How can I add a "snooze" button in Django with Ajax?
In my Django app I want to have a snooze button, which I want to use in order to postpone a deadline for an object. The corresponding model has a datefield called alarm and I want to pass the snooze command together with a number x of days that should be added to the current setting. So far I found out that I cannot do this directly from the template and multiple sites suggested the use of Ajax. I have never used that. My files look like this. views.py def Operation_Snooze_Method(request): print(request) if request.POST: if request.is_ajax(): print("Ajax") # I guess here I would handle the alarm if I could bring the Ajax call to work at all. else: print("no ajax") print(request.POST) return render(request, templ_folder_name + landingpage) part of my models.py class Operation(models.Model): title = models.CharField(max_length=255, blank=False, null=False, verbose_name="Title of the operation") alarm = models.DateField(verbose_name="Date of the alarm", null=True, blank=True) [...] def Operation_Snooze(self,x): self.alarm = datetime.now() + timedelta(days=x) urls.py path('snooze/', views.Vorgang_Snooze_Method, name="snooze"), my base.html, which is the template that I extend with my other templates $document.ready(function(){ $("#snooze").submit(function(event){ event.preventDefault(); $ajax({ type:"POST", url:"{% url 'app_name_myproject:snooze' %}", data:{ 'id':$('#snooze').val() 'csrfmiddlewaretoken':$("input[name=csrfmiddlewaretoken]").val() }, }); return false; };) }); </script> [...] {% if urgent_operations %} # this … -

Get Bounding Box from Django PolygonField

Django create field in ModelForm if condition is True
I am going to have a Product, which can have some variations, and also Product, which has no variants. So for the first case, there should be fields 'quantity' and 'variant' select box rendered. For the second case, only a field with 'quantity' should be rendered because the product has no variants. Is possible to do that somehow with ModelForms?

Django - make signal wait for file to be ready
Im experiencing a wired issue using Django signals. Each time a user saves a new avatar onto his profile also a thumbnail version of the picture gets saved beside the high quality version. This is working fine until the image should get changed or delted, here I have written two signals to handle both fileds, the avatar and the avatar_tn field. For some reason my signals are working sometimes and sometimes not, especially they have problems if the underlining filesystem is remote, like NFS, CIFS or iSCSI. It seems that the signal always expects that the file is ready and already written, which is obviously not the case due to network and I/O-Delay ... signals.py # Runs on avatar deletion @receiver(models.signals.post_delete, sender=User) def avatar_auto_delete_files(sender, instance, **kwargs): if instance.avatar: if os.path.isfile(instance.avatar.path): os.remove(instance.avatar.path) if instance.avatar_tn: if os.path.isfile(instance.avatar_tn.path): os.remove(instance.avatar_tn.path) # Runs on avatar change @receiver(models.signals.pre_save, sender=User) def avatar_auto_delete_files_on_change(sender, instance, **kwargs): if not instance.pk: return None try: old_avatar = sender.objects.get(pk=instance.pk).avatar old_avatar_tn = sender.objects.get(pk=instance.pk).avatar_tn except sender.DoesNotExist: return None if not old_avatar: return None new_avatar = instance.avatar new_avatar_tn = instance.avatar_tn if not old_avatar == new_avatar: if os.path.isfile(old_avatar.path): os.remove(old_avatar.path) if old_avatar_tn == new_avatar_tn: if os.path.isfile(old_avatar_tn.path): os.remove(old_avatar_tn.path) Is there any way I can make the signal wait for … -

Table doesn't exist, when in reality it does

Anyways, when i go to main page it says this (1146, "Table 'build1.building_access_product' doesn't exist") So my reaction would be to go to admin and make a product. And so I did, but it gave me the same error. So i went over to database to check if IT DOESN'T EXISTS, and as you can see from show tables;. It does exists.. So, any ideas? -

My React app is repeating the same error when using socket.io
I'm putting together a React web-app that uses Django for the backend server, coded in Python. At the moment, I'm attempting to change the data on a page when a new user joins. This is everything I have on the frontend to get this working: import io from 'socket.io-client'; let socket = io('http://127.0.0.1:8000'); class Room extends Component { constructor(props) { super(props); this.state = { chat: [{message:'Hello everyone'}] }; } componentDidMount() { socket.on('receive', data => { console.log(data); this.setState({chat:[...this.state.chat,data]}); }) } msgthreads = () => { return this.state.chat.map((msg, index)=>{ return <div key={index}> <p>{msg.message}</p> </div> }); } sendmessage =()=> { console.log(this.textInput.value); socket.emit('send',{message:this.textInput.value}); } some irrelevant code... render(){ return ( <div> {this.msgthreads()} </div> <div> <input type="text" className="form-control" ref={(input) => { this.textInput = input; }}/> <button onClick={this.sendmessage}>testbutton</button> </div> } export default Room; But this is the error that I'm getting: GET http://127.0.0.1:8000/socket.io/?EIO=4&transport=polling&t=NWlvd71 404 (Not Found) The error just keeps happening every few seconds, even when I'm doing anything. Is there something I have to do on the backend to get this working or is this a problem with the code above? -
Bootstrap 'row's not working but 'col's do
As the title says, I am pretty sure I set up bootstrap correctly and everything but running this page it shows me all the correct divs and and sized columns, however all the 'row' tags are ignored. they are just thrown all over the place. Shouldnt they be stacked one ontop of the other? I really dont want to hard code positions, i want this to be responsive. I have some CSS attatched to this but its the bootstrap giving me issues. <body> {% block body %} <div class='row banner'></div> <div class='row header'> <div class='col-4 image'></div> <div class='col-8 bio'></div> </div> <div class='row profile'> <div class='col-3' style='justify-content: center; align-items:flex-start;'></div> Followers <div class='followers'></div> <div class='col-6'></div> <div class='feed'></div> <div class='col-3' style='justify-content: center; align-items:flex-start;'> Following <div class='following'></div> </div> {% endblock %} </body> -
send Data from react to django rest api
after a lot of searching i keep finding how to send Data from react to django api using classes not functions so how would i convert this for exmaple to a functional component (this is not my code, just an example) export default class CreateRoomPage extends Component { constructor(props) { super(props); this.state = { guestCanPause: this.props.guestCanPause, votesToSkip: this.props.votesToSkip, errorMsg: "", successMsg: "", }; this.handleRoomButtonPressed = this.handleRoomButtonPressed.bind(this); this.handleVotesChange = this.handleVotesChange.bind(this); } handleGuestCanPauseChange(e) { this.setState({ guestCanPause: e.target.value === "true" ? true : false, }); } handleRoomButtonPressed() { const requestOptions = { method: "POST", headers: { "Content-Type": "application/json" }, body: JSON.stringify({ votes_to_skip: this.state.votesToSkip, guest_can_pause: this.state.guestCanPause, }), }; fetch("/api/create-room", requestOptions) .then((response) => response.json()) .then((data) => this.props.history.push("/room/" + data.code)); } renderCreateButtons() { return ( <Grid container spacing={1}> <Grid item xs={12} align="center"> <Button color="primary" variant="contained" onClick={this.handleRoomButtonPressed} > Create A Room </Button> </Grid> </Grid> ); } }
