Compare context variable django

Question

How can I compare context variable in Django? I want to compare the name that I have saved in my model with request.user

{% if user %}
  {% for x in user %}
    {% ifequal x request.user %}
      <h1>working</h1>
    {% else %}
      <h1>false</h1>
    {% endifequal %}
  {% endfor %}
{% endif %}

I want the following comparison: {{x}} == {{request.user}}

Context dict

{"user": Prod.objects.filter().values_list('name', flat=True)}

User is here for example admin and request.user is also admin

My model:

class Prod(models.Model):
    description = models.CharField(max_length=300)
    price = models.DecimalField(max_digits=6, decimal_places=2)
    name = models.ForeignKey(User, on_delete=models.CASCADE)

Loop

I am using a context processor in the base.html

from farmer_page.models import Prod
def context_variable(request):
    # .values_list('name', flat=True)
    return {"user": Prod.objects.filter()}

Does this answer your question? Nested 'If' statement in jinja 'for' loop — shaik moeed

Does Prod table has data related to current logged in user if not {{ request.user.user_name }} will print nothing. — sandeep

Use if template tag in your templates:

{% if x == request.user %}

Edit

{% if user %}
  {% for x in user %}
    {% if x.name == request.user %}
      <h1>working</h1>
    {% else %}
      <h1>false</h1>
    {% endif %}
  {% endfor %}
{% endif %}

Prod contains multiple names like admin user1 user2 user3 so I still need to loop through it?

Pedram Over a year ago

Based on what you want to accomplish, you can either loop through it or use in template tag.

Giga Meta Over a year ago

{% if user in request.user %}                             <h1>working</h1>                             {% else %}                             <h2>false</h2>                             {% endif %}

This is not working I get false

Pedram Over a year ago

If you are looking for request.user in user: {% if request.user in user %}

Giga Meta Over a year ago

Still the same result false

Context dict:

{"user": Prod.objects.filter(condition)}

template

 {% if request.user in user %}
<h1>success</h1>
{% else %}
<h1>failed</h1>
{% endif %}

---------Edit----------

Always use related name in Foreign key

class Prod(models.Model):
    .
    .
    name = models.ForeignKey(User, on_delete=models.CASCADE, related_name='user_name')

views.py

{"user": Prod.objects.filter(condition)}

html template

{% if request.user.user_name in user %}
    <h1>success</h1>
    {% else %}
    <h1>failed</h1>
    {% endif %}

Yes I'm doing this but is it not working because user is a queryset?

sandeep Over a year ago

@GigaMeta what is model "Prod". Is this for users?

Giga Meta Over a year ago

Prod stands for Products, each "Prod" has a name and I filter them

sandeep Over a year ago

@GigaMeta Then this will not work. request.user is current logged in user. It will not match with instance of Product model.

@GigaMeta Is anything common in Prod model and User model?
