Django site not updated
I got my django app configured with AWS S3 and all the media files are hooked up correctly. When I post a new article, the media files are stored in S3 and everything seems to work fine. After about 5 hours, I checked the site and it was back to a time frame where the article was not posted. This means it went back in time and got regressed to an earlier code? I don't know what is happening, and why after many days of testing it goes back to that one stage. Any advice? -
Django, twitter app, like/dislike feature for all the tweets:
As in title, i write a tweet-like app and i already have a feature for like/dislike each tweet. It works, but this is only for one tweet per page, like: <form action="{% url 'like_tweet' tweet.id %}" method="post"> {% csrf_token %} {% if is_liked %} <button type="submit" name="tweet_id" value="{{ tweet.id }}" class="btn btn-danger">Dislike</button> - {{ total_likes }} Likes {% else %} <button type="submit" name="tweet_id" value="{{ tweet.id }}" class="btn btn-primary">Like</button> - {{ total_likes }} Likes {% endif %} </form> With the view: class TweetDetailsView(View): def get(self, request, tweet_id): tweet = Tweet.objects.get(id=tweet_id) is_liked = False if tweet.likes.filter(id=request.user.id).exists(): is_liked = True stuff = get_object_or_404(Tweet, id=self.kwargs['tweet_id']) total_likes = stuff.total_likes() return render(request, "twitter/tweet.html", locals()) How can i obtain this same result for all the tweets in one html, like: {% if user.is_authenticated %} {% for t in tweets %} <table class="table1"> <br> <tr> <td> @{{t.user}} <br> <br> {{t.content}} <br> <br> {{t.creation_date}} <br> <br> <a href="{% url 'reply_to_tweet' t.id %}">Reply</a> <br> <br> <a href="{% url 'tweet' t.id %}">Details</a> <br> <br> <form action="{% url 'like_tweet' t.id %}" method="post"> {% csrf_token %} {% if is_liked %} <button type="submit" name="tweet_id" value="{{ t.id }}" class="btn btn-primary btn-sm">Dislike</button> - {{ t.total_likes }} Likes {% else %} <button type="submit" name="tweet_id" value="{{ t.id }}" … -
Styling Django Forms (Django-Countries)
I'm trying to place the form in the center but it doesn't seem to work. I have tried out inserting {{countries}} inside a div but still, it doesn't work. I'm sorry if this is such a dumb question but I don't have someone else to ask to. I know I'm doing something wrong in here but I can't quite pinpoint where is it I'm going wrong at.

How to store and display files and hyperlinks in angular + django application hosted on cloud foundry using sql server database
Hi I have question on possible ways of implementing file storage and retrieval in angular and django based application hosted on sql server. I have an application which is hosted on Cloud foundry and uses angular for UI and Django for APIs. The database being used is SQL Server. I need to implement a feature in which users can add their hyperlinks/files and can view the same at any point of time after addition. Currently I see an application with similar feature, in the database I could see the Hexadecimal values stored for the files/hyperlinks. In my understanding the UI should send the filepath to the API. And the API should run the SQL query like: INSERT INTO myimages values (1, (SELECT * FROM OPENROWSET(BULK N'FILEPATH', SINGLE_BLOB) as T1)) This should save the file as hexadecimal values. For displaying the file on user click on its name in UI, this stored haxadecimal values should be sent to UI. Is this appropriate way of implementing this functionality? What could be approach to achieve the same. Thanks -

Django Admin 404 - Media URLs?

How to solve AJAX not Getting JSON response from working URL?
I am using Django, I am trying to generate a JSON response from the views.py file to be received using AJAX. the code of AJAX in my html page is as follows: <script> $( document ).ready(function() { console.log("Inside the jQuery") var chart_data_entry = { 'item':[], 'value':[] }; console.log("Done with chart_data_entry") var objID = "{{plotID}}"; console.log("ObjID " , objID) var Json_Data = "/crm/GenerateChartData/" + objID + "/"; console.log("Json_Data ", Json_Data) $.ajax({ method:"GET", url: Json_Data, success: function(response){ console.log("RESPONSE => ",response) ; }, error: function (error_message) { console.log("Error: " + error_message); } }); }); Everything is working fine, the JSON Response sent from crm/GenerateChartData/All/ is functional, the only problem is that AJAX is not GET-ing from the url (crm/GenerateChartData/All/) and it is jumping straight to the error message, which I can't read because it says " Error: [object Object] " -
Wagtail: Add method to PageModel to get an inspect url

Is there a way? -
