django2 - A like button per post. Ajax to submit the like button form but I have many forms with the same ID
In my template I'm looping through posts and for each post, a like button is placed for each post and this is working. I want the user to be able to like the post but I'm stuck and not really sure what to search for that might help solve this problem. I have a single ajax function, I want to be able to capture the submitted form so I can capture post ID values from that form. What seems to be happening is the first post works when I press the like button but the second post causes a page refresh and fails to fire the function. Thanks. <script type="text/javascript"> $(document).ready(function() { $("#like_toggle").submit(function(event){ event.preventDefault(); var id = $(this).attr('value'); $.ajax({ type: "POST", url: "/like" , data: { 'id': id, 'csrfmiddlewaretoken': '{{ csrf_token }}', }, success: function(){ $('#like-section').html("sent") } }); return false; }); }); </script> HTML <form method="POST" id="like_toggle"> {% csrf_token %} <div id="like-section"> <button id="like" value="{{ post.id }}" type="submit" class="btn btn-primary my-2 my-sm-0 btn-sm float-right">+Like<span class="badge badge-light ml-2">{{ post.likes }}</span></button> </div> </form> -
Nginx returning back (404 - Not found). Is this because of Gunicorn or Nginx?
So I am at a total loss with this. I am not sure where to start debugging this problem.I am not getting any nginx based logs.

Saving users mysql queries
We are writing a custom data analysis and visualisation tool that will allow users to pick a certain data range, set of data streams and perform aggregation functions on top of the filtered data. For each new query, we would like to give an option to the user for saving the query for later analysis. That means, we need to store several parts of the query, such as, columns, date ranges, aggregation functions (count, avg.) etc. Is there a Django/python library for this? -

Django Template - How to pass formset as an include variable
I am using a lot of formsets, so it is only natural not to copy paste a lot of template codes. To factor the commonality out, I made a add_formset.html file that renders the formset. This template works fine on its own. But, when I send a formset to it, it does not render the formset: Generic add_formset.html: <div class="container"> <div class="row pt-3"> <form method="post" action="" class="col-sm-12 col-md-9 col-lg-9">{% csrf_token %} {{formset.management_form }} {% for form in formset %} <div class="container"> <div class="col-sm-12 col-md-12 col-lg-12"> {% include 'card.html' with card_form=form %} </div> </div> {% endfor %} </form> </div> <div class="row"> <div class="col-6 p-2 ml-5" style="border: 0px solid cyan !important;"> <button type="submit" class="btn btn-primary ">Submit</button> </div> </div> </div> Using the generic formset template, I am passing the specific formset to it: {% extends 'base.html' %} {% load extra_template_tags %} {% block body %} {% include 'add_formset.html' with formset=unit_price_formset %} {% endblock %} I have also trie to replace formset=unit_price_formset with formset={{unit_price_formset}}, but it does not work. Any idea to solve this? -

Postgres not responding with high waiting time
I am using Django with Postgres. My site servers half a million pages without any issue and everything works fine. However I am using an API system and it works like below: First party calls my site with API, my site gets data from third website using API. My site extracts some data and pass it to First party. It works perfectly. In this cycle I have to check my Postgres whether data is already present or not. Everything works fine. But if third party API does not respond or there is any server issue with third party it takes long time to respond with 404 error, my postgres just dies and I have to run service postgresql restart command everytime to site work. What could be the issue? How do I check why Postgres is dying?
