Dynamic Facebook Like
I have a news app on my website. I added a Facebook like button on every news/post page but i can’t get it working correctly. When I click on the like button, it changes state which is ok but changes are not affected - displayed on the actual Facebook page. Can anybody share their experiences? This is what i tried so far <div class="fb-like" data-href="https://www.facebook.com/mysite.com/posts/" data-layout="button" data-action="like" data-size="large" data-show-faces="false" data-share="true"> </div> and <div class="fb-like" data-href="https://www.facebook.com/mysite.com/news/{{ object.title }}" data-layout="button" data-action="like" data-size="large" data-show-faces="false" data-share="true"> </div> -

Recommend stack for my python app
I wrote a Python script which checks the price of a stock and sends an SMS when the price increased or decreased by a certain amount within a day. The process is repeated every 10 minutes. At the moment it uses a the sleep function but it might be better off with a cron job. I want to run this app on a raspberry I want to build a web interface which shows the status and has a kill switch Can you recommend a stack to use for this? I started working in Django but I've realized that I need to plan this better. -
Django REST Framework Serializer output
I'am new to Django and DRF, but I'am trying to use DRF's Serializer to override djosers default user registration behavior. (djoser = a DRF lib for user registration/login/password reset etc.) I've djosers view, that uses a serializer to create user objects def perform_create(self, serializer): user = serializer.save() My idea was to override this serializer to achieve the following: create the user create an account object in parallel login the user return the account object alongside with the auth token in one response The last point gives me trouble because I don't know how to achieve such custom behavior in the serializer. I made the input fields readonly, so they are not included in my response. In the save method a create a user + account object, logging in the user and then I return the user (which is needed by the view) How do I serialize just the created account object with the created token string into one response? This is my serializer (simplified and stripped from some stuff, but that's basically it) class UserRegistrationSerializer(serializers.Serializer): email = serializers.EmailField(write_only=True) # some other fields password = serializers.CharField(style={'input_type': 'password'}, write_only=True, validators=settings.get('PASSWORD_VALIDATORS') ) # this should be the output account = Account(read_only=True) def save(self): … -

Am I doing it wrong or django rest api framework / coreapi has a bug ?
I'm experiencing some troubles about the coreapi and django rest api, perhaps someone can help me to understand what is wrong.

How to refer a column that matches a foreign key in another table in Django?

Use Celery or Pika for Text Messages in Django / Rabbitmq environment?
Celery and Pika both utilize rabbitmq. I'm making a django app that does text messaging in an asyncronous environment. My inner developer says "Try to use Celery for both, since it uses rabbitmq." But another voice says " Use Pika along with Celery for their particular strengths -- celery for the multitasking, and pika for messaging. I'm a perfectionist -- Does celery do straight-up messaging like Pika does? Or should should I use Pika and Celery, both communicating with Rabbitmq? I have done extensive research, and for some reason I cannot find an example of using Celery to send text messages. Any guidance on this would be appreciated. This is not an opinion question - this is to find out if using Celery for text messaging is stupid. -

Django: Model query extract not looping in template
So, I'm making this app in django and using this code: My template tag in video_select.py file: @register.assignment_tag def content_list(): contentlist = vvideo.objects.all() return contentlist My template: {% load video_select %} <article id="menu" style="height:80%;"> <h2 class="major">Menu</h2> <div> {% for contentt in content_list %} {{ contentt.video_path }} {% endfor %} </div> <h2 class="major">End Menu</h2> </article> This displays nothing. But I'm not sure why. Conversely, simply printing out {% content_list %} does print out this output: [<vvideo: vvideo object>, <vvideo: vvideo object>, <vvideo: vvideo object>, <vvideo: vvideo object>, <vvideo: vvideo object>, <vvideo: vvideo object>] So clearly the template tag is working. My models.py contains: class vvideo(models.Model): video_path = models.CharField(max_length=200, blank=True, null=True) so, clearly the .video_path reference is also correct. Can you help me understand why my list isn't looping & printing out? I tried iterating it directly in the template tag and it is working. However, I really want the loop to run in the template itself because I am trying to create href links for each video. So, I need to loop through all videos in the database and extract their names and urls, creating respective links. That's two items required for each line output: therefore, it's probably better to send … -
json_response_message() got multiple values for keyword argument 'response' - django
I am getting this error json_response_message() got multiple values for keyword argument 'response' I figured how I get this error though but I just cannot find out a workaround for this, is there anyone able to give me a hand? the reason for this error is because of this line return json_response_message(success_response(), response=response) these are the two functions I created and they work fine though, def json_response_message(response, **kwargs): data = {} print(response) print(kwargs) data.update(response) data.update(kwargs) return JsonResponse(data) def success_response(*args): # initial message to ok message = 'OK' # if there is *args then add this to the message if args: for value in args: message += value return { 'status': True, 'code': 200, 'message': message } I figured if I do something like this, everything would work fine return json_response_message(success_response(), change_this=response) is it because response is a reserved word or something? either way, is there a way I can still make it happen to be response=response ? Because all the structure in front end has already been set up. I don't really want to change anything if I don't have to as long as I have some workaround on my side. Can someone please give me a hand? Thanks in … -

Protection From Browser Dev Tools Changing POST Values
After looking around for a bit, I cannot seem to find an answer to my question... Or maybe I am just not wording my question correctly in my search. Any-who, my question and description is as follows: I am building a web application using Django, Javascript, HTML, and all that Jazz. I am currently testing my checkout page and noticed a security issue I do not know how to handle. Issue: I can open up developer tools and change the 'value' of whatever I want on my HTML and that is the value that ultimately gets passed back in the POST request. How do I make it so that changing the HTML values using dev tools on the browser doesn't effect the values being sent back? -
