ProgrammingError at /admin/mysite/photo/

when opeing in development everything is ok but when i open from admin site (production) to add new photo i get:

relation "mysite_photo" does not exist LINE 1: SELECT COUNT(*) AS "__count" FROM "mysite_photo"

and the main site will give error:

relation "mysite_photo" does not exist LINE 1:"."doc_file", "mysite_photo"."description" FROM "mysite_ph... ^

here is my photo model:

class Photo(models.Model):
	category = models.ForeignKey(Category_docs, on_delete=models.SET_NULL, null=True)
	image = models.ImageField(upload_to='docs_images/',null=False, blank=False)
	doc_file = models.FileField(upload_to='docs_files/',null=True, blank=True)
	description = models.TextField(default="none")

	def __str__(self):
		return self.description

and this line in docs.html is causing the error:

{% for photo in photos %}
        <div class="col-md-4">
        <div class="card my-2">
	<img class="image-thumbnail" src="{{photo.image.url}}" alt="Card image cap">
	<div class="card-body">
	<small>Name: {{photo.description}}</small>
	<small>Category: {{}}</small>
	<a href="{% url 'detail' %}" class="btn btn-outline-dark btn-sm m-1">View</a>
	{% empty %}
	<h3>No Files to show!</h3>
	{% endfor %}

and this is the function in

def docs(request):

	category = request.GET.get('category')
	if category == None:
		photos = Photo.objects.all()
		photos = Photo.objects.filter(category=category)

	categories = Category_docs.objects.all()
	context = {'categories': categories, 'photos':photos}
	return render(request, 'docs/docs.html', context)

Hi rwahdan1978, the part of the error that says, relation "mysite_photo" does not exist indicates that the table doesn’t exist in the database. Did you commit your migrations and run them in your production environment (python migrate)?
