I have created a Django application and initially the code worked perfectly but when I restarted the development server I started having 'module' object not iterable exception. This is my code

views.py

import datetime
from django.contrib import messages
from django.shortcuts import render
from forms.forms import *
from django.core.mail import send_mail
from django.http import HttpResponse
from patients.models import *


def doctor_view(request, id):
    patients = Patients.objects.get(id=id)
     if request.method == "POST":
            form = DoctorForm(request.POST)
            if form.is_valid():
                f = form.save(commit=False)
                date = datetime.datetime.now()
                f.date_seen = date
                f.save()
                messages.info(request, 'patient profile was successfully updated !!!')
        else:

            form = DoctorForm(instance=patients)
            date = datetime.datetime.now()
        return render(request, 'doctors/templates/patient_registration.html',
                      {'form': form, 'title': 'Patient Treatment', 'patients': patients, 'date': date, 'messages': messages})

urls.py

from django.urls import path

from . import views


urlpatterns = [
    path('<int:id>/', views.doctor_view, name='doctor-views'),
  
]

TypeError: 'module' object is not iterable

I am passing the values to the template using a dictionary and my html template is as follows. I have also installed django-crispy-forms.

{% extends 'patients/templates/base.html' %}
{% load crispy_forms_tags %}
{% block content %}
<form action="" method="post">
    {% csrf_token %}

    <div class="col-sm-12 col-md-12 col-lg-12 d-flex flex-column" style="margin-lef:auto; align-items:center; justify-content:center">
           <div class="col-sm-12 col-md-8 col-lg-8">
               <h4 class="mt-3 mb-2">Patient Treatment</h4>
               <hr class="my-4">
           </div>
            <div class="col-8 d-flex" style="border:1px solid #dfdfdf;z-index:20;color:maroon">
                <h1 class="lead" style="margin:20px;">Treating: </h1>
                <h6 class=" lead " style="margin:20px;" >Name:   {{ patients.name}}</h6> <h6 class=" lead " style="margin-top:20px;" >{{ patients.surname}}</h6>
                <h6 class=" lead " style="margin:20px;" >Nat ID:    {{ patients.id_no}}</h6> <h6 class=" lead " style="margin-top:20px;" >Gender:    {{ patients.gender}}</h6>
                 {% for message in messages %}
                <div  class="alert alert-{{ message.tags }}" role="alert" style="color:#0e466b;;"> {{ message }}</div>
                {% endfor %}
            </div>
            <div class="col-sm-12 col-md-8 col-lg-8">
                {{ form.symptoms|as_crispy_field }}
           </div>
          <div class="col-sm-12 col-md-8 col-lg-8">
                {{ form.disease|as_crispy_field }}
           </div>
          <div class="col-sm-12 col-md-8 col-lg-8">
                {{ form.treatment|as_crispy_field }}
           </div>
        <div class="col-sm-12 col-md-8 col-lg-">
                 <input type="submit" value="Send to Doctor" class="btn btn-success btn-sm">
                 <a href="email" class="btn btn-info btn-sm ml-3">Send email</a>
                 <hr class="my-4">
                <center> <h6 class="  " style="margin:20px;" >  {{ date}}</h6></center>
            </div>
    </div>

The problem is in your context dictionary. Django automatically adds a messages object to the request context without you needing to add it manually (assuming you have MessageMiddleware enabled). What you're doing at the end of your dictionary is overriding that object with the module messages that you imported at the top of your file.

Simply removing the key-value pair 'messages': messages from your dictionary should fix the issue.

# ...
return render(request, 'doctors/templates/patient_registration.html',
                      {'form': form, 'title': 'Patient Treatment', 'patients': patients, 'date': date})
