put into the .gitignore when I use git. And in the other post I saw, there are also .pyc and .pyo files. whether them should all be put into the .gitignore file? Can we summarize in the Python/Django project, what files should be put into . gitignore file? -
Creating Single Page App in Django with Polymer
I'm currently working on a singe page app in django that makes use of Polymer Elements. My problem is when I'm changing template views. When I click on a page link to direct me to a new view I want to use the app-route, app-location and the iron-pages elements that Polymer has. This lets me simply change my current views without actually having to reload the whole page again and make requests. Apparently, in Django, whenever I click on a link it instead goes to the urls.py and tries to direct me to that link. Is it possible to create single page apps in django with polymer? -

Django - Pass a list item's id/pk to the view with jQuery ajax
Here is my code, shortened for brevity. HTML Template {% for question in questions %} <div class="upvote"></div> {% endfor %} # lots of code later... <script> $(".upvote").click(function(){ $.ajax({ type: "POST", url: "{% url 'upvote_for_question' %}", data: { 'question': question }, } }) }) </script> My <div class="upvote"> element is an upvote button for a question (think Stack Overflow's upvote button). As the code shows, every question in question_list has an upvote button. My question is, when the user presses an upvote button, how do I pass the associated question's pk/id to the view? -

differences between ModelSerializer.update() and ModelViewSet.update()
I found both ModelSerializer and ModelViewSet have update() method, and I think both are almost same. Is that correct ? from rest_framework import serializers from rest_framework import viewsets class FooSerializer(serializers.ModelSerializer): class Meta: model = Foo fields = '__all__' def update(self, instance, validated_data): # update of model instances instance.save() return instance class FooModelAPI(viewsets.ModelViewSet): serializer_class = MySerializer queryset = my_queryset def update(self, request, *args, **kwargs): # updateds model instances and save return Response("OK") In the above snippet, Can I use either ModelSerializer or ModelViewSet without another for updating model instance ? -

S3 upload fails in production (Python)
I'm trying to upload an XML file to S3 in my Django app. I have tried tinys3, boto3, and boto original flavor. tinys3 worked like a charm in localhost, but if I'm even importing the file when I load it with Elastic Beanstalk I get an error much like what I get from boto3 when I do the same (except boto3 lets me get as far as launching the server and initiating the xml upload from the client): invalid syntax (_base.py, line 381) Boto original doesn't work at all. I definitely need the ability to upload XML's dynamically to S3. No idea why this won't work. -
AJAX for adding product from a page of multiple products not working in Django templates
I have a template in Django having multiple products for a user to add to cart. The code for the template is below. {% for object in fruits_and_vegetables %} <div class="col-sm-3"> <form class = "submit-form" id = "{{ object.id }}" method="GET" action="{% url 'my_virtual_supermarket_products:my_virtual_supermarket_cart' %}"> <img src="{{ object.image.url }}" width="120" height="120"> <h5 style="color:black">{{ object.name }}</h5> <h5 style="color:black "><i class="fa fa-eur" aria-hidden="true"> {{ object.price }}</i> </h5> <input type="hidden" name="item" value ={{ object.id }}> <input class="form-group" type="number" name="qty" value="1" style="width:25%;text-align: center"/> <input type="submit" class="btn btn-primary submit-btn" id = "{{ object.id }}" value = "Add to cart"> </form> </div> {% endfor %} I am trying to make an AJAX call, so upon adding products to cart the page doesn't need to be refreshed. My jquery code looks like this <script> {% block jquery %} $(".submit-btn").click(function (event) { event.preventDefault(); var formData = $(".submit-form").serialize(); console.log(formData) }); {% endblock %} </script> When I console log the formData, it basically shows me all the products with their item id and quantity. Below is how my console log looks like item=1&qty=1&item=3&qty=4&item=7&qty=1&item=9&qty=1&item=10&qty=1&item=26&qty=1&item=27&qty=1&item=31&qty=1&item=32&qty=1&item=2&qty=1&item=13&qty=1&item=18&qty=1&item=25&qty=1&item=4&qty=1&item=8&qty=1&item=11&qty=1&item=19&qty=1&item=20&qty=1&item=21&qty=1&item=23&qty=1&item=24&qty=1&item=6&qty=1&item=14&qty=1&item=15&qty=1&item=16&qty=1&item=22&qty=1&item=29&qty=1&item=5&qty=1&item=12&qty=1&item=17&qty=1&item=28&qty=1&item=30&qty=1 How can I get only the relevant product chosen through the serialize method ? -
Django Reverse Error: NoReverseMatch at
Hello StackOverFlow Members, before i get down to the point, let me retrace my thought/process here to help further slim down my issue. When i click a location object in "location_tree.html" it would redirect me to a new page, "accounts/location/(?P\d+)/" or "location", displaying the location name and its type. From the very same page, the name would be a hyperlink to another page with more details about the "location". But when i attempt to click the name, it redirects me to this error: NoReverseMatch at /accounts/location/2/ Reverse for 'continent' with keyword arguments '{u'pk': 2}' not found. 1 >pattern(s) tried: ['accounts/location/(?>P\d+)/location_continent/(?P\d+)/'] Some key things to note, i am using python2.7.

How to make migrations only one app inside project using django
I have the follow project structure: MyProject |--myBaseApp | |--migrations | |--__init__.py | |--models.py | |... |--myClientApp | |--migrations | |--__init__.py | |--models.py | |... |--myProject | |--__init__.py | |--settings.py | |--urls.py | |... |--manage.py |... I can import to myClientApp/models.py the models.py from myBaseApp, but when I use the commands on terminal mode: python manage.py makemigrations python manage.py migrate myClienteApp The Django creates, on data base, all tables from models.py, both myClienApp/models.py and myBaseApp/models.py.

Learning to work with HTTP requests in Python 3
I would first kindly like to express my gratitude to all people that are taking the time to read this post and/or respond to it! As a novice "developer" I only recently found out about this website and the professional highly skilled members that are present here impress me in every question I read. So thank you for that! For my question; I recently started with python (3.6 in PyCharm Professional) and am in the process of building an web application on the Django framework (although right now I am exploring the Flask framework). My problem is that I can't seem to get my head around HTTP Requests (aka, making my front-end of the web application connect to my serverside and server-hosted Python scripts). I read the Python and Django documentation and watched multiple video tutorials on youtube that were well reviewed but still can't wrap my head around it. What I am looking for is a link to a clear description with preferably a tutorial that focuses solely on HTTP requests so I can make myself familiar with it. Does anybody knows a good source or has had the same problem in the past and overcame it? I would … -
trouble iterating through dictionary keys and values in django template
I am trying to iterate through a context dictionary in a template in django. So far I've been unsuccessful and I'm not understanding what it is wrong. This is my view: def main_view(request): cat_dict = {'Other': 0, 'Meeting': 0, 'Project 1': 0, 'Project 2': 0, 'Project 3': 0, 'Project 4': 0, 'Collaboration 1': 0, 'Collaboration 2': 0, 'Collaboration 3': 0, 'Process 1': 0 } my_dict = gCalScriptMain.gCalScript(cat_dict) return render(request, 'gCalData/gCalData_main.html', context=my_dict) Instead, this is my template: {% extends "base.html" %} {% block content %} <div class="jumbotron index-jumbotron"> <h1 id="main-title">gCalData</h1> <ul style="color:white"> {% for k,v in my_dict.items %} <li>{{ k }}: {{ v }}</li> {% endfor %} </ul> </div> {% endblock %} But I get nothing (not even an error). The only thing I can do is retrieve a single value if I put this in the template: {% extends "base.html" %} {% block content %} <div class="jumbotron index-jumbotron"> <h1 id="main-title">gCalData</h1> <p style="color:white">{{ Other }}</p> </div> {% endblock %} -

Python Social Auth authenticating users to wrong accounts
For some reason users while using Facebook to oath, the user will auth as random users. When I looked into the UserSocialAuth table there was one user who had over 700 UserSocialAuth records, (there were a dozen users with over a hundred Facebook UserSocialAuth instances). At first I thought this might be a symptom of some Facebook users not having emails (emails are our username). I don't think this is the issue any more, because then they would all be authenticating to the same user. Users are reporting being connected to different users. The pipelines we're using is this SOCIAL_AUTH_PIPELINE = ( 'social_core.pipeline.social_auth.social_details', 'social_core.pipeline.social_auth.social_uid', 'social_core.pipeline.social_auth.auth_allowed', 'social_core.pipeline.social_auth.social_user', 'social_core.pipeline.user.get_username', 'social_core.pipeline.social_auth.associate_by_email', 'social_core.pipeline.user.create_user', 'apps.accounts.pipeline.validate_user', 'social_core.pipeline.social_auth.associate_user', 'social_core.pipeline.social_auth.load_extra_data', 'social_core.pipeline.user.user_details', ) The custom functions in the pipeline are these: def validate_user(strategy, user, response, details, is_new=False, *args, **kwargs): if not user.validated_at: user.validated_at = timezone.now() user.save() We are using the email field as our username, if that matters.
