Exploring new ideas through the lens of two variables in an HTML template, messages and users, a series of buttons trigger a jQuery function upon being clicked. This function sends a post request to a Django server, which then returns an update to the messages variable. Despite these efforts, the loop fails to update as expected. I even attempted to return a new HTML page with the updated variable, but the jQuery fails to refresh the entire page with the new HTML content.
If it's possible to update the variable independently, that would be optimal. Otherwise, is there a way for jQuery to incorporate the new HTML page instead?
The provided Python code handles updating the messages variable:
if request.method == 'POST':
send=Message.objects.filter(from_id=request.POST.get('userId'),to_id=2)
rec=Message.objects.filter(from_id=2,to_id=request.POST.get('userId'))
messages=sorted(chain(rec, send),key=lambda instance: instance.id,reverse=True)
print(messages)
return HttpResponse(list(messages))
As for returning a new HTML template:
m = Message.objects.filter(to_id=2).order_by('-id')
users = {}
for i in m:
if users.get(i.from_id.username) == None:
users[i.from_id.username] = User.objects.get(id=i.from_id.id)
users = list(users.values())
send=Message.objects.filter(from_id=users[0].id,to_id=2)
rec=Message.objects.filter(from_id=2,to_id=users[0].id)
messages=sorted(chain(rec, send),key=lambda instance: instance.id,reverse=True)
if request.method == 'POST':
send=Message.objects.filter(from_id=request.POST.get('userId'),to_id=2)
rec=Message.objects.filter(from_id=2,to_id=request.POST.get('userId'))
messages=sorted(chain(rec, send),key=lambda instance: instance.id,reverse=True)
print(messages)
return render(request,'psych.html',{"users":users, "messages": list(messages)})
return render(request,'psych.html',{"users":users, "messages": list(messages)})
Below is the HTML and jQuery code using the variable and attempting to update it:
function newUser(id){
$.ajax({
type: 'POST',
url:'/psych.html/',
data:{
userId:id,
},
success: function(data){
console.log(data);
$('#messageDiv').load(document.URL + ' #messageDiv');
}
})
}
{% for i in users %}
<li class="">
<button type="button" class="btn" onClick="newUser({{i.id}})">
<div class="d-flex bd-highlight">
<div class="img_cont">
</div>
<div class="user_info">
<span>{{i.id}}</span>
</div>
</div>
</button>
</li>
{% endfor %}
<!-- The varialbe that i'm trying to update is called messages bottom -->
{% for o in messages %}
{% if o.to_id.id != 2 %}
<div class="d-flex justify-content-start mb-4">
<div class="img_cont_msg">
</div>
<div class="msg_cotainer">
{{o.message}}
</div>
</div>
{% else %}
<div class="d-flex justify-content-end mb-4">
<div class="msg_cotainer_send">
{{o.message}}
</div>
<div class="img_cont_msg">
</div>
</div>
{% endif %}
{% endfor %}
If you encounter any challenges, refer to the previously successful method that updated messages using a form with a single variable:
$(document).on('submit','#submitMessage', function (e){
e.preventDefault();
$.ajax({
type: 'POST',
url:'/psych.html/',
data:{
message:$('#messageHolder').val(),
csrfmiddlewaretoken: $('input[message=csrfmiddlewaretoken]').val(),
},
success: function(data){
$('#messageDiv').load(document.URL + ' #messageDiv');
}
})
})
{% for o in messages %}
{% if o.to_id.id == 2 %}
<div class="d-flex justify-content-start mb-4">
<div class="img_cont_msg">
</div>
<div class="msg_cotainer">
{{o.message}}
</div>
</div>
{% else %}
<div class="d-flex justify-content-end mb-4">
<div class="msg_cotainer_send">
{{o.message}}
</div>
<div class="img_cont_msg">
</div>
</div>
{% endif %}
{% endfor %}
<form id="submitMessage" >
{% csrf_token %}
<div class="card-footer">
<div class="input-group">
<div class="input-group-append"></div>
<input name="message" class="form-control type_msg" placeholder="Type your message..." id="messageHolder">
<div class="input-group-append">
<button type="submit" class="btn">
<span class="input-group-text send_btn" ><i class="fas fa-location-arrow"></i></span>
</button>
</div>
</div>
</div>
</form>
