Not able send data to the database in Django

I wanna create a appointment system but its not working now. I'dont have a error actually i just have a error and it's coming from views.py (messages.warning(request,"ERROR!")). When i opened the page its coming anyway i just wanna send my informations.
models.py: I created models but im not sure for policlinic and doctor because it doesn't seems like charfield text. It's a option field in HTML.
class Randevu(models.Model):

It's my appointment page:
enter image description here

Because get method is used to render the page
and in views.py you dont write
if request.method=='GET':
As a result, the error message is executed while there is no error
add this :
if request.method=='GET':

How do I get images to show on my django app?

On my Django app, I am trying to make an eBay type of site that lets people post listings with pictures and bid on them. Everything works except posting an image. The image won't show and I do not know if it's the HTML or the python. If you have any questions let me know.
Html code:
{% extends "auctions/layout.html" %}
{% block body %}
<div class="container">
<h2>Create listing</h2>
</div>
<div class="container">
<form action="{% url 'submit' %}" method="POST">
{% csrf_token %}
<div class="form-group">
<label for="exampleFormControlInput1">Title</label>
<input type="text" class="form-control" id="exampleFormControlInput1" placeholder="Title of the lisiting..." name="title" required>
</div>
<div class="form-group">
<label for="exampleFormControlTextarea1">Description</label>
<textarea class="form-control" id="exampleFormControlTextarea1" rows="5" placeholder="Description..." name="description" required></textarea>
</div>
<div class="form-group">
<label for="exampleFormControlSelect1">Category</label>
<select class="form-control" id="exampleFormControlSelect1" name="category" required>
<option>Fashion</option>
<option>Tools</option>
<option>Toys</option>
<option>Electronics</option>
<option>Home accessories</option>
<option>Books</option>
</select>
</div>
<div class="form-group">
<label for="exampleFormControlInput1">Initial Bid</label>
<input type="number" class="form-control" id="exampleFormControlInput1" placeholder="Starting bid..." name="price" required>
</div>
<div class="form-group">
<label for="exampleFormControlInput1">Image link (optional)</label>
<input type="text" class="form-control" id="exampleFormControlInput1" placeholder="https://blah-blah.jpg..." name="link">
</div>
<button class="btn btn-outline-info" type="submit">Submit</button>
</form>
</div>
{% endblock %}
This is the python function for making listings:
def create(request):
try:
w = Watchlist.objects.filter(user=request.user.username)
wcount=len(w)
except:
wcount=None
return render(request,"auctions/create.html",{
"wcount":wcount
})

I'm Suffering with the problem in my django code for uploading the code of the image into the database?

Whenever i tried to upload the image through the form it gives me an error which is multivalue dictionary key error. GIVEN BELOW.....

Strange block/extends interaction going on in Django

so in my home page I extend from 2 things, based on whether or not the user is signed in or not. Then, if they have TRIED to sign in, and failed, i want the inputs to be red:
{% extends extendVar %} #in this case, extendvar=notLoggedIn.html
{% block signIn %}
{% if failure %}
<div class="form-group has-error">
<input type="email" id="email" name="email" placeholder="Email" class="form-control">
</div>
<div class="form-group has-error">
<input type="password" name="password" placeholder="Password" class="form-control">
</div>
{% endif %}
{% endblock %}
notLoggedIn.html then includes from a header page:
<div class="container" style="">
{% include 'header.html' %}
</div>
And this has a block tag:
<div class="header clearfix">
<nav>
<ul class="nav nav-pills pull-left">
<a class="" href="#">
<img alt="Brand" src="{% static 'images/Logo.png' %}" style="height:auto; max-width:470px; margin-top:-22px; margin-bottom:-30px; padding-right:10px;">
</a>
</ul>
<ul class="nav nav-pills pull-right">
<div id="navbar" class="navbar-collapse collapse">
<form class="navbar-form navbar-right" action="{% url 'signIn' %}" method="POST">
{% csrf_token %}
{% block signIn %}
<div class="form-group">
<input type="email" id="email" name="email" placeholder="Email" class="form-control">
</div>
<div class="form-group">
<input type="password" name="password" placeholder="Password" class="form-control">
</div>
<button class="btn btn-primary btn" href="" role="button" style="">Sign in </button>
{% endblock %}
</form>
</div>
</ul>
</nav>
Project name</h3> -->
my only problem is that because i am including header in NotLoggedIn, and then extending that, it doesnt preserve the block tags, and so the signIn blocks are not working. If instead of doing include header, i merely hard-code it, the blocks work perfectly. Any ideas?

According to the django documentation, when you use "include", blocks in the included template are evaluated first, and then substituted in. So in your template, you can't override a block of the included template.
https://docs.djangoproject.com/es/1.9/ref/templates/builtins/#include
Instead of using a block, what if you pass variables down to the include block, to get it to render how you want? For example:
Your template:
{% include 'header.html' with failure=failure %}
header.html:
<div class="form-group {% if failure %}has-error{% endif %}">
<input type="email" id="email" name="email" placeholder="Email" class="form-control">
</div>
<div class="form-group {% if failure %}has-error{% endif %}">
<input type="password" name="password" placeholder="Password" class="form-control">
</div>
