django AJAX POST action that redirects user to login URL if not logged in
I am using django 3.2 I am trying to implement functionality that I have seen on other websites - where when you try to comment (for example), without login, it redirects you to the login page. It is trivial to do this for GET routes - however, it is not clear to me, how to implement this functionality for AJAX POST functions. Example: /path/to/myapp/views.py class FoobarMixin(LoginRequiredMixin, UserPassesTestMixin): def test_func(self): user = self.request.user if user.is_superuser: return True return some_foobar_test() class FooCreateView(FoobarMixin, CreateView): http_method_names = ['post'] context_object_name = 'foo_object' def get_object(self, queryset): content_type = self.request.POST.get('ct') object_id = self.request.POST.get('id') self.foo_object = get_object_by_content_type_and_object_id(content_type, object_id) return self.foo_object def post(self, request, *args, **kwargs): foo_object = self.foo_object retval = foo_object.just_do_it(self.request.user) new_count = foo_object.foo_count if retval else None return JsonResponse({'retval': retval, 'new_count': foo_count}) /path/to/myapp/urls.py ... path('whatever/foo/', views_foo.FooCreateView.as_view(), name='do-foo'), ... /path/to/myapp/templates/myapp/page.html {% extend 'base.html' %} {% load static %} {% block content %} <a class="foo"><i class="foo fa fa-smile-o</i></a> {%end block %} {% block body_js %} $('a.foo, a.foo > i').on('click', function(e){ $.ajax({ type: "POST", url: "{% url 'do-foo' %}", data: { ct: '{{ content_type }}', id: '{{ foo_id }}', csrfmiddlewaretoken: '{{ csrf_token }}' }, dataType: "json", success: function(resultData){ console.log(resultData); }, error: function(xhr, status, error) { console.log(status); console.log(`error from server: ${status}`); … -

how to reduce list chart to one and use select dropdown to show selection without refresh page?
I am a beginner learning to make charts with pandas converted in json format. I have a lot of graph against the data, but it takes a lot of space; so i would like to know how can i make a filter and only display what the user want to see. I read some tutorial that made with dropdowns with html, but the problem is that I have to do this dynamically and depending on the size of the data, do you have any suggestions for the process? var trend_axe = {{trend_axe | safe}}; for (i in trend_axe){ var item = JSON.parse(trend_axe[i]); var label = []; for (j in item){ label.push(item[j].date_); } var stock = []; for (k in item){ stock.push(item[k].stock); } new Chart(document.getElementById(item[i].axe),{ type :'line', data :{ labels: label, datasets: [{ label: 'Trend journalier des ventes', data: stock, fill: false, borderColor: '#0E9036', tension: 0.1 }] }, }); }; what i could do : <div class="chart"> <canvas id="MDVS1"></canvas> <canvas id="MDV03"></canvas> <canvas id="MDV01"></canvas> <canvas id="MDV04"></canvas> </div> -
Collapse Django NavBar on Hover (Mouse out)
I am in need to hide a django app navbar on mouse out and show on mouse over just like in 1. The django app is using Bootstrap4. According to W3School BootStrap4 has .collapse class 2. From a BootStrap4 perspective, I am still figuring out I could use the collapse class with hover. On the other hand, by just using css, I went through the first attempt following something like in 3. HTML <div id="nav_general"> <nav id="navbar" class="navbar navbar-inverse navbar-fixed-top" role="navigation"> </nav> </div> CSS .home #navbar { display: flex; transform: translateY(-100%); } .home #nav_general:hover #navbar { transform: translateY(0); } Within the CSS configuration the navbar was hidden forever and it is not expanding on mouse over. Could anyone point me the reason the navbar has been hidden forever and how I could make it expand on mouse over? How I could achieve the same goal by just using BootStrap4 class=collapse? -

Accessing primary key in Django class based view

Django Models create a task for all users
So i'm trying to build a webapp where the same task is given to all users, and when the users complete the task they can mark it as completed, to do so i added a 'status' bool that is set to true when the 'task' is not complete, and with a button the user can set it to false, the problem is that when i use a many-to-many field, if one user changes the 'status', it changes for everyone. I also tried using a Foreignkey but if i use a Foreignkey i have to create a task for every user. What i want is to create a task, assign it to all users, and then all the users can interact with the task without affecting what other users see.

How to deploy webpack generated html file?
I run webpack to generate the js/css for my Django app, and it generates two things: (1) transpiled, packed, and versioned js/css files under myapp/static/myapp/ (the versioning uses the hased content of the file, e.g. myapp.7dd0fe49a6586234d7e7.min.js). (2) Since the version specifier is not very human friendly, and to make sure all files are included, the following file is created as myapp/templates/myapp/include-scripts.html: {% load staticfiles %} {% if debug %} <script src="{% static "myapp/js/myapp.min.js" %}"></script> <link rel="stylesheet" href="{% static "myapp/css/myapp.css" %}" type="text/css"> {% else %} <script src="{% static "myapp/js/myapp.7dd0fe49a6586234d7e7.min.js" %}"></script> <link rel="stylesheet" href="{% static "myapp/css/myapp.dd0a677adcba9309426a.css" %}" type="text/css"> {% endif %} This way production usage will get the versioned files, and consumers of myapp can include the the latest version of the generated files by simply: {% include "myapp/include-scripts.html" %} Now I want our gitlab pipeline to automate the process.

Fisrt of all sorry for the long question. Since Vue JS performance is very good as compared to some of other platform (Based on test criteria). I render some html to a span through axiom response. But button (in the response html) click not working and also vue js data also not displaying. Here is my code <div id="vue-app" class="container"> {%csrf_token%} <button v-on:click="greet" class="btn btn-primary">BUTTON</button> <span v-html="message"></span> </div> <script type="text/javascript"> let app = new Vue({ el: "#vue-app", delimiters: ['[[', ']]'], data: { message: "", }, methods: { greet: function (event) { let formData = new FormData(); formData.append('csrfmiddlewaretoken', document.getElementsByName('csrfmiddlewaretoken')[0].value); axios({ method: 'post', url: '{% url "core:test_url" %}', data: formData }).then( response => (new Vue.set(this, 'message', response.data)) ); } } }); </script> Django view class test_func4(View): def post(self, request): return render(request, 'home/vue_js_axiom.html', { "post_to_view": 123 }) vue_js_axiom.html <table class="table table-striped"> <tr> <td>DATA FROM DJANGO VIEW</td><td>DATA FROM VUE JS</td> <td>ON CLICK BUTTON</td> </tr> <tr> <td>{{post_to_view}}</td><td>[[vue_js_variable]]</td> <td> <button v-on:click="click_from_response_view" class="btn btn-warning btn-sm">ON CLICK</button> </td> </tr> </table> <script> let container = new Vue({ el: '#container', delimiters: ['[[', ']]'], data: { vue_js_variable: "true", }, methods: { click_from_response_view: function (event) { alert("clicked from response view"); } }, }); </script> Can someone help to solve this problem?
